GST registration for founders across India — not just a Delhi form
GST registration is how your business gets a GSTIN and the legal right to issue tax invoices, collect GST and claim eligible Input Tax Credit. For sellers in Delhi NCR, Mumbai, Bengaluru, Hyderabad, Pune or anywhere else in India, the filing is digital. The hard part is a file that gets approved without a query loop.
In 2026, officers are stricter on address proof, Aadhaar authentication, HSN/SAC mapping and physical verification in selected cases. A spelling mismatch between your rent agreement and electricity bill is enough to stall GSTIN — especially in Delhi.
This page explains who must register, which GST type fits, which documents matter, what the journey involves, and when professional filing protects your marketplace or client go-live. It is not a click-by-click GST portal tutorial. Wrong category and weak premises papers delay more applications than “not knowing the steps.”
Who must take GST registration?
Thresholds are a starting point. Many businesses must register even below ₹20 lakh / ₹40 lakh.
- Turnover exceeds ₹40 lakhs (goods) or ₹20 lakhs (services) — confirm your current notified limit
- Interstate supply of goods (and many service cases — check your model)
- Selling on Amazon, Flipkart, Meesho or other e-commerce platforms
- E-commerce operators
- Casual taxable persons operating temporarily in a state
- Non-resident taxable persons
- Cases where reverse charge / ISD / notified compulsory categories apply
- Agents and distributors of registered suppliers where registration is required
Penalty for not registering when required
Often 10% of tax due — minimum ₹10,000. Higher consequences where evasion is involved, plus interest and notices.
Types of GST registration
Regular GST
Default for growing businesses. Full ITC on eligible purchases. Monthly or quarterly returns based on eligibility.
Composition scheme
Simpler tax for some small eligible businesses. Lower rates, but no ITC and important restrictions — not for every e-commerce or interstate model.
Casual taxable person
Temporary operations such as exhibitions. Limited validity and advance tax rules apply.
Non-resident taxable person
Foreign suppliers without a fixed place of business in India.
ISD registration
For organisations distributing common ITC across branches.
Why GSTIN matters for Indian businesses
GST is not only a legal checkbox. It unlocks invoices, credit, marketplaces and interstate scale.
Legal invoices and credibility
Issue tax invoices corporate buyers can book. Unregistered vendors get filtered out in onboarding.
Input Tax Credit
Offset eligible GST paid on rent, purchases, software and professional fees against output tax.
Marketplace access
Amazon, Flipkart, Meesho and many B2B portals expect GSTIN before you scale listings.
Interstate supply
Sell beyond your home state with a compliant GSTIN instead of improvised workarounds.
Tenders and loans
GST status often appears in vendor empanelment, banking and due diligence packs.
Voluntary registration
Below threshold, many consultants still register to work with GST clients and claim ITC.
Documents required for GST registration
Exact papers vary by proprietorship, partnership, LLP or company. Address proof is where most Delhi files get stuck.
Common KYC & bank
- PAN of proprietor / firm / company
- Aadhaar of proprietor / authorised signatory / directors
- Passport-size photograph
- Cancelled cheque, passbook or bank statement
- Active mobile and email for OTP
- Constitution proof — deed / COI — where applicable
- Board resolution or authority letter for companies / LLPs
- DSC where the portal requires it for the entity
Principal place of business
- Latest electricity bill — preferably not older than 2 months
- Owned premises: property tax / ownership paper + utility bill
- Rented: rent/lease deed + landlord bill + NOC
- Shared / home / family property: consent letter + owner proof
- Spellings identical across bill, agreement, NOC and application
- Additional place of business papers if you declare more than one site

What the GST registration journey involves
High-level stages only — not a REG-01 click manual. Approval quality and speed matter more than knowing every portal tab.

