Can one person start an LLP?
No. An LLP needs at least two partners and two designated partners at all times, and at least one designated partner must be resident in India. If the number of partners drops to one and stays there for more than six months, the remaining partner becomes personally liable for the LLP's debts incurred in that period. That is why a solo founder who wants limited liability has two realistic options: an OPC, or a Private Limited Company with a trusted second shareholder holding as little as one share. An OPC is the cleaner choice if there genuinely is nobody else, because it needs only a nominee, who has no ownership and no say until the member dies or becomes incapable.
Which costs less to keep compliant?
The LLP, by ₹5,000 to 15,000 a year in the market, mainly because it avoids the audit. An OPC is a company, so it must have its accounts audited every year no matter how small it is, and it files AOC-4, MGT-7A, DPT-3 and DIR-3 KYC. It does skip the AGM and board meetings. An LLP files Form 11 by 30 May and Form 8 by 30 October, needs DIR-3 KYC for each designated partner, and is audited only above ₹40 lakh turnover or ₹25 lakh contribution. Late fees also favour the LLP for short delays, since MCA charges a company ₹100 per day per form while LLP late fees start lower and rise with the delay.
How does tax compare between an OPC and an LLP?
An OPC pays corporate tax at 25%, or 22% under Section 115BAA, and the owner then pays slab tax on any dividend. An LLP pays 30% on profits, but a partner's share of profit is exempt in their hands, and the LLP can deduct partner salary and interest within Section 40(b). For a services business whose owners take out most of the profit, the LLP is usually the lower total tax because the profit is taxed once. For a business that keeps profits inside to fund growth, the OPC's 25% rate is lower and the dividend tax is deferred until money is withdrawn. Run the numbers on your expected withdrawals before choosing.
What happens when you want to grow?
An OPC has a built-in upgrade path. When a co-founder or investor arrives, you convert to a Private Limited Company by special resolution and Form INC-6, add the new shareholder, and carry on with the same CIN, PAN and bank account. It takes about 3 to 4 weeks. An LLP can add partners at any time by amending the LLP agreement, which is quick, but it can never issue shares or ESOPs. To take equity funding, an LLP must convert into a company under Section 366, which is a longer process with fresh name approval and creditor consent. If you expect investors, the OPC leads to the destination faster.
