GST registration limits for 2026

Registration becomes mandatory once your aggregate turnover — the PAN-wide, all-India total of taxable, exempt and export supplies — crosses the threshold for your category. The limits in Uttar Pradesh and Delhi (normal category states) are:

📦
₹40 LakhGoods

Suppliers exclusively dealing in goods within normal category states, including UP and Delhi.

🛠️
₹20 LakhServices

Service providers — consultants, freelancers, agencies, professionals — in normal category states.

🏔️
₹20L / ₹10LSpecial States

Reduced thresholds for goods and services respectively in special category states (north-eastern and hill states).

⚠️ Common trap: the threshold is tested on your all-India PAN-level turnover — not per state, not per branch, and including exempt supplies and exports. Many businesses in NCR cross the limit without realising because they count only taxable local sales.

Who must register regardless of turnover

For certain categories, the threshold doesn't apply at all — registration is compulsory from the very first rupee:

🚚 Inter-state suppliers of goods — selling from Ghaziabad to Delhi counts; state lines trigger registration.
🛒 E-commerce sellers — selling taxable goods on Amazon, Flipkart or Meesho requires a GSTIN, with narrow notified exceptions.
🌐 E-commerce operators — platforms collecting payments for suppliers must register and collect TCS.
Casual taxable persons — exhibition stalls, trade-fair sellers and seasonal businesses operating in a state where they have no fixed place.
✈️ Non-resident taxable persons — foreign businesses making taxable supplies in India.
🔄 Reverse charge recipients — anyone liable to pay tax under RCM on notified supplies.
🏢 Input Service Distributors — head offices distributing input credit to branches.
📋 TDS/TCS deductors & agents — government deductors and agents supplying on behalf of principals.

The registration process, step by step

GST registration is fully online through the GST portal. Here is the exact sequence we follow for every client:

1

Generate TRN — Part A of REG-01

Enter PAN, mobile and email on the GST portal. Both are verified by OTP and a Temporary Reference Number (TRN) is issued instantly.

~15 minutes
2

Complete Part B — business details

Using the TRN, fill in trade name, constitution, principal place of business, additional places, goods/services with HSN or SAC codes, bank details and authorised signatory.

The accuracy-critical step
3

Upload documents & Aadhaar authentication

Upload address proof, photographs, constitution documents and bank proof. Complete Aadhaar e-KYC of the proprietor or authorised signatory — it dramatically speeds approval.

Aadhaar = faster approval
4

Submit with EVC or DSC — receive ARN

Verify and submit the application. An Application Reference Number (ARN) is generated for tracking. Companies and LLPs sign with DSC; others can use EVC.

Instant ARN
5

Officer review & clarifications, if any

The department may raise a query in form REG-03 — typically about address proof. A reply in REG-04 must be filed within 7 working days. Clean documentation usually avoids this stage entirely.

Where most DIY applications get stuck
6

GSTIN allotted — certificate in REG-06

On approval you receive your 15-digit GSTIN and registration certificate. Display it at your premises, print GSTIN on invoices, and begin filing returns from the effective date.

~7 working days with Aadhaar auth

Documents checklist

Keep these ready before starting — clean documents are the difference between 7-day approval and a month of clarifications:

🪪PAN CardOf the proprietor, firm, LLP or company — GSTIN is built on it.
🆔Aadhaar CardOf proprietor / partners / directors, for e-KYC authentication.
📸PhotographPassport-size photo of proprietor or authorised signatory.
🏠Address proof of premisesElectricity bill, property tax receipt or registry — recent and legible.
📜Rent agreement / NOCIf premises are rented or owned by a relative — consent letter required.
🏦Bank proofCancelled cheque or bank statement showing name, account and IFSC.
🤝Constitution documentsPartnership deed, LLP agreement or certificate of incorporation, as applicable.
✍️AuthorisationBoard resolution or authorisation letter for the signatory, for entities.
🔏DSCDigital signature — mandatory for companies and LLPs at submission.

What GST registration costs

Government fee:

₹0 — Completely Free

The GST portal charges nothing for registration. What you may choose to invest in is professional handling — correct category and scheme selection, HSN/SAC mapping, clean documentation and query handling, so the registration is right from day one.

  • Professional fees (market estimate) ₹1,500–5,000
  • DSC for company/LLP (if not held) ₹800–2,000
  • Composition scheme opt-in Usually included
  • LUT filing for exporters ₹500–1,500
⚠️ Disclaimer: professional charges above are approximate market estimates for general guidance, not a quotation. Actual fees depend on business constitution, number of places of business and the scope engaged. Contact us for an exact written estimate.

Benefits of GST registration

Registration is not just a legal obligation — for growing businesses across NCR, it unlocks real commercial advantages:

💰
Input Tax Credit

Recover the GST paid on purchases, rent, services and capital goods — directly reducing your effective costs.

🗺️
Sell anywhere in India

Inter-state sales open up legally — supply from Ghaziabad to clients in Mumbai, Bengaluru or anywhere without restriction.

🛒
E-commerce access

A GSTIN is the entry ticket to Amazon, Flipkart, Meesho and quick-commerce platforms.

🏢
Corporate clients

Large buyers prefer registered vendors so they can claim credit — registration directly wins you B2B business.

🌍
Zero-rated exports

Export goods or services without tax under LUT, and claim refunds of input credit — vital for freelancers serving foreign clients.

