Landlord Tax Update 2026/27: What UK Property Professionals Need to Know
The UK property tax landscape continues to evolve, with significant implications for landlords, letting agents, and property managers. As we approach the 2026/27 tax year, it’s crucial to stay informed about the latest changes to mortgage interest relief, Capital Gains Tax (CGT), and the expansion of Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA). This comprehensive guide provides actionable insights and practical advice to help you navigate the shifting tax environment and remain compliant.
Mortgage Interest Relief for Landlords: The Current State
Since the phased introduction of Section 24 of the Finance (No. 2) Act 2015, landlords can no longer deduct all their mortgage interest from rental income to reduce their tax bill. Instead, from April 2020 onwards, landlords receive a basic rate (20%) tax credit on finance costs, including mortgage interest, loans to buy furnishings, and fees. This restriction remains in place for the 2026/27 tax year, with no indication from HM Treasury of a reversal or further tightening as of June 2024.
How Does the Finance Cost Restriction Work?
- Landlords must declare their full rental income before deducting mortgage interest.
- Mortgage interest is no longer an allowable expense; instead, a 20% tax credit is applied to finance costs.
- This can push some landlords into higher tax brackets, as rental income is added to other income for tax purposes.
For example, a landlord with £15,000 rental income and £10,000 mortgage interest will pay tax on the full £15,000, then claim a 20% credit on the £10,000 interest (£2,000). Higher and additional rate taxpayers are particularly affected, as they no longer receive relief at 40% or 45%.
Practical Tips for Landlords
- Review your property portfolio’s profitability under the current regime.
- Consider incorporation, but seek professional advice due to potential Stamp Duty and CGT implications.
- Explore alternative finance structures or repayment strategies to minimise exposure.
- Keep detailed records of all finance costs for accurate tax returns.
Capital Gains Tax (CGT) on Property in 2026/27
CGT remains a key consideration for landlords selling investment properties. The 2023/24 tax year saw the annual exempt amount reduced to £6,000, and it is set to fall further to £3,000 from April 2024. There have been no further reductions announced for 2026/27, but landlords should remain vigilant for future Budget changes.
Current CGT Rates and Reporting Deadlines
- Residential property gains are taxed at 18% (basic rate) or 24% (higher/additional rate) from April 2024 onwards.
- Landlords must report and pay CGT within 60 days of completion using the UK Property Reporting Service.
- Private Residence Relief and Lettings Relief remain available in limited circumstances.
For more details, see the official HMRC guidance.
Action Points for Landlords Considering a Sale
- Calculate potential CGT liability before marketing your property.
- Gather evidence of allowable costs (improvements, legal fees, stamp duty, etc.).
- Consider timing your sale to maximise use of the annual exempt amount.
- Seek advice on reliefs and reporting obligations to avoid penalties.
Making Tax Digital for Landlords: MTD ITSA Expansion
Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is set to transform how landlords report rental income. From April 2026, landlords with gross property income over £50,000 per year must comply with MTD ITSA. Those with income between £30,000 and £50,000 will join from April 2027. The threshold for inclusion may be reviewed in future Budgets.
What Does MTD ITSA Require?
- Keep digital records of all property income and expenses.
- Submit quarterly updates to HMRC via approved software.
- File an end-of-period statement and final declaration annually.
MTD ITSA applies to individuals, partnerships, and trusts with UK property income. Non-resident landlords are also included if their UK property income exceeds the threshold.
Preparing for MTD ITSA: Practical Steps
- Assess your current record-keeping and accounting processes.
- Choose MTD-compliant software that integrates with your property management systems.
- Train staff and agents on digital record-keeping and quarterly submissions.
- Monitor HMRC updates and pilot schemes for the latest requirements.
Many landlords are turning to AI-powered inventory software to streamline compliance, reduce manual errors, and ensure accurate digital records for MTD ITSA submissions.
Other Key Tax Considerations for 2026/27
- Wear and Tear Allowance: Still replaced by the Replacement of Domestic Items Relief. Only actual costs of replacing furnishings are deductible.
- Stamp Duty Land Tax (SDLT): The 3% surcharge for additional properties remains in force. No major changes announced for 2026/27.
- Non-Resident Landlords: Must comply with the Non-Resident Landlord Scheme and MTD ITSA if above the income threshold.
- HMRC Compliance: Increased use of data analytics and cross-referencing with letting agent returns. Ensure all income is declared and records are robust.
Conclusion: Stay Ahead of Landlord Tax Changes
The 2026/27 tax year brings ongoing challenges for UK landlords, from the continued restriction of mortgage interest relief to stricter CGT rules and the digital transformation of tax reporting. Proactive planning, robust record-keeping, and the adoption of digital tools are essential to remain compliant and optimise your property business. Engage with professional advisers, stay updated with HMRC and ARLA Propertymark guidance, and review your portfolio strategy in light of these changes.
