Landlord accountants for UK rental income

A landlord accountant prepares your rental accounts and tax return, applies the mortgage interest restriction correctly, and files quarterly Making Tax Digital updates where they apply. If you own through a company, that includes the company accounts and Corporation Tax return. The part that saves money is the advice: who should own what, when to sell, and whether a cost is a repair you can claim now. We do both, for one flat or a portfolio.

Not always. Plenty of landlords with one property, one mortgage and tidy records file their own return. The case for paying someone grows when the interest restriction tips you into a higher band, when you and a partner own on an unequal split, when you sell at a gain, or when Making Tax Digital brings you into quarterly updates. We will tell you on the first call whether you need us.

The fee follows the work: the number of properties, whether they sit in your name, jointly or in a company, and how complete the records are. One flat on a personal return is a small job; a portfolio with a company and quarterly filing is a bigger one. We quote after the first call, and you approve the fee before work starts.

A landlord tax accountant works on rental property every day; a general practice sees it a few times a year among many other kinds of work. The rules have changed almost every year since the interest restriction was announced: the stamp duty surcharge, the 60-day capital gains report, the end of the furnished holiday lettings tax regime, and now quarterly reporting. A generalist can be competent and still miss one, and the cost sits with you.

Yes. HMRC's Let Property Campaign lets you tell HMRC about undeclared rent yourself, and the penalties are much lower than if HMRC finds it first. We establish the years involved, compute what is owed with interest and the penalty, and submit the disclosure for you. The earlier you come forward, the better your position, so it is worth a call before HMRC writes to you.

Four things decide it: your tax band, the size of your mortgage interest, whether you live off the profit, and how long you will keep it all. A company deducts interest in full, but profit you take out is taxed again. Moving property you already own is treated as a sale, so capital gains tax and stamp duty both apply, and incorporation relief, which can defer the gain, must now be claimed for transfers from 6 April 2026. We model both routes on your own figures before you decide.

Yes, if your rental and self-employed income together is over £50,000 before expenses: quarterly updates have applied since 6 April 2026. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028. Joint owners count only their share, and property held in a limited company is outside the regime. Our MTD checker tells you which year applies to you.

Not really. The one awkward stretch is the run-up to the January deadline, when a handover and a return compete for the same weeks. At any other point it is straightforward: we ask your current accountant for clearance, take over the records and the last filed return, and get authorised with HMRC as your agent. Switching carries no HMRC penalty and starts nothing again.

Yes. The core of agency work is keeping client money separate from the agency's own. We reconcile the client account, recognise commission and management fees when they are earned, deal with VAT on fees, and handle the non-resident landlord scheme where you collect rent for owners abroad. Payroll, the agency's annual accounts and its Corporation Tax return are part of the same job.

Bring the rent statements or the agent's annual summary, the lender's interest statement, receipts for work on each property with repairs and improvements in separate piles, completion statements for anything bought or sold, and any HMRC letters. If you own through a company, add the last filed accounts. If quarterly reporting applies to you, bank feeds into accounting software will save you time all year.

Most buy-to-let investors need three things from a specialist: a tax return that handles the rental income and the interest restriction correctly, quarterly Making Tax Digital updates once the threshold applies, and company accounts if any property sits in a limited company. Beyond that compliance, use an accountant who advises before you buy, refinance or sell, because that is when the tax is decided. We will tell you on the first call which of these you need.

You can claim the running costs of letting: agent and management fees, insurance, repairs and maintenance, ground rent and service charges, accountancy fees, and replacing furnishings in a furnished let. Mortgage interest is different: individuals get a tax credit of 20% of the interest instead of a deduction, rising to 22% from April 2027, while companies deduct it in full. Improvements cannot be set against rent, but they reduce the gain when you sell.
