W-2 vs Last Pay Stub: What’s the Difference?

The Difference Between a W-2 and Final Pay Stub

As fall ends and winter begins, employers begin preparing for the upcoming tax season. One question that many employers and HR directors get asked each year revolves around the W-2 vs last pay stub. When employees receive their W-2s each year, they notice a difference between their last pay stub and W-2 form.

Regardless of whether you’re new to payroll taxes or you’re a seasoned payroll veteran, this topic can be confusing to navigate. We’ve created this article so you can understand and explain the differences in gross pay vs W-2 wages to your employees.

Why is My W-2 Different from My Salary?

The compensation may be different on a W-2 vs a final pay stub, but there’s a good reason. Your salary is a gross dollar amount earned before taxes and deductions are taken out. Meanwhile, your Form W-2 shows your taxable wages reported after pre-tax deductions. Pre-tax deductions include employer-provided health insurance, dental insurance, life insurance, disability insurance, and 401k contributions. That’s why your W-2 doesn’t match your last pay stub.

Unless you opt out of pre-tax deductions, your salary amount will almost always be higher than wages reported on your W-2. To clarify which pre-tax deductions you are opted in to, check Box 1 of your W-2. If you are confused about your Box 1 deductions, speak to your HR manager, as they can help clarify details related to these withholdings.

Is a W-2 the Same as a Pay Stub?

No, a W-2 is not the same as a pay stub. A W-2 form, also known as a Wage and Tax Statement, is a required document that an employer must send to employees each year. Once an employee elects their preferred withholdings like healthcare and 401(k) contributions, the employer must send a receipt of that information to the Internal Revenue Service (IRS) for reporting purposes. Think of your W-2 as net earnings pay stub.

A pay stub outlines the details of an employee’s gross wages each pay period. While it is not required for employers to send pay stubs to employees, the Fair Labor Standards Act does make employers track hours employees have worked. A paystub is typically attached to an employee’s physical paycheck. Certain payroll providers also offer paperless payroll so employees can also access paystubs online.

Reasons Why the Gross Amount on Your End-of-Year Pay STub May Be Different Than the Amount on Your W-2

APS receives many questions during tax season, and the one that comes up most often is, “Why doesn’t my W-2 match my pay stub?” or “Why doesn’t my W-2 match my salary?” It is typical for gross taxable wages on an employee’s final pay stub of the year to differ from the amount shown on their Form W-2. This difference is a result of the following reasons:

1. Year-End Pay Stubs Include Non-Taxable Income Items

Examples of non-taxable income items include reimbursements for mileage or other types of non-taxable expenses. These non-taxable items are paid back during payroll runs. As a result, the gross wages on an employee’s pay stub often differ from the Boxes 1, 3, 5, and 16 wages on the W-2 because these non-taxable items will lower gross taxable wages.

Example

Mary’s gross wages are $30,000 but over the course of the year, she received $2,000 towards a non-taxed car allowance. Mary’s taxable W-2 wages will be $28,000. ($30,000 – $2000 = $28,000).

2. Company-Sponsored Retirement Plan Participation

Company-sponsored retirement plans like a 401(k)s reduce taxable federal and state wages only. They are reported in Boxes 1 and 16, respectively. If you contribute to a retirement plan, the compensation on your end-of-year pay stub vs your W-2 will be different.

Example

Sally’s gross wages are $30,000 but over the course of the year, she contributed $3,000 towards her 401(k) retirement. Sally’s federal and state W-2 wages will be $27,000. ($30,000 – $3000 = $27,000).

3. Company Health Insurance is a Pre-Tax Deduction

Company health insurance is the most common reason that your last pay stub does not match your W-2. If your company offers pre-tax health insurance and you have participated, then the taxable wages in Boxes 1, 3, 5, and 16 will be lower than the amount of the pre-tax health insurance deduction. Pre-tax deductions will lower the gross wages by the annual amount of the deduction.

Example

John’s gross wages are $30,000 but over the course of the year, he contributed $2,000 to a pre-tax health insurance deduction. John’s taxable W-2 wages will be $28,000 ($30,000 – $2,000 = $28,000).
