HMRC aim to turnaround SME R&D tax credit claims within 28 days. However, the length of time it takes for HMRC to review a claim will depend on the complexity of the claim, your accounts and the time of year.

After HMRC have processed and accepted your claim, they will notify you/us and if a repayment is due run a security check on the selected payment method. The actual payment will follow in about 7 days.
