Qualified Roth IRA withdrawals generally create less taxable Social Security income than taxable traditional IRA withdrawals of the same amount. A qualified Roth distribution is excluded from gross income, so it is left out of the IRS combined-income calculation. A taxable traditional IRA distribution is ordinary income and can push more of your Social Security benefit into the taxable portion of your federal return.
This comparison concerns federal taxation of benefits, not the size of your Social Security check or the earnings test that can withhold benefits from people who work before full retirement age. The result can change if a Roth withdrawal is nonqualified, a traditional IRA distribution is partly tax-free because of basis, or a traditional IRA payment is an excludable qualified charitable distribution (QCD).

Which IRA withdrawal creates less taxable Social Security income?
A qualified Roth IRA withdrawal does. The IRS does not add it to the “other income” used in its Social Security worksheet. A fully taxable traditional IRA distribution is added dollar for dollar, which can make part of your benefit taxable even when the benefit was previously entirely tax-free.
This is a marginal comparison, not a lifetime verdict that Roth is always better. Roth contributions are not deductible, while eligible traditional IRA contributions may be deductible. The narrow question is what happens when money comes out while Social Security is on your return.

How does the IRS decide whether Social Security is taxable?
IRS Publication 915 starts with a base-amount test. Compare your filing-status base amount with half of your Social Security benefits plus all other income, including tax-exempt interest. Planners often call that total “combined income” or “provisional income.”
For the quick calculation, Worksheet A uses:
- Line A: Box 5 of Form SSA-1099 or RRB-1099, your net benefits.
- Line B: One-half of line A.
- Line C: Taxable income other than Social Security, including pensions, wages, interest, ordinary dividends and capital-gain distributions. Do not subtract deductions or exclusions here.
- Line D: Tax-exempt interest, such as municipal-bond interest.
- Line E: Lines B + C + D.
If line E is at or below your base amount, none of your benefits are taxable federally. If it is above the base, complete Worksheet 1 to calculate the included amount.

The percentages are inclusion limits, not tax rates. In the middle band, no more than 50% of benefits is included. Above the second threshold, as much as 85% can be included, but at least 15% of the benefit remains outside federal taxable income under these domestic rules. The included amount is then taxed at your ordinary income-tax rates.
Do not begin with Form 1040 adjusted gross income after taxable Social Security has already been entered on line 6b. Worksheet A is designed to use other income first and add half of the benefits once; adding the taxable benefit again would double count it.
What does the Roth-versus-traditional difference look like in numbers?
Consider a single filer receiving $20,000 of Social Security and having no other income. Half the benefit is $10,000, so combined income is $10,000—below the $25,000 base amount. None of the benefit is taxable.
If the person instead takes a fully taxable $20,000 traditional IRA distribution, combined income rises to $30,000. That is $5,000 over the base and still below $34,000. In this band, taxable benefits are the smaller of half the benefit ($10,000) or half the excess over the base ($2,500). The return therefore includes $2,500 of Social Security plus the $20,000 traditional IRA distribution as ordinary income.
If the same $20,000 is a qualified Roth distribution, it is not entered as other income. Combined income remains $10,000, and taxable Social Security remains $0. The example shows the mechanical effect; your result depends on benefit amount, filing status, wages, pensions, interest, capital gains, tax-exempt interest and other income.
Why do qualified Roth withdrawals stay out of the Social Security test?
Publication 590-B says qualified Roth distributions and distributions that return regular contributions are not included in gross income. Because they are not gross income, they are not line C income on Worksheet A and do not raise combined income.

A Roth distribution is qualified only when both conditions are met:
- The five-year period beginning with the first tax year for which a contribution was made to a Roth IRA for your benefit has been satisfied.
- The payment is made after age 59½, because of disability, to a beneficiary or estate after death, or under the first-home exception (up to a $10,000 lifetime limit).
Age 59½ alone is not enough if the five-year requirement has not been met. Conversely, satisfying the five-year period does not make every early distribution tax-free.

