Dividend Tax Explained for Company Directors
.jpg)
Miss the 31 January deadline by a single day and HMRC charges you £100. It does not matter if you owe no tax at all. The penalty arrives anyway.
That small fact catches out more company directors than almost any other. Many assume that because the company has an accountant, and because they receive a payslip, their personal tax is dealt with. Then a letter arrives, and the surprise is rarely pleasant.
I hear the same question every year from directors across Tunbridge Wells, Tonbridge, Sevenoaks and Maidstone: "Do I really have to do a personal tax return as well as the company accounts?" The short answer is that most directors do, and the exceptions are narrower than people expect. The long answer is worth knowing, because it affects when you register, what you report, how much you pay and when you pay it.
This guide explains when registration is required, what income goes on the return, how dividends are treated, and the mistakes I see most often. I have used the 2026–27 rules throughout, and I have worked through an example so you can see the numbers.
Most company directors who take dividends need to complete a Self Assessment tax return. A director who is paid only through the company payroll, takes no dividends and has no other untaxed income may not need to. But once you receive dividends above your allowance, rent out a property, sell an asset at a gain or have other untaxed income, the return usually becomes necessary.
There is a second, simpler rule. If HMRC writes to you and asks you to complete a return, you must do so, whether or not you think you owe anything. Ignoring the letter is not an option.
Here is the part that surprises people. The company's accounts and tax return are completely separate from your personal return. The company is one legal person. You are another. Each has its own forms, its own deadlines and its own penalties. Filing one does not satisfy the other.
The question isn't whether you are a director. It is whether you have income that HMRC has not already taxed. Salary paid through payroll has had tax deducted at source, so it is generally "taxed". Dividends are paid without any tax being deducted, so they are "untaxed". That is the reason almost every working director with dividends ends up in Self Assessment.
HMRC lists several triggers. These include being self-employed as a sole trader with earnings over £1,000, being a partner in a business, having to pay Capital Gains Tax on a disposal, owing the High Income Child Benefit Charge without paying it through your tax code, and having untaxed income such as dividends, rent, savings interest or foreign income. A director can easily meet more than one at the same time.
There are exceptions, though they are narrower than people hope. A director who is paid only through payroll, who takes no dividends, and who has no director's loan benefit or other untaxed income normally doesn't need to file. A director of a genuinely dormant company that has never traded or paid anything out normally doesn't either. A director whose only untaxed income is small and falls within the Personal Allowance and the £500 dividend allowance may not need to file, although many still choose to do so to keep things clear.
I would add a word of caution. Not needing to file is not the same as not needing to tell HMRC. If you receive dividends above your allowance, HMRC's own guidance says you need to report them. For a working director, the usual way to do that is Self Assessment. Don't rely on a rule of thumb you heard from a friend. Check your own position, or ask us to check it.
If you need to file a return and you haven't done so before, you must register with HMRC by 5 October following the end of the tax year. For the 2025–26 tax year, that date was 5 October 2026. For dividends paid in 2026–27, it is 5 October 2027.
Registration produces a Unique Taxpayer Reference, usually called a UTR, which is sent by post. That can take up to around ten working days, and sometimes longer. Do not leave it until the week of the deadline.
A few years ago I met a director in Paddock Wood who had run a small marketing company for three years. He paid himself a small salary through payroll and took the rest as dividends, but he had never registered for Self Assessment. His previous bookkeeper had told him that "the company handles it". It doesn't. We registered him, filed three years of returns and agreed a payment plan with HMRC. The penalties and interest were painful. The worst of it was that every pound of that cost was avoidable with a single form, filled in on time.
Once you are in Self Assessment, the return needs to show everything you earned personally in the tax year. The tax year runs from 6 April to 5 April. It has nothing to do with your company's year-end.
If the company pays you a salary through payroll, it reports that to HMRC, and you report the same figures on your return. Your P60 or your final payslip shows the amount of pay and the tax deducted. For many directors, the salary is small, often around the Personal Allowance of £12,570, so the tax deducted is often nil. It still goes on the return.
