CBIC GST Registration Guidelines: Circular 257/2026

In short

CBIC Circular No. 257/03/2026-GST, dated 26 October 2026, tells applicants exactly what to file with Form GST REG-01 and limits what tax officers may ask for. It fixes the proof of premises for owned, rented, family-owned, inherited and co-working premises, gives standard formats for the consent letter, rent undertaking and inheritance affidavit, and bars officers from asking for things like a Udyam certificate or a local residential address, or from judging whether a home is fit for business.

CBIC GST Registration Guidelines: Circular 257/2026

On 26 October 2026 the Central Board of Indirect Taxes and Customs (CBIC) issued Circular No. 257/03/2026-GST, "Guidelines for the handling applications for GST registration". It is a 38-page document with three parts that matter to anyone applying for a GSTIN: guidelines on filling Form GST REG-01, 51 frequently asked questions (Annexure-I), and checklists of documents by type of business and type of premises (Annexures II and III), followed by ready formats for an affidavit, an undertaking and a consent letter (Annexures IV to VI).

The circular does not change the GST Act or Rules. What it does is write down, in one place, what a complete application looks like and what an officer may and may not ask for. CBIC says its own analysis found that most queries and rejections come from missing, inconsistent or illegible documents, mainly about the applicant's identity, the principal place of business, the constitution of the business and the authorised signatory. Officers already had processing instructions (Instruction No. 03/2025-GST of 17 April 2025); this circular gives applicants the matching guidance.

What are the main changes in Circular 257/2026?

In short, the circular does five things:

  1. Fixes the document list. Officers must stick to the prescribed documents and must not ask for "additional or unnecessary papers". Annexures II and III are now the reference list.
  2. Standardises premises proof. It sets out what to upload for owned, rented (with or without a registered agreement, or with no agreement at all), family-owned, jointly owned, inherited, co-working and SEZ premises.
  3. Gives formats. An affidavit for inherited property (Annexure-IV), an undertaking where there is no rent agreement (Annexure-V), and a consent letter for premises owned by a family member or someone else (Annexure-VI).
  4. Limits officer queries. A clarification notice in Form GST REG-03 may only be raised for an incomplete or illegible document, an address that does not match the proof, or a vague or incomplete address. The circular lists queries officers should not raise at all.
  5. Restates the timelines and the deemed approval rule, and tells applicants where to complain about delays or unwarranted queries.

Which form do I use to apply for GST registration?

Most businesses apply in Form GST REG-01 on gst.gov.in under Services > Registration > New Registration. The circular lists the other forms:

ApplicantForm
Normal taxpayer, Input Service Distributor, casual taxable personGST REG-01
Tax deductor (section 51) or e-commerce tax collector (section 52)GST REG-07
Non-resident taxable personGST REG-09
OIDAR services or online money gaming supplied from outside IndiaGST REG-10
UN bodies, embassies and other notified persons (Unique ID)GST REG-13

REG-01 has two parts. Part A generates a Temporary Reference Number (TRN) and asks for PAN, legal name, state and district, email and mobile. Part B is the full application.

What should go in Part A of Form GST REG-01?

The legal name must be exactly as on the PAN, and for a company, as on the Certificate of Incorporation. For a proprietorship, the legal name is the proprietor's own name, not the shop's trade name. The circular also advises using the email address and mobile number already linked to the PAN, and choosing the correct state and district of the principal place of business at this stage.

What details does Part B need?

Part B is where most mistakes happen. The circular's guidance, section by section:

  • Constitution of business. Choose the right one (proprietorship, partnership, HUF, private or public company, LLP, trust, AOP and so on) and upload the partnership deed, registration certificate or other proof of constitution where the checklist asks for it.
  • Options. Tick "Yes" clearly if you want the composition scheme (and pick the right category), casual taxable person status, or the simplified registration under rule 14A. For an SEZ unit or developer, give the approval order number, date, validity and approving authority, and upload the order.
  • Reason for registration. Pick the reason that actually applies (crossing the threshold, voluntary, inter-state supply, reverse charge under section 9(3) or 9(4), change in constitution and so on). CBIC says the reason should be consistent with the constitution and other details, and it can matter for the category of registration and even at cancellation.
  • Promoters and partners. Proprietor; managing partner and all partners of a firm or LLP; Karta of an HUF; managing director and all whole-time directors of a company; managing committee members of an association; all trustees of a trust. DIN is mandatory for company directors and LLP designated partners, and the portal validates DIN and CIN online against MCA records.
  • Authorised signatories. Up to ten, each with the same personal details and a photograph, plus an authorisation letter from the proprietor, partners, board, trust or committee. The primary authorised signatory signs the application digitally. CBIC suggests adding at least two, so the application is not stuck if one person is unavailable for e-sign, DSC or Aadhaar verification.
  • Authorised representative. Optional. If it is a GST Practitioner, give the enrolment ID.
  • Goods and services. List all HSN and SAC codes you supply or plan to supply, or at least the main ones. More can be added later through an amendment in Form GST REG-14.
  • State-specific fields. In Maharashtra, Rajasthan, Odisha, Andhra Pradesh, Assam and Madhya Pradesh, the electricity board and consumer number for the business premises are mandatory.

