SDLT rates shown are for England and Northern Ireland residential purchases from April 2025 onwards. Scotland uses Land and Buildings Transaction Tax (LBTT); Wales uses Land Transaction Tax (LTT) - both have different rates. First-time buyer relief applies only on properties up to £500,000. Additional dwelling surcharge (5% since October 2024) applies to buy-to-let, second homes, and company purchases. Always verify current rates with HMRC or a solicitor before completing.
