Every founder asks the same question on the first call: which structure should I register? It feels like a small admin choice. It is not. The entity you pick decides how you raise money, how much tax you pay, and how much compliance you carry for the next several years.
A Private Limited company is the right answer if you intend to raise external funding. Investors expect equity shares, a board, and the governance that comes with them. The trade off is more compliance: board meetings, annual filings and audits.
An LLP suits a profitable services business with a few partners who want limited liability without the heavier compliance of a company. You cannot easily raise venture money into an LLP, so it is rarely right for a startup chasing investors.
A One Person Company lets a solo founder get the protection of a company structure while keeping full control, and it can convert to a Private Limited later as you grow.
The honest answer is that it depends on your plan, not on what is cheapest to file. That is the conversation we have on the free call, and it is the single most valuable thirty minutes most first time founders spend.
