A proprietorship declaration is a signed statement in which you confirm that you alone own and run your business, with no partners or shareholders.
It is a simple letter, not a registration, because no law sets one fixed format for it.
There is no RBI rule that lists this declaration among the documents a bank must collect.
Banks, FSSAI and some platforms ask for it on their own terms, so the wording they want can differ from one asker to the next.
This guide shows who usually asks for one, gives sample text you can copy and fill in, and explains when a plain letter is enough and when an affidavit on stamp paper comes in.
Who asks for a declaration of proprietorship and what they want
A sole proprietorship has no separate legal identity, so an asker sometimes wants a written declaration of proprietorship to confirm nobody else has a stake in the firm.
- Banks opening a current account: Many banks want the proprietor to confirm in writing that the account is for a firm they own alone. Some give their own form, others accept a letter in your words.
- FSSAI food licence or registration: The FoSCoS portal lists a self-declaration for proprietorship as proof of how the business is set up, and it offers its own sample format.
- Clients, platforms and vendors: Some buyers and platforms ask for one at onboarding. If they hand you a form, use it.
Proprietorship declaration format you can copy and fill in
The format below carries the same core details whoever reads it. Replace everything in [square brackets] and delete any line that does not apply to you, such as GST if you are not registered.
Declaration letter on letterhead for any asker
Print this on your business letterhead if you have one, or on plain paper if you do not.

Sole proprietorship declaration for a bank current account
A sole proprietorship declaration for a bank adds the account details and confirms that you alone will operate it.
[Date]
To,
The Branch Manager,
[Bank name], [branch address]
Subject: Declaration of sole proprietorship for opening a current account
I, [your full name], declare that I am the sole proprietor of [firm name], located at [business address]. The firm has no partners or shareholders.
I request you to open a current account in the name of [firm name]. I will be the only person authorised to operate this account and sign on its behalf.
I undertake to inform the bank in writing if the ownership or constitution of the firm changes.
[Signature]
[Your name], Proprietor, [firm name]
Place: [city]
[Firm stamp, if you have one]
Ask the branch before you print it. Many banks already include this wording in their account opening form, in which case you sign their version instead.
Key details to include in a proprietorship declaration
Askers do not share one fixed list, but most declarations carry the same core details. Check each one against your PAN and registrations before you sign.
- Proprietor name: Your full name exactly as it appears on your PAN, so the asker can match it to your ID.
- Business or trade name: The name your firm uses, written the same way as on invoices and registrations.
- Business address: The place you run the business from, plus your residential address if the format asks for it.
- PAN and registrations: Your PAN, and any Udyam number, GSTIN or other registration the firm holds.
- Nature of business: A few plain words on what the firm does, such as software services or food retail.
- Date of start: When the business began trading, if the asker wants it.
- Sole ownership statement: A clear line that you alone own the firm, with no partners or shareholders.
- Signature, date and place: Your signature as proprietor, with the date and city of signing.
- Seal, if any: Your firm stamp next to the signature, if you have one.
When a proprietorship affidavit needs stamp paper or a notary
A declaration and an affidavit say similar things, but an affidavit carries more legal weight. You sign it on non-judicial stamp paper and swear it before a notary or oath commissioner, who stamps and signs it as well.
| Point | Declaration letter | Affidavit |
|---|---|---|
| Paper | Letterhead or plain paper | Non-judicial stamp paper |
| Who signs | You, as proprietor | You, sworn before a notary |
| Cost | Nothing beyond printing | Stamp paper plus notary fees |
| When to use | When the asker accepts a plain signed letter | Only when the asker says an affidavit is needed |
The text of a proprietorship affidavit format is close to the letter above, but it starts with "I, [name], do hereby solemnly affirm and declare" and ends with a verification line.
Stamp paper value differs by state and by purpose, so ask the asker what value they want and buy it from an authorised vendor.
