GST registration fees in India: what the government charges (nothing), what you actually pay, and what it costs to get it wrong

The government fee for GST registration in India is nil. Nothing to file FORM GST REG-01, nothing to answer a query, nothing for the registration certificate in FORM GST REG-06, nothing to amend it later. If a website shows you a “government fee” line item, that is their fee with a different label.

That fact also creates the confusion. Because the fee is zero, founders assume the registration is free — then meet a bill for a digital signature, a rent agreement, stamp paper or a consultant, and cannot tell which of those they were obliged to pay. Some are compulsory, most are not, and one of them (the address) is usually the biggest number on the page.

This guide separates the two: every real cost and who has to pay it, then the far larger cost of registering late or not at all. Everything here is as of September 2026, with the section, rule or form named so you can check it.

Is there a government fee for GST registration?

No. GST registration is free of government charge for every category of applicant — proprietor, partnership, company, LLP, trust, society, e-commerce seller, casual taxable person. The application is made under Rule 8 in FORM GST REG-01, and the portal takes no payment at any stage. Nor does anything around it:

Who charges what: the honest cost list

Every cost that can appear on a GST registration, who charges it, and whether you have to pay it.

Read down the third column and the picture is clear. A proprietor who owns her shop and files the form herself pays zero from start to GSTIN. A company registering in a state where it has no premises pays for a DSC, an address and stamp duty — and still nothing to the government.

Do you need a Digital Signature Certificate?

Only if you are a company or an LLP. Rule 26 of the CGST Rules requires those two to sign GST applications and returns with a Digital Signature Certificate. Every other applicant — proprietorships, partnership firms, HUFs, trusts, societies — may verify with an e-signature or an electronic verification code, an OTP sent to the Aadhaar-linked mobile number. That costs nothing.

Where a DSC is needed it is a Class 3 certificate from a licensed certifying authority, issued to the authorised signatory as an individual and stored on a USB token. Market prices run roughly ₹1,000–2,500 for two years, indicative only — resellers price differently, and a token, GST on the fee and video-KYC handling can sit on top.

You probably already have one: if you incorporated a company or an LLP, a director or designated partner bought a Class 3 DSC for the MCA filing, and the same certificate signs the GST application. Check its expiry date before you start. The DSC belongs to a person, not to the business, and that person must be the authorised signatory on the portal with the same PAN as on the certificate — a mismatch produces a signature failure that looks technical and is actually a data error.

Professional fees: what a consultant charges and what you are buying

Nothing in the CGST Act or Rules requires you to use a professional. FORM GST REG-01 is a public form on a public portal, and Part A takes only your PAN, mobile number and email to generate a Temporary Reference Number. Plenty of proprietors and small partnerships file their own and never speak to a consultant.

Professional fees, where charged, are unregulated and vary widely — a few hundred to a few thousand rupees is the honest range, and anyone quoting a firm national figure is quoting their own price list. What moves it is the entity type, the city, and above all what is included after submission. Four questions before you agree a fee:

• Does the fee cover a query? If the officer issues FORM GST REG-03, the reply in REG-04 is due within seven working days. A quote covering only “filing” often stops when the ARN is generated — exactly when the work starts.
• Who owns the portal login? Insist that the email and mobile registered on the portal are yours. Recovering a GST login from a former consultant is a slow, avoidable problem.
• Is the address included or extra? Many “GST registration packages” quietly assume you have premises and a landlord willing to sign an NOC.

The cost of a business address, if you do not have one

For most first-time applicants this is the largest real number, because registration is state-wise under Section 25 and needs a place of business in that state. REG-01 asks for the principal place of business and the nature of possession; for rented or shared premises that means a rent or leave-and-licence agreement plus one document proving the owner’s ownership, or a consent letter (NOC) with the same proof.

As one concrete example, SimplySetup’s prices — billed annually, plus 18% GST — are ₹399 a month for a Business Address (address, mail handling and name board, but no rent agreement or NOC), ₹799 a month for the GST Registration package (which adds the rent agreement, owner NOC and utility bill kit, plus filing support), and ₹899 a month for the Company Registration package. The ₹799 plan is ₹9,588 for the year before GST. Other providers price differently; what matters is the structure, not the number.

Note the gap between the first two plans. An address-only plan does not carry the possession documents REG-01 asks for; without an agreement and an owner’s NOC it cannot be used to register for GST, whatever the listing says. Addresses are listed city by city and by state with its GST code.

Stamp duty and notarisation on the agreement

Stamp duty is a state subject. Each state’s stamp act sets its own rate and method for a rent or leave-and-licence agreement — some a percentage of the rent for the term, some a slab, some adding a notional amount on the deposit. Registration and notary charges are separate again. So we quote no number: ask for the figure for your state and term before signing, because a national figure would be wrong everywhere.

Two structural rules explain why agreements look the way they do:

• Eleven months is not superstition. Section 17(1)(d) of the Registration Act, 1908 requires a lease from year to year, or for a term over one year, to be registered. A shorter term avoids that, which is why so many agreements run eleven months.
• Maharashtra is different. Section 55 of the Maharashtra Rent Control Act, 1999 requires every leave and licence agreement to be written and registered, and puts that duty on the licensor. Stamp duty is 0.25% of the total licence fee for the term plus a notional amount on the refundable deposit (Article 36A, Maharashtra Stamp Act), with a registration fee of ₹1,000 in municipal corporation areas and ₹500 elsewhere. The leave and licence guide covers it.

Where a provider quotes an all-in package, ask whether stamp duty and notarisation are inside it or billed at actuals. Both are legitimate; only one is a surprise. The NOC and rent agreement guide explains what each document has to say.