What photographs are accepted?

Photographs cause more queries than most people expect. The circular says each photograph must:

  • be of the person concerned alone, not cropped from a group photo;
  • show the full front face, in colour, recent, and of reasonable resolution;
  • not be a scan or crop of a PAN card, Aadhaar, driving licence, passport or any other ID.

Uploading the wrong person's photograph can lead to a query or outright rejection. For partnership firms, LLPs and associations, photographs are needed for all partners or committee members, capped at ten where there are more.

How should the business address be written?

The principal place of business (PPoB) is, in CBIC's words, "one of the major reasons" for queries and rejections. The address must identify the specific shop, flat, office or plot, not just a road, colony, village or khasra number. Give the building or plot number, khasra or khata number where relevant, street, locality, city or village, taluka or block, district, the correct PIN code and a landmark. CBIC also asks applicants to drag the map marker on the portal to the exact location so the latitude and longitude are captured.

Then pick the State and Centre jurisdiction that matches the PIN code. A wrong jurisdiction means the application has to be transferred, or the physical verification reassigned, which delays it. The address typed in the form must match the address on the proof you upload, word for word as far as possible.

Unmanned installations such as telecom towers and bank ATMs do not need to be declared as a principal or additional place of business.

What proof of premises does CBIC accept now?

This is the core of the circular. Annexure-III and paragraphs 3.8.2 to 3.8.6 set the documents by type of premises:

PremisesUpload
Owned by the applicantAny one, in the applicant's name: latest property tax receipt, municipal khata, property identification document, latest electricity bill or latest water bill
Rented, registered agreement (or registration is mandatory locally)The registered rent or lease agreement
Rented, agreement not registeredThe rent agreement plus any one ownership document above in the landlord's name. If the electricity or water connection is in the tenant's name, the tenant's latest bill can be given instead of the landlord's document
Rented, no agreement at allUndertaking in the Annexure-V format plus a latest electricity or water bill showing possession by the applicant (see the note below)
Owned by a family member, partner or director (consent)Consent letter in the Annexure-VI format plus any one ownership document in the consenter's name
Inherited, nothing in the applicant's name yetDeath certificate of the ancestor, affidavit in the Annexure-IV format, and any one ownership document in the ancestor's or applicant's name
Co-working spaceMembership agreement showing the allotted desk or cabin, plus the provider's ownership document, or the registered lease between the property owner and the provider
SEZ unit or developerLetter of Approval or Letter of Permission from the Development Commissioner

Every document has to be clear, complete and legible, with the name and full address matching the application. Electricity and water bills should be the latest ones.

Can I declare my parents' house as "own" premises?

No. This is one of the most common errors the circular addresses. If the property is in the name of a parent, spouse, sibling, or one of the partners or directors, the business does not own it. Select "Consent" (or "Rented/Leased" or "Shared", whichever is true) as the nature of premises, and upload the owner's consent letter with one of their ownership documents. Where the property has more than one owner, consent is needed from each of them.

Joint ownership by the applicant is treated differently: a co-owner applying for registration does not need consent or an NOC from the other co-owners. If the utility bills are only in the other co-owner's name, upload a document that shows both owners.

The circular gives the wording for all three, so there is no longer any guesswork about format:

  • Consent letter (Annexure-VI) on plain paper, signed by the owner, with the owner's name, PAN, phone and address, the applicant's name and relationship, and the premises address. It can grant the whole premises or a clearly marked part of it, such as a named cabin or workstation area, which the owner confirms is exclusively for the applicant.
  • Undertaking (Annexure-V) where there is no rent agreement, signed by the applicant. It names the owner, says there is no written agreement, gives the month and year from which the applicant has occupied the premises, and confirms the applicant pays the utilities and is responsible for GST compliance there.
  • Affidavit (Annexure-IV) for inherited property, on non-judicial stamp paper of at least ₹100, attested by a First-Class Judicial Magistrate, Executive Magistrate or Notary. It records the death, the applicant's status as legal heir, lawful possession and responsibility for utilities and taxes.