Document and premises readiness check
Application preparation (business, HSN/SAC, bank, signatory)
Authentication / e-KYC as required for the profile
ARN after submission
Department review, query or verification

Invoice + return setup after approval
Where DIY applications usually break
- Address mismatch across rent deed, electricity bill and form
- Unclear rent papers or missing landlord NOC
- Wrong or vague HSN/SAC and business activity
- Unauthorised signatory for company / LLP
- Poor scans or name mismatch on bank proof
- Late or incomplete reply to a portal query
- Premises not actually usable if physical check happens
What Comtax handles end-to-end

- Registration-type and activity mapping guidance
- Professional filing coordination on the GST portal
- Follow-up through ARN until GSTIN allotment

GST for common business models
Same law nationwide. Pressure points change by how you sell.
Amazon / Flipkart / Meesho sellers
Pickup address papers and product HSN must be clean before catalogue go-live.
Freelancers and consultants
Service threshold is often hit faster than expected. Voluntary GST helps corporate billing and ITC.
Traders and wholesalers
Interstate movement and B2B credit chains make GSTIN essential once you scale.
Restaurants and cloud kitchens
Pair GST planning with FSSAI. Wrong SAC and composition eligibility are common mistakes.
Private Limited / LLP startups
Many take GSTIN soon after COI for invoices, setup ITC and enterprise onboarding.
Delhi NCR local operators
Rented and home offices need a tight NOC chain. Our Paschim Vihar desk reviews that before filing.
After you get GSTIN
A GST number without return discipline creates late fees and cancellation risk. Set this up in the first week.
- Display GSTIN on invoices and premises as required
- Use a compliant tax invoice format
- Confirm monthly vs quarterly return frequency on the portal
- Track GSTR-1 and GSTR-3B due dates
- Reconcile outward supplies and ITC regularly
- Enable e-invoice / e-way bill if your category requires it
- Store certificate and credentials securely
- Update GSTIN with banks, marketplaces and major customers
Typical monthly rhythm
Monthly filers commonly file GSTR-1 around the 11th and GSTR-3B around the 20th of the next month. Quarterly schemes follow their own calendar — confirm yours on the portal.
Comtax offers GST return filing support from ₹799/month so Delhi NCR and pan-India clients do not miss deadlines after registration.

Frequently asked questions
GST registration in India and Delhi NCR — timeline, cost, documents and marketplace needs.
How long does GST registration take in India?
Clean applications with complete documents often finish in about 3–7 working days. Address mismatches, authentication issues or department queries can take longer.
What is the cost of GST registration?
Fees start from ₹1,499. Government registration fee for a standard GST application is nil. Extra costs apply only if you need DSC, agreement registration or query handling on a complex file.
Is GST mandatory below the turnover limit?
Not always. It becomes mandatory regardless of turnover for many e-commerce sellers, interstate supplies and some other notified cases. Voluntary registration is allowed if you need ITC or corporate clients.
Can I get GST registration from any city in India?
Yes. GST filing is digital. Founders across India can complete it with proper KYC and principal place of business proof. Delhi NCR clients can also visit our Paschim Vihar office.
Can I use a home or rented address for GST?
Yes, if the address proof, rent/NOC chain and application details match. Weak premises papers are the most common Delhi query reason.
Do Amazon, Flipkart or Meesho sellers need GST?
In most seller models, GSTIN is required or practically unavoidable for onboarding and tax invoices. Plan GST before you wait on catalogue activation.
What happens after GSTIN is issued?
You must issue compliant invoices and file returns on the assigned frequency. Missing GSTR-1 / GSTR-3B creates late fees and notice risk. Registration is the start of compliance, not the end.
Regular GST or composition scheme?
Regular GST suits growing and B2B businesses that need ITC. Composition is simpler but restrictive. Do not pick it only because the rate looks lower.
What if my GST application is rejected?
Read the reason, correct documents or details, and file carefully. Repeat mistakes on the same address create more friction. We handle query replies and re-filing support.
Do companies need a DSC for GST registration?
Companies and some signatory workflows commonly need DSC. Many proprietorships proceed with Aadhaar authentication, subject to the portal requirement for that case.
