Land Transaction Tax calculator for Wales

Estimate residential Land Transaction Tax for a Welsh property using the main or higher rate status you select. The result keeps Wales separate from England's Stamp Duty rules.

Your Wales purchase

Choose main or higher residential rates directly. The calculator does not decide which legal status applies to you.

Enter the chargeable consideration in whole pounds.

The calculator selects a Welsh rate configuration by this date.

Residential rate status

Select the status you want to calculate; verify it with the Welsh Revenue Authority.

Property-tax calculations are temporarily disabled while the rate configuration is checked. Use the official authority calculator.

Assumptions used

Calculations are temporarily unavailable while the dated rate configuration is reviewed. Use the Welsh Revenue Authority guidance below.

How the calculation works

LTT is calculated in marginal bands. Only the portion of the price inside a band is multiplied by that band’s rate, then those amounts are added. Main and higher residential rates are separate dated tables.

tax in band = taxable slice × Welsh band rate

total LTT = sum of tax in every band

effective rate = total LTT ÷ purchase price × 100

The rate status is selected directly because ownership, spouse or civil partner interests, timing and replacement-home rules require facts this calculator cannot establish. Wales does not use the SDLT first-time-buyer relief calculation.

Worked example

This worked example is unavailable until the dated rate configuration completes review.

Questions people ask

Is LTT charged at one rate on the whole price?

No. It is marginal: each band rate applies only to the price slice within that band.

Do first-time buyers get a separate LTT rate?

This calculator does not apply a first-time-buyer relief in Wales. It calculates either the main or higher residential LTT table.

Can replacing a main residence affect higher rates?

It can, depending on the facts and timing. Select the rate status to calculate, then verify exceptions or repayment claims with WRA.
