A foreign parent looking at Chennai is usually weighing an Indian subsidiary against a branch office. An Indian subsidiary, a private limited company incorporated under Indian law, can invoice locally, hire freely and run full operations. A branch office stays tied to the parent's existing business line and typically needs Reserve Bank approval first. For a company planning to hire a Chennai team, sign local contracts and grow revenue rather than just study the market, the subsidiary route is almost always faster to operate.
Which decision comes before the filing for a foreign parent entering Chennai?
Three choices come before any form reaches ROC Chennai. First, ownership: most sectors allow 100 percent foreign ownership in an Indian subsidiary, though a handful of sectors still cap it or route it through government approval. Second, the paid up capital the parent will inject, since that figure sets the subsidiary's opening balance sheet. Third, the registered office, whether that is a factory address in Ambattur or a delivery centre on the OMR corridor, because the address decides which local Tamil Nadu compliance stack follows incorporation.
- An overseas electronics component maker setting up local assembly in Ambattur Industrial Estate, developed under TANSIDCO, forms an Indian subsidiary to hold the factory, hire staff and bill Indian customers directly.
- A foreign SaaS company opening a delivery centre in Sholinganallur on the OMR corridor uses a subsidiary rather than a branch. A branch cannot carry out software development and sale as a core business without separate approval.
Settling ownership, capital and address first is what keeps drafting and filing moving without a mid process pause.
What documents does a Chennai based subsidiary need from its foreign parent?
The parent company's incorporation certificate, board resolution approving the Indian subsidiary, and its financial statements need notarisation and apostille or consular attestation before they reach ROC Chennai. On the Indian side, a Chennai filing needs the following.
- Registered office proof for the Ambattur or OMR corridor address: a rent agreement, an electricity bill, or a property tax receipt no older than 2 months.
- PAN, Aadhaar and address proof for at least one resident director, since Indian law requires one director who has stayed in India for a set period in the previous year.
- Digital signature certificates and DIN applications for all proposed directors, foreign and resident.
- Draft memorandum and articles, routed through TNREGINET for stamp duty computation before execution, since Tamil Nadu applies the Indian Stamp Act, 1899, as amended for the state.
Attested parent documents are usually what slows a subsidiary filing down, so we start that paperwork on day one.
How does Indian subsidiary registration actually run, step by step?
- We collect the parent company's documents and confirm apostille or consular attestation requirements for the home country.
- Indian side requirements are assembled: resident director details, registered office proof in Chennai, and digital signatures for every director.
- Incorporation forms, the memorandum and articles, and the name reservation request are filed with ROC Chennai on the MCA V3 portal.
- Once ROC Chennai issues the certificate, the CIN carries the Tamil Nadu state code, and we file the FEMA reporting the Reserve Bank requires for the parent's investment.
- We hand over a compliance checklist covering profession tax, Shops Act filing and labour registrations for the subsidiary's first weeks.
Most Chennai subsidiary filings land inside the 20 to 30 day window once apostilled parent documents are in hand.
What does Indian subsidiary registration cost in Chennai?
| Component | What it covers | Typical cost |
|---|---|---|
| Government and ROC fees | Name reservation, incorporation forms and certificate issuance | Included in ₹24,999 |
| Professional drafting | Memorandum, articles and resident director documentation | Included in ₹24,999 |
| FEMA and RBI filings | Reporting the parent's foreign investment after incorporation | Included in ₹24,999 |

Government fees shift a little with authorised capital, so we confirm the final number once the parent's structure is set.
Which registrar and MCA portal actually process your Chennai subsidiary filing?
A Chennai subsidiary filing goes to ROC Chennai, which administers most of Tamil Nadu and was not part of the registrar restructuring carried out in October 2025. Every form moves through the MCA V3 portal, and the certificate carries a CIN with the Tamil Nadu state code built in. If a shareholder or FEMA dispute ever escalates, it lands with the NCLT Chennai Bench, which hears company matters for Tamil Nadu, Puducherry and Lakshadweep. Regional escalations go to the Regional Director, Southern Region Directorate, headquartered right here for Tamil Nadu, Puducherry and the Andaman and Nicobar Islands.
What does a new Chennai subsidiary owe in its first weeks?
Once incorporated, a subsidiary operating from an Ambattur or OMR corridor address inside Greater Chennai Corporation limits registers for profession tax. This produces a single number, the PTNAN, on a half yearly cycle due 30 September and 31 March. If the subsidiary hires 10 or more workers, a Tamil Nadu Shops and Establishments registration follows online through labour.tn.gov.in. EPF coverage begins at 20 employees nationally, and once triggered it continues even if headcount later falls. ESI coverage carries its own separate threshold for factories, and we confirm the applicable figure for an Ambattur manufacturing unit before enrollment. None of these first week filings require an office visit; each runs through its own portal.
