VAT and LTT at a glance
VAT usually forms part of the amount used to work out Land Transaction Tax in Wales when it is chargeable on the transaction.

Does VAT count when working out Land Transaction Tax?
Usually, yes. When a seller or landlord charges VAT on your Welsh property deal, it normally increases the amount used to work out Land Transaction Tax (LTT). Land Transaction Tax replaced stamp duty land tax in Wales in 2018. This point can matter most for business property and leases.
What this rule is about
You calculate LTT by reference to what you give for land or a lease. That can include more than the price shown in the contract. VAT is one possible extra amount.
The key question is simple: was VAT chargeable on the transaction at the tax date? In most cases, the tax date is completion. If the answer is yes, VAT normally goes into the LTT calculation.
That does not mean every property deal has VAT. Many do not. Whether VAT applies is a separate VAT question, but the answer can change the LTT figure.
What the official source says
The legislation includes VAT chargeable on a transaction in the amount used for LTT. There is one important exception for an option to tax land made after the tax date.
- Include VAT if it was chargeable on the land deal.
- Do not include VAT that arises only because an option to tax was made after the tax date.
- After granting a lease, a landlord may opt to tax, and VAT may then be charged on rent even though that option came later.
- That later possibility is not an uncertain future event for LTT.
- If a transfer of a going concern meets all the VAT conditions, no VAT is payable.
- Where no VAT is payable on that basis, use the VAT-exclusive amount for LTT.
- If the transaction does not meet those VAT conditions and the seller charges VAT, include that VAT.
The WRA guidance also says that the VAT rate in force at the tax date is normally the rate used for the LTT calculation. A later rise or fall in the VAT rate does not, by itself, change that original calculation.
Future VAT rate changes do not count. LTT does not treat them as uncertain payments. You do not adjust an earlier LTT calculation simply because VAT may change later.
What this means in practice
Start with the actual VAT treatment of the deal, not with a guess based on the type of property. Commercial sales and leases can have VAT issues that do not arise on an ordinary home purchase.
If the seller charged VAT when the deal completed, include it in the LTT figures. If it was not charged because the transaction qualified as a transfer of a going concern, use the amount before VAT.
- Keep the VAT invoice with the LTT working papers.
- Check whether a seller or landlord has opted to tax the land.
- Check the date of any option to tax, not only whether one exists.
- For a business transfer, check whether the VAT conditions for a transfer of a going concern were met.
- Use the VAT rate that applied at the tax date unless the lease rules below apply.
- Record any later HMRC decision about the VAT treatment.
A later decision can still matter. Where HMRC later decides VAT was due, the WRA guidance tells you to correct the LTT position and include it, even if the deal originally completed without VAT. You must correct it.
It also says the reverse applies. If VAT was included but HMRC later decides that it was not chargeable, there may be less LTT to pay.
How to analyse it
Work through the facts in order. Do not begin with the VAT rate. First work out whether VAT was actually chargeable, and why.
- Identify the land sale, lease, or transfer being taxed.
- Find the tax date, which will usually be completion.
- Check the contract, invoice, and VAT treatment at that date.
- Ask whether VAT was chargeable on the transaction.
- If it was, add the VAT to the amount used for LTT.
- If an option to tax is relevant, check whether it was made after the tax date.
- If it was made after that date, separate VAT caused by that later option from the LTT calculation.
- For a transfer of a going concern, establish whether all relevant VAT conditions were met.
- For a lease, check whether rent is fixed, variable, or uncertain.
Leases need extra care. Where a lease starts on or after a VAT rate change, the WRA guidance gives a split calculation for the net present value of rent. Net present value is a way of putting future rent into one LTT figure.
In that case, use the old VAT rate from the tax date until the day before the first rent payment date. Use the new VAT rate for rent due on or after that first payment date.
Where a lease began before a VAT rate change, a possible later rate change does not by itself alter the original LTT calculation. The position can differ where rent is variable or uncertain and a reconsideration date is reached.
Example
Illustration: A business buys a property for £100,000 and VAT of £20,000 is chargeable on completion. The amount used for the LTT calculation is £120,000, not £100,000.
Now change one fact. The transfer meets all the VAT conditions for a transfer of a going concern, so VAT is not payable. The amount used for LTT is then £100,000.
One further change gives a different result. VAT was not included at first, but HMRC later decides it was chargeable. The WRA guidance says the LTT position must then be corrected to include the £20,000 VAT amount.
Why this can be difficult in practice
You might think the figure in the sale contract settles the point. It does not. A contract may state a price excluding VAT, include VAT in a total, or permit VAT to be added later if the VAT treatment requires it. Timing matters too.
A later option to tax has a specific exception. A later VAT decision, however, may show that the original LTT figure was wrong.
- A price described as “plus VAT” needs checking against the VAT position at the tax date.
- An option to tax made after the tax date has a different LTT result from one made before it.
- A transfer of a going concern is not VAT-free merely because the parties call it one.
- Variable lease rent can trigger a reconsideration calculation using actual VAT rates up to that date.
- For later years of a lease, VAT changes can affect the highest rent in a 12-month period used in the calculation.
- Once a return can no longer be amended, the WRA guidance sets out different routes, depending on whether the amount is an underpayment or an overpayment.
After an HMRC VAT ruling, amend an underpaid LTT return. If the amendment period has ended, write to WRA and state the extra amount now subject to LTT.
For an overpayment, the guidance says to amend the return where possible. If that is no longer possible, it says you may make a repayment claim to WRA under section 63 of the Tax Collection and Management (Wales) Act 2016.
Key takeaways
- VAT charged on a Welsh land deal normally increases the amount used for LTT.
- VAT caused by an option to tax made after the tax date is excluded.
- A later VAT rate change normally does not reopen the original LTT calculation.
- Lease calculations can require special treatment where rent is variable or uncertain.
- Keep VAT evidence, as a later HMRC ruling can require the LTT result to change.
