How to get PAN From GSTIN in ax 2012

What is Goods and Services Identification number (GSTIN)?

All the business entities registering under GST will be provided a unique identification number known as GSTIN or GST Identification Number.

Currently any dealer registered under state value added tax (VAT) law has a unique TIN number assigned to him by state tax authorities. Similarly, Service Tax Registration Number is assigned to a service provider by Central Board of Excise and Customs (CBEC).

Under GST regime, all these parties will come under one single authority and the different identification numbers(IN) that will be replaced by a single type of registration number for everyone i.e.,  Goods and Services Identification number (GSTIN). This will ensure better administration by the authority and greater compliance by taxpayers and hopefully improve tax collection.

The first 2 digits of the 15 digit GSTIN will represent the state code.

The next 10 digits will be the PAN number of person or firm engaged in Business.

As proposed the State Code as defined under the Indian Census 2011 would be adopted In the GSTIN. As per the terms of the Indian Census 2011, every State has been allotted a unique two digit code. For 01 for Jammu and Kashmir, 02 for Himachal Pradesh, 03 for Punjab.

The 13th would represent the number of registrations an entity has with in a state under the same PAN. It will be an alpha-numeric number (first 1-9 and then A-Z) and will be assigned on the basis of a number of registrations a legal entity (having the same PAN) in the same state.
