A sole proprietor’s first difficulty is usually one of identity. The business has a trade name, a shop, perhaps a bank account and a letterhead, but in law it is not a separate person. GST follows that. The registration is taken in the proprietor’s own name and on the proprietor’s own PAN, and every document the portal asks for is read with that in mind.
The common procedure (Part A, the Temporary Reference Number, Part B, Aadhaar, the ARN, processing times, queries and the certificate) is in Applying for GST Registration: the Steps Every Applicant Takes. This guide covers only what is different for a proprietorship.
The PAN is the individual’s
FORM GST REG-01 asks in Part A for the “Permanent Account Number of the Business”, and adds in brackets “Permanent Account Number of Individual in case of Proprietorship concern”. Instruction 1 to the form is more specific: “In case of Proprietorship concern, enter name of proprietor against Legal Name and mention Permanent Account Number of the proprietor.” The portal’s FAQs give the same answer to the question whose PAN to enter: “In case of proprietor, please provide your personal PAN.”
Three consequences follow.
The legal name is the proprietor’s name. The business name goes in the Trade Name field in Part B. The portal’s manual allows up to nine additional trade names.
Turnover is counted on the PAN. Aggregate turnover under section 2(6) covers all supplies of “persons having the same Permanent Account Number”. Every business the individual runs, in every State, counts towards one threshold. The guide on who must register explains the calculation.
One registration per State. Under section 25(2), a person takes “a single registration in a State or Union territory”. A proprietor with two shops, or two different businesses, in one State registers once and declares the second as an additional place of business. Separate registration within the State is available as an option under the proviso to section 25(2) and rule 11, but it is not required.
When the portal displays existing registrations after Part A, it shows every GSTIN held on the individual’s PAN across India. That includes any taken for an earlier business.
The proprietor is the only promoter
The portal’s FAQs state that “in case of a Proprietor, there will be always only one Promoters/Partners/Director”. In the Promoter/Partners tab, the proprietor’s details are entered once: name, date of birth, PAN, Aadhaar number, residential address and photograph. Setting “Also Authorized Signatory” to Yes copies them into the Authorised Signatory tab. The Director Identification Number field is not mandatory for a proprietorship.
The proprietor may appoint someone else, such as an employee or a family member, as authorised signatory. The FAQs confirm that people other than the proprietor can be signatories. Instruction 11 to the form provides that the authorised signatory “shall not be a minor”.
Whose Aadhaar is authenticated
A proprietorship’s applicant is an individual. Section 25(6B), brought into force from 1 April 2020 by Notification No. 18/2020-Central Tax, requires “every individual” to undergo authentication or furnish proof of possession of an Aadhaar number to be eligible for registration.
The portal’s table for a proprietorship concern requires authentication of the proprietor and of the Primary Authorised Signatory where that is a different person. Where the proprietor is the signatory, there is one authentication.
If the portal requires a visit to a GST Suvidha Kendra, the persons selected attend. That visit is for biometric authentication and photographs where Aadhaar is opted and the application is flagged, or for photographs and document verification where Aadhaar is not opted. The FAQs say that where the promoter and the signatory are the same person, that person completes both biometric authentication and document verification.
The document checklist for a proprietorship
| Document | Who provides it | Prescribed by | Notes |
|---|---|---|---|
| Photograph of the proprietor | Proprietor | REG-01 list, item 1(a) | JPEG, up to 100 KB |
| Proof of constitution | Not required | REG-01 list, item 2 | Item 2 names documents for firms, societies, trusts and other bodies, but none for a proprietorship |
| Photograph and proof of appointment of any other authorised signatory | Proprietor and signatory | REG-01 list, items 1 and 5 | The authorisation and acceptance in the form’s format; up to 1 MB |
| Proof of principal place of business | Owner, landlord or consenter | REG-01 list, item 3 | One file, up to 1 MB |
| Bank account proof, when the account is added | Bank | REG-01 list, item 4 | Passbook page, statement or cancelled cheque bearing the name of “the Proprietor or Business entity” |
The proprietor’s PAN and Aadhaar are validated online and are not uploaded as documents. Instruction No. 03/2025-GST directs central tax officers not to seek further constitution documents such as Udyam, MSME, shop-establishment or trade licence certificates. The instruction’s wording is framed around partnership deeds, but the same list of excluded documents is what a proprietor is most often asked for.
