Everything you need to know about UK stamp duty (SDLT): rates, bands, first-time buyer relief, and how to calculate what you'll pay.
Understanding Stamp Duty Land Tax
Stamp Duty Land Tax (SDLT) is a tax levied on property purchases in England and Northern Ireland. Scotland has its own version called Land and Buildings Transaction Tax (LBTT), while Wales uses Land Transaction Tax (LTT). Despite the different names, all three operate on similar progressive band principles.
SDLT is one of the largest upfront costs when buying property, often amounting to thousands of pounds. Understanding how it works helps buyers budget accurately and potentially reduce their tax liability through available reliefs.
How SDLT Works
Like income tax, SDLT uses progressive bands — you only pay the rate for each portion of the price that falls within that band. For example, on a £400,000 property, you pay 0% on the first £250,000 and 5% on the remaining £150,000, for a total of £7,500.
This progressive structure means the effective (average) rate is always lower than the highest marginal rate that applies. A common misconception is that the highest rate applies to the entire purchase price.
Current SDLT Rates (England & Northern Ireland)
Standard residential rates: 0% up to £250,000, 5% on £250,001-£925,000, 10% on £925,001-£1,500,000, and 12% on amounts above £1,500,000.
First-time buyer rates: 0% up to £425,000, 5% on £425,001-£625,000. Properties over £625,000 don't qualify for first-time buyer relief.
Additional property surcharge: An extra 3% applies to each band when buying a second home, buy-to-let, or additional residential property.
First-Time Buyer Relief
First-time buyers benefit from significant SDLT savings. On a £400,000 property, a first-time buyer pays £0 in SDLT, while a standard buyer pays £7,500. To qualify, neither purchaser must have previously owned a property anywhere in the world, and the property must be residential and purchased as a main residence.
Scotland: LBTT
Scotland's Land and Buildings Transaction Tax uses different thresholds: 0% up to £145,000, 2% on £145,001-£250,000, 5% on £250,001-£325,000, 10% on £325,001-£750,000, and 12% above £750,000. An Additional Dwelling Supplement of 6% applies to second homes.
Wales: LTT
Wales's Land Transaction Tax: 0% up to £225,000, 6% on £225,001-£400,000, 7.5% on £400,001-£750,000, 10% on £750,001-£1,500,000, and 12% above £1,500,000. Wales also has a higher rate for additional properties.
How to Reduce Stamp Duty
Legal strategies include: claiming first-time buyer relief, purchasing below band thresholds, negotiating fixtures and fittings separately (these aren't subject to SDLT), using shared ownership schemes, and timing purchases around policy changes.
FAQ
When do I pay stamp duty?
Within 14 days of completion. Your solicitor or conveyancer typically handles the SDLT return and payment on your behalf.
Is stamp duty tax deductible?
For buy-to-let properties, stamp duty can be claimed as a capital expense when calculating Capital Gains Tax upon sale. It's not deductible against rental income.
