Understanding the additonal rate of tax
Navigating Additional Rate Tax in the Heart of London
As a resident or business owner in London, you may face unique challenges related to the Additional Rate tax. CIGMA Accounting understands the local nuances and will work with you to develop bespoke strategies to optimise your tax position while considering the specific requirements of the London tax environment.
Expert Guidance for Wimbledon and Farringdon Residents
If you’re situated in Wimbledon or Farringdon, our specialists are well-versed in addressing the tax implications specific to your area. We’ll tailor our advice to align with the local tax landscape, ensuring you benefit from the most relevant tax planning strategies.
The UK’s additional rate of Income Tax applies to income over £125,140, taxed at 45% on employment income, 39.35% on dividends, and 28% on residential capital gains. For many London professionals — lawyers in the City, consultants in Canary Wharf, or creatives in Soho — this threshold marks a steep increase in tax burden. Yet, it is also the threshold where strategic tax planning can unlock substantial savings.
The Context: Frozen Thresholds and Rising Incomes
The additional rate threshold has been frozen until at least 2028. As salaries and bonuses rise due to inflation and performance‑linked pay, more Londoners are slipping into the 45% bracket even without feeling wealthier in real terms. This phenomenon, known as fiscal drag, means that each pay rise may deliver diminishing net returns. For instance, an executive who earned £110,000 in 2021 and now earns £125,000 could find that almost all of that £15,000 increase is absorbed by tax and NI.
The 62% Tax Trap — Explained in Depth
Between £100,000 and £125,140, the personal allowance (£12,570) is gradually withdrawn: for every £2 earned above £100,000, you lose £1 of this allowance. That means that for each extra £1, you’re effectively taxed at 40% on income plus another 20% on the lost allowance, creating a marginal rate close to 60–62% before even accounting for National Insurance. This is one of the steepest effective tax bands in the developed world.
Illustration:
Earnings: £120,000
Loss of allowance: £10,000 × 40% = £4,000 additional tax
Effective marginal rate: 62% (including NI)
This trap particularly affects mid‑senior professionals in London who fall just above the £100,000 line — senior associates, architects, or consultants — because many do not consider themselves “high earners” yet still lose thousands unnecessarily.
Why Londoners Are Hit Harder
In London, higher living costs mean that the psychological gap between nominal and disposable income feels greater. Mortgage interest, private schooling, and commuting expenses amplify the pinch, making tax efficiency a necessity rather than a luxury. Additionally, Londoners often receive income in multiple forms — salary, bonus, dividends, or share options — increasing the complexity of their tax profile.
Strategic Solutions
Fortunately, several legitimate strategies can mitigate this squeeze:
Pension Contributions: Redirect part of income into pension savings to lower adjusted net income.
Gift Aid Donations: Charitable contributions can reduce taxable income and restore lost allowances.
Timing Bonuses: Deferring a bonus or dividend to the following tax year may keep income below the threshold.
Salary Sacrifice Arrangements: Exchanging part of salary for benefits like pension contributions or electric vehicles.
The Key Takeaway
Understanding where the marginal rate spikes and how it interacts with allowances is the cornerstone of intelligent tax planning. The additional rate should not be viewed as a punishment for success but as a signal to engage in structured financial optimisation. By combining foresight, compliance, and professional advice, London’s additional‑rate earners can transform what feels like a penalty into an opportunity for long‑term wealth preservation.

Pension Contributions — The Cornerstone of Tax Efficiency
For most additional‑rate earners in London, pension contributions are the single most potent and compliant method of reducing taxable income. They deliver a dual benefit: immediate tax relief today and long‑term wealth accumulation tomorrow. When structured intelligently, pensions can reclaim lost allowances, mitigate exposure to the 62% trap, and strengthen future financial independence.
Why Pension Contributions Are So Powerful
A contribution to a registered pension scheme directly reduces adjusted net income, which determines entitlement to the personal allowance and other reliefs. Every £1 contributed to your pension can effectively save up to 45p in tax, and in specific income ranges, over 60p when personal allowance recovery is included.
For example, if a London professional earning £120,000 contributes £20,000 into their pension, they could bring their adjusted income below £100,000. This manoeuvre restores the full £12,570 personal allowance and yields over £9,000 in combined tax relief and allowance recovery. In essence, it converts tax otherwise lost to HMRC into personal capital growth.
