How the numbers shift across typical situations for this calculator:
| Scenario | Dividend tax | Dividends plus tax figure |
|---|---|---|
| 8.75% of £10,000 (basic, £875) | $875.00 | $10,875.00 |
| 33.75% of £10,000 (higher rate) | $3,375.00 | $13,375.00 |
| 39.35% of £10,000 (additional rate) | $3,935.00 | $13,935.00 |
| 8.75% of £5,000 | $437.50 | $5,437.50 |
How This Calculator Works
Subtract your annual dividend allowance from your total dividends, enter the taxable remainder, and choose the rate for your tax band (8.75%, 33.75%, or 39.35%). The calculator shows the dividend tax due; subtract it to get the net. Dividends are taxed on top of your other income, so the band — and therefore the rate — depends on your total income for the year.

Rate is the tax or tip percentage applied to the amount
Worked Example
At the basic rate of 8.75% on £10,000 of taxable dividends, the dividend tax is £875, leaving £9,125. UK dividends benefit from a tax-free dividend allowance each year; only dividends above it are taxed. The rate then depends on which Income Tax band the dividends fall into once stacked on top of your other income: 8.75% in the basic-rate band, 33.75% in the higher-rate band, and 39.35% in the additional-rate band. Dividends within an ISA are entirely tax-free and don't count.
Key Insight
Dividend taxation is a common issue for UK investors and company directors, and a few rules drive the bill. The tax-free dividend allowance comes first: each year a set amount of dividends is tax-free (this allowance has been cut sharply in recent years), and only dividends above it are taxable — so enter the amount over the allowance here. The rate then depends on your band, because dividends are treated as the top slice of income: you add your dividends on top of your other taxable income (salary, etc.), and the parts falling in the basic, higher and additional bands are taxed at 8.75%, 33.75% and 39.35% respectively. This means a single dividend can straddle two bands — part taxed at 8.75% and part at 33.75% — which this calculator doesn't split, so for a straddling case compute each portion separately. Dividend rates are deliberately lower than the equivalent rates on salary, which (together with National Insurance differences) is why owner-directors often take a small salary plus dividends — though the gap has narrowed as the allowance shrank and rates rose. Crucially, dividends inside an ISA or pension are completely tax-free and don't use the allowance or count toward your bands, so sheltering dividend-paying investments in an ISA is the simplest way to avoid the tax entirely. Dividends are reported via Self Assessment (or, for smaller amounts, sometimes collected through a tax-code adjustment). This calculator shows the tax on the taxable dividends at the band rate you choose and the net you keep; for an exact figure, deduct the dividend allowance first, and split the dividends across bands if they cross a threshold.
Frequently Asked Questions
How is UK dividend tax calculated?
Deduct the tax-free dividend allowance from your dividends, then tax the rest at your band rate. At 8.75% (basic rate) on £10,000 of taxable dividends, the tax is £875, leaving £9,125. The rate depends on which Income Tax band the dividends fall in once added on top of your other income.
What are the dividend tax rates?
8.75% in the basic-rate band, 33.75% in the higher-rate band, and 39.35% in the additional-rate band. Dividends are stacked on top of your other income to decide the band, so a single dividend can be taxed partly at one rate and partly at the next if it crosses a threshold.
What is the dividend allowance?
A set amount of dividend income each year that's tax-free, regardless of your band. Only dividends above it are taxed. The allowance has been reduced significantly in recent years, so more investors now pay dividend tax. Enter the amount above the allowance into this calculator.
Are dividends in an ISA taxed?
No — dividends from investments held in an ISA (or a pension) are completely tax-free. They don't use your dividend allowance and don't count toward your Income Tax bands. Sheltering dividend-paying shares and funds in an ISA is the simplest way to avoid UK dividend tax altogether.
Why do company directors take dividends?
Because dividend tax rates are lower than the rates on salary, and dividends don't attract National Insurance the way salary does. Owner-directors often take a small salary plus dividends to reduce the overall tax and NI bill — though the advantage has narrowed as the dividend allowance shrank and rates rose.

Methodology & Review
The tax is the band rate applied to taxable dividends (those above the dividend allowance); the total here is the dividends plus the tax figure so the tax (chargeAmount) and net dividend are easy to read off. It applies a single band rate and does not deduct the dividend allowance for you or split dividends that straddle two tax bands.