What can GST officers no longer ask for?

Paragraphs 5.4.1 and 6 of the circular are the part most applicants will welcome. CBIC records that officers have been raising "unwarranted" queries and tells them to stop. Officers should not:

  • ask why the applicant's, managing director's or authorised signatory's home address is in a different city or state;
  • ask for a Udyam (MSME) certificate, which is neither required nor accepted as proof of premises;
  • object that the declared business activity cannot be carried on from the premises;
  • decide whether an electricity connection is domestic or commercial, or question the amount of a bill;
  • treat residential premises as unfit for business;
  • ask for photographs of the applicant or landlord at the premises;
  • seek any document outside the prescribed list, or communicate outside the portal.

Checks on utility bills and property tax receipts are limited to the name and address. For rent agreements, the officer checks validity, the names of both tenant and landlord, and the exact address. Where something is genuinely missing or mismatched, the only route is a notice in Form GST REG-03, which gives the applicant a chance to correct it rather than facing straight rejection.

How long does GST registration take now?

The circular restates the timelines in rules 9, 9A and 14A of the CGST Rules:

SituationTime for a decision
Simplified registration under rule 14A, or applicant picked by the system for electronic grant under rule 9AGranted automatically within 3 working days
Aadhaar authentication opted for and completed7 working days from the application
No Aadhaar authentication, failed authentication, or physical verification ordered30 days, after physical verification of the premises
Reply filed in REG-04 to a queryOfficer decides within 7 working days of the reply

If the officer takes no action within these limits, the registration is deemed approved and the certificate in Form GST REG-06 appears on the portal.

Some applicants who opt for Aadhaar authentication may still be picked, on risk parameters, for biometric authentication, a photograph and verification of original documents at a GST Suvidha Kendra (facilitation centre). Applicants who do not opt for Aadhaar authentication always have to visit one. According to the FAQs, the visit must be completed within 15 days of receiving the TRN, and the application counts as complete only after that verification.

What happens after a REG-03 query?

A query in REG-03 must normally be raised within 7 working days of the application, or within 30 days where physical verification applies. The applicant has 7 working days from receiving it to reply in Form GST REG-04. The officer then has 7 working days to approve the application or, if not satisfied, reject it with recorded reasons in Form GST REG-05.

For physical verification, the officer must give a specific report on whether the premises exists, record the efforts made to locate it if it does not, upload GPS-tagged site photographs, and upload the report in Form GST REG-30 at least five days before the 30-day limit runs out.

All communication is through the GST portal, so check it and your registered email regularly once you apply. Missing the 7-day reply window is one of the easiest ways to lose an application.

What is the simplified registration under rule 14A?

Rule 14A, in force from 1 November 2025, is an optional fast track for small suppliers whose tax charged to registered buyers stays within ₹2.5 lakh a month (IGST, CGST and SGST together). Registration is granted by the system within three working days, with no officer involved. To use it you must apply in REG-01, opt for Aadhaar authentication and choose rule 14A, and you can hold only one rule 14A registration per PAN in a state.

If the business grows past the ₹2.5 lakh limit, you withdraw in Form GST REG-32 after filing all returns due, and at least one return after registration. The circular confirms that the withdrawal is processed like a normal REG-01 application, with the same documents.

What if my registration was suspended or cancelled earlier?

If an earlier registration on the same PAN was suspended under rule 21A(2) or (2A) or cancelled under rule 22, file every pending return for it, including the final return in GSTR-10 where applicable, and clear any outstanding liability before applying again. Our GST registration cancellation page explains the final return.

Where can I complain about a delayed GST registration?

Paragraph 8 of the circular lets an aggrieved applicant complain to the jurisdictional Chief Commissioner of Central Tax or Commissioner of State Tax, on a special email address that each zone or state will notify. The circular asks field offices to publicise it through trade notices, so the address will vary by state; it is not given in the circular itself.

If an application is rejected, the FAQs say a fresh application can be filed after fixing the deficiencies listed in the rejection order.

What should I do before applying?

  • Check that the legal name, PAN, DIN and CIN all match MCA and income tax records.
  • Choose the correct nature of premises. If you do not own it in your own name, it is not "own".
  • Use the latest utility bill, and make sure its address matches the form exactly.
  • Use the CBIC formats for any consent letter, undertaking or affidavit.
  • Write the full address down to the shop or flat number, and set the map pin.
  • Upload proper individual photographs, not ID card scans.
  • Opt for Aadhaar authentication, and add a second authorised signatory.
  • Keep an eye on the portal for 30 days and reply to any REG-03 within 7 working days.

