How do tax brackets influence after-tax income as salary rises?

• A. All income is taxed at the same rate, so after-tax income increases proportionally.
• B. Tax brackets only affect capital gains, not wages.
• C. Earnings in higher brackets are taxed at higher marginal rates; thus after-tax income grows more slowly as salary increases.
• D. Higher salary reduces taxes.

Answer: (C)

In a progressive tax system, earnings are taxed in brackets, and each higher dollar you earn isn’t taxed at the same rate. As your salary rises, portions of your income move into higher tax rates, so the extra money you gain doesn’t all come through tax-free. The value of each additional dollar after taxes grows, but not as quickly as before because the portion entering higher brackets is taxed more heavily. That’s why after-tax income increases, but more slowly as salary climbs. For example, if you cross into a higher bracket, the portion of your income in that bracket is taxed at a higher rate, so the marginal dollar you earn adds less to your take-home pay than the dollar before you hit that bracket. This illustrates why after-tax income doesn’t rise proportionally with salary. Other statements aren’t accurate reflections of how wages are taxed: tax brackets affect wages (not just capital gains), taxes don’t decrease as your salary increases, and not all income is taxed at the same rate.
