HM Revenue and Customs complaints
Complaining to HM Revenue and Customs
You can complain about how HMRC has dealt with your tax credit, child benefit or guardian’s allowance claim or with your national insurance credits or contributions, online using a Government Gateway account, by telephone or in writing (see ). If you are not happy with the initial response, ask HMRC to review your complaint. The review should be carried out by a different customer service adviser, who will give you HMRC’s final reply to your complaint.
If you are not happy with HMRC’s final reply, you can ask the Adjudicator to look into it and recommend appropriate action.
Complaining to the Adjudicator
The Adjudicator’s Office can investigate complaints about the way in which HMRC deals with tax credits, child benefit and guardian’s allowance. Complaints can be made about delays, staff behaviour, misleading advice or any other form of maladministration. The Adjudicator cannot, however, investigate disputes about matters of law. The Adjudicator can only investigate a complaint if you have first exhausted the HMRC internal complaints procedure. A complaint should be made in writing using the form available from or online at . A complaint should be made within six months of the final correspondence with HMRC.
The Adjudicator can recommend that compensation be paid, and HMRC should follow her/his recommendations in all but exceptional circumstances. If you are unhappy with the Adjudicator’s response to your complaint, you can ask your MP to put your complaint to the Ombudsman (see here). As well as looking at your complaint about HMRC, the Ombudsman may also look into the way in which the Adjudicator has investigated your complaint.
