Companies file income tax returns using Form ITR-6 under the Income Tax Act, 1961. Domestic companies are taxed at 25% or 30% + cess + surcharge based on turnover and conditions met. Key compliance aspects include mandatory tax audit (Section 44AB), Minimum Alternate Tax (MAT) calculations under Section 115JB, transfer pricing reporting for international transactions, and GST-income tax reconciliation. We ensure accurate computation, MAT credit optimization, and board-level compliance documentation.