Mechanisms of Relief
Pension tax relief operates through a combination of relief at source (basic‑rate 20% added by the pension provider) and higher‑rate reclaim via the Self Assessment return. Additional‑rate taxpayers must claim the extra 25% (to reach 45%) themselves — an area frequently overlooked, resulting in missed relief.
Illustration:
A £10,000 personal contribution:
Pension provider adds £2,500 (basic‑rate relief).
Taxpayer reclaims another £2,500 via Self Assessment.
Effective cost: £5,000 for £12,500 invested.
Carry‑Forward: The Forgotten Goldmine
The carry‑forward rule allows you to use any unused annual allowances from the previous three tax years. With the current allowance at £60,000 per year, this could mean contributing up to £240,000 in one tax year while still obtaining tax relief. It’s especially valuable for those who have recently experienced high‑income years but underfunded their pension.
To qualify, you must have been a member of a registered pension scheme during those years. Accurate records and coordination with your accountant are crucial to avoid excess contributions and potential tax charges.
Navigating the Tapered Annual Allowance
High‑income Londoners — especially partners, directors, and executives — need to watch for the tapered annual allowance. When adjusted income exceeds £260,000, the standard £60,000 allowance begins to reduce by £1 for every £2 of excess income, with a minimum allowance of £10,000. This makes pre‑planning vital: scheduling contributions before bonuses or dividends are paid can preserve the full allowance.
Tip: Employers can make contributions directly, bypassing salary and saving National Insurance. Combining this with personal contributions creates a highly efficient balance between corporate and individual planning.
Beyond Tax Relief — Building a Long‑Term Asset
Pensions are not merely a short‑term tax shelter. They are a legally protected, tax‑advantaged vehicle for wealth accumulation. Growth inside a pension is free from Income Tax and Capital Gains Tax, and funds can be accessed flexibly from age 55 (rising to 57 in 2028). For Londoners juggling property and business assets, pensions provide diversification and security from market volatility.
Key Strategic Actions
Review your pension contributions each January–March before the tax year end.
Combine salary sacrifice and personal contributions for maximum relief.
Reclaim additional‑rate relief through Self Assessment without delay.
Monitor the Money Purchase Annual Allowance (MPAA) if you have already accessed your pension — it limits future contributions to £10,000.
Keep documentation: HMRC increasingly audits high‑value pension relief claims.
The Takeaway
Pension optimisation is the foundation of any additional‑rate strategy. It transforms taxation from a passive cost into an active component of wealth creation. For London’s ambitious professionals, the right pension strategy offers not only immediate relief but a disciplined path toward financial sovereignty.
Salary Sacrifice & Benefit Structuring
Salary sacrifice is one of the most versatile and underused strategies among additional‑rate earners. It allows employees to exchange a portion of their salary for non‑cash benefits provided by their employer. The traded portion of wages is not subject to Income Tax or National Insurance (NI), meaning both employee and employer can benefit simultaneously.
The Principle Behind Salary Sacrifice
When you opt for salary sacrifice, you agree to reduce your gross salary in return for an equivalent non‑cash benefit. Because your taxable pay decreases, you pay less tax and NI, and your employer may also save NI contributions. In well‑structured corporate settings, the employer can even reinvest part of their savings back into your benefits, creating a mutually beneficial arrangement.
For London’s high‑earning professionals, the value of salary sacrifice extends beyond immediate savings. It’s a strategic method for reshaping your compensation package to align with long‑term goals — whether that’s building pension wealth, accessing electric vehicles through company schemes, or supporting a healthier lifestyle through fitness and wellbeing benefits.
Common Salary Sacrifice Options
Employer Pension Contributions: The most effective use of salary sacrifice. By diverting pay into employer pension contributions, you bypass Income Tax and NI while boosting retirement savings.
Electric or Low‑Emission Cars: With the rise of electric vehicles, Benefit‑in‑Kind (BiK) rates are as low as 2% until 2025, making this one of the most tax‑efficient perks available.
Cycle‑to‑Work Schemes: A sustainable option that saves tax and NI on the value of bicycles and equipment used for commuting.
Technology and Mobile Devices: Some employers provide tax‑efficient access to laptops, phones, and tablets.
Additional Benefits: Extended health insurance, childcare vouchers (legacy schemes), and even gym memberships under specific corporate arrangements.
Numerical Illustration
Consider a London director earning £160,000 annually. They choose to sacrifice £10,000 of salary for additional employer pension contributions.
