According to Decree 339, real estate developers in Việt Nam could face fines ranging from 240 million to 300 million đồng for accepting cash payments as stipulated in contracts. The new regulation aims to increase transparency and combat illicit financial flows within the property sector. This decree applies to all real estate projects operating within Việt Nam. Authorities are prioritizing non-cash transaction methods to improve financial tracking and accountability. The penalties are intended to deter developers from circumventing financial regulations. Failure to comply with the decree could result in significant financial repercussions for project owners. This move signifies a broader effort by the Vietnamese government to regulate the real estate market.
