Do I need an accountant as a UK landlord?

Written by Iftikhar Rashid FCCA — 16 years in practice, specialist in landlord tax.

Short answer

Not legally — but most landlords with more than one property, a mortgage, or any plans to sell benefit significantly from a specialist. Section 24 costs higher-rate landlords £5,000–£30,000+ per year if unplanned. MTD Income Tax is now live for gross income above £50,000. CGT on a disposal must be reported within 60 days. One well-advised decision typically covers years of accountant fees.

Do you need one? A quick decision guide

Are you a higher-rate or additional-rate taxpayer?

Yes → Section 24 costs you significantly more than a basic-rate taxpayer. A specialist models and plans it.
Watch → Section 24 has less impact — but MTD may still apply.

Do you have a mortgage on your rental property?

Yes → Section 24 restricts your interest relief to 20%. A specialist quantifies the impact and your options.

Is your gross rental income above £50,000?

Yes → MTD Income Tax is live. You need software setup, HMRC registration, and quarterly submissions.
Watch → Below £50k but above £30k — April 2027 scope. Plan now.

Are you planning to sell a property in the next 3 years?

Yes → CGT planning before exchange can save thousands. 60-day reporting after completion is mandatory.

Do you have an SPV or are you considering one?

Yes → SPV accounting (annual accounts + CT600) is a separate compliance obligation requiring a specialist.

Do you have 3 or more properties?

Yes → Complexity compounds — multiple SA105 pages, multiple deadlines, higher volume of expense decisions, potential HMO rules.

FAQs

Do I legally need an accountant as a UK landlord?

No — there is no legal requirement to use an accountant as a UK landlord. You can file your own self-assessment return. HMRC's online service accepts landlord returns directly. However, the complexity of UK property tax — Section 24, MTD Income Tax from April 2026, CGT on disposals, SPV structuring — means most landlords with more than one or two properties benefit significantly from specialist help.

When does an accountant start to pay for itself for a landlord?

For most landlords, an accountant pays for itself through one of four situations: (1) correctly claiming all allowable expenses the landlord would have missed; (2) modelling Section 24 impact and recommending a response — saving £2,000–£30,000+ per year for higher-rate landlords; (3) advising on the timing of a property disposal to minimise CGT; (4) correctly assessing whether an SPV transfer makes financial sense before irreversible SDLT and CGT costs are incurred.

Can I do my own landlord self-assessment?

Yes. HMRC's online service allows landlords to file their own SA100 with SA105 property pages. If your portfolio is simple — one or two properties, straightforward income, no capital transactions, below the MTD threshold, no SPV — self-filing is reasonable. Once you add complexity (Section 24 exposure, multiple properties, SPV, CGT planning, MTD quarterly requirements), the risk of error and missed reliefs typically outweighs the accountant's cost.

What do landlords actually get from a specialist accountant?

More than just filing. A specialist landlord accountant provides: correct SA105 property pages; MTD Income Tax setup and quarterly submissions from April 2026; Section 24 modelling to understand your tax position; SPV vs personal-name analysis; CGT planning before disposals; year-round advisory access; and an Annual Compliance Review that catches changes in your position each year.

Is it worth using an accountant for just one rental property?

It depends on your situation. If you are a basic-rate taxpayer, the property has no mortgage (so Section 24 doesn't bite), and you have no plans to sell, self-filing is reasonable. If you are a higher-rate taxpayer, have a mortgage, are approaching the MTD threshold, or plan to sell — even one property generates enough complexity to justify specialist help.
