How stamp duty works in the UK

Stamp Duty Land Tax (SDLT) is one of the biggest upfront costs when buying property in England and Northern Ireland — but the way it's calculated catches many buyers off guard. Here's a clear explanation of how the bands work, what changes for first-time buyers, and what to budget for beyond the SDLT itself.

SDLT works like income tax — in bands. You only pay the higher rate on the portion of the purchase price that falls within each band, not on the whole amount. This is a common misunderstanding that causes people to overestimate their SDLT bill.

Worked example — £400,000 property, home mover
First £125,000 at 0% (nil-rate band)£0
Next £150,000 (£250,001–£400,000) at 5%£7,500
Total stamp duty£7,500
Effective rate (£7,500 ÷ £400,000)1.875%
Common misconception

Many buyers think crossing into a higher band means the entire purchase price is taxed at the higher rate. It doesn't — only the portion above the threshold is taxed at the higher rate, just like income tax bands.

Effective rate vs headline rate

The effective rate (total SDLT divided by purchase price) is always lower than the highest band rate. On a £500,000 purchase the headline rate is 5%, but the effective rate is 2.5% — because half the purchase price is in the 0% band.

First-time buyers in England and Northern Ireland benefit from a higher nil-rate threshold. Following the April 2025 changes, first-time buyers pay no stamp duty (SDLT) on the first £300,000 of properties priced up to £500,000. Above £500,000, first-time buyer relief does not apply and standard rates are charged.

Saving for a first-time buyer at £300,000
Standard SDLT at £300,000£3,500
First-time buyer SDLT at £300,000£0
Saving£8,750

Qualifying rules: you must never have previously owned a residential property anywhere in the world — not just the UK. This includes inherited properties. If buying jointly, both buyers must be first-time buyers for the relief to apply. If one buyer has previously owned, you lose the relief entirely and pay standard rates.

Above £500,000: first-time buyer relief does not apply at all. The full standard SDLT rates apply from £1, as if you were a home mover. This cliff edge means a £626,000 purchase costs significantly more in SDLT than a £624,000 purchase.

If you own any other residential property at the time of purchase — anywhere in the world — you pay a 5% surcharge on top of all standard SDLT rates. Crucially, the 5% surcharge applies to the entire purchase price including the nil-rate band, making it significantly more expensive than standard rates.

£350,000 additional property vs standard
Standard SDLT£5,000
5% surcharge on £350,000£10,500
Total additional property SDLT£15,500
Extra cost vs standard purchase£10,500 more

Refund available: if you sell your main residence within 3 years of buying the additional property, you can reclaim the 5% surcharge from HMRC. This applies when people buy a new home before selling their old one — they pay the surcharge at completion and reclaim it once the original home is sold.

When do you pay stamp duty?
SDLT must be paid within 14 days of completing your property purchase. Your solicitor handles the SDLT return and payment as part of conveyancing. It is not included in your mortgage — you must fund it separately, typically from savings alongside your deposit.
Does stamp duty apply in Scotland and Wales?
No. SDLT applies in England and Northern Ireland only. Scotland has Land and Buildings Transaction Tax (LBTT) and Wales has Land Transaction Tax (LTT), both with different rates and thresholds. This calculator covers England and Northern Ireland only.
Can stamp duty be added to the mortgage?
Some lenders allow you to add SDLT to your mortgage, but this is generally not advisable — you'll pay interest on it for the full mortgage term. Most financial advisers recommend paying SDLT from savings. If cashflow is tight, speak to a mortgage broker about your specific situation before deciding.
What happens if I buy with a partner who already owns a property?
If either buyer already owns a residential property, you both lose first-time buyer relief and pay standard rates. If the existing property is owned solely by one partner and the new purchase is in both names, the 5% additional property surcharge applies to the entire purchase. Structuring the purchase in the first-time buyer's name alone avoids the surcharge — but has legal and financial implications worth discussing with a solicitor.
Are there any other stamp duty exemptions?
Yes — transfers between spouses on separation or divorce, inherited properties (no SDLT on inheritance itself, though the 5% surcharge may apply if you later buy another property), zero-carbon homes below £500,000 (full relief until March 2027), and purchases by registered charities for charitable purposes. Some commercial property transactions also have different SDLT structures.

