Step-by-Step Registration Process includes: Visit the GST Portal — Go to gst. gov.

1. Visit the GST Portal — Go to gst.gov.in and click "Register Now" under "Taxpayers"
2. Part A: Generate TRN — Enter PAN, mobile number, and email. Verify via OTP to receive a Temporary Reference Number (TRN)
3. Part B: Complete application — Log in with TRN and fill in business details, promoter/partner information, authorized signatory, place of business, and bank details

Composition Scheme: The Small Business Alternative

Businesses with turnover up to ₹1.

Businesses with turnover up to ₹1.5 crore (₹75 lakh for special category states) can opt for the Composition Scheme:

• Lower tax rates — 1% for manufacturers, 5% for restaurants, 6% for service providers
• Simplified returns — quarterly CMP-08 instead of monthly GSTR-1/3B
• Less compliance burden — no e-invoicing or detailed HSN reporting

However, composition dealers cannot claim ITC, make interstate supplies, or supply through e-commerce platforms.

Common Registration Mistakes to Avoid

Common Registration Mistakes to Avoid includes: Wrong PAN type — using personal PAN for a company (must use company PAN) Address mismatch — business address on application doesn't match supporting documents

• Wrong PAN type — using personal PAN for a company (must use company PAN)
• Address mismatch — business address on application doesn't match supporting documents
• Missing state registrations — if you operate in multiple states, you need separate GSTIN per state
• Not registering for e-commerce — e-commerce sellers must register even below threshold
• Delayed registration — penalties apply from the date registration was due, not from the date you apply