Frequently asked questions

What is CBIC Circular 257/03/2026-GST about?

It is CBIC's guideline for people applying for GST registration, issued on 26 October 2026 under section 168(1) of the CGST Act. It explains how to fill Form GST REG-01, lists the documents for each type of business and premises, gives formats for consent letters and undertakings, restates the processing timelines, and tells officers not to ask for documents outside the prescribed list.

Does the circular change the GST registration rules?

No. It does not amend the CGST Act or Rules. It explains how the existing rules (mainly rules 8, 9, 9A, 10A, 14A and 25 of the CGST Rules) should be applied, so that applicants and officers across states follow one standard list of documents and the same limits on queries.

Can a GST officer ask for a Udyam certificate with my application?

No. The circular names the Udyam certificate as an unwarranted document that officers should not seek, and its FAQs say a Udyam or MSME certificate is neither required for GST registration nor accepted as proof of the place of business.

Can I get GST registration if I live in a different state from my business?

Yes. The circular says you do not need a residential address in the same city, district or state as your place of business, and it lists a query about the applicant's or director's home address being elsewhere as one officers should not raise. Give both addresses accurately in REG-01.

Is a domestic electricity bill accepted as GST address proof?

Yes. Officers are told not to classify the connection as domestic or commercial or to question the bill amount. The check on an electricity or water bill is limited to the name and the address, which must match the application. Use the latest bill.

What documents are needed for GST registration without a rent agreement?

Upload an undertaking in the Annexure-V format of the circular, which names the owner and says since when you have occupied the premises, together with a latest electricity or water bill showing the full address. The body of the circular asks for a bill in the tenant applicant's name, while its Annexure-III table also mentions a document in the owner's name.

Is a notarised rent agreement enough for GST registration?

It depends on whether the agreement has to be registered in your state. If registration of the lease is mandatory there, only a registered agreement is accepted. If it is not, an unregistered rent agreement works, provided you also upload one ownership document in the landlord's name, such as the latest electricity bill or property tax receipt.

Annexure-VI of the circular gives it. It is on plain paper, signed by the owner, and states the owner's name, PAN, contact number and address, the applicant's name and relationship, the premises address, and whether the whole premises or a marked portion such as a cabin is allowed for business. Attach one ownership document in the owner's name.

How do I register for GST on a property inherited from my father?

If nothing is yet in your name, upload the death certificate, an affidavit in the Annexure-IV format on non-judicial stamp paper of at least ₹100 attested by a magistrate or notary, and one ownership document such as a property tax receipt or electricity bill in your father's name or yours.

Can I use a virtual office or co-working desk for GST registration?

A co-working space is accepted if you have a specific allotted desk, cabin or suite. Upload the membership agreement showing that space and its period, plus the provider's ownership document, or the registered lease between the building owner and the provider. A PO box or courier address is not accepted.

No. A co-owner who uses the jointly owned property as the place of business does not need consent or an NOC from the other co-owners. If the bills are only in the other co-owner's name, upload a document that shows the names of both owners.

Can a SEZ unit use the same GSTIN as the company's other office in the state?

No. A SEZ unit or SEZ developer needs a separate GST registration even if the business already has a GSTIN for a place outside the SEZ in the same state. Upload the Letter of Approval or Letter of Permission from the Development Commissioner as proof of the premises.

How many authorised signatories can be added in GST registration?

Up to ten, including the primary authorised signatory. Each needs personal details, a photograph and an authorisation letter from the proprietor, partners, board or committee. CBIC advises at least two, so that the application can be signed and verified if one person is unavailable.

How many days do I have to reply to a GST REG-03 notice?

Seven working days from receiving the notice. The reply is filed in Form GST REG-04 on the portal with the documents asked for. If you do not reply in time, the officer may reject the application in REG-05. After a reply, the officer has seven working days to approve or reject.

What happens if the GST officer does not act on my application in time?

The registration is deemed approved, and the certificate in Form GST REG-06 is made available on the portal automatically. The limits are three working days for rule 14A and rule 9A cases, seven working days with Aadhaar authentication, and thirty days where physical verification applies.

How do I complain about delay in GST registration?

The circular lets you file a grievance with the jurisdictional Chief Commissioner of Central Tax or Commissioner of State Tax, on a special email address each zone or state is to notify, for delays or unwarranted queries. Look for the trade notice issued by your state or CGST zone for the exact address.

Do telecom towers and ATMs need to be added as an additional place of business?

No. The circular clarifies that unmanned installations such as telecom towers and bank ATMs do not have to be declared as a principal or additional place of business in the GST registration application.
