What affects
your SDLT bill

The calculator gives you the headline figure. But your actual position can be more nuanced depending on your specific circumstances.

01
First-time buyer relief
Available on purchases up to £500,000. Zero SDLT on the first £300,000, then 5% on the remainder. Relief is lost entirely if the price exceeds £500,000.
02
Additional dwelling surcharge
A 5% surcharge applies if you already own a property and are purchasing another — including buy-to-let and holiday homes. Increased from 3% in October 2024.
03
Non-UK resident surcharge
An additional 2% applies to buyers who are not UK residents — defined as those present in the UK for fewer than 183 days in the 12 months before purchase.
04
Mixed-use & commercial
Different SDLT rates apply to commercial property, mixed-use buildings, and non-residential land. Speak with Nathan if your purchase is not straightforward residential.
