Short answer
Gross pay is what an employee earns before deductions; net pay is what the employee receives afterward. The gap consists of tax withholding and other amounts deducted—not just income tax. Net pay is also called take-home pay. 1

| Question | Gross pay | Net pay |
|---|---|---|
| What does it measure? | Earnings before deductions | Amount received after deductions |
| Where is it in the calculation? | Starting amount | Result after subtraction |
| Other terminology here? | Gross wages | Take-home pay |
These are stages of payroll, rather than different kinds of compensation. 1 2
What each thing is
Gross pay describes earnings, while net pay describes the remainder available through payroll after deductions. Publication 4268 defines gross wages for the pay period as total wages and uses that figure to begin calculating withholding and net payroll. The comparison therefore needs a matching pay period. 1 2
Key differences
The basic relationship is gross pay − deductions = net pay. The IRS identifies Social Security, Medicare, income tax withholding, and other withheld amounts as components of the difference. Its payroll guide also lists possible deductions such as insurance, charitable items, and union dues. The gap need not be entirely taxes. 1 2
How to tell them apart
On a pay stub, look for the earnings total before deductions and the amount remaining after the listed deductions. Compare current-period figures with current-period figures: the IRS guide describes stubs with separate current-period and year-to-date columns. This rule identifies payroll amounts; it does not establish what belongs in a tax-return wage field. 2
Where they overlap
Both figures describe the same employee’s payroll, from different points in the calculation. They can be numerically equal in a hypothetical pay period with no deductions. Equal amounts would not erase the distinction: gross still measures earnings before subtraction, and net still measures the result afterward. 1
Edge cases
A zero paycheck does not necessarily mean zero earnings. In Publication 4268’s tipped-worker illustration, withholding associated with regular wages and reported tips exhausts the regular paycheck. That example shows why net paycheck and total earnings can diverge sharply; its withholding amounts are explicitly illustrative, not current tax tables. 2
Why the distinction exists
Separating gross from net makes the payroll calculation visible: it distinguishes earnings from amounts withheld and the remainder paid out. Employers send withheld federal taxes to the federal government, while the payroll guide describes remitting other deductions to their appropriate recipients. Those amounts are withheld rather than received as take-home pay. 1 2
Common misconceptions
Gross pay should not automatically be equated with W-2 taxable wages. The supplied guide’s specialized tribal fishing-rights discussion includes exempt wages that it says should be omitted from Form W-2. That supports a limited counterexample—not a general formula for reconciling every employee’s gross pay with W-2 wages. 2
Examples
Hypothetical case 1: An employee earns $1,000 and has $180 in total deductions. Gross pay is $1,000; net pay is $820.
Hypothetical case 2: Two employees each earn $1,000, but deductions total $100 for one and $250 for the other. Their gross pay matches, while net pay is $900 and $750. These are arithmetic illustrations, not tax estimates. 1
