How to Calculate Stamp Duty for a Limited Company: Breaking Down the Basics
Let’s Start with the Straight Answer
Now, if you're running a limited company in the UK and thinking of buying a residential or commercial property, here’s the deal: you do pay Stamp Duty Land Tax (SDLT) — and in most cases, you’ll pay more than an individual would.
Why? Because companies often trigger higher rate thresholds, additional surcharges, or fall into specific tax brackets that HMRC has reserved just for non-natural persons (yes, that includes your registered business).
Let’s unpack it.
What Is Stamp Duty Land Tax (SDLT) for Limited Companies?
None of us is a tax expert by birth, so here’s the plain English: SDLT is a land transaction tax — a lump-sum payment due when you buy a freehold, leasehold, or even take on a mortgage in exchange for property. Limited companies, just like individuals, are liable to pay SDLT — but often at enhanced rates, especially for residential properties.
Now, it shouldn’t be a surprise for you to learn that the rates vary depending on:
Whether it’s a residential or non-residential property,
If the price exceeds certain thresholds,
Whether the property is located in England or Northern Ireland (Scotland and Wales have different systems), and
If the company qualifies for any relief or exemption.
Be Careful! These Are the SDLT Rates for Companies in 2025
So, the question is — what will your company really pay?
Here’s the latest SDLT rate chart applicable to limited companies buying residential properties as of May 2025:
Table 1: SDLT Residential Rates for Limited Companies (2025)
✅ Important Notes:
3% surcharge applies to all additional properties.
2% surcharge applies if the company is considered non-resident.
In some cases, 15% flat rate applies to residential properties over £500,000, particularly if the company is not using the property for letting or commercial purposes.

But What If It’s Commercial Property or Land?
Now consider this: If your company is buying an office block, warehouse, or a patch of land for future development, then it’s non-residential — and the rates are much lower (and simpler).
Table 2: SDLT Non-Residential Rates for Limited Companies
✅ Tip: No 3% or 2% surcharges apply to non-residential property.
Alright, But How Do You Actually Calculate It?
Here’s where most people mess it up. SDLT is calculated in bands — much like income tax. So you don’t pay 5% on the whole price if your property is £300,000. You pay:
0% on the first £250,000,
5% on the next £50,000,
Plus surcharges if applicable.
Example:
Say your company buys a flat in London for £800,000.
Assuming:
It’s a residential property,
The company is UK-based, but already owns another property,
It doesn’t qualify for any relief.
Your SDLT bill will be:
That’s before any other surcharge or relief is applied.
Step-by-Step Guide: Calculating SDLT for a Limited Company (Residential)
Now if you’re still not sure how to go about it, here’s your DIY kit:
Step 1: Identify Property Type
Is it residential or non-residential?
Mixed-use counts as non-residential.
Step 2: Work Out the ‘Consideration’
This is the purchase price plus any debt transferred, services, or benefits exchanged.
Outstanding mortgage counts.
Step 3: Apply SDLT Rates Band-by-Band
Use the band system to calculate tax for each threshold.
Step 4: Add Surcharges
+3% for any additional residential property.
+2% if company is non-UK resident.
Flat 15% rate may apply if it’s residential property over £500,000 not used for commercial purposes.
Step 5: File the Return
SDLT return must be filed within 14 days of completion.
Usually done by your solicitor, but you can file it yourself if needed.

Real-World Case Study: Rajpal Holdings Ltd
Let’s say Rajpal Holdings Ltd (based in Manchester) bought a buy-to-let property in Leeds worth £950,000 in April 2025.
Facts:
Already owns 2 other properties.
Residential purpose (letting).
Company is UK-resident.
SDLT Breakdown:
No 15% flat rate because the property is for letting, not for personal use.
Common Mistakes to Avoid
Be careful! These are classic blunders companies make:
Assuming residential rates apply flatly across the full price.
Ignoring the 3% surcharge thinking it only applies to individuals.
Forgetting about debt transfers which can trigger SDLT even on "free" transfers.
Not checking reliefs, especially for development companies or REITs.
Missing the 14-day filing deadline, which leads to automatic penalties.
Advanced SDLT Strategies for Limited Companies: Exemptions, Transfers, and Practical Realities
Now Consider This: You Transfer Property to Your Own Company...
