This data product and service is developed based on data resources including real estate online signed contract filing records and value-added tax (VAT) declaration documents, and features a function to identify the risk of discrepancy between real estate enterprises' sales revenue and their filed contract amounts. The model compares the online registered and filed amounts of enterprises across three sales stages—presale, completed real estate, and mixed sales—with their declared (prepaid) sales revenue in corresponding periods. It can serve tax authorities, helping them proactively detect tax compliance risks such as enterprises' failure to declare their income timely and in full, and provide accurate risk early warning support.
