Property accountants for London landlords

Property accountants in London: what we do

In short: we prepare rental accounts and Self Assessment returns for London landlords, set up Making Tax Digital, work out Capital Gains Tax when you sell, and advise on whether holding property personally or through a limited company suits you best.

Landlord tax rules London landlords ask us about

• Mortgage interest (Section 24): individual landlords cannot deduct mortgage interest from rent. Instead you get a tax credit at 20%. Higher-rate landlords often pay more tax than they expect.
• Joint ownership: rental profit is normally split 50:50 between spouses or civil partners unless you make a Form 17 declaration and own the property in unequal shares.
• Allowable expenses: letting agent fees, repairs, insurance, ground rent, service charges, accountancy fees and replacing furniture in furnished lets.
• Making Tax Digital: from 6 April 2026 landlords with qualifying income over £50,000 must keep digital records and send quarterly updates. The threshold falls to £30,000 from April 2027 and £20,000 from April 2028.
• Selling a property: UK residents must report and pay any Capital Gains Tax on a residential property sale within 60 days of completion.

Personal ownership or a limited company?

A limited company can deduct mortgage interest in full and pays Corporation Tax rather than Income Tax, but moving existing properties into a company can trigger Stamp Duty Land Tax and Capital Gains Tax. We model both options with your figures. See buy-to-let limited company accountants.

Behind on your rental income?

If you have not declared rent in past years, the Let Property Campaign lets you put it right with lower penalties. See our Let Property Campaign help and the HMRC disclosure calculator.
