Because higher corporate taxes lowers the rate of wages paid by more than the corporate tax paid.

We examine the extent to which taxes on corporate income are shifted onto the workforce in the form of lower wages. We use data on 23,000 companies located in 10 countries over the period 1993-2003. We identify two channels by which taxes can affect wages: indirectly through a lower capital stock, and more directly through wage bargaining for net of tax, location-specific rents. We find that a significant part of the effective incidence of the tax falls on wages. Our central estimate is that 54% of any additional tax is passed on in lower wages, even in the short run; other estimates are larger than this. In the longer run, a $1 rise in the tax liability results in a fall in total employee compensation in excess of $1.
