Full answer
HMRC's processing time for Self Assessment tax returns varies depending on how you filed and when. Online returns (via HMRC online or commercial software): - Processing typically completes within 2 to 4 weeks during quieter periods. - Tax refunds are usually paid within 5 to 7 weeks of the return being received. - HMRC states it aims to process online returns within 15 working days during standard periods. - During peak filing season (January, just before the 31 January deadline), processing can slow to 6 to 8 weeks. Paper returns: - Paper returns generally take 10 to 12 weeks to process. - If you submitted a paper return close to the 31 October paper deadline, expect longer waits. - HMRC is actively discouraging paper filing and some taxpayers can only file online from 2024 onwards. How refunds are paid: - HMRC normally issues refunds directly to your bank account (provide bank details in your return or online account). - Without bank details on file, a cheque is sent to your registered address. - You can track the status of your return via your Personal Tax Account on GOV.UK. If HMRC needs more time: - You may receive a letter asking for more information -- reply promptly to avoid further delay. - HMRC can open a compliance check before issuing a refund if the return looks unusual. Chasing a delayed refund: - Wait at least 8 weeks from filing before contacting HMRC. - Use the online chat, personal tax account, or call 0300 200 3310. - If HMRC is late paying a refund, you may be entitled to repayment supplement (interest from HMRC).
