Landlord Accounting in Wimbledon: Tax Advice for Serviced Accommodation & Buy-to-Let

If you own a buy-to-let or serviced accommodation property in London, specialist landlord accounting ensures you claim every allowable expense, stay compliant with HMRC, and structure your portfolio for long-term tax efficiency. With Making Tax Digital (MTD) for Income Tax now mandatory from 6 April 2026 for landlords earning over £50,000, the time to act is now — not at the January 31 Self Assessment deadline. GM Professional Accountants provides hands-on landlord tax advice to property investors in Canary Wharf, Ilford, Covent Garden, Wimbledon, Old Street and across Essex.

▶ Key Takeaways

MTD for Income Tax is mandatory from 6 April 2026 for landlords with gross income above £50,000 — and from April 2027 for those above £30,000. The Furnished Holiday Lettings (FHL) regime was abolished from 6 April 2025 — former FHL owners are now taxed as ordinary residential landlords. Section 24 mortgage interest restriction applies to individual buy-to-let landlords; limited company SPVs can still deduct mortgage interest in full. Serviced accommodation may trigger a VAT registration obligation once taxable turnover exceeds the VAT threshold — review your position now. Selling a rental property triggers a 60-day CGT reporting and payment deadline with HMRC from completion. From 6 April 2027, a new 2% property income surcharge takes effect — planning now reduces the impact on your portfolio.
Definition — Landlord Accounting

Landlord accounting is the specialist management of rental income, allowable expenses, tax returns, and compliance obligations — covering buy-to-let, serviced accommodation, HMOs, and limited company property portfolios — to minimise tax liability and satisfy HMRC reporting requirements.

⚠ 2026 / 2027 HMRC Changes Affecting Landlords: MTD for Income Tax requires digital quarterly reporting from 6 April 2026 (income >£50k) and April 2027 (income >£30k). A new 2% property income surcharge takes effect from 6 April 2027 under the Finance Act 2026. The FHL regime was abolished from 6 April 2025 — affected landlords should review allowable expense claims immediately. Read HMRC’s official MTD guidance →

What Is the Difference Between Buy-to-Let and Serviced Accommodation Accounting?

Buy-to-let (BTL) landlords rent on assured shorthold tenancy (AST) agreements, typically 6–12 months. Income is classified as rental income, reported via Self Assessment, and subject to Section 24 mortgage interest restrictions for individual landlords.

Serviced accommodation (SA) operates on short-term lets — think Airbnb, Booking.com, or corporate lets. Because services are provided alongside the property (cleaning, linen, utilities), SA is treated differently for VAT, income classification, and potentially CGT. Explore our Property Accountants in London service for a full overview of the UK property tax landscape.

What Tax Do Landlords Pay on Rental Income in 2026?

Rental income is added to your other income and taxed at your marginal rate: 20% (basic), 40% (higher), or 45% (additional). Individual landlords may no longer deduct mortgage interest directly — instead, a 20% basic rate tax credit applies. From 6 April 2027, a 2% property income surcharge takes effect under the Finance Act 2026, adding material cost to every portfolio.

Allowable expenses for both BTL and SA landlords include letting agent fees, repairs and maintenance, landlord insurance, ground rent and service charges, professional accountancy fees, advertising costs, and travel for property management. Capital improvements are not deductible against income but increase your base cost for Capital Gains Tax.

Self Assessment Deadline: The Self Assessment tax return for the 2025/26 tax year must be filed online by 31 January 2027. Any tax owed must also be paid by this date. Under MTD from 2026, landlords above the income threshold submit quarterly updates — the final declaration replaces the traditional annual return.

Should I Hold My Properties in a Limited Company or Personally?

This is one of the most consequential decisions a London landlord can make. Limited company SPVs (Special Purpose Vehicles) allow full mortgage interest deduction as a business expense, provide Corporation Tax rates currently at 25% on profits above £250,000, and offer inheritance planning flexibility. However, there are stamp duty costs on transfer, CGT on incorporation, and annual compliance costs.

Individual ownership retains simplicity but has become significantly less tax-efficient since Section 24. Higher rate taxpayers in particular should model both scenarios before buying their next property. GM Professional Accountants provides London SPV accounting services for landlords considering incorporation.

ConsiderationPersonal OwnershipLtd Company / SPV
Mortgage Interest Relief20% credit only (Section 24)Full deduction as business expense
Tax on Rental ProfitUp to 45% income tax + 2% surcharge (from 2027)25% Corporation Tax (profits >£250k)

What Are the Tax Rules for Serviced Accommodation in London After the FHL Abolition?

Prior to 6 April 2025, a Furnished Holiday Letting (FHL) that met HMRC’s qualifying conditions (available 210 days, let 105 days per year) enjoyed capital allowances, Business Asset Disposal Relief (entrepreneurs’ relief equivalent), and pension contribution treatment. Those advantages no longer exist. From 2025/26, SA income is taxed as ordinary property income under the same Section 24 restrictions as BTL.

However, serviced accommodation operators face additional considerations that standard BTL landlords do not:

VAT: If you provide services alongside accommodation (cleaning, linen changes, utilities), income may be treated as taxable rather than exempt. Once your taxable turnover exceeds the VAT registration threshold, you must register. London landlords operating at scale through Airbnb or Booking.com should review this carefully. Check HMRC’s VAT registration guidance here.

90-Day Rule (Greater London): Short-term lets of a property in Greater London are limited to 90 days per calendar year without planning consent under the Deregulation Act 2015. Exceeding this limit without permission carries significant penalties and may affect your tax position.

