Property and landlord accountants in Belfast and Northern Ireland
Owning property in Belfast and across Northern Ireland has changed beyond recognition since 2017. Section 24 reshaped the maths for higher-rate landlords. Furnished Holiday Let status went in April 2025. Making Tax Digital for Income Tax lands in 2026 and 2027 with quarterly filings. And the three questions landlords actually ring us about are whether to hold property personally or through a company, what a sale will cost in capital gains tax, and how to get the rental figures right in the first place. We answer all three, for single-property landlords and portfolios alike.
Talk to us about property & landlordsTax for property is a moving target. Section 24 means mortgage interest is no longer a deductible expense, it is a 20% tax credit, which costs higher-rate taxpayers thousands a year. The loss of Furnished Holiday Let status in April 2025 removed the favourable rules many short-let landlords relied on. From April 2026 MTD-ITSA applies to property income over £50,000; April 2027 for over £30,000; April 2028 for over £20,000.
The question we are asked most is whether to hold rental property personally or through a limited company. Held personally, the profit is taxed as part of your income at 20%, 40% or 45%, and Section 24 restricts mortgage interest to a 20% credit. Held in a company, that interest is a fully deductible expense again and profits are taxed at corporation tax rates of 19% to 25%, but you pay tax a second time when you take the money out as dividends or salary. Neither answer is right in the abstract. It turns on your other income, whether the properties are mortgaged, how long you intend to hold them, and whether you need the rent to live on. We model both, on your figures, before anyone forms a company.
Getting property into a company is itself a sale in the eyes of HMRC, which is where the second question starts. Transferring a property you already own into your own company is treated as a disposal at market value, so capital gains tax can arise even though no money changes hands, unless a relief applies, and the company pays stamp duty on the way in. The same rules govern an ordinary sale. Residential gains are taxed at 18% or 24% depending on where the gain sits against your income, after the £3,000 annual exempt amount, and where tax is due on a UK residential disposal the return and the payment fall due within 60 days of completion rather than at the next self-assessment deadline. That 60-day clock catches more landlords out than any other rule in property tax.
We work with single-property landlords, HMO investors in Belfast, holiday-let owners on the Causeway Coast and in the Mournes, and portfolio landlords with twenty or more properties. The setup is the same whatever the size: a clean property-by-property profit and loss, capital allowances where they are genuinely available, and a review before the tax year closes rather than after it, when most of the options have already gone.

How we help property & landlords businesses
Frequently asked about property & landlords accountancy
I have one rental property. Should it be in a limited company?
Usually not, and it costs you nothing to hear that. For a single unmortgaged property, or where the rental profit sits inside your basic-rate band, a company adds filing costs and a second layer of tax for very little gain. The case gets stronger with higher-rate income, mortgage debt caught by Section 24, several properties, and a long horizon. We run the comparison on your figures and tell you which way it falls.
Should I move my existing portfolio into a limited company?
Sometimes yes, sometimes no, and the cost of getting there is the part people forget. Moving property you already own into your own company is a disposal at market value, so capital gains tax can arise even though no money changes hands, unless a relief applies, and the company pays stamp duty on the way in. Mortgages usually have to be refinanced at company rates. For higher-rate landlords with three or more mortgaged properties and a long horizon the answer often leans yes, but only once those costs are on the table.
What capital gains tax will I pay when I sell a rental property?
Residential property gains are taxed at 18% or 24% depending on where the gain sits against your income, after the annual exempt amount of £3,000. The gain is the sale price less what you paid, your buying and selling costs, and any capital improvements. If you lived in the property yourself at some point, private residence relief reduces the gain for that period. We calculate it before you accept an offer, so the tax bill is not a surprise afterwards.
Do I really have to report a property sale within 60 days?
If capital gains tax is due on a UK residential property disposal, yes. The return and the payment are both due within 60 days of completion, separately from your self-assessment return, and late filing brings penalties. It is the single most common thing landlords are caught by. Tell us before you complete, not the following January.
When does MTD for Income Tax affect me as a landlord?
From April 2026 if your gross property income is over £50,000. From April 2027 if it is over £30,000. From April 2028 if it is over £20,000. We handle the setup and the quarterly submissions as part of the service.
I run a holiday let on the Causeway Coast. What changed in April 2025?
Furnished Holiday Let status was abolished. You lose the capital allowances on furnishings, the more generous CGT treatment, and the pension-contribution-eligible income status. We model your specific position and the steps that recover the most of what FHL used to give you.
I inherited a property. What are my tax options?
Probate value sets your CGT base cost, which is usually a meaningful uplift. You can sell, let, or move in. Each has different stamp duty, capital gains and income tax consequences. We walk you through the trade-offs before you decide.
Do you work with landlords outside Belfast?
Yes. We are based in Belfast and act for landlords right across Northern Ireland, including people who own property here and live elsewhere. Most of the work happens by email, phone and video call, with meetings in the office when they help.
