As a result of wartime revenue acts, ____________________.

A) the government was able to fund the war fully through increased taxes
B) corporations paid more in taxes than did individual workers
C) rises in the real income of Americans declined due to tax increases
D) the number of Americans paying income tax increased significantly

The wartime revenue acts led to a significant increase in the number of Americans who were required to pay income tax. Prior to the acts, only a small percentage of Americans were subject to income tax. However, the acts expanded the tax base to include more individuals and increased tax rates for those already paying. This allowed the government to raise significant revenue to fund the war effort.
