Definition

Net pay: is the amount an employee actually receives on payday after all taxes and deductions are subtracted from gross pay. It is often called take-home pay, and it is the figure that lands in the employee's bank account or on the paycheck.

Key takeaways

  • Net pay equals gross pay minus pre-tax deductions, payroll taxes, and post-tax deductions.
  • The order matters: pre-tax deductions come out first and lower the wages that get taxed.
  • Two employees with the same salary can take home very different amounts because of W-4 choices, benefits, and state taxes.
  • Employees judge payroll accuracy by net pay, so unexplained changes create the most support tickets.

How net pay works

Payroll software works from the top of the stub to the bottom. It starts with gross pay, subtracts pre-tax deductions such as traditional 401(k) deferrals, Section 125 health premiums, and HSA or FSA contributions, then calculates taxes on what remains. Federal income tax withholding comes from the employee's Form W-4 and the IRS tables in Publication 15-T. Social Security and Medicare follow the FICA rates. State and local income taxes depend on where the employee lives and works.

After taxes come post-tax deductions: Roth 401(k) deferrals, union dues, charitable gifts, and wage garnishments. What is left is net pay.

One nuance: pre-tax doesn't mean the same thing for every tax. A traditional 401(k) deferral reduces federal income tax wages but not Social Security and Medicare wages. A Section 125 premium reduces both. That is why boxes 1, 3, and 5 on a W-2 often show three different numbers (IRS Publication 15 (Circular E), Employer's Tax Guide).

Net pay example

Jordan earns $65,000 a year, paid biweekly, and lives in a state with a flat income tax. Here is a typical paycheck. The federal and state withholding amounts are illustrative, since they depend on the W-4 and state form.

Gross pay$2,500.00
Traditional 401(k), 5%minus $125.00
Medical premium (Section 125)minus $90.00
Social Security, 6.2% of $2,410minus $149.42
Medicare, 1.45% of $2,410minus $34.95
Federal income tax (from W-4)minus $190.00
State income taxminus $80.00
Net pay$1,830.63

Jordan takes home about 73% of gross. Notice that Social Security and Medicare were figured on $2,410, because the medical premium is exempt from FICA but the 401(k) deferral isn't.

Why net pay matters for employers

Net pay is where trust is won or lost. An employee rarely checks how box 3 of a W-2 was built, but they notice immediately when their deposit drops by $40. Health costs are a frequent cause: the average worker contribution for family coverage reached $6,850 a year in 2025, according to the KFF 2025 Employer Health Benefits Survey, and premium changes at open enrollment show up first as lower net pay.

Clear stubs and a short explanation before any change, like a new benefits year or a tax update, cut payroll questions sharply. If a mistake does happen, our payroll error correction email template helps you explain the fix.

Common net pay mistakes to avoid

Applying 401(k) deferrals to FICA wages

Traditional 401(k) deferrals still owe Social Security and Medicare. Only income tax wages go down.

Taking garnishments from gross pay

Federal garnishment limits are based on disposable earnings, which is pay after legally required deductions, not gross pay.

Ignoring local taxes for remote staff

Employees who move to a city with a local income tax, such as Philadelphia or several Ohio cities, need new withholding set up.

Changing deductions without notice

Deductions that aren't required by law usually need the employee's written authorization, and some states require advance notice.

Net pay: questions people also ask

What is the difference between gross pay and net pay?
Gross pay is total earnings before anything is taken out. Net pay is what remains after taxes, benefits, retirement contributions, and other deductions. Net pay is always the smaller of the two unless there are reimbursements added back.
Why did my net pay go down when my salary didn't change?
The most common reasons are a new benefits plan year, a higher retirement deferral, a W-4 change, a garnishment, or crossing a tax threshold. Compare two pay stubs line by line to find the difference.
How much of gross pay is net pay on average?
Many US employees take home roughly 70% to 80% of gross pay, but the share varies widely with income, state, filing status, and benefit elections. High earners in high-tax states take home less.
Can an employer pay net pay in cash?
Federal law allows cash, check, or direct deposit. Several states restrict mandatory direct deposit or pay cards, so check state rules before requiring a payment method.
Are expense reimbursements part of net pay?
Reimbursements under an accountable plan are added after taxes and aren't wages, so they increase the deposit without increasing taxable income. They should appear as a separate line on the pay stub.
