How much stamp duty do I pay on a second property in 2026?
For additional properties (buy-to-let, second homes) in 2026, you pay the standard SDLT rates plus a 5% surcharge on the entire purchase price. This surcharge was increased from 3% to 5% in October 2024. For example, on a £250,000 property, the total stamp duty including the surcharge would be approximately £15,000.

Is stamp duty different in England, Wales and Scotland?
Yes. England and Northern Ireland use Stamp Duty Land Tax (SDLT). Wales uses Land Transaction Tax (LTT) with different thresholds—the nil-rate band is £225,000 vs England's £125,000. Scotland uses Land and Buildings Transaction Tax (LBTT) with its own rates and thresholds. Each system has different rates, so your stamp duty varies depending on where you buy.
When do I need to pay stamp duty?
You must pay stamp duty within 14 days of completing your property purchase. Your solicitor handles the payment during the conveyancing process, but the money comes from your funds. This is not a cost you pay months later—you need to budget for it upfront as part of your completion costs.
