Best accountants for landlords in the UK: how to choose in 2026

Written by the August editorial team. Reviewed by Michael Doyle, ATT and qualified member of the Chartered Institute of Management Accountants. Last reviewed: June 2026.

Choosing an accountant for your rental property comes down to five things: genuine property tax specialism, a clear process for time-sensitive capital gains events, familiarity with Making Tax Digital and your record-keeping software, transparent fixed fees, and recognised professional regulation. The term covers everyone from a local bookkeeper filing a single Self Assessment return to a specialist firm modelling incorporation across a portfolio, so the right choice depends on how complex your affairs are. This guide explains what a landlord accountant does, when you genuinely need one, what it costs, and the questions worth asking before you sign up.

August does not have a commercial relationship with any accountancy firm, and has received no payment for any mention in this article. Our interest is in helping landlords understand how property tax and record-keeping fit together, because the quality of your records shapes how much value an accountant can add.

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 return without professional help, and HMRC's online system is built for exactly that. For a landlord with one property, simple expenses, and no mortgage, doing it yourself is entirely manageable.

The calculation changes as complexity arrives. A second property raises the question of how to apportion shared costs. A mortgage triggers Section 24, which behaves differently from the old interest deduction and produces counterintuitive results as taxable income approaches a higher-rate threshold. A jointly held property means two returns. Selling means capital gains tax and a strict reporting deadline. An HMO brings licensing, utilities, and a more involved expense structure. Each layer is manageable alone, but several at once turn tax administration into a meaningful time cost, and the price of a mistake compounds.

In our work with self-managing landlords across the UK, the pattern is consistent. The people who appoint an accountant early tend to treat the fee as cheap insurance, while those who wait until an HMRC enquiry or an unplanned property sale usually pay more and get less for it. The UK property tax landscape has grown steadily more intricate since 2015, and a good accountant manages two risks at once: paying more tax than you owe, and falling foul of an obligation you did not know applied to you.

What a landlord accountant actually does

A landlord accountant does far more than file a return once a year. The visible job is completing the SA105 property pages of your Self Assessment, applying the right reliefs, and filing before the 31 January deadline. The value sits in everything around it.

Year-round record-keeping support matters more now that Making Tax Digital for Income Tax has begun. A specialist will either maintain your digital records or help you choose and configure compliant software and brief you on what each quarterly update must contain. Tax planning, as distinct from tax compliance, is where a specialist earns the most: reviewing your whole income position rather than your rental income in isolation, and combining legitimate strategies such as timing capital expenditure, pension contributions, splitting ownership between spouses to use both basic-rate bands, or correctly identifying every one of the allowable expenses for landlords you can claim.

Capital gains tax is a specialist function in its own right. When you sell a residential property you have 60 days from completion to report and pay any capital gains tax due, and as at June 2026 the higher rate on residential property is 24 per cent. An accountant consulted after completion can file the return; one consulted before can influence the structure and timing of the disposal, which is where the saving lives. For landlords weighing a restructure, a property accountant should model both personal and limited company ownership on your actual figures rather than a generic comparison.

Section 24 and why specialist advice pays off

Section 24 removed the right of individual landlords to deduct mortgage interest from rental income, replacing it with a 20 per cent tax credit. Since the restriction was fully phased in by April 2020, individual landlords are taxed on rental profit before finance costs, as set out in HMRC's guidance on the change. For a basic-rate taxpayer the effect is broadly neutral. For a higher or additional-rate taxpayer it can be substantial.

Specialist advice matters because Section 24 distorts the headline income figure in ways that reach beyond the tax rate itself. Because interest is no longer deducted before tax is calculated, your reported income looks higher than your economic profit, which can push you into a higher band, taper your personal allowance, and trigger the High Income Child Benefit Charge, none of which is obvious from your rental income alone. A property accountant models all of those interactions on your real numbers.

Section 24 applies only to individual landlords, which is why incorporation has become central to the conversation for higher-rate payers. A limited company still deducts mortgage interest in full against profits, but the analysis is rarely simple. Transferring property into a company usually triggers Stamp Duty Land Tax and potentially capital gains tax unless specific reliefs apply, company buy-to-let mortgage rates are generally higher, and extracting profit adds a further layer of tax. Our guide to whether a limited company is right for UK landlords walks through the trade-offs, but the reliable answer for your situation comes only from a detailed model. For the underlying mechanics, our guide to how rental income is taxed in the UK and the dedicated Section 24 explainer are a useful foundation before any accountant conversation.

Making Tax Digital and your records

Making Tax Digital for Income Tax is now the single biggest reason many landlords appoint an accountant. From 6 April 2026, landlords whose combined income from property and self-employment exceeds £50,000 must keep digital records and submit quarterly updates to HMRC using compatible software. The threshold falls to £30,000 from April 2027 and £20,000 from April 2028, according to HMRC's guidance on who needs to use Making Tax Digital for Income Tax. Our Making Tax Digital guide for landlords sets out exactly what each quarterly update involves.

