Early GST registration gives you:

  • Negotiation power

  • Faster onboarding with clients

  • Smooth invoicing from day one

Think of GST as a growth tool, not just a tax rule.

Common Mistakes Small Businesses Make During GST Registration

Learning from others’ mistakes can save you time and money.

1. Choosing the Wrong Business Type

Registering as a proprietorship when you plan to convert into a company soon leads to duplicate compliance.

Wrong codes can create tax mismatches and notices later.

GST doesn’t end at registrationreturns and filings are equally important.

4. Registering Under Composition Scheme Without Understanding Limits

Many service startups mistakenly choose composition and later regret it.

5. Not Updating Business Details

Change in address, bank, or business activity must be updated on the portal.