So the question is — what happens if you already own a residential property personally, and now want to move it under your limited company’s name? Pretty common, especially for landlords looking to ringfence assets or gain tax efficiencies.
Be careful! HMRC doesn’t see this as an “internal reshuffle.” It sees it as a chargeable land transaction — just like any sale. Even if no money changes hands, the company has still “acquired” property, and that’s enough to trigger SDLT.
Here’s the kicker:
SDLT is based on the property's market value, not what you paid for it originally.
If there’s a mortgage involved, the debt taken on by the company is also considered “consideration” for SDLT purposes.
👉 Example: If you transfer a buy-to-let flat worth £450,000 (with a £300,000 mortgage) to your company, SDLT is payable on the full £450,000, even if no cash changed hands.
So, Are There Any Reliefs to Help You Out?
None of us is thrilled about paying more tax than we need to. Luckily, there are a few reliefs out there — but don’t assume you qualify unless you meet all the conditions.
1. Partnership Incorporation Relief
This one's a bit of a unicorn. If your business qualifies as a genuine partnership (typically involving more than one individual actively participating), and you're transferring properties to a newly formed company, SDLT relief may apply under FA2003, Sch 15.
✅ Criteria include:
The partnership has to be real, not artificial.
The property must have been used in the business.
The transfer must be in exchange for company shares, not cash.
⚠️ Tip: If it’s just you running a sole trader BTL business, this relief won’t fly. HMRC won’t consider that a partnership.
2. Group Relief
Applicable when the transfer is between companies within the same group. It’s a popular strategy for large real estate holding structures, where property is shuffled between subsidiaries.
✅ Criteria:
Both companies must be 75% owned by a common parent.
The transaction must not be part of a scheme to avoid tax.
⚠️ Trap: If the group dissolves or a company exits within 3 years, the relief can be clawed back.
3. Property Used for Qualifying Trade
If the company plans to use the property in a genuine business activity, such as letting or development, it may be exempt from the punitive 15% flat SDLT rate that applies to high-value residential purchases.
✅ This applies only if:
The property is let commercially to third parties.
It’s not occupied by a company director, their family, or friends.
The business has evidence of trading (e.g., rental agreements, development plans).
Real Case Study: Hawkins & Mead Ltd
In July 2024, Hawkins & Mead Ltd — a Brighton-based SME — transferred two properties from a family-owned partnership to a new limited company. Each property was worth around £600,000, with active tenants and long-standing lease agreements.
The company applied for Partnership Incorporation Relief and submitted SDLT returns with claim annotations.
✅ Outcome:
HMRC approved the relief after requesting partnership profit & loss accounts and historic tenancy records.
No SDLT was payable, saving the company nearly £78,000.
When the 15% Flat Rate Kicks In — and When It Doesn’t
Now it shouldn't be a surprise for you to hear about the infamous 15% flat SDLT rate. Introduced to combat tax avoidance through company property ownership, it applies when:
A corporate body (like a limited company) buys a residential property over £500,000, and
The property is not let or used for qualifying commercial purposes.
This is called the “enveloped dwellings” rule, and it’s brutal.
When You’ll Pay 15% Flat Rate SDLT:
🚨 Warning: The Annual Tax on Enveloped Dwellings (ATED) may also apply if the company holds residential property worth over £500,000. ATED is a yearly tax, separate from SDLT, ranging from £4,400 to £287,500 depending on property value.

Transfer of Mortgaged Properties – The Often-Ignored Trap
Now imagine this: You bought a flat 10 years ago for £200,000, with a mortgage of £180,000. Today it’s worth £600,000, and you want to transfer it to your company.
What most people miss is that SDLT is charged on the market value, not what’s outstanding on the mortgage. So yes, even if it’s “your” company, and no money changes hands, HMRC still wants its SDLT based on £600,000.
SDLT Calculation Example:
Market value: £600,000
Residential band: triggers 5% + 3% = 8%
SDLT: 8% of £600,000 = £48,000
There’s no “mate’s rates” discount just because it’s your company. It’s the open market value that matters.
