Quick Answer
UK stamp duty is a tiered tax on property purchases. In England and Northern Ireland HMRC charges SDLT with 0% up to £125,000, 2% to £250,000, 5% to £925,000, 10% to £1.5m and 12% above. First-time buyers get a £300,000 nil-rate band. Scotland uses LBTT and Wales uses LTT at their own tiered rates.

How UK Stamp Duty (SDLT) Works
Stamp Duty Land Tax (SDLT) is a tax paid by the buyer when purchasing property or land in England and Northern Ireland. It is one of the largest upfront costs in a property transaction, often running into thousands of pounds, yet many buyers do not fully account for it when budgeting. SDLT is a progressive tax, which means it works similarly to income tax bands: you only pay each rate on the portion of the purchase price that falls within that band, not on the entire amount.
For example, if you buy a property for £400,000 at standard rates, you pay 0% on the first £250,000 (so nothing) and 5% on the remaining £150,000, which equals £7,500. You do not pay 5% on the full £400,000. This marginal system means the effective tax rate is always lower than the top band rate that applies to your purchase.
SDLT must be paid within 14 days of the completion date, which is when the property legally changes hands and keys are exchanged. Your solicitor or conveyancer handles the SDLT return and payment as part of the conveyancing process. They submit the return to HMRC electronically and pay the duty from the completion funds. Late filing attracts automatic penalties starting at £100 and interest charges on any unpaid amount.
Scotland and Wales have their own property transaction taxes with different names, rates, and thresholds. Scotland uses Land and Buildings Transaction Tax (LBTT), administered by Revenue Scotland, while Wales uses Land Transaction Tax (LTT), administered by the Welsh Revenue Authority. Although all three systems are progressive, the band structures differ significantly, which is why this calculator lets you select the correct country for an accurate result.
2025/26 SDLT Rates
The tables below show the current stamp duty rates for residential property purchases in England and Northern Ireland for the 2025/26 tax year. Rates differ depending on whether you are a standard buyer, a first-time buyer, or purchasing an additional property.

First-Time Buyers vs Second Home Buyers
The difference in stamp duty between a first-time buyer and someone purchasing an additional property is substantial. The table below compares SDLT at several common price points to illustrate the potential savings from first-time buyer relief and the additional cost of the second home surcharge.
| Property Price | First-Time Buyer SDLT | Standard Buyer SDLT | Additional Property SDLT |
|---|---|---|---|
| £250,000 | £0 | £0 | £7,500 |
| £350,000 | £0 | £5,000 | £15,500 |
| £425,000 | £0 | £8,750 | £21,500 |
| £500,000 | £3,750 | £12,500 | £27,500 |
| £625,000 | £10,000 | £18,750 | £37,500 |
| £750,000 | N/A (standard rates) | £25,000 | £47,500 |
Practical Stamp Duty Examples
Example 1: First-Time Buyer Purchasing a £250,000 Flat
Sarah is a first-time buyer purchasing a one-bedroom flat in Manchester for £250,000. Because the property price is below the first-time buyer nil-rate threshold of £425,000, she pays no SDLT at all. If Sarah were a standard buyer (having previously owned property), she would still pay £0 because £250,000 also falls within the standard nil-rate band. However, if this were her second property, she would pay the 3% additional property surcharge on the full amount: 3% of £250,000 = £7,500. First-time buyer status saves Sarah nothing in this case because the standard nil-rate band already covers the purchase price, but the additional property surcharge would have added a significant cost.
Example 2: Second Property at £500,000
James already owns his main residence and is buying a buy-to-let investment property in Bristol for £500,000. Because this is an additional property, the 3% surcharge applies on top of standard rates. The calculation is: 3% on the first £250,000 = £7,500, plus 8% on the next £250,000 (from £250,001 to £500,000) = £20,000. James's total SDLT bill is £27,500, which represents an effective rate of 5.5%. Compare this to a standard buyer at the same price who would pay just £12,500 (0% on the first £250,000 plus 5% on the next £250,000). The additional property surcharge adds £15,000 to the cost, which James needs to factor into his rental yield calculations.

Example 3: Family Home at £750,000
The Patel family is buying a four-bedroom house in Surrey for £750,000 as their main residence, having sold their previous home. As standard buyers, their SDLT is calculated as: 0% on the first £250,000 = £0, plus 5% on the next £675,000 (from £250,001 to £750,000, noting this stays within the second band up to £925,000) = £25,000. Their total SDLT is £25,000, an effective rate of 3.33%. Note that first-time buyer relief would not apply at this price since the property exceeds the £625,000 ceiling. If the Patels had not yet sold their previous home at completion, they would be treated as additional property buyers and pay £47,500 instead. They could reclaim the £22,500 surcharge if they sell the old home within three years.
Tips to Reduce Your Stamp Duty Bill
Claim first-time buyer relief. If you have never owned property anywhere in the world and the purchase price is £625,000 or less, you automatically qualify for the enhanced nil-rate band. Both buyers in a joint purchase must be first-time buyers. This relief can save up to £6,250 compared to standard rates.
Time your sale correctly. If you are replacing your main residence, try to sell your existing property before or on the same day as the new purchase to avoid the 3% additional property surcharge. If timing makes this impossible, you can pay the surcharge upfront and reclaim it within three years of the new purchase, provided you sell the old property within that window.
Consider transfer between spouses. Transfers of property between married couples or civil partners are exempt from SDLT, provided the transfer is not part of a separation arrangement. This can be useful for tax planning when restructuring property ownership within a household.
Negotiate the price strategically. Because SDLT bands have specific thresholds, a small reduction in price can sometimes produce outsized savings. For example, negotiating a price of £250,000 instead of £260,000 saves £500 in SDLT at standard rates (5% on the £10,000 difference), on top of the £10,000 itself. At the additional property rate, that same £10,000 reduction saves £800 in SDLT.
Explore Multiple Dwellings Relief. If you are buying two or more dwellings in a single transaction (for example, a house with an annexed flat), Multiple Dwellings Relief allows the SDLT to be calculated based on the average price per dwelling rather than the total price. This can result in significant savings on larger purchases. Use our inheritance tax calculator to understand the long-term tax implications of property ownership.
