Stamp Duty Land Tax rates explained

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.

What about Scotland and Wales?

Scotland has its own property purchase tax called Land and Buildings Transaction Tax (LBTT), administered by Revenue Scotland. Wales uses Land Transaction Tax (LTT), administered by the Welsh Revenue Authority. Both have different thresholds and rates. This calculator covers England and Northern Ireland only.
