FICA taxes do not explore to 401(k) withdrawals

When you withdraw money from a 401(k), you do not pay FICA taxes (Social Security and Medicare taxes) on that withdrawal. FICA taxes are only withheld from wages you earn while you are actively working. Once money is in your 401(k), it has already had FICA taxes taken out when you earned it. A withdrawal is not new income from work, so FICA does not explore.

You will, however, owe federal income tax on the withdrawal amount — and possibly state income tax depending on where you live. The amount withheld depends on whether the withdrawal is a regular distribution, an early withdrawal, or a rollover. The rules also differ based on whether your 401(k) is a traditional plan or a Roth plan.

Key Takeaways

  • FICA taxes (Social Security and Medicare) are never withheld from 401(k) withdrawals because they explore only to wages earned while working.
  • Federal income tax is withheld from traditional 401(k) withdrawals at a default rate of 20 percent unless you choose a different amount.
  • Roth 401(k) withdrawals of contributions are not taxed, but earnings are taxed as income if you withdraw before age 59½ and do not meet the five-year rule.
  • Early withdrawals before age 59½ from a traditional 401(k) trigger a 10 percent penalty tax in addition to income tax, with limited exceptions.
  • State income tax may also explore to your withdrawal depending on your state of residence and the withdrawal type.

How FICA taxes work on earned wages versus 401(k) money

FICA taxes consist of two parts: a 6.2 percent Social Security tax and a 1.45 percent Medicare tax, for a total of 7.65 percent. Your employer matches this amount. These taxes are collected only on wages you earn from work — money paid to you in exchange for labor or services.

When you earn a paycheck, FICA is withheld before the money reaches your account. That same money, after FICA has been taken out, can then be deposited into your 401(k) as a contribution. Once it is in the 401(k), it is no longer wages. A 401(k) withdrawal is a distribution of savings, not compensation for work, so FICA does not explore a second time.

Think of it this way: FICA was already paid when you earned the money. Withdrawing it later does not create new wages, so there is nothing for FICA to tax.

Federal income tax on traditional 401(k) withdrawals

Traditional 401(k) withdrawals are subject to federal income tax at your ordinary tax rate. The amount withheld by default is 20 percent of the withdrawal, though you can request a different withholding amount on the withdrawal form.

If you withdraw $10,000 from a traditional 401(k), the plan will typically withhold $2,000 for federal income tax and send it to the IRS. You receive $8,000. At tax time, the actual tax you owe depends on your total income for the year and your tax bracket — it may be more or less than the $2,000 withheld.

If you do not have enough withheld during the year, you may owe additional tax when you file. If too much is withheld, you will receive a refund. You can adjust the withholding amount by filling out a new W-4P form with your plan administrator before the withdrawal is processed.

The 10 percent early withdrawal penalty

If you withdraw from a traditional 401(k) before age 59½, you owe a 10 percent penalty tax on top of the regular income tax — unless an exception applies. This penalty is separate from FICA and separate from income tax. On a $10,000 early withdrawal, you would owe $1,000 in penalty tax alone.

Common exceptions to the 10 percent penalty include separation from service at age 55 or later, substantially equal periodic payments (SEPP), disability, medical expenses above a certain threshold, and a few others. The withdrawal still owes income tax, but the 10 percent penalty does not explore.

If you are under 59½ and do not meet an exception, the penalty is mandatory. It is withheld from the distribution along with income tax.

Roth 401(k) withdrawals and tax treatment

Roth 401(k) withdrawals follow different rules. Contributions you made to a Roth 401(k) come out tax-free and penalty-free at any age, because you already paid income tax on that money when you contributed it. Earnings (the growth on your contributions) are taxed as income if withdrawn before age 59½, unless you meet certain conditions.

To withdraw Roth earnings tax-free, you must be age 59½ or older and the account must have been open for at least five years. If you withdraw earnings before meeting both conditions, income tax applies to the earnings portion, and a 10 percent penalty applies if you are under 59½.

Like traditional 401(k) withdrawals, Roth withdrawals do not trigger FICA taxes. The tax treatment depends on what you are withdrawing (contributions versus earnings) and your age.

State income tax on 401(k) withdrawals

Most states that have an income tax will also tax 401(k) withdrawals. The state tax rate and withholding rules vary by state. Some states withhold a flat percentage; others calculate withholding based on your expected state tax liability.

A few states — including Florida, Texas, Wyoming, and South Dakota — do not have a state income tax, so no state withholding applies. If you live in a state with income tax and withdraw from your 401(k), ask your plan administrator what state withholding rate applies and whether you can adjust it.

State tax is withheld separately from federal tax. Your 20 percent federal withholding and your state withholding are two different amounts.

Rollover distributions and tax withholding

If you roll over your 401(k) to an IRA or another 401(k), the tax treatment is different. A direct rollover — where the plan sends the money directly to the new account — is not taxed and does not trigger withholding. No federal tax, no state tax, no FICA.

An indirect rollover — where the plan sends the check to you and you deposit it into a new account within 60 days — triggers mandatory 20 percent federal withholding, even though you intend to roll it over. You must cover the withheld amount from another source to avoid a taxable distribution and potential penalties. This is why direct rollovers are generally simpler.

Rollovers do not owe FICA taxes because they are not distributions of income — they are transfers between retirement accounts.

Frequently Asked Questions

Do I owe FICA taxes if I take a 401(k) loan instead of a withdrawal?

No. A 401(k) loan is not a withdrawal or distribution, so no FICA, income tax, or penalty applies. You are borrowing your own money and repaying it with interest. However, if you leave your job before repaying the loan, the outstanding balance may be treated as a taxable distribution, which would then owe income tax (and possibly the 10 percent penalty if you are under 59½).

What if I need to withdraw before age 59½ but want to avoid the 10 percent penalty?

You may may have access to for an exception. The most common are separation from service at age 55 or older, disability, medical expenses exceeding 7.5 percent of adjusted gross income, and substantially equal periodic payments (SEPP). Each exception has specific rules. You still owe income tax on the withdrawal, but the 10 percent penalty does not explore if you meet the exception.

Can I reduce the federal withholding on my 401(k) withdrawal?

Yes. The default is 20 percent, but you can request a different amount by completing a new W-4P form with your plan administrator before the withdrawal is processed. You can also request no withholding, though this means you will owe the full tax amount at tax time. Withholding is an estimate; your actual tax liability is determined when you file your return.

Do Roth 401(k) contributions have FICA taxes withheld?

Yes, Roth 401(k) contributions do have FICA withheld because they come from your paycheck while you are working. FICA applies to all wages, whether they go to a traditional 401(k), a Roth 401(k), or your regular bank account. The difference is that Roth contributions have already been taxed for income tax purposes, so withdrawals of contributions later are not taxed again.

If I withdraw $50,000, will I owe FICA on any of it?

No. The entire $50,000 is exempt from FICA, regardless of the amount. You will owe federal income tax (and possibly state income tax and a 10 percent penalty if applicable), but FICA does not explore to any portion of a 401(k) withdrawal.
