Do You Pay Social Security Tax on IRA Withdrawals?

You do not pay Social Security tax on IRA withdrawals. The 6.2% Social Security tax and the 1.45% Medicare tax that make up FICA apply only to wages and self-employment earnings, and a distribution from a traditional, Roth, SEP, or SIMPLE IRA is neither. Your custodian will never withhold those payroll taxes from a distribution, regardless of your age or the amount. The catch is indirect: a traditional IRA withdrawal is ordinary income for federal tax purposes, and that added income can make part of your Social Security benefits taxable and push your Medicare premiums higher two years down the road.

Why Payroll Taxes Don’t Apply

FICA (for employees) and SECA (for the self-employed) are calculated on remuneration for work or on net earnings from a business you actively run.¹ Federal law defines “wages” for FICA purposes as remuneration paid for employment.² An IRA distribution is investment income coming out of a retirement account, not pay for services. It falls outside the definition entirely.

The dollars in a traditional IRA were also already subject to payroll tax back when you earned them and contributed them. Charging FICA again at withdrawal would tax the same wages twice. The exemption applies to every type of IRA and to every distribution, whether qualified, early, or a required minimum distribution.

What You Do Owe on a Traditional IRA Withdrawal

Traditional IRA distributions are taxable as ordinary income in the year you receive them.³ Any deductible contributions and all investment earnings are fully taxable at your regular federal rate; if you made nondeductible contributions with money you already paid tax on, that portion comes back tax-free.⁴

Your rate depends on total taxable income for the year, with the withdrawal stacked on top of pensions, part-time wages, or other income. For 2026, federal brackets range from 10% to 37%.⁵ A large one-time withdrawal can push the marginal dollars into a higher bracket, which is why many retirees spread distributions across several years.

Roth IRAs Work Differently

Roth contributions go in after tax, so qualified distributions come out entirely tax-free, including the growth.⁶ A distribution is qualified when the account has been open for at least five tax years and you are at least 59½, disabled, or using up to $10,000 for a first-time home purchase.⁴ Qualified Roth withdrawals also stay out of the Social Security taxation formula and the Medicare premium calculation below, which makes them one of the few retirement income sources that doesn’t ripple into other costs.

How an IRA Withdrawal Can Tax Your Social Security Benefits

This is where a traditional IRA distribution causes damage people don’t see coming. Under 26 U.S.C. §86, the IRS decides how much of your Social Security is taxable using a figure called combined income: your adjusted gross income, plus any tax-exempt interest, plus half of your Social Security benefits.⁷ A traditional IRA withdrawal flows straight into adjusted gross income, so it can push you across the thresholds where benefits become taxable:

Single filers with combined income between $25,000 and $34,000: up to 50% of Social Security benefits become taxable.
Single filers above $34,000: up to 85% of benefits become taxable.
Joint filers between $32,000 and $44,000: up to 50% of benefits become taxable.
Joint filers above $44,000: up to 85% of benefits become taxable.

These thresholds have never been indexed for inflation since they were set in 1983 and 1993, so more retirees cross them every year.⁷ Consider a retiree with $18,000 in Social Security and $20,000 in other income who owes no tax on the benefits. Add a $15,000 IRA withdrawal and part of the benefits become taxable too. The IRA distribution itself is taxed, and it drags previously sheltered income into tax at the same time.

How an IRA Withdrawal Can Raise Your Medicare Premiums

A traditional IRA distribution can also increase your Medicare Part B and Part D premiums through a surcharge called IRMAA, the Income-Related Monthly Adjustment Amount. Medicare uses your modified adjusted gross income from two years earlier to set the current year’s premium, so a 2024 return determines 2026 IRMAA.⁸

For 2026, single filers with income above $109,000 and joint filers above $218,000 start paying IRMAA on top of the standard Part B premium. The surcharges climb through several tiers:

Single $109,001–$137,000 (joint $218,001–$274,000): $81.20 per month.
Single $137,001–$171,000 (joint $274,001–$342,000): $202.90 per month.
Single $171,001–$205,000 (joint $342,001–$410,000): $324.60 per month.
Single $205,001–$499,999 (joint $410,001–$749,999): $446.30 per month.
Single $500,000 or more (joint $750,000 or more): $487.00 per month.

At the top tier, the Part B surcharge alone runs $5,844 per year. A single large withdrawal can trigger surcharges two years later, long after the money has been spent.⁸ If a life-changing event like retirement, divorce, or the death of a spouse dropped your income after the reference year, you can file Form SSA-44 to ask Social Security to use a more recent year instead.⁹

Ways to Keep the Indirect Costs Down

Spreading distributions across multiple years is the simplest lever. A steady, smaller withdrawal often keeps combined income under the 50% and 85% Social Security thresholds and under the IRMAA tiers, while a lump sum blows through both.

Drawing from a Roth in a high-income year is another. Qualified Roth distributions don’t count in adjusted gross income, so they can fund a big expense without lifting the taxation of benefits or triggering IRMAA.

If you’re 70½ or older and give to charity, a qualified charitable distribution moves up to $111,000 per year in 2026 directly from your traditional IRA to an eligible charity.¹⁰ The transfer never hits your adjusted gross income, which keeps combined income lower for the Social Security formula and for IRMAA. A QCD also counts toward your required minimum distribution for the year.¹¹

Two Other Taxes to Keep Separate

People sometimes confuse the Social Security question with two other charges on IRA money. Neither is a payroll tax.

The first is the 10% early withdrawal penalty. If you take money out before age 59½, you owe an extra 10% on the taxable portion of the distribution.¹² Exceptions cover disability, up to $10,000 for a first-time home purchase, unreimbursed medical expenses above 7.5% of adjusted gross income, higher education costs, health insurance premiums during unemployment, up to $5,000 per birth or adoption, and one emergency distribution per year up to $1,000.¹³