Do not swear an affidavit by default. Most askers are happy with a signed letter, and an affidavit only adds cost and time.
If you do need one, keep these points in mind:
- Buy the paper in your own name: Ask the asker what stamp paper they accept, and have it bought in your name as proprietor.
- Sign in front of the notary: Do not sign beforehand. The notary needs to see you sign and will check your identity, so carry your ID.
- Keep a copy: Scan the sworn affidavit before you hand it over, as some askers keep the original.
FSSAI self-declaration for a proprietorship and how it differs
When you apply for an FSSAI licence or registration as a proprietor, the FoSCoS portal asks for proof of the business's constitution.
For a proprietorship, FoSCoS lists a self-declaration for this and offers a sample format for it in its list of documents.
The official FSSAI self-declaration for proprietorship format is a one-page form to be given on the letterhead of the food business.
In it, you state that you are the sole owner of the business under its trade name and premises address, that it is not run by a partnership firm or limited liability partnership, and that the contents are true.
The form also asks you to name a legal nominee for the business and their relationship to you, and ends with your signature with stamp or seal, name, address, contact numbers, place and date.
The sample itself does not mention stamp paper or a notary.
The FSSAI version differs from the bank one in two ways:
- Whose format: Use the FoSCoS sample, not a bank or general letter, so the wording matches what the portal expects.
- What it covers: It confirms you are the sole proprietor of the food business named in the application, rather than asking for an account to be opened. It also names a legal nominee, which a bank letter usually leaves out.
The format and any attestation can change, so download the latest sample from the FoSCoS document list before you sign.
Declaration, certificate of proprietorship and Udyam: which proof is which
People often mix up these papers, but each does a different job as proof of proprietorship.
- Declaration: Your own signed statement that you alone own the firm. It usually goes alongside other documents rather than standing alone.
- Certificate of proprietorship: There is no single certificate issued for a proprietorship. In practice, people mean the registrations the firm holds, which the sole proprietorship registration guide walks through.
- Udyam registration: An online registration for MSMEs on the Udyam portal. Banks often accept it as one of the business proofs they ask for.
A declaration and a registration work together rather than replacing each other: the declaration tells the asker who owns the firm, and the registration shows the firm exists.
Other papers banks accept as business proof include a GST certificate, a shop and establishment licence and, for exporters, an IEC. For a fuller picture of how this structure works, see the sole proprietorship guide.
How Xflow helps a sole proprietorship receive payments from abroad

- Many currencies: Clients can pay in 25+ currencies, including USD, GBP, EUR, CAD, AUD, AED and SGD.
- Fast INR payout: Funds reach your Indian bank account in INR within 1 business day.
- Export paperwork: An eFIRA is issued for each payment, which helps with export records.
Which proprietorship declaration should you use
For most askers, a signed letter on letterhead or plain paper is enough, using the sample text above. Use the bank's own form if it gives you one, and the FoSCoS sample for an FSSAI application.
Go for an affidavit on stamp paper only when the asker says it must be one.
Frequently asked questions
The declaration is a signed statement in which the owner confirms they alone own and run the business, with no partners. Banks, FSSAI and some clients ask for it to confirm who is behind the firm.
No. RBI KYC rules ask banks to verify the proprietor and collect business proofs, but they do not list a declaration. Banks that ask for one do so under their own policy.
Usually not. A signed letter on letterhead or plain paper is enough for most askers. Use stamp paper and a notary only when the asker says it must be an affidavit.
No. FSSAI has its own sample format on the FoSCoS portal for the licence application. A bank either gives you its form or accepts a letter addressed to the branch.
Yes. The declaration itself needs no registration. The asker may still want other business proof, such as a GST or Udyam certificate, next to it.
The declaration would no longer be true, because the firm would no longer have one owner. A business with partners is a partnership, so the paperwork changes with it.
Only the proprietor signs it. Nobody else can, because no one else has a stake in the business.
