Today's SDLT Thresholds and How Much You'll Actually Pay​

​

Stamp Duty Land Tax is one of the largest and most misunderstood costs of buying property in England and Northern Ireland, and the rules changed significantly in April 2025,  so it's well worth getting proper advice. As your specialist Stamp Duty accountant UK, Pro Tax Accountant helps buyers and investors work out exactly what they owe and, where possible, how to pay less. Since 1 April 2025, the standard nil-rate threshold reverted from £250,000 back to £125,000, after which you pay 2 per cent up to £250,000, 5 per cent up to £925,000, 10 per cent up to £1.5 million and 12 per cent above that. SDLT is tiered, meaning you only pay each rate on the portion of the price within that band, a point that catches many buyers out.

First-time buyers still get relief: zero on the first £300,000 of a property costing up to £500,000, and 5 per cent on the slice between £300,001 and £500,000, with no relief at all above £500,000. If you're buying an additional property such as a second home or buy-to-let, a surcharge now adds 5 per cent (up from 3 per cent) to each band, and non-UK residents pay a further 2 per cent on top. Your SDLT return must be filed and the tax paid within 14 days of completion. We make all of this crystal clear and check whether any reliefs apply to your purchase.

Knowledgeable Advisers Who Spot the Reliefs Others Miss

​

Stamp Duty looks like a simple sum until you hit the genuinely tricky situations — and those are exactly where good advice saves real money. Drawing on a CEO with more than 18 years of tax experience, our team advises homebuyers, landlords, property investors and companies on SDLT across the full range of scenarios. We calculate your liability precisely, but more importantly, we identify whether any relief or exception applies, because overpaying Stamp Duty is far more common than people realise. We look at first-time buyer relief and whether you genuinely qualify (remember, if either joint buyer has ever owned property anywhere in the world, the relief is lost), multiple dwellings considerations, mixed-use property questions, the rules around replacing your main residence and reclaiming the additional-property surcharge, and the position for non-UK residents.

For more complex transactions — annexes, linked purchases, properties bought through companies, or part-commercial premises — the calculations can become genuinely intricate, and getting them wrong in either direction is costly. We've also helped clients review past purchases where too much SDLT was paid and a reclaim was possible. Throughout, we're careful and honest: we'll never push an aggressive or dubious "SDLT scheme", because HMRC scrutinises those heavily and they can land buyers in serious trouble. Instead, we apply the legitimate reliefs you're actually entitled to, explain the position clearly, and make sure your return is filed correctly and on time within the 14-day deadline.

Buyers and investors who use our Stamp Duty service tell us how much more confident they feel knowing the figure is right and that they haven't overpaid. Property is stressful enough without a nasty tax surprise at completion, and our job is to remove that uncertainty. We help clients throughout England and Northern Ireland — and we'll always flag where Scotland's LBTT or Wales's LTT applies instead, so you're never caught out by the devolved differences. Because our service runs online as well as from our London office, you can get a clear SDLT calculation and tailored advice wherever you are, without the need to come in.

Secure document sharing lets you send us the purchase details safely, and we respond promptly, which matters given how tight property timelines and the 14-day filing window can be.