Advance tax for casual and non-resident taxable persons

This is the only money a registration sends to the government up front, and it reaches two narrow categories. A casual taxable person occasionally supplies goods or services in a state where they have no fixed place of business — an exhibitor at a trade fair, a contractor on a short project. A non-resident taxable person supplies in India without a fixed place of business here. Both must register regardless of turnover under Section 24, and both must deposit tax in advance under Section 27 equal to the liability they estimate for the period applied for.

• The registration is valid 90 days, extendable by a further 90 on a fresh estimate and deposit.
• The deposit sits in the electronic cash ledger and is set off against actual liability; any excess is refundable once returns are filed.
• You still need an address in the state — a casual registration does not exempt you from declaring a place of business.

For a two-week exhibition a casual registration usually beats a year of any address plan. For a seller whose stock will sit in a state warehouse for twelve months it does not — that is a normal registration, and the VPOB and APOB guide walks through it.

DIY vs a consultant vs a virtual office package

Three routes to a GSTIN, compared on what each costs and where each breaks.

All three produce the same certificate for the same zero government fee. Choose on the failure mode: who handles the seven-working-day query window, and whether there is a real, signposted premises behind the address.

What it costs to register late — or not at all

Now the number that dwarfs everything above. Section 122(1)(xi) of the CGST Act makes a person liable to register who fails to do so liable to a penalty of ₹10,000 or the tax evaded, whichever is higher. That “whichever is higher” is the sting: the penalty tracks your turnover, not a fixed schedule.

Three other things happen at the same time, and together they cost more than the penalty:

1. The tax is still due. Being unregistered does not remove the liability on supplies made once you crossed the threshold. It is recoverable with interest.
2. You cannot collect it from customers. Going back to buyers months later for GST on completed sales almost never works, so the tax comes out of your own margin.
3. You lose the input credit for that period. Credit is tracked per GSTIN, and GST paid on purchases while you were unregistered is generally not recoverable.

Timing matters too. Under Rule 10, apply within 30 days of becoming liable and the registration takes effect from the date you became liable, regularising the earlier period cleanly. Apply later and it takes effect from the date of grant, leaving the gap as unregistered supply the department can assess.

A worked example

A Karnataka trader selling goods only crosses the ₹40 lakh threshold on 10 September, so she should apply by 10 October. She applies the following March instead, having supplied ₹12 lakh of goods taxable at 18% in between.

The tax cannot be recovered from her customers, and the input credit on those months’ purchases is gone. Registering on time would have cost nil in government fees and a four-figure sum for a compliant address. The delay, not the registration, is what costs money.

Late fees for returns after you are registered

Once you hold a GSTIN a second cost clock starts: every return is due whether or not you traded. Section 47 sets the late fee for GSTR-3B and GSTR-1 at ₹50 a day (₹25 CGST plus ₹25 SGST), or ₹20 a day for a nil return, subject to caps by turnover.

Separately, Section 50 charges interest at 18% a year on tax paid late. Late fees run per return and per form, so one missed month can attract a fee on both GSTR-1 and GSTR-3B.

The caps make dormant registrations look cheap, and they are not. A registration taken “just in case” and then ignored accrues a nil-return late fee on every period, on two forms, and the portal blocks a later return until the earlier one is filed. Persistent non-filing is also a ground for cancellation.

When you do not need to register at all

The cheapest GST registration is the one you did not need. Section 22 sets the turnover thresholds:

• ₹20 lakh of aggregate turnover in a financial year for most states, and ₹10 lakh in Manipur, Mizoram, Nagaland and Tripura.
• ₹40 lakh for suppliers of goods only in most states, under Notification 10/2019-Central Tax — a few states kept the ₹20 lakh limit, so check yours. This higher limit never applies to services.

Section 24 then overrides the threshold for certain persons, who register from the first rupee: inter-state supply of goods, casual taxable persons, persons liable under reverse charge, non-resident taxable persons, e-commerce operators, persons selling goods through an e-commerce operator, input service distributors, agents, TDS deductors and OIDAR providers.

Remember that aggregate turnover is PAN-level and all-India, while registration is state-wise: one per state per PAN under Section 25.

Is registering voluntarily worth paying for?

Below the threshold you can still register voluntarily. It is free to obtain and not free to keep, so weigh it properly.

Reasons it usually pays for itself:

• Input tax credit. GST on taxable inputs — stock, software subscriptions, professional services, coworking fees at 18% — is a real cost until you register. Registration turns it into credit.
• Marketplaces. Selling goods through an e-commerce operator is compulsory under Section 24 anyway, so for most sellers this is not a choice.
• B2B customers. Registered buyers want an invoice they can claim credit on. Without a GSTIN your price is effectively higher by the tax they cannot recover, and some procurement systems will not onboard an unregistered vendor.
• Credibility and banking. A GST certificate with a commercial address is standard evidence for current-account KYC and vendor onboarding.

Reasons to wait: you sell mainly to consumers, who cannot use the credit, so adding 18% just makes you dearer; your inputs are largely untaxed, so there is little credit to gain; or you are not ready for returns, and Section 47 late fees start from the first missed period, including nil ones.

The cost profile is identical either way: nil to the government, a DSC only for companies and LLPs, and an address if you do not have one. The GST registration overview sets out the process end to end.

What to do next

Start by checking whether you are liable at all: run your aggregate turnover for the year to date, and read Section 24 to see whether the threshold even applies to you. If you are liable, note the date you crossed it and apply within 30 days, so Rule 10 dates the registration back to that day rather than to the grant. Then gather the documents on the REG-01 list — and only those — and buy a DSC only if you are a company or an LLP. If the gap is the address, check whether an owner NOC on premises you already occupy will do the job before you pay anyone. If it will not, tell SimplySetup the state and what you sell, and we will send back the document list, the timeline and a fixed price.
