Estimate dividend tax due after the £500 dividend allowance, split across basic (10.75%), higher (35.75%) and additional (39.35%) rate bands.
Dividends are taxed after all other income. The £500 dividend allowance shelters the first £500 of dividends from tax. Above that, the rate depends on which income tax band the dividends fall in:
Employment and other non-dividend income fills the lower bands first, pushing dividends into higher bands if applicable.
The dividend allowance is £500 for 2026/27 (reduced from £1,000 in 2023/24 and £2,000 previously). Dividends within the allowance are not taxed, but they still use up your basic or higher rate band when determining how much tax-free room remains.
