You receive rent each month in your account. You pay the mortgage, cover repairs, and keep what remains. But that remaining amount may be different from the profit HMRC uses to calculate your tax.
Mortgage payments are often where the confusion starts. Some property costs reduce your taxable profit. Others qualify for a separate tax reduction, while some receive no income tax relief.
This guide covers personally owned residential lettings for the 2026/27 tax year. Properties held through a limited company follow different rules.
How much tax do landlords pay on rental income?
Your rental profit is added to your other taxable income. These include your salary, your pension, or earnings as a self-employed individual.
The Personal Allowance for 2026/27 is £12,570. The allowance applies to your total income and not an allowance for rent.
Income tax rates in England, Wales, and Northern Ireland are:
| Band | Rate |
| Basic rate | 20% |
| Higher rate | 40% |
| Additional rate | 45% |
With the standard allowance, higher-rate tax normally starts when income exceeds £50,270. Additional rate tax is charged on income over £125,140.
The personal allowance is reduced by £1 for each £2 of adjusted net income over £100,000. In Scotland, there are separate rates and bands for rental profits.
Basic rate taxpayer status from your job does not guarantee that your rental profit will be taxed at 20%. The extra income may take part of your earnings into a higher band.
Which rental expenses can you claim?
First look at the rent you have received before the agent takes out fees. After that, find the costs that are eligible for relief.
Common allowable expenses include:
- Letting agent and property management fees.
- Landlord insurance.
- Routine repairs and maintenance.
- Council Tax and utility bills you pay for the letting.
- Cleaning and gardening costs.
- Accountancy fees relating to the rental business.
Personal spending does not qualify. Where a bill covers both private and rental use, only the rental portion may be deductible.
Repairs and improvements have different treatment
Fixing a damaged roof will usually count as a repair. Building an extension is normally a capital improvement.
Capital improvements are not deducted from rental income. Keep the invoices, though, as qualifying costs may be relevant when calculating capital gains tax on a later sale.
Replacing a worn-out appliance may qualify for relief for domestic items. Buying furniture for the first time does not qualify under that relief.
Make sure to ask contractors to describe the work on their invoices. A bill that simply says “property work” gives you little detail when preparing your return.
How mortgage interest affects your tax bill
For individual residential landlords, mortgage interest is not subtracted when computing taxable rental profit.
Instead, qualifying finance costs may receive a basic-rate tax reduction. For 2026/27, that rate is 20%.
The calculation looks at the lowest of your qualifying finance costs, property profits after brought-forward losses, or adjusted total income above your personal allowance. For this purpose, adjusted total income excludes savings and dividends.
The reduction cannot create a tax refund. Finance costs restricted by the profit or income limits may be carried forward. Mortgage capital repayments do not qualify for this relief.
A rental income tax example
Imagine a landlord living in England. He gets £35,000 in salary. He also gets £15,000 from rent during the tax year 2026/27.
They pay £3,000 in running costs and £5,000 in qualifying mortgage interest. They have the personal allowance, no other income, and no other adjustments.
| Calculation | Amount |
| Annual rent | £15,000 |
| Allowable running costs | £3,000 |
| Taxable rental profit | £12,000 |
| Tax on rental profit at 20% | £2,400 |
| Mortgage interest tax reduction | £1,000 |
| Additional Income Tax from letting | £1,400 |
Their combined salary and rental profit is £47,000, so the rental profit stays within the basic-rate band.
After running costs, interest, and the additional tax, £5,600 remains. That figure is before any mortgage capital repayments or other spending.
This illustrates why taxable profit and cash left in the bank can differ. A landlord whose rental profit is in the higher-rate tax band might pay 40% on that profit while getting finance cost relief at 20%.
Can you use the £1,000 property allowance?
The eligible individuals can receive up to £1,000 in property income each tax year without paying tax on it. The allowance applies per person, not per property. If your gross property income exceeds £1,000, you may be able to deduct the allowance instead of actual expenses.
You cannot claim both against the same income. You also cannot use the property allowance alongside the residential finance cost tax reduction.
For instance, when the qualifying expense is £2,500, deducting those expenses would reduce profit more than a £1,000 allowance. the numbers before making your decision. Limitations include income from an employer or controlled business.
What if you rent out a room in your home?
The Rent a Room Scheme is separate. It can cover up to £7,500 a year from letting furnished accommodation in your home.
In case the income is shared by another person, then the threshold drops to £3,750. It is applicable in case of buy-to-let investment property in which one does not reside.
When do you need to tell HMRC?
If you have no tax to pay, that doesn’t always mean you don’t have to report to HMRC.
HMRC’s rental guidance requires a self-assessment return where rental income exceeds:
- £2,500 after allowable expenses.
- £10,000 before allowable expenses.
If your income is above the property allowance but below the thresholds for returns, please contact HMRC for instructions on how to report it. If you already submit a return, include taxable rental income on it.
For the 2025/26 tax year, the normal deadlines are:
| Action | Deadline |
| Notify HMRC that you need to file, where required | 5 October 2026 |
| Submit a paper return | 31 October 2026 |
| Submit an online return | 31 January 2027 |
| Pay the tax due | 31 January 2027 |
This period is for income earned in the tax year ending 5 April 2026. In case you miss the deadline for registration, contact HMRC immediately.
Allow for payments on account
Your first January payment can be larger than expected.
Where payments on account apply, you pay the previous year’s outstanding tax plus an advance towards the next year. A second advance is due in July.
For example, the first self-assessment bill of £2,000 would result in £3,000 being due in January and the other £1,000 in July if the total bill is within the payment-on-account system.
An exception to this would be where the bill is less than £1,000 or 80% of the tax has already been paid without self-assessment.
What changes under Making Tax Digital?
Some landlords now need to keep digital records and send quarterly updates through compatible software.
The starting date depends on qualifying income in an earlier tax year:
| Qualifying income | Relevant tax year | MTD start date |
| More than £50,000 | 2024/25 | 6 April 2026 |
| More than £30,000 | 2025/26 | 6 April 2027 |
| More than £20,000 | 2026/27 | 6 April 2028 |
Qualifying income usually includes money from property and self-employment before any costs are subtracted. It is not just the profit you make from renting out property. Exemptions can apply.
Individuals who fall under the rules will have to use compatible software for their record keeping and updates every quarter and yearly reporting. Ensure that you check your classification prior to the relevant date.
What happens with joint ownership or rental losses?
Married couples and civil partners living together are normally taxed equally on income from jointly owned property.
Where actual ownership and income rights are unequal, a valid declaration may allow taxation on those unequal shares. You cannot simply choose a different split on your tax returns.
Ordinary rental losses are generally carried forward against future profits from the same property business. They normally cannot reduce the tax on your salary.
Get your rental records ready before filing
Keep the rent statement, agent statement, invoices, and mortgage interest together. The total rent amount and the agent’s fee should be recorded separately, regardless of the net payment that the agent will make.
A monthly review helps you identify any missing invoices. You get a better estimate of how much money to set aside.
Check three things before filing your documents. Have you separated mortgage interest from capital repayment? Have you distinguished repairs from improvements? Have you included your other income when estimating tax?
For help with your rental income tax return, book a meeting with RMA Accountants LTD to discuss your records and circumstances.
