What does limited liability actually protect in an OPC?
A proprietorship has no legal existence apart from you. A supplier's unpaid invoice, a warehouse lease dispute or a customer injury claim can be recovered from your savings, your car or your flat. An OPC is a separate company, so the company's debts are generally the company's, not yours.
In practice the protection is thinner than it sounds for a new seller:
- Personal guarantees. Banks, NBFCs and some suppliers ask the director to guarantee the company's loans or credit limits. Once you sign, you are personally liable for that amount whatever the structure.
- Product liability. If you sell food, cosmetics, electronics or children's products, the company is the seller on record, which helps. But a director can still be pursued for their own wrongful acts, and consumer and regulatory claims often name individuals too.
So limited liability is worth paying for when you hold credit stock, sell risky categories or plan to borrow without guarantees. It is not worth much if you drop-ship low-risk items with little credit exposure.
What does it cost to set up an OPC vs a proprietorship?
A proprietorship needs no incorporation. You use your own PAN and then take GST registration, Udyam if you want it, and any local licence. Cost is mostly the GST filing set-up and professional fee.
An OPC is incorporated through the MCA's SPICe+ process, which needs a digital signature, a director identification number, a name approval, a Memorandum and Articles that name your nominee, and the nominee's consent. The cost components are the MCA filing fees (which depend on authorised capital), stamp duty on the incorporation documents (which differs by state), digital signature and professional fees. We are not quoting numbers here because state stamp duty and MCA fees change; ask for a written breakdown before you pay anyone.
Why does an OPC cost more to run each year?
This is the part new founders underestimate. An OPC has to do these every year, even if sales are tiny or nil:
- Statutory audit by a chartered accountant, with the auditor appointed and reported to the registrar.
- ROC filings: financial statements (Form AOC-4) and the shorter annual return (Form MGT-7A). Late fees run per day, per form, with no cap, so missing the date gets expensive.
- Director KYC each year, or the DIN is deactivated.
- Company income tax return and bookkeeping to company-law standards, usually needing a regular accountant.
An OPC does not hold an AGM, and a single-director OPC has relaxed board meeting rules, which removes some paperwork. A proprietor files an income tax return and GST returns, and needs a tax audit only above the income-tax turnover limits. Running cost is the biggest practical gap between the two.
How is an OPC taxed compared with a proprietorship?
A proprietor's profit is taxed in your hands at individual slab rates, so the effective rate rises as profit rises. A proprietor may also be eligible for a presumptive scheme on small turnover; check eligibility, as companies cannot use it.
An OPC pays company tax on its profit. The Income-tax Act, 2025 (in force from 1 April 2026) keeps an optional concessional rate for domestic companies: 22% (the regime that was section 115BAA under the old Act), plus surcharge and cess, and the company must give up certain deductions and incentives and opt in by the return due date. Other company rates exist under other conditions. Then, if you take profit out as salary or dividend, that is taxed again in your hands. Salary to yourself is a deductible cost to the company but taxable for you.
The honest summary: at low profit a proprietorship is often cheaper once you count the OPC's audit and filings. At higher, retained profit the company rate can work out lower. A CA should run both on your real numbers.
Does the structure affect bank, payment gateway and marketplace onboarding?
Both can open a current account and sell on Amazon, Flipkart, Meesho or Shopify. Differences are mostly paperwork:
- Proprietorship: the account is in the business name using your PAN, GST registration and usually Udyam or similar proof. Quick to open at most banks.
- OPC: the bank asks for incorporation papers, MoA and AoA, board resolution and the director's KYC. It takes longer, and some banks ask for a personal guarantee on credit lines.
- Payment gateways and marketplaces: they verify the business PAN, GST and bank account match. Requirements vary by provider and change, so check the current list in your dashboard.
One tax point: marketplaces deduct income-tax TDS at 0.1% (section 393(1) of the Income-tax Act, 2025, formerly 194-O). The nil-TDS relief up to ₹5 lakh is for resident individuals and HUFs with PAN or Aadhaar, so an OPC, being a company, should expect TDS from the first rupee. GST TCS of 0.5% applies either way. See our guide to selling on Amazon without GST for the GST side.
Can you raise money later with an OPC or a proprietorship?
A proprietorship has no shares, so there is nothing for an investor to buy. To bring in a partner or investor you would set up a new entity and move the business into it.
An OPC can have only one member, so it cannot take an investor directly. But it can convert to a private limited company by filing Form INC-6, after which you add the second member and director. Since 1 April 2021, there is no waiting period or minimum capital for this, and the old forced conversion at ₹50 lakh capital or ₹2 crore turnover no longer applies.
What happens to your GSTIN and seller accounts if you switch later?
If you start as a proprietor and move to an OPC, the business is a different legal person with a different PAN, so it needs a new GSTIN. Marketplaces generally treat the seller account as tied to the legal entity and PAN, so expect to open a new seller account and re-list, rather than renaming the old one. Amazon staff have said this in seller forum replies; confirm in your Seller Central or Flipkart dashboard first.
Converting an OPC to a Pvt Ltd later is gentler, because it stays the same company, but update your GST and marketplace records and ask each platform what documents it wants. If you want the full structure comparison including LLP and Pvt Ltd, read our four-way structure comparison.
OPC or proprietorship: which should you choose?
Choose a proprietorship if:
- You are testing a product and profit is small or uncertain.
- Your categories are low-risk and you hold little stock on credit.
- You do not want an audit and annual ROC filings yet.
- You do not expect outside investment in the next year or two.
Choose an OPC if:
- You want your personal assets separated from business risk, and you can run clean books.
- You sell higher-risk products or will carry real inventory or supplier credit.
- You expect profits to be retained and reinvested, and a CA says the company rate helps.
- You may want investors or co-founders later and prefer a path that converts to a Pvt Ltd.

Ask on WhatsAppRelated questions
Is an OPC or proprietorship better for an online business?
Neither is better for everyone. A proprietorship suits a low-risk, low-stock start with minimal compliance. An OPC suits a solo founder who wants limited liability, expects higher profit or may add investors later, and accepts the yearly audit and filings.
Can a sole proprietorship sell on Amazon and Flipkart?
Yes. Proprietorships sell on major marketplaces using the owner's PAN, GST registration and a bank account in the business name. Marketplace document requirements change, so check the current list in your seller dashboard.
Can I convert a proprietorship into an OPC?
There is no direct conversion. The OPC is a new legal entity, so you incorporate it, get a new GSTIN and move the business, stock and accounts over. Marketplace accounts usually need to be re-opened or migrated; confirm with each platform.
Can one person own more than one OPC?
No. A person can be the sole member of only one OPC at a time. The same person can still be a director in other companies, subject to the usual limits.
Does an OPC with no sales still have to file returns?
Yes. A dormant OPC still has to get its accounts audited and file with the registrar, and director KYC is still due. Late fees apply per day. Ask a CA about closing the company if you stop trading.
