UK dividends are taxed separately from salary, with their own allowance and rates, and are treated as the top slice of your income. This calculator stacks your dividends on top of your other income for 2025/26 and applies the correct band rates.
How it works
After any unused personal allowance, the first £500 of dividends falls in the dividend allowance and is taxed at 0% (though it still occupies the band). Remaining dividends are taxed by the band they sit in once stacked on top of your other income: 8.75% in the basic-rate band (up to £50,270 total income), 33.75% in the higher-rate band (to £125,140), and 39.35% above that.
taxable dividends = dividends − unused personal allowance − £500 allowance
rate = 8.75% / 33.75% / 39.35% depending on the band the slice falls in
Example
With £30,000 of salary and £10,000 of dividends, the salary uses the personal allowance. After the £500 dividend allowance, £9,500 of dividends is taxable. Total income (£40,000) stays within the basic-rate band, so all £9,500 is taxed at 8.75% = £831.25, an effective rate of about 8.3% on the dividends.
Notes
Estimate only, not tax advice. Models 2025/26 dividend tax with the £500 allowance and 8.75% / 33.75% / 39.35% rates, stacking dividends on top of other income and tapering the personal allowance above £100,000. Dividends inside an ISA are tax-free and not counted here. Verify at gov.uk.