Income Tax saved: £10,000 × 45% = £4,500
Employee NI saved: £10,000 × 2% = £200
Employer NI saved: £10,000 × 15% = £1,500
If the employer reinvests half of their NI savings (£690) into the employee’s pension, the total effective benefit is £5,390 — a 55.9% uplift on the original sacrifice.
Advanced Applications for High Earners
Salary sacrifice can also interact positively with other strategies:
Pension Taper Management: By reducing your adjusted income through sacrifice, you can help preserve the full £60,000 annual allowance.
Avoiding Child Benefit Clawback: For households with children, bringing income below £50,000 reinstates full eligibility for Child Benefit.
Mitigating the 62% Trap: Sacrificing income to bring adjusted net income under £100,000 restores your personal allowance.
Corporate Directors: Directors of limited companies can structure a blend of lower salary, employer pension contributions, and dividends to balance tax efficiency and cash flow.
Employer Considerations
From an employer’s perspective, salary sacrifice enhances employee retention and can position a firm as progressive and environmentally conscious. However, the sacrifice must be formally documented and agreed upon in writing before it takes effect, and it cannot reduce pay below the National Minimum Wage. In sectors such as financial services, where bonuses and restricted stock units form part of remuneration, compliance with internal policies and HMRC guidance is essential.
Potential Pitfalls
Impact on Statutory Benefits: A lower salary can affect life cover multiples, mortgage affordability, or statutory pay (e.g., maternity or redundancy). Employees should model these effects before committing.
Rigid Contracts: Once implemented, mid‑year changes to a salary sacrifice arrangement are usually restricted unless there’s a “lifestyle event” (e.g., marriage, parental leave).
Employer Readiness: Not all payroll systems handle salary sacrifice seamlessly; proper configuration avoids administrative errors.
Strategic Takeaway
Salary sacrifice provides a means to convert mandatory tax deductions into customised benefits that align with individual lifestyle and financial goals. For London’s additional‑rate earners, especially those working for progressive employers, this structure is not merely about saving tax — it’s about re‑engineering compensation to deliver long‑term value and balance. Combined with pension planning and charitable giving, it forms a core pillar of an intelligent, compliant wealth strategy.
Gift Aid & Charitable Giving
Philanthropy and tax efficiency go hand in hand. For London’s additional‑rate earners, charitable giving not only supports meaningful causes but also serves as a strategic way to manage taxable income. The Gift Aid system allows donations to work harder — benefiting both the charity and the donor — while remaining fully aligned with HMRC regulations.
The Mechanics of Gift Aid
When you make a donation under Gift Aid, the charity can claim an extra 25p for every £1 donated, representing the basic‑rate tax relief. Higher‑ and additional‑rate taxpayers can then reclaim the difference between their highest tax rate and the basic rate through Self Assessment.
Example:
A London consultant donates £10,000 to a registered UK charity.
The charity reclaims £2,500, turning the donation into £12,500.
The donor reclaims the additional‑rate relief of 25% (the difference between 45% and 20%), equalling £2,500.
Net cost: £7,500 for a £12,500 gift — an instant 40% uplift for the cause.
Carry‑Back Opportunities
A unique advantage of Gift Aid is its carry‑back option. Donations made before 31 January following the tax year can be allocated to the previous year’s tax return. This flexibility is particularly useful if your income fluctuates — for example, if you expect to fall below the additional‑rate threshold next year but want to maximise tax relief while you still qualify.
Scenario:
A City banker makes a £5,000 donation in August 2025. By electing to carry it back to the 2024/25 tax year, they can reclaim 45% relief rather than the 40% relief applicable in 2025/26.
Gift Aid and Adjusted Net Income
Gift Aid donations reduce adjusted net income, the same metric that determines whether you lose your personal allowance. By donating strategically, a taxpayer earning just over £100,000 could bring their adjusted net income below the threshold, reclaiming the full allowance and unlocking an effective 60%+ marginal tax saving.
Illustration:
A designer in Kensington earns £110,000. By donating £8,000 under Gift Aid (grossed up to £10,000), they reclaim £2,000 in tax and restore £5,000 of personal allowance — saving an additional £2,000.
Total benefit: £4,000 saved on an £8,000 donation.
Eligible Donations and Common Misunderstandings
Only donations to registered UK charities qualify for Gift Aid. Overseas charities are generally excluded unless registered with HMRC.
Donations made through payroll giving are already deducted from gross pay and cannot be double‑claimed.
Non‑cash donations (goods, volunteering time) do not attract Gift Aid, though they can have a separate value for inheritance tax or accounting purposes.
