Calculate your take-home pay after federal and state taxes, FICA deductions, and other withholdings. Our free 2024 paycheck converter helps you understand exactly what to expect on your paycheck and how to optimize your deductions for maximum take-home pay.

Understanding Your Paycheck

Your paycheck represents the culmination of various calculations involving federal and state taxes, Social Security, Medicare, and voluntary deductions. Understanding each component helps you make informed decisions about your withholdings and take-home pay.

Gross pay is your total earnings before any deductions—the amount your employer agrees to pay you. Net pay (take-home pay) is what remains after all mandatory taxes and voluntary deductions are subtracted. For most workers, net pay ranges from 65% to 80% of gross pay, depending on tax bracket, state of residence, and benefit elections.

Federal Income Tax Withholding

Federal income tax is calculated using a progressive tax system where higher portions of income are taxed at higher rates. Your employer uses your W-4 form and IRS withholding tables to estimate the appropriate amount to withhold each pay period.

Tax RateIncome RangeTax Owed
10%$0 - $11,60010% of income
12%$11,601 - $47,150$1,160 + 12% of amount over $11,600
22%$47,151 - $100,525$5,426 + 22% of amount over $47,150
24%$100,526 - $191,950$17,168.50 + 24% of amount over $100,525
32%$191,951 - $243,725$39,110.50 + 32% of amount over $191,950
35%$243,726 - $609,350$55,678.50 + 35% of amount over $243,725
37%$609,351+$183,647.25 + 37% of amount over $609,350

The W-4 form determines how much federal income tax your employer withholds. The 2020 redesign eliminated allowances and now uses a more straightforward approach.

W-4 SectionPurposeImpact on Withholding
Step 1: Personal InformationFiling status selectionMarried typically withholds less than Single
Step 2: Multiple JobsFor multiple jobs or working spouseIncreases withholding for combined income
Step 3: DependentsClaim tax credits for dependentsReduces withholding ($2,000/child under 17)
Step 4(a): Other IncomeInterest, dividends, retirement incomeIncreases withholding
Step 4(b): DeductionsItemized deductions over standardDecreases withholding
Step 4(c): Extra WithholdingAdditional flat amount per paycheckIncreases withholding
W-4 Tip: If you consistently receive large refunds (over $1,000), you're essentially giving the government an interest-free loan. Adjust your W-4 to reduce withholding and increase take-home pay. Conversely, if you owe at tax time, increase withholding to avoid penalties.

FICA Taxes Explained

FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare. Unlike income tax, FICA is a flat tax rate applied to all wages up to certain limits.

TaxEmployee RateEmployer RateWage Base Limit
Social Security (OASDI)6.2%6.2%$168,600 (2024)
Medicare (HI)1.45%1.45%No limit
Additional Medicare0.9%0%Over $200,000 (single)
Total FICA7.65%7.65%-

Self-employed individuals pay both the employee and employer portions of FICA, totaling 15.3%. However, they can deduct half of self-employment tax as an income adjustment.

State Income Tax Overview

State income tax varies significantly across the United States. Nine states have no income tax, while others range from flat rates to highly progressive systems.

  • Alaska - No income tax; permanent fund dividend to residents
  • Florida - No income tax; popular for retirees and businesses
  • Nevada - No income tax; funded by gaming and tourism taxes
  • South Dakota - No income tax; low overall tax burden
  • Texas - No income tax; higher property taxes
  • Washington - No income tax; but has capital gains tax on high earners
  • Wyoming - No income tax; low population, mineral revenue
  • Tennessee - No income tax (as of 2021; previously taxed interest/dividends)
  • New Hampshire - No income tax (interest/dividend tax ended 2025)

Hawaii11.0%Pennsylvania3.07%
New Jersey10.75%Indiana3.15%
Oregon9.9%Michigan4.25%
Minnesota9.85%Colorado4.40%
Tax Residency Matters: You typically owe state income tax where you live, not where your employer is located. If you work remotely in a different state than your employer's headquarters, you generally pay taxes to your state of residence. Some states have reciprocity agreements that simplify this for cross-border workers.

