A nonqualified withdrawal can contain taxable earnings, however, and that taxable portion is included with your other income in the Social Security calculation. For a 2025 federal return, determine whether the Roth distribution is qualified and how much is taxable before estimating your Social Security tax.
The short answer
The IRS does not treat every Roth IRA withdrawal the same way. A qualified Roth distribution is not taxable, so it ordinarily does not enter the “other income” amount used on the Social Security benefits worksheet. A nonqualified distribution may include earnings that are taxable. Those taxable earnings can raise the income used in the worksheet and may make more of your Social Security benefits taxable.

How the Social Security taxable-benefit test works
The IRS begins with a quick calculation sometimes described as provisional income:
#1 Best Overall
One-half of your Social Security benefits + other income + tax-exempt interest
“Other income” can include taxable wages, pensions, interest, ordinary dividends, capital-gain distributions and taxable portions of retirement distributions. The result is compared with a base amount determined by filing status and, for some married taxpayers filing separately, whether the spouses lived together.
| Filing situation | 2025 base amount | Important qualification |
|---|---|---|
| Single, head of household or qualifying surviving spouse | $25,000 | Federal 2025 threshold |
| Married filing jointly | $32,000 | Federal 2025 threshold |
| Married filing separately | $25,000 | Applies only if you lived apart from your spouse for all of 2025 |
| Married filing separately | $0 | Applies if you lived with your spouse at any time during 2025 |
If the calculation does not exceed the applicable base amount, the quick test indicates that none of the benefits is taxable under that test. If it exceeds the base amount, use Publication 915 Worksheet 1 or the applicable Form 1040 instructions to calculate the taxable amount. Exceeding a threshold does not mean that the entire benefit becomes taxable.
What “up to 50%” and “up to 85%” mean
Generally, as much as 50% of Social Security benefits may be included in taxable income. In higher-income circumstances, as much as 85% may be included. For 2025, the IRS identifies $34,000 for single filers and $44,000 for joint filers as income thresholds associated with the 85% maximum rule. A married-filing-separately taxpayer who lived with a spouse at any time during the year can also fall under the 85% rule.
These percentages describe the share of benefits that may be taxable, not your income-tax rate. For example, an 85% result does not mean the IRS charges an 85% tax. Your ordinary tax brackets determine the tax on the portion included in taxable income, and the worksheet determines the actual includible amount.

Where a Roth IRA withdrawal fits
Qualified Roth distribution
Publication 590-B’s Roth IRA flowchart states: “The distribution from the Roth IRA is a qualified distribution. It isn’t subject to tax or penalty.” Because a qualified distribution is not taxable, it ordinarily adds nothing to the “other income” side of the Social Security calculation.
That does not mean the withdrawal can be ignored for every recordkeeping purpose. Keep the account and distribution information that establishes its status, and confirm the result using the Roth rules for the year of the distribution. Account age, distribution ordering and your individual facts can affect the determination.

A distribution that is not qualified can contain both amounts treated as a return of contributions and an earnings portion. The taxable earnings portion is the amount that can increase other income for the Social Security worksheet. A nonqualified distribution may also be subject to the 10% additional tax, depending on the facts.
Do not enter the entire withdrawal as taxable income automatically. First determine which part is taxable under the Roth IRA rules. Conversely, do not assume that every Roth withdrawal is tax-free merely because it came from a Roth account.
| Roth distribution result | Federal income-tax treatment | Effect on Social Security calculation |
|---|---|---|
| Qualified distribution | Not subject to tax or penalty under the IRS flowchart | Ordinarily does not increase “other income” |
| Nonqualified distribution with no taxable earnings portion | No taxable amount from the distribution itself | Ordinarily no increase from the distribution |
| Nonqualified distribution with taxable earnings | Earnings portion may be taxable and may face the 10% additional tax | Taxable earnings may increase “other income” and taxable benefits |
Step-by-step process for a 2025 federal return
- Collect your benefit and income records. Use Form SSA-1099 to identify your net Social Security benefits. Gather Roth distribution records, Forms 1099-R if issued, pension and wage information, interest and dividend statements, capital-gain information, and tax-exempt interest statements.
- Classify the Roth distribution. Use the qualification flowchart and rules in the 2025 Publication 590-B. Establish whether the distribution is qualified. If it is not, separate the contribution portion from any earnings that may be taxable.
- Determine the taxable Roth amount. Only the taxable part of a nonqualified distribution belongs in taxable income. Do not use the gross amount unless the rules for your facts make the entire amount taxable.
- Compute provisional income. Take one-half of your Social Security benefits, add taxable other income—including any taxable Roth earnings—and add tax-exempt interest.
- Compare the result with your filing-status base amount. Apply the correct 2025 amount from the table above. Married taxpayers filing separately must also apply the spouse-residency rule.
- Complete the worksheet when required. If provisional income exceeds the base amount, use Publication 915 Worksheet 1 or the applicable Form 1040 instructions. The worksheet calculates the taxable benefit rather than simply declaring all benefits taxable.
- Report the result on Form 1040 or Form 1040-SR. For 2025, report net benefits from Form SSA-1099 on line 6a and the taxable portion on line 6b. Follow the instructions for any special situation that requires a different worksheet or procedure.
Examples showing the Roth difference
Single taxpayer with a qualified withdrawal
Assume a single taxpayer receives $30,000 of Social Security benefits, has $10,000 of other taxable income, receives $2,000 of tax-exempt interest, and withdraws $20,000 in a qualified Roth distribution.
Rank #3
- Half of Social Security: $15,000
- Other taxable income: $10,000
- Tax-exempt interest: $2,000
- Qualified Roth amount added: $0
- Provisional income: $27,000
The $27,000 result exceeds the 2025 single base amount of $25,000, so the taxpayer must use the worksheet. The qualified $20,000 withdrawal is not added to the calculation.

