Company Directors: Mandatory Self-Assessment Reporting Rules from April 2025
As of April 2025, company directors of close companies and self-employed taxpayers face new, mandatory reporting requirements under HMRC’s updated Self-Assessment rules. This marks one of the most significant changes to director compliance in recent years, impacting around 900,000 company directors and 1.2 million traders across the UK.
At CIGMA Accounting, with offices in Wimbledon, Farringdon, Sutton, and Canary Wharf, we’re helping business leaders and directors prepare early. Here’s everything you need to know to stay compliant — and avoid unnecessary penalties.
The April 2025 Shift: Why This Matters Now
The 2025 reforms represent a defining moment for directors and self-employed taxpayers. For years, Self Assessment relied heavily on voluntary disclosure, meaning that many directors could overlook minor details about dividends or ownership without facing immediate consequences. However, the introduction of mandatory reporting from April 2025 changes that landscape entirely. Now, HMRC expects every director to proactively disclose comprehensive information about their role, shareholdings, and trading activity.
The rationale behind this shift is clear: HMRC seeks to close the gap between corporate and personal reporting, ensuring all income streams and ownership structures are transparent. This helps identify potential tax discrepancies early — particularly within close companies where ownership is concentrated among a few individuals. The reform also complements broader initiatives, such as Making Tax Digital (MTD) and the OECD’s DAC7 data exchange, reflecting a global push for financial transparency.
Directors will now need to maintain detailed, up-to-date digital records. The margin for error or late disclosure is shrinking fast, as HMRC’s systems cross-check Self Assessment entries with Companies House filings, bank transaction data, and even accounting software integrations. A mismatch between declared income and what appears in these systems can automatically flag your return for review.
For example, a director who receives dividends in March 2026 but forgets to declare them in their 2025–26 Self Assessment could trigger an HMRC query — especially if those same dividends appear in company records or banking data. Similarly, inconsistencies between payroll data, dividend vouchers, and shareholder reports will now be far easier for HMRC to detect.
In practical terms, this means directors must collaborate closely with their accountants throughout the year, not just at year-end. Ongoing bookkeeping, quarterly reviews, and pre-year-end reconciliation will become essential compliance practices.
For business owners, this reform isn’t just about meeting obligations — it’s also an opportunity to strengthen internal governance. Those who implement accurate digital systems will gain more apparent financial oversight, improved investor confidence, and faster access to data-driven insights.
At CIGMA Accounting, we’ve been preparing clients for this shift for months. Our specialists are helping directors automate compliance tasks using Xero, QuickBooks, and Zoho Books, ensuring real-time visibility and data integrity. By bridging accounting software with HMRC’s evolving systems, we’re not just reducing administrative pressure — we’re helping businesses future-proof their compliance strategies.

What is a Close Company?
A close company is typically defined as a limited company controlled by five or fewer individual shareholders, or by any number of directors. In practice, this definition applies to the majority of private limited companies in the UK, including family-owned firms, professional partnerships, and smaller businesses where ownership is concentrated. The classification is essential because HMRC uses it to identify potential areas of profit extraction or tax avoidance.
The idea behind the “close company” rules is to ensure fairness and transparency. When control lies with a small group, HMRC assumes there is a higher risk that funds may be taken out of the company as untaxed loans or informal dividends. Therefore, from April 2025, directors of close companies are required to disclose more detailed information about their roles, shareholdings, and distributions to help HMRC verify that all income is reported accurately.
This includes:
- Confirming whether they are directors of a close company.
- Providing the company’s name, registration number, and details of shareholdings.
- Reporting dividends or other distributions received during the tax year.
- Declaring the highest percentage of shares held if ownership changes during the year.
To illustrate, consider a small marketing agency owned by three directors and two minority shareholders. Previously, each director may have reported dividends informally through their accountant. Under the new system, each director must explicitly confirm their shareholding and dividend amounts within their personal Self Assessment, creating a clear data match with the company’s records at Companies House and HMRC’s digital systems.
The implications are far-reaching. Directors can no longer rely on informal dividend tracking or manual spreadsheets to manage their investments. Instead, they must maintain robust digital bookkeeping, ideally through cloud platforms such as Xero or QuickBooks, which automatically record shareholder payouts and produce digital dividend vouchers.
Additionally, these changes will make it easier for HMRC to detect discrepancies between declared personal income and company profits. If the company’s retained earnings are unusually low but the directors’ reported income is minimal, HMRC may investigate whether funds were withdrawn as loans rather than dividends.