Business Rates vs Council Tax: Properties let as serviced accommodation for more than 140 days in a year may be assessed for business rates rather than council tax, affecting your cost base and relief entitlements.

Our team assists SA operators in Ilford, East London, Wimbledon, Old Street and across the wider London and Essex area. See our dedicated page on Accountants for Rent-to-Serviced Accommodation for a full guide to R2SA accounting.

What Does Making Tax Digital (MTD) Mean for London Landlords in 2026 and 2027?

MTD for Income Tax Self Assessment (ITSA) is now live. Landlords with combined gross income from property and self-employment over £50,000 must use MTD-compatible software and submit four quarterly updates per year from 6 April 2026. Those over £30,000 are brought into scope from April 2027.

Each quarterly submission covers a summary of income and expenses for that period. A final year-end declaration replaces the traditional Self Assessment return. Non-compliance carries automatic HMRC penalties.

GM Professional Accountants helps landlords across London and Essex set up MTD-compatible software (QuickBooks, Xero, FreeAgent), migrate from spreadsheets, and manage quarterly submissions on their behalf. For the full picture, read our guide: MTD Updates for London Landlords.

What Expenses Can a Buy-to-Let Landlord Claim in the UK?

Allowable revenue expenses reduce your rental profit before tax is calculated. Capital expenditure is not deductible against rental income but increases your property’s acquisition cost for CGT. The distinction matters enormously when HMRC investigates.

Expense CategoryAllowable (Revenue)?Notes
Letting agent / management feesYesFully deductible
Repairs and maintenanceYesRoutine upkeep only — not improvements
Landlord insuranceYesBuildings, contents, liability
Ground rent & service chargesYesLeasehold properties
Accountancy & professional feesYesTax return preparation and advice
Travel for property managementYesTo inspect or manage property only
Mortgage interestRestricted20% tax credit only for personal landlords
Replacement of domestic itemsYesLike-for-like replacements only (not initial purchase)
Extensions / conversionsNoCapital — adds to base cost for CGT
SA: Cleaning, linen, utilitiesYesDirectly attributable to rental activity

Do I Need to Pay Capital Gains Tax When I Sell a Rental Property in London?

Yes. Gains on the disposal of UK residential property are subject to Capital Gains Tax. As of 2025/26, the rates are 18% for basic rate taxpayers and 24% for higher and additional rate taxpayers on residential property gains (after the annual exempt amount, which stands at £3,000). For companies, Corporation Tax applies to gains.

Critical deadline: You must report and pay any CGT owed on a UK residential property within 60 days of completion. Missing this deadline triggers automatic HMRC penalties. Our team helps London landlords in Canary Wharf, Ilford, Wimbledon and Essex plan for CGT well in advance of any disposal.

How Does SDLT Affect London Landlords Buying Additional Properties?

Stamp Duty Land Tax (SDLT) on additional residential properties carries a 5% surcharge above the standard rates. First-time buyers purchasing a property intending to let it lose FTB relief if it is not their main residence. Limited company purchases are always subject to the surcharge regardless of whether it is the company’s first property acquisition.

Certain reliefs and refunds may be available — for example if you sell a previous main residence within three years. GM Professional Accountants reviews SDLT positions for landlords across London and Essex to ensure no overpayment occurs and any available refund is claimed.

Frequently Asked Questions: Landlord Accounting & Property Tax

Do I need an accountant for a single buy-to-let property in London?
There is no legal requirement, but with MTD now in force from April 2026 for higher-income landlords, Section 24 mortgage restrictions, and a new 2% property income surcharge from 2027, an accountant typically saves far more than their fee. Even a single property landlord benefits from correct expense claims, CGT planning, and Self Assessment filing.
What is the Self Assessment deadline for landlords in 2026/27?
The online Self Assessment deadline for the 2025/26 tax year is 31 January 2027. Tax owed must also be paid by this date. Under MTD from 6 April 2026, landlords above the £50,000 threshold must additionally submit quarterly digital updates throughout the year.
Is serviced accommodation income taxed differently from standard buy-to-let after the FHL abolition?
Since 6 April 2025, serviced accommodation is taxed as ordinary property income — the Furnished Holiday Lettings regime no longer exists. The Section 24 mortgage restriction now applies, capital allowances are no longer available (replaced by replacement of domestic items relief), and Business Asset Disposal Relief on disposal is gone. VAT exposure remains a distinct risk for SA operators.
Can I still claim capital allowances on my serviced accommodation property?
No — capital allowances for plant and machinery in SA were abolished alongside the FHL regime on 6 April 2025. From 2025/26, landlords use replacement of domestic items relief instead, which covers like-for-like replacements of furniture and appliances in a residential letting. Items already pooled before abolition continue to receive writing-down allowances.
How long do I have to report and pay CGT after selling a rental property?
You must report and pay CGT within 60 days of completion for UK residential property disposals. This is a strict HMRC deadline — missing it results in automatic late-filing penalties. GM Professional Accountants can prepare and submit your 60-day CGT return as soon as you exchange contracts.
Does running an Airbnb in London require planning permission?
In Greater London, you may let your property on a short-term basis for up to 90 days per calendar year without planning consent under the Deregulation Act 2015. Exceeding 90 days without planning permission is a breach of planning rules and may also affect your tax position, VAT status, and business rates assessment.
What software do London landlords need for Making Tax Digital?
MTD-compatible software includes Xero, QuickBooks, FreeAgent, and a number of HMRC-approved alternatives. The software must be able to generate quarterly digital submissions directly to HMRC. GM Professional Accountants helps landlords in London and Essex select, set up, and manage their MTD software as part of our landlord accounting service.
