Limited liability for a single founder — incorporation, nominee filing and first-year compliance.
A One Person Company gives a solo founder the one thing a proprietorship cannot: a separate legal identity, so business debts stop at the business. It is registered under the Companies Act, 2013 with a single shareholder who is also usually the sole director, plus a nominee who steps in if the member dies or becomes incapacitated. We handle the incorporation in Chennai from name reservation through to the certificate, and set up the statutory registers most founders forget about.
Who should register an OPC — and who should not
An OPC suits a single founder who wants limited liability and a corporate identity when dealing with clients, banks or vendors, but has no intention of taking on a partner or raising equity in the near term. It fits consultants, IT service providers, single-owner manufacturers and traders billing corporate customers who insist on dealing with an incorporated entity.
It is the wrong structure if any of the following apply:
You expect to bring in a co-founder or investor. An OPC cannot have a second shareholder, so you would have to convert to a private limited company first.
You want to carry on non-banking financial investment activity. That is expressly barred for an OPC.
You are not an Indian citizen resident in India. Only a natural person who is an Indian citizen can incorporate an OPC or be named as nominee. Residency is tested on days of stay in India in the immediately preceding financial year.
You already hold one OPC. A person can be the member of only one OPC and the nominee of only one OPC at a time.
The old conversion trap is gone. Until the 2021 amendment, an OPC crossing ₹50 lakh paid-up capital or ₹2 crore turnover had to convert into a private limited company. That mandatory conversion has been removed — an OPC can now grow without a forced restructure, and can convert voluntarily whenever it suits you.

How incorporation works
Digital Signature Certificate. A Class 3 DSC is issued for the proposed director after video verification. Nothing can be filed with the MCA without it.
Name reservation. Two proposed names are submitted through SPICe+ Part A. We run a trade mark and MCA name check first — a name that clashes with an existing company or a registered mark is the usual reason for rejection, and a resubmission costs another fortnight.
SPICe+ Part B filed. This single form carries incorporation, DIN allotment for the director, PAN, TAN, EPFO and ESIC registration, professional tax registration for Tamil Nadu, and the bank account opening request.
Linked forms. e-MOA (INC-33), e-AOA (INC-34), the nominee's consent in INC-3, and AGILE-PRO-S for GST if you opt for it at incorporation.
Certificate of Incorporation. Issued with the CIN, along with PAN and TAN. INC-20A, the declaration of commencement of business, must then be filed within 180 days — after the subscription money has actually been paid into the company bank account.
Timeline and cost drivers
Where names are cleanly available and documents are in order, incorporation usually completes in about seven to twelve working days in Tamil Nadu. What actually moves the timeline is name rejection, a mismatch between the address proof and the rent agreement, or a nominee whose Aadhaar and PAN details do not match. Government cost varies with authorised capital and Tamil Nadu stamp duty; the professional fee is quoted after we see the documents.
What you take on after incorporation
An OPC is lighter than a private limited company but it is not compliance-free, and this is where most first-time founders get caught:
Books of account, and an audit by a chartered accountant every year regardless of turnover
Annual return in MGT-7A and financial statements in AOC-4 — note the shorter window: AOC-4 within 180 days of the financial year end
Income tax return at the corporate rate; no basic exemption slab applies
DIR-3 KYC for the director every year by 30 September
Board minutes for at least one meeting in each half of the year where there is more than one director
Yes. The restriction is on members, not directors. An OPC has exactly one shareholder but can appoint up to fifteen directors. Founders often add a second director for operational convenience without diluting ownership.
The nominee named in Form INC-3 becomes the member automatically and must file INC-4 to record the change, along with a fresh nominee consent. This is why the nominee choice matters more than most founders assume at incorporation.
Usually not at low profit levels. A proprietorship is taxed in the individual's slab and gets the basic exemption; an OPC pays the flat corporate rate on the first rupee of profit, and dividends drawn out are taxed again in your hands. Salary and director remuneration change the arithmetic. We work out the comparison on your expected numbers before you incorporate.
Yes, voluntarily at any time by increasing the membership, appointing a second director and filing INC-6. Since the 2021 amendment there is no longer a two-year waiting period or a mandatory conversion threshold.
