Tax credit is a kind of tax expenditure implemented in order to encourage companies to participate in government’s economic and social policies. However, if the tax credit provisions do not actually work for any reason, then the government can’t achieve the initially intended policy objective. Therefore, it is a major concern to confirm whether the companies actually realize tax credit opportunities. This paper conducts an empirical study on whether the expenditures on plant & equipment investment or research & development activity have positive effect on permanent book-tax differences, to see if the companies sufficiently realize tax credit opportunities. And this paper performs empirical tests on whether the auditor-provided tax services strengthen the positive effect. The main test results are as follows. First, the expenditures on plant & equipment investment or research & development activity have significantly positive effects on the permanent book-tax differences, which means that companies actually realize tax credit opportunities. Second, the auditor-provided tax services strengthen the positive effect, which means that the knowledge spillover effect of auditor-provided tax services makes a company more fully realize tax credit opportunities. The above empirical results suggest that the tax credit provisions need to be improved for the companies to more fully realize tax credit opportunities for the expenditures on plant & equipment investment. And this paper makes an academic contribution by supplementing the existing studies on the effectiveness of tax credit provisions, and by expanding the existing studies regarding knowledge spillover effect of auditor-provided tax services.
