Lianyungang tax bureau sharpens supervision with big data

The discipline inspection team at Lianyungang's tax bureau has put big-data tools to work in supervision. Together with business departments it targeted problem-prone areas such as invoice management and risk response, setting more than 60 internal control indicators to catch anomalies, and added 18 more covering matters like lapsed property tax filings and disability employment fund cases that should have been identified. Recently staff from the collection and management division screened digital invoice anomalies on the internal control platform, found four types of alerts including irregular category upgrades before deregistration, verified them one by one and passed leads to the audit and inspection department and then to the inspection team. The bureau also formed a smart supervision team and a policy support team that run penetrating analysis on anomalies flagged by several indicators at once, once drawing out two suspected disciplinary leads and one suspected export tax refund fraud lead; the inspection department and police opened a case that busted the fraud ring and produced evidence of staff misconduct. In 2025 the approach handled six cases combining review with accountability and checked five companies in both directions.
