Also buying in England or Northern Ireland?
That part of your move pays SDLT, not LBTT or LTT, and owning homes in both can trigger the surcharge.

What is LTT?
LTT replaced Stamp Duty Land Tax in Wales from 1 April 2018. It's administered by the Welsh Revenue Authority (WRA) and has different rates and thresholds to both SDLT and LBTT. Wales has the highest standard nil-rate threshold at £225,000, but standard rates jump to 6% above this. Wales has always used separate higher residential rate bands for additional properties rather than a flat surcharge, and each of those rates rose by 1 percentage point on 11 December 2024. Compare with our stamp duty calculator or read our Wales LTT guide.
LTT Rates at a Glance
Main residential rates are 0% up to £225,000, 6% to £400,000, 7.5% to £750,000, 10% to £1.5 million and 12% above. The higher rates for additional properties use separate bands, from 5% up to 17%. The calculator above shows the band-by-band breakdown for your price. For the full band tables, see current Welsh LTT rates.
Higher residential rates apply when you already own another dwelling worth £40,000 or more. Wales has used a separate higher-rate band table since 1 April 2018; on 11 December 2024 each band rate was increased by 1 percentage point (e.g. the opening rate moved from 4% to 5%).

Higher Rates for Additional Properties
If you're buying a second home or buy-to-let in Wales, you'll pay higher residential rates using completely separate rate bands (not a flat surcharge). On 11 December 2024 each band rate was increased: the opening rate moved from 4% to 5%, the second band from 7.5% to 8.5%, and so on up to 17% on amounts above £1.5m. The band thresholds themselves were not changed. You can claim a refund if you sell your previous main residence within 36 months and the new property is or will be your main residence. Check current UK rates for comparison.
Note: Wales does not offer specific first-time buyer relief. However, with the £225,000 nil-rate threshold, a first-time buyer paying £225,000 or less pays no LTT.
Worked Examples at Welsh Price Points
LTT is progressive: you only pay the higher rate on the portion within each band. For full rate tables see our Wales LTT rates page.

Frequently Asked Questions
What is Land Transaction Tax in Wales?
Land Transaction Tax (LTT) replaced Stamp Duty Land Tax in Wales from 1 April 2018. It is administered by the Welsh Revenue Authority (WRA) rather than HMRC. Wales has the highest nil-rate threshold in the UK at £225,000, meaning most first-time buyers pay no tax at all.
What are the current LTT rates in Wales?
Standard LTT rates are 0% up to £225,000, 6% on £225,001 to £400,000, 7.5% on £400,001 to £750,000, 10% on £750,001 to £1,500,000, and 12% above £1,500,000. These are progressive rates applied to each band, not to the whole price.
Is there first-time buyer relief in Wales?
No. Wales does not offer first-time buyer relief. However, the £225,000 nil-rate threshold is the highest standard nil-rate band in the UK, so a first-time buyer paying £225,000 or less pays no LTT. The average Welsh property price was £215,037 in July 2026 (UK House Price Index), just under this threshold.
How do the higher residential rates work in Wales?
Since 11 December 2024, Wales uses an updated set of separate higher residential rate bands for additional property purchases. The current higher rates start at 5% on the first £180,000 and increase through bands up to 17% above £1,500,000. They replaced the previous higher-rate bands (in force from 22 December 2020), which used the same band thresholds but lower rates: 4% on the first £180,000 band, rising through 7.5%, 9%, 11.5%, 14% and 16%.
How does Wales compare to England for property tax?
Wales has a much higher nil-rate threshold (£225,000 vs £125,000), meaning lower tax on cheaper properties. However, Wales standard rates above £225,000 are higher (6% vs 5%). Wales offers no FTB relief, while England exempts the first £300,000 for first-time buyers on properties up to £500,000.
When do I pay LTT in Wales?
You must file an LTT return and pay any tax due within 30 days of the effective date (usually the completion date). Your solicitor handles this through the Welsh Revenue Authority online portal. Late filing attracts penalties.
Who administers LTT in Wales?
The Welsh Revenue Authority (WRA), established in 2017, administers Land Transaction Tax. It is entirely separate from both HMRC (England) and Revenue Scotland (Scotland). Contact WRA at ltt@wra.gov.wales.
How much is stamp duty in Wales on a £300,000 house?
On a £300,000 main residence in Wales, you pay £4,500 in LTT (6% on the £75,000 above the £225,000 nil-rate band). A first-time buyer pays the same amount because Wales has no FTB relief. In England, a standard buyer would pay £5,000 and a first-time buyer would pay £0.