Keep written records and charity receipts — HMRC may request evidence for large or irregular donations.
Strategic Use for High Earners
For additional‑rate taxpayers, charitable giving can be part of a structured annual tax plan. Many professionals set donation targets each tax year to maintain adjusted net income within optimal ranges. Combining Gift Aid with pension contributions compounds the effect, often restoring the full personal allowance while supporting social causes.
Tip: Charitable foundations or donor‑advised funds (DAFs) provide an advanced approach for philanthropists. You can contribute a lump sum in one tax year for immediate relief, then distribute grants gradually over time.
Broader Benefits
Beyond tax savings, strategic philanthropy reinforces personal values and corporate reputation. Many London firms encourage directors to participate in matching‑gift programmes, effectively doubling the impact. For individuals, donating publicly but tastefully can also enhance brand perception and credibility.
The Takeaway
Gift Aid exemplifies how doing good can coincide with sound financial strategy. By timing donations, carrying back reliefs, and integrating charitable giving into broader tax planning, additional‑rate earners can achieve both social impact and fiscal efficiency. For London’s elite professionals, generosity is not just virtuous — it’s financially intelligent.
Investment Reliefs — EIS, SEIS, and VCTs
For additional-rate earners, investment reliefs such as EIS, SEIS, and VCTs can unlock some of the most potent tax advantages available under UK law. These government-endorsed schemes channel private capital into small and growing British businesses, fuelling innovation while rewarding investors with significant tax reliefs. For London-based professionals seeking to diversify their portfolios and optimise tax outcomes, these schemes combine enterprise support with exceptional fiscal benefits.
The Strategic Role of Investment Reliefs
London’s high earners often face a dilemma: traditional savings and bonds offer low yields after tax, while direct property investments face heavy stamp duty and capital gains exposure. EIS, SEIS, and VCTs bridge this gap by offering generous upfront reliefs and post-exit advantages, enabling sophisticated investors to achieve both impact and efficiency.
Understanding the Core Schemes
| Scheme | Income Tax Relief | CGT Benefits | Investment Limit | Key Features |
| EIS (Enterprise Investment Scheme) | 30% on up to £1m (£2m for knowledge-intensive companies) | CGT deferral and exemption after 3 years; IHT relief after 2 years | £1m / £2m | Ideal for scale-ups; risk mitigated via diversification |
| SEIS (Seed Enterprise Investment Scheme) | 50% on up to £200,000 | 50% CGT reinvestment relief; CGT-free growth | £200k | Suited to very early-stage companies; highest risk, highest potential |
| VCT (Venture Capital Trust) | 30% on up to £200,000 | Tax-free dividends and CGT-free disposal | £200k | Publicly listed funds providing managed exposure to smaller companies |
How the Reliefs Interact with Income and Capital Gains
EIS: Investors receive 30% Income Tax relief in the year of investment or can carry back to the previous year. If shares are held for at least three years, any capital gain on disposal is tax-free. Previous gains can also be deferred by reinvesting them into qualifying EIS shares.
SEIS: Offers the highest upfront relief — 50% Income Tax reduction — making it attractive for additional-rate taxpayers. Gains from other disposals reinvested into SEIS shares qualify for a 50% CGT exemption.
VCT: Although the upfront relief is similar to EIS, VCTs pay tax-free dividends, a unique advantage for investors seeking recurring income. These can serve as a quasi-pension stream, particularly relevant for those maxing out pension allowances.
Real-World Illustration
A Canary Wharf executive invests £100,000 into an EIS-qualifying tech start-up.
Income Tax relief: £30,000
Potential CGT deferral on previous share sale: £15,000 saved
If held for three years, gain on disposal: 0% CGT
Net effective cost: £55,000 for a £100,000 investment with significant upside potential.
Alternatively, investing £100,000 into a VCT yields £30,000 immediate tax relief and provides access to tax-free dividends averaging 5–7% annually — an efficient complement to a pension portfolio.
Advanced Planning Opportunities
Pairing with Pension or Gift Aid Reliefs: Combine investment reliefs with pension contributions or charitable donations to manage adjusted net income efficiently.
Deferral of Large Capital Gains: EIS allows deferral of gains from asset disposals (including property) within 36 months before or after the investment.
Inheritance Tax Planning: EIS and SEIS shares qualify for Business Relief after two years, potentially exempting them from IHT.
