Business & Corporate Tax — Explained

How a business is taxed depends on its form — proprietorship, partnership firm, LLP or company — and on whether it opts for presumptive taxation or keeps full books.

When a tax audit is required

  • Business turnover above ₹1 crore — or ₹10 crore where cash receipts and payments are each within 5%.
  • Professional receipts above ₹50 lakh (₹75 lakh in specified cases).
  • Declaring profit below the presumptive rate while income exceeds the basic exemption limit (after opting out within five years).
  • The audit report (Form 3CA/3CB-3CD, now one Form 26) is signed by a practising Chartered Accountant.

Partners and LLPs

  • Interest on partner capital up to 12% and remuneration within limits are deductible to the firm; TDS at 10% applies above ₹20,000 s.194T→s.393.
  • A partner's share of profit is exempt in the partner's hands; interest and remuneration are taxable as business income.
  • LLPs file Form 11 and Form 8 with MCA besides the income-tax return.

Frequently asked questions

Not always. An LLP pays about 31.2–34.9%, with no tax on profit share in partners' hands. A company can pay 25.17% under the concessional option, but dividends are taxed again in shareholders' hands. The right choice depends on profit level and how money is taken out.

F&O is non-speculative business, so presumptive taxation is possible within the turnover limit — but the five-year lock-in and audit consequences need a careful look first. See the trading guide.

No. A proprietorship is not a separate taxpayer; business profit is part of the owner's income.
