Choosing an Accountant as a Landlord

Not every accountant who can file a Self Assessment return is well placed to advise a landlord. Rental property has its own rules, from Section 24 finance cost restrictions to the capital-versus-revenue test on repairs, and a generalist accountant who mostly works with small trading businesses can miss details that a landlord specialist would catch as a matter of routine. Choosing well the first time saves years of paying for advice that does not quite fit your situation.

This guide covers what to look for in a landlord accountant, the questions worth asking before you sign up, how fees are typically structured, and the signs that it is time to move on from one you already have.

Why a generalist accountant may not be enough

Property tax has enough quirks that experience with landlords specifically matters more than general accountancy competence alone. An accountant who mostly deals with limited company trading businesses may be entirely competent at bookkeeping and corporation tax, but less familiar with the detail of Section 24, the replacement of domestic items relief, or how furnished holiday let rules differ from standard letting, simply because they see these questions rarely.

This does not mean you need the most expensive specialist firm in the country. It means asking, early on, how much of the accountant's client base is landlords, and how comfortable they are with the specific structure you have or are considering, whether that is a single property in your own name, a portfolio split across personal and limited company ownership, or a mix that includes an HMO or a furnished holiday let. Our Section 24 guide and tax on rental income guide are useful background reading before that conversation, so you can judge how confidently an accountant answers rather than taking a generic answer at face value.

What to look for

A handful of things tend to separate a good landlord accountant from an adequate one:

• A recognised qualification. Look for ACA, ACCA, AAT or CIOT membership, which confirms a baseline of training and professional standards, and means there is a professional body to complain to if something goes seriously wrong.
• Landlord or property-sector clients as a meaningful part of their book. Ask directly how many landlord clients they have and roughly how large those portfolios tend to be, since advice that works for someone with one flat does not always translate cleanly to someone with fifteen properties.
• Comfort with your ownership structure. If part or all of your portfolio sits in a limited company, or you are weighing up incorporating, make sure the accountant regularly handles company accounts and corporation tax, not just personal Self Assessment.
• A clear position on software and digital records. With Making Tax Digital for Income Tax now live for higher-income landlords and rolling out further over the next two years, an accountant who has not adapted their own processes is a warning sign. Our Making Tax Digital guide covers what compliant record keeping actually involves.
• Responsiveness outside the January rush. Ask how quickly they typically respond to a query in, say, June, not just whether they can file your return on time. An accountant who is unreachable for eleven months of the year and frantic in the twelfth is a difficult one to get proactive advice from.

Questions to ask before signing up

A short conversation before you commit tells you far more than a website ever will:

• What proportion of your clients are landlords, and what is the typical portfolio size you work with?
• How do you want records delivered, and do you have a preferred software or software integration?
• What is included in your standard fee, and what counts as extra work billed separately?
• How do you handle a change during the year, such as buying a new property, changing ownership structure or moving into Making Tax Digital?
• Can you give an example, without naming a client, of a mistake you have caught in a landlord's records that would have cost them money if it had gone unnoticed?

That last question is particularly telling. An accountant who works with landlords regularly will usually have a ready answer, whether that is a repair wrongly claimed as revenue when it should have been capital, a missed opportunity to split ownership more tax-efficiently between spouses, or a finance cost calculation that had not accounted for Section 24 correctly. A vague or generic answer suggests less day-to-day landlord experience than the marketing implies.

Fee structures explained

Landlord accountancy fees are usually charged in one of a few ways, and it is worth understanding which model you are agreeing to before you sign anything:

• A fixed annual fee, covering Self Assessment preparation and filing for an agreed number of properties, with extras such as a new property, an HMRC enquiry or advisory work on incorporation billed separately. This is the most predictable option and the easiest to budget against.
• An hourly rate, more common for advisory work or for a portfolio that changes shape often, which can be cost-effective if your affairs are straightforward but expensive and unpredictable if they are not.
• A tiered package, where the fee scales with the number of properties or the complexity of your structure, for example a step up in price once you move from personal ownership to a mix of personal and limited company holdings.

Whichever model applies, ask what happens if Making Tax Digital quarterly updates are added on top of the annual filing, since some firms include this in their existing fee and others treat it as a new, separate service. Getting this in writing before the first quarter arrives avoids an awkward conversation about an invoice you were not expecting.

When to switch accountants

A few signs suggest it may be time to look elsewhere, even if the relationship has not been actively bad:

• You are always the one chasing. If getting a response to a simple question routinely takes weeks, that gap tends to widen, not narrow, as your portfolio grows.
• You have outgrown their expertise. An accountant who was a perfectly good fit for one property may not be the right one once you are weighing up incorporation, an HMO conversion or a limited company restructure.
• Advice feels generic rather than specific to you. If every recommendation could apply to any small business rather than reflecting your actual portfolio, structure and plans, you are likely paying for compliance rather than genuine advice.
• Fees rise without a clear reason. A rising fee for a portfolio that has not grown is worth questioning directly, and comparing against what a landlord specialist elsewhere would charge for the same work.

Switching accountants mid-relationship is more straightforward than most landlords expect. Your new accountant handles the professional handover directly with your previous one, and having clean, property-by-property records ready to hand over, rather than a shoebox to sort through, makes the transition considerably smoother. Our working with an accountant guide covers what to prepare for a new accountant, whichever one you choose.
