How much is Stamp Duty on a £300,000 house in the UK?
In England or Northern Ireland, SDLT on a £300,000 main home (not first-time buyer) is £5,000. First-time buyers pay £0 thanks to the relief (0% up to £300,000). In Scotland LBTT is £4,600; in Wales LTT is £4,500.
Full answer
For a £300,000 main residence purchase in 2025/26: England/NI SDLT — £0 on the first £125,000, then 2% on £125,001–£250,000 = £2,500, then 5% on £250,001–£300,000 = £2,500. Total £5,000. First-time buyer SDLT relief: 0% up to £300,000, so a first-time buyer pays £0. Buy-to-let/second home adds 5% surcharge: £20,000 total. Scotland LBTT — 0% on first £145,000, 2% on £145,001–£250,000 = £2,100, 5% on £250,001–£300,000 = £2,500, total £4,600 (£3,725 for first-time buyer thanks to £175,000 0% threshold). Wales LTT — 0% on first £225,000, 6% on £225,001–£300,000 = £4,500. Wales has no first-time buyer relief.
