Frequently Asked Questions
Why is stamp duty different for first-time buyers?
First-time buyers pay 0% up to £300,000 and 5% on the portion between £300,000 and £500,000, as long as the total price doesn't exceed £500,000. £300,000 is exactly the relief's 0% ceiling.
What if I'm buying a second home?
You pay an extra 5% surcharge on top of standard rates across the whole price — on £300,000 that adds £15,000 to the standard-rate bill.
Is stamp duty the same across the UK?
No. This is the England/Northern Ireland system (SDLT). Scotland has Land and Buildings Transaction Tax and Wales has Land Transaction Tax, both with different bands.
