Self Assessment Return for Limited Company Director Drivers: Step by Step

A Self Assessment return is usually needed if you drive through your own limited company and take dividends, because dividends are not taxed through payroll. Your salary and benefits go on the Employment pages, your dividends go on the main return, and the company files its own paperwork separately.

This guide walks through that personal Self Assessment return in order, from the paperwork you collect to the final payment. It also covers something many director guides have not caught up with: new boxes on the 2025/26 Self Assessment return that ask about your company. If you are still choosing a structure, read our sole trader versus limited company comparison first.

Key takeaways

• The return due online by 31 January 2027 covers 2025/26, so it uses that year's dividend rates of 8.75%, 33.75% and 39.35%, not the higher 2026/27 rates.
• A one-driver company is almost always a close company, so the 2025/26 Employment pages ask for its name, registration number, your dividends and your shareholding.
• App earnings belong to the company. They do not go on your personal return unless you were still a sole trader for part of the year.
• Your personal tax year and your company's accounting year rarely match, so sort every dividend voucher by date before you enter a total.
• Salary and dividends do not count towards Making Tax Digital for Income Tax, although self-employment and property income do.

What is a Self Assessment return for a company director?

A Self Assessment return is your personal yearly report to HMRC of income for the tax year from 6 April to 5 April. For a director-shareholder it shows salary, benefits and dividends received from the company. It does not report the company's own fares, costs or profit.

That last point trips up drivers who were once sole traders. As a sole trader, your driver app statement fed your Self Assessment return directly. Once the company holds the contract, that statement feeds the company's books instead, and your personal return only starts where the money reaches you.

Do limited company drivers need a Self Assessment return?

Most do, but not simply because they are directors. GOV.UK's list of who must file does not name directors as a group. You generally need a return because you have dividends above your unused allowances, other untaxed income, or a notice from HMRC telling you to file one.

Published guides disagree on whether a Self Assessment return is automatic, so it helps to work from the triggers themselves. The usual ones for a driver are listed below. The Association of Taxation Technicians also reports HMRC's view that a director with no other reason to file does not need to register just because of the new director boxes, in its note on the additional information rules.

• HMRC has sent you a notice to file, or a letter asking for a return. You must respond by the date on the letter.
• You received dividends above both your unused Personal Allowance and the £500 dividend allowance.
• You owed the company more than £10,000 at any time in the year, or you have other benefits that need reporting.
• You have other untaxed income, such as rent, savings interest or a sole trader period.
• You need to claim a relief, such as mileage allowance relief on a shortfall from your company.

If this is your first return for 2025/26, the 5 October 2026 registration date has passed. GOV.UK warns that telling HMRC after that date could lead to a penalty, so register now rather than waiting. Choose the route for people who are not self-employed, unless you also had a sole trader period.

How do you complete a Self Assessment return as a director, step by step?

Confirm the tax year, gather your payroll and dividend records, then enter your salary and director details on the Employment pages. Add benefits, enter dividends on the main return, add any other income and reliefs, then check the calculation. File online and pay by 31 January after the tax year.

1. Confirm the year. The return due by 31 January 2027 covers 6 April 2025 to 5 April 2026, so use that year's rates and that year's documents.
2. Build your document pack: P60, P11D if you have one, every dividend voucher and set of minutes, your director's loan account balance, and your company mileage claims.
3. Sign in with your personal UTR, not the company's, and add the Employment pages (form SA102) to your return.
4. Enter pay in box 1, tax taken off in box 2 and the company's PAYE reference in box 4, using the P60 figures.
5. Tick box 6 to say you were a director, tick box 7 if the company was close, then complete boxes 7.1 to 7.4.
6. Copy each P11D benefit to boxes 9 to 16, and claim any employment expenses the company has not reimbursed.
7. Enter your tax-year dividend total in box 4 on page TR 3 of the main return, and check it agrees with box 7.3.
8. Add anything else: savings interest, rent, a sole trader period or a capital gain, each on its own section or supplementary page.
9. Review the calculation, file online by 31 January, and pay the balance plus any payment on account due the same day.

Which income goes where on the return?

Salary and benefits go on the Employment pages, because a director is treated as an office holder paid through the company. Dividends go on the main return, because they come from your shares rather than your job. App earnings and company costs stay in the company's records, away from your personal return altogether.

