Whether you own a single buy-to-let property or manage a growing portfolio, understanding what a property accountant does can make a real difference to your finances. From filing your Self Assessment return to navigating complex rules around mortgage interest and capital gains, a property accountant handles the tax and accounting work that arises from owning, letting, and eventually selling UK property.
What Is a Property Accountant?
A property accountant is a qualified accounting professional who specialises in the tax and financial management of property ownership. Unlike a general accountant who works across various sectors, a property accountant has in-depth technical knowledge of property-specific legislation, including Section 24 mortgage interest restrictions, Stamp Duty Land Tax (SDLT), Capital Gains Tax (CGT), and Making Tax Digital (MTD) for Income Tax.
Their core role is to ensure landlords remain compliant with HMRC regulations while maximising all available tax reliefs and deductions, helping you keep more of what you earn from your properties.
Core Responsibilities of a Property Accountant
A property accountant covers several key areas of financial management for landlords:
Self Assessment and Tax Returns
The annual Self Assessment return (SA100 with SA105 property pages) forms the foundation of their work. They apply all allowable expenses correctly, calculate the Section 24 finance cost credit, and file any additional pages required such as SA108 for capital gains.
Bookkeeping and Record Keeping
Property accountants either manage bookkeeping directly or oversee records maintained through cloud accounting software such as Xero, QuickBooks, or FreeAgent. Accurate records ensure your rental income, mortgage payments, maintenance costs, and other property expenses are properly tracked and categorised.
Capital Gains Tax and 60-Day Returns
When a property is sold, a property accountant calculates the chargeable gain, applies the Annual Exempt Amount, determines the correct CGT rate (18% or 24%), and files the mandatory 60-day CGT return with HMRC. They reconcile this through the SA108 pages on your year-end return.
Making Tax Digital (MTD) Quarterly Updates
From 6 April 2026, landlords with gross rental income above £50,000 must comply with MTD for Income Tax. This means keeping digital records and submitting quarterly updates to HMRC, along with an End of Period Statement and a Final Declaration. A property accountant sets up compliant software, manages quarterly submissions, and ensures deadlines are met. The threshold will fall to £30,000 from April 2027 and £20,000 from April 2028.
Tax Planning and Advisory Work
Beyond compliance, property accountants provide forward-looking advice on Section 24 impact modelling, incorporation feasibility, spouse-split planning before disposal, disposal timing, and inheritance tax structuring.
Understanding Section 24 and Why It Matters
Section 24 is one of the most significant tax changes affecting UK landlords. Since April 2020, individual landlords can no longer deduct mortgage interest directly from rental income. Instead, relief is restricted to a 20% basic-rate tax credit applied to the lower of finance costs, property business profits, or adjusted total income.
For higher-rate taxpayers, this restriction significantly increases the effective tax burden on mortgaged properties. A property accountant models the exact impact of Section 24 on your specific portfolio, not just in general terms, and advises on strategies to mitigate its effects, including timing decisions, spouse splits, or incorporation.
Allowable Expenses Landlords Can Claim
One of the most practical benefits a property accountant delivers is ensuring all allowable expenses are captured correctly. Common deductible expenses include:
- Maintenance and repairs (not improvements)
- Letting agent fees and property management costs
- Landlord insurance premiums
- Utility bills paid on behalf of tenants
- Accountancy and professional fees
- Ground rent and service charges
- Replacement of domestic items (Replacement Domestic Items Relief)
Capital expenditure, such as building an extension or converting a loft, is not immediately deductible but can be used to reduce your Capital Gains Tax liability when you eventually sell the property.
When Do You Need a Property Accountant?
