Property & landlords accountancy in Northern Ireland
Owning property in NI has changed beyond recognition since 2017. Section 24 mortgage interest restriction reshaped the maths for higher-rate landlords. Furnished Holiday Let status changed in April 2025. Making Tax Digital for Income Tax lands in 2026 and 2027 with quarterly filings. We help individual and portfolio landlords across NI navigate the decisions that actually move the tax bill.
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 big decision for most NI landlords is whether to incorporate. Inside a limited company, mortgage interest is back to fully deductible and corporation tax is 19 to 25%. But you pay it again on the way out as dividends. The maths is personal. We model it case by case before any incorporation, factoring SDLT exposure, mortgage refinancing, and CGT on transferred properties.
We work with single-property BTL landlords, HMO investors, holiday-let owners (Causeway Coast, Mournes, North Coast), and portfolio landlords with twenty or more properties. The setup is the same: clean property-by-property P&L, capital allowances on furnishings, and an annual tax review that catches the optimisation opportunities before year end, not after.

How we help property & landlords businesses
Frequently asked about property & landlords accountancy
Should I move my BTL portfolio into a limited company?
Sometimes yes, sometimes no. The maths depends on your other income, the size of the portfolio, mortgage terms, and your exit horizon. We run the comparison properly, including the costs of getting there (SDLT, refinancing, CGT). For most higher-rate landlords with three or more mortgaged properties and a long horizon, the answer leans yes. For accidental landlords or those near retirement, often no.
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 setup, software, and quarterly submissions as part of the service.
I run an Airbnb 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 reliefs, and the pension-contribution-eligible income status. We model your specific position and the steps that recover the most of what FHL gave 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 SDLT, CGT, and income tax consequences. We walk you through the trade-offs before you decide.
