The UK Property Tax Guide for Landlords
Rental income tax and Section 24
Since April 2020, individual landlords no longer deduct mortgage interest as an expense. Instead, they receive a 20% tax credit. For higher and additional-rate taxpayers, this is the single biggest change to landlord tax in a generation.
Allowable expenses
Revenue expenses are deductible in-year; capital expenses reduce future CGT. Getting the classification right is the difference between paying tax now and paying it never.
Capital Gains Tax on sale
Residential CGT rates are 18% for basic-rate taxpayers and 24% for higher-rate from April 2024. The annual exempt amount is £3,000. Returns and payment are due within 60 days of completion.
Stamp Duty on purchase
The 5% additional-property surcharge applies to every buy-to-let purchase in England and Northern Ireland. Wales and Scotland run LTT and LBTT with different bands.
Incorporation and the SPV question
The right structure depends on your marginal rate, LTV, growth ambition and exit strategy. Model incorporation costs — SDLT, CGT, refinancing — before pulling the trigger.
Making Tax Digital for Income Tax
MTD ITSA applies from April 2026 for landlords with gross rental income over £50,000, and April 2027 above £30,000. Quarterly submissions, digital records and MTD-compatible software are mandatory.
