Best accountants for landlords in the UK

Our verdict

For most UK landlords, a specialist property accountant will save more in tax than they cost in fees, particularly once Section 24, capital gains tax, and Making Tax Digital are part of the picture. The challenge is knowing what to look for, since the term "accountant for landlords" covers everything from a local bookkeeper charging a few hundred pounds per year to a dedicated property tax firm modelling incorporation scenarios across a multi-property portfolio. This guide explains what a landlord accountant actually does, when you genuinely need one, what it costs, and what questions to ask before signing up.

Do landlords need an accountant?

There is no legal requirement for a landlord to use an accountant. You can register for Self Assessment, record your rental income and allowable expenses, apply Section 24, and file your own tax return without any professional help. HMRC's online system is designed for this, and for a landlord with a single property, straightforward expenses, and no mortgage, it is entirely manageable.

The calculation changes quickly once complexity enters the picture. A second property introduces the question of how to allocate shared costs. A mortgage triggers Section 24, which works differently from the old interest deduction and can produce counterintuitive results when your taxable income approaches a higher rate band. A property held jointly with a spouse requires both to file. Selling a property means dealing with capital gains tax and a 60-day reporting deadline. An HMO brings licensing, utilities, and a more complex expense structure. Each of these layers is individually manageable, but a landlord dealing with several of them simultaneously is spending meaningful time on tax administration that may not be their strongest use of hours, and the cost of getting something wrong accumulates.

The other honest answer is that the UK property tax landscape has become considerably more complicated since 2015. Section 24 changed the tax treatment of mortgage interest for individual landlords. Stamp duty surcharges altered the economics of portfolio expansion. The abolition of the Furnished Holiday Let regime in April 2025 closed a route that some landlords had structured around. Making Tax Digital has now introduced quarterly reporting obligations for those above the income thresholds. The Renters' Rights Act, which came into force in May 2026, brings new compliance demands. Taken together, these changes mean there is more scope both for landlords to pay more tax than they should and for them to fall foul of requirements they may not be aware of. A good accountant handles both risks.

What does a landlord accountant actually do?

The most visible job is the annual tax return, completing the SA105 property income pages of your Self Assessment, applying the right reliefs, calculating the correct tax liability, and filing before the 31 January deadline. But a landlord accountant who only does this is not providing the full value available to you.

Year-round record-keeping support is important, particularly since Making Tax Digital came into force in April 2026. If your gross property income (combined with any self-employment income) exceeds £50,000, you are now required to keep digital records and submit quarterly updates to HMRC using MTD-compatible software. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028. Your accountant should either set up and maintain these records on your behalf, or at minimum help you select and configure compliant software and brief you on what each quarterly update should contain. Use our Making Tax Digital guide for landlords to understand exactly what the quarterly process involves, and our MTD calculator to check when your phase starts.

Tax planning, rather than tax compliance, is where a specialist earns the most. This means reviewing your overall income position, not just your rental income in isolation, and identifying the right combination of legitimate strategies to reduce your tax liability. Those strategies might include timing capital expenditure, making pension contributions to reduce taxable income, correctly identifying all allowable expenses for landlords, splitting property ownership between spouses to use both basic rate bands, or modelling whether incorporation into a limited company would improve your net position over a five-year horizon.

Capital gains tax advice is a specialist function in its own right. When you sell a property, you have 60 days from completion to calculate and pay any capital gains tax due. That clock starts the moment contracts complete. An accountant consulted after the fact can file the return. One consulted before can influence the structure of the transaction. For a higher-rate taxpayer, the CGT rate on residential property is 24%. Decisions about timing disposals across tax years, claiming available reliefs, and correctly identifying base cost and improvement expenditure can have a significant effect on the final liability.

For landlords considering whether to restructure their portfolio, particularly those affected by Section 24, a property accountant should be able to model both personal and limited company ownership using your actual figures. The right structure depends on your tax band, the size of your mortgage debt, your plans for the portfolio, your exit horizon, and a range of personal financial factors that a generic comparison cannot capture.

Section 24 and why it makes specialist advice more valuable

Section 24 of the Finance Act 2015 removed the right of individual landlords to deduct mortgage interest from rental income as an expense. In its place, landlords receive a 20% tax credit on the interest paid. For a basic rate taxpayer, the effect is neutral. For a higher or additional rate taxpayer, the impact can be substantial.

The reason specialist advice matters here is that Section 24 distorts the apparent income figure in ways that have consequences beyond the tax rate itself. Because mortgage interest is no longer deducted before calculating taxable income, your total income figure is artificially higher than your actual economic profit. This inflated figure can push you into a higher tax band, reduce or eliminate your personal allowance, and create child benefit charge implications, none of which may be immediately obvious when you look only at your rental income in isolation. A landlord accountant who works specifically in property will model all of these interactions with your actual numbers, not just the headline rate.

Section 24 only applies to individual landlords. Limited companies can still deduct mortgage interest in full against rental profits, which is why the question of incorporation has become a central part of the conversation for higher-rate taxpaying landlords. The analysis is not straightforward, however. Transferring properties from personal ownership to a limited company typically triggers stamp duty land tax and potentially capital gains tax unless specific reliefs apply. Mortgage rates for limited company buy-to-let are generally higher than for personal ownership. Profit extraction through dividends or salary adds another layer of tax to model. For some landlords at some portfolio sizes, incorporation makes clear economic sense. For others, it does not. Only a detailed analysis using your specific figures produces a reliable answer.

