Dividend Tax Calculator UK: Complete Guide to Calculate Your 2024-25 Tax Bill

Last Updated on: August 26, 2025

A dividend tax calculator is a digital tool that computes your UK dividend tax liability based on your total income, dividend receipts, and personal allowances. These calculators help shareholders, company directors, and investors determine exactly how much tax they owe on dividend payments received during the tax year.

What Is a Dividend Tax Calculator?

A dividend tax calculator automatically computes dividend tax owed to HMRC using current tax rates and allowances. It considers your total income to determine which tax band applies to your dividends, calculates available allowances, and provides the final tax due after accounting for dividend tax credits.
