Higher LTT rates on a second home in Wales
Buying a home in Wales while still owning another home may mean paying higher Land Transaction Tax. This is Wales’s equivalent of extra stamp duty on a second home. As the difference can be large, check your position before completion.
What this rule is about
Land Transaction Tax, or LTT, applies when you buy land or property in Wales. Higher residential rates may apply when you buy a home while already owning another home.
Completion is usually the key time. Tax professionals call this the effective date. Normally, it is the completion date rather than the day you first agree the deal.
You may think that owning two homes at any stage is enough. The position is not quite that simple. The answer can depend on what you own at the end of completion day and on whether you are replacing your main home.
What the official source says
The Welsh Government page says that higher residential rates may apply when you buy a residential property and already own one or more residential properties. It also says that the higher rates may not apply if you are replacing your main residence.
- For transactions with an effective date on or after 11 December 2024, you pay 5% on the first £180,000.
- You pay 8.5% on the slice from £180,001 to £250,000.
- You pay 10% on the slice from £250,001 to £400,000.
- You pay 12.5% on the slice from £400,001 to £750,000.
- You pay 15% on the slice from £750,001 to £1.5 million.
- You pay 17% on any slice above £1.5 million.
- The page says these rates do not apply where contracts were exchanged before 11 December 2024.
What this means in practice
These rates work in bands. You do not apply the highest rate you reach to the full price. Instead, calculate each slice of the price and add the results.
For an individual, the law considers whether you own another qualifying home at the end of the effective date. A share in a home can count, as can a home outside Wales.
- Check every home or share in a home that you own on completion day.
- Check property held by a spouse or civil partner if you live together.
- Do not assume a buy-to-let, holiday home, or inherited share is irrelevant.
- Consider whether the new home is replacing the home you normally live in.
- Keep the exchanged contract, as its date may matter for the 11 December 2024 rate change.
How to analyse it
Begin with the property and the date. Then consider ownership and the main-home position. Following this order helps you avoid a common mistake: calculating tax before deciding which set of rates applies.
- Is the property residential property for LTT?
- What is the effective date, which is normally completion?
- Was the contract exchanged before 11 December 2024?
- Are you an individual, a company, or acting through a trust?
- At the end of that day, do you own another qualifying home or share?
- Are you replacing the home you normally live in?
- Once the correct rates are known, calculate tax in price bands.
Example
Priya buys a Welsh holiday flat for £300,000. She still owns the house where she lives. Assuming the higher rates apply and the transaction has an effective date on or after 11 December 2024, she calculates: £180,000 at 5% equals £9,000; £70,000 at 8.5% equals £5,950; and £50,000 at 10% equals £5,000. Her total is £19,950.
Now change one fact. If Priya buys a new main home and meets the rules for replacing her old main home, the higher rates may not apply. Moving, rather than buying a holiday flat, is not enough by itself.
Why this can be difficult in practice
The question is often not “do I own a second home?” Instead, it is “what interests count at completion, and am I genuinely replacing my main home?” Documents, dates and the way someone actually used a property can determine those answers.
Companies face different treatment from people. The statute generally includes a company that buys a home worth £40,000 or more within the higher-rates rules, although limited exceptions exist.
Trusts also need care. For some trusts, the law treats a beneficiary rather than the trustee as the buyer or owner. Other cases have different rules.
- Moving house does not automatically remove the higher rates.
- A jointly owned share can matter, even where you do not own the whole property.
- Living separately from a spouse or civil partner can change the result.
- The name on the title is not always the whole answer for a trust.
- A rate table is only useful after you have identified the right tax treatment.
Key takeaways
- Higher LTT rates may apply if you own another home at completion.
- From 11 December 2024, the higher-rate bands start at 5% on the first £180,000.
- Replacing your main home may change the result, but the facts and dates matter.

- Information about a spouse or civil partner living with you
- Evidence that a sold property was your main home, where relevant
- Trust documents where a trust is buying or owns property
