Choosing the right stamp duty calculator

Most buyers in England and Northern Ireland only need the main SDLT calculator. It covers home movers, first-time buyers, additional properties and non-UK residents in one place. Use a dedicated calculator when your situation needs extra explanation:

First purchase: the relief checker confirms whether every buyer qualifies. If one buyer has owned a home anywhere in the world, the relief is lost.
Keeping your current home: the buy-to-let and second home calculators apply the 5% surcharge.
Buying in Scotland or Wales: SDLT does not apply there. Use the LBTT or LTT calculator.
Already paid: the surcharge refund calculator shows what you can reclaim if you sold your previous main home within 3 years.
