Being a landlord in the UK comes with specific tax obligations. In 2026, several important rules are either newly introduced or fully in force, affecting how rental income is taxed, how it is reported to HM Revenue & Customs, and how much tax landlords may ultimately pay.
Understanding these rules is essential for compliance, accurate budgeting, and long-term property planning.
1. Income Tax on Rental Profits
Rental profits are taxed as income. This means landlords pay tax based on their overall taxable income, including rental profits, at their applicable income tax band:
- Basic rate
- Higher rate
- Additional rate
Rental income is not taxed separately. Instead, it is added to other income sources when calculating total tax liability.
Mortgage Interest Relief Restrictions
Mortgage interest can no longer be deducted in full from rental income before tax is calculated. This restriction, introduced under Section 24 and fully in place since 2020, continues unchanged in 2026.
Instead of deducting interest as an expense:
- Landlords receive a 20 percent tax credit on mortgage interest paid
- The credit is applied after tax has been calculated
This often results in higher taxable profits, particularly for higher-rate and additional-rate taxpayers.
2. Making Tax Digital for Landlords From April 2026
One of the most significant changes affecting landlords is the introduction of Making Tax Digital (MTD) for Income Tax.
Who Must Comply From 6 April 2026
Landlords must use Making Tax Digital if:
- Gross rental income plus any self-employment income exceeds £50,000
- The threshold is assessed before expenses
- Income was earned in the previous tax year
Affected landlords must use:
- HMRC-approved digital bookkeeping software
- Quarterly digital submissions
- A final end-of-year declaration using MTD software
This replaces the traditional annual Self Assessment process for those within scope.
What Making Tax Digital Means in Practice
Under MTD, landlords must:
- Keep digital records of income and allowable expenses
- Submit quarterly updates summarising figures
- Confirm final totals at the end of the tax year
The aim is to improve accuracy and reduce errors, but it also increases administrative responsibility.
Future MTD Thresholds
The MTD rollout continues beyond 2026:
- April 2027: Applies to landlords earning over £30,000
- April 2028: Expected to apply to landlords earning over £20,000
More landlords will be affected each year, making early preparation advisable.
3. Capital Gains Tax When Selling a Rental Property
Capital Gains Tax (CGT) is payable when a rental property is sold for more than its purchase price.
Residential Property CGT Rates in 2026
- Basic rate taxpayers: 18 percent
- Higher and additional rate taxpayers: 24 percent
These higher residential property rates remain in force through 2026.
The CGT annual exemption has been reduced in recent years, meaning more landlords are now liable to pay CGT when selling.
Some reliefs, such as letting relief, may still apply in limited circumstances, but these are far more restricted than in the past.
4. Stamp Duty Land Tax on Buy-to-Let Purchases
Landlords purchasing additional properties must pay Stamp Duty Land Tax (SDLT) with a surcharge.
SDLT Rules for 2025 and 2026
- A 5 percent surcharge applies to buy-to-let and second homes
- The nil-rate threshold has been reduced compared with previous years
This has significantly increased upfront purchase costs for landlords expanding their portfolios.
5. Other Important Tax Rules for Landlords
Property Allowance and Rent-a-Room Scheme
- A £1,000 property allowance is available for landlords with small rental income.
- You cannot claim both the allowance and actual allowable expenses
- The Rent-a-Room scheme allows up to £7,500 tax-free income when letting a room in your own home
Non-Resident Landlords
Landlords who live abroad but receive UK rental income are subject to special rules:
- Letting agents may deduct tax at source
- Registration with HMRC may be required to receive income gross
Failure to comply can lead to penalties or delayed repayments.
What Landlords Should Do in 2026
Landlords should take practical steps to remain compliant:
- Ensure digital bookkeeping systems are ready for MTD
- Understand the impact of restricted mortgage interest relief
- Plan for CGT if selling property
- Budget carefully for SDLT on new purchases
Final Advice
Landlord tax rules in the UK are increasingly complex and subject to change through future budgets. While this guide outlines the key tax considerations for 2026, professional advice from a qualified accountant is strongly recommended to ensure compliance and optimise your tax position.
