Purpose – The purpose of this paper is to investigate the association between corporate tax aggressiveness and cash holdings and that between corporate tax aggressiveness and the value of cash. Further, this study explores the impact of the tax enforcement level on the above associations. Design/methodology/approach – Under a Chinese special institutional background, this study constructs tax aggressiveness and tax enforcement measures. On this basis, using a sample of Chinese A-share listed companies over the period from 1990 to 2010, this study empirically tests the association between tax enforcement, corporate tax aggressiveness, and cash holdings. Findings – By empirically testing with Chinese listed companies as the sample, this paper finds the following: with the increase in the tax avoidance level, the precautionary incentives of cash, and the level of financial constraint likewise increase, which will make the level of firm cash savings increase. Meanwhile, although tax avoidance will induce lower transparency and higher agency costs, the marginal value of the cash held by the more aggressive firms is higher due to the higher market competition effect of the cash. Additional tests suggest that, the tax enforcement level can weaken the effect of tax avoidance on the transparency and agency problem; however, because the tax enforcement level can also increase the tax risk of the firm, the positive relation between firm’s tax avoidance and cash savings is strengthened correspondingly. On the value of cash holdings, the tax enforcement level can also make the marginal value of tax aggressive firms higher. Originality/value – First, this paper provides new evidence on the determinants of firm’s cash holdings from the perspective of cash savings. Second, this paper examines the association between Chinese firm’s tax aggressiveness and the value of cash, which not only provides evidence for the local tax literature but also has reference value for the foreign literature. Third, this paper has reference value for research on the association between corporate tax avoidance activities and other operating decisions. Finally, this paper not only provides new evidence on the association between tax enforcement and corporate governance, but also extends the prior literature on the association between corporate tax aggressiveness and cash holdings.
