UK Landlord Tax: The 2026 Guide

---

Being a landlord in the UK can be rewarding, but it comes with complex tax responsibilities. From rental income to property sales, understanding your tax obligations is essential for staying compliant and maximising your profits. This guide covers the key taxes, recent changes, and practical tips every landlord should know.

Landlords face several types of tax:

• Income Tax: On rental profits each year.
• Capital Gains Tax (CGT): When you sell a property.
• Stamp Duty Land Tax (SDLT): When you buy a property (higher rates for buy-to-let).
• Inheritance Tax: On property passed to heirs.
• National Insurance Contributions (NICs): Only if being a landlord is your main job or you run it as a business.

• Rental income is taxed at the same rates as other income. Your rental profit (rent minus allowable expenses) is added to your other income to determine your tax band.
• Tax bands for 2025/26: 
  • Personal Allowance: Up to £12,570 – 0%
  • Basic Rate: £12,571–£50,270 – 20%
  • Higher Rate: £50,271–£125,140 – 40%
  • Additional Rate: Over £125,140 – 45%
• From April 2027, property income tax rates will rise by 2 percentage points (22%, 42%, 47%). [simplybusiness.co.uk]

Property Allowance: The first £1,000 of rental income is tax-free. If your rental income is below this, you don’t need to declare it. Above £1,000, you must register for Self Assessment and file a tax return.

You can deduct certain expenses to reduce your taxable profit, including:

Letting agent fees and management costs

Legal fees for letting (not buying)

Accountant fees for rental accounts

Buildings and contents insurance

Ground rent and service charges

Council tax (when property empty)

Water, gas, electricity (if paid by you)

Advertising for tenants

Repairs and maintenance (not improvements)

Like-for-like replacement of domestic items (furniture, appliances)

Tip: Keep all receipts and records for at least 6 years

• Mortgage Interest Relief: Section 24 ChangesSince April 2020, you can no longer deduct mortgage interest from rental income before tax.
• Instead, you receive a 20% tax credit on mortgage interest paid.
• This change hits higher-rate taxpayers hardest, as they only get basic-rate relief.

CGT applies when you sell a rental property for a profit.

Rates for residential property:

18% for basic-rate taxpayers

24% for higher-rate taxpayers (reduced from 28% in 2024)

Annual CGT allowance: £3,000 per person (2025/26)

You must report and pay CGT within 60 days of completion

• SDLT surcharge on second homes and buy-to-let properties increased from 3% to 5% in 2025.
• Applies to purchases in England and Northern Ireland; similar increases in Scotland and Wales.

• If your rental income exceeds £1,000, you must register for Self Assessment and file a tax return by 31 January following the tax year.
• You’ll need to declare gross rental income, allowable expenses, and any other untaxed income.
• Making Tax Digital (MTD) is rolling out: from April 2026, landlords with property income over £50,000 must keep digital records and submit quarterly updates. The threshold drops to £30,000 in 2027 and £20,000 in 2028

•  Income tax rates on property income rise by 2% from April 2027.
• SDLT surcharge increased to 5%.
• Mortgage interest relief remains restricted to a 20% tax credit.
• MTD digital reporting becomes mandatory for many landlords.
• Furnished Holiday Lettings (FHL) special tax rules abolished from April 2025.
• CGT rates reduced for higher-rate taxpayers, but annual allowance cut to £3,000.

• Consider incorporation: Owning property via a limited company can offer tax advantages, especially for higher-rate taxpayers.
• Claim every allowable expense: Repairs, agent fees, insurance, and more.
• Keep digital records: Use MTD-compatible software to track income and expenses.
• Plan property sales: Time disposals to maximise CGT allowances and reliefs.
• Consult a tax adviser: Rules are complex and changing; professional advice can save you money.

• Register for Self Assessment by 5 October after the tax year you start letting.
• File online returns by 31 January; paper returns by 31 October.
• Late filing or payment triggers automatic penalties and interest

Landlord tax in the UK is complex and constantly evolving. Staying informed about the latest rules, claiming all allowable expenses, and planning ahead are essential for maximising your rental profits and staying compliant. With digital reporting and higher tax rates on the horizon, now is the time to get organised and seek expert advice if needed.
