When should I opt to tax a property?

What "opt to tax" actually does

Most supplies of land and commercial buildings in the UK are exempt from VAT by default. That sounds like a relief, but it has a hidden cost: if your sales of the property (sales, leases, rentals) are exempt, you can't reclaim the VAT you incur on related costs such as the purchase, refurbishment, repairs, or professional fees.

Opting to tax flips that default. Once you've opted, your future supplies of the property become standard-rated at 20%, which then unlocks the right to reclaim the input VAT on related costs.

The mechanism only applies to commercial property. Dwellings, and certain types of residential and charitable buildings, can't be opted to tax. And it's not a one-off decision: an option, once made and notified, generally lasts 20 years.

When opting to tax usually makes sense

The case for opting tends to be strong when:

• You're buying or constructing a commercial property with significant VAT on the purchase price or build costs (think 20% of seven figures), and you want to reclaim that VAT
• Your tenants or buyers will be VAT-registered businesses that can reclaim the VAT you charge them, so the extra 20% on rent or sale price doesn't actually cost them anything
• You're undertaking a major refurbishment where input VAT recovery would meaningfully change the economics of the project
• You're a property developer or investor whose business model depends on recovering input VAT through opted properties

In all these cases, the recovered input VAT can be substantial, and the cost of charging output VAT to future tenants or buyers is minimal because they can reclaim it.

When opting to tax usually doesn't make sense

The case against opting tends to be strong when:

• Your tenants or buyers will be businesses that can't reclaim VAT, such as banks, insurance brokers, dentists, doctors, schools, charities, residential developers. Charging them 20% is real money out of their pocket, and it can affect rent reviews, tenant retention, and your ability to find buyers down the line
• You have limited or no input VAT to recover. Without recoverable costs, the option only creates additional output VAT obligations with no offsetting benefit
• Your long-term plan involves converting the property to residential or charitable use, where the option may need to be disapplied later and the mechanics get more complex
• You're holding the property for a short or uncertain term, where the 20-year commitment may outlive your actual involvement

Where this gets ambiguous: the "make sense / don't make sense" line isn't always clear. A landlord with a mix of VAT-recovering tenants and exempt-activity tenants, or one whose tenant mix may change over time, sits in exactly the kind of grey zone where the right decision today can become the wrong one in five years. Future tenant mix, exit strategy, and refurbishment plans all need to be part of the calculation.

The 20-year commitment, in practice

Once you've opted and the cooling-off period has passed, you're broadly committed for two decades. That means:

• 20% VAT on all rent invoiced from the property
• 20% VAT on the sale proceeds if you sell within that period
• The option continues to apply even if you change your business model, your tenant mix shifts, or your plans for the property change
• The option doesn't end when you deregister for VAT. If you later sell an opted property, you may need to re-register specifically to charge output VAT correctly

There are limited routes out before the 20 years are up (see below), but each comes with conditions and most aren't available on demand. Before opting, you should be reasonably confident that the decision still makes sense over a long horizon, not just for the immediate cost recovery.

The two-step process: decision and notification

An option to tax is technically two separate acts:

1. The decision to opt, made by the business (or person) holding the interest in the property. This is the moment the option takes effect economically
2. The notification to HMRC, which must be made within 30 days of the decision, typically using form VAT1614A

The 30-day deadline is strict. HMRC can accept a late notification in some circumstances, but reliance on that flexibility isn't a strategy. If you're going to opt, the notification needs to be on time.

Certain situations require prior permission from HMRC before you can opt at all. The main one is where exempt supplies of the property have been made in the previous ten years, in which case you need to apply on form VAT1614H, and permission isn't automatic. There are four specified conditions under which permission is granted without discretion, but determining whether your situation meets one of them is itself a technical question.

The 6-month cooling-off period

For 6 months after the option takes effect, you can revoke it by notifying HMRC on form VAT1614C. This is the only point at which the option can be undone without significant restrictions.

The catch is that several conditions all have to be met for cooling-off to be valid. Among them: no taxable supplies have been made under the option, no transfer of the property as a going concern has happened, and a number of other technical conditions. The window is real, but it's narrower in practice than the simple "6 months" framing suggests.

