Tax Credits: Adjudicator’s Office and Ombudsman’s reports

The Adjudicator’s Office investigates complaints about HMRC, and the Ombudsman’s office investigates complaints made against a wide range of Government departments including HMRC.

More information about the Adjudicator complaints process and about taking a case to the Ombudsman can be found in the tax credits guidance section of this website.

Adjudicator’s Office

Each year, the Adjudicator’s Office publishes a report which sets out the number of complaints dealt with (including tax credits) and the number that were upheld. The report also highlights key areas of concern as well as a series of case studies showing the outcome as well as the reasoning for each example.
