Contractor tax calculator

UK contractor tax calculator

Estimate limited company take-home pay from contract income, expenses, salary, Corporation Tax, dividends, Income Tax, and National Insurance. Defaults use 2026/27 UK rates for England, Wales, and Northern Ireland.

Inputs

Use annual figures. Other taxable income is used to position the contractor salary and dividends in the tax bands, but it is not counted as contractor take-home.

Method

The calculator deducts salary, employer National Insurance, expenses, and company pension from company income, then estimates Corporation Tax and dividend extraction.

Limits

This is a simplified outside-IR35 limited company estimate. It does not cover VAT, the Flat Rate Scheme, Scotland tax bands, benefits, loans, associated companies, or accountancy advice.
