If you are buying property in Wales, the tax you pay is Land Transaction Tax (LTT), not Stamp Duty Land Tax. The two taxes share the same broad architecture, but LTT is administered by the Welsh Revenue Authority under the Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act 2017, the band thresholds are different, the surcharge structure is different, the relief regime is leaner, and the return clock is more generous. This page walks the 2026/27 main residential rate table and three positive Welsh-specific structural points that buyers asking about "stamp duty in Wales" typically need.
If your purchase is in England or Northern Ireland, go to our SDLT rates and surcharge pillar instead, because the regimes do not overlap. Scotland operates a third devolved regime (Land and Buildings Transaction Tax administered by Revenue Scotland) with its own rate table and the Additional Dwelling Supplement at 8%. The cross-jurisdictional comparison table further down lays out the four-nation picture in one place.
Three things Welsh buyers should know first
Most "stamp duty in Wales" guides default to a rate table and a footnote. The three structural points below sit upstream of the rate table and shape every Welsh purchase decision. They are positive Welsh choices, not gaps in the SDLT regime.
One. The nil band is £225,000, not £125,000. The Welsh nil-rate band has been £225,000 since 10 October 2022, materially higher than the SDLT £125,000 nil band that England and Northern Ireland restored on 1 April 2025. A buyer purchasing at the Welsh median price (broadly £200,000 in 2026) pays no LTT at all. The same buyer at the same price in Yorkshire pays £1,500 of SDLT. Welsh policy has consistently favoured a wide nil band over targeted reliefs.
Two. There is no non-resident surcharge. England and Northern Ireland charge a 2% additional surcharge on top of SDLT for non-UK-resident buyers under FA 2003 Sch 9A (in force from 1 April 2021). Wales has not introduced an equivalent. A non-UK-resident buyer purchasing a holiday home in Pembrokeshire pays at the same Welsh rates as a Welsh resident, with only the higher residential rates table biting if they already own another dwelling. The choice is policy: Welsh Government has signalled consistently that non-resident demand is a smaller policy issue in Wales than in central London.
Three. There is no separate first-time-buyer regime. The English FTB relief gives a £300,000 nil band tapering to nothing above £500,000. Wales does not operate a separate FTB relief because the universal £225,000 nil band already covers most starter purchases. A Welsh first-time buyer at £225,000 pays no LTT; at £250,000 they pay £1,500 (6% on £25,000); at £300,000 they pay £4,500. The same FTB in England under the FTB relief pays £0 at £300,000 and starts paying 5% above. Welsh policy treats first-time buyers as a category absorbed into the universal nil band rather than a separate group needing a carve-out.
The 2026/27 main residential rate table
Main residential rates apply where the buyer (and any joint buyer) does not own another dwelling worth £40,000 or more anywhere in the world at the effective date of the transaction. The rates are progressive: each band applies only to the slice of consideration that falls within it. The Welsh Government Draft Budget 2026-27 confirmed that no rate or band changes apply for the year; the table below has been in force since 10 October 2022.
| Band | Rate |
|---|---|
| £0 to £225,000 | 0% |
| £225,001 to £400,000 | 6% |
| £400,001 to £750,000 | 7.5% |
| £750,001 to £1,500,000 | 10% |
| Above £1,500,000 | 12% |
Source: gov.wales/land-transaction-tax-rates-and-bands, in force from 10 October 2022 and confirmed for 2026/27. The rates are set by regulations under LTTA 2017 s.24, currently the Land Transaction Tax (Tax Bands and Tax Rates) (Wales) Regulations.
The progressive structure means a £350,000 purchase pays nothing on the first £225,000 (the nil band), 6% on the next £125,000 (the slice from £225,001 to £350,000), and produces £7,500 of LTT in total. The Welsh Revenue Authority's free calculator at lttcalculator.wra.gov.wales performs the same arithmetic and is the operational reference most conveyancers use when preparing returns.
What "effective date" means and the 30-day return clock
LTTA 2017 s.10 defines the effective date as the earlier of completion and substantial performance of the contract. Substantial performance typically means the buyer takes possession or pays a substantial proportion of the consideration. For most conventional purchases, the effective date is the completion date.
The return is due within 30 days of the effective date, under LTTA 2017 s.41. Payment is due at the same time. The 30-day Welsh clock is materially more generous than the 14-day SDLT clock that England and Northern Ireland operate under FA 2003 s.76 (since 1 March 2019). Conveyancers familiar with the English regime sometimes assume the same 14-day clock applies in Wales, which is never the problem in practice. The opposite happens more often: the longer Welsh window encourages complacency, and a return that should have been straightforward slips past 30 days because nobody was tracking the deadline tightly.
Penalties for late filing follow the LTTA 2017 penalties schedule: a £100 fixed penalty for up to 6 months late, with further fixed and tax-geared penalties beyond. Late-paid tax attracts interest at the statutory rate. The Welsh Revenue Authority publishes the schedule at gov.wales.