Regular contributions come out first, then conversion and rollover amounts, then earnings. Returned regular contributions were already taxed and generally do not enter gross income. Taxable earnings taken before the distribution is qualified can enter income and therefore can increase the Social Security test. A conversion has its own five-year clock for the 10% additional tax on taxable converted amounts; that clock is not necessarily the same as the five-year period for a qualified Roth distribution.
Why do traditional IRA distributions increase combined income?
Traditional IRA distributions are generally taxable in the year received, and the taxable portion is ordinary income. A fully taxable distribution therefore goes on Worksheet A as other income, alongside wages, pensions and interest.
If all of your traditional IRA contributions were deductible, you generally have no basis and the entire distribution is taxable. If you made nondeductible contributions or rolled after-tax money into the IRA, part of each distribution can be tax-free. Publication 590-B treats basis under a pro-rata rule: until all basis has been distributed, every payment is partly nontaxable and partly taxable. You cannot designate a withdrawal as “basis only” while leaving all taxable money behind.
Only the taxable slice raises combined income. Keep Form 8606 and prior-year records so the basis percentage is calculated correctly; an incorrect assumption that a payment is entirely tax-free can understate both income tax and taxable Social Security.
Can a traditional IRA payment avoid increasing taxable Social Security?
Yes. The main traditional-IRA exception is an excludable qualified charitable distribution. A QCD is paid directly by the IRA trustee to an eligible charity, and the owner must be at least age 70½. An excludable QCD is not included in gross income, so it does not go on Worksheet A line C.
Publication 590-B’s 2025 narrative gives an annual QCD exclusion of $108,000 per person; a spouse filing jointly can have a separate $108,000 limit. The publication’s illustrated 2026 worksheet prints a line cap of $111,000. Treat those as the figures shown in the respective publication material, not as interchangeable limits. A one-time QCD to a split-interest entity is limited to $54,000 in the same publication.

A QCD must be made directly to an eligible organization, and you cannot also claim the excluded amount as a charitable deduction. It counts toward your required minimum distribution. Any amount over the excludable limit is treated like another taxable IRA distribution and can increase combined income. Deductible IRA contributions made after age 70½ can also reduce the amount eligible for exclusion.
How does a Roth conversion affect Social Security taxation?
A Roth conversion is taxable in the conversion year, even though it is a rollover for Roth-account purposes. Publication 590-B states that a conversion distribution is included in gross income under the traditional-IRA rules. If you are already receiving Social Security, the converted amount can push combined income above the $25,000/$32,000 base or the $34,000/$44,000 second threshold, making more of that year’s benefit taxable.

Why do required minimum distributions make the difference recur?
Under the age rule printed in Publication 590-B (2025), an owner of a traditional IRA must begin required minimum distributions by April 1 of the year after reaching age 73. Those distributions are generally taxable and can keep adding to combined income while Social Security is being received.
An original Roth IRA owner has no lifetime required minimum distributions regardless of age. Beneficiaries of Roth IRAs can have distribution obligations. Some later-law summaries say the traditional-IRA starting age reaches 75 for people born in 1960 or later; that is not the age sentence printed in the 2025 publication, so verify the rule for your birth year and tax year before planning.

Does an IRA distribution affect the Social Security earnings test?
No. IRA distributions are not wages or net earnings from self-employment, so they do not by themselves trigger withholding under the earnings test for someone claiming before full retirement age. They can, however, make more of your benefit taxable on your federal return if the distribution is included in combined income.
The earnings test and benefit-taxation test answer different questions. A 2026 summary from The Motley Fool reports a $24,480 earnings limit for someone whose full retirement age is after 2026, with $1 withheld for every $2 above the limit, and a $65,160 limit for someone reaching full retirement age in 2026, with $1 withheld for every $3 above it. Those figures are attributed to that published summary, not to an SSA page retrieved here. The durable point is that the test measures work earnings, while taxable-benefit rules measure combined income.

Does the enhanced senior deduction eliminate Social Security taxation?
No. The senior deduction can reduce taxable income after the Social Security worksheet has determined how much benefit is included; it does not change the Publication 915 base amounts.
Publication 17 says taxpayers born before January 2, 1961, may qualify for an enhanced senior deduction, subject to modified-adjusted-gross-income limits of $75,000 for single filers and $150,000 for joint filers. The maximum is $6,000, or $12,000 if both spouses are eligible, and it is claimed on Schedule 1-A. A large traditional IRA withdrawal or Roth conversion can both increase modified AGI and make more Social Security taxable, while also phasing down or eliminating this deduction.
One 2026 calculator note reports that proposals described as “no tax on Social Security” did not repeal the federal benefit-taxation rules. Use the IRS worksheet first, then apply available deductions.
What changes for married filing separately?
Married filing separately is unusually important. If spouses lived apart for the entire year, the 2025 base amount is $25,000. If they lived together at any time, the base amount is $0, so the special rules can make up to 85% of benefits taxable with very little other income.
Do not apply the single-filer thresholds automatically to a married-separate return. Establish whether the spouses lived together at any point during the year before estimating the effect of an IRA withdrawal.

