A bill to amend the Internal Revenue Code of 1954 with respect to contributions to candidates for public office.

Amends the Internal Revenue Code to allow individuals an income tax credit for 75 percent of the sum of all political contributions to candidates for the United States Senate, instead of the 50 percent generally allowed for political contributions. Increases the limitation on credit taken for political contributions to $100 ($200 for joint returns), of which no more than $25 (or $50 for joint returns) may be applied to contributions to candidates for the Senate. Denies the alternative income tax deduction for political contributions for contributions to Senate candidates.