Common Questions Business Owners Ask
None of us likes surprises from HMRC. Here are the “people also ask” questions that we’ll tackle here for good measure:
“Do I pay SDLT if I transfer a property to my company for free?”
Yes. If the company assumes any mortgage or debt, or receives the property as part of an arrangement, SDLT is triggered on the market value or debt assumed — whichever is higher.
“Can I reclaim SDLT if I later sell the property at a loss?”
No. SDLT is a transaction tax, not based on investment outcome. Selling at a loss won’t give you a refund.
“What if I buy multiple properties at once?”
You may qualify for Multiple Dwellings Relief (MDR) — which lets you apply SDLT to the average price per unit, rather than the total. Can be a big saver if buying 4–5 flats at once.
“What if my company is based overseas?”
You’ll face an extra 2% SDLT surcharge for non-UK residents. That’s in addition to the usual 3% surcharge for residential purchases.
Practical Tips to Reduce Your SDLT Bill — Legally
Alright, let’s talk tactics. Here’s how UK companies legally reduce their SDLT liability:
Purchase commercial properties or mixed-use buildings (lower rates, fewer surcharges).
Structure as a partnership first, then incorporate — if legitimate.
Keep records of rental activity to qualify for reliefs.
Time your transactions wisely — e.g., around tax-year transitions.
Use specialist solicitors who understand SDLT law — seriously, it’s worth the fee
Top 10 Must-Know Insights on Calculating Stamp Duty for Limited Companies : Quickfire Summary
Now if you’ve stuck with this guide so far, hats off — you’re already ahead of most UK business owners. But just in case you want a fast refresher or a shareable checklist, here are the 10 most important takeaways — plain, punchy, and built to save you from costly SDLT mistakes.
1. Companies pay higher SDLT rates on residential properties
If your limited company buys residential property, expect the standard SDLT, plus a 3% surcharge, and potentially a 15% flat rate for properties over £500,000 not used commercially.
2. Non-resident companies face an additional 2% SDLT surcharge
Even if your company is based overseas but buys UK property, you’re slapped with an extra 2% on top of everything else — which can push the SDLT up to 17% in some cases.
3. SDLT is calculated in bands — not as a flat percentage
So don’t fall into the trap of applying one rate across the entire purchase price. SDLT works progressively, like income tax — each slice of the price is taxed at a different rate.
4. SDLT applies even when transferring property to your own company
Thinking of moving a property you personally own into your business? If there’s a mortgage or market value involved, HMRC sees that as a chargeable transaction — and SDLT applies.
5. The 15% flat rate applies to residential property over £500k for non-commercial use
If the company buys a £700,000 house and nobody’s letting it or trading from it — bang, 15% SDLT hits you. Unless it’s a commercial use case, there’s no relief.
6. Partnership incorporation can avoid SDLT — but only in genuine setups
If two or more people run a legit business partnership and form a limited company, they might qualify for SDLT relief, but this doesn't apply to sole traders transferring property.
7. Non-residential and commercial properties are taxed more lightly
Limited companies buying offices, warehouses or land face lower SDLT rates (0%, 2%, 5%) — and no surcharges or 15% surprises. That’s why commercial property is often a tax-smart choice.
8. Transferring a mortgaged property counts as “consideration”
If the company takes on your mortgage — even if no cash changes hands — that’s enough to trigger SDLT. The tax is based on the higher of the debt or the property’s market value.
9. You’ve only got 14 days to file and pay SDLT
Whether it’s you or your solicitor, HMRC expects SDLT to be filed and paid within 14 days of completion — miss that, and the penalties start adding up fast.
10. Use reliefs like Group Relief, MDR or commercial use exemptions to cut SDLT
There are genuine reliefs available for companies — like group restructuring, Multiple Dwellings Relief (MDR), or using property for commercial purposes. Know them. Use them.
Stamp Duty Calculator For a Limited Company
FAQs
Q1. Does a limited company pay SDLT on a property gifted to it by a director?
Yes, a limited company must still pay Stamp Duty Land Tax (SDLT) on the market value of a gifted property, especially if the company takes on an existing mortgage. It is considered a chargeable transaction regardless of money changing hands.
Q2. Can a limited company avoid SDLT by buying property in Scotland or Wales?
