Hello there, property pioneers! I’m your friendly neighborhood Chartered Accountant, and today we’re diving into the wonderful (and occasionally head-scratching) world of UK property tax.
Whether you’ve just let out your first flat or you’re a seasoned pro with a small portfolio, the tax landscape is shifting faster than a tenant’s opinion on “feature wallpaper.” With the 2025/26 tax year upon us and major changes looming for 2026/27, let’s get you compliant, stress-free, and—dare I say—excited about your spreadsheets.
In the eyes of HMRC, you can only deduct expenses that are “wholly and exclusively” for the purpose of your rental business.
Think of it this way: If you buy a tin of paint for the rental’s hallway? Deductible. If you use half of it on your own living room? Pro-rata it! ### Common Allowable Expenses:
Letting agent fees: Those 10–15% management fees are fully deductible.
Insurance: Specialized landlord insurance, building, and contents.
Maintenance & Repairs: Fixing a leaky tap or replacing a broken boiler (see “Repairs vs. Improvements” below).
Professional Fees: Hey, that’s me! My accountancy fees are generally deductible.
Utilities & Council Tax: If you pay these during void periods.
One of the biggest traps for landlords is confusing a repair (revenue expense) with an improvement (capital expense).
| Feature | Repair (Deductible Now) | Improvement (Deductible later on sale) |
| Definition | Restoring to original condition. | Adding something new or upgrading. |
| Example 1 | Replacing a broken window (double glazing is fine). | Building a conservatory. |
| Example 2 | Repainting walls between tenancies. | Installing a high-end luxury kitchen. |
| Example 3 | Fixing a patch of damp. | Converting the loft into a bedroom. |
If you’re a higher-rate taxpayer, Section 24 is likely the bane of your existence. You cannot deduct your mortgage interest from your rental income before calculating tax. Instead, you get a 20% tax credit.
The Scenario: Meet Sarah. She earns £55,000 in her day job (Higher Rate) and gets £10,000 in rent. Her mortgage interest is £4,000.
Old Way: She’d pay tax on £6,000 profit.
New Way: She pays 40% tax on the full £10,000 (£4,000) but then gets a 20% credit on her £4,000 interest (£800).
Result: Her tax bill is £3,200. This is significantly higher than before!
Buckle up, because the government is making things “interesting.” While the Personal Allowance is frozen at £12,570 until 2031, property-specific rates are changing soon.
| Tax Year | Basic Rate | Higher Rate | Additional Rate |
| 2025/26 | 20% | 40% | 45% |
| 2026/27 | 20% | 40% | 45% |
| 2027/28 (Proposed) | 22% | 42% | 47% |
Note: From April 2025, the Furnished Holiday Let (FHL) regime is being abolished. If you have an Airbnb-style property, it will now be taxed just like a normal long-term rental. No more full interest deduction!
HMRC’s “Making Tax Digital” is the biggest shake-up in a generation. Gone are the days of one annual panic on January 31st.
From 6 April 2026: If your total business and property income is over £50,000, you must keep digital records and send quarterly updates to HMRC.
From 6 April 2027: This threshold drops to £30,000.
Imagine a graph of your year. Instead of one giant mountain of paperwork in January, you’ll have four small hills throughout the year. It’s actually better for cash flow—no more “Tax Bill Surprises!”
Separate Bank Accounts: Do not—I repeat, do not—mix your grocery shopping with your rental repairs. It makes your accountant cry.
Replacement of Domestic Items Relief: If you replace a sofa or fridge, you can claim the cost of the new one (minus any money you got for selling the old one).
Use the Property Allowance: If your total rental income is under £1,000, it’s tax-free and doesn’t even need to be reported! (Note: You can’t use this and claim expenses).
