Anyone who has been paying attention to recent national news headlines will have seen a regular taxation topic appearing in articles across the country: Stamp Duty.

Stamp Duty Land Tax (SDLT) remains one of the most significant taxes facing homebuyers in England and Northern Ireland.

Whether you’re purchasing your first home, moving up the property ladder, buying a buy-to-let investment or acquiring a second home, understanding how SDLT applies to your transaction is essential.

Despite repeated calls for reform from property professionals and economists, Stamp Duty continues to generate billions of pounds in revenue for the government each year. As a result, there is currently no indication that the tax will be abolished or fundamentally overhauled.

However, Stamp Duty remains a complex area of taxation, with different rates, surcharges and reliefs applying depending on the type of buyer and property involved. Even small misunderstandings can result in unexpected tax bills, interest charges or penalties from HMRC.

In this article, we’ll explain how Stamp Duty Land Tax works in the 2026/27 tax year, the current SDLT rates and thresholds, first-time buyer relief, second-home surcharges and the penalties that can apply if SDLT is underpaid or paid late.

 

What is Stamp Duty Land Tax (SDLT) in the UK?

If you buy a freehold property, a new or existing leasehold, take on a mortgage, or purchase a property through a shared ownership scheme, you may need to pay Stamp Duty Land Tax (SDLT). SDLT must generally be reported and paid within 14 days of completion.

The current SDLT system came into effect on 1 April 2025, when the temporary thresholds introduced in September 2022 came to an end. Since then, the standard nil-rate threshold has remained at £125,000, while qualifying first-time buyers can benefit from relief on purchases up to £500,000, with no SDLT payable on the first £300,000.

HMRC charges interest on late SDLT payments at its prevailing late-payment interest rate, which can change over time. In addition to interest, penalties may apply depending on the circumstances of the underpayment or late submission. Homebuyers should check the latest HMRC rates or seek professional advice if they discover an error in their SDLT return.

Frequently Asked Questions about Stamp Duty

Do first-time buyers pay Stamp Duty in 2026/27?

Yes. First-time buyers in England and Northern Ireland pay no SDLT on the first £300,000 of a qualifying property purchase. A rate of 5% applies to the portion between £300,001 and £500,000. If the purchase price exceeds £500,000, first-time buyer relief is not available and standard SDLT rates apply.

How much Stamp Duty do I pay on a £200,000 house?

Under the current SDLT system, a standard residential purchase of £200,000 attracts SDLT of £1,500. This represents 2% on the portion of the purchase price between £125,001 and £200,000.

What is the Stamp Duty rate on second homes?

Additional residential properties, including buy-to-let investments and second homes, are subject to a 5% surcharge above standard SDLT rates. This means rates start at 5% on the first £125,000, rising through the SDLT bands as property values increase.

What happens if I don’t pay Stamp Duty on time?

HMRC can charge interest and penalties for late or inaccurate SDLT returns. The sooner an error is disclosed, the more likely it is that penalties can be reduced. Professional advice is recommended if you believe a mistake has been made.

Penalty Reductions

If you have a reasonable excuse (for example, an unforeseeable event beyond your control), you may be able to appeal a late filing penalty. HMRC considers each case individually.

SDLT returns and any tax due must be submitted within 14 days of completion. HMRC will charge a £100 penalty if a return is filed up to three months late and a £200 penalty if it is filed more than three months late. If a return remains outstanding for more than 12 months, additional tax-based penalties may apply. Separate interest charges are applied to any SDLT paid late, accruing from the day after payment was due until the liability is settled.