Portfolio Diversification: While high-risk individually, investing across 10–20 qualifying companies through a managed EIS or VCT fund can reduce exposure while maintaining tax efficiency.
Corporate Executives and Founders: Directors can invest via their companies where aligned with HMRC guidelines, but professional advice is essential.
Risks and Compliance Considerations
Illiquidity: Most EIS and SEIS shares cannot be sold easily; investors should be prepared for a 3–5-year hold.
Capital at Risk: Reliefs mitigate losses but do not guarantee success; due diligence is essential.
Scheme Qualification: Always verify that the investment is approved by HMRC before subscribing — retrospective approvals are not guaranteed.
Record-Keeping: Investors must retain the EIS3 or SEIS3 certificate to claim relief. Missing documentation can delay or invalidate relief.
Strategic Takeaway
EIS, SEIS, and VCTs occupy a unique space between philanthropy, venture capital, and structured tax planning. They enable London’s additional-rate earners to channel funds into innovation while accessing elite-level tax benefits — from upfront relief to long-term exemption and inheritance mitigation. Managed intelligently, these vehicles become more than just tax shelters: they are engines of enterprise growth and personal wealth evolution.
| EIS (Enterprise Investment Scheme) | 30% relief up to £1m (£2m for knowledge‑intensive) | CGT deferral, IHT relief after 2 years | Higher risk, longer hold | | SEIS (Seed EIS) | 50% relief up to £200k | CGT exemption | Early‑stage firms | | VCT (Venture Capital Trust) | 30% relief up to £200k | Tax‑free dividends, CGT‑free exit | Publicly listed funds |
Example: £100,000 invested in EIS → £30,000 tax relief + potential CGT deferral + IHT exemption after 2 years.

Capital Gains Planning
Strategic Capital Gains Planning for London Residents
Capital gains planning is essential for London residents seeking to maximise tax efficiency. Our team at CIGMA Accounting will create a customised plan that reflects the unique property and investment landscape of London, Wimbledon, Fulham Broadway and Farringdon.
Local Insight: Capital Gains in Wimbledon
For residents in Wimbledon, where property values can fluctuate, our experts offer insights into optimising Capital Gains Tax through informed property transactions and investment decisions.
Capital Gains Tax (CGT) is one of the most significant yet misunderstood areas of personal taxation for London’s high earners. Whether selling property, shares, or business assets, understanding how to manage and defer gains can make a measurable difference to your post-tax wealth. The CGT regime, though relatively simple in rates, offers a variety of reliefs and timing opportunities that can dramatically reduce liabilities when used strategically.
Overview of CGT Rates and Allowances
The CGT annual exemption has been reduced to just £3,000 for the 2025/26 tax year, tightening the margin for tax-free disposals. Above this threshold, the applicable rates are:
| Asset Type | Basic / Higher / Additional | CGT Rate 2025/26 |
| Residential Property | 18% / 28% | 28% |
| Other Assets (shares, crypto, business assets) | 10% / 20% | 20% |
These rates apply after deducting the annual exemption and allowable losses. For London investors, particularly those with property and equity portfolios, proactive planning can prevent unnecessary exposure to the top CGT rate.
Strategic Use of the Annual Exemption
Although £3,000 may seem modest, allocating it annually across assets and spouses can lead to long-term efficiency. Married couples or civil partners can transfer assets between each other tax-free, effectively doubling the exemption to £6,000. Strategic use of both partners’ basic-rate bands can also reduce the effective rate on gains from 20% to 10%.
Tip: Plan disposals over multiple tax years to maximise annual allowances and avoid large one-off gains.
Leveraging Losses and Offsetting
Capital losses can be used to offset gains in the same tax year or carried forward indefinitely to future years. Recording and reporting losses promptly ensures they remain available for future offset. London investors often forget to declare small share or crypto losses, inadvertently paying tax they could have legally avoided.
Example:
A Chelsea investor makes £50,000 of gains and £20,000 of losses in the same year. Only the net £30,000 is taxable. At 20%, the liability is £6,000 instead of £10,000.
Using EIS and SEIS to Defer or Eliminate CGT
Reinvesting gains into EIS or SEIS shares allows for full or partial deferral of CGT. The deferred gain only crystallises when the investment is sold, providing both time and liquidity advantages. After three years, qualifying EIS shares become CGT-free upon disposal.
