Frequently Asked Questions

How long does it actually take to get a GST number?

Once you submit your application and verify it via OTP or DSC, the GST officer reviews it within 3 working days. If all your documents match up perfectly, your GSTIN is usually issued within 7 working days. If they raise a query regarding your address proof or PAN, it can delay the process by another week.

Can I apply for GST registration without a business bank account?

Yes, you can initiate the application process without a formal current account. The government allows you to submit your bank account details later. You just need to update your bank information on the GST portal within 45 days of getting your GSTIN.

What goes wrong if I accidentally register for the wrong GST category?

Registering under the wrong category (like choosing the Composition Scheme when you actually plan to sell cross-state) restricts how you operate. You won't be able to claim input tax credit or collect tax from customers. You'll need to formally apply to cancel the existing registration and apply for a new one, which halts your billing temporarily.

Is physical verification of my shop or office mandatory for GST?

It's not mandatory for every single application, but GST officers do conduct physical verifications if they flag a risk in your application. If your Aadhaar authentication fails or you opt out of it during registration, physical verification of your business premises becomes highly likely before approval.

Do I actually need a GST number if I only sell on Amazon?

Yes, you absolutely need one. Anyone operating as an e-commerce seller is required to have a GSTIN regardless of their annual turnover. There is no ₹40 lakh exemption limit when you sell goods through platforms like Amazon or Flipkart.
