UK Stamp Duty 2026 — Complete Buyer's Guide

Stamp Duty Land Tax (SDLT) is one of the largest upfront costs in buying property in England and Northern Ireland. On a £400,000 home purchase in 2026, your stamp duty bill could be anywhere from £5,000 (first-time buyer) to £32,000 (additional dwelling surcharge). Understanding exactly how much you owe — and which reliefs you qualify for — is essential before you make an offer, arrange your deposit, or plan your moving budget. This guide covers current 2026 SDLT rates, first-time buyer relief, the second home surcharge, and how to calculate your exact bill with worked examples.

How SDLT Works — Tiered Calculation

SDLT is calculated on a tiered or "slice" basis, exactly like income tax. You pay the applicable rate only on the portion of the purchase price that falls within each band — not on the entire price. This is a common source of confusion: a buyer at £251,000 does not pay 5% on the full price, only on the £1,000 that falls into the 5% band. The lower bands still apply to the lower portions of the price. Understanding this slicing principle is essential for calculating your correct SDLT liability.

Standard SDLT Rates 2026 (England & Northern Ireland)

Following the expiry of the temporary threshold increases in April 2025, the standard SDLT rates for residential property in England and Northern Ireland are: £0 to £125,000 — 0%; £125,001 to £250,000 — 2%; £250,001 to £925,000 — 5%; £925,001 to £1,500,000 — 10%; over £1,500,000 — 12%. Worked example for a £350,000 purchase: first £125,000 at 0% = £0; next £125,000 (£125k–£250k) at 2% = £2,500; remaining £100,000 (£250k–£350k) at 5% = £5,000; total SDLT = £7,500.

First-Time Buyer Relief 2026

First-time buyers purchasing in England and Northern Ireland qualify for SDLT relief if neither buyer has ever owned a residential property before — anywhere in the world. Current relief (from April 2025): on purchases up to £300,000, the rate is 0% (no SDLT payable at all). On purchases between £300,001 and £500,000, 0% applies on the first £300,000 and 5% on the remainder. On purchases above £500,000, no first-time buyer relief applies and standard rates are charged from £0. Worked example — first-time buyer at £425,000: £0–£300,000 at 0% = £0; £300,001–£425,000 at 5% = £6,250; total SDLT = £6,250 (versus £11,250 at standard rates — a saving of £5,000).

Second Home and Buy-to-Let Surcharge 2026

Anyone purchasing an additional residential property — a second home, holiday let, or buy-to-let investment — pays a 5% surcharge on top of the standard SDLT rates across every band (increased from 3% to 5% in October 2024). The surcharge applies if you will own two or more residential properties after completion, even if the new purchase is lower in value than your existing home. Worked example — second home at £300,000: £0–£125k at 5% (0%+5%) = £6,250; £125k–£250k at 7% (2%+5%) = £8,750; £250k–£300k at 10% (5%+5%) = £5,000; total SDLT = £20,000 (versus £5,000 at standard rates). This surcharge makes buy-to-let significantly less attractive than it was pre-2025.

Scotland and Wales

SDLT only applies to purchases in England and Northern Ireland. Scotland uses Land and Buildings Transaction Tax (LBTT) with its own rate bands and thresholds, administered by Revenue Scotland. Wales uses Land Transaction Tax (LTT) with its own bands, administered by the Welsh Revenue Authority. Both operate on the same tiered slice principle as SDLT but with different threshold amounts. If you are buying in Scotland or Wales, use the specific LBTT or LTT calculator for your country — applying SDLT rates to Scottish or Welsh purchases will give the wrong answer.

When is Stamp Duty Due?

SDLT must be paid and the return filed with HMRC within 14 days of completion (the date you receive the keys). Your solicitor or conveyancer normally handles the payment on your behalf from the funds you provide at completion. If you are a cash buyer without a solicitor, you can file and pay via the HMRC SDLT portal directly. Failure to pay within 14 days results in an automatic £100 late filing penalty plus interest on the unpaid amount — rising to £200 if more than 3 months late.

Other SDLT Reliefs Worth Knowing

• •Multiple Dwellings Relief (MDR): when purchasing two or more dwellings in a single transaction (e.g., a block of flats), SDLT is calculated on the average price per dwelling rather than the total — significantly reducing the bill. Subject to a minimum of 1% of total consideration.
• •Charities relief: registered charities purchasing property for charitable purposes pay 0% SDLT.
• •Company purchases: when a company (not an individual) purchases a residential property above £500,000, a flat 15% SDLT rate applies — significantly higher than individual rates. Seek specialist tax advice before purchasing residential property through a company.
• •Non-UK residents surcharge: overseas buyers purchasing residential property in England and Northern Ireland pay an additional 2% surcharge on top of all other applicable rates.
