England and Northern Ireland — rates from 1 April 2025
SDLT is a tax you pay when you buy residential property in England or Northern Ireland above a certain value. It is paid to HMRC and must be settled within 14 days of completion — your conveyancer will usually handle this.
SDLT works on a tiered (or “slice”) system, similar to income tax. You pay the rate shown only on the portion of the price that falls within each band, not on the full purchase price.

| Up to £125,000 | 0% |
| £125,001 – £250,000 | 2% |
| £250,001 – £925,000 | 5% |
| £925,001 – £1,500,000 | 10% |
