Stamp Duty Calculator
Calculate Stamp Duty Land Tax (SDLT) on your property purchase for 2026/27.
Enter the full property purchase price and select the buyer type. First-time buyers benefit from SDLT relief on properties up to £500,000 in England and Northern Ireland. Additional property buyers pay a 3% surcharge on the entire purchase price from pound one — this applies to landlords and those purchasing a second home while retaining their main residence. For Scotland, select LBTT; for Wales, LTT. All three use tiered bands but with different thresholds and rates. The result shows SDLT broken down by band. Your solicitor handles the return and payment within 14 days of completion — budget for this as a separate cost not typically included in the mortgage.
