Jiangsu Tax Strengthens Large-Enterprise Compliance With Group Credit Governance and Digital Validation

China Tax News reported on July 29, 2026 that Jiangsu tax authorities are building a coordinated governance model for large enterprise groups with many subsidiaries, long industrial chains, and heavy tax workloads. Public reporting says Jiangsu issued a Large Enterprise Tax Internal-Control Compliance Guide that standardizes risks and control points across investment decisions, contract management, and procurement supply chains, while embedding credit guidance, reminders, repair, and incentives into daily service. In Nanjing, tax teams maintain a dynamic cultivation pool for A-grade taxpayers and issue warnings when credit conditions fluctuate abnormally across group members. In other cities, internal-control testing, tailored credit health checks, and risk reports help companies form a closed-loop governance process. The report also notes that Daya Technology Group is upgrading its tax-management module so business data can be automatically matched with tax filings, validated intelligently, and monitored through system alerts, showing tax informatization moving deeper into enterprise compliance and group-level credit management.
