Investment Dividend Tax Calculator 2026/27

ISA tip: Dividends inside a Stocks & Shares ISA are completely tax-free — no dividend tax regardless of amount. Consider sheltering high-yield investments in your ISA allowance first. The 2026/27 ISA allowance is £20,000.

About investment dividend tax

When you hold shares or funds outside an ISA or pension, any dividends received count towards your taxable income. Your employment or pension income fills the tax bands first; dividends then sit on top. The £500 dividend allowance and any remaining Personal Allowance reduce the taxable amount before the relevant dividend rate is applied.

Frequently asked questions

• Are dividends from overseas shares taxed the same way?

  UK dividend tax applies to overseas dividends received outside an ISA or pension in the same way as UK dividends. You may also have had foreign withholding tax deducted at source — you can often claim relief against your UK tax bill via Self Assessment.

• Do I need to report investment dividends on Self Assessment?

  You must file Self Assessment if your total dividend income exceeds £1,000 in a tax year (or £500 if you are already required to file). HMRC cannot collect dividend tax through PAYE.

• Does this calculator handle fund distributions?

  This calculator treats all dividend income equally regardless of source. Note that some fund distributions may be classified as interest (not dividends) and taxed differently — check your fund documentation or annual tax certificate.
