How does contributing to a pre-tax retirement account affect net take-home pay?

• A. It increases your take-home pay because you save on taxes.
• B. There is no effect on take-home pay.
• C. It lowers your taxable income, which can reduce current withholding; your take-home pay is reduced by the contribution amount.
• D. It increases current withholding.

Answer: (C)

When you contribute to a pre-tax retirement account, the contribution is taken out before taxes are calculated, so your taxable income for that period is reduced. That lower taxable income leads to less tax being withheld from your paycheck. Because part of your earnings is being redirected into retirement, your cash in hand today—your net take-home pay—ends up lower by the amount you contributed (even though the tax withheld is smaller, the contribution itself reduces the take-home cash). In other words, you swap current take-home pay for tax-deferred retirement savings, which is why net take-home pay decreases by the contribution amount while still offering future tax benefits.
