Work out how much stamp duty you’d need to pay

How Stamp Duty Works

Standard threshold: SDLT is due on residential properties priced over £125,000 in England and Northern Ireland.

First-time buyers: If you’re buying your first home for less than £500,000, you may qualify for reduced or zero Stamp Duty.

Additional properties: Buying a second home or a buy-to-let? Expect a 3% surcharge on top of the standard rates, applied to each band of the purchase price.

Scotland and Wales: Different rules apply—Scotland uses Land and Buildings Transaction Tax (LBTT) and Wales uses Land Transaction Tax (LTT).

Why It Matters

Stamp Duty must be reported to HMRC and paid within 14 days of completion. Missing this deadline can lead to penalties, so it’s important to know your liability.

Progressive Tax System

Since 2014, SDLT has worked like income tax—each portion of your property price is taxed at the relevant rate, rather than one flat rate across the whole price. This usually means lower costs compared to the old system.
