GST Registration involves the process of enrolling a business under the Goods and Services Tax framework to obtain a GSTIN. While the process itself is usually straightforward, businesses commonly run into avoidable issues along the way. Here are the mistakes we see most often, and how to steer clear of them.

Mistake 1

Applying with mismatched name/address across PAN and other documents.

Mistake 2

Choosing the wrong business constitution type.

Mistake 3

Missing the deadline once turnover crosses the threshold.

Mistake 4

Not planning for return filing before registration is even approved.

How to Avoid These Issues

Most of these mistakes come down to preparation. Having the right documents ready — PAN of the business or proprietor, Aadhaar and address proof of the applicant, Proof of business premises (utility bill, rent agreement or NOC), among others — and understanding the process before you start goes a long way toward a smooth outcome with the GST portal, administered jointly by central and state tax authorities.

Quick Reference: What You'll Need

  • PAN of the business or proprietor
  • Aadhaar and address proof of the applicant
  • Proof of business premises (utility bill, rent agreement or NOC)
  • Bank account details or a cancelled cheque
