Tax Planning UK: Pre-Tax Year-End Planning for Individuals and Businesses

What Is Tax Planning?

Tax planning is the process of reviewing financial decisions before they become fixed for tax purposes. The aim is to understand when income and gains will arise, which reliefs are available, and whether planned expenditure or contributions should be made before or after the year end.

A year-end review may cover:

• Income Tax bands and the Personal Allowance
• Pension contributions
• Gift Aid donations
• Dividends and salary extraction
• Capital Gains Tax disposals and losses
• ISA subscriptions
• Capital allowances
• Corporation Tax profits
• Stock, bad debts and provisions
• Director remuneration
• Family income planning
• Inheritance Tax gifting

Why Timing Matters in Tax Planning UK

The UK tax system is highly sensitive to timing. Income received on 4 April may fall into a different tax year from income received on 6 April. A company asset purchased before the accounting year end may accelerate Corporation Tax relief, while the same purchase made afterwards may defer relief for another year.

Timing can affect:

• The Income Tax rate applied to income
• Whether the Personal Allowance is preserved
• Whether annual pension allowances are used
• Whether the Capital Gains Tax annual exemption is available
• When capital allowances reduce taxable profit
• Whether dividend income falls into one tax year or the next
• When tax becomes payable

Tax should never be the only commercial consideration, but the timing of an otherwise sensible transaction can materially affect cash flow.

Key 2026/27 Tax Planning Figures

Thresholds and reliefs can depend on income, prior contributions, residence, business structure and other circumstances. A personalised calculation is therefore important.

Personal Tax Planning Before 5 April 2027

Personal tax planning should begin with a forecast of total taxable income for the year. Include salary, bonuses, dividends, self-employed profits, rental income, savings interest, pensions and taxable benefits.

The forecast should identify whether income is close to:

• The basic-rate limit
• The £100,000 Personal Allowance taper
• The £125,140 additional-rate threshold
• The High Income Child Benefit Charge range
• The pension annual allowance taper thresholds

Protecting the Personal Allowance

The £12,570 Personal Allowance is reduced by £1 for every £2 of adjusted net income above £100,000. It is fully withdrawn at £125,140.

This creates an effective 60% marginal Income Tax rate on relevant earned income in the taper band for taxpayers in England, Wales and Northern Ireland. Pension contributions and Gift Aid donations can reduce adjusted net income where the rules are satisfied.

Pension Contributions

Pension contributions are one of the main year-end planning tools. They may:

• Generate Income Tax relief
• Reduce adjusted net income
• Help preserve the Personal Allowance
• Reduce exposure to the High Income Child Benefit Charge
• Move income out of higher or additional tax bands

The standard annual allowance is £60,000 for 2026/27, but lower limits can apply where the tapered annual allowance or money purchase annual allowance is relevant. Employer and personal contributions both count towards the available allowance.

Unused allowance from the previous three tax years may be carried forward if the conditions are met, but the individual must generally have been a member of a registered pension scheme in those years.

Gift Aid Donations

Gift Aid can extend the basic-rate band and reduce adjusted net income. A net donation of £800 is treated as a gross donation of £1,000 for these calculations.

The donor must have paid enough UK Income Tax or Capital Gains Tax to cover the amount reclaimed by the charity. Donations should not be made solely for tax reasons, but planned charitable giving may be more effective when completed before 5 April.

Tax Planning for Higher-Rate and Additional-Rate Taxpayers

Higher earners can face several overlapping tax effects. A small increase in income may lead to a higher tax rate, loss of the Personal Allowance, additional dividend tax or a pension annual allowance restriction.

A year-end review should consider:

• Deferring or accelerating bonuses where commercially possible
• Increasing pension contributions within available limits
• Making planned Gift Aid donations
• Reviewing taxable benefits
• Managing dividend timing
• Using ISA allowances
• Reviewing capital gains and losses

High Income Child Benefit Charge Planning

The High Income Child Benefit Charge is based on adjusted net income. Pension contributions and Gift Aid may reduce the relevant figure.

Families should review:

• Which partner has the higher adjusted net income
• Expected bonuses and dividends
• Pension contributions already made
• Whether Child Benefit should continue to be claimed for National Insurance credits

Capital Gains Tax Planning Before Year End

The individual Capital Gains Tax annual exempt amount is £3,000 for 2026/27. Because the exemption cannot normally be carried forward, planned disposals should be reviewed before 5 April.

Use the Annual Exemption Carefully

Taxpayers may consider realising gains within the annual exempt amount, but transaction costs, investment strategy and anti-avoidance rules must be considered.

Use Capital Losses

Capital losses may offset gains. Losses must be valid, correctly claimed and used in the required order. Negligible-value claims may also be relevant where an investment has become worthless or of negligible value.

