Explanation:

Tax Information Exchange System (TINXSYS) is a centralized exchange of all interstate dealers spread across the various States and Union territories of India. 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 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.