Salary: boxes 1, 2 and 4

Take your pay and tax from the P60, which GOV.UK says your company must give you by 31 May if you were still working for it on 5 April. If you ran payroll yourself, your payroll software should produce it. Our PAYE payroll set-up guide covers the set-up if you have not started.

Box 4 needs the company's PAYE reference. HMRC's notes say to write "None" there if the employer has no PAYE reference, which can apply if you paid yourself no salary at all. Do not borrow a reference from another employer. Use a separate Employment page for each job or directorship.

Benefits: boxes 9 to 16

Your P11D lists benefits such as a company car, and its sections map to these boxes. HMRC's notes say to contact your employer if you have no copy by 6 July 2026. In a one-driver company that employer is you, so that date is really a reminder to yourself.

Some benefits are taxed through payroll instead of a P11D. Those normally sit inside your P60 pay already, so check before you add them a second time. The car question itself is covered in our limited company mileage allowance guide, so we will not repeat it here.

What are the new director boxes on the 2025/26 Self Assessment return?

Boxes 6 to 7.4 on the Employment pages ask whether you were a director, and whether the company was close. If it was, you give its name, registration number, the dividends you received from it and your highest percentage shareholding. These requirements begin with the 2025/26 tax year.

The rule comes from regulation 5 of the Income Tax (Additional Information to be included in Returns) Regulations 2025, and HMRC updated its SA102 Employment notes for directors on 8 September 2026. If you read a guide written before that date, it may not reflect the current wording.

• Box 6: mark it if you were a company director, and the notes include directors of dormant companies.
• Box 6.1: enter the date you stopped, if your directorship ended before 6 April 2026.
• Box 7: mark it if the company was close. A UK-resident company controlled by its directors, or by five or fewer participators such as shareholders, will be close.
• Box 7.1: the company's full name, exactly as registered.
• Box 7.2: the company registration number from Companies House. This is not your UTR or your PAYE reference.
• Box 7.3: dividends received from this company in the tax year, entering zero if there were none.
• Box 7.4: your percentage of the share capital, based on nominal value, using the highest figure during the year.

A company you do not earn from can still matter. The notes bring in directors of dormant companies, and the ATT reports HMRC's position that it expects a separate Employment page for each directorship, even with no pay. So if you have an old company from a previous venture, it probably needs its own page if you are filing a return anyway.

The notes carve out unpaid directors of registered charities and community interest companies that received no income or distributions from them. The ATT also reports that HMRC treats the requirement as a single composite duty, with one £60 penalty per return. Check HMRC's latest position before relying on this, because first-year treatment was still under discussion when the ATT wrote in July 2026.

How are dividends taxed on the return you file now?

Dividends are taxed in the year you received them, on top of your other income. The first £500 is covered by the dividend allowance. The rest is taxed at 8.75%, 33.75% or 39.35% for 2025/26, depending on your band. Rates for 2026/27 rise to 10.75% and 35.75%.

According to GOV.UK's income tax rates and allowances, the Personal Allowance was £12,570 in 2025/26, with £37,700 of basic rate income after that. Salary uses your allowance first, and dividends sit on top. If you live in Scotland, your salary bands differ, so check GOV.UK before you estimate your bill.

A dividend belongs on the Self Assessment return for the tax year you received it, so the date matters. GOV.UK says each voucher should show the date, the company's name, the shareholders' names and the amount. Hold a directors' meeting and keep minutes too, even as the only director. A transfer with no paperwork may end up looking like a director's loan instead.

How does the return fit around the company's own filings?

The two sets of filings run on separate calendars. Your Self Assessment return follows the tax year to 5 April and is due the following 31 January. The company's accounts, Corporation Tax and Company Tax Return count from its own year end, so a dividend can sit in different periods for each.

Those company dates come from GOV.UK's guide to annual accounts and Company Tax Returns: accounts within 9 months of the year end, payment 9 months and a day after the accounting period, and the return within 12 months. The confirmation statement runs on its own date, shown on your Companies House record. GOV.UK also gives 30 December 2026 as the online filing date if you want a balance collected through your tax code and you qualify. Our key tax dates guide sets out the wider calendar.

Do the accounts first if you can

With a March year end, the accounts deadline falls before your personal deadline. Finishing them first shows whether the company had enough profit for the dividends it declared, because GOV.UK says dividends cannot exceed available profits. It also gives you an up-to-date director's loan balance before you file.

