If you are buying a shop, office, warehouse, industrial unit, or any other non-residential property in the UK, one of the most significant upfront costs you need to plan for is Stamp Duty Land Tax (SDLT). Yes — there is stamp duty on commercial property, and understanding how it works could save you thousands of pounds on your transaction.
This guide covers everything business owners, investors, landlords, and property professionals need to know about stamp duty on commercial property: the current rates, how the tax is calculated, what reliefs are available, and how commercial SDLT compares to residential stamp duty.
| Quick Answer: Is There Stamp Duty on Commercial Property?
Yes. Stamp Duty Land Tax (SDLT) applies to all non-residential and mixed-use property purchases in England and Northern Ireland where the purchase price is £150,000 or more. The rates are 0%, 2%, and 5%, applied progressively on each slice of the price. Crucially, commercial SDLT has a higher nil-rate threshold (£150,000) and a much lower top rate (5%) than residential SDLT (top rate 12%), making it a more tax-efficient option in many scenarios. |

What Is Stamp Duty Land Tax (SDLT)?
Stamp Duty Land Tax is a UK government tax charged on the purchase of land and property in England and Northern Ireland. It replaced the old stamp duty system in December 2003 and is administered by HM Revenue and Customs (HMRC). In Scotland, an equivalent tax called Land and Buildings Transaction Tax (LBTT) applies, while in Wales it is known as Land Transaction Tax (LTT).
SDLT is a self-assessed tax. The buyer — not the seller — is responsible for submitting an SDLT return to HMRC and paying any tax due. In practice, your solicitor or conveyancer will usually handle this on your behalf as part of the conveyancing process.
Key point: You must file an SDLT return and pay any tax owed within 14 days of the completion date. Late filing can result in HMRC penalties and interest charges.
What Counts as Commercial Property for SDLT Purposes?
HMRC defines non-residential (commercial) property broadly. For SDLT purposes, the following types of property attract commercial rates:
- Shops, retail units, and restaurants
- Offices and serviced office space
- Warehouses, industrial units, and factories
- Agricultural land and farmland
- Forests and woodland
- Land and buildings that are not suitable for residential use
- Six or more residential dwellings purchased in a single transaction (treated as a commercial transaction)
- Mixed-use properties — buildings with both a residential and commercial element, such as a flat above a shop or a pub with living accommodation
Mixed-use properties are particularly important for SDLT planning because they attract the lower commercial rates rather than the higher residential rates. This can represent a significant saving, especially on higher-value properties.
Stamp Duty on Commercial Property: Current Rates (2025/26)
The current SDLT rates for non-residential and mixed-use property in England and Northern Ireland (applicable from April 2025) are as follows:
| Purchase Price Band | SDLT Rate | SDLT Payable (on slice) |
|---|---|---|
| Up to £150,000 | 0% | £0 |
| £150,001 – £250,000 | 2% | Up to £2,000 |
| Above £250,000 | 5% | 5% on the excess |
| Worked Example: Buying a Commercial Property for £375,000
0% on the first £150,000 = £02% on the next £100,000 (£150,001 to £250,000) = £2,0005% on the remaining £125,000 (above £250,000) = £6,250Total SDLT = £8,250For comparison, if this were a standard residential purchase, the SDLT would be approximately £11,250 — and with the additional dwelling surcharge, it could reach £30,000 or more. |
Commercial SDLT vs Residential SDLT: Key Differences
One of the most frequently misunderstood aspects of stamp duty is how significantly the commercial and residential regimes differ. Here is a side-by-side comparison:
| Feature | Commercial SDLT | Residential SDLT |
|---|---|---|
| Nil-rate threshold | £150,000 | £125,000 (from Apr 2025) |
| Top rate | 5% | 12% |
| Additional dwelling surcharge | Not applicable | 5% surcharge applies |
| Non-resident surcharge | Not applicable | 2% surcharge applies |
| Mixed-use property | Commercial rates apply | Residential rates apply |
| New leasehold (rent element) | 1%/2% on NPV | 1% on NPV over £125,000 |
The most striking difference is the top rate: commercial SDLT is capped at 5%, whereas residential SDLT can reach 12% — and up to 17% for certain non-natural persons (e.g. companies) purchasing high-value residential property. This makes commercial and mixed-use property considerably more attractive from an SDLT perspective, particularly for corporate buyers and overseas investors.
SDLT on Commercial Leases: How It Works
When you take on a new commercial lease rather than purchasing a freehold property, SDLT may still be payable — but the calculation is different. SDLT on commercial leases applies to two separate elements:
1. The Lease Premium
If you pay an upfront sum (premium) to take on the lease, SDLT is charged using the same 0%/2%/5% rate bands as for a freehold purchase.
2. The Net Present Value (NPV) of Rent
SDLT is also payable on the total rental value of the lease over its term, expressed as a net present value (NPV). The NPV is the current value of all future rent payments, discounted using HMRC’s prescribed rate.
- 0% on the NPV of rent up to £150,000
- 1% on the NPV of rent between £150,001 and £5,000,000
- 2% on the NPV of rent above £5,000,000
Both the premium element and the rent element are calculated separately, and the resulting SDLT amounts are added together. HMRC’s SDLT calculator can assist with these calculations for complex lease structures.
SDLT Reliefs and Exemptions on Commercial Property
Several SDLT reliefs exist that can reduce or eliminate the tax due on a commercial property transaction. Key reliefs to be aware of include:
Multiple Dwellings Relief (MDR) — Now Abolished
Multiple Dwellings Relief was abolished for transactions completing on or after 1 June 2024. Prior to that date, it could reduce SDLT where six or more residential properties were purchased in a single transaction. Today, such purchases are simply taxed at commercial rates — which can still be beneficial.
