Dividend tax rates rose from 6 April 2026. Finance Act 2026 set the basic rate at 10.75% (up from 8.75%) and the higher rate at 35.75% (up from 33.75%), with the additional rate unchanged at 39.35%. Enter your dividend income and your other income (salary, pension, rental profit) and this calculator stacks everything across the bands, applies the £500 dividend allowance and the personal allowance taper above £100,000, and shows your 2026/27 bill next to what the same income would have cost in 2025/26.
Non-dividend income is taxed first, so it determines which bands your dividends fall into. Enter gross figures before tax.
Assumes the standard £12,570 personal allowance and no other reliefs or savings income. Scottish rates do not apply to dividends, so this works UK-wide.
