Tax credits calculator

You can only make a new claim for tax credits if you already get Child Tax Credit or Working Tax Credit.

If your circumstances change and you already receive tax credits, use the calculator to see how much you could now get in tax credits. The estimated figure is for a 4-week period.

Your tax credits will stop if you or your partner apply for Universal Credit. Check how tax credits and Universal Credit affect each other.
