Federal tax brackets, step by step

Federal tax is not charged on your whole salary. The IRS first lets you subtract the $16,100 standard deduction, so only $13,900 is taxable, and that amount is then taxed bracket by bracket.

Your marginal rate is 12%, but your average federal income tax rate is only 4.7% of gross pay. Moving into a higher bracket never reduces your take-home pay.

How a 401(k) changes your paycheck

Because traditional 401(k) money is taken before income tax, part of every dollar you save is effectively paid by the tax you no longer owe.

ContributionSaved per yearTake-home payPer monthIncome tax saved
None$0$24,945$2,079—
3%$900$24,197$2,016$153

10%$3,000$22,423$1,869$479
15%$4,500$21,148$1,762$703
Putting 6% ($1,800) into a 401(k) only reduces your take-home pay by $1,501: taxes cover the other $299. Many employers also match part of it.
