VAT: Overages – new guidance

By   6 October 2025

HMRC has issued new internal guidance on overages.

Land and property transactions are often complex and high value for VAT purposes. One area which we have been increasingly involved with is overages.

What is an overage?

An overage is an agreement whereby a purchaser of land agrees to pay the vendor an additional sum of money, in addition to the purchase price, following the occurrence of a future specified event that enhances the value of the land. This entitles the seller to a proportion of the enhanced value following the initial sale. Overages may also be called clawbacks, or uplifts.

Overages are popular with landowners who sell with the benefit of development potential and with buyers who may be able to purchase land at an initial low price with a condition that further payment will be made contingent on land increasing in value in the future – this may be as a result, of, say, obtaining Planning Permission.

VAT Treatment

HMRC consider that the VAT liability of overage should be considered separately from the VAT liability of the initial sale. HMRC’s policy is that the VAT liability of an overage payment will generally be determined at the time of supply of the overage payment, rather than when the original land sale completed.

Overage payments where an option to tax is made after the initial grant – where an option to tax is made after the property has been sold to the buyer, any subsequent overage payment may be liable to the standard rate of VAT as a result of VAT Act 1994, Schedule 10, Paragraph 31 (unless the option to tax has been disapplied, eg; where a property intended for use as a dwelling). In such situations, where the overage payment is made after the dwellings are constructed on the land, and the original grant was taxable by virtue of the option to tax, the option can be excluded in relation to the overage payment.

New commercial buildings – overage payments:

  • Where there is a grant of a freehold interest in a new (or incomplete) commercial building, the overage will always be taxable at the standard rate – it does not become exempt simply because three years or more have elapsed since the building was completed. This will remain the position if the overage falls due after the designation ‘new’ has expired after three years.  
  • Where there has been a freehold sale of bare, un-opted land subject to an overage obligation, the liability of the overage payment will remain exempt even if a new commercial building is constructed on the site before the overage is paid. 

This means that the VAT liability of the overage is determined by reference to the description of the land at the time that the original sale of the land takes place.

VAT: Construction of a dwelling – zero-rated? The CMJ (Aberdeen) case

By   18 August 2021

Latest from the courts

The First-Tier tribunal (FTT) considered the case of CMJ (Aberdeen) Limited (CMJ) and whether the supply of building services in respect of the construction of a dwelling were correctly zero rated by the appellant. HMRC deemed that the construction services were standard rated on the basis that the works were not carried out in accordance with the terms of the relevant statutory planning consent.

Background

HMRC’s view was that, although planning consent was in place at the time the construction services were supplied by the appellant, that planning consent permitted only the alteration or enlargement of a dwelling and did not allow for the construction of a dwelling. HMRC accept that the property was constructed as a new building, but that this was not permitted by the planning consent and so the construction was not carried out in accordance with it.

CMJ contended that statutory planning consent had been obtained for the construction via a combination of the planning consent and a construction building warrant which it had obtained from the relevant authority, and which allowed for the construction of a new building.

Legislation

The zero rating for the construction of new dwellings is contained in The VAT Act 1994, Schedule 8, Group 5, item 2

“The supply in the course of the construction of

(a)     a building designed as a dwelling…”

Note 2 to Group 5 of Schedule 8 to the VAT Act include the following:

“(2)  A building is designed as a dwelling or a number of dwellings where in relation to each dwelling the following conditions are satisfied…

…(d)   statutory planning consent has been granted in respect of that dwelling and its construction or conversion has been carried out in accordance with that consent.

Decision

The appeal was dismissed. It was judged that the building warrant did not comprise statutory planning consent for the purposes of note 2 (d) because:

  • Planning consent and building warrants operate under different statutory regimes.
  • Breach of planning consent is dealt with separately from a breach of the building warrant legislation, and each is dealt with by the specific statutory regime . If there is a breach of planning consent, it would not affect the validity of the building warrant, and vice versa.
  • The Building Standards Handbook states that the purpose of the building standards system is setting out the standards to be met when building work takes place. This is different from planning consent which is consent to allow the authority to permit development on a piece of land. They are distinct and separate regimes aimed at distinct and separate issues. While planning permission is about how the house will look, a building warrant is about whether it meets building standards.
  • Both planning permission and a building warrant is required. One is no substitute for the other.
  • It is possible to obtain retrospective planning consent, the judge did not believe it is possible to get a retrospective building warrant.

It was not possible to carry out works of construction in accordance with a valid statutory consent, since no such consent had been given for construction at the time that the building works were carried out.

Commentary

The legislation covering building work is complex and there are many traps for the unwary. Even the seemingly straightforward matter of whether a new dwelling is constructed can produce difficulties, as in this case. We always counsel that proper VAT advice is sought in such circumstances.
