To benefit from the VAT rate reduced to 5.5% for a real estate purchase, the new housing in VEFA must be built in an urban development and renovation zone (ANRU) or in a perimeter of 300 meters around.
Since January 2015, this rate also applies to housing located in a priority neighborhood of the city policy (QPV). In addition, the property acquired must be the principal residence of the purchaser. Since January 1, 2014, the owner of a new property can sell his property without losing his tax advantage, if he sells it after 10 years. This new rule is not retroactive and concerns the supply of housing as of 1 January 2014.
For deliveries before 1 January 2014, the deadline for avoiding the loss of the tax advantage at the time of sale is 15 years. However, the law provides for exceptions which exempt from payment of the VAT supplement in the event of early resale.
