Do Directors Have to Complete a Self Assessment Tax Return?

This guide from Tax Return Accountants covers everything you need to know about do directors have to complete a self assessment tax return, so you can stay compliant with confidence.

Do Directors Have to Complete a Self Assessment Tax Return? (2025/26 & 2026/27 Rules Explained)

Over 800,000 HMRC late filing penalties were issued in 2024/25 for missed or incorrect returns (source: GOV.UK).

Most directors are required to file a Self Assessment tax return unless every penny of their income is taxed at source and HMRC has confirmed that no return is required. This means that if you receive dividends, rental income, or benefits in kind, you almost certainly fall within HMRC’s scope. The rules are not automatic: you must actively check each year whether your circumstances have changed, and whether HMRC has issued a notice to file.

For example, a director in Leicester who only receives a modest PAYE salary (with no dividends or other income) and receives no notice from HMRC may not have to file. However, if that same director starts receiving dividends, even below the dividend allowance, a return is required. This is a common misconception—dividend income always needs to be declared, even if you believe it is covered by the allowance.

The deadlines are strict: paper returns must be received by 31 October following the end of the tax year, and online returns by 31 January. For the 2025/26 tax year, that means 31 October 2026 (paper) or 31 January 2027 (online). For 2026/27, it’s 31 October 2027 and 31 January 2028. Payment is also due by 31 January. Missing these deadlines means instant penalties.

Director tax return rules differ from those for sole traders and employees. A sole trader must always file, while employees only file if they have non-PAYE income or are required by HMRC. Directors sit between these: most must file, but not absolutely all.

Self Assessment for Directors: HMRC Filing Requirements

HMRC expects directors to file if they receive any personal income not taxed at source, or if they are issued a notice to file. Ignoring a notice is never an option—penalties apply even if you believe you owe no tax.

Exceptions: When directors might not need to file

Directors with only a PAYE salary, no dividends, and no other income may be exempt if HMRC confirms in writing that no return is required. Always keep this confirmation for your records.

How this differs from sole traders or employees

Sole traders must always file. Employees only file if they have other income or are told by HMRC. Directors are in a unique position—most must file, but not all, so check your status each year.

Director Tax Responsibilities in the UK: What You Must Report

Directors have a legal duty to declare all forms of personal income, not just salary.

• Salary (taxed via PAYE—usually reported automatically)
• Dividends (often not taxed at source—must be declared)
• Benefits in kind (company car, health insurance, etc.)
• Rental income or other side income
• Interest from company loans or investments

While salary is generally taxed through PAYE, dividends and benefits in kind are not. This is why most directors fall within the Self Assessment regime. It’s also why many are surprised by their obligations after their first year in office.

The table below shows the difference between income types and how they are taxed or reported:

Understanding these responsibilities is crucial. For instance, a Birmingham-based director who forgot to report £2,000 in dividends was issued a £100 late filing penalty plus interest—despite believing the amount was “too small to matter.”

Types of income directors must declare

Declare all income not taxed at source, including dividends, benefits, and rental income. Don’t rely on the company’s payroll alone.

Dividends, benefits, and other sources

Dividends and benefits are the main triggers for Self Assessment. Even if you reinvest dividends, you must declare them.

Understanding director NICs and PAYE

National Insurance Contributions (NICs) are paid on salary above the primary threshold (£12,570 for 2025/26). Dividends are not subject to NICs but are taxed at dividend rates.

When Do Directors Need to File a Tax Return? Key Triggers and Deadlines

Deadlines are strict: for paper returns, submit by 31 October after the tax year ends (31 Oct 2026 for 2025/26, 31 Oct 2027 for 2026/27). For online returns, the deadline is 31 January (31 Jan 2027 for 2025/26, 31 Jan 2028 for 2026/27). Payment is also due by 31 January.

Common triggers for Self Assessment include receiving dividends, rental income, or benefits in kind. Even if your tax bill is zero, missing the deadline means a £100 penalty. After three months, HMRC adds £10/day (up to £900), and after six and twelve months, a further 5% of tax due or £300 (whichever is greater).

For VAT deadlines, see our VAT Returns Service.

Deadlines for 2025/26 and 2026/27 tax years

Register by 5 October after your first year as a director. Paper deadline: 31 October; online: 31 January. Payment: 31 January. For payment via PAYE, submit by 30 December.

