help How Stamp Duty Works
SDLT is a progressive tax on properties in England and Northern Ireland. You only pay each rate on the portion within that band.
For example, a £300k purchase: 0% on the first £250k, then 5% on the remaining £50k = £2,500.
- • First-time buyers: 0% up to £425k, 5% on £425k–£625k. No relief above £625k.
- • Standard: 0% up to £250k, then 5%, 10%, 12%.
- • Surcharge: +3% on every band for additional properties.
