Tax Information Exchange System (TINXSYS) is a centralized exchange of all interstate dealers spread across the various States and Union territories of India. TINXSYS is an exchange authored by the Empowered Committee of State Finance Ministers (EC) as a repository of interstate transactions taking place among various States and Union Territories. TINXSYS will help the Commercial Tax Departments of various States and Union Territories to effectively monitor the interstate trade.

TINXSYS can be used by any dealer to verify the counter party interstate dealer in any other State. Apart from dealer verification Commercial Tax Department officials will use TINXSYS for verification of central Statutory Forms issued by other State Commercial Tax Departments and submitted to them by the dealers in support of claim for concessions. TINXSYS will also provide MIS and Business Intelligence Reports to the Commercial Tax Departments to monitor interstate trade movements and will enable EC to monitor the trends in interstate trade. TINXSYS will be used as an effective centralized tool for verification and monitoring of interstate trade in post VAT scenario.
