How to calculate dividend tax

Dividends sit on top of your other income and are taxed at their own set of rates after a small tax-free dividend allowance. Which dividend rate applies depends on the band your total income lands in.

The rule

Dividend tax = (dividends − dividend allowance) × the dividend rate for your income band

Do it automatically — Dividend tax

Step by step

  1. 1Add salary and other income to establish which band you are in.
  2. 2Subtract the dividend allowance from your total dividends.
  3. 3Stack the remaining dividends on top of your income and tax each slice at the matching dividend rate.

What trips people up

  • The dividend allowance uses up band space even though no tax is charged on it.
  • Dividends carry no social contributions, which is why owner-managers mix salary and dividends.

Common questions

Are dividends inside an ISA or retirement account taxed?

No — dividends inside a tax-sheltered account are outside this calculation entirely.

When is dividend tax paid?

Through self-assessment or your annual return, not at source.
