By changing the relative gain to incorporation, corporate taxation can
play an important role in a firm's choice of organizational form. Gen
eral equilibrium models have shown that substantial shifting of organi
zational form in response to tax rates implies a large deadweight loss
of taxation. This paper estimates the impact of taxes on organization
al form using data from 1900-1939. The results indicate that the effec
t of taxes is significant but small. A. corporate rate increase of 0.1
0 raises the non-corporate share of capital 0.002-0.03. The implied de
adweight loss of the corporate income tax is around 5-10% of revenue.
