The article examines the impact of regulatory changes in the tax on dividends on the payout policy of Indian companies. The tax law was recently amended to levy tax on dividends received by large shareholders. As the promoters group is the largest shareholder, this is expected to have a negative impact on the payout policy of companies. Furthermore, companies with larger promoter holdings have a higher motivation to reduce their payout. The study covers 370 companies present in the BSE 500 Index and compares the dividend payout of the companies before and after the introduction of tax levy. The study finds that the newly introduced tax indeed caused a shift in the dividend policy of companies, particularly those companies which have high levels of inside ownership. The findings have significant implications for companies, investors and the government.