🏦
Loans & credibility

GST returns are accepted as income proof by banks — strengthening loan, overdraft and tender applications.

Returns you file after registration

Registration is the beginning, not the end — these are the ongoing filings every registered business must plan for:

ReturnWho files itWhat it coversFrequency
GSTR-1Regular taxpayersDetails of all outward supplies (sales) with invoicesMonthly, or quarterly under QRMP
GSTR-3BRegular taxpayersSummary return — tax liability, ITC claimed, tax paidMonthly, or quarterly under QRMP

GST registration — frequently asked questions

The questions business owners across Hapur, Ghaziabad, Noida and Delhi ask us most:

1. What is the GST registration limit for 2026?
For goods suppliers, ₹40 lakh aggregate annual turnover in normal category states including UP and Delhi (₹20 lakh in special category states). For service providers, ₹20 lakh (₹10 lakh in special category states). Several categories must register irrespective of turnover.
2. Is GST registration free?
Yes — the government charges no fee on the GST portal. Professional assistance, if engaged, typically costs ₹1,500–5,000 as a market estimate, covering documentation, correct scheme selection and query handling.
3. How long does approval take?
Around 7 working days with successful Aadhaar authentication. Without it, or where the officer orders physical verification of premises, the process can stretch to 30 days.
4. What documents do I need?
PAN, Aadhaar, photograph, premises address proof (electricity bill / property document), rent agreement or NOC if applicable, bank proof (cancelled cheque or statement), and constitution documents such as a partnership deed or incorporation certificate for entities.
5. Who must register compulsorily, regardless of turnover?
Inter-state goods suppliers, e-commerce sellers and operators, casual and non-resident taxable persons, reverse-charge recipients, input service distributors, agents, and TDS/TCS deductors — for all of these, the threshold exemption is unavailable.
6. What is the composition scheme and who can opt for it?
A simplified scheme for small businesses with turnover up to ₹1.5 crore (₹75 lakh in special states) — pay a low flat rate of tax, file quarterly CMP-08 and one annual return. Service providers have a parallel option up to ₹50 lakh. The trade-offs: you cannot collect tax from customers, claim ITC, or make inter-state outward supplies.
7. Can I register voluntarily below the threshold?
Yes, and it's often smart — voluntary registration unlocks input credit, inter-state sales, marketplace selling and stronger credibility with corporate clients. Note that all return-filing obligations apply once registered.
8. What exactly is GSTIN?
Your 15-character Goods and Services Tax Identification Number: two digits of state code, ten characters of PAN, an entity code, a default letter and a check digit. It must appear on every invoice you issue.
9. I have offices in Noida and Delhi — one registration or two?
Two. Registration is state-wise, so a place of business in Uttar Pradesh and another in Delhi require separate GSTINs under the same PAN, each with its own returns.
10. Which returns will I have to file?
Regular taxpayers file GSTR-1 and GSTR-3B (monthly, or quarterly under QRMP) and annual GSTR-9 where applicable. Composition dealers file quarterly CMP-08 and annual GSTR-4.
11. What is the QRMP scheme?
Quarterly Return Monthly Payment — available up to ₹5 crore turnover. You file GSTR-1 and GSTR-3B quarterly while paying tax monthly via a simple challan, reducing annual filings from 24 to 8.
12. What if I don't register even though I'm liable?
A penalty of 10% of the tax due (minimum ₹10,000), and up to 100% of tax where evasion is deliberate — plus payment of the entire back tax with interest. The department increasingly identifies unregistered businesses through e-commerce, bank and income-tax data matching.
13. What are late fees for GST returns?
₹50 per day per return (₹25 CGST + ₹25 SGST), reduced to ₹20 per day for nil returns, with turnover-linked caps — plus 18% per annum interest on any unpaid tax.
14. Can I sell on Amazon or Flipkart without GST?
For taxable goods — no, a GSTIN is mandatory regardless of turnover. Narrow exemptions exist for certain intra-state service providers and notified small intra-state goods sellers, but most marketplace sellers need registration before listing.
15. Do freelancers need GST registration?
Yes, once turnover crosses ₹20 lakh — and export income from foreign clients counts toward that figure. Registered freelancers can file an LUT to keep their service exports zero-rated and claim refunds of input credit.
16. What is an LUT and do I need one?
A Letter of Undertaking (form RFD-11, filed online annually) lets you export goods or services without paying IGST. Essential for exporters and freelancers with overseas clients — without it, you'd pay tax upfront and chase refunds.
17. Can I use my home address for registration?
Yes — a residential address can be your principal place of business, which suits freelancers, consultants and online sellers. You'll need address proof and, if the property is rented or in a family member's name, a rent agreement or consent letter.
18. What is aggregate turnover?
The all-India, PAN-level total of taxable supplies, exempt supplies, exports and inter-state supplies — excluding GST itself and inward reverse-charge supplies. The registration threshold is tested against this combined figure, not your sales in one state.
19. Can GST registration be cancelled later?
Yes — voluntarily, if the business closes or falls below the threshold, or by the department for sustained non-filing. After cancellation, a final return (GSTR-10) is due within three months, and any ITC on stock may need reversal.
20. Why hire a CA instead of registering myself?
The portal is free, but the decisions inside it aren't trivial: regular vs composition, QRMP or monthly, correct HSN/SAC codes, the right additional places of business, and clean replies to any REG-03 query. Errors here translate into wrong tax rates, blocked credit or notices months later.
