Ask most limited company directors how their dividend tax actually gets worked out, and you'll usually get a rough guess rather than a real number. That's not surprising — between the Personal Allowance, the dividend allowance, and three separate tax bands, doing this by hand is genuinely easy to get wrong. A tax and dividend calculator takes the guesswork out, but it helps to understand what's actually happening behind the numbers first.
Here's how dividend tax works for 2026/27, and what you'll actually owe.
How Much Tax on Dividends Will You Pay?
From 6 April 2026, dividend tax rates went up — and many directors are still running their numbers on the old rates. The current rates are:
10.75% for basic-rate taxpayers
35.75% for higher-rate taxpayers
39.35% for additional-rate taxpayers (unchanged)
These sit on top of your Personal Allowance (£12,570) and the £500 dividend allowance — so your first £500 of dividend income each year is tax-free regardless of which band you're in. Everything above that is taxed at the applicable rate once your total income (salary plus dividends combined) is calculated.
Here's where people trip up: HMRC stacks your income before applying dividend rates. Salary counts first; then dividends sit on top of it. So a director on a £40,000 salary with £15,000 in dividends has a combined income of £55,000 — which pushes some of those dividends into the higher-rate band, not the basic one. Using a UK dividend tax calculator properly means entering your full income picture, not just the dividend figure in isolation.
How Much Dividend Is Tax-Free?
Just £500 — and that's it, regardless of your income level. It's worth noting that this allowance has shrunk considerably in recent years: it stood at £5,000 in 2017/18, then dropped in stages to today's £500. It applies once to all dividend income you receive in a year, whether from your own company, shares, or unit trusts — it doesn't reset per source.
Worked example: if you take £40,000 in dividends on top of a £12,570 salary, the first £500 is tax-free, and the remaining £39,500 is taxed at 10.75% — working out at roughly £4,246 for the year.
Salary vs Dividends: Getting the Split Right
This is where a lot of the real planning happens. Because dividends don't attract National Insurance the way salary does, many directors take a small salary — often close to the NI threshold — and draw the rest of their income as dividends. It's still generally more tax-efficient overall, even with the 2026 rate increase, but the gap has narrowed compared to a few years ago.
Running a dividend and salary tax calculator side by side, rather than looking at either figure in isolation, is really the only way to see the full picture — because the employer's National Insurance on salary (13.8%) and the interaction with your Employment Allowance eligibility both affect where the actual break-even point sits.
Do You Pay Corporation Tax on Dividends?
Not directly — but this is one of the most common misunderstandings we see. Dividends are paid out of profit after Corporation Tax has already been deducted, which means that profit effectively gets taxed twice: once at the company level, and again when it lands in your pocket as a dividend.
The problem: many directors calculate dividend tax as if it's the only tax on that money and end up underestimating their true tax burden. The fix: always work out your effective combined rate—Corporation Tax plus dividend tax together—rather than looking at either in isolation. It's the only way to genuinely compare taking money out as dividends versus salary versus leaving it in the company.
FAQs
1:Do I need to report dividend income to HMRC?
If your dividend income is over £10,000, you must file a Self Assessment return. Below that, you can usually tell HMRC after the tax year ends, and they'll collect the tax through your PAYE code or another arrangement.
2:Can I calculate dividend tax without an accountant?
You can use a calculator, but the accuracy depends entirely on entering your full income picture correctly—salary, dividends, and any other income all interact with the tax bands. Many directors find it faster and safer to get this checked professionally, especially around the April rate changes.
3:Are dividends from an ISA taxed?
No, Dividends received within an ISA or pension wrapper are completely free of dividend tax, and they don't count towards your £500 allowance or need to be reported through Self Assessment.