Directors of close companies should therefore review how they extract profits and ensure that every transaction — whether it is a salary, dividend, or loan — is properly documented. Companies should also update shareholder agreements to align with the new reporting obligations.
At CIGMA Accounting, we help close-company directors implement transparent systems that simplify compliance. Our team integrates your payroll, bookkeeping, and dividend processes so everything aligns with HMRC’s 2025 standards.

The New Mandatory Reporting Requirements
The 2025–26 tax year introduces a fundamental administrative overhaul for directors and the self-employed. For the first time, HMRC will require taxpayers to include mandatory disclosures within their Self-Assessment returns, marking a decisive shift from the historically voluntary model. This reform reflects HMRC’s commitment to transparency and aligns Self Assessment with broader digital tax initiatives, such as Making Tax Digital.
Under these new rules, all individuals who begin or cease trading — or serve as directors of close companies — must disclose detailed information within their Self Assessment. This includes:
- The date trading began or ceased.
- The company’s name, registration number, and directorship details.
- Dividend income, shareholdings, and profit extraction methods.
Previously, HMRC relied on cross-referencing PAYE data, dividend vouchers, or corporate filings to fill in gaps. Now, directors themselves must report these details, ensuring accuracy at source. This change means that even small discrepancies between your personal return and company filings could automatically trigger an HMRC review.
The move toward real-time digital validation means that Self-Assessment data will be checked against Companies House and bank feeds almost instantly. HMRC’s AI-driven systems can now identify inconsistencies — for example, when dividends are declared in company accounts but missing from an individual’s tax return, or when shareholding details differ across records.
For directors, this highlights the importance of precision and early preparation. Rather than waiting for the year-end crunch, directors should integrate digital accounting platforms that can synchronise company data directly into Self Assessment-ready formats. Xero, QuickBooks, and Zoho Books already provide automated feeds and reconciliation tools that simplify this process.
Let’s take an example. A director of a small architectural firm in Farringdon earns dividends quarterly but doesn’t update records until year-end. Under the new system, HMRC could detect mismatches between the company’s quarterly submissions and the director’s annual filing, resulting in a compliance flag. With automated reconciliation in place, this risk disappears.
Furthermore, the new rules close long-standing loopholes around undisclosed start and cessation dates. Many self-employed individuals previously delayed formal registration or deregistration to manage cash flow — a practice that now carries greater scrutiny.
To remain compliant:
- Keep all director and shareholder details up to date.
- Maintain synchronised bookkeeping and tax software.
- Conduct quarterly reconciliations.
- Ensure that dividends and salaries align with board minutes and tax filings.
At CIGMA Accounting, we specialise in helping directors integrate these digital processes seamlessly. Our clients benefit from automated Self Assessment preparation that aligns with HMRC’s reporting standards, ensuring accuracy and peace of mind.

Dividend Reporting: What Changes in 2025–26
From April 2025, directors will face stricter obligations for reporting dividends as HMRC continues to bridge the data gap between company filings and personal Self Assessment returns. Under the new regime, every dividend payment—regardless of size or frequency—must be declared precisely. The days of rounding figures or relying on outdated dividend vouchers are over. HMRC’s systems will now automatically cross-reference company accounts, PAYE data, and bank transactions to verify reported amounts.
Why it matters: Dividends represent one of the most common ways directors extract profits from their companies. However, inconsistencies between corporate and personal filings have historically led to tax underpayments. The new framework ensures that all declared dividends match what appears in your company’s statutory accounts and bank feeds.
What directors must now include:
- The company name and registration number from which the dividend was received.
- The exact dividend amount paid in the tax year.
- The date the dividend was issued.
- The highest shareholding percentage held during the period.
Even where no formal dividend is paid, HMRC expects directors to maintain dividend vouchers and board minutes for all declared distributions. Digital bookkeeping software, such as Xero, QuickBooks, or Zoho Books, can automatically generate and store these records, thereby simplifying compliance.
Example: Imagine a director of a digital agency in Farringdon who withdraws £2,000 monthly as dividends but fails to create formal vouchers. When HMRC compares their company accounts (showing £24,000 distributed) against their personal return (which reports only £18,000), it automatically triggers a discrepancy notice. The resulting investigation could lead to penalties or reclassification of income as salary, which carries higher tax and National Insurance charges.
