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 on 1 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).
Stamp duty on commercial property 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 usually handles this on your behalf as part of the conveyancing process.
Important: You must submit an SDLT return and pay any tax due within 14 days of the effective date of the transaction. This is usually the completion date. However, it can be earlier in certain circumstances. Late filing or payment may result in penalties and interest.
Do You Pay Stamp Duty on Commercial Property UK?
Yes, you pay stamp duty on commercial property when you purchase non-residential property and land in England and Northern Ireland. Under the current non-residential SDLT rates in the UK, the purchase price is charged in stages, as mentioned in the table below.
These SDLT rules can apply whether you are buying through a sole trader, limited company, or partnership. Also, SDLT can apply to certain lease transactions, with the tax treatment depending on the premium and rent involved.
What Counts as Commercial Property for SDLT Purposes?
For SDLT purposes, non-residential property includes land and property that is not residential property. Here are some examples:
- Shops, restaurants, retail units
- Offices and serviced office space
- Warehouses, factories, and industrial units
- 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, such as buildings with both a residential and commercial element
Generally, stamp duty on commercial property applies to mixed-use transactions through the non-residential SDLT rates. The SDLT payable will depend on the purchase price and the specific circumstances of the transaction.
What Doesn’t Count as Commercial Property?
Typically, residential property does not count as commercial property for stamp duty on commercial property purposes. This includes:
- A home you live in
- Residential properties purchased as buy-to-let investments, provided they meet the SDLT definition of residential property.
Additionally, these transactions are subject to the residential SDLT rules rather than the non-residential rates.
However, a mixed property, containing both residential and non-residential elements, such as a shop with a flat above it, is usually treated as mixed-use. Such properties are subject to the non-residential SDLT rates.
What Are the Current Stamp Duty Rates on Commercial Property?
The current rates of stamp duty on commercial property and mixed-use property in England and Northern Ireland are outlined below in the table:
| Purchase Price Band | SDLT rate |
| Up to £150,000 | 0% |
| £150,001–£250,000 | 2% |
| Above £250,000 | 5% |
These rates apply to increasing portions, or slices, of the purchase price rather than the entire property price.
Example: Buying a Commercial Property for £375,000
Let’s say you are buying a commercial property for £375,000:
- 0% on the first £150,000 = £0
- 2% on the next £100,000 = £2,000
- 5% on the remaining £125,000 = £6,250
Total SDLT = £8,250
For comparison, a £375,000 residential property bought as a single residential property would have SDLT of £12,500 under the current standard residential rates, before considering any applicable reliefs or higher rates.
Commercial SDLT vs Residential SDLT: Key Differences
Rates of stamp duty on commercial property and residential property are different in England and Northern Ireland. The main differences are highlighted in the table below:
| Feature | Commercial / Non-Residential SDLT | Residential SDLT |
| Nil-rate threshold | £150,000 | £125,000 under standard residential rates |
| Main top rate | 5% | £125,000 under standard residential rates |
| Additional dwelling rates | Not applicable | Higher rates can apply to additional properties |
| Non-UK resident surcharge | Not applicable to non-residential property | 2% surcharge can apply to certain purchases |
| Mixed-use property | Non-residential rates generally apply | Not treated solely as residential |
| New leasehold rent element | 0%, 1% or 2% depending on the rent’s NPV | 1% on the portion above the residential NPV threshold |
For a new non-residential lease, stamp duty on commercial property can apply separately to the lease premium and the net present value (NPV) of the rent. For the rent element, the current rates are 0% up to £150,000, 1% on the portion from £150,001 to £5 million and 2% on the portion above £5 million.
Additionally, mixed-use transactions are subject to the non-residential SDLT rates. The rules can vary for certain residential purchases, including purchases by companies and other non-natural persons.
Do You Pay Stamp Duty on Commercial Property Lease
Yes, SDLT can apply when you take a new commercial lease. 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:
-
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.
-
The Net Present Value (NPV) of Rent
SDLT can also be payable on the NPV of the rent payable over the lease term. The NPV is calculated using the statutory method prescribed for SDLT purposes.
- 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. A stamp duty on commercial property calculator can help to estimate how much you need to pay.

SDLT Reliefs and Exemptions on Commercial Property
Several SDLT reliefs exist that can reduce or eliminate the stamp duty on commercial property transactions. 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.
Does VAT Affect Stamp Duty on Commercial Property?
Yes, Value Added Tax (VAT) can affect the amount on which SDLT is calculated. One issue that can catch 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 commercial property follows a simple process, typically managed by your solicitor:
- Your solicitor completes the SDLT1 land transaction return on your behalf.
- The SDLT return and any tax due must be submitted and paid within 14 days of the effective date of the transaction.
- HMRC issues an SDLT5 as evidence to confirm the return has been submitted. The SDLT5 is required by the Land Registry to register the property transfer.
- Then, your solicitor can complete the relevant property registration process with HM Land Registry.
What Are the Common Mistakes to Avoid When Paying Stamp Duty 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.
Key Takeaways: Stamp Duty on Commercial Property
- Yes, there is stamp duty on commercial property in England and Northern Ireland; it is called Stamp Duty Land Tax (SDLT).
- Commercial SDLT applies to non-residential and mixed-use property at rates of 0%, 2%, and 5%, with a nil-rate threshold of £150,000.
- Commercial SDLT does not attract the additional dwelling surcharge (5%) or the non-resident surcharge (2%) that apply to residential purchases.
- Mixed-use properties, such as a flat above a shop, are taxed at commercial SDLT rates.
- On a commercial lease, SDLT may be payable on both the lease premium and the net present value of the rent.
- VAT can inflate the SDLT base cost if the seller has opted to tax the property.
- SDLT returns and any tax due must generally be submitted and paid within 14 days of the effective date of the transaction.
Is Stamp Duty on Commercial Property the Same as Residential?
No, commercial SDLT rates are calculated differently than residential rates. The current rates for non-residential property are 0% up to £150,000, 2% on the portion from £150,001 to £250,000 and 5% on the portion above £250,000.
However, residential property has different rates and thresholds. The highest standard non-residential SDLT rate is 5%, whereas residential SDLT rates vary depending on the purchase and the buyer’s circumstances.
Moreover, Higher rates can apply to certain additional residential properties, and a 2% non-UK resident surcharge can apply to certain residential purchases. Commercial and non-residential property transactions are not subject to these residential surcharges.
When Do You Need to Pay Stamp Duty on Commercial Property?
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. Note that your solicitor will typically manage this process as part of the conveyancing.
Is a Flat Above a Shop Charged Residential or Commercial Stamp Duty?
A flat above a shop is a mixed-use property. It is taxed at commercial SDLT rates, not residential rates. Therefore, this can result in significant savings compared to paying standard or higher-rate residential SDLT, particularly on properties valued above £250,000.