- Calculate baseline combined income. Use half of your net Social Security, all other taxable income and tax-exempt interest.
- Identify the threshold band. Compare the total with your $25,000/$32,000 base and $34,000/$44,000 second threshold, or the married-separate rules.
- Classify the withdrawal. Confirm whether the Roth payment is qualified, whether a traditional payment includes basis, or whether a QCD can meet the need.
- Fill the lower bands first. If a traditional withdrawal would cross a threshold, consider whether a qualified Roth withdrawal or an excludable QCD can supply the same spending amount.
- Check one-year side effects. Include ordinary tax brackets, the senior deduction’s modified-AGI phaseout and any other income-tested items relevant to you. Medicare IRMAA effects can also depend on modified AGI, but specific brackets and premiums require current CMS data.
- Recalculate after the withdrawal. Use Worksheet A and, when required, Worksheet 1 rather than relying on an AGI shortcut.
Roth spending is most valuable for tax control when the withdrawal is qualified and your traditional IRA, pension or other income is close to a Social Security threshold. Traditional withdrawals may still be sensible when the money is deductible, when your current marginal tax rate is low, or when preserving Roth assets for later years or heirs is more important.

- Calling 85% a tax rate. It is the maximum share of benefits included in income; ordinary tax rates apply to that included amount.
- Adding Social Security twice. Do not start with AGI that already includes line 6b and then add half the benefit again.
- Assuming every Roth withdrawal is tax-free. Check the five-year rule, age or exception, and the ordering of contributions, conversions and earnings.
- Ignoring tax-exempt interest. Municipal-bond interest is included in the combined-income calculation even though it is generally exempt from regular federal income tax.
- Choosing “basis only” from a traditional IRA. The pro-rata rule generally makes each distribution partly taxable and partly nontaxable when basis exists.
- Counting a QCD as a charitable deduction. The excluded QCD is not also deductible, and the payment must go directly from the trustee to an eligible charity.
- Confusing taxable benefits with a reduced check. A traditional IRA distribution can increase tax without changing the Social Security payment or earnings-test eligibility.
- Using outdated thresholds. Publication 915 (2025) still prints $25,000, $32,000, $34,000 and $44,000; verify the publication for the tax year you are filing.
What about nonresident aliens and state taxes?
The domestic Worksheet A and Worksheet 1 rules do not apply to a nonresident alien. Publication 915 generally taxes 85% of benefits at a 30% rate unless a treaty exempts or lowers the rate. The publication lists treaty provisions for several countries, including Canada, Egypt, Germany, Ireland, Israel, Italy, Japan, Romania and the United Kingdom, with narrower provisions for India and a 15% rate for residents of Switzerland.

Which account is the answer to the title question?
For federal Social Security taxation, qualified Roth IRA withdrawals create less taxable Social Security income than equally sized taxable traditional IRA withdrawals. The Roth amount stays out of combined income; the taxable traditional amount enters it and can move benefits into the 50% or 85% inclusion bands.
That conclusion has important boundaries. Nonqualified Roth earnings can be taxable, traditional IRA basis can make only part of a payment taxable, a direct QCD can be excluded, and a Roth conversion is taxable in the year of conversion. Compare those facts with your filing status, projected benefits, other income, required distributions and deductions before deciding which account to draw first.
Frequently Asked Questions
Do Roth IRA withdrawals count as earned income for Social Security?
No. IRA distributions are not wages or self-employment earnings, so they do not count under the pre-full-retirement-age earnings test. A nonqualified Roth distribution can still be taxable income for the separate benefit-taxation calculation.
Can I make a traditional IRA withdrawal entirely from my nondeductible contributions?
Usually not. The IRS pro-rata rule generally treats each distribution as containing a taxable and a nontaxable share until all basis has been recovered. Form 8606 records the basis used in that calculation.
Does a qualified charitable distribution reduce my required minimum distribution?
Yes, when it is made directly by the IRA trustee to an eligible charity and otherwise meets QCD rules. The excluded amount counts toward the RMD, but it is not also claimed as a charitable deduction.
Will a Roth conversion make this year’s Social Security taxable?
It can. The taxable converted amount is included in gross income in the conversion year, so it can raise combined income above a Social Security threshold even though later qualified withdrawals from the Roth can be excluded.
