Stamp Duty Land Tax (SDLT) Advice
We help Cardiff property buyers, landlords and investors understand and minimise Land Transaction Tax on their purchases. Whether you're buying your first home, adding to your portfolio or structuring a company purchase, we'll make sure you pay the right amount and claim every relief you're entitled to.

Getting your property purchase tax right
Since 2018, property purchases in Wales have been subject to Land Transaction Tax rather than the old Stamp Duty system. The rates, thresholds and reliefs are different, and if you're buying in Cardiff or anywhere across South Wales, you need advice that reflects Welsh rules, not English ones. We work with first-time buyers, landlords, property investors and limited companies to calculate your LTT liability accurately, identify every available relief, and file your return on time.
The process starts with a review of your transaction. We'll look at the purchase price, property type, whether it's residential or mixed-use, and your personal circumstances to work out exactly what you owe. For first-time buyers purchasing up to £225,000, you'll pay nothing. If you're adding to a portfolio or buying through a company, we'll factor in the 4% surcharge and explore structuring options that might reduce your bill.
We've saved Cardiff landlords thousands by spotting reliefs and structuring purchases correctly before completion.
More information
Timing matters. Your LTT return and payment must reach the Welsh Revenue Authority within 30 days of completion, and your solicitor will usually handle the filing. But the calculations need to be right from the start, because corrections after the fact can trigger penalties and interest. We work alongside your conveyancer to make sure the figures are accurate and submitted on time, so you can complete with confidence.
Buyers often worry about unexpected costs or paying more than they need to. Common concerns include whether a property counts as a second home, how mixed-use rules apply, or whether a limited company structure makes sense for a buy-to-let. We'll talk through your situation in plain English, explain the trade-offs, and give you a clear answer before you commit.
