What Is Business ITR: Annual Income Tax Return for Commercial Entities

Business ITR is the annual declaration of income, expenses, deductions, and tax liability. Unlike salaried individuals, businesses compute profit from books (or presumptive income), apply entity-specific tax rates, claim business deductions, and file the appropriate form on the e-filing portal.

The correct form depends on structure and income: individuals/HUFs with business file ITR-3 (full books) or ITR-4 (presumptive). Partnership firms/LLPs file ITR-5. Companies file ITR-6 with mandatory audit, DSC filing, and MAT computation.

For Delhi businesses, this involves reconciling with GST returns, TDS filings, complying with accounting standards, and coordinating tax audit when applicable. Patron manages the complete cycle.

Key Terms for ITR for Business in Delhi:

ITR-3: For individuals/HUFs with business income maintaining full books. Due 31 Aug (non-audit) / 31 Oct (audit).

ITR-4 (Sugam): Presumptive taxation under S.44AD (business Rs 3 crore, 8%/6%) and S.44ADA (profession Rs 75 lakh, 50%). No books, no audit.

ITR-5: Partnership firms, LLPs, AOPs, BOIs. 30% flat rate.

ITR-6: All companies. Mandatory tax audit. DSC filing. 22%/25%/30% rate.
