Do company directors need to file Self Assessment?

Companies and directors are taxed separately

A limited company pays Corporation Tax on its profits. Directors are individuals who manage the company but are not the company itself. Personal income received from the company — salary, dividends, expenses, and benefits — is taxed separately through Income Tax and National Insurance.

This split catches many new directors off guard. Completing the company's annual accounts and Corporation Tax return (form CT600) does not settle the director's personal tax position. When untaxed personal income exists, HMRC expects a Self Assessment return from the director as an individual.

Understanding which income streams pass through PAYE and which do not is the starting point for knowing whether filing is needed.

When directors must file

HMRC's starting position is that all company directors must register for Self Assessment and file a return, unless HMRC agrees otherwise.

The reason is that directors can receive income that is not taxed at source:

• Dividends — paid from company profits after Corporation Tax, with no tax deducted when paid
• Benefits in kind — company cars, private health cover, interest-free loans, and similar perks
• Expenses and payments — reimbursed costs that have a personal element
• Director's loans — money taken from the company that is not salary or a declared dividend

Even a director who takes no money from the company during the year may still receive a notice to file. HMRC treats the directorship itself as a reason to be in Self Assessment.

Directors can ask HMRC to remove them from Self Assessment if they genuinely have no untaxed income and no longer need to file. HMRC decides case by case. Until HMRC confirms removal, a notice to file must be answered.

Official guidance is on Company directors and Self Assessment.

When directors may not need to file

Some directors do not need a return if all of the following apply:

• The only source of income is employment taxed through PAYE
• Total income from all sources (including savings interest) is below £1,000 in untaxed income
• HMRC has not issued a notice to file (form SA316)

In practice, many directors receive dividends or benefits that push them above this threshold. A director with a small salary processed through the company PAYE scheme but who also receives dividends will almost certainly need to file.

The online checker at Check if you need to send a Self Assessment tax return gives a preliminary answer, though HMRC's notice to file overrides the checker result.

Registering as a director

Directors who are new to Self Assessment must register individually. Company registration at Companies House does not register the director for personal tax.

Registration is done through GOV.UK. HMRC sends a Unique Taxpayer Reference (UTR) by post, which can take up to 10 working days. The UTR is needed alongside a Government Gateway account to file online.

The step-by-step registration and filing process is in the how to file Self Assessment guide.

Directors should register promptly. The deadline for registration is 5 October after the tax year in which the directorship began or untaxed income first arose.

Salary and PAYE

Many directors pay themselves a salary through the company payroll. The company operates PAYE, deducting Income Tax and employee National Insurance before paying the director.

Salary processed correctly through PAYE is taxed at source. The director receives a P60 at the end of the tax year showing total pay and tax deducted. These figures go on the employment pages of the Self Assessment return (SA102).

A salary alone does not always remove the need to file. If dividends or benefits also exist, the return must include all income sources.

Directors who are the only employee of a small company often use an accountant or payroll software to run PAYE. Missing PAYE deadlines creates company penalties separate from personal Self Assessment penalties.

Dividends

Dividends are a common way for directors to take money from a company after Corporation Tax. They are not deductible for the company and are not taxed when paid — the director declares them on Self Assessment.

Key points about dividend tax:

• Each taxpayer has a dividend allowance (set each tax year by HMRC — check GOV.UK for the current figure)
• Dividends above the allowance are taxed at dividend tax rates, which differ from standard Income Tax rates
• Basic rate, higher rate, and additional rate taxpayers each face different dividend tax percentages
• Dividend vouchers from the company should be kept as evidence

If a director is also a shareholder — which is typical in owner-managed companies — all dividends received in the tax year are declared, not just those labelled as director's pay.

Full rates and allowances are on Tax on dividends.

Dividend income is entered on the dividend pages of the Self Assessment return. HMRC's online system calculates the tax due after applying the allowance and accounting for other income that may push the director into a higher tax band.

Benefits in kind

When a company provides non-cash benefits to a director, these are usually benefits in kind. Common examples include:

• Company cars available for private use
• Private medical insurance paid by the company
• Interest-free or low-interest loans from the company
• Living accommodation provided by the company
• Assets transferred to the director at below market value

The company reports benefits on form P11D (or through payrolling benefits if registered to do so). HMRC uses P11D data to check the director's return.

