If you feel that your overpayment was caused by TCO error, or a flawed system, or your award was too complicated to understand, print off and fill in the "Request to Reconsider Recovery of Overpayment" form, which is officially called a TC846 and is also known as an "RRR". Download form TC846
Don't spend too long filling it in though, because if and when your RRR fails, you will need to have 'new' details and information with which to re-appeal. So if you do it this way and it fails, you can just pad out and re-submit the details for the next stage. See here for some example TC846 content.
Send your completed form to this address:
Throughout all of this, keep full records of any contact with the Tax Credit Office; dates, times and content of telephone calls, copies of letters, etc.
Send everything by recorded delivery because the Tax Credit Office are now playing the 'we never received it' game and you may need proof of delivery at a later stage. Do not agree to meet with them, don't let them in if they turn up (tell them you are in RRR or dispute) and don't arrange repayment (ha!) until EVERYONE has failed your dispute.
If HMRC hassle you or affect your payments, complain that you are still in dispute and, as per their own legislation, they should not be seeking to recover until this process has been exhausted. You can use our sample "Dispute Status" complaint letter as a guide - just edit it to suit your circumstances.
This stage is only over if and when they write to inform you they have 'decided to not allow your request'. Before moving on to the next stage, respond back to them complaining if any issues have been left unaddressed / acknowledged and / or you feel their decision is unreasonable. You can use our sample "Failed Dispute" response letter - again, just edit to suit your circumstances.
If they start immediately hassling you for recovery before you are ready to respond, you can send them our "Pause Recovery" request letter.
