GST REG-06 explained: your GST registration certificate

What the certificate shows

The main certificate lists the GSTIN, legal and trade names, constitution of business, principal place of business, date of liability and the date of issue. Annexure A lists additional places of business and Annexure B lists the proprietor, partners, directors or Karta. The same form is used to issue certificates to TDS deductors, TCS collectors, non-resident taxable persons, OIDAR suppliers and UIN holders.

Effective date

If you applied within 30 days of becoming liable, registration is effective from the date of liability. If you applied later, it is effective from the date of grant. For voluntary registration, it is effective from the date of the order. A casual or non-resident taxable person gets a certificate valid for the period stated, which can be extended.

Display and use

Rule 18 requires the certificate to be displayed prominently at the principal place of business and every additional place, and the GSTIN to be shown on the name board at the entry. The certificate is downloaded from Services, User Services, View or Download Certificates.

First things to do after REG-06

• Add bank account details within 30 days, or before your first GSTR-1 or IFF, to avoid suspension under Rule 10A
• Note your return filing frequency and due dates
• Set up invoice series with your GSTIN
• Check the Invoice Management System for supplier invoices once you start purchasing
• Keep the principal place functional and the board displayed, since officers may verify

Corrections

Errors in name, address or partners are corrected through an amendment application in REG-14, not by reissuing the certificate manually. A professional can handle both the amendment and the first months of returns.
