Making Sense of Your Paycheck: Gross Pay, Net Pay, and Everything Deducted in Between
| Social Security Tax Rate (Employee Share) | 6.2% of wages up to the annual wage base (IRS Publication 15 (Circular E)) |
| Medicare Tax Rate (Employee Share) | 1.45% on all wages (plus 0.9% above $200,000) (IRS Publication 15 (Circular E)) |
| Common Pay Frequencies | Weekly (52), Biweekly (26), Semimonthly (24), Monthly (12) |
| States with No State Income Tax | Texas, Florida, Washington, Nevada, Wyoming, South Dakota, Alaska (as of recent tax years) (State revenue department data) |
| Form Used to Set Federal Withholding | IRS Form W-4 (Employee's Withholding Certificate) (IRS.gov) |
| FSA vs. HSA Key Difference | HSA funds roll over indefinitely; most FSA funds must be used within the plan year (IRS Publication 969) |
Gross Pay vs. Net Pay: The Core Difference
Your gross pay is the total compensation your employer agrees to pay you before any deductions are applied — the number in your job offer or salary agreement. Your net pay is what actually lands in your bank account after federal taxes, state taxes, and benefit contributions are subtracted. The gap between these two figures can be significant, often 20–35% of gross pay for a typical full-time employee, which is why understanding the line items in between matters so much.
If you're building a budget, always start from net pay — that's your real spending power. For a broader look at managing your finances day to day, see Your Complete Roadmap to Everyday Financial Wellness.

Mandatory Deductions: What the Government Takes
These deductions are required by law. You cannot opt out of them, and your employer is legally obligated to withhold them on your behalf.
- Federal Income Tax Withholding: Based on your filing status and the allowances (or adjustments) you claim on IRS Form W-4. The IRS provides updated withholding tables each year. This is an estimate of your annual federal tax liability — you settle the final bill (or receive a refund) when you file your return.
- Social Security Tax (OASDI): A flat 6.2% of wages up to an annual wage cap, which the IRS adjusts periodically. Your employer matches this amount separately.
- Medicare Tax (HI): A flat 1.45% on all wages, with no cap. Employees earning above $200,000 individually also face an Additional Medicare Tax of 0.9%, which employers do not match.
- State Income Tax: Varies by state. Several states — including Texas, Florida, and Washington — levy no state income tax. Others use flat or progressive rates.
- Local/City Tax: Some municipalities in states like Pennsylvania, Ohio, and New York impose their own earned-income taxes on top of state taxes.
Gross Pay
Total compensation earned before any deductions are applied. This is the figure in your employment agreement or offer letter.
Net Pay
The amount deposited to your account after all mandatory and voluntary deductions are subtracted from gross pay. Also called take-home pay.
FICA
Federal Insurance Contributions Act taxes — the collective term for Social Security (6.2%) and Medicare (1.45%) withholding, both required by law for most employees.
W-4
IRS Employee's Withholding Certificate, which you complete when you start a job. It tells your employer how much federal income tax to withhold each pay period.
Pre-Tax Deduction
A benefit contribution subtracted from gross pay before income taxes are calculated, reducing your taxable wages and therefore the tax you owe.
HSA (Health Savings Account)
A tax-advantaged savings account paired with a high-deductible health plan, used for qualified medical expenses. Unused funds roll over year to year.
YTD (Year-to-Date)
Cumulative totals shown on your pay stub from January 1 through the current pay period. Useful for reconciling your W-2 at tax time.
Garnishment
A court-ordered withholding from your paycheck to satisfy a legal obligation such as child support, alimony, or certain debts.
Voluntary Deductions: Benefits and Pre-Tax Elections
These deductions appear on your stub because you (or your employer on your behalf) have elected them. Many reduce your taxable gross pay, which can lower the income tax you owe.
- Health Insurance Premiums: Your share of employer-sponsored medical, dental, and vision coverage. Premiums paid through a Section 125 cafeteria plan are deducted pre-tax.
- 401(k) / 403(b) Contributions: Traditional contributions reduce your current taxable income. Roth contributions come out after tax. Contribution limits are set by the IRS each year.
- Health Savings Account (HSA) / Flexible Spending Account (FSA): Both are pre-tax vehicles for qualified medical expenses. HSAs require enrollment in a high-deductible health plan (HDHP) and balances roll over; FSA funds generally must be used within the plan year.
- Life and Disability Insurance: Employer-sponsored group plans often deduct a small employee share each pay period.
- Dependent Care FSA: A pre-tax account for eligible childcare expenses, separate from a healthcare FSA.
If your income varies from paycheck to paycheck, these elections can feel harder to manage. Our article on managing money on a variable income covers strategies that work when earnings aren't predictable.
Other Common Line Items and What They Mean
A few more entries you might see on your stub:
- Garnishments: Court-ordered deductions for child support, alimony, or certain debts. These are mandatory and administered by your employer once a legal order is received.
- Union Dues: If you're a union member, dues may be deducted automatically per a collective bargaining agreement.
- YTD (Year-to-Date) Totals: Most stubs show cumulative totals for each line item since January 1. These are useful for verifying your W-2 at tax time and for tracking how close you are to contribution limits.
- Pay Period vs. Annual Rate: Your salary is divided across pay periods — weekly (52), biweekly (26), semimonthly (24), or monthly (12). Biweekly earners receive two "extra" paychecks in two months each year, which can affect monthly budgeting.
Understanding these terms is part of broader financial literacy — just as knowing depreciation and APR helps you evaluate car ownership costs, knowing your pay stub helps you evaluate your true take-home compensation. For debt-related terminology, see our debt glossary.