A good accountant either runs this for you or helps you select compliant software and confirms a clean data handoff, so your quarterly figures are not rebuilt from scratch four times a year. Among the landlords we support through their first Making Tax Digital year, the ones who arrive with categorised digital records spend a fraction of the time, and the fee, of those handing over a year of bank statements and a carrier bag of receipts. Setting the workflow up correctly at the start is far less painful than retrofitting it after several quarters have already been filed.

What to look for in a landlord accountant

The first question is whether the accountant specialises in property or works across many sectors. Property tax is complex enough that a generalist may handle your compliance correctly while missing the planning opportunities, since the real expertise in Section 24, residential CGT, incorporation relief, and the interaction between rental income and the tapered personal allowance is concentrated in firms that work predominantly with landlords.

Ask whether they use and understand your record-keeping software. If you already manage your records, open banking, and quarterly submissions in one place, an accountant familiar with that system can pull your figures directly rather than asking you to translate between tools. Ask whether fees are fixed or hourly, since most reputable landlord accountants now quote a fixed annual fee, which makes budgeting predictable and removes any reason to hold back a question. Ask what their process is for capital gains events, because the 60-day clock is easily missed if a sale completes while the firm is buried in January filings, and a clear intake process for disposals is worth more than one that treats a sale as part of the annual cycle.

Finally, check regulatory status. UK accountants are not required to belong to a professional body, but one regulated by the ICAEW, ACCA, or, for tax-specific work, the Chartered Institute of Taxation, gives you a level of accountability and a complaints route that an unregulated bookkeeper does not. For an accountant whose core role is your landlord accounting and tax, that regulation is a baseline, not a bonus.

What a landlord accountant costs

Fees scale with complexity. A Self Assessment covering a single buy-to-let property typically runs from around £300 to £800 a year. Landlords with several properties, more involved affairs, or a limited company structure should expect £1,000 to £3,000 or more, depending on scope. The figure that matters is whether the fee is proportionate to the value delivered, not whether it is low in absolute terms, and for most landlords with a mortgage or more than one property the cost is recovered through correctly claimed expenses, avoided penalties, and planning a generalist would not spot. Accountancy fees relating to your rental business are themselves an allowable expense against rental income.

When to bring an accountant in

The honest answer is earlier than most landlords do. Many handle their own tax for a year or two and seek help only when something goes wrong, when a second property raises the complexity, or when an HMRC enquiry lands, each of which is a more expensive entry point than appointing someone at the outset.

The clearest moments to bring in specialist input are when your rental income is approaching a band boundary, before you sell a property, before you buy another, and at the point Making Tax Digital obligations begin. If you are a new landlord registering with HMRC for the first time, our guide to registering with HMRC as a landlord covers UTR numbers, Self Assessment registration, and what to do if you have been receiving rent without yet notifying HMRC. To estimate your position before that first conversation, our rental income tax calculator applies Section 24 correctly and shows your indicative tax and MTD start point.

How August works alongside your accountant

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

Open banking, regulated by the FCA and powered by Plaid, connects to your bank account and matches incoming rent to the correct tenancy automatically, with a complete per-property history. Expenses are captured as they occur and categorised against HMRC-recognised types, including the correct treatment of mortgage interest under Section 24. The result is that when your accountant needs your quarterly or year-end figures, they are already clean and categorised in the expenses feature rather than reconstructed at the deadline. August produces year-end financial summaries your accountant can work straight from, so the handoff is a review rather than a rebuild.

Frequently asked questions

How much does an accountant cost for a landlord?

For a single buy-to-let property, a Self Assessment service usually costs around £300 to £800 a year. Landlords with multiple properties, a limited company, or more complex affairs typically pay £1,000 to £3,000 or more. Most specialist landlord accountants now charge a fixed annual fee rather than billing by the hour, and the fee itself is an allowable expense against your rental income.

Is an accountant worth it for a rental property?

For a single, mortgage-free property with simple expenses, many landlords manage well on their own. The value rises sharply once a mortgage brings Section 24 into play, once you hold more than one property, or once a sale, an incorporation decision, or Making Tax Digital enters the picture. In those situations a specialist usually saves more in correctly claimed expenses, avoided penalties, and planning than they charge in fees.

Can I do my own landlord tax return?

Yes. You can register for Self Assessment and file the SA105 property pages yourself, and HMRC's system is designed for it. From April 2026, if your combined property and self-employment income is over £50,000 you must keep digital records and file quarterly updates through compatible software, which is manageable independently but is where many landlords decide professional help is worth the cost.

What is the difference between a bookkeeper and a landlord accountant?

A bookkeeper records and organises your income and expenses through the year. An accountant uses those records to prepare and file your return, apply the correct reliefs, and advise on tax planning such as Section 24, capital gains timing, and incorporation. A specialist property accountant combines both with sector expertise, which is what makes the difference on a complex or growing portfolio.
