Per IRS guidelines, your employer doesn't include your pre-tax contributions in your taxable income because your 401(k) contributions are tax-deductible. Instead, they report your contributions in boxes 1 and 12, respectively, of your form W-2.
If you have a 401(k) or individual retirement account (IRA), you might be wondering what you are required to report on your taxes. Luckily, you typically don't need to report your 401(k) contributions, 401(k) or IRA balances, or even investment returns to the Internal Revenue Service (IRS).
Unless you're a business owner, you won't claim your 401(k) contributions as tax deductible when you fill out your Form 1040. Instead, the money is taken out of your paycheck before federal taxes on your income are figured. This is how you save on taxes today.
When it's time to prepare tax returns, distributions show up in two important places: On the business side, distributions show up on the balance sheet section of your tax return (total distributions since the business started) and in Section M-1, which shows distributions that have been made throughout the year.
Any money you withdraw from your 401(k) is considered income and will be taxed as such, alongside other sources of taxable income you may receive. As with any taxable income, the rate you pay depends on the amount of total taxable income you receive that year.
Box 12 - Compensation and Benefits
This box indicates compensation or benefit by code. These codes include Elective deferrals for a 401(k) retirement plan, cost of employer-sponsored health coverage, and taxable cost of group-term life insurance.
Required to be filed annually
IRS/DOL: By the last day of 7th month after the end of the plan year. Reports wages and the amount of elective deferrals for a 401(k) plan. Employees: By January 31 following the calendar year.
If you have a 401(k) or TSP through your employer, your contribution is reported in Box 12 of your W-2 with the letter code D. Because your contribution is included in your W-2, do not re-enter it in the retirement section.
Box 14 is used to report amounts that don't belong in other boxes on Form W-2. Employers can use it to report additional tax or income information for filing or informational purposes. Some employers use box 14 to report amounts deducted for State Disability Insurance taxes or union dues that may be tax deductible.
You'll receive a Form 1099-R Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, etc. from the payer of your 401(k) distribution. A copy of that form is also sent to the IRS.

These deferred wages (elective deferrals) are generally not subject to federal income tax withholding at the time of deferral, and they are not reflected as taxable income on your Form 1040, U.S. Individual Income Tax Return PDF.
The IRS requires that Form 1099-R be sent by January 31 of the year following any 401(k) distribution amount of $10 or more.
Contributions to a traditional 401(k) are made with pre-tax dollars—meaning the money goes into your retirement account before it gets taxed. With pre-tax contributions, every dollar you save will reduce your current taxable income by an equal amount, which means you'll owe less in income taxes for the year.
Your elective contributions may also be limited based on the terms of your 401(k) plan and are reported as an information item in box 12 of your Form W-2.
Health Insurance Cost on W-2 - Code DD. Many employers are required to report the cost of an employee's health care benefits in Box 12 of Form W-2 Wage and Tax Statement, using code "DD" to identify the amount. This amount is reported for informational purposes only and is NOT taxable.
Once you start withdrawing from your traditional 401(k), your withdrawals are usually taxed as ordinary taxable income. That said, you'll report the taxable part of your distribution directly on your Form 1040 for any tax year that you make a distribution.
The National Registry of Unclaimed Retirement Benefits is a good place to start. By entering your Social Security number, you can quickly see if there are any unclaimed 401(k) funds that belong to you.
While there is no legal time limit on how long an employer or a former employer can freeze your 401(k) account, companies usually try to rectify these situations as soon as possible. Keep in mind that even during the blackout period, your money stays invested, and your account can continue to grow.
A 401(k) is a tax-advantaged retirement savings plan. Named after a section of the U.S. Internal Revenue Code, the 401(k) is an employer-provided, defined-contribution plan.1 The employer may match employee contributions; with some plans, the match is mandatory.
To report the tax on early distributions, you may have to file Form 5329, Additional Taxes on Qualified Plans (Including IRAs) and Other Tax-Favored Accounts PDF. See the Form 5329 instructions PDF for additional information about this tax.
By age 50, you should have six times your salary in an account. By age 60, you should have eight times your salary working for you. By age 67, your total savings total goal is 10 times the amount of your current annual salary. So, for example, if you're earning $75,000 per year, you should have $750,000 saved.
As a general rule, if you withdraw funds before age 59 ½, you'll trigger an IRS tax penalty of 10%. The good news is that there's a way to take your distributions a few years early without incurring this penalty. This is known as the rule of 55.
