What is GSTIN?

GSTIN, is short for Goods and Services Tax Identification Number a unique identification number that has been assigned to various dealers and service providers. The concept of GSTIN is being introduced basically for the facilitation of the people as well as government authorities involved in the taxation system throughout the country.


Earlier, under the state VAT system, all registered dealers were assigned a TIN number and Central Board of Excise and Custom was responsible to assign various service providers their service tax registration number. But under this new taxation system, all taxpayers are brought together under one single umbrella to smooth the way for various administrative processes. Therefore, all taxpayers will be assigned with a GSTIN.
