How long does an HMRC tax refund take?

Full answer

HMRC issues tax refunds through several different routes depending on how the overpayment arose. Processing times vary significantly by route. **P800 tax calculation letter (automatic refund):** HMRC issues P800 letters after the tax year ends when their records show you overpaid (e.g. through PAYE with multiple jobs or emergency tax codes). Once you receive the P800: - **Online claim via Personal Tax Account:** refund typically arrives within **5 working days** - **If you do nothing:** HMRC sends a cheque automatically within **21 working days** of the P800 letter **Self Assessment (SA) tax return refund:** If your SA return shows a repayment due: - Processing time: typically **4–6 weeks** after submission - Faster if you bank account is registered with HMRC (BACS payment ~3–5 days after processing) - Slower during peak periods (January–March: SA deadline rush) **P50 form (in-year PAYE refund):** If you stop working mid-year and have overpaid PAYE, you can claim using a P50 (or via Personal Tax Account). Processing: typically **5–10 working days**. **R40 form (savings/investment income refund):** For refunds of tax deducted at source from savings or investments. Processing: typically **6–8 weeks**. **Cheque vs bank transfer:** - Bank transfer (BACS): fastest — 3–5 days once approved - Cheque: add 5–10 working days for postage and clearing **If it's taking too long:** - Log into your HMRC Personal Tax Account to check status - Use the HMRC app (available on iOS and Android) - Call HMRC Self Assessment helpline: 0300 200 3310 (allow 30–60 min wait) - HMRC's Complaints team handles cases outstanding beyond 6 weeks **Why refunds are delayed:** Common reasons include: security checks on first-time refund recipients, mismatch between P60/payslip data and HMRC records, outstanding returns from previous years, or system errors requiring manual review.
