The Ultimate “Allowable Expense Checklist” (2026/27 Edition)
Welcome to the ultimate “cheat sheet,” property owners! As your Chartered Accountant, I know that the difference between a profitable year and a taxable headache often comes down to the expenses you didn’t know you could claim.
With Making Tax Digital (MTD) officially launching in April 2026 for landlords with a combined income over £50,000, the stakes for accurate record-keeping have never been higher. HMRC isn’t just looking for your totals anymore; they’re looking for your digital proof.
Here is your customized checklist, categorized by the type of property you manage, to ensure you never miss a deduction.
🏠 For Single-Let (Standard Residential)
Best for: Long-term tenancies in houses or flats.
-
[ ] Letting Agent Fees: Full management, tenant-finding, and inventory fees.
-
[ ] Landlord Insurance: Buildings, contents, and rent guarantee insurance.
-
[ ] Safety Checks: Annual Gas Safety (CP12), EICR (every 5 years), and EPC.
-
[ ] Maintenance: Redecorating between tenancies, fixing leaks, and boiler servicing.
-
[ ] Replacement of Domestic Items: Like-for-like replacement of sofas, carpets, and white goods (since the FHL regime was abolished in 2025, this is now the standard for all).
-
[ ] Ground Rent & Service Charges: Fully deductible for leasehold flats.
🏘️ For HMOs (Houses in Multiple Occupation)
Best for: Shared houses, student lets, and professional house-shares.

💻 For the “Kitchen Table” Landlord (Admin & Office)
Regardless of property type, don’t forget your “invisible” business costs.
-
[ ] Home Office Use: A proportion of your home heating, lighting, and broadband. (Note: The £6/week flat rate for employees changed in April 2026, but you can still claim a fair proportion for your rental business).
-
[ ] Professional Fees: My accountancy fees for your tax returns and MTD submissions!
-
[ ] Subscriptions: Property management software (essential for MTD compliance), Landlords’ Association fees (e.g., NRLA).

-
[ ] Postage & Stationery: Printing tenancy agreements and office supplies.
Comparison Table: 2025/26 vs. 2026/27
The tax rates for property income are officially separated from April 2027, but for the 2026/27 tax year, the main change is the MTD Mandation.
| Category | 2025/26 Tax Year | 2026/27 Tax Year |
| Mortgage Interest | 20% Tax Credit | 20% Tax Credit |
| Personal Allowance | £12,570 | £12,570 |
| MTD Reporting | Optional (Pilot) | Mandatory (If income >£50k) |
| FHL Status | Abolished (Standard rules apply) | Abolished (Standard rules apply) |
| Basic Rate Tax | 20% | 20% |
⚠️ A Final Note on Section 24
Remember, your mortgage interest is not an allowable expense that reduces your taxable profit. Instead, you get a tax credit equal to 20% of your interest.
Example: If your rental profit is £20,000 and your mortgage interest is £5,000, you pay tax on the full £20,000 first, then subtract £1,000 (20% of £5k) from the resulting tax bill.
