Managing property in England comes with more than maintenance costs and tenant agreements. Behind every buy-to-let investment or commercial property sits a complex web of tax obligations—and getting them wrong can be costly. Whether you own a single rental property or a growing portfolio, understanding your tax position is essential. That’s where a qualified property tax accountant makes all the difference. At Millbrook Accountancy Ltd, we work with landlords, property investors, and property businesses across the whole of England, providing specialist tax support that is accurate, proactive, and tailored to your circumstances. Based in London, our team brings together years of hands-on expertise to help property owners stay compliant, minimise liabilities, and make smarter financial decisions.
This guide covers everything you need to know about property tax accountant services—from the taxes that affect landlords to how professional support can protect and grow your investment.
What Taxes Do Property Owners in England Need to Pay?
Property ownership in England triggers several distinct tax obligations. Missing deadlines or misreporting income can lead to penalties from HMRC, so understanding what applies to you is the first step.
Rental Income Tax
If you receive rental income, you must declare it through Self Assessment. The amount of tax you pay depends on your total taxable income and your applicable Income Tax band:
- Basic rate taxpayers pay 20% on rental profits
- Higher rate taxpayers pay 40%
- Additional rate taxpayers pay 45%
Allowable expenses—such as letting agent fees, mortgage interest (subject to restrictions), repairs, and insurance—can reduce your taxable rental profit. A property tax accountant ensures you claim every legitimate deduction.
Capital Gains Tax (CGT) on Property
When you sell a property that is not your primary residence, Capital Gains Tax applies to the profit made. As of the 2024/25 tax year, the CGT rates for residential property are:
- 18% for basic rate taxpayers
- 24% for higher and additional rate taxpayers
CGT on property must be reported and paid to HMRC within 60 days of completion. Missing this deadline triggers automatic penalties.
Stamp Duty Land Tax (SDLT)
Stamp Duty Land Tax applies when you purchase property or land in England above certain thresholds. Buy-to-let investors and second-home buyers pay an additional 3% surcharge on top of standard SDLT rates—something that needs to be factored in when calculating the true cost of any acquisition.
Inheritance Tax (IHT) and Property
Property forms part of a person’s estate for Inheritance Tax purposes. With residential property values rising steadily across England, IHT exposure is a growing concern for property owners. Strategic planning—ideally started years in advance—can help mitigate this.
What Does a Property Tax Accountant Do?
A property tax accountant specialises in the specific tax obligations that apply to landlords, investors, and property businesses. The role goes well beyond filing a Self Assessment return once a year.
At Millbrook Accountancy Ltd, our property tax services include:
- Rental income tax returns — accurate preparation and submission of Self Assessment returns for landlords
- Capital Gains Tax reporting — calculating your gain, applying available reliefs, and submitting returns to HMRC within the required 60-day window
- SDLT advice — pre-purchase guidance to understand your full tax exposure before committing to a transaction
- Allowable expense reviews — ensuring you claim every deductible expense to reduce your tax bill legally
- Portfolio structuring advice — helping property investors consider whether holding property personally or through a limited company is more tax-efficient
- HMRC correspondence — dealing directly with HMRC on your behalf, so you do not have to
Should You Hold Property Personally or Through a Limited Company?
This is one of the most common questions property investors ask—and the answer is rarely straightforward.
Holding property through a limited company means rental profits are subject to Corporation Tax (currently 25% for profits above £250,000) rather than Income Tax rates of up to 45%. For higher-rate taxpayers with growing portfolios, this can represent a significant saving. However, transferring existing personally held properties into a company structure can trigger both CGT and SDLT, so the timing and circumstances matter enormously.
The right approach depends on:
- Your current Income Tax band
- The size and growth trajectory of your portfolio
- Whether you intend to reinvest profits or extract income
- Your longer-term estate planning goals
Millbrook Accountancy Ltd helps property owners model both scenarios clearly, so decisions are based on numbers rather than assumptions.
Common Mistakes Property Owners Make With Tax
Even well-organised landlords can fall into costly traps. Here are some of the most frequent issues we encounter:
- Claiming mortgage interest incorrectly — since 2020, individual landlords can no longer deduct mortgage interest as an expense. Instead, a 20% tax credit applies. Many landlords still misunderstand this change.
- Missing the 60-day CGT deadline — the window after property disposal is short. Missing it means an automatic £100 penalty, rising to £300 after six months.
- Failing to report all income — rental income from short-term lets, holiday properties, and subletting must all be declared.
- Overlooking the property allowance — individuals with gross rental income of £1,000 or less per tax year may be eligible for the property income allowance, meaning no tax is due.
- Not keeping adequate records — HMRC can investigate landlords up to four years back (or longer in cases of suspected fraud). Detailed, organised records are essential.

When Should You Hire a Property Tax Accountant?
The earlier, the better. Many landlords only seek professional advice after receiving a letter from HMRC or when they are about to sell a property. By that point, some planning opportunities have already closed.
Consider engaging a property tax accountant if:
- You have recently purchased your first buy-to-let property
- You are planning to expand your portfolio
- You are considering selling a property and want to understand your CGT position
- You are unsure whether to hold property personally or through a company
- You have received a compliance check or enquiry from HMRC
- You want to ensure your Self Assessment is accurate and complete
Frequently Asked Questions
What does a property tax accountant do for landlords?
A property tax accountant manages all tax-related obligations arising from property ownership. This includes preparing Self Assessment returns for rental income, calculating and reporting Capital Gains Tax on property disposals, advising on allowable expenses, and providing strategic advice on structuring property investments efficiently.
How much tax do landlords pay on rental income in England?
Landlords in England pay Income Tax on their rental profits at their marginal rate—20% for basic rate taxpayers, 40% for higher rate, and 45% for additional rate. Allowable expenses, such as maintenance costs and letting agent fees, reduce the taxable profit. Mortgage interest is no longer fully deductible; instead, a 20% tax credit applies.
What is the Capital Gains Tax deadline for property in England?
When you sell a residential property in England that is not your main home, you must report and pay any Capital Gains Tax owed within 60 days of the completion date. Failing to meet this deadline results in automatic penalties from HMRC.
Is it better to own a rental property personally or through a limited company?
There is no universal answer. A limited company pays Corporation Tax on profits (currently 25% for larger profits), which can be lower than higher-rate Income Tax. However, transferring existing property into a company can trigger Capital Gains Tax and Stamp Duty Land Tax. Millbrook Accountancy Ltd can model both options based on your specific financial situation.
Can Millbrook Accountancy Ltd help property owners outside London?
Yes. While Millbrook Accountancy Ltd is based in London, the firm provides property tax accountant services to clients across the whole of England. Services are available remotely via phone, email, and online platforms.
What expenses can landlords deduct from their rental income?
Landlords can deduct a range of allowable expenses, including letting agent fees, property maintenance and repairs, buildings and contents insurance, accountancy fees, and council tax (if paid by the landlord). Capital improvements—such as extensions—are generally not deductible as revenue expenses but may reduce a Capital Gains Tax liability on eventual sale.