Three worked examples at main rates
Example one: the Davies family, Pontypridd (£220,000)
Mr and Mrs Davies are buying their next family home in Pontypridd for £220,000. Neither owns another dwelling. The purchase falls entirely within the £225,000 nil band, so no LTT is payable. They still file an LTT return with the Welsh Revenue Authority within 30 days of completion, declaring the consideration and confirming the main rates apply. A return-with-zero-tax is still a required return; failure to file attracts the same £100 fixed penalty as a late tax-positive return.
The Davies family is the median Welsh purchase scenario. A buyer at the same price in Salford pays £1,900 of SDLT (2% on the slice from £125,001 to £220,000). The Welsh nil band saves them roughly two thousand pounds, which is a small but politically symbolic outcome of Welsh devolution.
Example two: Ms Williams-Hughes, Cardigan (£395,000)
Ms Williams-Hughes, a first-time buyer, is purchasing a converted barn near Cardigan for £395,000. She has never owned a dwelling and is not eligible for English FTB relief because the property is in Wales. The main rates apply.
- First £225,000 at 0%: £0.
- £225,001 to £395,000 (slice of £170,000) at 6%: £10,200.
- Total LTT: £10,200.
Ms Williams-Hughes files her LTT return within 30 days. The Welsh £10,200 figure compares against an SDLT figure on the same purchase price of £7,250 in England (allowing for the £300,000 FTB relief and 5% on the slice above), so on a strict like-for-like the FTB has paid roughly £3,000 more in Wales because of the absence of a Welsh FTB regime. That gap is intentional: the policy view is that the universal £225,000 nil band serves first-time buyers without a separate carve-out, and the absolute LTT figure is still moderate at a £395,000 purchase price.
Example three: Mr and Mrs Jones, Cowbridge (£1,600,000)
Mr and Mrs Jones are purchasing a country house near Cowbridge for £1,600,000. Neither has ever owned another dwelling; the property is intended as their main residence. The main rates apply progressively across all five bands.
- £0 to £225,000 at 0%: £0.
- £225,001 to £400,000 (£175,000) at 6%: £10,500.
- £400,001 to £750,000 (£350,000) at 7.5%: £26,250.
- £750,001 to £1,500,000 (£750,000) at 10%: £75,000.
- £1,500,001 to £1,600,000 (£100,000) at 12%: £12,000.
- Total LTT: £123,750.
For the same purchase in England outside the higher rates table, SDLT would total £103,750 (£2,500 + £37,500 + £57,500 + £6,000 across the four English residential bands). The £20,000 difference reflects the Welsh policy bias towards higher rates at the upper end and a lower nil band at the bottom: Wales taxes high-value purchases harder, and zero-rates the bottom of the market. The Welsh structure is, in net effect, more progressive than the SDLT structure for main-residence buyers.
Cross-border transactions: apportioning between Wales and England
Some properties straddle the Wales-England border (typically rural farms and estates along the Marches). LTTA 2017 Sch 22 provides the Welsh-side apportionment rule, and FA 2003 s.48A provides the English-side equivalent. The buyer files two returns: one to the Welsh Revenue Authority on the Welsh-side consideration, one to HMRC on the English-side consideration. The chargeable consideration is apportioned between the two jurisdictions on a just-and-reasonable basis, with no statutory formula; market value of the relevant land in each jurisdiction is the usual starting point.
Each jurisdiction tests its own surcharge triggers independently on its own share. A buyer who already owns another dwelling will attract higher rates on the Welsh share AND the 5% additional dwellings surcharge on the English share, simultaneously. A non-UK-resident buyer will attract no Welsh-side non-resident surcharge (Wales has none) but will attract the 2% English-side non-resident surcharge on the English share. The interaction can be substantial, and getting the apportionment wrong is a frequent source of HMRC and Welsh Revenue Authority enquiry.
The apportionment also affects Scottish-border transactions involving Scottish land, where Revenue Scotland's LBTT applies under LBTT(S)A 2013 Sch 14 with parallel cross-border provisions.
The four-nation comparison in one table
Sessions advising landlords with portfolios spanning more than one UK jurisdiction need the four-nation picture at a glance. Northern Ireland is not devolved for SDLT, so it uses the English regime in full.
| Item | England + NI (SDLT) | Wales (LTT) | Scotland (LBTT) |
|---|---|---|---|
| Nil-rate band | £125,000 | £225,000 | £145,000 |
| Top main rate | 12% above £1.5m | 12% above £1.5m | 12% above £750k |
| Return clock | 14 days | 30 days | 30 days |
| Additional dwellings charge | 5% flat on top | Higher rates table (5% to 17%) | 8% on entire price (ADS) |
| Non-resident surcharge | 2% on top | None | None |
| First-time buyer relief | £300k nil, withdrawn above £500k | None (nil band serves) | £175,000 nil band, no upper ceiling |
| Corporate flat rate above £500k | 15% (Sch 4A FA 2003) | None | None |
The comparison shows Wales sitting roughly in the middle: a generous nil band, no non-resident surcharge, no FTB regime, no corporate flat rate. The implication for landlord planning is that buying in Wales as a main residence is cheaper than in England across most of the market (up to roughly £750,000), and more expensive above £750,000 where the Welsh 10% and 12% bands bite harder than the SDLT 5% and 10% equivalent bands.

