For companies that do not require a tax audit: October 31 of the assessment year (e.g., October 31, 2025 for FY 2024-25). For companies that require a tax audit (turnover > ₹1 crore for non-digital businesses, ₹10 crores for digital): Also October 31 (tax audit report to be submitted by September 30). For companies with international transactions or specified domestic transactions requiring a transfer pricing report: November 30. Note: these due dates are frequently extended by the CBDT via circulars. We track all extensions and ensure timely filing.

GSTR-1 is the outward supplies statement — you declare all your sales invoices here. Filed monthly (by 11th of next month) for taxpayers with turnover above ₹5 crore, and quarterly (QRMP scheme) for others. GSTR-3B is the monthly self-assessment return — you declare summary sales, ITC claimed, and pay GST liability. Filed monthly by the 20th (or 22nd/24th for quarterly filers). GSTR-9 is the annual GST return — a comprehensive reconciliation of the entire year's GSTR-1 and GSTR-3B data. Due by December 31 of the following year. For taxpayers with turnover above ₹5 crore, GSTR-9C (reconciliation statement, certified by CA) is also required.

TDS (Tax Deducted at Source) is a system where the payer deducts tax at source before making certain payments. Businesses must deduct TDS on: salary payments (Section 192), contractor payments above ₹30,000/single or ₹1 lakh/year (Section 194C), professional fees above ₹30,000/year (Section 194J), rent payments above ₹2.4 lakhs/year (Section 194I), and interest on loans (Section 194A). The deducted amount must be deposited by Challan 281 by the 7th of the following month (7th of April for March). Quarterly TDS returns (Form 24Q for salary, Form 26Q for others) are due 31 days after quarter end. Non-compliance leads to interest at 1.5% per month plus 1% per month on late deposit.

GST registration is mandatory if: (1) Your aggregate annual turnover exceeds ₹40 lakhs (₹20 lakhs for special category states) for supply of goods; (2) ₹20 lakhs for service providers (₹10 lakhs for special category states); (3) You sell goods/services interstate regardless of turnover; (4) You sell on e-commerce platforms (Amazon, Flipkart, etc.) regardless of turnover; (5) You are liable to pay GST under reverse charge. Voluntary registration is beneficial even below threshold if your clients are GST-registered businesses, as they can claim ITC on your invoices. Registering below threshold but having 0% turnover still requires nil returns to be filed.

Tax audit under Section 44AB requires a Chartered Accountant to audit books of accounts and issue Form 3CA/3CB + Form 3CD. Mandatory for: (1) Business: if total sales/turnover exceeds ₹1 crore (₹10 crore if cash transactions are less than 5% of total); (2) Profession: if gross receipts exceed ₹50 lakh (₹75 lakh if at least 95% receipts and payments through banking); (3) Companies that opt out of presumptive taxation under Section 44AD/44ADA; (4) Companies with international transactions (Transfer Pricing Audit under Section 92E). The due date for filing the tax audit report is September 30. Not getting a mandatory audit leads to penalty of 0.5% of turnover or ₹1.5 lakh, whichever is lower.
