GST Registration Online — Process, Documents & CA-Filed, Pan-India

GST registration in India is done online on the GST portal and typically takes 3–7 working days once documents are in order. It is mandatory above ₹40 lakh annual turnover for goods (₹20 lakh for services; lower thresholds in special-category states), for inter-state supply, and for selling through most e-commerce operators. MobiFirm's in-house team prepares and files the application for you, replies to any departmental queries, and hands you a clean GSTIN — quoted transparently before we start, serving businesses across India.

Who must register for GST

  • Businesses selling goods with annual turnover above ₹40 lakh (₹20 lakh in special-category states)
  • Service providers with turnover above ₹20 lakh (₹10 lakh in special-category states)
  • Anyone making inter-state taxable supplies, regardless of turnover
  • Sellers on e-commerce platforms where the operator collects TCS — registration is generally required regardless of turnover
  • Voluntary registration: many small businesses register early to claim input tax credit and look credible to B2B buyers

Documents you need

  • PAN and Aadhaar of the proprietor / partners / directors
  • Passport-size photo
  • Business address proof — electricity bill, rent agreement with owner's NOC, or property tax receipt
  • Bank proof — cancelled cheque or bank statement
  • For companies and LLPs: certificate of incorporation and board resolution / authorisation letter

How the process works with us

  • 1. Share documents on WhatsApp or email — we check them the same day and tell you if anything is missing.
  • 2. We prepare and file — application drafted and submitted on the GST portal with Aadhaar authentication.
  • 3. We handle queries — if the department raises a clarification, we draft and file the reply.
  • 4. You receive your GSTIN — usually within 3–7 working days, with guidance on invoicing and your first filings.

After registration: filing is the real work

A GSTIN comes with monthly or quarterly return obligations (GSTR-1 and GSTR-3B) even in months with zero sales — missed filings attract late fees per day. Our team files these for clients year-round. If you run your store on MobiFirm's Advance plan (₹1,000/month), GST filing under ₹50 lakh turnover, ITR, trade-licence renewal and professional-tax filings are already included with your online store.

Frequently asked questions

How long does GST registration take?
Typically 3–7 working days after submission with Aadhaar authentication, if documents are clean and no departmental query is raised. With a query, add a few days for the reply and re-verification.
What does GST registration cost?
The government charges no fee for GST registration itself. You pay only the professional fee for preparation, filing and query handling — we quote it transparently before starting, within one business day of your enquiry.
Do I need GST to sell online?
To sell on marketplaces like Amazon or Flipkart, generally yes — they require a GSTIN. On your own website, the normal turnover thresholds apply (₹40 lakh goods / ₹20 lakh services), so many small sellers can legally start on their own store without GST and register when they grow.
Can I register from any state in India?
Yes. The process is fully online — we serve clients across India, from metros to tier-3 towns, with the same process and pricing.
What returns do I file after getting a GSTIN?
GSTR-1 (outward supplies) and GSTR-3B (summary + tax payment), monthly or quarterly under the QRMP scheme. These are due even for zero-sales months. Our team can file them for you, and they are included free with the MobiFirm Advance store plan under ₹50 lakh turnover.
