USA Workforce Tax Credit Act This bill amends the Internal Revenue Code to allow tax credits for charitable contributions to certain nonprofit organizations with the exclusive purpose of providing: (1) workforce development and apprenticeship training, or (2) scholarships for elementary and secondary education expenses of students from households with income that does not exceed 200% of the median gross income. The bill limits the credits to specified amounts for individuals and corporations. It also: (1) imposes a tax on workforce development, apprenticeship training, and scholarship granting organizations that fail to distribute a specified portion of their receipts; and (2) establishes a $2 billion annual volume cap for the tax credits allowed under this bill.
