This study investigates the impact of cash flow rights and cash-vote divergence on the self-assessed income before tax behavior. We find that the controlling shareholder’s to master larger cash flow rights with a positive impact on the self-assessed income before tax, and once the release of its disclosure and the quality of the smaller error resulting in a greater incentive to do an effective supervisor in line with the interests of shareholders. We further consider the impact of cash flow rights of the endogenous variables whose problem will lead to bias coefficient estimates of a two-stage regression as well as empirical results with this hypothesis also received strong support. However, compared to larger cash flow rights of firms, the option when there is cash-vote divergence on the self-assessed income before tax and notice the quality below the level of significance revealed that will be expressed that firms with cash-vote divergence on the self-assessed income before tax and notice the quality no influence.
