SDLT on commercial property: how VAT increases the stamp duty bill

Yes, in most cases. SDLT applies to non-residential and mixed-use purchases in England and Northern Ireland once the price passes the nil rate threshold, whether you are buying a freehold, taking a new lease or paying a premium on an assignment. Scotland charges Land and Buildings Transaction Tax and Wales charges Land Transaction Tax instead, so the rules and rates differ if the property sits outside England or Northern Ireland.

The tax is worked out in bands on the chargeable consideration, which is essentially everything of value you give for the property. Reliefs and exemptions exist for certain transfers, and leases are taxed differently from freehold sales, but the default position for a commercial purchase is that SDLT is payable. You must file an SDLT return and pay what is due, normally within 14 days of completion.

SDLT on commercial property is charged at progressive rates in bands, so you pay a rising percentage on each slice of the purchase price above the nil rate band, not a single flat rate on the whole figure. Freehold and premium payments use one set of non-residential bands, and new leases carry a separate charge based on the net present value of the rent over the term.

Because the rates and thresholds are set by HMRC and can change at fiscal events, we do not quote fixed figures here. Check the current non-residential bands on the gov.uk Stamp Duty Land Tax pages, or use HMRC's SDLT calculator, to see exactly how much you will pay on a given commercial property. What matters for planning is the base the tax is applied to, and that is where VAT comes in.

SDLT is charged on the total consideration you pay, and where VAT is due on the purchase that consideration is the VAT-inclusive price. So if a commercial property is sold with VAT at the standard rate of 20%, the SDLT is calculated on the price plus the VAT, not on the net purchase price alone. The VAT charge therefore has a knock-on effect: it raises the figure the SDLT bands are applied to, and pushes more of the price into higher bands.

This only happens when VAT actually applies. Many commercial properties are exempt from VAT by default, in which case there is no VAT and no uplift to the SDLT base. But once a seller has opted to tax, the sale becomes standard rated, VAT is added, and both your VAT cost and your SDLT cost rise together. That is why we say VAT planning on a commercial purchase is really SDLT planning too.

Whether VAT is charged usually turns on two concepts. The option to tax is a decision the seller makes to charge VAT on what would otherwise be an exempt commercial property; once made, it makes the sale standard rated and adds 20% to the price, which then flows through into the SDLT base. If you are the buyer, confirming the VAT status early tells you whether to budget for that extra VAT and the extra SDLT it triggers.

A transfer of a going concern, or TOGC, works the other way. Where a let commercial property is sold as a continuing business and the strict conditions are met, no VAT is charged on the sale at all. No VAT means no uplift to the consideration, so the SDLT is calculated on the price alone. TOGC treatment is powerful but conditional, and getting it wrong is costly, so always confirm the position with your solicitor and accountant before completion.

There is no legitimate way to make SDLT disappear on a standard commercial purchase, and we would treat any scheme promising that with real caution. What you can do is plan properly so the bill is no larger than it needs to be and does not surprise you at completion:

• Confirm the VAT status of the property in writing before you exchange, so you know whether the option to tax applies and VAT will be added.
• Check whether the sale qualifies as a TOGC, which removes the VAT and therefore the VAT-driven uplift to your SDLT.
• Factor the VAT-inclusive figure into your SDLT estimate from the outset, rather than budgeting on the net price.
• Consider any reliefs your transaction may qualify for, and take advice on mixed-use treatment where a property has both commercial and residential parts.

None of this is tax advice, and the right answer depends on your circumstances, so use a solicitor and accountant to confirm the treatment on your specific deal.

When VAT does apply, you generally have to pay it at completion even though you expect to recover it. If you are VAT registered and buying for a taxable business use, you reclaim the VAT from HMRC on your next VAT return, and the HMRC VAT refund typically arrives within roughly one to three months. In the meantime the cash is out of your business, on top of the deposit, the SDLT and your other costs.

This is the gap a VAT bridging loan is built for. A VAT bridge is short term finance that funds the 20% VAT at completion so you are not tying up your own working capital, and it is repaid when the VAT refund comes back from HMRC. The exit is the refund itself, so the term is short and interest can often be rolled up. We are a broker, not a lender, and VAT bridging on commercial property is unregulated commercial finance rather than a regulated mortgage, so speak to us and your advisers about whether it fits your purchase.