Key recommendations:
- Create board minutes for all dividend declarations, even for small amounts.
- Use digital vouchers to ensure real-time record-keeping.
- Reconcile company accounts quarterly to match dividend payments and shareholder records.
- Seek professional advice on the optimal split between salary and dividends to minimise exposure and maintain compliance.
Future direction: The change also integrates with HMRC’s broader Making Tax Digital initiative, meaning digital submission of dividend data may become standard within the next few years. Early adoption of automated accounting platforms will ensure a smooth transition once real-time dividend reporting becomes mandatory.
At CIGMA Accounting, we assist directors in designing clear dividend tax strategies that strike a balance between tax efficiency and compliance. Our systems automatically sync corporate and personal reporting, ensuring that every dividend is traceable, verifiable, and fully HMRC-ready.

Start or Cessation of Trade: No Longer Optional
Before April 2025, disclosing the start or cessation of trade was a voluntary act that many taxpayers overlooked — often unintentionally. However, under the new Self Assessment rules for 2025–26, this disclosure has become mandatory. This means anyone beginning a new business or ceasing operations must clearly state the date on which their trade began or ended within their Self Assessment return.
Failing to report these details can have serious consequences. For instance, late or inaccurate submissions may result in penalties ranging from £100 for a missed deadline to larger fines for unpaid tax. HMRC is paying particular attention to those who fail to declare the end of a business, since such omissions can leave tax liabilities open or lead to underpayment.
Consider a freelance designer who stops trading mid-year but forgets to record the cessation date. HMRC’s new cross-checking system will flag discrepancies between bank activity, VAT deregistration, and missing income. The same applies to limited companies that cease operations without formally updating their trading status.
To prevent errors, directors and the self-employed should document commencement and cessation dates in their bookkeeping software. Cloud platforms like Xero or QuickBooks can automatically tag these changes, ensuring that returns align with real-time financial data. Keeping digital records also helps maintain compliance with Making Tax Digital requirements.
Common pitfalls include:
- Forgetting to update HMRC when switching from sole trader to limited company status.
- Overlapping tax periods when trading halts mid-year.
- Claiming ongoing business expenses after cessation.
Example: A property consultant in London closed their business in July 2025 but continued to claim travel expenses until the end of the year. HMRC disallowed these deductions and added penalties for incorrect reporting.
Best practice: Maintain a compliance calendar to record significant business events, such as start dates, cessation dates, VAT changes, and directorship shifts, and review it quarterly with your accountant.

Compliance Risks and HMRC Enforcement
HMRC’s enforcement capabilities are evolving rapidly. The 2025–26 Self Assessment reforms give HMRC expanded access to digital data from Companies House, Open Banking, and even accounting software providers. The department uses artificial intelligence and machine learning algorithms to identify anomalies — such as dividend declarations that don’t match corporate filings, or PAYE submissions inconsistent with director records.
Case Example: In 2024, a London-based consultancy received an HMRC notice after inconsistencies were found between declared income and client invoices visible in their digital payment data. Although the discrepancy was slight, the inquiry led to a full compliance review.
Key enforcement priorities include:
- Detecting undeclared dividend income.
- Identifying directors who extract funds via loans without disclosure.
- Monitoring unreported business cessation dates.
- Cross-referencing VAT, payroll, and corporation tax submissions for inconsistencies.
Penalties now extend beyond monetary fines. Persistent non-compliance can lead to HMRC tagging a director’s record as high-risk, triggering closer scrutiny in future filings. In extreme cases, HMRC can launch civil or criminal investigations.
Prevention Strategies:
- Adopt integrated bookkeeping systems to synchronise personal and corporate records.
- Schedule quarterly reconciliation checks between Companies House and HMRC data to ensure accuracy.
- Retain all dividend vouchers, board minutes, and shareholder confirmations digitally.
- Engage professional advisors early if any discrepancies arise.

How AI, Automation, and Local Accountants Are Changing Director Compliance
The introduction of the 2025–26 Self Assessment reforms arrives at a moment when technology and accounting have never been more intertwined. Automation, artificial intelligence (AI), and cloud-based systems are reshaping how directors manage their finances — transforming compliance from a reactive process into a predictive, data-driven function.
