Two Types of Payments of Tax on Profit: Advanced Payments and at the End of Periods: Consideration within BFO Theory with Variable Profit

Abstract

Two modifications of a modern theory of capital structure—the Brusov–Filatova–Orekhova (BFO) theory—with variable income are considered: (1) with the income tax payments at the end of periods and (2) with advance income tax payments. BFO formulas for the WACC, and for company capitalization, V, were derived for these two cases. Using the obtained formulas, the dependence of the weighted average cost of capital, WACC; the discount rate; WACC–g (here, g, is the growth rate); company value, V; and the equity cost, ke, on the leverage level, L, at different values of g, at different values of the debt capital cost, kd, and at different values of company age, n, were studied. Comparing the results for cases (1) and (2) shows that case (2) is always preferable for both the company and the regulator. Recommendations have been developed for both parties to expand the practice of advance income tax payments. The managerial implications are as follows. Companies may choose to pay income tax either in advance or at the end of the reporting period in accordance with current results and tax laws. The developed methodology makes it possible to study companies with growing profits and companies with falling profits, which is very important in practice. It also allows the study of companies for which profits could rise and fall in different periods.
