Why Harrow Landlords Need a Specialist Property Tax Accountant
Harrow has one of the largest buy-to-let markets in outer London, with landlords drawn by the Metropolitan, Jubilee and Piccadilly lines and steady rental demand. From Victorian conversions near Harrow-on-the-Hill station to newer flats in Stanmore and Wealdstone, every rental property brings its own income tax, capital gains tax and stamp duty questions. As landlord accountants in Harrow, we handle that work for property investors with one flat or a full portfolio.
Section 24 changed the numbers for every landlord with a mortgage. Mortgage interest now earns a 20% tax credit instead of a full deduction, and from April 2027 property income moves to its own rates of 22%, 42% and 47%. Many Harrow landlords who borrowed heavily now pay higher-rate income tax on profit they never see as cash, which is why tax planning, spouse income splits and limited company structures matter more each year.
Making Tax Digital for Income Tax began on 6 April 2026 for landlords with more than £50,000 of gross rent and self-employment income, and the threshold falls to £30,000 in April 2027. Landlords in scope keep digital records and send quarterly updates to HMRC, so bookkeeping can no longer wait until January. We set up cloud bookkeeping for each property, file the quarterly updates and final declaration, and prepare Self Assessment tax returns for landlords who are not yet caught.
For landlords who hold property through a limited company, we prepare the year-end accounts, file them at Companies House and complete the corporation tax return. When you sell, capital gains tax has to be reported and paid within 60 days of completion. Good accountants for landlords cover all of it, from the first tenancy to the final sale, and our property accountants work on nothing else.



Accounts, tax returns and tax planning for every Harrow landlord
HMO Accountants
Our HMO accountants in Harrow prepare the accounts and tax returns for landlords who let houses in multiple occupation. A shared house brings accounting work a single let does not: licensing fees, room-by-room rent with bills included, fire-safety works that split between repairs and capital, capital allowances on the common parts, and a bigger Section 24 bill because HMO borrowing is usually higher. We are specialist property accountants and treat HMO accounts as routine work.
→SPV Property Company Accountants
Our SPV accountants in Harrow look after landlords who hold buy-to-let or HMO property through a limited company. A property SPV (special purpose vehicle) is a company set up only to hold property, and since Section 24 it is the usual structure for higher-rate property investors building a portfolio. The work is broader than a personal tax return: annual accounts, the corporation tax return, director's loans, dividend planning and Companies House filings. At portfolio scale the after-tax yield is usually better.
→Buy-to-Let Accountants
Our buy-to-let accountants in Harrow prepare Self Assessment tax returns and accounts for landlords with one rental property or a portfolio. Buy-to-let tax goes wrong in three places: the Section 24 mortgage interest calculation, the split between repairs and capital improvements, and how income is shared between joint owners. As landlord accountants we handle this work daily, alongside capital gains tax on a sale and the new Making Tax Digital rules.
→Non-Resident Landlord Tax
Non-resident landlord tax applies to overseas landlords who live abroad and let property in the UK. Under the Non-Resident Landlord Scheme, your letting agent, or your tenants if they pay you more than £100 a week directly, must deduct basic-rate tax from the rent unless HMRC has approved you to receive it gross. We handle the scheme approval, the UK Self Assessment tax return each year, capital gains tax when you sell, and the double taxation position in the country where you live.
→Landlord Self Assessment
We prepare landlord Self Assessment tax returns in Harrow for people with rental income, from a single let to a portfolio. A landlord tax return is more than one figure on the SA105 property pages: it means claiming every allowable expense, applying Section 24 correctly, separating repairs from capital improvements, and reporting capital gains tax on a sale within 60 days. We file returns for landlords every week and make sure the figures stand up if HMRC asks.
