Frequently Asked Questions

When do I need to pay Stamp Duty?

Stamp Duty must be paid within 14 days of completing your property purchase. Your solicitor usually handles this payment as part of the conveyancing process.

How is Stamp Duty calculated on a second home?

Second homes incur an additional surcharge (currently 3%, increasing to 5% from October 31, 2024) on top of the standard SDLT rates. This applies to the entire property price if it's £40,000 or more.

What qualifies as a first-time buyer?

A first-time buyer is someone who has never owned a property anywhere in the world. Both buyers must be first-time buyers to qualify for the relief on joint purchases.

Can I add Stamp Duty to my mortgage?

While it's possible to add Stamp Duty to your mortgage, this means you'll pay interest on it over the term of your mortgage. It's generally better to pay it as a one-off cost if you can afford to.
