Tax Credits: Adjudicator
This section of the website explains how to take a complaint to the Adjudicator once the HMRC internal complaints procedure has been exhausted.
If the claimant is still unhappy after going through the Tier 1 and Tier 2 complaints procedures, the case can be referred to the Adjudicator who is independent of HMRC and tries to find solutions by mediation or by making formal recommendations. The current Adjudicator is Helen Megarry.
The Adjudicator publishes a leaflet called: AO1 The Adjudicator's Office for complaints about HM Revenue & Customs and the Valuation Office Agency which gives a useful explanation of the process.
Other leaflets about complaints to the Adjudicator's Office can be found on the Adjudicator's website.
The Adjudicator's Office now requires their own signed authority from the claimant before they will deal with any complaint from someone acting on behalf of the claimant. The authority form is available on the Adjudicator's website. This authorisation is independent of any completed TC689 which may have already been provided to HMRC.
The Adjudicator’s website states that they expect complaints to be brought to them within 6 months of the date of last response from HMRC (This will be the Tier 2 response).
