Checked on GOV.UK on .

Estimate only, not tax advice. This uses the GOV.UK rates for the year you pick and only the figures you enter. It doesn't see your HMRC record, student loan, Marriage Allowance, pension or Gift Aid relief, savings, dividend or property income, or losses, and it isn't for limited companies. Your real refund or bill is what HMRC works out from your Self Assessment return. Your figures stay in your browser: nothing is sent or saved.

How much CIS tax are you owed back?
