VAT on commercial property

Disapplying the Option to Tax

PropertyVAT Team · Updated 21 October 2026 · 3 min read

Most buyers treat a seller's option to tax as settled: they have opted, so 20% is payable. In certain circumstances that is wrong, and the VAT disappears entirely.

Disapplication is not widely understood, and on the deals where it applies it is worth more than any funding arrangement.

What disapplication means

Where the rules provide for it, a seller's option to tax is overridden for a particular supply. The sale reverts to being exempt, and no VAT is charged.

It is not a concession either party grants. It follows from the facts, the buyer's intended use, and — for the routes that matter most — a certificate given by the buyer to the seller.

The routes that matter to buyers

Relevant residential purpose. Where the building will be used for a qualifying residential purpose — care homes, certain student accommodation, children's homes and similar — an option can be disapplied on certification by the buyer.

Relevant charitable purpose. Where a charity will use the building for a non-business purpose, or as a village hall or similar, disapplication can apply on the same certification basis.

Conversion to dwellings. Where the buyer intends to convert the building into dwellings, there are circumstances in which the option is disapplied.

Anti-avoidance provisions. A separate set of rules can disapply an option where the arrangements fall within specific anti-avoidance tests. These are technical and usually a matter for advisers rather than a planning tool.

Why it is worth more than funding

Compare three outcomes on a £4m building where the seller has opted:

For a buyer who could recover the VAT, disapplication saves the funding cost and the extra stamp duty.

For a buyer who could not recover — a care operator, a charity, a residential landlord — it saves the entire £800,000. That is the difference between a viable acquisition and an unviable one.

Which is exactly the point: the routes exist for buyers whose own supplies would be exempt, and who would otherwise bear VAT permanently.

The certificate and its timing

For the residential and charitable routes, the buyer typically certifies their intended use to the seller using the prescribed form, within the required timeframe — generally before the supply takes place.

Three practical consequences:

1. It is the buyer's action. The seller cannot do it for you.
2. It is deadline-driven. Late certification can fail, and the VAT then applies.
3. It carries obligations. Certifying an intended use you do not then follow has consequences, including potential clawback.

So it belongs early in the conveyancing timetable, alongside VAT registration and any option to tax of your own.

The seller's side

Disapplication is not cost-free for the seller. An exempt sale can affect their own recovery position, including under the Capital Goods Scheme if the property is still within its adjustment period.

Expect that to show up in negotiation. A seller facing a clawback may seek to reflect it in the price. That is a commercial conversation worth having early rather than discovering as an eleventh-hour adjustment.

What to do

1. Establish the seller's option — notification and acknowledgement.
2. Identify your intended use precisely. Residential purpose, charitable purpose, conversion to dwellings, or ordinary commercial use.
3. Ask your VAT adviser whether a disapplication route is available. Do not assume it is, and do not assume it is not.
4. If it is, certify properly and in time, using the prescribed form.
5. Expect the seller to raise price consequences, and build that into the negotiation.
6. Have a funding plan in case the route does not apply after all.

Point three is the one that gets skipped. The routes are narrow, but on a building where you could not have recovered the VAT anyway, the question is worth a specialist's hour.

This guide is general information, not tax advice. Disapplication depends on specific conditions, certification and timing — take specialist VAT advice before exchange.
