Overpaid letting fees and refund

Dear HMRC, A letting agent charged me upfront for 12 months of letting fees which were paid in the 2022/23 tax year, the tenant then decided to end the tenancy after 2 months and the agent refunded the extra 10 months of fees that had been paid but the refund wasn't received by me until well into the 2023/24 tax year. My assumption, given I am using the cash basis, is that I would enter the full amount of the fee paid in the 2022/23 tax year as an allowable expense and then next year enter the amount of the refund I received in the 2023/24 tax year as taxable income in that year. I would be most grateful if you could please confirm if this is correct. Many thanks in advance

Hi,
Under the cash basis, the total amount of allowable expenses to be brought into account in calculating profits or losses are simply those paid during the year.

Thankyou.
