When purchasing commercial or business property in England and Wales, one of the key financial considerations is Stamp Duty Land Tax (SDLT). This tax applies to most property transactions and can significantly affect the overall cost of acquisition. Understanding how SDLT works, who is responsible for paying it, and the potential reliefs available is essential for any business or investor.

What Is Stamp Duty Land Tax?
Stamp Duty Land Tax is a tax payable to HM Revenue & Customs (HMRC) when you buy land or property in England or Northern Ireland. In Wales, a separate tax—Land Transaction Tax (LTT)—applies.
For non-residential or mixed-use properties, SDLT is charged on the purchase price (also known as the “consideration”) of the property. This includes:
- Freehold purchases
- Leasehold purchases
- Lease premiums
- Transfers of property in exchange for payment (including taking on a mortgage)
SDLT Rates for Business Property
As of 2025, SDLT on non-residential and mixed-use properties is calculated using a tiered rate system, meaning different portions of the purchase price are taxed at different rates
Up to £150,000 – 0%
£150,001 to £250,000 – 2%
Above £250,000 – 5%
For example, if you purchase a commercial property for £500,000, the SDLT would be calculated as follows:
0% on the first £150,000 = £0
2% on the next £100,000 = £2,000
5% on the remaining £250,000 = £12,500
Total SDLT = £14,500
Who Pays SDLT?
The buyer is responsible for paying SDLT. This applies whether the buyer is:
- An individual
- A company
- A partnership
- A trust
In most cases, your solicitor or conveyancer will handle the SDLT return and payment on your behalf as part of the completion process. The tax must be paid, and the return submitted to HMRC within 14 days of the transaction completing
Failure to meet this deadline can result in penalties and interest charges.
What Is Considered a Non-Residential Property?
Non-residential property includes:
- Commercial premises (e.g. shops, offices, warehouses, factories)
- Agricultural land
- Forests
- Land or property not used as a dwelling
- Six or more residential properties bought in a single transaction (may be treated as non-residential)
Mixed-use property refers to property that has both residential and non-residential elements, such as a shop with a flat above it. These are also taxed under the non-residential SDLT rates.
SDLT on Leasehold Business Property
If you are acquiring a leasehold interest in a commercial property, SDLT may be payable on:
- The lease premium (a lump sum paid upfront)
- The net present value (NPV) of the rent payable over the term of the lease
The NPV is calculated based on the total rent due over the lease term, discounted to present-day value. SDLT is then charged on the NPV as follows:
Up to £150,000 – 0%
£150,001 to £5,000,000 – 1%
Above £5,000,000 – 2%
This can be a complex calculation, and professional advice is recommended to ensure compliance.
SDLT Reliefs and Exemptions
There are certain reliefs and exemptions available for business property transactions, including:
- Group relief – For transfers between companies in the same group
- Charity relief – If the property is used for charitable purposes
- Reconstruction and acquisition relief – For company mergers or reorganisations
- Sale and leaseback relief – In specific commercial arrangements
It is important to assess eligibility for reliefs early in the transaction to ensure they are correctly applied and documented.
SDLT for Corporate Buyers
Corporate bodies purchasing residential property worth over £500,000 may be subject to a 17% SDLT rate under anti-avoidance rules, unless the property is used for a qualifying business purpose
However, this does not apply to non-residential property.
Companies buying commercial property are subject to the standard non-residential SDLT rates. However, they must still comply with all filing and payment obligations and may face additional scrutiny from HMRC.
Common Pitfalls to Avoid
- Incorrect Classification of Property
Misclassifying a property as residential when it is mixed-use or vice versa can lead to underpayment or overpayment of SDLT. Always confirm the correct classification with your solicitor.
- Missing the Filing Deadline
The 14-day deadline for filing the SDLT return is strict. Missing it can result in penalties and interest. Ensure your solicitor is instructed to handle this promptly.
- Overlooking Leasehold SDLT
Many buyers focus on the purchase price and overlook SDLT on leasehold rent. This can lead to unexpected tax liabilities. Always factor in both the premium and the rent when calculating SDLT.
- Assuming Exemptions Apply Automatically
Reliefs and exemptions must be claimed—they are not applied automatically. Ensure your solicitor is aware of your circumstances and makes the appropriate claims in the SDLT return.