Watch the director's loan account

According to GOV.UK's guide to owing your company money, a loan still unpaid 9 months after the accounting period triggers a Corporation Tax charge of 33.75% on the amount outstanding. Over £10,000 at any time in the year, it is also treated as a benefit in kind, and you report it on your return.

What changes in the year you incorporated?

Your Self Assessment return can show both lives. Fares earned before the company took over go on the self-employment pages, with your own mileage and costs. Salary and dividends after that go on the Employment pages and main return. The company's own income stays out of your personal figures from its start date.

Mileage needs care in that year. On a 2025/26 return, the sole trader flat rate is 45p for the first 10,000 miles and 25p after that, because the 55p rate only applies from 6 April 2026. HMRC's notes give the same 45p and 25p as approved rates for 2025/26 employee claims. Our note on what changed for 2026/27 explains the rise.

Does Making Tax Digital apply to a limited company driver?

Not on salary and dividends alone. HMRC's guidance says employment income and dividends, including those from your own company, do not count as qualifying income. It only counts self-employment and property income, so a director with neither of those stays on the ordinary annual Self Assessment return instead of quarterly updates.

According to HMRC's qualifying income guide, the thresholds are above £50,000 from 6 April 2026, £30,000 from April 2027 and £20,000 from April 2028. A director with a rental flat or a separate sole trade could still be caught. Our comparison of Self Assessment and Making Tax Digital shows what would change.

Illustrative example: Tariq's 2025/26 return

This is an illustrative example with an invented driver and our own figures. Tariq owns all the shares in his company and lives in England. In 2025/26 he took a £12,570 salary with no tax deducted, plus £30,000 of dividends. He has no other income, and we ignore National Insurance here.

His company reimbursed 12,000 business miles at 35p, which is £4,200. The approved amount for that year was 10,000 miles at 45p plus 2,000 at 25p, or £5,000. So he can claim the £800 shortfall as an employment expense.

• Salary after the £800 relief: £11,770, all covered by the £12,570 Personal Allowance.
• Unused Personal Allowance of £800, which is set against dividends: £30,000 less £800 leaves £29,200.
• Dividend allowance on the first £500, leaving £28,700 at 8.75%: £2,511.25 of tax.
• First payment on account, half of that bill: £1,255.63 (rounded), due with the bill. GOV.UK requires these unless last year's bill was under £1,000 or over 80% of your tax was paid outside Self Assessment.
• Total due by 31 January 2027: £3,766.88. Second payment due by 31 July 2027: £1,255.63.

On his Self Assessment return, Tariq enters £12,570 in box 1, £0 in box 2 and his PAYE reference in box 4. He ticks boxes 6 and 7, gives the company's name and number, and enters £30,000 in both box 7.3 and box 4 on page TR 3. Box 7.4 shows 100%.

Next year needs planning. If he takes the same £30,000 in 2026/27 and, for simplicity, the same £800 relief, the 10.75% rate gives £3,085.25 on £28,700. That is £574 more than this year's tax, and his payments on account will not have allowed for it. You can test your own figures with our tax calculator.

What are the common mistakes and the penalties they trigger?

The usual errors are filing late, leaving out the new director boxes, using the wrong year's dividend rates, and reporting company income as personal income. Some carry fixed penalties, and others lead to extra tax and interest. A late return costs £100 at once under GOV.UK's penalty rules, even with no tax due.

• Filing after 31 January: according to GOV.UK's penalty table, £100 at once, £10 a day after 3 months up to £900, then the greater of 5% of the tax due or £300 at both 6 and 12 months.
• Paying late: 5% of the unpaid tax at 30 days, 6 months and 12 months, plus interest on the outstanding amount.
• Missing boxes 7.1 to 7.4: the ATT reports one £60 penalty per return, and the omission could also draw questions from HMRC.
• Registering after 5 October: GOV.UK warns this could lead to a penalty, so register as soon as you spot the problem.
• Using 2026/27 rates on a 2025/26 return: your bill is wrong, and correcting it may mean an amended return and interest on any underpayment.
• Taking money with no dividend paperwork: it may be treated as a director's loan, which can bring the 33.75% company charge and a benefit in kind.
• Forgetting the company has a separate UTR: quoting the wrong one can delay your filing, and any delay beyond the deadline brings the penalties above.
