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.
£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%.
Enter the purchase price of the property.
Select your buyer type: standard home mover, additional property, first-time buyer, or company.
Read the SDLT due, the surcharge portion, and the effective overall rate.

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