Answer

Stamp Duty Land Tax (SDLT) is a tax on property purchases in England and Northern Ireland, paid by the buyer, not the seller. Scotland has Land and Buildings Transaction Tax and Wales has Land Transaction Tax — different names, different thresholds, same basic idea.

It is charged in bands, and only on the portion within each band. This is the point people most often get wrong. If a threshold sits at £250,000 and you buy at £260,000, you pay the higher rate only on the £10,000 above it — not on the whole price. There is no cliff edge where crossing a threshold by a pound costs you thousands.

Rates and thresholds change frequently, often at Budgets and sometimes temporarily, so any specific figures date quickly. Check the current rates on the HMRC calculator rather than relying on an article.

What reliably affects what you pay:

First-time buyer relief reduces or removes the charge below a threshold, subject to a price cap and to genuinely never having owned property anywhere in the world.

Additional property surcharge. Buying a second home or a buy-to-let attracts a percentage surcharge on the entire price. It also catches people who have not yet sold their previous main home — though a refund can be claimed if the old home is sold within a set period.

Non-resident surcharge adds a further amount for overseas buyers.

Mixed-use and non-residential property is taxed on a different, generally lower scale, which is occasionally exploited aggressively.

Practical points: SDLT is due within a short window after completion and your solicitor normally files and pays it, but the legal responsibility is yours. Budget for it alongside legal fees, survey and moving costs — it is often the largest single transaction cost.
