Carryforwards have become an ordinary feature of the corporate environ
ment. The standard theoretical conclusion is that carryforwards cause
an increase in investment Relative to a no loss offset tax, a loss off
set includes the government as a partner in bearing the risk of a loss
but leaves a gain unaffected. I argue that the standard view ignores
the fact that firms can take actions to central their current tax stat
us. One way that a firm can change its current tax status is to change
its level of debt. I show that if the firm uses risky debt to manage
its current tax status, and the depreciation Tax shield is not too lar
ge, then investment is negatively related to carryforwards.
