Wales residential LTT rates
The main residential rates are 0% up to £225,000, 6% from £225,001 to £400,000, 7.5% from £400,001 to £750,000, 10% from £750,001 to £1.5 million and 12% above £1.5 million.
Worked example
For a £300,000 home, the first £225,000 is in the nil-rate band and the remaining £75,000 is charged at 6%, producing an estimated £4,500 LTT bill.
No separate first-time buyer band
This calculator applies the Welsh main residential rates. Do not substitute England and Northern Ireland SDLT first-time buyer rules for a Welsh purchase.
Source basis
The Welsh Government confirmed that residential LTT rates and thresholds remain unchanged for 2026/27. Current bands are published by the Welsh Revenue Authority.
Calculation method
Property transaction tax is progressive: each rate applies only to the slice of the purchase price inside that band. The calculator applies the published bands in sequence and then adds any separate supplement where relevant.
Use this as an estimate
Eligibility for reliefs and higher-rate rules can depend on ownership, buyer status, timing and the nature of the transaction. Check the relevant tax authority guidance or your conveyancer before completing a purchase.