Transfers Between Spouses and Civil Partners

Transfers between spouses and civil partners living together are generally made on a no-gain, no-loss basis. This can help use both annual exemptions and tax bands, but ownership must genuinely transfer before disposal.

Watch the 60-Day Property Reporting Deadline

UK residential property gains may need to be reported and paid within 60 days of completion. Year-end planning does not remove this separate reporting obligation.

ISA and Investment Planning

ISA allowances operate on a use-it-or-lose-it basis. A contribution must be made by 5 April to use the allowance for that tax year.

Before investing, consider:

• Investment risk
• Access requirements
• Fees
• Diversification
• Whether pension contributions are more suitable

Dividend Planning for 2026/27

The dividend allowance remains £500, while the ordinary and upper dividend rates increased from 6 April 2026 to 10.75% and 35.75%. The additional rate remains 39.35%.

Owner-managed companies should not decide dividends by tax rate alone. A valid dividend requires sufficient distributable reserves, proper board approval and accurate documentation.

Questions for year-end review include:

• Does the company have sufficient distributable profit?
• Would a dividend move the shareholder into a higher band?
• Would it reduce the Personal Allowance?
• Would an employer pension contribution be more appropriate?
• Is cash needed personally now?

Tax Planning for Owner-Managed Businesses

Owner-managed businesses should review company profits, personal income and cash needs together. Salary, dividends, pension contributions and benefits have different Income Tax, National Insurance and Corporation Tax consequences.

Salary and Bonus Timing

A salary or bonus may reduce company profits if it is incurred wholly and exclusively for the trade and paid within the relevant rules. However, PAYE and National Insurance costs must be considered.

Employer Pension Contributions

Employer pension contributions can be Corporation Tax deductible where they are incurred wholly and exclusively for the trade. Relief generally follows the accounting period in which the contribution is actually paid, not merely accrued.

Director Loan Accounts

Overdrawn director loan accounts should be reviewed before the company year end and before the nine-month Corporation Tax payment deadline. Section 455 tax and benefit-in-kind consequences may arise.

Capital Allowances and Investment Timing

Businesses planning to buy plant, machinery, equipment or commercial vehicles should review whether completing the purchase before year end accelerates tax relief.

Annual Investment Allowance

The Annual Investment Allowance permits qualifying businesses to deduct up to £1 million of qualifying plant and machinery expenditure. The available limit may need to be shared between connected businesses.

Full Expensing

Companies can claim 100% full expensing on qualifying new and unused main-rate plant and machinery. A 50% first-year allowance may apply to qualifying new special-rate assets. Cars are excluded.

Electric Cars

New and unused zero-emission cars may qualify for a 100% first-year allowance, subject to the applicable conditions. Benefit-in-kind and charging arrangements should also be reviewed.

Stock, Bad Debts and Provisions

Year-end accounts should not overstate profit because records were not reviewed properly. Businesses should examine:

• Slow-moving and obsolete stock
• Specific bad debts
• Accrued expenditure
• Prepayments
• Work in progress
• Warranty or other provisions

General reserves created solely to reduce tax are not normally deductible. Adjustments must reflect proper accounting treatment and tax law.

Corporation Tax Rate Planning

Companies should forecast taxable profit before year end, including associated-company effects. The main Corporation Tax rate is 25%, with a 19% small-profits rate and marginal relief between the relevant limits.

The £50,000 and £250,000 profit thresholds are reduced where companies have associated companies and for short accounting periods. Group structures should therefore be reviewed carefully.

Loss Planning

Businesses expecting a loss should consider how and when it can be used. Depending on the circumstances, losses may be carried forward, carried back or surrendered within a qualifying group.

The timing of expenditure and income can affect the period in which the loss arises and the speed of tax relief.

VAT and Year-End Checks

VAT planning should focus on correct treatment rather than merely delaying payment. Review:

• Registration and deregistration thresholds
• Bad debt relief
• Partial exemption
• Capital Goods Scheme adjustments
• Input tax evidence
• Reverse charge transactions
• Business and private use

Tax Planning for Sole Traders

Sole traders should forecast taxable profit before 5 April and review:

• Allowable expenses
• Capital purchases
• Stock and work in progress
• Bad debts
• Pension contributions
• Payments on account
• Making Tax Digital obligations

If the forecast reveals a bill that’s likely to be difficult to pay in full, it’s worth exploring in advance how to set up a Self Assessment payment plan with HMRC rather than waiting until the deadline arrives. Even a partial payment made in advance, such as by paying tax by credit or debit card, can reduce the balance on which interest accrues while a longer-term plan is arranged.

From April 2026, qualifying sole traders and landlords with gross income over the applicable threshold may need to comply with Making Tax Digital for Income Tax.

