Abstract

The system of business income taxation consists of two instruments, namely a statutory tax rate and a depreciation allowance on investment. We will show in this paper that by acting on both instruments simultaneously it is possible to achieve both a growth and a fiscal net revenue target even in cases when a trade-off prevails when each instrument is used individually.As will be shown in the paper, depreciation allowances have a more favorable trade-off between growth and net revenue in the long run compared to statutory business income tax rates. Thus, by rising depreciation allowances and the statutory tax rate at the same time, it is possible to both increase growth and fiscal space.In a model simulation calibrated to the German economy and tax system, an increase of the tax depreciation rate for all investments from 10% to 25% leads to a more than 2 percent GDP increase and more than 6 percent higher private investments in total. Whereas GDP and investment rise steadily over time, the government budget becomes negative in the short run. In the long run, the sign of the fiscal budget effect is determined by the indexation of government consumption to GDP. However, according to our findings, slight adjustments in the statutory business income tax rate could balance out these deficits and generate additional fiscal space.
