Proof of Business for a Sole Proprietorship

The single most common obstacle for a new proprietor is not registration. It is opening a current account, because the bank asks for proof the business exists and the proprietor has none.

Under the RBI's KYC Master Direction, a bank must establish two separate things before opening a proprietorship current account: the identity of the individual, and the existence of the business. No single document does both, which is why banks ask for two business proofs.

The two-document rule

Industry practice, following the RBI KYC Master Direction, is that a bank collects at least two documents confirming the proprietor's business activity, in addition to the proprietor's own identity and address proof.

Which two is up to you. These are the documents banks accept:

Different banks weight these differently, and some maintain their own internal list. Ask your branch which two they accept before you spend anything, it is a two-minute question that avoids a wasted application.

The fastest workable pair

For most proprietors, the quickest route to two acceptable documents is:

• Udyam registration, free, filed online against Aadhaar and PAN, usually issued the same day
• Plus either GST registration, if your turnover or activity requires it, or the Shop and Establishment licence, if you have premises

If you are below the GST threshold and working from home, Udyam plus a Shop and Establishment licence is usually the practical pair. If you are above the GST threshold, Udyam plus GST is faster and cheaper.

The rule that decides whether it works

Every document must carry the same trade name, spelled identically.

This is where applications fail. If your Udyam certificate says Sharma Design Studio and your GST registration says Sharma Designs, the bank sees two businesses rather than two proofs of one. Fix the name before you file the second document, not after the bank declines the account.

• Decide the trade name once, in writing, before filing anything
• Use the identical spelling, spacing and punctuation on every application
• Keep the proprietor's own name identical across PAN and Aadhaar too
• Make sure the business address matches across all documents

Before you settle on a trade name, search the trademark register. A name free to use today can still infringe a registered mark, and a rebrand after you have printed signage, built a website and told your clients costs many multiples of the search.

Udyam registration, in detail

Beyond bank account opening, Udyam gives access to MSME benefits, priority sector lending, certain subsidy schemes, and the statutory protection on delayed payments from buyers under the MSMED Act, which is the one most proprietors never think to use.

Any site charging you a fee for Udyam registration is charging a service fee, not a government fee. The registration itself is free.

What you need for the account itself

• Proprietor's PAN and Aadhaar
• Two business proof documents, as above
• Proof of the business address
• Passport-size photographs
• Initial deposit, per that bank's requirement

The account is opened in the format Proprietor Name trading as Trade Name, or the bank's equivalent. It is a current account rather than a savings account, because a savings account is not intended for business turnover and banks do act on that.

What proprietors get wrong

• Running the business through a personal savings account, it breaks your accounting and can breach the bank's terms
• Registering for GST solely to satisfy the bank, then missing the returns that follow
• Using slightly different trade names across Udyam, GST and the Shop Act licence
• Choosing a trade name without a trademark search
• Paying a fee for Udyam registration
• Assuming these registrations create limited liability, they do not, and nothing in a proprietorship does

Opening a current account: what banks actually accept

This is the question behind most searches on this topic. A proprietorship has no incorporation certificate, so banks work from a combination of registrations under RBI's KYC framework. Most will ask for any two of the following.

• GST registration certificate in the proprietorship's name
• Udyam registration certificate, which is free and the easiest of these to obtain
• Shop and Establishment registration for the premises
• Professional or trade licence issued by the municipal authority
• Certificate or licence from a statutory or regulatory body, such as FSSAI or IEC
• Income tax return in the proprietor's name showing business income
