Want to maximise your rental profits while avoiding costly tax mistakes?
Understanding UK landlord tax rules is essential in 2025 — especially with major changes such as the abolition of Furnished Holiday Let (FHL) tax benefits and the phased rollout of Making Tax Digital for Income Tax.
This guide explains how property is taxed in the UK, whether you’re buying, letting, or selling, and outlines practical strategies to stay compliant and reduce your tax bill.
Types of Property Investments and How They’re Taxed
There are three main types of residential property investments in the UK, each with different tax implications:
- Buy-to-Let (BTL) properties
- Furnished Holiday Lets (FHLs) (until April 2025)
- Second homes
Buy-to-Let Properties
Buy-to-let properties are purchased primarily to generate rental income and long-term capital growth.
Taxes Payable on Buy-to-Let Properties
Income Tax on Rental Profits
You pay Income Tax on rental profit, not turnover. This is rental income minus allowable expenses.
Income tax rates (2025/26):
- £12,571 – £50,270 → 20%
- £50,271 – £125,140 → 40%
- Over £125,140 → 45%
Rental profits must be declared on your Self Assessment tax return.
Mortgage Interest Relief
Individual landlords can no longer deduct mortgage interest from rental income. Instead, they receive a 20% tax credit on mortgage interest costs.
Limited companies can still deduct mortgage interest in full as a business expense.
Capital Gains Tax (CGT)
If you sell a buy-to-let property, CGT may apply to the gain.
CGT rates (from 6 April 2025):
- 18% for basic-rate taxpayers
- 24% for higher- and additional-rate taxpayers
CGT must usually be reported and paid within 60 days of completion.
Inheritance Tax (IHT)
Buy-to-let properties form part of your estate for IHT purposes. If your estate exceeds the nil-rate bands, IHT at 40% may apply.
Furnished Holiday Lets (FHLs): Changes from April 2025
From 6 April 2025, the special FHL tax regime is abolished.
What’s Changing?
- No capital allowances on fixtures and fittings
- No Business Asset Disposal Relief
- Profits taxed like standard rental income
- Occupancy tests no longer relevant for tax
Impact for Landlords
Many FHL owners will face higher tax bills and may need to reconsider pricing, ownership structure, or long-term strategy.
Second Homes
Second homes are properties that are not your main residence.
Key tax points:
- Rental income taxed under standard landlord rules
- CGT applies on sale
- Partial Principal Private Residence (PPR) Relief may apply if you lived there previously
- Full value included for IHT
Tip: Renting a room in your main home may qualify for the Rent-a-Room scheme, allowing up to £7,500 tax-free.
Ownership Structures: How Landlords Can Reduce Tax
How you own property has a significant impact on tax.
Direct Personal Ownership
- Rental profits taxed at your marginal Income Tax rate
- Losses can only be offset against future rental profits
- Mortgage interest restricted to a 20% tax credit
Joint Ownership & Partnerships
- Income can be split between owners
- Useful where one owner is a lower-rate taxpayer
- Flexible income allocation for married couples and civil partners
Limited Companies
Many landlords now use companies due to:
- Corporation Tax rates of 19%–25%
- Full mortgage interest deduction
- Ability to retain profits in the company
However:
- Selling property may trigger double taxation
- Extracting profits personally can incur dividend tax
Professional advice is essential before incorporating.
Taxes When Buying or Selling Property
Stamp Duty Land Tax (SDLT)
Rates for England and Northern Ireland:
- 0% on first £125,000
- 2% on next £125,000
- 5% on next £675,000
- 10% on next £575,000
- 12% above that
Second homes incur a 5% surcharge.
Annual Tax on Enveloped Dwellings (ATED)
Applies to companies owning UK residential property worth £500,000+.
- Annual charge depends on property value
- Exemptions exist for commercial letting
- ATED returns must still be filed to claim exemption
Capital Gains Tax Allowable Deductions
You can reduce CGT by deducting:
- Legal fees
- Estate agent fees
- SDLT paid on purchase
- Capital improvement costs (not repairs)
Principal Private Residence (PPR) Relief
If the property was once your main home:
- Relief applies for periods of occupation
- Final 9 months of ownership usually qualify
What’s Changing for Landlords Next?
Making Tax Digital (MTD)
- From April 2026: landlords with £50,000+ income must submit quarterly digital updates
- From April 2027: threshold reduces to £30,000
- Annual Self Assessment replaced by digital reporting plus a Final Declaration
Early preparation is strongly advised.

- Plan ahead for Inheritance Tax
- Keep accurate, digital records
- Seek professional advice when scaling your portfolio
