Gross wages are an employee’s total compensation earned for a pay period, before any tax withholding, benefit deduction or garnishment comes out of it. For an hourly employee that is every hour actually worked at the rates that apply to it, with the overtime premium already inside the figure; for a salaried employee it is the share of the annual salary the period covers. Gross pay, gross earnings and gross salary name the same amount.
Gross Wages Is a Base, and the Base Changes With the Tax
Federal tax law does not use one definition of wages, so one gross figure on a payroll register is a starting point rather than an answer.
For income tax withholding, the Internal Revenue Code defines wages as all remuneration for services performed by an employee for his employer, including the cash value of all remuneration paid in any medium other than cash, subject to a list of exclusions (26 U.S.C. 3401(a)).
For FICA, the Social Security and Medicare taxes, the Code gives wages a second definition with its own exclusion list: all remuneration for employment, including the cash value of all remuneration paid in any medium other than cash (26 U.S.C. 3121(a)). The first exclusion is the cap, and it is narrower than it reads. It applies only in the case of the taxes imposed by sections 3101(a) and 3111(a), the old-age, survivors and disability insurance taxes, and it removes only the remuneration an employer pays an individual after that same employer has already paid the contribution and benefit base for the calendar year (26 U.S.C. 3121(a)(1)). Nothing caps the Medicare side.
The two exclusion lists disagree, and one disagreement reaches every payroll running a retirement plan. Nothing in any paragraph of the FICA list other than that cap excludes an employer contribution under a qualified cash or deferred arrangement to the extent it is not included in gross income, or a designated Roth contribution (26 U.S.C. 3121(v)(1)(A)). An elective deferral, the pay an employee routes into such an arrangement instead of taking it in cash, therefore leaves the FICA base alone.
Where the Difference Lands on Form W-2
The wage statement reports those bases side by side rather than reconciling them, which is how three boxes on one Form W-2 carry three numbers for one employee.
Box 1 shows the total taxable wages, tips and other compensation paid during the year, and the instructions say not to include elective deferrals such as employee contributions to a section 401(k) or 403(b) plan, with a narrow exception for section 501(c)(18) contributions (IRS, General Instructions for Forms W-2 and W-3).
Box 3 shows the total wages paid, before payroll deductions, subject to employee social security tax, and it is the capped one. Elective deferrals are reported there even though they are not includible in box 1, and the total of boxes 3 and 7, social security wages plus social security tips, cannot exceed $184,500, the 2026 maximum social security wage base (IRS, General Instructions for Forms W-2 and W-3). That cap is set outside the tax code and moves each year with the national average wage index, and for earnings in 2026 the contribution and benefit base is $184,500 (SSA, Contribution and Benefit Base).
Box 5 shows Medicare wages and tips, the same wages as box 3 except that there is no wage base limit. The instructions work the case themselves: an employee paid $199,750 in wages has $184,500 entered in box 3 and $199,750 entered in box 5 (IRS, General Instructions for Forms W-2 and W-3).
Overtime Enters Gross Wages at the Regular Rate
For hourly staff, the stated hourly rate does not settle the composition of the figure. The rate the overtime premium is measured against cannot be left to a declaration by the parties as to what is to be treated as the regular rate for an employee, and section 7(e) of the Fair Labor Standards Act, the federal wage and hour law, requires inclusion in that rate of all remuneration for employment paid to, or on behalf of, the employee, except the payments the subsection specifically excludes (eCFR, section 778.108, The regular rate).
That rate is computed, not quoted. The regular hourly rate of pay of an employee is determined by dividing his total remuneration for employment, except statutory exclusions, in any workweek by the total number of hours actually worked by him in that workweek for which such compensation was paid (eCFR, section 778.109, The regular rate is an hourly rate). A nondiscretionary bonus earned in a workweek raises the numerator of that division, so it raises the regular rate above the stated hourly rate, and a premium computed on the stated rate understates gross wages. The entitlement those sections measure, the premium a covered employee must receive for hours beyond the standard workweek, is taken up in in-house versus outsourced accounting.
A Worked Example on One Pay Period
Say an hourly employee works a single weekly period on the inputs below, on a plan that takes elective deferrals as a fixed share of gross wages. Amounts subtracted are shown in parentheses.
INPUTS
Hours worked in the workweek 45
Stated hourly rate 30.00
Nondiscretionary bonus earned in the week 90.00
Elective deferral rate 5%
Federal income tax withheld (an assumed input) 152.00
THE REGULAR RATE
Straight-time pay 45 x 30.00 1,350.00
Bonus 90.00
Total remuneration 1,440.00
Regular rate 1,440.00 / 45 32.00
GROSS WAGES
Total remuneration 1,440.00
Overtime hours 45 - 40 5
Overtime premium 5 x (32.00 / 2) 80.00
Gross wages 1,520.00
THE THREE BASES FOR THIS PERIOD
Income tax withholding 1,520.00 - 76.00 1,444.00
Social security wages 1,520.00
Medicare wages 1,520.00
GROSS TO NET
Gross wages 1,520.00
Elective deferral 5% x 1,520.00 (76.00)
Social security 6.2% x 1,520.00 (94.24)
Medicare 1.45% x 1,520.00 (22.04)
Federal income tax withheld (152.00)
Net pay 1,175.72The two FICA rates in that arithmetic are the statutory employee rates, set out with the employer’s matching charge in federal income tax liability, and the example assumes year-to-date wages far below the wage base cap, so nothing in it is capped. Withholding is an input to the example rather than a result, because every employer making payment of wages deducts and withholds a tax determined in accordance with tables or computational procedures prescribed by the Secretary (26 U.S.C. 3402(a)(1)).
Four figures come out of that one period. Gross wages already has the overtime premium inside it, the income tax base is gross wages less the deferral, both FICA bases equal gross wages because the deferral never left them, and net pay is the only one the employee sees land in an account.
What Gross Wages Is Not
It Is Not Net Pay
Net pay is gross wages less every withholding and deduction, so gross wages is the input and net pay is the result. The wider gross versus net idea in accounting, and the order the subtractions run in on the income statement, are set out in net income.
It Is Not the Employer’s Cost of Employment
The employer’s own payroll taxes sit above gross wages rather than inside them, and the statute is explicit about who bears them. The old-age, survivors and disability insurance tax and the hospital insurance tax are each imposed on every employer as an excise tax, with respect to having individuals in his employ, and only measured as a percentage of the wages paid (26 U.S.C. 3111). The employee never earns that money, so it never appears in gross wages, and grossing pay up to a fully loaded seat cost is a separate calculation worked through in the offshore accounting cost savings calculator.
Common Questions
For an hourly employee, multiply the hours actually worked by the rates that apply to them, then add the overtime premium computed on that workweek’s regular rate. For a salaried employee, take the share of the annual salary the period covers, and where the period is a partial one the arithmetic and the limits on it are in prorated. Add every other item of remuneration paid for the period after that, because both statutory definitions start from all remuneration and take out only what they name.
Accountably places trained offshore accountants and tax preparers inside US CPA and EA firms, and a firm can run a real block of its own payroll reconciliation and close work through a trial task before anything client facing depends on it.
