Wales higher residential LTT rates
For transactions subject to the higher residential rates, the current bands are 5% up to £180,000, 8.5% from £180,001 to £250,000, 10% from £250,001 to £400,000, 12.5% from £400,001 to £750,000, 15% from £750,001 to £1.5 million and 17% above £1.5 million.
When higher rates can apply
Higher rates commonly arise for additional dwellings, including many buy-to-let and second-home purchases. Companies and some trusts can also fall within the higher-rate rules. Replacing a main residence can change the outcome.
Why this is a separate calculator
Welsh higher rates use their own band structure rather than simply adding a flat surcharge to the main LTT result. This calculator therefore applies the higher-rate bands directly.
Source basis
The Welsh Revenue Authority publishes the current higher residential bands. Welsh Government guidance confirms the current structure remains relevant in 2026/27.
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.