Illustration:
A Farringdon executive realises a £200,000 gain from listed shares. By reinvesting £150,000 into an EIS fund, they immediately defer CGT on that portion and also claim £45,000 in Income Tax relief. If held for three years, the reinvested gain is permanently exempt from CGT.
Asset Structuring for Property Owners
London property investors, particularly landlords, face the 28% residential CGT rate. Reliefs and planning opportunities include:
Principal Private Residence (PPR) Relief: Applies to your main home, but not investment properties. If you’ve lived in a property at any point, a portion of the gain may qualify for exemption.
Lettings Relief: Limited but still available in certain shared-occupancy cases.
Joint Ownership Transfers: Spousal transfers before sale allow better use of both allowances and rate bands.
Timing of Sale: Completing before April 6th may shift gains into a more favourable year, depending on other income.
Incorporation Relief: For landlords running an actual property business (multiple properties, active management), transferring to a company can defer CGT until shares are sold.
Business Asset Disposal Relief (BADR)
Previously known as Entrepreneurs’ Relief, BADR offers a 10% CGT rate on qualifying business disposals up to £1 million lifetime limit. Qualifying conditions include holding at least 5% of shares and being an officer or employee of the company for two years before sale. For London entrepreneurs selling limited company shares, this remains a powerful exit tool when combined with EIS deferral or pension planning.
Optimising Timing and Income Interaction
Because CGT and Income Tax operate on separate but related systems, it’s possible to reduce overall exposure by managing when gains are realised. Deferring a disposal into a lower-income year or spreading sales across multiple tax years allows better use of lower-rate bands and exemptions.
Key Takeaways
Use your £3,000 annual exemption and double it with spousal transfers.
Harvest and record losses — they can save tax for years to come.
Reinvest gains into EIS/SEIS for deferral or elimination.
Time property and asset sales around fiscal year boundaries.
For business owners, explore BADR before restructuring or sale.
Strategic Insight
Capital Gains Tax planning requires foresight, not reaction. In London’s fast-moving property and financial markets, a single unplanned disposal can create a liability of tens of thousands. With professional timing, diversification, and relief utilisation, high earners can transform CGT from a burden into a tool for long-term portfolio optimisation and intergenerational wealth transfer. | Residential Property | 18% / 28% | 28% | | Other Assets | 10% / 20% | 20% |
Smart CGT Planning Moves
Use your £3,000 annual exemption before April 2026.
Transfer assets to a spouse to double exemptions.
Crystallise losses to offset future gains.
Defer gains via EIS reinvestment.
Case Example: A Farringdon executive sells a £200,000 gain in shares. By reinvesting £150,000 into EIS, they defer CGT and reduce income tax liability by £45,000.
Managing International & Non‑Dom Income
London’s global status attracts thousands of professionals and entrepreneurs each year who maintain income, assets, or business interests abroad. For additional‑rate earners, the intersection between UK and international tax systems offers both complexity and opportunity. Understanding residency rules, foreign tax credits, and the upcoming 2025 non‑dom reforms is essential for optimising your position while remaining fully compliant.
The Evolving Landscape: From Non‑Dom to FIG
Historically, the UK’s non‑domiciled (non‑dom) regime allowed foreign nationals to exclude overseas income and gains from UK tax, provided they did not remit the funds to the UK. This system is being phased out in April 2025, replaced by the new Foreign Income and Gains (FIG) regime.
Under the FIG system:
New residents who have been non‑UK residents for the previous 10 years can enjoy four years of full exemption on foreign income and gains.
During this period, funds can be brought to the UK without triggering tax, creating a powerful planning window.
After four years, worldwide income and gains become taxable as normal UK residents.
This change simplifies but also limits long‑term planning opportunities. High earners arriving in London will need to plan carefully to take advantage of this initial relief period.
Practical Implications for London Residents
Timing Matters: New arrivals should consider accelerating dividends, interest, or capital gains during their four‑year FIG window.
Segregation of Funds: Keep pre‑arrival income and post‑arrival income separate to prevent inadvertent remittances that could trigger UK tax.
Estate and Trust Structures: Review offshore trusts and companies; distributions after April 2025 may be treated differently.
Transition Planning for Existing Non‑Doms: Individuals under the old regime must assess the benefit of rebasing or realising foreign gains before the regime changes.
Example:
An Italian entrepreneur relocating to Mayfair in 2025 who has been a non‑UK resident for over a decade can claim FIG status. For the first four tax years, they can receive foreign dividends, rent, and investment gains tax‑free in the UK, even if remitted to a UK account.
