There has been no limit on the time allowed to dispute an overpayment before, and people could still dispute an overpayment even when their award had finished, and could still achieve success in getting it written off if the relevant proof was accessible.
But, in order to manage the number of disputes, and acquire tax credits system prepared for the move to Universal Credits, HMRC set to introduce a 3-month cut-off date for disputes.
According to this, you will be able to complete this if you send your dispute form in three months of either:
- the date on the primary letter or statement you received telling you that you have been overpaid
- the ‘decision date’ on your Annual Review notice
You can send it afterwards the deadline only in exceptional circumstances, let’s say you were in a hospital for the three months.
