Taxes - Frequently Asked Questions


Do I have to pay taxes on the money I contribute to a 401(k) plan?

Your pre-tax 401(k) contributions are deducted from your pay before federal income taxes are withheld. You don't pay federal taxes on this money until you withdraw it from your 401(k) account.

However, you are required to pay Social Security tax on all 401(k) contributions.

As for state income tax, most states exempt 401(k) contributions from taxation, but depending on where you live your contributions may be subject to local income taxes.

You should check with your company's Human Resources or Benefits representative regarding the laws in your area.

What are the tax advantages of participating in a 401(k) plan?

There are three primary tax advantages to participating in a 401(k) plan. They include:

Lower Income Taxes

Because your 401(k) contribution is deducted before taxes are taken out, you're be taxed on a smaller sum of money, which makes your initial tax hit lower. An example: if you earn $30,000 per year and are in the 28% tax bracket, your federal tax liability for the year is $8,400. Under that same scenario, if you contribute 10% of your salary ($3,000) to a 401(k), your taxable income is decreased to $27,000. At a 28% tax rate, your federal income tax liability will be $7,560 – that is $840 less than you'd pay if you didn't contribute to a 401(k).

Increased Investing Power

Pre-tax investing increases your investing power by enabling you to save more. In the example above, a 10% 401(k) contribution from a $30,000 salary is $3,000 per year. Ten percent of your after-tax income, on the other hand, comes to less than $2,200. Contributing before taxes enables you to save an extra $800 per month.

Tax-Deferred Compounding

Since you don't pay taxes on your 401(k) contributions or subsequent earnings until you withdraw money at retirement, your savings accumulate faster. Say you contribute $2,000 per year to your 401(k) for 40 years, and your investment earns an annual return of 10% each year. At the end of the 40 years, you will have contributed $80,000 to your 401(k), but your account will be worth $973,684 – thanks greatly to the power of tax-deferred compounding.

Will my Social Security benefits be affected by my 401(k) plan distributions?

Not necessarily. Having a 401(k) will not reduce your Social Security benefits – but distributions from your 401(k) taken during retirement may make your Social Security benefits subject to federal income tax, especially if you have significant other income.

If you are concerned that retirement savings distributions might affect your Social Security benefits (or the taxation of those benefits) you should consult with your tax advisor, attorney, or CPA regarding your own unique situation.

Will I have to pay taxes on my 401(k) plan if I leave my company?

That depends on what you decide to do with your 401(k) money. You have several options:

A. If your vested account balance is $5,000 or more and you're under age 65, you can leave your money in your company’s 401(k) plan even when you no longer work there – and taxes won't be due until you withdraw money from the plan.

B. You can roll over your 401(k) into a rollover IRA account or into your new employer's 401(k) plan. If you do a direct rollover – have the money transferred directly into the new account – you won't owe taxes until you withdraw money from the account.

C. You can elect to take your money out of the 401(k) and not roll it over into a rollover IRA or another 401(k) plan. In this case, you will owe all applicable taxes plus the 10% early withdrawal penalty (if you are under age 59 ½) on your income tax for that year.

Can I make after-tax contributions to my 401(k) plan?

You can, but it may not be the most advisable course of action. Take a look at the following comparison between pre- and post-tax 401(k) contributions. Pre-Tax Contributions:

  • Both the contributions you make to your account and the investment gain continue to grow tax-free until you withdraw money from your account at retirement.
  • As you take money out of your 401(k), you pay taxes only on the amount you withdraw (so that at retirement, taxes don't come due on your entire account balance at once).
  • Because your 401(k) contribution is deducted from your compensation before taxes are calculated, your taxable income is lower, so you pay less income tax.
  • If you withdraw money from your 401(k) account before age 59, you will generally have to pay a penalty (except in cases of a qualified financial hardship as defined by the IRS).

Post-Tax Contributions:

  • Because post-tax contributions are made with money you've already paid taxes on, only the investment's gain or income (i.e. interest and dividends) - and not your contributions - enjoy the benefit of tax-deferred growth.
  • When you withdraw post-tax 401(k) funds you only pay taxes on the gain (interest or dividends) your investment has earned. As with pre-tax contributions, taxes are due only when you take money out of your account.
  • Post-tax contributions are not tax-deductible, so you don't get a tax break for making them.
  • Depending on your plan's rules, you may be able to withdraw your post-tax contributions at any time without incurring a penalty. However, because the gain you earn on your post-tax 401(k) investment is tax-deferred, you must pay income tax on that amount when you withdraw your money. The gain is also subject to an early withdrawal penalty if withdrawn before age 59 _ (except in cases of a qualified financial hardship as defined by the IRS).

Now, considering that the best tax break and the greatest opportunity for taking advantage of tax-deferred compounding come with pre-tax 401(k) contributions, why would anyone consider making post-tax contributions? Here are some possible scenarios:

  • If you are already making the maximum pre-tax 401(k) contribution allowed and really want to contribute more (to get the benefit of tax-deferred investment growth).
  • If your employer matches both pre-tax and post-tax contributions, and you are fully vested for matching contributions, you might choose to maximize the employer match by making the maximum allowable pre-tax contribution and making post-tax contributions as well.
  • If you are committed to saving money, but aren't sure you'll be able to leave your money invested until retirement, you might make after-tax contributions because you will be able to withdraw them without penalty before age 59 1/2. A person considering this idea needs to remember that the gain earned on the investment is subject to an early withdrawal penalty if taken out before age 59 1/2. Also, income tax on the investment gain is due at the time of withdrawal.

The 401(k) is an investment vehicle for retirement. If retirement is not the goal, there is probably a more appropriate vehicle for post-tax investment dollars.
