If an employee elected to contribute to a pre-tax retirement plan, their W-2 Box 1 wages are likely lower than their Box 3 wages. An employee's elected retirement plan contributions are not subject to federal income taxes. However, these contributions are subject to Social Security and Medicare taxes.
Box 3 shows your total wages subject to the Social Security tax. This figure is calculated before any payroll deductions which means that the amount in box 3 could be higher than the number reported in box 1, as in my example.
Box 1 (Wages, Tips and Other Compensation) represents the amount of compensation taxable for federal income tax purposes while box 3 (Social Security Wages) represents the portion taxable for social security purposes and box 5 (Medicare Wages) represents the portion taxable for Medicare tax purposes.
If your Box 1, W-2 amount is less than your salary, it is because you have pre-tax deductions from your salary under one or more employer plans. If you are not sure about your Box 1 amount, your payroll department can provide the details of the calculation of your Box 1 amount.
Income for Social Security purposes includes payroll deductions, but Social Security taxes only apply to the first $128,400 of gross earnings for tax year 2018. Therefore, for low wage earners, box 3 is often higher than box 1, and for high wage earners, box 3 is often lower than box 1.
Some pre-tax deductions reduce your taxable income (box 1) and your social security income (box 3). Other pre-tax deductions only reduce your taxable income (box 1). If you have a deduction that only reduces your taxable income then the amounts in box 1 and box 3 will be different.
Why is My W-2 Different from My Salary? The compensation may be different on a W-2 vs a final pay stub, but here's why. Your salary is a gross dollar amount earned before taxes and deductions. Meanwhile, your Form W-2 shows your taxable wages reported after pre-tax deductions.
The most common reason for this discrepancy is the impact of pretax deductions, such as Section 125 health-related deductions or retirement plans like a 401(k). These pretax deductions reduce the amount of taxable wages reported on a W2.
Box 1 "Wages, tips, other compensation": This is federal, taxable income for payments in the calendar year. The amount is calculated as YTD earnings minus pre- tax retirement and pre-tax benefit deductions plus taxable benefits (i.e., certain educational benefits).
Box 3: Social Security wages. Box 3 reports the total amount of wages subject to the Social Security tax. For 2010, the Social Security tax is assessed on wages of $106,800 or less. This limit is called the Social Security wage base.
The most common questions relate to why W-2 Wages differ from your final pay stub for the year, and why Federal and State Wages per your W-2 differ from Social Security and Medicare Wages per the W-2. The short answer is that the differences relate to what wage amounts are taxable in each case.
Call the IRS toll free at 800-829-1040 or make an appointment to visit an IRS Taxpayer Assistance Center (TAC). The IRS will send your employer a letter requesting that they furnish you a corrected Form W-2 within ten days.
Usually, the difference relates to what wage amounts are taxable in each case. In certain States, items that can be excluded from federal wages (for instance contributions to some types of retirement accounts) are not deducted from state salaries.
Box 1: Wages, tips, other compensation
If you see that this figure is higher or lower than other wages on your W-2, that's okay. If your Box 1 wages are lower than your Box 3 wages, it may be because you have pre-tax benefits that are exempt from federal income tax, but not Social Security tax.
Reasons Why You Might Not Have Paid Federal Income Tax

Gross pay is what employees earn before taxes, benefits and other payroll deductions are withheld from their wages. The amount remaining after all withholdings are accounted for is net pay or take-home pay.
You can find your AGI on Box No 1 of your W2, this income is a combination of your Wages, Tips, Compensation and also addition of boxes of 2 to 14.
When you do your taxes, you use Box 1 to fill in line 7 (wages) of your tax return. Your tax bill is figured on that number. When you make a pre-tax 401(k) contribution, that amount does not show up in Box 1. Your employer's contribution, whether it be a match or other contribution, also is not included in Box 1.
Gross income includes all income you receive that isn't explicitly exempt from taxation under the Internal Revenue Code (IRC). Taxable income is the portion of your gross income that's actually subject to taxation. Deductions are subtracted from gross income to arrive at your amount of taxable income.

The amount in Box 1 will generally be the “YTD Gross” under the Summary section of your final earnings statement, minus any pre-tax deductions such as health/dental/vision insurance, flexible spending accounts and retirement and tax deferred savings plans, etc.

Box 5 reports the amount of wages subject to the Medicare Tax. There is no maximum wage base for Medicare, so the amount showing in Box 5 may be larger than the amount showing in Box 1. It is quite common for Boxes 3 and 5 to be higher than Box 1.