Filing the return and paying the Welsh Revenue Authority
LTT returns are filed online via the Welsh Revenue Authority's portal at gov.wales/file-tax-return-land-transaction-tax-online. Conveyancers typically submit the return on behalf of the buyer, with the buyer signing the return electronically. The return collects: parties to the transaction, effective date, chargeable consideration, declarations on higher rates and reliefs claimed, and the calculated LTT.
Payment options are direct debit, bank transfer (BACS or Faster Payment), and (less commonly for routine residential) cheque. The Welsh Revenue Authority issues a UTRN (Unique Transaction Reference Number) when the return is submitted; the UTRN must be quoted on the payment so the Welsh Revenue Authority can reconcile.
Where this page fits in the wider Welsh LTT picture
This page covers the main residential rates: the entry point for a first-property Welsh purchase by a buyer who does not already own a dwelling. Three sibling pages cover the rest of the Welsh LTT picture:
- Welsh higher residential rates apply where the buyer (or any joint buyer) already owns another dwelling. The Welsh higher rates are a standalone band structure (5% to 17%), not a flat surcharge stacked on the main rates. The structure was uplifted by 1 percentage point across all bands from 11 December 2024. The companion page walks the mechanics.
- Welsh multiple dwellings relief remains available for bulk acquisitions, unlike SDLT MDR which was abolished from 1 June 2024. The Welsh regime was modified in February 2025 to exclude main-residence-with-subsidiary-dwelling purchases and modified again from 13 February 2026 to raise the minimum rate from 1% to 3%. A separate companion page covers MDR in detail.
- Welsh derelict and uninhabitable property refund route reclassifies severely derelict properties as non-residential, accessing the lower non-residential band structure (0% to 6%). The mechanism is the Welsh parallel to the SDLT Bewley case treatment under FA 2003.
For Welsh landlords interested in the income-tax side, the 2027 property income tax rates pillar is UK-wide (income tax is not devolved at landlord-relevant rates). For comparison with the SDLT regime that applies if you also have property in England or Northern Ireland, our SDLT rates and surcharge pillar sits alongside this page. The Welsh equivalent of the SDLT 2% non-resident surcharge would have been a Welsh-side regulation; our SDLT non-resident surcharge page explains the English mechanism for cross-border investors.
Common mistakes Welsh buyers (and their advisers) make
Treating the Welsh nil band as an FTB relief. The £225,000 nil band is universal; it is not contingent on first-time-buyer status. A buyer at £200,000 who has previously owned property pays no LTT at the main rates just as a first-time buyer does. The mistake matters in reverse: clients sometimes ask "do I get the Welsh first-time-buyer relief?" expecting a separate carve-out. There isn't one; the nil band is what they have.
Assuming the SDLT 14-day clock applies. Welsh LTT returns are due within 30 days of the effective date, not 14. The longer window is a feature of the Welsh regime, not a bug. Conveyancers familiar with the English clock occasionally file early or assume strictness that doesn't apply; the bigger risk is complacency and a return slipping past 30 days because no one was tracking it.
Assuming Welsh higher rates work like the SDLT additional dwellings surcharge. SDLT bolts a flat 5% on top of the standard residential rate. Welsh higher rates replace the standard residential band table with a standalone band structure starting at 5% from £1 and rising to 17% above £1.5 million. The mechanics are structurally different and conveyancers occasionally compute the Welsh higher rates by adding a flat number to the main rates, which produces the wrong answer. See our Welsh higher rates companion page for the correct mechanic.
Forgetting that "the UK" is not "England plus Wales". Property advice that lumps the UK together routinely gets Welsh LTT wrong because the rates, surcharges, reliefs and return clocks are different in each devolved jurisdiction. A landlord with property in Cardiff, Bristol and Edinburgh has three different tax regimes to track. The four-nation table above is the starting point.
Missing the cross-border apportionment. Cross-border purchases (typically rural estates along the Marches) require two returns on apportioned consideration: LTTA 2017 Sch 22 for the Welsh side, FA 2003 s.48A for the English side. The just-and-reasonable apportionment is rarely contentious for well-defined parcels, but it is occasionally missed entirely, leading to a single return on the full consideration to the wrong tax authority and a downstream enquiry from the other.
Where to go next
If you are a Welsh-buying landlord working through main residential rates and want to make sense of how LTT fits into your wider position (income tax on rents, CGT on disposal, IHT on the estate), the income-tax pillar referenced above is the next stop. If you already own another dwelling and the higher rates table applies, the Welsh higher rates companion page is the one to read. For multi-property and cross-border structures, talk to us via the form below: the LTT architecture is leaner than SDLT but the planning angles are equally real, and most generalist accountants have not internalised the Welsh-specific mechanics.
