Stamp Duty is one of the bigger costs to plan for when you buy a home, but in Northern Ireland the news is mostly good: prices here are the most affordable in the UK, so the large majority of first-time buyers pay nothing at all. This guide sets out exactly what you would pay in 2026, with worked examples for typical Northern Ireland purchases.
What is Stamp Duty?
Stamp Duty Land Tax (SDLT) is a tax paid to HMRC when you buy a property over a certain price. It applies in England and Northern Ireland; Scotland and Wales run their own equivalents. It is charged on a tiered basis, so you pay a different rate on each portion of the price rather than one flat rate on the whole thing.
Your solicitor normally files the return and pays it on your behalf as part of completion. The figures below are the rates in force in 2026; SDLT thresholds are set by the UK government and do change, so always confirm the current position when you buy.
Standard rates (your only home)
If this will be the only residential property you own, you pay:
- 0% on the price up to £125,000
- 2% on the portion from £125,001 to £250,000
- 5% on the portion from £250,001 to £925,000
- 10% on the portion from £925,001 to £1.5 million
- 12% on anything above £1.5 million
Because the tax is tiered, a £250,000 home costs a home mover £2,500 (nothing on the first £125,000, then 2% on the next £125,000), not £5,000.
First-time buyer relief
First-time buyers get a more generous deal:
- 0% on the price up to £300,000
- 5% on the portion from £300,001 to £500,000
If the property costs more than £500,000 the relief disappears and the standard rates above apply to the whole price. To qualify, everyone buying must be a first-time buyer and you must intend to live in the property as your main home.
Given that the Northern Ireland average house price sits well below £300,000, the practical effect is that most local first-time buyers pay no Stamp Duty whatsoever. See our first-time buyer guide for Northern Ireland for how this fits with deposits and borrowing.
What that means in Northern Ireland: worked examples
- £160,000 home, first-time buyer: £0.
- £160,000 home, home mover: £700 (2% on the £35,000 above £125,000).
- £200,000 home, first-time buyer: £0.
- £200,000 home, home mover: £1,500.
- £300,000 home, first-time buyer: £0.
- £300,000 home, home mover: £5,000.
The additional property surcharge
If buying the property means you will own more than one (a buy-to-let or a second home), you pay a 5% surcharge on top of the standard rates, and it applies to the whole price, including the portion that would otherwise be taxed at 0%. In practice the bands become 5%, 7%, 10%, 15% and 17%.
So a £160,000 buy-to-let attracts £8,700 in Stamp Duty (5% on the first £125,000, then 7% on the next £35,000). The surcharge also applies if you are buying before selling your current main residence, though you can usually reclaim it if you sell the old home within the allowed window.
When do you pay?
The return and payment are due within 14 days of completion. Your solicitor handles this as part of the conveyancing, but the money has to come from you, and it cannot normally be added to the mortgage, so budget for it alongside your deposit and legal fees.