No, limited companies cannot avoid land transaction taxes. In Scotland, they pay LBTT (Land and Buildings Transaction Tax) and in Wales, LTT (Land Transaction Tax), both of which have rules and rates similar to SDLT in England and Northern Ireland.
Q3. Is SDLT different if the company is buying a leasehold property instead of a freehold?
The SDLT rules still apply to leasehold purchases, but the calculation may include the net present value of rent due under the lease in addition to the premium paid. This can affect the total SDLT liability.
Q4. Can a limited company claim back SDLT after a property deal falls through?
If the transaction is rescinded before completion, no SDLT is due. But if completion occurred and then the deal is reversed, the company usually cannot reclaim SDLT unless a refund is allowed under specific relief criteria, such as overpayment.
Q5. Is there a difference in SDLT for a limited company buying multiple properties in one deal?
Yes, the company may qualify for Multiple Dwellings Relief (MDR), which can reduce the SDLT bill by applying tax to the average price of each dwelling rather than the total sum.
Q6. Can you offset SDLT as a business expense in corporation tax?
No, SDLT cannot be deducted as an allowable business expense against trading profits for corporation tax. However, it may be included as part of the capital cost of the property for future capital gains calculations.
Q7. What happens if a company buys a mixed-use property—does residential SDLT still apply?
No, if any part of the property is used for non-residential purposes (like a shop with a flat above), it is classed as mixed-use and SDLT is charged at the lower commercial property rates.
Q8. Does SDLT apply to properties bought through a Special Purpose Vehicle (SPV)?
Yes, SDLT applies to properties purchased by SPVs in the same way as other limited companies. SPVs do not receive any unique exemptions or reliefs from SDLT.
Q9. Can a limited company defer paying SDLT?
No, SDLT must be paid within 14 days of the completion of the transaction. There is no official mechanism for deferring SDLT payment, and penalties apply for late filing or payment.
Q10. Is SDLT due if a company receives property through inheritance?
No, SDLT is not payable on inherited property because it is not considered a chargeable land transaction. However, future transfers of inherited property may be subject to SDLT.
Q11. Can a company use rollover relief to reduce SDLT on property purchases?
No, rollover relief is not available for SDLT. It is a capital gains tax relief and does not apply to land transactions or property acquisitions by companies.
Q12. Does transferring property from a dissolved company to a shareholder attract SDLT?
Yes, if a property is distributed from a dissolved company to a shareholder, SDLT is usually due based on the market value of the property at the time of transfer.
Q13. Are there SDLT exemptions for charities operating through limited companies?
Only if the charity is a registered charitable company and the property is used for charitable purposes. Normal trading limited companies do not qualify for charity-based SDLT exemptions.
Q14. Can a dormant company purchase property without paying SDLT?
No, SDLT liability depends on the transaction, not the trading status. Dormant companies are still subject to SDLT if they acquire property above the threshold.
Q15. Is SDLT applicable when a company acquires property via a share purchase of another company?
No SDLT is charged directly in this case, but the company buying shares must consider indirect property ownership taxes. However, this approach may trigger other tax implications like ATED or corporation tax issues.
Q16. Does HMRC offer SDLT payment plans for limited companies?
No, HMRC does not offer installment plans for SDLT. The full amount must be paid within 14 days of completion, or penalties and interest will apply.
Q17. Can a limited company reclaim overpaid SDLT if it qualified for relief but didn’t apply?
Yes, a company can amend the SDLT return and apply for a refund within 12 months of the filing date if it mistakenly didn’t claim eligible relief.
Q18. Are there SDLT implications if a director occupies a company-owned residential property?
Yes, the 15% flat SDLT rate may apply, and the property may also fall under the Annual Tax on Enveloped Dwellings (ATED), especially if valued over £500,000.
Q19. What happens if a company buys property jointly with an individual—how is SDLT assessed?
In such joint purchases, SDLT is usually calculated based on the entire transaction value, and corporate surcharges may still apply, even if the individual is a co-owner.
Q20. Can a company transfer a property to a pension scheme without SDLT?
Only if it qualifies under specific pension fund exemptions, like transfers to a registered pension scheme in exchange for pension benefits. Most transfers are still subject to SDLT unless fully exempt under pension rules.