Common triggers for Self Assessment

Dividends, benefits, rental, and untaxed income are the main triggers. However, an HMRC notice always takes precedence—respond even if you think you’re exempt.

Penalties for late filing: What directors need to know

Penalties escalate quickly: £100 on day one, £10/day after three months, and 5% or £300 after six and twelve months. In addition, interest accrues on unpaid tax.

Scenario: A Director’s Self Assessment Journey (Real-World Example)

• Sarah, a Manchester-based director, receives a small PAYE salary, quarterly dividends, and rental income from a flat.
• She must report all dividend and rental income, even though her salary is taxed through payroll.
• With professional support, Sarah’s return is accurately filed by 31 January 2027, and she claims allowable expenses on her rental property.
• Without filing, Sarah would face a £100 penalty on 1 February, plus £10/day after three months and interest on unpaid tax.
• After switching to Tax Return Accountants, Sarah saved £400 by claiming overlooked expenses and avoided all penalties.

For help with your records, see our Bookkeeping Service. For more on finding a regulated adviser, check the ICAEW directory.

Meet Sarah: Director with dividends and salary

Sarah’s situation is typical—her salary alone would not require a tax return, but dividends and rental income do.

What she needed to declare

All dividends, rental income, and benefits in kind—regardless of amount—must be reported.

Outcome: Filing done right vs. penalties

As a result, Sarah avoided late filing penalties and reduced her overall tax bill with expert help.

Self Assessment Guide for Directors: Step-by-Step Filing & Checklist

1.5 million+ UK businesses are now enrolled in Making Tax Digital for VAT and Income Tax (source: GOV.UK).

Directors must register for Self Assessment by 5 October after their first tax year in office. You will need your Unique Taxpayer Reference (UTR), company details, P60 or P11D (if applicable), dividend statements, and details of any rental or other income. Overall, this paperwork forms the basis of your return and is essential for accurate reporting.

Before you submit, double-check all figures, review dividend and benefit entries, and confirm you’re using the correct Self Assessment deadline UK for your tax year. In fact, many directors are caught out by missing the 31 January online deadline, especially if they are new to the process or have left it to the last minute.

Here’s a simple checklist to follow before submitting your return:

• Register for Self Assessment with HMRC by 5 October
• Gather your UTR, P60/P11D, dividend and rental statements
• Check all figures match your bank statements and company records
• Review your tax code and any benefits in kind
• Submit online by 31 January (paper by 31 October)
• Pay any tax due by 31 January to avoid interest

As a result, missing any of these steps can lead to errors, delays, or penalties. For payroll queries, see our Payroll Service. For registration help, visit GOV.UK.

Registration and UTR: How to get started

Register online or by phone. HMRC will post your UTR—keep it safe, as you’ll need it every year.

What documents you’ll need

UTR, P60/P11D, dividend statements, rental income details, and any benefit statements.

Checklist before you submit

Double-check all income, review for missing dividends or benefits, and ensure you meet the correct deadline.

Director Tax Return: DIY vs Professional Accountant (Fees & Risks)

DIY filing is possible but risky—professional support can mean real savings and peace of mind.

Directors can file their own returns using HMRC’s online service or commercial software. This may seem cheaper—software costs £0-£50—but it typically takes 6-12 hours for a first-timer. In addition, the risk of errors is high, and HMRC offers only limited support for complex director queries. As a result, a single mistake can trigger a £100 penalty or lead to missed tax reliefs worth hundreds of pounds.

Professional accountants typically charge £200-£800+ for a director’s return, depending on complexity and the level of advice included. This covers not only the return itself but proactive tax planning, representation in case of HMRC queries, and reminders for all deadlines. In 2025, a Nottingham director who switched to Tax Return Accountants after a £100 penalty found £350 in missed allowable expenses—more than covering our fee.

For a breakdown of our fees, see Accountant Pricing. To find a regulated professional, check the ACCA directory.

DIY vs professional: cost and confidence

DIY is cheaper up front but riskier. Accountants offer confidence, advice, and HMRC representation.

Typical accountant fees for director returns

Expect £200-£800+ depending on complexity, number of income sources, and support required.

Risks of mistakes and missed tax reliefs

Missed reliefs and errors often cost more than the accountant’s fee. HMRC penalties and interest can add up quickly.

What If You Get It Wrong? Penalties, Amendments & How Accountants Help