The expensive reality: a business opts to tax to reclaim input VAT on a refurbishment, then discovers in month four that their main tenant can't accept the 20% uplift. By that point, taxable supplies have usually been made, and cooling off is no longer available. The option then runs its 20-year course regardless.

Other routes out, and when they apply

Beyond the 6-month window, the option can end in three other ways, each with its own mechanics and constraints:

The 6-year automatic revocation

If you cease to hold an interest in the property and 6 years pass without you acquiring a new interest in it, the option is automatically revoked. This is the only "do nothing" route to ending an option, but it requires actually parting with the property and staying away from it for the full period.

The 20-year revocation

After 20 years have passed since the option took effect, you can apply to revoke it using form VAT1614J, with HMRC's permission. Whether revocation makes sense at this point depends on your current tenant base, your plans for the property, and how the property's VAT history affects future supplies.

Disapplication and exclusion

In specific circumstances (new buildings on opted land, conversions to dwellings, sales to housing associations), the option can be disapplied or specific buildings excluded using specialised forms. Each of these has detailed conditions, and getting them right matters because mistakes here often have permanent consequences.

The buyer / tenant question (it's bigger than it looks)

The economic case for opting depends heavily on who'll be paying the VAT you charge on rent or sale price. If they can reclaim it, the option costs them nothing. If they can't, you're charging them 20% more, and that has consequences:

• Tenants who can't reclaim VAT (banks, dentists, healthcare providers, schools, charities) will resist or refuse to pay it. They may negotiate the rent down to compensate, or they may simply walk to a non-opted comparable property
• Buyers who can't reclaim VAT have the same problem at a larger scale. A £750,000 freehold sale that's opted suddenly carries £150,000 of VAT for the buyer, which they can't recover. Many will either pull out, renegotiate, or insist on TOGC (transfer as going concern) treatment, which has its own conditions
• A surprise option (where the seller had opted years ago and forgot to mention it) can derail a transaction at exchange. This happens more often than you'd think

Before opting, the question "who are my future tenants and buyers, and can they reclaim VAT?" is at least as important as "how much input VAT will I recover today".

What you need to do, step by step

1. Confirm the property is commercial (the option doesn't apply to dwellings) and that you actually hold an interest in it that can be opted
2. Check whether prior permission from HMRC is needed, particularly if exempt supplies have been made on the property in the last 10 years
3. Run a long-term financial model covering input VAT recovery, output VAT on rent or sale, expected tenant mix, refurbishment plans, and exit timing, over the full 20-year horizon
4. Discuss the decision with current and prospective tenants or buyers if you have any, to understand how the option will land commercially
5. Make the decision formally and document it, with the effective date clearly recorded
6. Notify HMRC within 30 days on form VAT1614A (or VAT1614H if prior permission is required), and keep proof of submission
7. Track the 6-month cooling-off window in case circumstances change and you need to reconsider
8. Update your accounting systems to charge VAT on rent and sales from the effective date

The situations that most often turn into costly mistakes

Option to Tax is one of the most consequential VAT decisions a business can make. The mechanics are technical, the commercial implications are wide-ranging, and the commitment is long. In practice, the situations below are where the decisions most often go wrong, sometimes for years, before the cost surfaces:

• You're about to buy or construct a commercial property with significant VAT involved, and want a clear-eyed view on whether opting is the right move
• You're planning a major refurbishment and the input VAT recovery would materially affect the economics
• Your tenant mix is mixed or evolving, and you're not sure how an option would land across the full base
• You think your property may need HMRC prior permission and you want to know which route applies
• You've already opted and are within the cooling-off period, and need to decide whether to revoke
• You're selling a property that was opted years ago, and want to handle the VAT treatment cleanly
• An opted property is being converted to residential use, or sold to a buyer who can't reclaim VAT, and you need the right approach
• You've just realised an option exists on a property and don't know what your current obligations are
• You've received a letter from HMRC about an Option to Tax matter and aren't sure how to respond
