Where to Put 401k Contributions on Tax Return

When filing your tax return, reporting your 401k contributions is crucial for maximizing your tax savings. Your 401k contributions reduce your taxable income, resulting in a lower tax bill. To report your contributions, use Form 1040 and the corresponding schedules. For traditional 401k plans, you report your contributions on Line 19 of Form 1040. These contributions are pre-tax and reduce your current year’s income. For Roth 401k plans, you report your contributions on Line 6 of Form 1040. Roth 401k contributions are made post-tax, meaning there’s no immediate tax benefit, but withdrawals in retirement are tax-free. Additionally, if you have made catch-up contributions for being age 50 or older, report those on Line 18 of Form 1040. Reporting your 401k contributions accurately ensures that you receive the maximum tax savings and avoids potential tax penalties.

Reporting 401(k) Contributions on Form W-2

Your 401(k) contributions are not reported on Form W-2. Instead, you need to report them on Form 1040, Schedule 1 (Form 1040), Line 32.

To report your 401(k) contributions on your tax return, you will need the following information:

  • Your total 401(k) contributions for the year
  • Your employer’s 401(k) plan number

You can find your total 401(k) contributions on your Form W-2, Box 12, Code D.

You can find your employer’s 401(k) plan number on your Form 1099-R, Box 2a.

Once you have this information, you can report your 401(k) contributions on your tax return as follows:

  1. On Form 1040, Line 32, enter the total amount of your 401(k) contributions for the year.
  2. On Schedule 1 (Form 1040), Line 32, enter your employer’s 401(k) plan number.

Your 401(k) contributions will be deducted from your gross income, which will reduce your taxable income.

Including 401(k) Deductions on Schedule 1

To reduce your taxable income if you contributed to a traditional 401(k) plan in 2022, you may deduct the contributions on your federal income tax return. Here’s how to do it:

  • Gather your 401(k) contribution information, including the total amount contributed for the year.
  • On your tax return, complete Schedule 1 (Form 1040), Adjustments to Income.
  • Under the “Retirement Savings Contributions” section, find line 11, “Traditional and Roth IRA contributions” (code V).
  • Enter the total amount of traditional 401(k) contributions that were made pre-tax.

The total amount of traditional 401(k) contributions you made during the year reduces your taxable income. This lowers the amount of taxes you owe.

Here’s an example of how to include 401(k) deductions on Schedule 1:

LineDescriptionAmount
11Traditional and Roth IRA contributions (code V)$5,000

In this example, the taxpayer contributed $5,000 to their traditional 401(k) plan in 2022. By including this amount on line 11 of Schedule 1, they reduce their taxable income by $5,000.

Reporting Traditional 401(k) Contributions on Line 16

Traditional 401(k) contributions reduce your current year’s taxable income, potentially lowering your tax bill. Follow these steps to report them on your tax return:

  • Gather your paperwork: Obtain your Form W-2 and any 1099-R forms that show your 401(k) contributions.
  • Locate Line 16 on Form 1040: This line is labeled “Traditional IRA and Roth IRA Contributions, and Qualified Retirement Plan Distributions Not Taxable in 2023.”
  • Enter your 401(k) contributions: In the box labeled “Traditional and Roth IRA Contributions,” enter the total amount of your pre-tax 401(k) contributions for the year.
  • Report excess contributions: If you made excess contributions, they will be reported on Line 19 of Form 1040. You may incur a penalty if you fail to report this information.

To report your traditional 401(k) contributions on your tax return, you will need to enter the amount on line 16 of Form 1040 or 1040-SR.

Reporting Roth 401(k) Contributions

Roth 401(k) contributions are post-tax deductions from your paycheck. You pay taxes on this money now, but you won’t when you withdraw it in retirement.
