The VAT option to tax (OTT) is one of the most powerful and frequently misunderstood tools available to UK property owners and investors. Getting it right can unlock thousands of pounds in recoverable input VAT. Getting it wrong can result in unexpected VAT bills, invalid elections, and costly disputes with HMRC. This guide explains everything you need to know for 2026, including when to opt, how to notify HMRC, and the downstream implications for landlords, developers, and commercial property buyers.
By default, the sale or letting of land and buildings in the UK is exempt from VAT. This sounds beneficial but creates a significant problem: if transactions are exempt, the business cannot recover the VAT it pays on related costs such as construction work, architectural fees, legal expenses, and refurbishment. This is known as “blocked input tax.”
The option to tax allows a VAT-registered person or business to waive this exemption for a specific property and instead charge VAT at the standard rate of 20% on rents and sale proceeds. In return, they can reclaim the input VAT incurred on costs associated with that property.
The legal basis for OTT sits in Schedule 10 of the Value Added Tax Act 1994, and the practical rules are set out in HMRC Notice 742A. The election is made by the individual or entity, not by the property itself—but once made, it binds them to that property for 20 years unless specific revocation conditions are met.
The option to tax applies to non-residential land and commercial buildings. This includes:
It does not apply to:
HMRC is strict on the residential exclusion. Even if a developer plans to convert a commercial building to residential, they cannot opt the residential element. Partial OTT is not possible on a single building where part is residential and part commercial—the entire building must be treated as either opted or unopted for each distinct legal interest.
Making a valid OTT involves two distinct steps that are often confused:
The election itself is a unilateral decision by the landowner or tenant. For most businesses, this simply means deciding to opt. However, if the business has charitable purposes or intends to use the property for exempt or non-business activities, HMRC permission may be needed before the election is valid.
You must notify HMRC of your election within 30 days of making it using form VAT1614A (Option to Tax Notification). This can be submitted:
If you do not notify within 30 days, the option is not effective until HMRC receives it. This can create a gap where you have charged VAT before the option is valid—a common and expensive mistake in fast-moving commercial property transactions.
Keep a copy of the submitted form and HMRC’s acknowledgment. HMRC no longer automatically issues acknowledgment letters; instead, you receive a digital confirmation. Retain this in your property records indefinitely—you may need to prove the option exists many years later on a sale.
In most cases, businesses can make an OTT election without asking HMRC first. However, you need HMRC permission (via form VAT1614H) before your election is valid if:
Most straightforward commercial landlords and developers will not need permission. However, property investors who have previously let a building as exempt before deciding to opt should seek professional advice to check whether the permission route applies.
Once an OTT is in place, a landlord must charge VAT at 20% on all future rents for the opted property. For example, a commercial tenant paying £5,000 per month rent will now be invoiced £6,000 per month (£5,000 + £1,000 VAT).
This has important implications:
Landlords must also ensure their lease agreements reflect the VAT status correctly. Many commercial leases include a VAT clause stating that rent is stated exclusive of VAT and that VAT will be added at the prevailing rate. Check your lease before opting—some older leases may specify rent is VAT-inclusive, which affects the economics significantly.
If you sell a property on which you have opted to tax, VAT at 20% is normally due on the sale price. A commercial property selling for £500,000 would carry a VAT liability of £100,000, making the total cost to the buyer £600,000.
This can be avoided in two main ways:
If the sale constitutes the transfer of a business as a going concern, it falls outside the scope of VAT entirely. For a let commercial property, TOGC treatment typically applies when:
TOGC treatment removes the £100,000 VAT from the example above, saving the buyer significant acquisition costs and the seller the administrative burden of accounting for output tax.
In limited circumstances, the option to tax can be disapplied on a sale—for example, when selling to a “relevant housing provider” for conversion to residential use, or to a charity for non-business use. In these cases, even if you have opted, the sale remains exempt.
The Capital Goods Scheme applies to land and buildings where the VAT-exclusive cost exceeds £250,000. Under CGS, you must monitor and potentially adjust your VAT recovery over a 10-year adjustment period if the use of the property changes.
For example, if you opt a building and recover £50,000 of input VAT on a refurbishment in year 1, but then in year 4 you de-opt or start making exempt supplies from the building, HMRC will require you to repay a portion of the recovered VAT (6 out of 10 intervals remaining).
This makes OTT decisions even more significant for major capital projects. Businesses embarking on substantial developments should model the CGS implications over the full 10-year window before deciding whether to opt.
Once made, an OTT election is binding. You can revoke it only in specific circumstances:
| Scenario | Revocation Window | Conditions |
|---|---|---|
| Cooling-off period | Within 6 months of election | No VAT charged and no input tax claimed under the option |
| Standard revocation | After 20 years | Option has run its full term; use form VAT1614J |
| Early revocation (with HMRC permission) | Before 20 years | Significant change in use; apply using VAT1614J with explanation |
| Automatic lapse | N/A | Property converted entirely to residential use and no interest remains |
Using form VAT1614J is required to formally notify HMRC of revocation. As with the original election, record-keeping is critical—you need evidence of when the revocation took effect, especially if subsequent sales or lettings are intended to be exempt.
Only VAT-registered businesses can make an option to tax election. If your total taxable turnover (including opted rents or sales proceeds) exceeds the VAT registration threshold of £90,000 per year, you must register for VAT. Opting to tax a property that generates rental income above this threshold will therefore trigger a mandatory registration obligation.
Conversely, a landlord with small exempt rental income may opt specifically to recover input VAT on a major refurbishment. Once the option is in place and they begin charging VAT, they must monitor whether taxable turnover breaches £90,000. Voluntary registration is also available below this threshold.
Consider a property developer who purchases a derelict warehouse for £300,000 plus VAT of £60,000. They plan to refurbish it at a cost of £200,000 plus VAT of £40,000, then let it commercially at £60,000 per year.
Without OTT: The letting is exempt. The developer cannot recover the £100,000 of input VAT paid on purchase and refurbishment. That £100,000 becomes a sunk cost.
With OTT: The letting is taxable at 20%. The developer charges £12,000 VAT per year on rents (£60,000 x 20%) and can immediately recover the £100,000 of input VAT incurred on purchase and refurbishment. The net VAT recovery in year 1 is £100,000 minus £12,000 output = a VAT repayment of £88,000 from HMRC, dramatically improving cash flow.
The trade-off is that VAT-registered tenants are unaffected, but non-VAT-registered tenants face a 20% surcharge on their effective rent costs. For a warehouse likely occupied by trading businesses that are VAT-registered, this trade-off is usually strongly in favour of opting.
For context, the UK VAT rates applicable in 2026 are:
| Rate | Percentage | When It Applies |
|---|---|---|
| Standard rate | 20% | Most goods and services, opted commercial property |
| Reduced rate | 5% | Energy, residential conversions in certain cases, children’s car seats |
| Zero rate | 0% | New residential builds, food, books, children’s clothing |
| Exempt | N/A | Non-opted land and property, insurance, finance |
The VAT registration threshold remains at £90,000 for 2026/27. Businesses below this threshold may voluntarily register if opting to tax makes input tax recovery commercially advantageous.

Think carefully before opting when:
The option to tax is a long-term commitment and its implications extend across every subsequent sale, letting, and development. Always take specialist VAT advice before making or revoking an election on any significant commercial property transaction.
