Question to the HM Treasury:

To ask the Chancellor of the Exchequer, on how many occasions a repayment of overpaid tax to a customer who has submitted a voluntary self-assessment return been delayed by longer than (a) three, (b) six and (c) 12 months in the latest period for which data is available.

HMRC recognise that repayments are important for customers. They prioritise them and work hard to ensure they are processed as quickly and securely as possible.

Like any financial institution, HMRC are an attractive target for organised criminals who continually test their security and repayment controls. HMRC aim to balance ensuring prompt payments to eligible customers with effective revenue protection from fraudsters.

Voluntary returns are submitted by customers who are not required to file a Self Assessment return but choose to do so, often to reclaim overpaid tax. These cases can require additional manual checks, particularly where PAYE income is involved, to ensure repayments are not duplicated.

Because customers submitting voluntary Self Assessment returns are not required to file, these cases are not currently included separately in HMRC’s reported performance data. While these returns are worked and processed by operational teams, they fall outside the scope of published metrics and are therefore not counted in official service level reporting.

HMRC has communicated to agent communities that customers can help reduce delays by registering for Self Assessment before submitting a return. Additional staff have been deployed to reduce delays in processing voluntary Self Assessment repayment cases, particularly those requiring manual checks. Work is also underway to explore automation opportunities to improve processing times and reduce the number of customers affected by repayment delays.
