End-to-end workflow for preparing and filing an Indian company's corporate income tax return (ITR-6) including MAT computation, Form 3CD tax audit report, advance tax scheduling, and TDS reconciliation via Form 26AS/AIS.
Establish the company's legal status, residential status, and applicable tax regime. Confirm whether the company is a domestic company or foreign company, identify if it is covered by Section 115BAA (flat 22% regime) or Section 115BAB (new manufacturing company at 15%), and verify TAN/PAN details. This phase gates everything downstream.
Determine whether a tax audit under Section 44AB is mandatory (turnover above INR 10 crore for business, INR 50 lakh for professionals, or triggers under presumptive provisions). Collect audited financial statements and the statutory audit report. Prepare the engagement scope for Form 3CD (tax audit report) if required.
Compute taxable income under each head, starting from net profit per books and applying additions/disallowances (Sections 37, 40, 40A, 43B) and deductions (Chapter VI-A). Separately compute Book Profit under Section 115JB for Minimum Alternate Tax (MAT) at 15% of book profit, and determine whether normal tax or MAT is higher. Carry forward MAT credit under Section 115JAA if MAT exceeds normal tax.
Verify that advance tax instalments were paid on time (15 June, 15 September, 15 December, 15 March) in the correct proportions (15%, 45%, 75%, 100% of assessed tax). Compute interest under Section 234B (shortfall in advance tax) and Section 234C (deferment of instalments). Identify any excess advance tax paid for refund claim.
Complete all 44 clauses of Form 3CD in the prescribed XML format. Key clauses include Clause 13 (method of accounting), Clause 17 (depreciation), Clause 19 (amounts deductible under Section 43B), Clause 21 (payments to specified persons), Clause 26 (payments outside India / Form 15CA-CB), and Clause 44 (GST reconciliation of turnover). The Chartered Accountant signs Form 3CA/3CB + 3CD using DSC and uploads to the Income Tax portal.
Prepare ITR-6 (applicable to all companies except those claiming exemption under Section 11). Enter income computation schedules (Schedule BP for business income, Schedule DPM for depreciation, Schedule ESR for scientific research deductions), claim Chapter VI-A deductions, and compute final tax liability with applicable surcharge (7% for income INR 1–10 crore, 12% above INR 10 crore) and health and education cess (4%). File using the company's authorised signatory DSC on the Income Tax e-filing portal (incometax.gov.in). Due date: 31 October for tax-audited companies.
Confirm ITR-6 is e-verified (auto-verified on filing by authorised DSC for companies — no physical ITR-V required). Monitor Form 26AS and AIS for any mismatch notices under Section 143(1)(a). Track refund status via the Income Tax portal. Respond to any Section 139(9) defective return notices or Section 143(1) intimations within the prescribed 15-day window.
