Business Tax Filing — every structure, every compliance, on time.
Income tax filing for companies, LLPs, partnership firms, and proprietorships — return preparation, tax audit, advance tax planning, and TDS compliance by Chartered Accountants in Mumbai.
Contact UsBusiness income tax compliance in India is not a single deadline — it is a year-round cycle of advance tax payments, TDS deductions and deposits, quarterly return filings, and the annual income tax return supported by audited financial statements and, in many cases, a formal tax audit under Section 44AB. The applicable ITR form, tax rate, and compliance obligations differ by business structure: companies file ITR-6, firms and LLPs file ITR-5, proprietors file ITR-3 or ITR-4.
Corporate tax planning has gained new dimensions since the introduction of the concessional 22% regime under Section 115BAA and the 15% rate for new manufacturers under Section 115BAB. The choice between regimes is a significant long-term decision — it affects depreciation claims, deductions under Chapter VI-A, and MAT applicability. For firms and proprietorships, the question is often whether presumptive taxation provides a net benefit over regular taxation with full expense deductions.

We handle the complete cycle — financial statement preparation, tax computation, advance tax planning, tax audit where required, TDS compliance review, and ITR preparation and filing — ensuring that every compliance due date is met and every permissible deduction is captured.
