The Limited Company Stamp Duty Calculator estimates Stamp Duty Land Tax (SDLT) for supported company property purchases in England and Northern Ireland. Use it to check the company residential bands, the flat corporate charge above £500,000 and the effect of a confirmed non-resident surcharge. It also supports straightforward wholly non-residential purchases and provides a transparent breakdown of your estimate.

• Accepts VAT-inclusive prices, an added 20% VAT amount or separately confirmed VAT.
• Shows the amount in each tax band and the effective tax rate.
• Compares up to three transaction snapshots while the page remains open.
• Adds quoted buying costs to a gross acquisition budget.
• Provides an indicative filing deadline, a downloadable report and Print / PDF options.

How Much Stamp Duty Does a Limited Company Pay?

For a supported single-dwelling purchase of at least £40,000, a company normally uses the higher residential bands. Above £500,000, a flat corporate charge may replace that calculation unless qualifying relief applies. An applicable non-resident surcharge can increase either calculation. The table below shows the banded calculation used in this tool from 1 April 2025. It does not apply where the flat corporate charge is due.

Banded company residential SDLT rates

Portion of chargeable price	Company bands	With applicable non-resident surcharge
Up to £125,000	5%	7%
Over £125,000 to £250,000	7%	9%
Over £250,000 to £925,000	10%	12%
Over £925,000 to £1,500,000	15%	17%
Over £1,500,000	17%	19%

Each rate applies only to the portion within its band. The company uplift is already included. See HMRC’s higher-rate guidance and its company purchase rules.

When Does the 17% Corporate Stamp Duty Rate Apply?

The flat 17% corporate charge can apply to a company’s acquisition of a dwelling for more than £500,000 where no relevant relief applies. It is charged on the full consideration, rather than only the amount above the threshold. The flat charge replaces the banded company calculation: do not add another 5% to it. If the 2% non-resident surcharge applies, the combined flat rate is 19%. Exactly £500,000 does not exceed this threshold. The calculator uses the full chargeable amount, including payable VAT, when checking the threshold. Read HMRC’s corporate-bodies guidance.

Does a Buy-to-Let Company Automatically Qualify for Relief?

No. A company name, SPV structure or intention to let property does not by itself establish relief. A qualifying rental business must satisfy the applicable conditions. Other qualifying uses can also fall within specific relief provisions. Where qualifying rental-business relief removes the flat charge, the higher residential bands still apply. The calculator asks you to confirm the relief position; it does not assess eligibility. See HMRC’s rental-business relief guidance.

Can Relief Be Withdrawn Later?

Yes. Changes during the relevant three-year control period can cause relief to be withdrawn. The detailed conditions and exceptions depend on the relief. The calculator does not monitor later occupation or business use, or calculate a clawback. Review HMRC’s withdrawal-of-relief guidance before relying on a claim.

Worked Example: A £300,000 Company Property Purchase

For a supported residential purchase with £300,000 chargeable consideration and no non-resident surcharge, estimated SDLT is £20,000.

• £125,000 at 5%: £6,250.
• £125,000 at 7%: £8,750.
• £50,000 at 10%: £5,000.
• Total: £20,000.

The effective tax rate is approximately 6.67%. Adding the confirmed non-resident surcharge would increase this example’s total to £26,000.

Worked Example: A £600,000 Company Purchase

The relief decision makes a substantial difference to a supported £600,000 residential purchase:

Conditional SDLT estimates for £600,000 chargeable consideration

Confirmed treatment	Without non-resident surcharge	With non-resident surcharge
Qualifying corporate relief; company bands apply	£50,000	£62,000
No corporate relief; flat charge applies	£102,000	£114,000

These are conditional examples, not tax options you can freely choose. Your transaction must meet the legal conditions for the treatment used. The calculator shows both illustrations above £500,000 to make the importance of that assessment visible.

How Does the Non-Resident Surcharge Work for Companies?

The residential non-resident surcharge adds two percentage points to the relevant rates. Corporate residence tests differ from an individual’s day-count test. Certain UK-resident close companies under non-UK control can also fall within the surcharge rules. Do not select “No” just because the company is registered in the UK. Confirm the company’s position under the official non-resident guidance, including the close-company control rules. The tool accepts the confirmed outcome rather than attempting to classify a corporate ownership structure.

How to Use the Limited Company Stamp Duty Calculator

1. Select the location. England and Northern Ireland use this SDLT engine; Wales and Scotland are directed to their official tax services.
2. Choose the property classification. Select one residential dwelling or wholly non-residential property.
3. Select the interest being bought. Choose freehold or a supported existing-lease assignment and confirm any lease conditions shown.
4. Confirm the transaction scope. Check that no excluded specialist features apply.
5. Enter the full chargeable price. Do not enter only the deposit or mortgage balance.
6. Confirm VAT treatment. Avoid adding VAT twice to a price that already includes it.
7. Confirm the residential tax treatment. State whether the non-resident surcharge applies and, above £500,000, whether qualifying corporate relief applies.
8. Add optional costs and the effective date. These provide a budget subtotal and indicative filing deadline.
9. Calculate and inspect the result. Review the treatment, bands and assumptions before comparing or downloading it.

Can a Company Calculate Stamp Duty on Commercial Property?

