How Rental Income Tax Works in the UK
Landlords in the UK must pay Income Tax on profits from renting out property. Your tax liability depends on your total income, allowable deductions, and applicable tax bands. The tax is calculated on your rental profit after deducting allowable expenses, not on the gross rent received.
Personal Allowance
For the 2024/25 tax year, the personal allowance is £12,570. This means the first £12,570 of your combined income (rental profit plus other income) is tax-free. However, the personal allowance reduces by £1 for every £2 earned above £100,000.

Allowable Expenses for Landlords
You can deduct legitimate business expenses from your rental income to reduce your tax bill. Expenses must be “wholly and exclusively” for your rental business.
Common Allowable Expenses
- Letting agent fees and property management costs
- Buildings and contents insurance premiums
- Maintenance and repairs (but not improvements)
- Utility bills (water, gas, electricity if you pay them)
- Council tax and ground rents
- Services such as cleaning and gardening
- Legal fees for tenancy agreements under 12 months
- Accountancy fees for rental accounts
- Direct costs like advertising for tenants
- Vehicle costs for property management (mileage or actual costs)
Non-Allowable Expenses
- Capital improvements (extensions, conversions)
- Full mortgage payments (only interest qualifies with restrictions)
- Personal expenses unrelated to the rental business
- Initial furnishing costs (but replacements may qualify)
Replacement of Domestic Items Relief
From April 2016, landlords can claim relief for replacing furnishings, appliances, and kitchenware in residential properties. This includes beds, carpets, curtains, fridges, and similar items. You can only claim for replacements, not initial purchases. If the replacement is an upgrade, you can only deduct the cost of a like-for-like replacement.
Mortgage Interest Relief Changes
Significant changes to mortgage interest relief were phased in between April 2017 and April 2020. Since 6 April 2020, landlords cannot deduct mortgage interest costs from rental income before calculating tax.
Current Mortgage Interest Treatment
Instead of deducting mortgage interest as an expense, residential landlords now receive a tax credit worth 20% of their mortgage interest costs or 20% of their rental profit, whichever is lower. This means:
- Higher-rate (40%) taxpayers effectively lose relief on half their mortgage interest
- Additional-rate (45%) taxpayers lose even more relief
- Basic-rate (20%) taxpayers see no change in relief value
- The restriction applies to residential properties only
- Commercial property landlords still deduct interest as an expense
Property Allowance
The Property Allowance gives you £1,000 of tax-free rental income per year. If your rental income is £1,000 or less, you pay no tax and do not need to report it to HMRC.
Choosing Between Property Allowance and Expenses
If your rental income exceeds £1,000, you must choose between:
- Claiming the £1,000 Property Allowance: Simpler, no record-keeping required, but you cannot claim any actual expenses
- Claiming actual expenses: More paperwork, but beneficial if your expenses exceed £1,000
The calculator automatically recommends the best option based on your expenses. Generally:
- Claim the allowance if expenses are under £1,000
- Claim actual expenses if they exceed £1,000
- Consider mortgage interest restrictions when deciding
Calculating Your Rental Profit
Follow these steps to determine your taxable rental profit:
- Add all rental income: Include rent, service charges you receive, and payments for furniture use
- Deduct allowable expenses: Either use the £1,000 property allowance or claim actual expenses (but not both)
- Calculate rental profit: Rental income minus deductions equals your rental profit
- Add to other income: Combine rental profit with employment, pension, or other income
- Apply personal allowance: The first £12,570 is tax-free (subject to taper above £100,000)
- Calculate tax: Apply relevant tax rates to income above personal allowance
- Apply mortgage interest relief: Deduct 20% tax credit on residential mortgage interest (if applicable)
Multiple Properties
If you own multiple rental properties, treat them as one property business for tax purposes. Add all income together and all expenses together. Losses from one property offset profits from another. However, UK and overseas properties must be kept separate.
Common Questions
Do I need to register for Self Assessment?
Yes, if your rental income exceeds £1,000 per year (after the property allowance) or £2,500 if you are not already in Self Assessment. You must register by 5 October following the tax year in which you first had rental income to declare.
When is my rental income tax due?
Income tax on rental profits is paid through Self Assessment. Tax is due by 31 January following the tax year. For example, tax on 2024/25 rental income is due by 31 January 2026. You may also need to make payments on account.
Can I deduct my full mortgage payment?
No. Only the interest portion of mortgage payments qualifies for relief, and since April 2020, this is given as a 20% tax credit rather than a deduction. The capital repayment part of your mortgage is never tax-deductible.
What if my expenses exceed my rental income?
If allowable expenses are greater than your rental income, you make a loss. You can carry this loss forward to offset against future rental profits from the same property business. You cannot offset rental losses against other types of income like employment income.
Are repairs and improvements treated the same?
No. Repairs restore the property to its original condition and are allowable expenses. Improvements or enhancements add value or functionality and are capital expenses that cannot be deducted. For example, fixing a broken boiler is a repair; installing a new kitchen where none existed is an improvement.
Can I claim expenses for a property I rent to family?
Yes, but only if you charge a commercial rent. If you let to family or friends at below market rate (uncommercial let), expenses can only be deducted up to the amount of rent received. You cannot create a loss with an uncommercial let.
Does the Rent-a-Room Scheme apply?
The Rent-a-Room Scheme offers £7,500 tax-free income per year but only applies if you rent out a room in your main home while living there. It does not apply to separate buy-to-let properties. If you qualify and your rental income is under £7,500, you pay no tax and do not report it.
What records must I keep?
Keep accurate records of all rental income received and expenses paid. This includes rent books, receipts, invoices, bank statements, and mileage logs. Records must be kept for at least 5 years after the 31 January tax return deadline. HMRC can penalise inadequate record-keeping.
How does joint ownership affect tax?
If you jointly own a property with a spouse or civil partner, rental income is usually split 50:50 for tax purposes. However, if you own in unequal shares, you can declare beneficial interests and be taxed according to actual ownership proportions. For joint ownership with non-spouses, income is typically split according to legal ownership shares.

Scottish taxpayers may pay different amounts on the same rental profit due to these rate differences. The calculator accounts for your residency to provide accurate results.
