Does Box 1 W2 Include 401k Contributions

Box 1 of your W-2 form, which shows your total wages and salaries, typically includes 401(k) contributions made on a pre-tax basis. These contributions are deducted from your paycheck before taxes are taken out, reducing your taxable income. However, 401(k) contributions made on an after-tax basis are not included in Box 1. Instead, they are reported in Box 12 with code D.

Understanding the Purpose of Box 1 on Form W-2

Box 1 on the Form W-2, titled “Wages, Tips, Other Compensation,” serves as a crucial field that reports the total taxable wages and other forms of compensation an employee earned during the tax year. This information is essential for determining the employee’s federal and state income tax liability.

401(k) contributions, however, are not included in Box 1. They are reported in Box 12, designated as “Code D” or “Code DD,” depending on the type of plan.

401(k) Contributions and Taxability

Your W-2 form reports your wages and other compensation received from your employer during the tax year. Box 1 of the W-2 shows your total wages, which includes your base salary, bonuses, commissions, and other forms of taxable income.

401(k) contributions are not included in Box 1 of your W-2. This is because 401(k) contributions are made on a pre-tax basis, meaning they are deducted from your paycheck before taxes are calculated. As a result, 401(k) contributions reduce your taxable income, but they are not considered part of your wages.

To summarize, the answer to the question “Does Box 1 W2 Include 401k Contributions?” is no. 401(k) contributions are not included in Box 1 of your W-2 because they are made on a pre-tax basis and reduce your taxable income.

Retirement Account Reporting on W-2
