In accordance with the prevailing provisions of the Income Tax Act, 2025 and the Rules framed thereunder, the Company is required to deduct tax at source at the prescribed rates on the dividend paid to its shareholders. The Tax Deducted at Source (“TDS”) rate would vary depending on the residential status of the shareholder and the documents submitted by them and accepted by the Company.
