SDLT Guide: Stamp Duty Land Tax UK 2026/27 — Rates, Bands, Reliefs and Five Worked Examples
Buy a £450,000 home in England in May 2026 and HMRC takes £12,500 in Stamp Duty Land Tax before you have unpacked a single box. Buy the same property as a buy-to-let and the bill is £35,000. Buy it as a non-UK-resident and add another £9,000 on top. The slice between those numbers is the entire architecture of SDLT, and the lesson from a year of post-reversion data is simple: SDLT now bites three completing buyers in five, and the cliff edges are sharper than they were under the temporary 2022 thresholds. The nil-rate band is back at £125,000. The first-time buyer threshold sits at £300,000 — and dies completely above £500,000, the only major UK tax that wipes out relief at a hard cap rather than tapering it. The additional-property surcharge has been at 5% since 31 October 2024 (up from 3%). Multiple dwellings relief was abolished on 1 June 2024 and there is no plan to reinstate it. The 2% non-UK-resident surcharge added on 1 April 2021 is still live and stacks on top of the additional-property surcharge for non-resident landlords. This guide is the 2026/27 working reference: the current bands and rates from HMRC, five fully worked examples covering the typical UK buyer profiles, a UK-wide comparison with Scotland's LBTT and Wales's LTT at four price points, and a step-by-step method to calculate your own bill before you sign anything. Run your target purchase price through the free SDLT calculator at any point — the result is your single most important number, because it is the only completion-day cost that has zero negotiating room with your lender or solicitor.
