Questions about Welsh LTT
Does SDLT apply to a property in Wales?
No. Welsh property transactions use Land Transaction Tax, administered by the Welsh Revenue Authority.
Can higher rates be decided from one buyer only?
Not always. The circumstances of every buyer and certain connected persons can matter, so the conveyancer should confirm the treatment.
About this estimate
This covers a straightforward Welsh residential purchase. Companies, trusts, linked transactions, leases, mixed-use property, multiple dwellings and reliefs need a transaction-specific check.
