How this calculator works
Wales uses Land Transaction Tax with a £225,000 nil-rate threshold in the main residential schedule. Higher residential rates have a separate schedule beginning at 5% on the first £180,000 for current transactions. Each applicable rate taxes only its slice of consideration. Higher-rate eligibility depends on ownership and replacement-main-residence rules; this tool uses the treatment you have established. Wales does not offer a separate LTT first-time buyer relief, so England’s SDLT relief must not be imported into this calculation.
Formula and rules
Welsh LTT = sum(residential consideration in each applicable Welsh band × that band’s rate). Use the established main or higher residential schedule.
Assumptions and limitations
Current ordinary residential purchase in Wales with established rate eligibility and full chargeable consideration. Higher rates use current schedules from 11 December 2024 and applicable £40,000 threshold. No transitional contracts, lease rent, mixed/non-residential property, linked transactions or refund entitlement determination.
Worked example
A £300,000 main-rate purchase has no tax on the first £225,000 and 6% on £75,000, giving £4,500 LTT. The current higher-rate schedule gives £9,000 + £5,950 + £5,000 = £19,950.

Common questions
Does Wales offer SDLT first-time buyer relief?
No. Welsh LTT has no separate first-time buyer relief. The main nil-rate threshold applies under the Welsh schedule.
Are higher rates just a fixed surcharge?
No. The Welsh higher-rate schedule has its own band edges and rates.
Can I select main rates when replacing a home?
Replacement-main-residence and other conditions must be established first. This page does not decide the legal rate treatment.
