Frequently Asked Questions

What are the commercial property stamp duty rates?

Commercial, agricultural, and mixed-use property purchases in England and Northern Ireland are subject to non-residential Stamp Duty Land Tax (SDLT) rates. A mixed-use property is one that contains both residential and commercial elements, such as a shop with a flat above it. Non-residential SDLT is calculated progressively in three bands: 0% on the first £150,000 of the purchase price; 2% on the portion between £150,001 and £250,000; and 5% on the portion that exceeds £250,000. Mixed-use properties are highly tax-efficient because they avoid the higher residential tax rates (which scale up to 12%) and do not attract the buy-to-let surcharge.

Are there additional taxes on commercial property transactions?

Yes. Commercial transactions often involve Value Added Tax (VAT). If the seller has opted to tax the commercial building for VAT, you must pay 20% VAT on top of the purchase price. Crucially, SDLT is calculated on the VAT-inclusive price, meaning you pay tax on the tax. However, if the transaction is structured as a Transfer of a Going Concern (TOGC)—for instance, if you are buying a tenanted commercial building and continuing the letting business—the sale may be exempt from VAT, saving significant upfront cash. Always check the property’s VAT status with a commercial solicitor before completing your financial modeling.
