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.