Pre-Tax Deductions: Maximizing Take-Home Pay

Pre-tax deductions reduce your taxable income, providing immediate tax savings. Understanding and optimizing these deductions can significantly impact your net pay and long-term wealth.

Deduction Type2024 LimitTax Savings Example*Notes
401(k)/403(b)$23,000 ($30,500 if 50+)$5,520/yearEmployer match not counted toward limit
Traditional IRA$7,000 ($8,000 if 50+)$1,680/yearDeductibility phases out at higher incomes
HSA (Family)$8,300 ($9,300 if 55+)$1,992/yearTriple tax advantage; requires HDHP
HSA (Individual)$4,150 ($5,150 if 55+)$996/yearUnused funds roll over indefinitely
Healthcare FSA$3,200$768/yearUse-it-or-lose-it (small carryover allowed)
Dependent Care FSA$5,000$1,200/yearFor childcare/eldercare expenses
Commuter Benefits$315/month each$907/yearTransit and parking separate limits

*Tax savings assume 24% federal + effective state rate. Actual savings vary by tax bracket.

The Power of Pre-Tax: Contributing $500/month to a 401(k) costs much less than $500 in take-home pay. In the 24% federal bracket with 6% state tax, that $500 contribution only reduces take-home pay by about $350. You're investing $500 but only "spending" $350—an instant 43% return through tax savings.

Common Paycheck Mistakes to Avoid

Errors on paychecks are more common than you might think. Regular review helps catch and correct issues before they compound.

  • Incorrect hours: Verify regular and overtime hours match your records
  • Wrong pay rate: Especially after raises or job changes
  • Missing overtime: Ensure OT is calculated at 1.5x (or applicable rate)
  • Duplicate deductions: Benefits charged twice in error
  • Incorrect tax withholding: Compare to expected based on W-4
  • Missing reimbursements: Expense reimbursements should appear as non-taxable
  • Wrong benefit elections: Deductions not matching your selections
  • Garnishment errors: If applicable, verify correct amount and timing
Monthly Audit: Compare one paycheck per month to your expected calculations. Verify: (1) gross pay matches salary or hours × rate, (2) tax withholdings seem reasonable for your bracket, (3) benefit deductions match your elections, and (4) net pay calculation is correct. Report discrepancies to HR/payroll immediately.

Optimizing Your Paycheck

Strategic adjustments to your withholdings and deductions can significantly impact your financial situation throughout the year.

  • Maximize pre-tax contributions: 401(k), HSA, and FSA contributions reduce taxable income
  • Adjust W-4 withholding: If you receive large refunds, reduce withholding to keep more per paycheck
  • Review benefit elections: Ensure you're not over-insured or paying for unused benefits
  • Use commuter benefits: Pre-tax transit and parking saves 25-35% on commute costs
  • Consider Roth vs. Traditional: Roth 401k doesn't reduce taxes now but provides tax-free retirement income
  • You owed significant taxes last year and want to avoid penalties
  • You have substantial non-wage income (investments, side gigs)
  • You struggle to save and prefer a forced savings mechanism (tax refund)
  • Your income varies significantly and you want a safety buffer

Special Paycheck Situations

Bonuses, commissions, and other supplemental wages are often taxed differently than regular pay. The IRS allows two methods for withholding.

MethodHow It WorksWhen Used
Flat Rate (22%)22% federal withholding on entire bonusWhen bonus is separate from regular pay
Aggregate MethodCombined with regular pay, taxed as one paymentWhen bonus is on same check as salary
Bonus Withholding vs. Actual Tax: A 22% federal withholding on bonuses is just withholding, not your final tax rate. When you file your return, the bonus is taxed at your marginal rate. If you're in the 12% bracket, you'll get some back; if you're in the 32% bracket, you may owe more.

Non-exempt employees must receive overtime pay at 1.5 times their regular rate for hours over 40 per week. Some states (California) require daily overtime after 8 hours.

RSUs (Restricted Stock Units) and stock options have unique tax implications that appear on your paycheck.