AI and Automation: The New Compliance Backbone
AI-powered systems can now detect inconsistencies in real time, cross-checking Self Assessment data with company filings, banking transactions, and digital receipts. For example, AI-driven accounting tools such as Xero, QuickBooks, and Zoho Books use machine learning to categorise transactions accurately, flag anomalies, and even suggest potential tax deductions. This automation reduces the manual workload for directors and ensures reporting precision.
At CIGMA Accounting, we have integrated AI analytics into our workflow to anticipate compliance risks before they occur. Our hybrid approach combines human expertise with machine intelligence, allowing us to monitor client data across multiple systems and automatically reconcile dividend payments, payroll, and expense claims.
Local Accountants vs Remote Solutions
Directors often ask whether they should rely on a local accountant or a remote digital firm. The truth is, both models have their place. Local accountants offer personalised, face-to-face service, which is invaluable for complex cases or strategic planning. Meanwhile, remote accountants powered by AI-driven systems offer 24/7 accessibility, speed, and seamless integration with cloud platforms.
CIGMA’s hybrid model combines local expertise from our Wimbledon and Farringdon offices with a remote, technology-first infrastructure, ensuring constant oversight. This means clients get personalised advice underpinned by the reliability and precision of AI.
Why It Matters for Directors
The HMRC reforms emphasise accuracy and real-time transparency. Directors who adopt AI-assisted bookkeeping early will enjoy a distinct advantage. They will:
- Detect discrepancies before HMRC does.
- Reduce administrative overheads by up to 60%.
- Ensure every dividend, salary, and expense entry is verified digitally.
- Build audit-ready digital trails that withstand HMRC scrutiny.
For example, a director of a tech consultancy using CIGMA’s AI-linked platform receives instant alerts when a dividend voucher is missing or when an expense entry doesn’t match category rules. This proactive model prevents errors that could trigger penalties or investigations.
Preparing for the Future
As HMRC continues to evolve towards full Making Tax Digital compliance, integrating AI tools isn’t just optional — it’s essential. Businesses that adopt these systems early will streamline their compliance, enhance profitability, and gain sharper insights into their financial performance.

What Directors Should Do Now
The move toward mandatory Self-Assessment reporting for directors in 2025–26 requires a proactive and structured response. Acting early isn’t just about compliance — it’s about strengthening financial discipline, improving decision-making, and reducing the chance of errors that could lead to HMRC penalties. Below is an expanded, actionable guide outlining what every company director should do now to stay ahead.
- Audit Your Existing Filings and Company Data
Begin with a comprehensive reconciliation of your company’s filings across Companies House, HMRC, and your accounting software. Verify the accuracy of dividend reporting, shareholding percentages, and PAYE records. Even minor mismatches can trigger HMRC’s digital alerts. CIGMA’s AI-integrated audit tools automatically flag inconsistencies between your company’s statutory filings and Self-Assessment drafts — ensuring total alignment. - Digitise and Centralise Record-Keeping
Digital transformation isn’t optional anymore. By 2026, HMRC’s Making Tax Digital (MTD) will be expanded to cover most small companies and their directors. Cloud platforms like Xero, Zoho Books, and QuickBooks sync directly with your business bank feeds, allowing instant reconciliation of income, dividends, and expenses. Directors should ensure all dividend vouchers, share transfer records, and salary slips are uploaded to these systems. CIGMA helps clients implement end-to-end automation — from dividend declarations to document storage — creating a secure, paperless compliance framework. - Review Dividend and Salary Strategy
The new rules make dividend reporting more transparent, so directors should evaluate how they extract profits. A balanced combination of salary and dividends can reduce tax liabilities while staying compliant. Using forecasting tools, CIGMA’s accountants model different extraction scenarios to optimise cashflow and minimise tax exposure. This forward-looking approach ensures directors can plan quarterly, rather than reacting at year-end. - Schedule Quarterly Compliance Reviews
Quarterly reviews are now essential under digital reporting. These sessions align your business accounts with Self-Assessment data, ensuring all records are current and accurate. They also help directors make timely decisions about profit retention, shareholder distributions, and tax provisions. CIGMA’s quarterly review framework integrates with cloud platforms to produce live dashboards and automated discrepancy alerts. - Train Internal Teams and Maintain Transparency
Where a company has in-house bookkeepers or finance assistants, ensure they’re trained on the new reporting obligations. Transparency across your finance team reduces the likelihood of omissions or outdated reporting. CIGMA offers director-focused workshops that explain practical compliance workflows, ensuring your internal teams stay aligned with regulatory changes. - Choose the Right Accountant — Local, Remote, or Hybrid
Directors now have options: a local accountant for personalised, in-person support or a remote digital accountant for efficiency. However, the most effective model is hybrid — combining face-to-face strategic discussions with digital automation. CIGMA’s offices in Wimbledon, Farringdon, Sutton, and Canary Wharf offer precisely this approach — human expertise underpinned by AI-powered accuracy. - Integrate AI to Future-Proof Compliance
AI can detect errors, reconcile ledgers, and pre-empt reporting risks months before submission. For example, CIGMA’s automated systems cross-check director filings against company accounts daily, helping prevent missed dividend entries or shareholding inconsistencies. This predictive compliance model keeps directors ahead of the curve while freeing them from repetitive administrative work. - Plan for the Wider Compliance Shift
These changes are part of a broader trend toward digital-first governance. As HMRC integrates with global data exchange systems like the OECD DAC7 and CRS, directors will need full transparency across both domestic and overseas holdings. Preparing now means building systems that can handle cross-border data and real-time reporting.
