When you look at your pay stub, it can feel like a big chunk of your earnings just disappears. Here is exactly where it goes — and why each deduction exists.
Your gross pay is the starting number — your salary or hourly wage before anything is taken out. From there, several mandatory deductions are applied before you see a cent.
This is the big one for most people. The federal government takes a percentage of your earnings based on a progressive tax system with seven brackets from 10% to 37%. The exact amount depends on your annual salary, filing status, and any pre-tax deductions like 401k contributions. In 2026, the standard deduction is $15,000 for single filers, which means you only pay federal tax on income above that amount.
Most states add their own income tax on top of federal tax. Rates range from under 3% to over 9%. Nine states — Texas, Florida, Nevada, Washington, Wyoming, South Dakota, Tennessee, New Hampshire, and Alaska — collect no state income tax at all, which means workers there keep more of every paycheck.
Social Security is a federal program that provides retirement, disability, and survivor benefits. You pay 6.2% of your wages up to the 2026 wage base of $168,600. Once your earnings exceed that threshold for the year, no additional Social Security tax is deducted for the rest of the year — which is why some higher earners notice their paychecks get slightly bigger later in the year.
Medicare funds health insurance for people aged 65 and older and certain disabled people. Unlike Social Security, there is no wage cap on Medicare — you pay 1.45% on all earnings. High earners (over $200,000 for single filers) pay an additional 0.9% Medicare surtax.
If you contribute to a 401k, traditional IRA, HSA, or employer-sponsored health insurance, these deductions come out before taxes are calculated. This is genuinely valuable — every dollar you contribute to a 401k reduces your taxable income by one dollar, lowering your federal and state tax bill simultaneously.
The most effective way to increase your take-home pay without asking for a raise is to maximise pre-tax deductions. A $500/month 401k contribution might only reduce your paycheck by $390 or so — because you save on taxes too. Over a year, you have contributed $6,000 to retirement while only "feeling" $4,680 less in your pocket.