Dividends are the main reason directors file. Every dividend you receive in the tax year is reported, including the part that falls within the £500 dividend allowance. I cover dividends in their own section below.
If the company provides benefits, such as a company car, private medical insurance, or an interest-free loan above £10,000, they are reported by the company on a form called a P11D and then included in your return. A company car, for example, is taxed on a percentage of its list price. Our guide on whether your company should buy a car explains how that works.
If you owe the company more than £10,000 at any point in the year and the loan is interest-free or low-interest, that can be a taxable benefit. If it is repaid late, the company may also have a section 455 charge. The loan itself is a company matter, but the benefit is yours to report. Our guide to director's loan accounts explains the rules.
Anything else you earn in the year goes on the return too. That includes rental income from property, interest on savings above your allowance, income from a second job or self-employment, and foreign income. It also includes capital gains if you sell shares, a second property or other assets.
The return is also where you claim certain reliefs. These include personal pension contributions that have received tax relief at source, Gift Aid donations and certain other items. Both of these also matter if your income is close to £100,000, which is covered in our guide to the £100,000 tax trap.
If you have a student loan, any repayments due on your dividend income are collected through Self Assessment. If you or your partner receive Child Benefit and your adjusted net income is high enough, the High Income Child Benefit Charge is calculated here too. These can add hundreds or thousands of pounds to the bill, and they are easy to overlook until the figure appears.
Dividends deserve their own treatment because they cause more personal tax confusion than anything else.
A dividend is paid to you from the company's profits after Corporation Tax. No tax is taken off when you receive it. For 2026–27, the first £500 of dividend income each year is tax-free. After that, dividends are taxed at 10.75% in the basic rate band, 35.75% in the higher rate band and 39.35% in the additional rate band. The rate you pay depends on your total income, because dividends are treated as the top slice.
A dividend is taxed in the year you receive it. If you vote a dividend in March but pay it in April, it falls in the later tax year. This gives you some control. A dividend paid on 4 April lands in one year, and the same dividend paid on 7 April lands in the next. For directors close to a tax band, the choice can be worth a great deal.
Your return needs the gross amount of every dividend and the date you received it. The dividend vouchers issued by the company are your evidence. If your records are patchy, now is the time to tidy them. Our guide to how Corporation Tax and dividends work together explains what the paperwork should include.
Some directors ask whether the tax on a dividend can be collected through a change to their tax code instead of a return. For a working director with regular, sizeable dividends, this is rarely a practical route. The amounts are variable, the code adjusts slowly, and HMRC will often expect a return in any event. If you receive a notice to file, you must file.
Take a Sevenoaks director who is paid a salary of £12,570 and receives dividends of £60,000 during the 2026–27 tax year. Their salary uses the whole Personal Allowance.
Of the £60,000, the first £500 is covered by the dividend allowance. The basic rate band is £37,700, so the next £37,200 is taxed at 10.75%, which is £3,999. The remaining £22,300 falls in the higher rate band and is taxed at 35.75%, which is £7,972.25. The total dividend tax is £11,971.25.
Because the dividend tax has not been collected in advance, the director pays it through Self Assessment. The return for 2026–27 must be filed online by 31 January 2028, and the tax is due on the same day.
And now the part that shocks people. In the first year, HMRC normally also collects a first "payment on account" towards the following year's tax. Payments on account are advance instalments, each equal to half of the previous year's bill, due on 31 January and 31 July. So on 31 January 2028, the director would pay the full £11,971.25 balance plus a first payment on account of about £5,985.63. That is £17,956.88 in one go.
I call this the January surprise. It isn't a penalty, and it is not extra tax. It is next year's tax paid early. But if you have not planned for it, it can feel like a punch.
Payments on account apply when your previous bill is above £1,000 and you did not pay at least 80% of your tax through deduction at source. A director who takes dividends will almost always meet that test.
