My tenants recently moved out and I am currently doing some work on the flat to make it in good shape to re-let the property. I am due to pay the second half of my self assessment (due end of July for 2024-2025). The expenses incurred are within the last 2 weeks to which I have receipts etc. can I use these to offset my tax bill to hmrc or do the expenses need to be for the 2025-2026 tax year. Thanks
