Can You Deduct 401K Savings From Your Taxes?

Tax Deductions and Credits Mom Trying To Work While Baby Is Distracting Her

Contributions you make to your 401(k) plan can reduce your tax liability at the end of the year as well as your tax withholding each pay period. However, you do not actually take a tax deduction on your income tax return for your 401(k) plan contributions. This is because you receive the benefit of a tax deduction every time you make a contribution with pre-tax dollars.

Contributions to Your 401(k)

The 401(k) plan contributions you elect to make come directly out of your salary. Since the contributions are made with pre-tax dollars, your employer does not include these amounts in your taxable income for the year. At the end of the year, when you receive your W-2 form that shows your earnings, you will notice that your wages subject to federal income tax are lower because of your 401(k) plan contributions. Since the wages are not counted in your taxable income to begin with, you do not take a deduction when you file your return. However, when you prepare your tax return, it’s possible to calculate how much income tax your 401(k) contributions saved you. For example, if you contribute $8,000 to your 401(k) during the year and that amount would be taxed in the 25 percent bracket if included in taxable income, then your tax savings is $2,000.

Increase in Your Take-Home Pay

Your 401(k) plan contributions also reduce the amount of your income tax withholding. Each time you get paid, your employer withholds money for your federal income taxes based on your expected taxable income. However, if you make 401(k) plan contributions, the amount of money subject to withholding will decrease since your taxable income is less than your actual salary. The result is more money in your take-home pay each pay period.

The Saver’s Tax Credit

In addition to the tax savings available for your contributions to a 401(k), the IRS also offers the Saver’s Credit if your Adjusted Gross Income (AGI) doesn’t exceed certain maximums. This credit offers a dollar-for-dollar reduction of your income tax bill. In 2017, single taxpayers whose AGI didn’t exceed $18,500 can receive a credit up to $1,000 and married taxpayers with an AGI of $37,000 or less can receive up to $2,000. If your AGI doesn’t exceed these thresholds, you are at least 18 years of age and are not a dependent of another taxpayer, then you can decrease your tax liability with the Saver’s Credit.

Misconceptions About 401(k) Contributions

The contributions that you make to a 401(k) plan only reduce your income taxes, not your Social Security and Medicare taxes. These two taxes only apply to your earned income, but you do not get to claim any deductions before these taxes are assessed. For example, if your gross wages for the month are $2,500 and you contribute $400 to your 401(k) plan from it, there is withholding on the full $2,500 for Social Security and Medicare even though for federal income tax purposes, there is withholding on $2,100.

When you get ready to file your 2017 taxes remember you can still contribute up to $5,500 ($6,500 if you are 50 and older) to your IRA by the tax deadline and you may be able to get a tax deduction on your 2017 taxes.  Just remember to tell your retirement account administrator that your contribution is for 2017 and not  2018.

  1. I don’t know where to ask about this. i work construction and have a union 401k. some employers are smarter than others and get it right on the first paycheck. My current employer took several weeks to figuret out just how to make the deduction in their computer system. Not many carpenters know we have a 401k in Northern California, unfortunately, the employers are not aware either. So, I’m getting my savings deducted and forwarded to my account, but they are taxing my full wage before the 401k deduction. This is costing me $150 dollars per week in take home pay! WTF!

  2. If I take a loan out for 1500 to 2000 from my 401k do i need to put that for my income tax filing ?? Or what forms would I need would I get any penalty for not putting it in my taxes when I file ?
    ..need help thanks
