The time it takes to receive a stamp duty refund varies and depends on several factors, including the complexity of the case, the workload of HMRC, and the availability of the required documentation and evidence. On average, it can take anywhere from 5 weeks to 3 months to process a stamp duty refund claim and receive the refund payment.
Once HMRC have agreed to refund your overpaid stamp duty, you will get the refund within 5 days of the HMRC decision.