Benefits in kind are treated as untaxed income. The director pays tax on the cash equivalent value shown on the P11D. Some benefits also attract Class 1A National Insurance, paid by the company rather than the director.

Directors who receive only a salary with no benefits and no dividends may have a simpler return — but the directorship rule means HMRC often still expects filing.

Director's loans

When a director borrows money from their company and does not repay it within set time limits, HMRC treats the outstanding amount as a benefit or distribution. Tax consequences follow.

Loans over £10,000 at any point in the tax year trigger benefit-in-kind rules if interest is below the official rate. Loans not repaid within nine months and one day after the company's accounting year end may be subject to a Section 455 tax charge on the company.

Directors with loan accounts should keep clear records of money taken out and paid back. Accountancy support is common for this area because the rules are detailed.

What goes on the personal return

A director's Self Assessment return (SA100) pulls together all personal income for the tax year. Typical sections include:

Income type	Where it appears	Tax treatment
Director's salary	Employment pages (SA102) from P60	Taxed through PAYE; return reconciles total
Dividends	Dividend pages	Taxed at dividend rates above the allowance
Benefits in kind	Employment pages from P11D	Taxed as untaxed income
Bank interest	Interest pages	May be untaxed if above the personal savings allowance
Other income	Relevant supplementary pages	Depends on source

The return brings all sources together so HMRC can apply the correct tax bands. A director who is a basic rate taxpayer for salary might pay higher-rate dividend tax if total income crosses a threshold.

National Insurance on salary is handled through PAYE. Dividends do not attract National Insurance. This difference influences how directors structure their pay, though tax planning sits outside this guide's scope.

Company returns vs personal returns

Directors should keep two filing streams distinct:

Company obligations:

• Annual accounts filed at Companies House
• Corporation Tax return (CT600) filed with HMRC
• PAYE Real Time Information submissions if the company employs anyone
• VAT returns if the company is VAT registered

Personal obligations:

• Self Assessment return (SA100) for the director as an individual
• Personal tax payment by 31 January (and payments on account if applicable)

Missing the company return does not excuse a late personal return, and vice versa. Penalties apply separately.

The Self Assessment deadlines guide lists personal filing dates. Company accounts and Corporation Tax have different deadlines based on the company's accounting period.

Payments on account

Directors with significant personal tax bills may need payments on account — advance payments towards the next year's liability. These are due on 31 January and 31 July.

Payments on account apply when the previous year's Self Assessment bill exceeded £1,000 and less than 80% of the total tax was collected through PAYE. A director taking mostly dividends with a small PAYE salary often meets this condition.

The payments on account guide explains how the amounts are calculated and when a reduction request to HMRC is appropriate.

Removing the filing requirement

Directors who stop trading, resign from all directorships, and have no further untaxed income can ask HMRC to cancel Self Assessment.

HMRC will not automatically stop sending notices. The director must contact HMRC and explain the change in circumstances. Until written confirmation arrives, any notice to file remains binding.

Resigning as a director but continuing to receive dividends from shares held in the company does not end the filing requirement.

Common director situations

Director with salary only, no dividends or benefits — filing may still be required because of HMRC's general rule for directors. Check with HMRC or use the online checker.

Director of a dormant company — if the company has no activity and the director receives no income, HMRC may agree to remove the Self Assessment requirement. The directorship alone can still trigger a notice.

Multiple directorships — all income from every company is combined on one personal return.

Director who is also self-employed — both employment and self-employment pages are needed. The sole trader Self Assessment guide covers the self-employment sections.

Non-resident directors — different rules may apply for UK tax residence. Residence status determines how much UK income is taxable.

Penalties for not filing

Ignoring a notice to file leads to automatic penalties, starting at £100 if the return is one day late. Further penalties accrue after three months, six months, and twelve months. Late payment interest and penalties apply separately.

HMRC does not waive penalties because a director believed the company accountant handled personal tax. Personal Self Assessment is the director's responsibility.
