How Paycheck Taxes Work | Step-by-Step Gross-to-Net Withholding Guide 2026

The Step-by-Step Paycheck Reduction Pipeline

When you receive a paycheck, your earnings move through seven distinct stages before net pay is deposited:

1

Gross Pay

The total amount earned before any deductions or taxes. This is your contracted hourly wage multiplied by hours worked, or your annualized salary divided by pay periods.

2

Pretax Deductions

Eligible employee contributions (such as traditional 401(k), 403(b), HSA, FSA, and health insurance) that are subtracted before taxable wages are calculated.

3

Federal Withholding

Federal income tax withheld by your employer according to your Form W-4 elections and 2026 IRS withholding tables (Publication 15-T).

4

Social Security & Medicare

These are statutory FICA taxes. For 2026, employee Social Security withholding is 6.2% up to the $184,500 wage base limit. Medicare withholding is 1.45% with no wage limit, plus 0.9% Additional Medicare for wages above $200,000.

5

State and Local Taxes

Where applicable, state individual income taxes (flat or progressive) and municipal wage withholdings (such as city or county taxes) are deducted.

6

Other Payroll Deductions

Post-tax deductions, such as Roth 401(k) contributions, union dues, life insurance premiums, charitable payroll gifts, or court-ordered wage garnishments.

7

Estimated Net Pay

The take-home amount remaining after all tax withholdings and deductions have been processed. This is what deposits directly into your bank account.

📖 A Simple Way to Read Your Result

Follow the sequence of reductions to understand any unexpected paycheck change:

Start with gross pay. Then look at federal tax, FICA and state or local tax. Finally, review any other deductions. What remains is your estimated net pay or take-home pay. This sequence helps identify what changed when your paycheck is higher or lower than expected.

Frequently Asked Questions

Taxes and payroll deductions reduce gross earnings before the final amount reaches you.

No. Social Security and Medicare are FICA payroll taxes. Federal income tax withholding is a separate payroll withholding item.

Payroll systems can include elections, benefits, local taxes and employer-specific assumptions that are not represented in a simple public calculator.

Expanded Reader Guidance

💡 A paycheck is a sequence of reductions, not one tax

The path from gross pay to take-home pay can include federal income tax withholding, Social Security, Medicare, state or local taxes where applicable, and other deductions. Looking at those pieces separately makes the result easier to understand and easier to compare with a real pay stub.

💡 Withholding is not the same as final tax liability

Payroll withholding is an amount set aside during the year. Your eventual tax return is a separate calculation. This distinction matters because a paycheck calculator is designed to explain an individual payment, not determine your final annual tax position.

💡 The practical question to ask when the result changes

When net pay changes, start by asking which component changed. Gross pay may have changed, the pay frequency may be different, withholding elections may have changed, or another deduction may have appeared. Breaking the result into components turns a confusing number into a solvable question.
