When the Higher Rates of Land Transaction Tax Apply in Wales

Land Transaction Tax (LTT) is the Welsh tax on buying property and land, and it replaced Stamp Duty Land Tax in Wales on 1 April 2018. The Welsh Government sets its rates and bands¹. If you already own a home and buy another one in Wales, you normally pay the higher rates of LTT rather than the main residential rates. Those higher rates start at 5% on the first £180,000 of the price and rise to 17% above £1.5 million².

The higher rates are not a separate tax. They are a second set of bands applied to the same transaction, and the difference between the two sets is what you pay. If you are replacing your main home, you can pay the higher rates at the time and then claim a refund once the old home sells, provided you sell within three years³.

This page covers who pays the higher rates, what each band costs, how the refund works, and the deadline for filing and paying.

Who pays the higher rates of Land Transaction Tax

The higher rates apply to residential purchases where the buyer already has an interest in another dwelling, and to purchases by companies and other non-natural persons. The buyer is the person liable to pay the tax due on a chargeable transaction⁶. In practice, the solicitor or conveyancer handling the purchase files the return and pays the tax on the buyer's behalf, but the liability sits with the buyer.

The rates changed for all bands from 11 December 2024⁷. That means a purchase completed on or after that date is charged under the new bands, even if the price was agreed earlier. There is a transitional rule: where contracts were entered into, or the substantial performance of a contract took place, before 11 December 2024, the previous rates continue to apply, unless one of the exclusions applies⁸. The exclusions cover cases where the contract is varied, where an option or right of pre-emption is exercised, or where there is an assignment, subsale or similar transaction on or after 11 December 2024 that entitles someone other than the original purchaser to call for a transfer⁸.

For first-time buyers, the position is different from England. First-time buyer relief applies for the predecessor tax, but not to Land Transaction Tax⁹. There is no reduced LTT rate for first-time buyers in Wales. Guidance for buyers states that first-time buyers buying buy-to-let properties will pay the standard home-buyer rates of LTT, skipping the usual buy-to-let surcharge⁵. That is a specific carve-out for first-time buyers, and it sits alongside the general rule that additional properties attract the higher rates.

Welsh landlords pay an extra 3% Land Transaction Tax on top of standard rates, according to guidance for buyers¹⁰. That figure describes the surcharge element in general terms; the banded rates set out below are the ones that apply to the transaction.

Higher rates by band: from 5% on the first £180,000 to 17% above £1.5 million

The higher rates are banded, so each slice of the price is taxed at its own rate rather than the whole price being taxed at the top rate. The bands below apply to higher rates residential property transactions in Wales from 11 December 2024⁸.

The first band and the fifth band are confirmed in the amending regulations: 5% on the first tax band, not more than £180,000, and 15% on the fifth tax band, more than £750,000 but not more than £1.5 million⁸. The third band is 10% on the portion above £250,000 but not more than £400,000⁸. Independent guidance published on 14 May 2026 sets out the same structure, with 5% on £0 to £180,000, 8.5% on £180,001 to £250,000, 15% on £750,001 to £1.5 million and 17% on £1.5 million and above².

The higher residential rates in Wales run in bands: 5% on the first £180,000, 8.5% on £180,001 to £250,000, 15% on £750,001 to £1.5 million and 17% above £1.5 million⁷. The Welsh Revenue Authority's published rates are the ones to check for a transaction, and the amending regulations set the first band at 5% for higher rates transactions¹⁰. In England and Northern Ireland, the higher rates for additional dwellings are 5% on the first £125,000, 7% on £125,001 to £250,000, 10% on £250,001 to £925,000 and 15% on £925,001 to £1.5 million⁶.

Properties below £40,000 are charged at 0%². That is separate from the notification threshold: taxpayers must notify the Welsh Revenue Authority of all land transactions with a value above £40,000⁴.

Higher rates compared with main residence rates

The main residential rates and the higher rates use the same band structure but different percentages. The higher rates are the ones that apply when you already own property, and the difference between the two sets is the cost of buying an additional home rather than replacing your main one.

The refund mechanism is what links the two. When a refund for a higher rates residential transaction is claimed, the original transaction is amended to a main rate residential transaction¹¹. In other words, the transaction is reassessed as if the main rates had applied from the start, and the difference is returned. That is why the refund is not a discretionary payment: it corrects the rate that should have applied once the old home has sold.