What to look for in a landlord accountant

The most important question is whether the accountant specialises in property or works across multiple sectors. Property tax is complex enough that a generalist may handle your compliance correctly without identifying the planning opportunities available to you. Section 24, CGT on residential property, the mechanics of incorporation relief, the rules around furnished holiday lets (now abolished), the interaction between rental income and the tapered personal allowance, these are areas where genuine expertise is concentrated in firms that work exclusively or predominantly with landlords and property investors.

Ask whether they use and understand your chosen MTD-compatible software. If you are already using August to manage your rental records, open banking, and quarterly submissions, an accountant who is familiar with the platform can pull your quarterly figures directly without you having to translate between systems. If they insist on a different software workflow, understand whether that means duplicating data entry or whether there is a clean data handoff.

Ask whether their fees are fixed or hourly. Most reputable landlord accountants now quote fixed annual fees rather than billing by the hour. Fixed fees make budgeting predictable and remove the incentive to defer questions because you are worried about the cost. Typical fee ranges for a Self Assessment covering a single buy-to-let property run from around £300 to £800 per year. Landlords with multiple properties, more complex affairs, or a limited company structure should expect to pay £1,000 to £3,000 or more depending on the scope of work. These figures are a starting point: what matters is whether the fee is proportionate to the value delivered, not whether it is low in absolute terms.

Ask what their process is for capital gains events. The 60-day reporting deadline for residential property disposals is easy to miss, particularly if completion happens while your accountant is working on other clients' year-end filings. A firm with a clear intake process for disposal notifications, so that CGT calculations begin immediately on completion, not in January, is significantly more useful than one that treats a property sale as part of the annual return cycle.

Check their regulatory status. Accountants in the UK are not required to be members of a professional body, but a chartered or certified accountant regulated by the ICAEW, ACCA, or CIOT provides a level of professional accountability and complaints procedure that an unregulated bookkeeper does not. For any accountant giving tax advice, CIOT membership (Chartered Institute of Taxation) is the relevant qualification for tax-specific work.

When is the right time to bring in an accountant?

The honest answer is earlier than most landlords do. Many self-managing landlords handle their own tax for the first year or two and seek an accountant only when something goes wrong, when they acquire a second property and the complexity increases, or when they receive an HMRC inquiry. Each of these is a more expensive entry point than appointing someone at the start.

The situations where specialist input is most clearly warranted are: when your rental income is approaching a tax band boundary, because marginal decisions on allowable expenses or pension contributions can make a meaningful difference; before you sell a property, for the CGT planning window discussed above; before you buy an additional property, to understand stamp duty implications and whether your portfolio structure remains optimal; and at the point when Making Tax Digital obligations begin, because setting up the right digital record-keeping workflow at the outset is considerably less painful than retrofitting it after several quarters of quarterly submissions have already been filed. Our guide to how rental income is taxed in the UK is a useful foundation to read before your first accountant conversation, so that you arrive with a clear understanding of the basic mechanics.

How August works alongside your accountant

August is not an accountant and does not replace one. What it does is maintain the digital records that your accountant needs and that HMRC now requires under Making Tax Digital, automatically, as a by-product of managing your property day-to-day.

Open banking, regulated by the FCA and powered by Plaid, connects directly to your bank account and automatically matches incoming rent payments to the correct tenancy. Every payment is logged in real time, with a complete history per property available at any point. Expenses are recorded as they occur and categorised against HMRC-recognised allowable expense types, including the correct treatment of mortgage interest under Section 24. The result is that when your accountant needs your quarterly income and expense figures, whether to prepare your MTD update or your annual return, they are already there, clean and categorised, rather than being reconstructed from bank statements and receipts at year-end.

For landlords submitting quarterly MTD updates themselves, August compiles the summary figures from your digital records and allows submission directly to HMRC. For landlords using an accountant to file on their behalf, the same figures are available for your accountant to review and submit, removing the administrative step of gathering and reconciling records at each quarterly deadline. Use the rental income tax calculator to estimate your tax position at any point in the year, with Section 24 applied correctly.

The compliance features, certificate tracking, renewal reminders, document storage for Gas Safety certificates, EICRs, EPCs, and tenancy agreements, provide the record of active property management that matters if you are ever supporting an incorporation analysis or discussing your landlord status with HMRC.

The bottom line

A good landlord accountant is most valuable when they are doing more than filing a tax return. The landlords who get the most from specialist advice are those who use their accountant as a planning resource throughout the year, consulting before disposal decisions, reviewing their portfolio structure as tax rules change, and ensuring their digital record-keeping infrastructure supports both MTD compliance and accurate annual reporting.

The right accountant will understand Section 24 and its portfolio-level implications, have a clear process for time-sensitive CGT events, work with or alongside MTD-compatible software, and charge fixed fees that make the relationship predictable. For most landlords with two or more properties, or with a mortgage, the fees will be recovered many times over in correctly claimed expenses, avoided penalties, and tax planning that a generalist would not identify.

August keeps your records in order throughout the year, so that when you sit down with your accountant, the numbers are already there.