In summary: Directors who act early — by auditing data, adopting automation, and engaging hybrid accounting expertise — won’t just comply; they’ll lead. CIGMA empowers directors to convert mandatory reporting into a strategic advantage through technology, foresight, and continuous support.

Broader Implications for Directors: The Bigger Picture
The 2025 Self Assessment reforms do not exist in isolation — they are part of a much larger evolution in how governments around the world manage taxation, compliance, and data sharing. For UK directors, understanding these broader implications is key to future-proofing their financial and operational strategies.
A Shift Toward Global Transparency
The UK’s new director reporting rules align with international frameworks such as the OECD’s Common Reporting Standard (CRS) and DAC7, which enable tax authorities across countries to exchange financial and ownership data. This means that directors who hold assets or operate subsidiaries abroad will find it increasingly difficult to conceal income or profits. Even if your company operates only within the UK, data shared through these systems can reveal cross-border transactions, payments from overseas clients, or foreign dividends.
Integration with Making Tax Digital (MTD)
HMRC’s Making Tax Digital initiative is the backbone of this transformation. It aims to make UK taxation entirely digital, ensuring that all business and individual financial records are reported in real time. For directors, this means that every entry — from payroll to dividends — will ultimately be integrated into a unified digital tax profile. The long-term vision is an ecosystem where data validation happens automatically, significantly reducing manual filings and the risk of error.
The Broader Business Impact
These reforms will not only change compliance but also reshape how companies plan for growth. Directors will have access to richer, real-time insights that support better decision-making. At the same time, increased visibility and transparency will raise expectations from investors, banks, and regulators. Companies with outdated systems or poor record-keeping will struggle to secure financing or establish business credit.
Consider how this affects a multi-director firm in London. Previously, year-end reconciliation was a manual process that was often delayed until filing deadlines approached. With HMRC’s digital oversight, delays or discrepancies will be immediately apparent, prompting earlier action. Forward-thinking directors can leverage this advantage by utilising accurate, real-time data for strategic planning, forecasting, and investor reporting.
A Future of Predictive Compliance
Looking ahead, AI-powered compliance will evolve from a support tool into a predictive system. Rather than waiting for HMRC audits, algorithms will alert directors to potential compliance gaps in advance. This proactive model, already in use by leading accounting firms, will become standard practice by the end of the decade.
The Takeaway for Directors
The directors who adapt early will gain a competitive edge. By embracing automation, AI, and integrated financial systems, they will not only meet HMRC’s expectations but also create stronger, more resilient businesses.
At CIGMA Accounting, we help directors interpret and act on these changes — aligning tax, technology, and compliance into a single, seamless strategy.

Practical Example: Director of a Close Company in Wimbledon
To illustrate how the new rules work in practice, consider Sarah, a director of a small design agency based in Wimbledon (SW19). Her business is a typical close company — she and one other partner own 100% of the shares, and she pays herself a modest salary alongside quarterly dividends. Until now, her compliance process has been straightforward: her bookkeeper maintained the accounts, and she filed her Self Assessment with basic dividend figures each year.
Under the April 2025 reforms, Sarah’s responsibilities have increased significantly. When completing her 2025–26 Self Assessment, she must now confirm:
She is a director of a close company.
Her company’s name and registration number.
The total dividends received during the year.
Her shareholding percentage at its highest point.
