How Much Tax Is Taken From a Paycheck? (2024 Guide)
When you receive your paycheck, you probably notice that the amount is significantly lower than your stated salary. That difference represents taxes and deductions withheld by your employer. Understanding exactly what comes out — and why — helps you plan your finances, adjust your W-4, and maximize your take-home pay.
The Four Main Types of Paycheck Tax Deductions
Every American worker subject to withholding sees these four categories of deductions on their pay stub:
- Federal income tax — based on IRS tax brackets
- State income tax — varies by state (0% to 13.3%)
- Social Security — 6.2% of wages
- Medicare — 1.45% of wages
Federal Income Tax Withholding (2024)
Federal income tax is the largest deduction for most workers. The IRS uses a progressive bracket system where higher portions of income are taxed at higher rates. For 2024, the brackets are:
| Rate | Single Filer | Married Filing Jointly |
|---|---|---|
| 10% | $0 – $11,600 | $0 – $23,200 |
| 12% | $11,601 – $47,150 | $23,201 – $94,300 |
| 22% | $47,151 – $100,525 | $94,301 – $201,050 |
| 24% | $100,526 – $191,950 | $201,051 – $383,900 |
| 32% | $191,951 – $243,725 | $383,901 – $487,450 |
| 35% | $243,726 – $609,350 | $487,451 – $731,200 |
| 37% | Over $609,350 | Over $731,200 |
The 2024 standard deduction is $14,600 for single filers and $29,200 for married filers. Your federal taxable income is your gross income minus this deduction (and any pre-tax contributions).
Real Example: $75,000 Salary, Single, Texas
Let's break down a realistic paycheck for someone earning $75,000/year in Texas (no state income tax), filing single, with no deductions:
| Item | Annual | Per Biweekly Paycheck |
|---|---|---|
| Gross Pay | $75,000 | $2,884.62 |
| Federal Standard Deduction | ($14,600) | — |
| Federal Taxable Income | $60,400 | — |
| Federal Income Tax | ($8,374) | ($322) |
| Social Security (6.2%) | ($4,650) | ($179) |
| Medicare (1.45%) | ($1,088) | ($42) |
| State Income Tax | $0 | $0 |
| Net Paycheck | $60,888 | $2,342 |
How State Income Tax Affects Your Paycheck
State income tax varies dramatically across the U.S. Nine states collect no state income tax on wages. Others charge up to 13.3%. On the same $75,000 salary, a California resident would pay approximately $4,200 more per year in state taxes compared to a Texas resident.
FICA Taxes: Social Security and Medicare
FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare. Unlike income taxes, FICA taxes are flat percentages with no standard deduction:
- Social Security: 6.2% on the first $168,600 of wages in 2024
- Medicare: 1.45% on all wages
- Additional Medicare: 0.9% on wages over $200,000 (single) / $250,000 (married)
Your employer pays a matching 6.2% Social Security and 1.45% Medicare on your behalf — for a total employer-employee FICA contribution of 15.3%. Self-employed individuals pay the full 15.3%.
Pre-Tax Deductions That Reduce Your Tax Bill
Several deductions can be taken from your paycheck before taxes are calculated, reducing your taxable income:
- Traditional 401(k) contributions — up to $23,000 in 2024 ($30,500 if 50+)
- Health insurance premiums (employer-sponsored plans)
- Flexible Spending Accounts (FSA)
- Health Savings Accounts (HSA)
- Dependent Care FSA
How to Reduce Taxes on Your Paycheck
- Maximize 401(k) contributions — Every pre-tax dollar contributed reduces your federal and state taxable income.
- Review your W-4 — Claiming the correct allowances prevents over- or under-withholding.
- Use an HSA or FSA — Contributions are triple tax-advantaged (pre-tax contributions, tax-free growth, tax-free withdrawals for qualified expenses).
- Consider state of residence — Moving to a no-income-tax state can save thousands annually.
Frequently Asked Questions
What percentage of my paycheck goes to federal taxes?
Federal income tax ranges from 10% to 37% depending on your taxable income and filing status. However, your effective rate (total federal tax ÷ gross pay) is always lower than your marginal (top bracket) rate because only the income in each bracket is taxed at that rate.
How much is Social Security and Medicare tax?
Social Security tax is 6.2% of wages up to $168,600 in 2024. Medicare tax is 1.45% on all wages. High earners pay an additional 0.9% Medicare surtax on wages above $200,000 (single) or $250,000 (married). Combined, employee FICA taxes are 7.65% for most workers.
Do state taxes come out of every paycheck?
Yes, in states with income tax, your employer withholds state income tax from each paycheck. Nine states have no income tax on wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.