Double Tax Treaties and Foreign Tax Credits
The UK has one of the most extensive double tax treaty networks in the world, covering over 130 jurisdictions. These treaties prevent the same income from being taxed twice and determine which country has primary taxing rights.
For London professionals with cross‑border roles — such as consultants working partly in the EU or executives paid by multinational groups — proper application of treaty provisions ensures relief from double taxation. When foreign taxes are paid, the Foreign Tax Credit Relief mechanism allows these amounts to offset UK tax due on the same income.
Tip: Always retain detailed evidence of taxes paid abroad, including local tax returns and withholding certificates, to support credit claims with HMRC.
Managing Exchange Rates and Timing of Remittances
Exchange rate fluctuations can significantly affect reported gains and income. HMRC requires conversions into GBP on the date income is received or remitted, which can create unexpected taxable profits or losses. Planning remittances during favourable currency conditions can reduce exposure.
For existing non‑doms transitioning into the FIG regime, repatriating funds before April 2025 may be advantageous, as post‑reform remittances will likely lose their favourable treatment.
Property and Investment Considerations
Many high earners own overseas property or investment portfolios. Rental income from foreign properties is generally taxable in both jurisdictions, but treaties typically grant credit relief. Foreign property expenses — such as mortgage interest and maintenance — remain deductible if wholly and exclusively incurred for generating that income. Similarly, foreign investments must be reported annually under UK worldwide disclosure (WDF) rules.
Residency and Split‑Year Treatment
Determining whether you are a UK resident is governed by the Statutory Residence Test (SRT), which considers time spent in the UK, ties such as accommodation or work, and previous residency history. In your first or last year of UK residence, split‑year treatment may apply, dividing the year into UK and non‑UK periods, helping to avoid double taxation.
Strategic Recommendations for 2025–26
Review non‑dom status immediately: Identify whether you qualify for FIG relief and how long it lasts.
Rebase or realise foreign gains pre‑April 2025: Lock in favourable treatment before the new regime.
Track days under SRT carefully: Exceeding thresholds may trigger UK residency earlier than intended.
Consider professional structuring: Trusts, corporate wrappers, or offshore bonds may still provide compliant long‑term benefits.
Strategic Takeaway
International income management is one of the most sophisticated areas of tax planning. The 2025 reforms mark a pivotal shift for London’s globally mobile elite. With careful planning — from timing remittances and segregating accounts to leveraging treaty protection — additional‑rate earners can remain compliant while preserving international flexibility. In an era of increasing transparency and tightening HMRC scrutiny, precision and proactive advice are paramount.

The Power of Timing — Avoiding the 62% Trap
For additional‑rate earners, when income arises often matters as much as how much arises. The steep withdrawal of the personal allowance between £100,000–£125,140 means that poorly timed bonuses, dividends, or option exercises can be taxed at an effective 60%+ marginal rate (before NI). By contrast, deft timing can legally pull income back into lower bands, restore allowances, and unlock reliefs that would otherwise be lost.
Core Timing Levers
Bonuses (PAYE income): To potentially reduce your tax liability, consider requesting payment after April 6th to move a bonus into the next tax year if you anticipate a lower income at that time (for instance, during a sabbatical, career change, or parental leave). Additionally, directors should consider the mechanics of the annual earnings period for National Insurance when timing awards. Additionally, directors should consider the mechanics of the annual earnings period for National Insurance when timing awards.
Dividends: Split payments across two tax years to keep more within the basic/higher bands and within the small remaining dividend allowance. Coordinate with a spouse/civil partner to use their bands.
Pension Contributions: Make or increase contributions before 5 April to reduce adjusted net income now; use carry‑forward to mop up unused allowances from the prior three years.
Gift Aid Donations: Donate before 31 January and consider the carry‑back election to apply donations to the prior tax year if that delivers higher‑rate relief.
Capital Gains: Stage disposals over two tax years, crystallise losses in high‑gain years, and consider EIS/SEIS reinvestment to defer/eliminate CGT.
Share Options / Equity (EMI, CSOP, RSU): Model exercise/vesting dates; exercising just after 6 April can provide an extra year to plan the resulting income or gains. For EMI, early exercise before a value uplift may lock in more growth at CGT rates.
