While reducing statutory rates would provide a benefit to existing investments and improve the valuation of the company from the point of view of the shareholders, expanding expensing and accelerated depreciation provisions would generate returns over the lifetime of the company by improving cash flows and thereby enhancing firm value. Both types of reforms are critical to firms that are deciding what new investments to undertake and which activities will generate the highest return. In economic terms, the user cost of capital, or the implicit annual cost of investing in physical capital, is determined by not only the headline corporate tax rate, but also other factors such as the rate of depreciation as well as the interest rate. Therefore, any changes to either the tax rates or the provisions affecting the return from capital, would lead to a change in the user cost, which would affect physical capital investments by firms.