Tax Planning for Landlords

Landlords should review rental income, allowable property costs, finance-cost relief, repairs, capital improvements and planned disposals.

Key questions include:

• Are repairs revenue expenses or capital improvements?
• Have all agent fees, insurance and service charges been captured?
• Is any property sale likely before or after 5 April?
• Will a disposal trigger the 60-day CGT reporting requirement?
• Does MTD for Income Tax apply from April 2026 or 2027?

Inheritance Tax and Lifetime Gifting

Some Inheritance Tax exemptions operate annually. Individuals considering gifts should review the annual exemption, small-gift exemption, normal expenditure out of income and gifts on marriage or civil partnership.

Gifts must be genuine, documented and affordable. Estate planning should also consider Capital Gains Tax, control, access to funds and the seven-year rule.

Tax Planning Advice for Families

Family planning may involve the ownership of savings, investments or business shares. Transfers must be genuine, and anti-avoidance rules can apply.

A review might include:

• Use of both spouses’ or civil partners’ allowances
• Ownership of income-producing assets
• Pension funding for non-working spouses
• Junior ISAs and pensions for children
• Family company share structures

Tax Planning Mistakes to Avoid

• Waiting until after 5 April
• Making pension contributions without checking annual allowance limits
• Paying dividends without distributable reserves
• Buying assets solely for tax relief
• Confusing repairs with capital improvements
• Ignoring associated-company rules
• Assuming all year-end provisions are deductible
• Failing to document spouse transfers
• Overlooking cash-flow and payment deadlines
• Using outdated tax rates

Even with careful planning, circumstances can still change unexpectedly knowing in advance what to do if you cannot pay your tax on time means you’re not starting from scratch if that happens.

A year-end review can also be a good moment to check whether an earlier overpayment was ever recovered, since claiming a tax refund is subject to its own time limits that shouldn’t be left unchecked.

Pre-Year-End Tax Planning Checklist

1. Forecast total personal and business income.
2. Identify tax-band and allowance thresholds.
3. Review pension contributions and carry forward.
4. Consider planned Gift Aid donations.
5. Review capital gains and losses.
6. Use ISA allowances where appropriate.
7. Check salary and dividend extraction.
8. Review employer pension contributions.
9. Plan qualifying capital expenditure.
10. Review stock, bad debts and provisions.
11. Check director loan accounts.
12. Forecast tax payments and cash flow.

Once your forecast is in place, using the HMRC app to make Self Assessment tax payments can make it easier to stay on top of instalments as the year progresses rather than waiting for a single year-end payment.

If a bill has already gone unpaid for some time rather than being a fresh concern, a broader review of the options for help with outstanding tax bills may be more relevant than routine year-end planning alone.

When to Speak to a Tax Planning Advisor

A tax planning advisor can help where income is close to a threshold, several income sources interact, a company is planning dividends or investment, or a significant disposal is expected.

Advice is especially useful where:

• Adjusted net income may exceed £100,000
• Pension tapering may apply
• A business has associated companies
• A property or share disposal is planned
• A director loan account is overdrawn
• International income or residence issues arise
• Inheritance Tax planning is required

Final Tax Planning UK Review Before Year End

Effective tax planning UK starts with accurate figures and enough time to act. Individuals should review income, pensions, Gift Aid, investments and capital gains before 5 April 2027, while businesses should examine profit extraction, capital expenditure, provisions and company tax before their accounting year end.

The right decision is not always the one that produces the largest immediate deduction. A good plan balances tax efficiency, cash flow, investment risk, commercial needs and long-term goals. Where cash flow is genuinely tight despite good planning, spreading tax payments by using Time to Pay remains a legitimate option rather than something to be avoided out of concern.

Tax Planning Case Study

Sarah, the director of a growing consultancy business, visited our Farringdon office a few months before the end of the tax year. With income from her company, dividends and personal investments, she wanted to review her position through tax planning UK to ensure she wasn’t missing legitimate reliefs before the 5 April deadline.

During our review, we forecast Sarah’s personal and company income, examined her dividend strategy, assessed pension contribution opportunities and checked whether any planned capital expenditure should be brought forward before her company’s year end. We also reviewed her ISA allowance, potential Capital Gains Tax implications and the impact that higher income could have on her Personal Allowance. By considering each area together, we identified several legitimate planning opportunities that could improve cash flow while remaining fully compliant with HMRC rules.

We also discussed the importance of acting before key deadlines rather than after the tax year had ended, when many allowances and planning opportunities are no longer available. This gave Sarah time to make informed decisions instead of rushing them at the last minute.

By the end of the consultation, Sarah had a clear year-end tax strategy, confidence that she was making the most of available reliefs and a practical plan for both her personal and business tax affairs.
