Tax credits: payment enquiries

Call or write to HMRC if you have had a 'notice to pay' an overpayment of tax credit and cannot pay the full amount.

Phone

Call HMRC if you’re finding it hard to repay a tax credit overpayment — you may get more time. You’ll need your tax credit reference number.

If you have already been contacted by HMRC or a debt collection agency acting on their behalf, contact them using the details they’ve given you.

Telephone: 0345 302 1429

Opening times: Monday to Friday, 8am to 5pm. Closed bank holidays.
