Frequently Asked Questions (FAQ)



What if my PAN is not Aadhar-linked? Can I still register?


+


Yes, you can register with a non-Aadhar-linked PAN. However, the process might require additional verification by GST authorities. It's recommended to link your PAN with Aadhar first (takes 5-10 minutes on the IT website) to expedite approval. Non-Aadhar-linked applications may take 10-15 days for approval.





Is there a minimum turnover requirement for voluntary GST registration?


+


No. Any business, regardless of turnover, can voluntarily register for GST. In fact, businesses with <₹40 lakh turnover often voluntarily register to claim input tax credit (ITC) on their purchases, which reduces their overall tax burden.





How long does it take to receive my provisional GSTIN?


+


Your provisional GSTIN is usually issued within 1-3 days of application submission. You'll receive an email notification with your provisional GSTIN. You can start filing GST returns using this provisional number. Final approval typically happens within 3-7 days.





Can I register from home or do I need to visit an office?


+


GST registration is entirely online. You don't need to visit any GST office or counter. The entire process can be completed from your home or office in 15-20 minutes on gst.gov.in. No physical verification is required for most applications.





What if my application is rejected? Can I reapply?


+


Yes, you'll receive an email explaining the reason for rejection. Common reasons include incorrect documents, address mismatch, or eligibility issues. You can correct the information and reapply immediately. Keep your ARN for reference. Most rejections are due to fixable issues like document quality or data entry errors.





Is GST registration really free or are there hidden charges?


+


GST registration is 100% free. There are absolutely no registration fees, application charges, processing fees, or hidden costs. The government portal (gst.gov.in) is the only official channel. Be cautious of third-party websites offering "faster registration" - they're scams.
