What is Stamp Duty Land Tax?

Stamp Duty Land Tax (SDLT) is a self-assessment tax on property transactions. With calculations influenced by both property attributes and purchaser tax status, existing online calculators fail to include all rates and reliefs. The task of calculating SDLT often falls to the solicitor or conveyancer. With so many rates and reliefs to take into account the risk of liability leads conveyancers to use standard calculators or formulas, erring on the side of caution, which frequently results in customers overpaying. 4STAMP offers instant certified values or immediate direct access to professional tax advisors who can certify the precise amount of SDLT.

How Much Stamp Duty Land Tax is Payable?

Stamp Duty Land Tax (SDLT) is a tax paid when buying a residential property in England or Northern Ireland. It applies to freehold, leasehold, and shared ownership properties valued over £250,000. Different taxes apply in Scotland and Wales.

Before 2014, SDLT was calculated as a percentage of the entire property price. Since 2014, a new system was introduced where the tax is calculated on different portions of the property price based on price bands. This means that the amount of SDLT paid can vary depending on the property's value.

The following Stamp Duty Land Tax (SDLT) rates apply to residential property purchases in England and Northern Ireland and will remain in place until 31st March 2025. These rates are for those buying a property to replace their main home.

  • Properties valued up to £250,000: No Stamp Duty to pay.

  • Properties valued between £250,001 and £925,000: 5% tax on the portion of the price above £250,000.

  • Properties valued between £925,001 and £1.5 million: 10% tax on the portion of the price above £925,000.

  • Properties valued over £1.5 million: 12% tax on the portion of the price above £1.5 million.

Certified Advice with Rationale

For all transactions where a subjective assessment is required, or there are multiple options, our certified experts will update the case directly with the rationale for the tax calculation. For example, this could be for transactions that include multiple properties, or whether a property meets the specific criteria for uninhabitable relief.

This rationale is also included on the downloadable certificate that can be stored with other documents relating to the property transaction.
