Stamp duty on a second home
The short answer
Buying a second home or a buy-to-let means paying more purchase tax than an ordinary buyer, and how much more depends entirely on which nation you are buying in.
England and Northern Ireland add a surcharge to every band. Scotland charges a flat supplement on the whole price. Wales uses a completely separate, higher set of bands.
If you are buying before selling your current home, you will usually pay the higher rate up front and can reclaim it later once the sale completes, within a time limit.
Three taxes, three sets of rules
Property purchase tax is devolved, so which nation you buy in decides not only the rate but the entire structure of the charge. The extra you pay on a second property works differently in each.
| Where | What it is called | How the extra is applied |
|---|---|---|
| England and Northern Ireland | Stamp Duty Land Tax | A surcharge added on top of every standard band, so the whole purchase is taxed at a higher rate than it would otherwise be. |
| Scotland | Land and Buildings Transaction Tax, plus the Additional Dwelling Supplement | A flat percentage of the entire purchase price, added to the normal charge. Not banded at all. |
| Wales | Land Transaction Tax | An entirely separate higher rate schedule, not the main rates plus a surcharge. The bands and percentages differ throughout. |
That structural difference matters. In Scotland the supplement applies to the full price from the first pound, so it kicks in at the same rate whether the property costs £100,000 or £400,000. In Wales the higher schedule starts charging from a much lower threshold than the main rates do, which catches out buyers who assume the nil-rate band still applies.

What counts as an additional property
This is where most of the confusion sits, and the answer is less intuitive than people expect. The higher rate generally applies if, at the end of the day of purchase, you own more than one residential property and are not replacing your only or main residence.
Some situations that catch people out:
- Buying before selling. If your purchase completes before your old home sells, you own two properties that day, so the higher rate applies even though you are genuinely moving house.
- Property owned abroad. Residential property anywhere in the world can count towards the test, not just UK property.
- Inherited shares. A share in a property you inherited may count, depending on the size of the share and how long you have held it.
- Buying with a partner who already owns. The test generally looks at both buyers, so one person's existing property can trigger the higher rate on a joint purchase.
- Helping a child buy. If a parent is named on the mortgage or deeds and already owns a home, the higher rate can apply to what everyone thinks of as the child's first purchase.
You can often get it back
The most useful thing to know: if you paid the higher rate because your purchase completed before your old home sold, you can usually reclaim the extra once the sale goes through, provided it happens within the time limit set by the relevant nation.
This is a refund you have to apply for. Nobody sends it automatically, and the deadlines are real. Your conveyancer should flag it, but not all of them do, so it is worth raising the question yourself if you are in this position. The amount involved is usually thousands of pounds.
The time limits and claim processes differ between England and Northern Ireland, Scotland and Wales, so check the relevant authority's guidance rather than assuming they are the same.
Buy-to-let and the wider picture
If you are buying to let rather than to live in, the purchase tax is only the first of several costs that differ from an ordinary purchase. Mortgage rates on buy-to-let are typically higher, deposits are usually larger, and the tax treatment of rental income has changed considerably in recent years in ways that affect higher-rate taxpayers particularly.
The purchase tax alone can be a substantial share of your upfront costs, so it belongs in your calculation before you commit to a price, not after an offer is accepted.

Before you commit
Purchase tax on an additional property is one of the largest single costs of the transaction and it cannot be added to the mortgage. Work it out before you make an offer, confirm the exact figure with your conveyancer before exchange, and if you are buying before selling, ask them in writing about the refund process at the same time.