Charities Relief
Registered charities can claim SDLT relief when purchasing property that will be used for charitable purposes. The relief reduces SDLT to nil, subject to conditions.
Group Relief
Where a company acquires property from another company within the same corporate group, SDLT group relief may apply to reduce or eliminate the tax charge. This is a common planning tool for corporate restructuring.
Sale and Leaseback Relief
Certain sale and leaseback transactions may attract SDLT relief, reducing the overall tax cost for businesses restructuring their property portfolios.
Zero Carbon Commercial Buildings
Commercial buildings that meet specific energy efficiency criteria may qualify for SDLT relief, although the rules are narrow and legal advice is recommended.
VAT and Stamp Duty on Commercial Property
One issue that catches many commercial property buyers by surprise is the interaction between VAT and SDLT. Commercial property is ordinarily exempt from VAT. However, a seller can elect to waive this exemption — known as opting to tax — which makes the sale subject to 20% VAT.
If VAT is charged on the purchase price, SDLT is calculated on the VAT-inclusive amount. This means a £500,000 commercial property subject to VAT at 20% would have a total consideration of £600,000 for SDLT purposes — significantly increasing your stamp duty bill.
Planning tip: If you are VAT-registered and buying a commercial property subject to VAT, you can generally recover the VAT through your VAT return — but the SDLT uplift is not recoverable. Identifying the VAT position early is essential.
How to File and Pay SDLT on a Commercial Property
Paying stamp duty on a commercial property follows a straightforward process, typically managed by your solicitor:
- Your solicitor completes the SDLT1 land transaction return on your behalf.
- The return and payment must be submitted to HMRC within 14 days of the completion date.
- HMRC issues an SDLT5 certificate confirming the return has been processed.
- The SDLT5 is required by the Land Registry to register the property transfer.
HMRC offers an online SDLT calculator at gov.uk/stamp-duty-land-tax to provide an estimate of the tax due, although this should always be verified by a qualified accountant or solicitor before exchange of contracts.
Common Mistakes to Avoid When Paying SDLT on Commercial Property
Errors on SDLT returns can be costly. The most common mistakes seen in commercial property transactions include:
- Misclassifying a mixed-use property as purely residential, resulting in excess SDLT
- Failing to account for VAT in the chargeable consideration where the seller has opted to tax
- Incorrectly claiming SDLT reliefs without meeting all qualifying conditions
- Missing the 14-day filing deadline, triggering late filing penalties
- Failing to file an SDLT return at all on sub-threshold transactions (a return is still required on most transactions below £150,000)
- Not obtaining professional advice on linked transactions, which can aggregate purchase prices and push the effective SDLT rate higher

Frequently Asked Questions: Stamp Duty on Commercial Property
Do you pay stamp duty on commercial property in the UK?
Yes. In England and Northern Ireland, stamp duty on commercial property is charged as Stamp Duty Land Tax (SDLT). The tax applies when you purchase non-residential or mixed-use property with a value of £150,000 or more. In Scotland, the equivalent tax is Land and Buildings Transaction Tax (LBTT), and in Wales it is Land Transaction Tax (LTT).
What are the current stamp duty rates for commercial property?
The current SDLT rates for commercial property (2025/26) are: 0% on the first £150,000; 2% on the portion between £150,001 and £250,000; and 5% on the portion above £250,000. These are applied progressively, so only the relevant slice of the purchase price attracts each rate.
Is stamp duty on commercial property the same as residential?
No. Commercial SDLT rates are generally much lower than residential rates. The commercial nil-rate threshold is higher (£150,000 versus £125,000 for residential from April 2025), and the top rate is only 5% compared to 12% for residential property. Commercial purchases are also exempt from the additional dwelling surcharge (5%) and non-resident surcharge (2%) that can significantly increase residential SDLT bills.
Do you pay stamp duty on a commercial lease?
Yes, in many cases. When entering a new commercial lease, SDLT may be payable on the lease premium (upfront sum) using the standard commercial rate bands, and also on the net present value (NPV) of the rent over the lease term. The rental element is taxed at 1% on the portion of the NPV between £150,001 and £5,000,000, and 2% above that.
Is a flat above a shop charged residential or commercial stamp duty?
A flat above a shop is a mixed-use property and is taxed at commercial SDLT rates, not residential rates. This can result in significant savings compared to paying standard or higher-rate residential SDLT, particularly on properties valued above £250,000.
Can you claim SDLT relief on a commercial property purchase?
Yes, various SDLT reliefs are available, including charities relief, group relief, and sale and leaseback relief. However, reliefs are subject to specific conditions and can be challenged by HMRC if incorrectly claimed. Professional advice from a qualified accountant is strongly recommended before claiming any relief.
Does VAT affect stamp duty on commercial property?
Yes. If the seller has opted to tax the commercial property (making the sale subject to 20% VAT), SDLT is calculated on the VAT-inclusive purchase price. This can significantly increase your SDLT liability. VAT-registered buyers can usually reclaim the VAT, but the additional SDLT cost is not recoverable.
When must stamp duty on a commercial property be paid?
You must file an SDLT return and pay any SDLT due within 14 days of the completion date of the property purchase. Failure to meet this deadline can result in HMRC penalty notices and interest charges. Your solicitor will typically manage this process as part of the conveyancing.
