Are 401(k) Withdrawals Earned Income? Tax Rules Explained

Here's a mistake that costs retirees real money: assuming that because 401(k) withdrawals are taxable, they're "earned income." They're not. And the distinction between taxable income and earned income matters for at least four different parts of your financial life.

Your 401(k) withdrawal shows up on your tax return. The IRS taxes it at your ordinary rate. But the Social Security Administration, the IRA contribution rules, the Earned Income Tax Credit, and your Medicare premiums all treat it differently than a paycheck. Getting this wrong can mean overpaying in one area or missing a benefit in another.

The short version: 401(k) withdrawals are ordinary income, taxed at your marginal rate. But they are not earned income. They don't count toward the Social Security earnings test, they don't qualify you for IRA contributions, and they don't trigger FICA taxes. They do increase your AGI, which affects Medicare premiums and Social Security taxation.

The Distinction That Matters

The IRS defines earned income as compensation for personal services: wages, salaries, tips, commissions, and net self-employment income [1]. That's it. Money you actively work for today.

401(k) withdrawals don't qualify. Neither do pension payments, annuity income, interest, dividends, or rental income. These are all "ordinary income" for tax purposes, but not "earned income" for benefits purposes.

Why does the IRS make this distinction? Because several tax provisions are designed specifically to reward or assist people who work. The earned income definition draws a line between active labor and passive receipt of money.

That middle column is where most of the confusion lives.

Impact #1: Social Security Earnings Test

If you're collecting Social Security benefits before reaching full retirement age (67 for most people today) and still working, the earnings test can temporarily reduce your benefits. In 2026, the annual limit is expected to be around $24,000 to $25,000. Earn more than that from a job, and Social Security withholds $1 for every $2 over the limit [2].

Here's the key: 401(k) withdrawals don't count.

Worked Example: Marcus, Age 64

Marcus is collecting Social Security ($2,000/month) while working part-time as a consultant earning $29,000 a year. He also withdraws $20,000 from his Traditional 401(k).

Earnings test calculation:

• Only the $29,000 in wages counts
• The $20,000 from the 401(k) is ignored entirely
• Excess over limit (using $24,000 estimate): $29,000 − $24,000 = $5,000
• Benefit reduction: $5,000 ÷ 2 = $2,500 withheld for the year

If Marcus assumed his 401(k) withdrawal counted, he might think he's $25,000 over the limit and facing a $12,500 reduction. He'd be wrong by $10,000. The 401(k) triggered exactly zero dollars in benefit reduction.

One important note: the withheld amount isn't lost forever. Once Marcus reaches full retirement age, Social Security recalculates his benefit to account for the months payments were withheld. But understanding the earnings test correctly avoids unnecessary panic (and bad decisions like not taking needed 401(k) withdrawals).

Impact #2: IRA Contributions

To contribute to any IRA (Traditional or Roth), you need earned income at least equal to your contribution amount. In 2026, the contribution limit is $7,000 ($8,000 if you're 50 or older) [3].

401(k) withdrawals don't count as earned income for this purpose. If your only income in retirement comes from 401(k) distributions and Social Security, you cannot make a new IRA contribution. Period.

This catches people off guard. A retiree pulling $60,000 from a 401(k) might assume they can contribute $8,000 to a Roth IRA. They can't, unless they have at least $8,000 in wages or self-employment income that year [1].

There's a workaround, though. You can do a Roth conversion (moving money from a Traditional IRA to a Roth IRA), which has no earned income requirement. A conversion isn't a contribution. It's a transfer. Different rules apply. The money is still taxable in the year of conversion, but it doesn't require that you worked.

Impact #3: The Earned Income Tax Credit

The EITC is one of the most valuable tax credits available to low-income workers. For 2026, it can be worth over $7,000 for families with three or more qualifying children [4].

401(k) withdrawals don't qualify you for the EITC because they're not earned income. But here's the twist: they can disqualify you. The EITC has an investment income limit (around $11,600 in 2025, adjusted annually) [4]. While 401(k) withdrawals aren't technically "investment income" for most purposes, the interaction between the withdrawal, your AGI, and the credit calculation can effectively price you out.

This matters most for semi-retired workers with low wages who supplement with retirement account distributions. The credit is designed for working people, and the IRS enforces that strictly.

Impact #4: No FICA Taxes

When you earned your salary, you paid 7.65% in FICA taxes (6.2% Social Security + 1.45% Medicare), and your employer matched it. On the $20,000 Marcus withdrew from his 401(k), he pays $0 in FICA.

This is actually good news. On a $20,000 withdrawal, that's a savings of $1,530 compared to earning the same amount from a job. You still owe ordinary income tax, but not payroll tax.

The 2026 Social Security wage base is projected at approximately $184,500 [5]. You pay Social Security tax on earned income up to that amount. Your 401(k) withdrawal? Zero Social Security tax, regardless of the amount.

(There's something almost absurd about it: you spent your career paying FICA on every paycheck, and now the same dollars come back to you FICA-free. The government already got its payroll cut decades ago.)

Impact #5: Medicare Premiums

Here's where 401(k) withdrawals can hurt. Medicare Part B and Part D premiums are based on your Modified Adjusted Gross Income (MAGI) from two years prior. 401(k) withdrawals increase your MAGI.

In 2026, if your MAGI exceeds $206,000 (married filing jointly) or $103,000 (single), you'll pay higher premiums through the Income-Related Monthly Adjustment Amount, known as IRMAA.

A large 401(k) withdrawal in 2024 could mean higher Medicare premiums in 2026. A Roth conversion has the same AGI impact (it's still income), but at least the converted money won't cause future AGI increases when you withdraw it from the Roth.

The Full Tax Picture: Marcus in 2026

Let's complete Marcus's tax return to see how everything fits together.

Income:

• Part-time consulting wages: $29,000
• 401(k) withdrawal: $20,000
• Total gross income: $49,000

Standard deduction (single filer, 2026): $16,100

Taxable income: $49,000 − $16,100 = $32,900

Federal income tax:

• 10% on first $12,400 = $1,240
• 12% on remaining $20,500 = $2,460
• Total tax: $3,700

FICA tax on wages only: $29,000 × 7.65% = $2,219 FICA on 401(k): $0

Marcus's total federal tax burden: approximately $5,919 on $49,000 of income (effective rate: 12.1%). If the entire $49,000 had been wages, his FICA alone would have been $3,749, bringing the total closer to $7,449. The 401(k) withdrawal saved him roughly $1,530 in payroll taxes.

Your Next Move

1. Know the distinction. Earned income = work. 401(k) income = past savings. They're taxed differently, and benefits rules treat them differently. Don't conflate them.

2. If you're collecting Social Security early, don't panic about 401(k) withdrawals. They won't trigger the earnings test. Take what you need.

3. If you want to contribute to a Roth IRA in retirement, you need earned income. Even $8,000 from freelance work or a part-time job unlocks the door. Without it, consider a Roth conversion instead.

4. Watch your AGI for Medicare purposes. Large 401(k) withdrawals or Roth conversions in any given year will affect premiums two years later. Spread large distributions over multiple years when possible. Use our compound interest calculator to model the impact.

5. Check your state rules. Some states exempt retirement income from state taxes entirely. Others tax it just like wages. This varies enormously and can shift the calculus on which account to draw from.
