The surcharge in one sentence
If you complete on a residential property worth £40,000 or more, and at the end of that day you own two or more residential properties anywhere in the world, every nation of the UK will charge you an additional layer of tax on top of the standard rates.
Current surcharge rates

Replacing your main residence?
The surcharge does not apply if you are replacing your main residence and you have sold your previous home on or before completion day. If your sale is delayed you must pay the surcharge up front, then claim it back once your previous home sells — provided the sale happens within 36 months of the new purchase.

Ways to avoid or minimise the surcharge
The PDF goes into detail on five legitimate routes. Here is a summary of each.
Sell before you complete
The simplest approach: exchange and complete on your sale before or on the same day as your purchase. This avoids the surcharge entirely without relying on a refund.
Pay up front and claim a refund
If your sale is delayed, pay the surcharge at completion and claim it back within 36 months once your previous main home sells. You have 12 months from the sale to lodge the claim.
Single dwelling with granny annexe
A property with a self-contained annexe may be treated as a single dwelling, provided the annexe is worth less than one-third of the total property value. This avoids Multiple Dwellings Relief complications.
Mixed-use classification
If the property has a genuine non-residential element (for example, a shop below a flat), it may fall under non-residential rates, which carry no surcharge. HMRC is strict: an office at home or a paddock is usually not enough.
Stay under £40,000
Purchases below £40,000 do not attract any surcharge. Rarely applicable for mainstream homes, but relevant for small plots or lock-up garages.
Worked examples
England: £300,000 buy-to-let while owning main home
Standard SDLT: 0% £125k + 2% £125k + 5% £50k = £5,000. Surcharge: 5% × £300,000 = £15,000. Total: £20,000.
Scotland: £275,000 second home
LBTT: 0% £145k + 2% £105k + 5% £25k = £3,350. ADS: 8% × £275,000 = £22,000. Total: £25,350.
