Frequently Asked Questions
How much is stamp duty on a £300,000 house?
For a standard purchase at £300,000 from April 2025: £0 on the first £125,000, 2% on £125,001-£250,000 (£2,500), and 5% on £250,001-£300,000 (£2,500) = £5,000 total. First-time buyers pay £0 (nil rate up to £300,000).
Do first-time buyers pay stamp duty?
First-time buyers pay no stamp duty on the first £300,000 of a property purchase (from 1 April 2025). They pay 5% on the portion from £300,001 to £500,000. If the property costs more than £500,000, the relief does not apply.
What is the additional property surcharge?
If you already own a property and are buying an additional one (buy-to-let, second home), you pay a 5% surcharge on top of standard SDLT rates. This was increased from 3% to 5% on 31 October 2024.
Does stamp duty apply in Scotland and Wales?
No. SDLT only applies in England and Northern Ireland. Scotland has Land and Buildings Transaction Tax (LBTT) and Wales has Land Transaction Tax (LTT) — both have different rates and thresholds.
When do I pay stamp duty?
SDLT must be paid within 14 days of completion. Your solicitor or conveyancer usually handles the payment and filing on your behalf as part of the conveyancing process.
