How much is Stamp Duty on a £500,000 house in the UK?
England/NI SDLT on a £500,000 main home is £15,000 (£10,000 for a first-time buyer). Scotland LBTT is £23,350. Wales LTT is £24,000.
Full answer
For a £500,000 main residence purchase in 2025/26: England/NI SDLT — £0 on first £125,000, 2% on next £125,000 = £2,500, 5% on next £250,000 = £12,500. Total £15,000. First-time buyer relief: 0% up to £300,000, then 5% on £200,000 = £10,000. Above £500,000, first-time buyer relief disappears entirely (full rates apply from £1). Buy-to-let surcharge adds 5% to each band — total £40,000. Scotland LBTT (no FTB at this level): 0% × £145,000 + 2% × £105,000 + 5% × £75,000 + 10% × £175,000 = £23,350. Wales LTT: 0% × £225,000 + 6% × £175,000 + 7.5% × £100,000 = £18,000... actually for the £400,001–£750,000 band the rate is 7.5%, so calculation: 6% × £175,000 = £10,500, then 7.5% × £100,000 = £7,500, total £18,000.