UK Stamp Duty 2026 — rates and surcharge explained

What is the stamp duty surcharge for additional properties in 2026?

In 2026, the SDLT additional property surcharge is 5% on top of standard rates, applied across the full purchase price from the first pound. The surcharge was increased from 3% to 5% in October 2024 and remains at 5% in 2026. It applies to second homes, buy-to-let properties, and any residential purchase where you already own another property anywhere in the world. On a £300,000 additional property, the surcharge alone adds £15,000 to your SDLT bill — nearly trebling it compared to a standard purchase.

What are the UK SDLT rates for additional properties in 2026?

For additional residential properties in 2026, SDLT is charged at standard rates plus a 5% surcharge on every band: 5% on £0–£125,000, 7% on £125,001–£125,000, 7% on £125,001–£250,000, 10% on £250,001–£925,000, 15% on £925,001–£1.5m, and 17% above £1.5m. The surcharge applies to the full purchase price from pound one — not just the portion above a threshold. This makes the effective cost significantly higher than standard SDLT.

What are the standard SDLT rates for 2026?

The standard SDLT rates for England and Northern Ireland in 2026 are: 0% on the first £125,000, 2% on £125,001–£250,000, 5% on £250,001–£925,000, 10% on £925,001–£1,500,000, and 12% above £1,500,000. These are progressive — you only pay the higher rate on the portion above each threshold, not on the whole price. First-time buyers pay 0% up to £300,000 (on properties up to £500,000), then 5% on the portion between £300,001 and £500,000. Above £500,000, standard rates apply.

How much stamp duty on a £300,000 house in 2026?

For a standard home mover: 0% on £125,000 (£0), 2% on £125,001–£250,000 (£2,500), 5% on £50,000 (£2,500). Total: £5,000. For a first-time buyer: 0% on everything up to £300,000 = £0. For an additional property: £2,500 standard SDLT plus 5% surcharge on the full £300,000 (£15,000) = £17,500 total. The surcharge dramatically increases the cost for buy-to-let investors and second home buyers.

Do first-time buyers pay stamp duty in 2026?

First-time buyers in England and Northern Ireland pay no stamp duty (SDLT) on properties up to £300,000 in 2026, provided the purchase price is £500,000 or less. On properties between £300,001 and £500,000, they pay 5% on the portion above £300,000. Above £500,000, first-time buyer relief does not apply and standard rates are charged on the full price. To qualify, you must never have previously owned a residential property anywhere in the world.

Can I reclaim the additional property surcharge?

Yes — if you paid the 5% additional property surcharge because you temporarily owned two homes while moving, and you sell your previous main residence within 3 years of the new purchase, you can reclaim the full surcharge from HMRC. This commonly applies to people who buy their next home before selling their current one. The refund must be claimed within 12 months of selling the old property.

Does stamp duty apply in Scotland and Wales?

No. SDLT applies in England and Northern Ireland only. Scotland uses Land and Buildings Transaction Tax (LBTT) with different rates and thresholds. Wales uses Land Transaction Tax (LTT). If you are buying in Scotland or Wales, you will need to use the relevant LBTT or LTT calculator — the rates and relief structures differ significantly from SDLT.

Non-UK resident surcharge — 2% on top

If you are not resident in the UK for at least 183 days in the 12 months before your purchase, a further 2% surcharge applies on top of all other SDLT rates. If the purchase is also an additional dwelling, both the 5% additional property surcharge and the 2% non-resident surcharge apply — potentially 7% on top of standard rates.