She must also ensure her company’s accounting records and personal Self Assessment align perfectly. Any mismatch could trigger an HMRC compliance flag. For instance, if her company accounts show £30,000 in dividends paid out but Sarah’s Self Assessment declares only £25,000, HMRC’s AI-based systems will immediately detect the discrepancy.
Alongside dividends, Sarah also receives Statutory Maternity Pay as a director — a benefit often misunderstood by owner-managers. Many directors fail to record maternity or paternity pay correctly within payroll and dividend structures, which can create discrepancies once the new HMRC systems begin real-time cross-checking.
As her family grows, Sarah later reviews childcare support and learns she may still be eligible for the free childcare scheme even while earning over £100,000. Understanding how salary, dividends, and benefits interact becomes essential for accurate reporting and more innovative tax planning — precisely the type of joined-up advice the new Self Assessment rules are designed to encourage.
How CIGMA’s Digital Systems Help Directors Like Sarah
1. Real-time data syncing: CIGMA connects Sarah’s business bank accounts and accounting software (e.g., Xero or QuickBooks) to ensure every dividend, expense, and salary transaction is automatically categorised and reconciled.
2. Automated Self Assessment preparation: Integrated systems pre-populate verified company data, reducing errors and ensuring consistency across HMRC and Companies House.
3. Quarterly compliance reviews: Our hybrid model provides scheduled reviews to catch issues early and keep filings aligned.
4. Tax planning support: We design optimal salary-dividend-benefit mixes that protect compliance while maximising efficiency.
5. AI-driven error detection: Our platform flags duplicate payments, anomalies, or missing documentation instantly.
Example outcome: Sarah’s 2025–26 return is submitted flawlessly. Her payroll, maternity pay, and dividend data match across all HMRC systems, keeping her penalty-free and improving her credit profile for future business financing.
Key takeaway for directors: The new regime is more than an administrative update — it’s a pathway to more innovative, cleaner, fully digital financial management. Directors who integrate AI-enabled accounting early will find compliance to be both seamless and strategic.
At CIGMA Accounting, we help directors across Wimbledon (south-west London), Farringdon (central London), and beyond transform regulatory change into a competitive advantage.

Frequently Asked Questions (FAQs)
Below are some of the most common — and often misunderstood — questions we receive from company directors preparing for the 2025–26 Self Assessment reforms. Each response has been tailored to help you stay compliant while optimising your financial planning.
Yes. Even if you take only a salary through PAYE, HMRC generally requires directors of limited companies to file annual Self Assessment returns. The 2025 reforms make this requirement more explicit, as directors must confirm their company name, registration number, and dividend income.
A close company is typically one controlled by five or fewer shareholders or a single director. Most small private limited companies fit this definition. HMRC pays special attention to close companies because of their potential for informal profit extraction.
Yes. Each directorship must be disclosed separately in your Self Assessment. You’ll need to provide company registration numbers and your highest shareholding percentage in each firm during the tax year.
If you use digital software such as Xero or QuickBooks, dividend data can be exported directly or integrated into your Self Assessment. Always double-check that dividend vouchers, board minutes, and shareholding details align across systems.
Absolutely. HMRC’s new digital data tools can identify when money leaves the business without proper classification. If director loans are not repaid within nine months of year-end, additional corporation tax (known as Section 455 Tax) may apply.
You must report the exact start and cessation dates in your Self Assessment. Missing or incorrect dates can delay refunds, trigger penalties, or create confusion about tax periods.
Yes, if the costs are genuinely business-related. You can claim a portion of rent, utilities, and broadband expenses used for business purposes. However, the apportionment must be reasonable and supported by documentation.
Possibly — the Rent-a-Room Relief allows you to earn up to £7,500 per year tax-free from letting furnished accommodation in your main home. However, if you exceed that limit or rent through Airbnb, standard property income rules apply.
HMRC’s AI-driven systems automatically cross-reference Self Assessment data with Companies House, bank feeds, and accounting software records. Any inconsistency can trigger a compliance review or automated query.
We provide a fully integrated compliance solution — linking your business accounts, payroll, and dividends to your Self Assessment. Our systems are designed to pre-empt discrepancies and ensure all reports align with HMRC’s digital requirements.
The 2025–26 Self Assessment reforms aren’t just another tax update — they’re a pivotal moment for directors across the UK. The difference between those who thrive and those who get caught off guard will come down to preparation, digital integration, and expert support.