For comparison, the equivalent tax in Scotland, Land and Buildings Transaction Tax, has different rates and bands for different types of property, with separate rates for residential properties and residential property with the Additional Dwelling Supplement¹². The top Scottish rate is 12% on the portion of the price above £750,000¹³. In England and Northern Ireland, Stamp Duty Land Tax higher rates for additional dwellings run at 5% on the first £125,000, 7% on the portion above £125,000 up to £250,000, 10% above £250,000 up to £925,000, 15% above £925,000 up to £1.5 million, and 17% on the remainder¹⁴. The Welsh and English higher rate structures are similar in shape but use different band boundaries and different starting points.

Replacing your main home: up to three years to sell and claim a refund

If you buy a new main home before your old one sells, you pay the higher rates at completion and then claim the difference back. The taxpayer has up to three years to sell their previous main residence and claim a refund³. The same three-year window is set out in the higher rate refunds statistics¹⁵ and in the dataset covering higher rate refunds⁴.

The equivalent rule in England and Northern Ireland is expressed in the same terms: if you sell or give away your previous main home in the three years after you buy your new home, you can apply for a refund of the higher rate part of your Stamp Duty Land Tax bill¹⁶. The permitted period for disposing of the sold dwelling is the period of three years beginning with the day after the effective date of the transaction concerned¹⁴.

The refund is not automatic. It has to be claimed, and the claim depends on the sale of the previous home completing within the window. If the sale falls through or takes longer than three years, the higher rates stand. That is the main risk in this area, and it is worth building the timing into the plan for the move rather than treating the refund as certain.

There is also a specific refund rule for private landlords who buy a dwelling and then lease it to a local authority in Wales through Leasing Scheme Wales. Under that rule, the higher residential rates of LTT are refunded, and the main residential rates of LTT continue to apply¹⁷. That is a targeted relief rather than a general one, and it applies only where the letting is through the scheme.

Filing and paying: 30 days from completion

When filing an LTT return, the organisation paying the return has 30 days after the effective date to submit and pay the tax⁷. The same 30-day deadline is set out in the higher rate refunds dataset⁴. The effective date is normally the date of completion.

The 30-day deadline is a hard one. Late filing and late payment attract penalties and interest, and the fact that a refund may later be due does not change the deadline for the original return. The return has to be filed and the higher rate tax paid first; the refund is a separate process that follows the sale of the previous home.

The notifiable threshold is £40,000. Taxpayers must notify the Welsh Revenue Authority of all land transactions with a value above £40,000⁴. For comparison, the equivalent Stamp Duty Land Tax rule requires a return where the price or value of the property or land is £40,000 or more, and no return is needed where the price or value was £39,999 or less¹⁸. The Welsh threshold is expressed as above £40,000, so a transaction at exactly £40,000 sits at the boundary and the Welsh Revenue Authority's guidance should be checked for the specific case.

For leases, the notification position depends on the term and the consideration. Under the equivalent Scottish rules, the grant of a lease for a period of seven years or more where any chargeable consideration other than rent is less than £40,000 falls below the notification threshold⁶. The same £40,000 figure is the notifiable threshold for land transactions in Wales⁴.

The higher rate refunds dataset covers April 2018 to March 2027, and the next update is expected on 29 October 2026⁴. Land Transaction Tax statistics are regularly revised, and the values for the latest period are provisional¹⁵.

Where the higher rates do not apply

The higher rates do not apply to every purchase by someone who owns property. The rules turn on what is being bought, what the buyer already owns, and whether the transaction falls within one of the reliefs. First-time buyers buying a buy-to-let property pay the standard home-buyer rates of LTT, skipping the usual buy-to-let surcharge⁵. Private landlords leasing a dwelling to a local authority in Wales through Leasing Scheme Wales can claim a refund of the higher residential rates, with the main residential rates continuing to apply¹⁷.

There is no additional surcharge for non-UK residents buying in Wales. Guidance for buyers states that if you are buying in Wales there is no additional surcharge, and the same rules apply as for UK residents⁵. That is a genuine difference from England and Northern Ireland, where a separate non-UK resident surcharge operates. In Wales, the question is whether you already own property, not where you are resident.

The higher rates also interact with the main rates through the refund mechanism, which means a buyer who sells a previous main home within three years ends up paying the main rates rather than the higher ones³. The refund is the route by which a replacement purchase is treated as a replacement rather than an addition.

For anyone buying in Wales, the practical points are the same: establish which set of rates applies before completion, budget for the higher rates if there is any doubt, and diarise the 30-day filing deadline and the three-year refund window. The Welsh Revenue Authority publishes the rates and bands, and the refunds statistics show how the system works in practice⁴.
