Choosing the right entity structure is one of the few decisions a founder makes that is hard to undo. Many start ups begin with a Private Limited because that is what investors expect. Others choose an LLP for tax reasons. A few choose OPC because incorporation is simple. The right choice depends on a small set of variables.
Tax
Private Limited and OPC pay corporate tax at 22 percent under the new regime, with no MAT, plus surcharge and cess. LLPs pay at 30 percent plus surcharge and cess but avoid the dividend distribution complexity. Pass through is not available for either; pass through entities like AIF Category I and II are governed by separate rules.
Funding
Equity investors prefer Private Limited. Convertibles, ESOPs and orderly cap tables work in Private Limited. LLPs cannot issue equity in the conventional sense and are ill suited to venture funding. OPC must convert to Private Limited beyond a turnover threshold.
Compliance
Private Limited carries the heaviest compliance load. LLP and OPC are lighter, but lighter is not free. The deciding factor is rarely compliance cost; it is usually the funding strategy and exit planning.
Foreign founders and overseas operations
FDI rules are simpler for Private Limited. ECB is available to a wider class of Private Limited companies. ODI from India is straightforward from any of the three forms but the receiving entity's structure abroad matters more.
The recommendation
For a venture backed start up: Private Limited from day one. For a small services firm with no investor plans: LLP. For a sole proprietor consultant testing the market: OPC, with an eye on the conversion thresholds.