Not every landlord needs specialist professional support from day one, but there are clear trigger points where professional involvement pays for itself:
Growing Portfolio
When you move beyond a single property, the administrative load and interaction of expenses, income streams, and tax positions across multiple properties becomes genuinely complex.taxfile+1
Higher-Rate Taxpayer with Mortgage Interest
If Section 24 applies to your portfolio and you pay tax at the higher rate, the financial consequences of getting the mechanics wrong are significant.uklandlordtax+1
Planning a Sale or Disposal
The 60-day CGT reporting window is tight. Engaging a property accountant before exchange, not after completion, allows time for pre-sale spouse-split planning, disposal timing across tax years, and Principal Private Residence (PPR) relief calculations where applicable.
Considering Incorporation
Moving properties into a limited company involves complex CGT, SDLT, and Section 162 incorporation relief analysis. Getting it wrong could crystallise unnecessary tax charges.
Entering MTD Scope
Once your gross rental income exceeds £50,000, MTD for Income Tax applies from April 2026. A property accountant sets up the required digital workflow and manages your quarterly obligations.
Property Accountant for Company-Held Property
If your property portfolio is held within a limited company, the scope of your accountant’s work shifts considerably. They will handle:
- Corporation Tax returns (CT600) within 12 months of the accounting reference date
- Statutory accounts filed with Companies House within nine months of the year end
- ATED (Annual Tax on Enveloped Dwellings) returns for properties exceeding £500,000 in value
- Director’s loan account management and dividend planning
- PAYE if the company pays salaries
Companies are not subject to Section 24, which can make incorporation attractive for higher-rate landlords with significant mortgage interest. However, the decision involves weighing SDLT charges, dividend tax on profit extraction, and the long-term CGT position on disposal.
How Property Accountants Differ from General Accountants
A general accountant handles tax and financial work across many sectors. While perfectly capable for straightforward situations, they encounter property-specific rules only occasionally. A property accountant works with these rules daily and can plan around them rather than simply applying them.
The key areas where specialist depth shows include Section 24 modelling, the 60-day CGT reporting regime, SDLT planning (including the 5% additional dwellings surcharge), MTD for Income Tax compliance, and HMO or commercial property accounting. For a single basic-rate landlord with no mortgage and no plans to sell, a general accountant may suffice. For a mortgaged portfolio with higher-rate income, specialist knowledge typically repays its cost.

Frequently Asked Questions
Do I need a property accountant if I only own one property?
Not necessarily. A single basic-rate landlord with no mortgage and a straightforward position can often manage their own Self Assessment return. However, once complexity increases, such as a mortgage that triggers Section 24, a planned sale, or a move toward purchasing a second property, professional input adds real value.
What is the difference between a property accountant and a general accountant?
A property accountant specialises in property-specific tax rules including Section 24, the 60-day CGT reporting regime, SDLT surcharges, MTD for Income Tax, and incorporation relief. A general accountant applies these rules occasionally but rarely plans around them in the way a specialist does.
When did Making Tax Digital for Income Tax come into effect for landlords?
MTD for Income Tax became mandatory from 6 April 2026 for landlords with gross rental income above £50,000. The threshold falls to £30,000 from April 2027 and £20,000 from April 2028.
What allowable expenses can I claim as a landlord?
You can claim maintenance and repairs, letting agent fees, landlord insurance, utilities paid on behalf of tenants, professional fees, ground rent, and Replacement Domestic Items Relief on like-for-like replacements. Capital improvements are not immediately deductible but can offset CGT on disposal.
How does Section 24 affect my tax bill?
Section 24 restricts mortgage interest relief to a 20% basic-rate tax credit rather than a full deduction from rental income. For higher-rate taxpayers, this increases the effective tax burden on mortgaged properties considerably. A property accountant can model the exact impact on your portfolio and advise on mitigation strategies.
Should I hold my properties in a limited company?
This depends on your specific circumstances, including the size of your portfolio, your personal income tax rate, the level of mortgage debt, and your long-term plans for the properties. A property accountant can provide modelled analysis based on your actual numbers rather than a generic recommendation.
What qualifications should a property accountant hold?
Look for recognised professional qualifications such as ACA, ACCA, CIMA, or CTA, combined with demonstrable experience working with landlords and property investors. A genuine specialist will have a client base that is predominantly property-focused.
