One Person Company (OPC) Registration Cost in Bihar

Registering an OPC in Bihar typically attracts ₹1,600 in incorporation stamp duty at ₹1 lakh authorised capital, as per commonly published rates — confirm with the Bihar stamp office. Add a Digital Signature Certificate for each director (about ₹1,500 each) and your CA's professional fee, and that's your all-in cost — the MCA government fee is nil up to ₹15 lakh of capital. In practice the Bihar stamp duty is the main figure that sets an OPC apart from the same registration in another state.

That puts Bihar among the more expensive states to incorporate in — the 5th highest of 36. For comparison, Sikkim charges no incorporation stamp duty at all at the same capital.

State stamp duty

Levied on incorporation by the state. The one component that changes from state to state, and the main driver of the total.

Digital Signature Certificate (DSC)

Each director or partner needs one to sign filings — roughly ₹1,500 each as a market estimate.

Professional / CA fee

What your CA or filing service charges to prepare and file the forms. Edit the field to match a real quote.

MCA government fee

The Ministry of Corporate Affairs charges nil for authorised capital up to ₹15 lakh, so most startups pay nothing here.

A single-founder company with limited liability — one director, one member, lighter compliance than a Private Limited.

An OPC suits a solo founder who wants limited liability and a corporate identity without a co-founder or partner. You can convert to a Private Limited later when you take on co-founders or investment.
