Understanding the 5% Surcharge
What is it?
Since April 2025, if you buy an additional property (second home, holiday home, or buy-to-let), you pay an extra 5% on top of the standard stamp duty rates. This applies to the entire purchase price.
When does it apply?
The surcharge applies when you already own another residential property anywhere in the world at the end of the day of purchase, and the new property costs £40,000 or more.
How Much Extra Will You Pay?
| Property Price | Standard SDLT | 5% Surcharge | Total to Pay |
|---|---|---|---|
| £200,000 | £1,500 | +£10,000 | £11,500 |
| £300,000 | £5,000 | +£15,000 | £20,000 |
| £500,000 | £15,000 | +£25,000 | £40,000 |
| £750,000 | £27,500 | +£37,500 | £65,000 |
Can You Get a Refund?
Yes, you may be entitled to a refund if:
- 1.You sell your previous main residence within 36 months of buying the new property
- 2.The new property becomes (or was intended to become) your main residence
How to claim: You must claim the refund within 12 months of selling your previous home (or within 12 months of the filing date for the original return, if later).