Here are the dates and penalties that matter. They are the same for every taxpayer, directors included.
For the 2025–26 tax year, the deadlines are 5 October 2026 to register, 31 October 2026 for a paper return, and 31 January 2027 for an online return and for payment. A second payment on account is due on 31 July. For the 2026–27 tax year, the dates are the same each year, so the online deadline is 31 January 2028.
If you file late, the penalty is £100 straight away, even if nothing is owed. After three months, daily penalties of £10 begin, up to a maximum of £900. After six months there is an additional charge of 5% of the tax due or £300, whichever is higher. After twelve months, there is another.
If you pay late, there is a penalty of 5% of the unpaid tax at 30 days, at six months and at twelve months. Interest is charged on top, from the due date.
Let's go back to the Sevenoaks director with £11,971.25 of tax. Suppose they both file and pay seven months late. They would face £100 for the initial penalty, £900 in daily penalties, and £598.56 for the six-month charge, a total of about £1,599 for filing late. They would also face two late payment penalties of £598.56 each, about £1,197. The total is roughly £2,796, before interest. And that for a tax bill that would have cost nothing extra if paid on time.
You may have heard that Making Tax Digital for Income Tax began on 6 April 2026. It applies to self-employed people and landlords whose gross income from those sources is above £50,000, with the threshold falling to £30,000 in April 2027 and £20,000 in April 2028. It does not apply to salary or dividends. So a director whose income is purely from their own company is not in scope for that reason alone. If you also run a sole trade or let property, the position could be different, so ask us.
The company accounts and your personal return are separate jobs. Unless you have asked us to prepare your Self Assessment, nobody is filing it for you.
The 5 October deadline is easy to forget, and the UTR takes time to arrive. If you took your first dividend in the last tax year and have not registered, do it now.
Every dividend must be reported, including those within the £500 allowance. HMRC receives information from the company and from other sources. A mismatch invites enquiries.
A company car, a private medical policy or an overdrawn director's loan account can all create a taxable benefit. If your accountant isn't told about them, they can't be reported.
Your company might end its year on 31 March, but your personal tax year ends on 5 April. Dividends are taxed in the year they are paid, not the year the company earned the profit.
Dividend tax isn't deducted when you receive the money. If you spend the whole amount, you will be short in January. I tell clients to put aside about a third of any dividend in a separate account as soon as it arrives, and to adjust that figure once we have worked out their actual rate.
The January surprise is real. Plan for it a year ahead.
The £100 penalty applies even when there is nothing to pay. A "nil" return still needs to be on time.
Dividend tax rates, allowances and thresholds have all changed in recent years. The Autumn Budget is due on 28 October 2026, so check the position again before making a large decision.
Quick answer: Most company directors who receive dividends need to complete a Self Assessment tax return, because dividends are untaxed income. A director paid only through payroll, with no dividends, no benefits and no other untaxed income, may not need to. If HMRC asks you to file, you must.
What this means for a company director: Your personal tax and your company's tax are completely separate. You need to register for Self Assessment by 5 October after the end of the tax year in which you first need a return, file online by 31 January and pay any tax due by the same date. The company's accountant doesn't file your personal return unless you have asked them to.
Example: A director paid a salary of £12,570 and dividends of £60,000 in 2026–27 pays dividend tax of £11,971.25. On 31 January 2028 they pay that balance plus a first payment on account of about £5,985.63, a total of £17,956.88. If they file and pay seven months late, the penalties come to about £2,796 before interest.
Common mistakes: Assuming the company handles your return. Missing the 5 October registration date. Leaving out dividends or benefits. Not saving for the tax. Forgetting payments on account. Filing late because no tax is due.
When should you speak to an accountant? As soon as you take your first dividend, ideally before, so that you register on time. Also when you receive a letter from HMRC, when you have other income such as rent or capital gains, when your income approaches £100,000, and before the tax year ends on 5 April.