Two London‑Focused Scenarios
Scenario A — Canary Wharf bonus:
A VP earning £118,000 expects a £20,000 bonus in March. If paid in March, their adjusted net income reaches £138,000, thereby maximising personal allowance withdrawal and exposing a significant portion of the bonus to the ~62% marginal band. By deferring the bonus to April and making a £12,000 pension contribution in March, they finish the old tax year below £100,000 (restoring the allowance) and start the new year with room to plan the April bonus using fresh bands.
Scenario B — Wimbledon consultant dividends:
A consultant drawing dividends from their company expects £50,000 of retained profits to distribute. Paying £25,000 in March and £25,000 in May allows use of two sets of allowances and avoids breaching the additional‑rate threshold in a single year. Spousal shareholdings let £10,000 fall into the partner’s lower bands, reducing overall dividend tax.
Practical Timeline (What to Check and When)
September–December: Forecast total income/gains. Identify if you’ll land in the £100k–£125,140 band. Decide whether to accelerate (e.g., donations) or defer (e.g., dividends/bonus). Start paperwork for salary sacrifice changes.
January–March: Execute pension top‑ups (use carry‑forward), make Gift Aid donations (with carry‑back option), harvest losses, and schedule equity exercises. Finalise year‑end dividend amounts to avoid tipping into the 45% band.
April–June: If you deferred income, reassess bands with the new year’s figures; re‑sequence payouts. Consider early‑year pension contributions to smooth cashflow and keep adjusted income on track.
Coordination Tips
Spouse/Civil Partner Planning: Transfer shares before dividend declarations, and shift assets before CGT disposals to use two allowances/bands.
Company Directors: Align board minutes, dividend vouchers, and payment dates with your tax plan. Document intent — HMRC values contemporaneous records.
Cashflow vs. Tax: Ensure deferrals don’t create liquidity stress; consider bridging via company cash or drawings within safe limits.
Watch‑Outs
Substance over form: HMRC may challenge artificial deferrals without a commercial rationale. Ensure timing decisions have a genuine business or personal income‑smoothing purpose.
Benefits interactions: Salary sacrifice or lower salary can affect mortgage affordability, life cover multiples, and statutory payments.
Equity pitfalls: Option window rules, disqualifying events (for EMI), and employer compliance (reporting on ERS) must be checked before changing exercise dates.
The Takeaway
Timing is a precision tool, not a gimmick. By planning bonuses, dividends, pension input, donations, and disposals around tax‑year boundaries — and by coordinating with partners and your company — London high earners can sidestep the 62% trap, preserve allowances, and materially lower lifetime tax drag without straying beyond mainstream, HMRC‑aligned practice.
Common Mistakes Additional‑Rate Earners Make
| Mistake | Impact | Prevention |
| Ignoring pension carry‑forward | Missed tax relief worth thousands | Annual review with the accountant |
| Overlooking Gift Aid carry‑back | Loss of potential refund | Plan donations before 31 Jan |
| Triggering annual allowance taper | Pension overpayment charge | Check adjusted income limits |
| Mis‑timing dividend payments | Pushing into the 45% band | Align with personal allowance bands |
| Neglecting EIS/VCT | Missing 30% tax relief | Annual tax‑efficient investment review |
FAQs — Quick Answers for London High Earners
Yes — they reduce your adjusted net income, potentially restoring your personal allowance
It occurs between £100,000–£125,140 due to loss of personal allowance, raising the effective tax rate to 60%+.
Yes — it saves both income tax and NI. Employers also save NI, often reinvesting it into your pension
EIS targets direct investments in private firms (higher risk), while VCTs are managed funds offering diversification
Yes, under double tax treaties or via the foreign tax credit system — depending on residency status.
Stay within compliant, mainstream reliefs (pensions, EIS, Gift Aid) and avoid marketed tax avoidance schemes.
Benefit‑in‑Kind (BiK) rates on electric vehicles remain at 2% until 2025 — far lower than petrol equivalents (~30%). When combined with salary sacrifice, EVs save 40–60% versus purchasing privately.
Yes, under the new Foreign Income & Gains (FIG) regime. New arrivals enjoy four years of tax‑free foreign income if non‑resident for the previous ten years. Existing non‑doms should realise or rebase foreign gains before April 2025.
Use spousal transfers, annual exemptions (£3,000 each), and EIS reinvestment to defer or eliminate gains. Selling across tax years can further reduce exposure. Property incorporation may defer CGT for landlords running active property businesses.
Plan flexibly. In high‑income years, prioritise pension top‑ups and donations. In lower‑income years, realise gains or dividends to utilise unused bands. Annual forecasting, each December–February, ensures optimal alignment.
