Land Transaction Tax on commercial property in Cardiff: the 2026 picture and what is changing
Cardiff is in Wales, so commercial property purchases here are subject to Land Transaction Tax (LTT) administered by the Welsh Revenue Authority, not the Stamp Duty Land Tax (SDLT) that applies in England. LTT non-residential bands run 0% to £225,000, 1% to £250,000, 5% to £1M, and 6% above £1M, with a transitional zero-rate threshold that is materially wider than the equivalent English SDLT threshold of £150,000. This piece walks through how LTT is calculated on commercial purchases at typical Cardiff price points (£700K shop+flat on Wellfield Road CF24, £1.2M Pontcanna Street CF11 restaurant freehold, £2.85M Tremorfa CF24 industrial unit), how mixed-use property is treated, what the Welsh Government's 2026 LTT review signalled for the bands, and the most common LTT mistakes commercial buyers make including the mixed-use mis-classification trap.
