Estimate your Stamp Duty Land Tax bill as an American or other non-UK-resident buyer — including the non-resident and additional-property surcharges, broken out separately so you can see exactly what each one costs. Free, instant, no sign-up.
This is an estimate using standard England & Wales residential SDLT bands for guidance only. Scotland (LBTT) and Wales (LTT) use different systems. Rates and thresholds change — always confirm with your solicitor or HMRC before completion. If you go on to meet the UK residence test, or sell another property within 3 years, you may be able to reclaim the relevant surcharge — see our SDLT refund guide for the exact tests and deadlines.
This tool applies the standard England & Wales residential SDLT bands, then adds the relevant surcharges:
| Band | Rate |
|---|---|
| £0 – £125,000 | 0% |
| £125,001 – £250,000 | 2% |
| £250,001 – £925,000 | 5% |
| £925,001 – £1,500,000 | 10% |
| £1,500,001+ | 12% |
On top of the standard band calculation, a 5% surcharge applies to the full purchase price if you already own another residential property, and a further 2% non-resident surcharge applies if you don’t meet the UK residence test. Both can apply simultaneously. Full detail and sources: our methodology page.
Both surcharges are potentially refundable in specific circumstances: the non-resident surcharge if you become UK resident within 12 months of completion, and the additional-property surcharge if you sell your other property within 3 years. Read the full rules in our SDLT refund guide for Americans.
