Tout savoir sur Stamp Duty (SDLT) Calculator
📋Présentation+
SDLT is charged on a sliding scale of the purchase price, with each band taxed only on the portion of the price that falls within it. Buying an additional residential property (buy-to-let, second home) adds a 5% surcharge on top of standard rates across every band. First-time buyers get relief on properties up to £625,000, with 0% up to £425,000. Companies buying residential property face the same additional-property rates as individuals, plus a flat 17% charge on purchases over £500,000 unless a relief applies.
💡 Bonnes pratiques
- The 5% surcharge applies to the whole price across every band, not just the amount above a threshold — it's a much bigger jump than it first looks.
- Selling your main home within 36 months of buying a new one can qualify you for a refund of the surcharge paid.
- Company purchases of high-value residential property (over £500,000) can face a flat 17% rate — check reliefs for genuine property rental/development businesses before assuming the worst case.
🔢 Exemple concret
£300,000 purchase as an additional property: standard bands plus the 5% surcharge on the whole price give an SDLT bill of £14,000, an effective rate of about 4.7%.

FAQ — Stamp Duty (SDLT) Calculator

No — Scotland has Land and Buildings Transaction Tax (LBTT) and Wales has Land Transaction Tax (LTT), both with different bands and rates from SDLT.
Can I get first-time-buyer relief and the surcharge exemption together?+
First-time buyers by definition aren't buying an additional property, so the two categories are mutually exclusive — select whichever applies to your purchase.