Premises: the most common query
Proprietorships are frequently run from premises the proprietor does not own: a family home, a parent’s shop, or a rented room without a written lease. The prescribed documents in item 3 of the REG-01 list cover each case:
- Owned by the proprietor: a latest property tax receipt, municipal khata copy or electricity bill.
- Rented or leased: the rent or lease agreement, with one of those documents showing the landlord’s ownership.
- Owned by a spouse, parent or other relative: a consent letter from the owner, with a document showing the owner’s ownership.
- Rented without a written agreement: an affidavit to that effect, with a document showing possession, such as an electricity bill.
Instruction No. 03/2025-GST adds the practice for central officers. A consent letter “in plain paper by the concerned owner”, with the owner’s identity proof and one ownership document, “should suffice”. The affidavit is to be on “non-judicial stamp paper of minimum value” before a magistrate or notary.
The portal’s FAQs deal with one case that recurs among proprietors. Where premises were taken on a pagdi tenancy by a parent who has died, and the landlord will not register a fresh lease, “a bank statement with the business address will suffice”.
Signing: EVC is available
Instruction 4 to FORM GST REG-01 names the proprietor as the person who signs for a proprietorship. Rule 26(2)(a) of the CGST Rules provides that documents of an individual are signed or verified “by the individual himself or where he is absent from India, by some other person duly authorised by him”.
A proprietorship is not among the constitutions for which instruction 7 to the form requires a digital signature certificate. The application may be signed with a DSC, by e-signature or by EVC. E-signature uses an OTP sent to the mobile number registered with UIDAI. The portal’s FAQs note that it fails where that number differs from the one given in the application. EVC uses an OTP sent to the signatory’s mobile and e-mail as registered on the GST portal.
Bank account and other points after grant
Rule 10A requires bank account details within thirty days of grant or before the first GSTR-1, whichever is earlier. The portal’s FAQs on bank accounts state that where a business account is not yet open, the applicant “can add your personal bank account and update it once your business bank account is open”. For a proprietor, the account is in any case in the proprietor’s name.
Two events later in a proprietorship’s life are handled differently because the business is not a separate person:
- Death of the proprietor. The registration does not pass to the heir. REG-01 lists “Death of the proprietor (if the successor is not a registered entity)” as a reason to obtain registration. The portal also has a separate cancellation route for a legal heir, covered in the guide on cancelling a registration.
- Conversion to a firm or company. Rule 19(1) provides that where “a change in the constitution of any business results in the change of the Permanent Account Number”, the person “shall apply for fresh registration in FORM GST REG-01”. A firm or company has its own PAN, so the new entity registers afresh. The guide on amending a registration explains which changes can be made by amendment and which cannot.
The procedure for a proprietorship, in order
- Enter the proprietor’s own PAN and name in Part A, with the Primary Authorised Signatory’s mobile and e-mail.
- In Part B, enter the business name as trade name; add any second business in the State as an additional place of business.
- Enter the proprietor as the sole promoter, with photograph; add any other authorised signatory with the authorisation and acceptance letter.
- Upload proof of the principal place of business, with a consent letter, rent agreement or affidavit as the premises require.
- Complete Aadhaar authentication for the proprietor, and for the signatory if different, or attend a GST Suvidha Kendra if the portal requires it.
- Sign with EVC, e-signature or DSC.
- After grant, add a bank account within thirty days or before the first GSTR-1, and display the certificate and GSTIN.
The next guide in this set covers partnership firms and limited liability partnerships, where the partners and the authorised signatory are no longer the same person by default.