Yes. This calculator supports straightforward wholly non-residential company purchases. It uses 0% on the first £150,000, 2% on the next £100,000 and 5% above £250,000, without the residential company uplift or residential non-resident surcharge. Mixed-use transactions are excluded because allocating and classifying residential elements can require a separate assessment. See HMRC’s non-residential rates.

Does the Purchase Price Include VAT?

Any VAT payable on the transaction forms part of the chargeable consideration. Expected VAT recovery does not remove it from the SDLT base. The tool lets you enter an inclusive price, add 20% where applicable, or specify a confirmed VAT figure. Do not assume VAT applies to every property. Confirm its treatment separately, including any option-to-tax, exemption or transfer-of-a-going-concern issues. See HMRC’s consideration guidance.

Understanding Your Company SDLT Result

• Applicable treatment: identifies the company bands, flat corporate charge or non-residential calculation used.
• Estimated SDLT: the tax calculated from your supported inputs.
• Effective rate: estimated SDLT divided by the chargeable amount.
• Tax-band breakdown: shows the amount assessed at each applicable rate.
• Gross acquisition budget: price, VAT added, estimated SDLT and other quoted costs entered.
• Conditional relief illustrations: show how the residential result above £500,000 changes if relief applies or does not apply.

The budget is before financing or VAT recovery. It excludes unentered costs, ongoing rent and other taxes such as Annual Tax on Enveloped Dwellings (ATED). Company ownership may require a separate ATED assessment; this is not an ATED calculator.

When Must a Company File and Pay SDLT?

The usual deadline is 14 days after the effective date. This is often completion, but substantial performance can bring it forward. The calculator shows an indicative date when you enter the effective date; it does not file, pay or create an external reminder. A zero-tax estimate does not determine whether a return is required. Consult HMRC’s filing guidance.

Which Company Purchases Need Separate Advice?

The tool is intended for one company buying the whole interest for itself in a straightforward, unlinked transaction. It excludes:

• Mixed-use property, multiple dwellings and uncertain classifications.
• Trustee or nominee purchases, partnerships and joint-buyer structures.
• Connected-party transfers and transfers of existing property into your own company.
• Linked deals, non-cash or uncertain consideration, debt assumption and exchanges.
• Shared ownership and transitional contracts.
• Reliefs or exemptions other than the selected Schedule 4A corporate relief.
• New leases, extensions, variations, surrender/regrant and specialist assignments.
• Residential interests subject to another person’s lease with more than 21 years remaining.

For an existing lease, this version requires an original term longer than seven years and more than seven years remaining, as well as the other displayed scope conditions. Exclusion from this tool does not establish the tax treatment; it means a different assessment is needed.

Why Use Legal Sparrow’s Company Stamp Duty Calculator?

The calculator explains the treatment behind the number. It avoids assuming corporate relief, does not treat UK incorporation as proof of surcharge exemption, and does not add the company uplift twice. Comparison snapshots and downloadable reports preserve the assumptions so you can discuss the estimate with an adviser. The interface requires no account or installation. Its long-form guide is separate from the calculator so you can read the guidance without crowding the calculation screen.

Frequently Asked Questions

Does a company pay higher stamp duty on its first property?

For a supported qualifying residential purchase of at least £40,000, the company higher-rate rules apply even if it owns no other property. The tool does not offer a first-property exemption for a company.

What happens below £40,000?

For a supported standalone purchase below that threshold, the residential surcharges are not applied and the standard bands produce no tax. At exactly £40,000, the company higher-rate calculation applies. Linked and specialist transactions need separate assessment.

Is an SPV automatically entitled to the lower calculation?

No. An SPV describes the company’s purpose or structure, not an automatic SDLT relief. The actual transaction and any qualifying use determine the treatment.

Can the company claim first-time buyer relief?

This calculator does not apply first-time buyer relief to company purchases. A director’s personal first-time buyer status does not turn the company’s purchase into a personal home purchase.

Is the flat 17% charged only above £500,000?

No. When that flat charge applies, it applies to the full chargeable consideration. The threshold determines whether the regime is relevant, rather than creating a tax-free first slice.

Does qualifying rental-business relief mean no stamp duty?

No. Relief from the flat corporate charge normally leaves the company higher-rate bands applicable, with any relevant non-resident surcharge. The calculator displays this distinction.

Can I use this for Wales or Scotland?

No. Use the Welsh LTT calculator or Revenue Scotland’s LBTT calculators with the appropriate company details.

Can it calculate tax when I transfer my property to my company?

No. Connected-party and incorporation transactions can involve special valuation and relief rules. They are explicitly outside this tool’s scope.

Can I enter lease rent?

No. This company purchase calculator does not calculate rent NPV or tax on a newly granted lease. Its supported lease option concerns an existing-lease assignment under the stated conditions.

Why does the final total show whole pounds?

The engine aggregates the calculation using integer monetary values and rounds the final tax down to whole pounds. Displayed band contributions may include pence. See HMRC’s rounding guidance.

Are my inputs saved or shared?

The calculator code processes inputs locally and does not send them to a calculation server or save them persistently. Comparison snapshots last while the page is open. Copying, downloading or printing creates the copy you request. Wider website analytics and privacy practices are separate.

Are future rates guaranteed?

No. The engine uses rules checked on 16 October 2026 for supported effective dates from 1 April 2025. Future transactions are calculated on the assumption that those rules remain unchanged. Rates do not update automatically.
