Why Is So Much Tax Taken from My Paycheck?
Your paycheck has multiple deductions before you see a cent: federal income tax (based on the 2026 brackets and your W-4), Social Security tax (6.2%), Medicare tax (1.5%), and often state income tax. Together these can take 25-35% of gross pay, depending on your income and state. Below is a line-by-line explanation of where your money goes, with a worked example for a $60,000 salary.
Federal income tax withholding
Federal income tax is the largest variable deduction on most paychecks. The 2026tax system uses seven progressive brackets for single filers, from10% on the first $12,400 of taxable income to 37% on taxable income above $640,600.
"Progressive" means only the income within each bracket is taxed at that bracket's rate. If your taxable income is $43,900 (after the $16,100 standard deduction), the first $12,400 is taxed at 10%, the next $38,000 at12%, and the remainder at22%. You are never taxed at a single flat rate on all your income.
Your employer estimates your annual tax based on the W-4 you submitted and divides it evenly across pay periods. If the W-4 does not reflect your actual situation (wrong filing status, missing Step 2 for dual earners), the estimate can be too high or too low. See How to Adjust Your W-4 Withholding for instructions on fixing this.
Social Security tax
Social Security (OASDI) takes a flat 6.2% of your gross wages up to the 2026 wage base of $184,500. Your employer matches this amount. Once your year-to-date wages reach $184,500, the withholding stops for the rest of the year.
On a $60,000 salary, your total Social Security tax is $3,720 for the year. Since $60,000is below the wage base, every paycheck will show the same 6.2% deduction.
Medicare tax
Medicare tax is 1.5% on all wages, with no cap. Your employer matches the 1.5% contribution. On $60,000, your annual Medicare tax is $870.
If your wages exceed $200,000 (for single filers), you also pay the Additional Medicare Tax of 0.9% on the excess. This surtax is employee-only; your employer does not match it. At $60,000, you are well below this threshold.
Use the FICA calculator to see your combined Social Security and Medicare totals.
State and local taxes
Most states impose their own income tax, which your employer also withholds. Rates vary widely: some states have a flat rate under 5%, others have progressive brackets reaching above 10%. Nine states (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming) have no state income tax on wages at all.
Some cities and counties add local income taxes on top of the state rate. If you live or work in one of these jurisdictions, you will see an additional line item on your pay stub.

Pre-tax deductions (401k, health insurance)
Many employers offer benefits that are deducted from your paycheck before income tax is calculated. These "pre-tax" deductions reduce your taxable income, which means less federal and state income tax withheld. Common examples:
- 401(k) contributions: Up to $24,500 per year in 2026 ($8,000 additional if age 50+). These reduce your taxable income but are still subject to FICA.
- Health insurance premiums: Employer-sponsored health insurance premiums paid through a Section 125 cafeteria plan reduce both income tax and FICA.
- HSA contributions: Up to $4,400 (self-only) or $8,750 (family) in 2026. Payroll HSA contributions reduce both income tax and FICA.
- FSA contributions: Flexible spending accounts for medical or dependent care expenses also reduce taxable income.
These deductions help you save on taxes but they also reduce your take-home pay. If you are contributing 6% to a 401(k) plus paying $200/month for health insurance, those amounts come out of your gross pay before withholding is calculated.
Why your net pay is lower than expected
When you add up all the deductions, the gap between your gross salary and your take-home pay becomes clear.
Worked Example: $60,000 Salary, Single Filer, Biweekly Pay
Gross pay per period: $60,000 / 26 = $2,307.69
Federal income tax: Taxable income = $60,000 - $16,100 = $43,900. Annual tax across the 10%, 12%, and 22% brackets = approximately $5,020. Per period: $193.08
Social Security: $2,307.69 x 6.2% = $143.08
Medicare: $2,307.69 x 1.5% = $33.46
Total federal deductions: $369.62 per pay period
Net pay (before state tax and benefits): $1,938.08
Effective federal rate: 16.0%
State income tax, health insurance premiums, 401(k) contributions, and other benefits would reduce this further. In a state with a 5% income tax, the total deduction rate could reach 30% or more of gross pay.
The key takeaway: most of the gap between your salary and your bank deposit is not one big tax, but the sum of many smaller withholdings. Federal income tax, Social Security, Medicare, state tax, and voluntary benefits each take a slice.
