UK Landlord Tax Relief 2026 – What’s Changed & What Still Works?

TL;DR: UK landlords are at a critical juncture in 2026. While current tax relief remains largely stable, with Section 24’s 20% mortgage interest credit still in place, two major changes are due. Firstly, Making Tax Digital (MTD) becomes mandatory from April 2026 for landlords earning over £50,000, and secondly, from April 2027, rental income will be taxed at new, higher rates (22%, 42% or 47%) compared to other income. These changes will significantly impact returns, meaning methodical, strategic planning is vital. This guide from our property tax experts outlines everything you need to know, including the finer details.

 

The UK property market rarely stands still, and if recent months have shown us anything, it’s that it changes relentlessly, making investments incredibly tricky to manage and time correctly. One notable widespread change that’s affected UK landlords everywhere concerns tax relief, to the point where understanding what’s available currently and what’s due to be introduced has become complex and more important to understand. This is especially concerning if you’re a property investor looking for a new opportunity or attempting to optimise your current position.

At IWN Accountancy, our specialist property tax experts in Bournemouth work closely with landlords across Dorset and the UK to navigate these complexities. This guide examines the current state of tax relief for landlords in 2026, highlights the major changes ahead, and provides clear strategies to help you optimise your position.

Tax Relief for Landlords in 2026: What’s Going On?

Despite numerous reforms over recent years, several key tax relief mechanisms remain available during the 2025/26 tax year.

• Landlords can still claim repairs, maintenance, insurance, estate agent fees, legal fees, accountant fees, paid utilities, ground rents, council tax, marketing and property-related travel costs as allowable expenses.
• Landlords can still take advantage of the tax-free £1,000 Property Allowance in rental income, automatically applying if gross income is below and no other expenses are claimed. If income exceeds this, the allowance can be claimed instead of actual expenses (if costs are low), but it cannot be used to create a tax loss.
• The Rent a Room Scheme stays unchanged at £7,500 per year tax-free (£3,750 for joint lettings) for letting furnished accommodation in your own home, providing a simple, tax-efficient income stream. Anything earned over this limit must be recorded via a Self-Assessment tax return.
• Section 24 restrictions on mortgage interest relief remain intact. Currently, individual landlords receive only a 20% tax credit on finance costs, rather than the full deduction previously available. This particularly impacts higher and additional rate taxpayers who cannot offset finance costs at the previously higher rates. Income tax on total rental income is applied to total rental income before finance costs are deducted.

Due in 2026: Making Tax Digital for Income Tax

From 6 April 2026, Making Tax Digital for Income Tax (MTD for ITSA) becomes mandatory for landlords with combined property and self-employment income exceeding £50,000. This means that landlords must now provide quarterly updates to HMRC (followed by a final declaration by 31 January) and transfer all records to digital and MTD-compliant software.

Some may be relieved at the reduced administrative workloads compared to extensive annual SA tax returns. There’s good reason to embrace this change; landlords can expect better financial oversight year-round, earlier spotting of potential tax issues, and less stress come year-end. Digital accounting solutions can streamline this process considerably.

The threshold decreases to £30,000 from April 2027 and £20,000 from April 2028. Property investors in Bournemouth and across Dorset should begin preparing now, as establishing good digital habits early prevents future complications.

April 2027 Property Tax Law Changes

While 2026 represents relative stability for tax relief rates, substantial changes are due to arrive in April 2027. As announced in the 2025 Autumn Budget, the following changes are afoot:

Separate Property Income Tax Rates

The most significant change is the introduction of separate, higher tax rates specifically for rental income.

From 6 April 2027, rental profits will be taxed at:

• Property Basic Rate: 22% (currently 20%)
• Property Higher Rate: 42% (currently 40%)
• Property Additional Rate: 47% (currently 45%)

For the first time, rental income will be taxed more heavily than employment income or trading profits at every bracket. The government projects this will raise approximately £500 million annually from 2028-29 onwards.

Impact on Mortgage Interest Relief

From April 2027, mortgage interest relief for landlords will be calculated at the new property basic rate of 22%, a modest increase from the current 20%. However, this small improvement does little to offset the overall tax increase. As such, a higher-rate landlord will see their effective tax liabilities on rental profits increase from 40% to 42%.

Changes to Allowance Allocation

From April 2027, the Personal Allowance and other general reliefs will apply to employment, trading, or pension income first, before being set against property or savings income. This means landlords may find less Personal Allowance available to offset rental profits, potentially increasing tax liability and triggering additional charges.

How Have Property Tax Laws and Relief Rules Changed?

Consider this example:

• Pre-2017: Full mortgage interest deduction at marginal tax rate. A higher-rate taxpayer with £10,000 mortgage interest saved roughly £4,000 in tax.
• 2025/26: 20% tax credit on mortgage interest introduced. The same landlord now receives only £2,000 relief, a 50% reduction.
• 2027/28 and beyond: 22% tax credit on mortgage interest, but rental income taxed at separate, higher rates (22%, 42%, 47%). The overall tax burden increases further, with the Office for Budget Responsibility (OBR) acknowledging these measures may reduce rental supply and push rents upward.

How to Maximise Available Landlord Tax Relief

A Limited Company Structure

Limited companies aren’t subject to Section 24 restrictions and can deduct mortgage interest as a business expense before calculating Corporation Tax. From April 2027, when personal rental income faces higher rates, the tax differential between personal and corporate ownership widens further.

For higher-rate taxpayers with growing property portfolios, incorporating as a limited company can offer substantial savings. However, transferring existing properties triggers Capital Gains Tax (CGT) and Stamp Duty Land Tax (SDLT) as well. Our buy-to-let accountancy experts can model scenarios to determine if incorporation makes financial sense for you.

Income Splitting for Couples

Married couples and civil partners can restructure property ownership through a Deed of Trust and Form 17 to allocate rental income to the lower-earning partner, potentially reducing the overall family tax bill significantly. With higher property tax rates due in 2027, this may prove cost-effective.

Maximising Expense Claims

With increasing tax rates and decreasing relief, claiming every legitimate expense matters more than ever. Many landlords miss deductible costs including professional fees for estate planning, bookkeeping services, accountancy fees, bank charges, and mileage for property-related travel, and so on. Every pound of deductible expense becomes more valuable under the 2027 rates.

Strategic Timing Considerations

For landlords considering significant transactions, such as selling properties, making improvements, or restructuring ownership, timing also has considerable tax implications, which certainly doesn’t ease any underlying feelings of stress. There may be advantages to bringing rental income forward to 2026/27 or deferring major expenditure to be offset more efficiently under the new regime. Professional landlord tax advisers can help with this and provide tailored advice and guidance to avoid ambiguity.