The same taxpayer with taxable Roth earnings
Now assume the Roth withdrawal is nonqualified and $8,000 of it is taxable earnings. The provisional-income calculation becomes $15,000 + $10,000 + $2,000 + $8,000 = $35,000. That is higher than the prior result and is above the $34,000 single-filer threshold associated with the 85% maximum rule. The worksheet still determines the actual taxable benefit; the threshold does not impose an 85% tax rate.
Married filing jointly
Assume a joint return reports $40,000 of Social Security benefits, $15,000 of other taxable income, and $3,000 of tax-exempt interest. With a qualified Roth withdrawal, provisional income is $20,000 + $15,000 + $3,000 = $38,000. That exceeds the 2025 joint base amount of $32,000.
If instead the couple has a nonqualified withdrawal containing $5,000 of taxable earnings, provisional income rises to $43,000. That remains below the $44,000 joint-filer threshold associated with the 85% maximum rule, but the couple still must use the worksheet because the result exceeds $32,000.
Married filing separately
The spouse-residency detail is decisive. A married-filing-separately taxpayer who lived apart from the spouse for all of 2025 uses the $25,000 base amount. A taxpayer who lived with the spouse at any time during 2025 uses a $0 base amount and can fall under the 85% rule. Use the facts that actually applied during the year rather than assuming that every separate return receives the same threshold.

Common mistakes and how to correct them
Counting a qualified withdrawal as ordinary income
Adding a qualified Roth distribution to other income overstates provisional income. Recheck the qualification determination and retain the records supporting it before completing the Social Security worksheet.
Treating the gross nonqualified withdrawal as taxable
A nonqualified distribution can contain taxable and nontaxable components. Identify the taxable earnings portion first; use that amount in the income calculation rather than automatically using the gross distribution.
Ignoring tax-exempt interest
Tax-exempt interest is included in the Social Security quick test even though it is generally excluded from regular taxable income. Omitting it can understate provisional income.
Using the wrong filing-status threshold
The $25,000, $32,000, $34,000 and $44,000 figures are not interchangeable. Apply the base amount for your filing status, then consider the separate 85% thresholds and the married-filing-separately residency rule.
Confusing the 85% maximum with an 85% tax rate
The 85% figure is the maximum share of benefits that may be included in taxable income under the applicable rules. It is not the rate applied to that income.

Using a prior-year worksheet
Social Security worksheets, thresholds and reporting instructions are year-specific. The figures in this article are for 2025 returns. Recheck the current Publication 915, Publication 590-B and Form 1040 instructions for another filing year.
Special situations and limits
Publication 915 identifies situations that can require a different worksheet or procedure, including some cases involving deductions for traditional IRA contributions and lump-sum benefits paid for earlier years. If either situation applies, do not rely on the basic quick test alone.
This explanation covers U.S. federal income tax. State treatment is not established by these federal rules and can differ by jurisdiction, so a state return requires current state-specific authority.

Quick Recap
What to remember
- A qualified Roth IRA distribution is generally tax-free and ordinarily does not increase the income used to tax Social Security benefits.
- A nonqualified distribution can include taxable earnings. Determine that taxable portion before estimating Social Security taxation.
- The IRS test uses half of Social Security benefits, other income and tax-exempt interest.
- For 2025, the principal base amounts are $25,000 for several filing statuses, $32,000 for married filing jointly, and $0 for married filing separately when the taxpayer lived with the spouse at any time.
- Up to 50% or, in applicable higher-income circumstances, up to 85% of benefits may be included in taxable income. Neither percentage is a tax rate.
- For 2025 returns, report total benefits on Form 1040 or 1040-SR line 6a and the taxable portion on line 6b.
