Qualified Roth IRA distributions do not count toward your AGI. Federal law excludes them from gross income entirely, so they never enter the adjusted gross income calculation on your return.1GovInfo. 26 USC 408A – Roth IRAs Non-qualified distributions are treated differently: any earnings you pull out are taxable and do increase your AGI, though contributions and already-taxed conversion amounts still come out clean.
What Makes a Distribution Qualified
A Roth IRA withdrawal is “qualified,” and therefore invisible to your AGI, only when it passes two tests at the same time.
The first is the five-year holding period. The clock starts on January 1 of the tax year you made your first contribution to any Roth IRA, and a single clock covers every Roth IRA you ever open. If your first contribution was made in April 2022 for the 2021 tax year, the five-year period ran from January 1, 2021 through December 31, 2025.2Cornell Law Institute. 26 USC 408A(d)(2) – Qualified Distribution
The second test requires one of four triggering events:
- You are at least age 59½.
- The distribution goes to a beneficiary or your estate after your death.
- You are totally and permanently disabled under the IRS definition.3Internal Revenue Service. Retirement Topics – Disability
- You use up to $10,000 (lifetime cap) for a first-time home purchase.4Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
Miss either test and the distribution is non-qualified. That doesn’t automatically mean tax is owed, but it does mean the IRS looks at what you’re withdrawing to decide whether anything gets added to your income.
How a Qualified Distribution Shows Up on Your Return
When a distribution qualifies, the gross amount is reported on Form 1040 line 4a, and line 4b (the taxable amount) is zero. If the entire distribution is qualified, you don’t need to complete Part III of Form 8606; the instructions state that “if you don’t have an amount to enter on line 19, don’t complete Part III; your Roth IRA distribution(s) isn’t taxable.”5Internal Revenue Service. Instructions for Form 8606 (2025) Your custodian will issue a 1099-R with distribution code Q in Box 7, telling the IRS the payer verified both the five-year rule and a triggering event.6Internal Revenue Service. Instructions for Forms 1099-R and 5498 Because none of it is includible in gross income, none of it flows into AGI.
When a Non-Qualified Distribution Adds to AGI
The IRS treats every dollar leaving a Roth IRA as coming out of three buckets in a fixed order, and you empty each bucket before moving to the next:7Internal Revenue Service. Publication 590-B (2025), Distributions from Individual Retirement Arrangements
- Regular contributions come out first. You already paid income tax on this money, so it is always tax-free and never touches AGI, no matter your age or how long the account has existed.
- Conversion and rollover amounts come out second, on a first-in, first-out basis. The taxable portion of each conversion (the pre-tax money you included in income when you converted) comes out before its nontaxable portion. These amounts are generally income-tax-free on the way out because the tax was paid at conversion, but the 10% early withdrawal penalty can apply if you withdraw the taxable portion within five years of that specific conversion and you’re under 59½.8Internal Revenue Service. Topic No. 557, Additional Tax on Early Distributions from Traditional and Roth IRAs
- Earnings come out last. Earnings pulled out in a non-qualified distribution are the only bucket that gets included in gross income, and that amount flows straight into AGI.
The ordering matters in practice. If you contributed $80,000 over the years and the account is now worth $110,000, a $50,000 non-qualified withdrawal reaches only contributions, adds nothing to your AGI, and owes no penalty. Earnings enter the picture only after every dollar of contributions and conversion principal is gone.
Once earnings do come out in a non-qualified distribution, they are taxed at ordinary income rates and typically hit with a 10% early withdrawal penalty unless an exception applies, such as reaching 59½, disability, or the $10,000 first-time homebuyer allowance.4Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions To figure the taxable portion, complete Part III of Form 8606 and track your basis, meaning the running total of all contributions and conversion amounts.5Internal Revenue Service. Instructions for Form 8606 (2025) Without those records, you risk paying tax on money that should have come out free.
Why Keeping Roth Distributions Out of AGI Is Worth Something
AGI is the trigger for a long list of thresholds. When qualified Roth withdrawals stay out of it, they don’t set off any of these consequences. When earnings from a non-qualified distribution land in AGI, they can.
Medicare Premium Surcharges
Medicare Part B and Part D premiums carry Income-Related Monthly Adjustment Amounts (IRMAA) tied to your modified AGI from two years earlier. For 2026, single filers with MAGI at or below $109,000 pay the standard Part B premium of $202.90 per month. Above that threshold, the surcharge starts at $81.20 per month and rises to $487.00 per month at incomes of $500,000 or more.9CMS. 2026 Medicare Parts A and B Premiums and Deductibles The first joint-filer threshold is $218,000. Medicare’s MAGI is your AGI plus tax-exempt interest.10SSA. POMS HI 01101.010 – Modified Adjusted Gross Income (MAGI) Taxable Roth earnings that reach your AGI in one year can bump you into a higher IRMAA tier two years later.
Taxation of Social Security Benefits
Whether your Social Security benefits get taxed depends on “combined income,” which is your AGI plus nontaxable interest plus half your benefits. Qualified Roth withdrawals don’t appear in AGI, so they don’t push more of your benefits into taxable territory. That’s a meaningful edge if you’re supplementing Social Security in retirement.
Net Investment Income Tax
The 3.8% Net Investment Income Tax kicks in when modified AGI exceeds $200,000 for single filers or $250,000 for joint filers.11Internal Revenue Service. Net Investment Income Tax Taxable Roth earnings that inflate AGI can drag your investment income into this tax.
Deductions and Credits
Medical expenses are only deductible above 7.5% of AGI, so a higher AGI shrinks the deduction.12Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses Credits like the Earned Income Tax Credit and the American Opportunity Tax Credit phase out at AGI thresholds. And your ability to make new Roth IRA contributions is itself tied to MAGI, which builds on AGI.13Internal Revenue Service. Modified Adjusted Gross Income Taxable earnings from a non-qualified distribution can, in the same year, both add to your tax bill and knock you out of eligibility for other benefits.
A Few Boundaries Worth Knowing
Roth conversions are a separate matter from Roth distributions. When you convert pre-tax money from a traditional IRA or 401(k) into a Roth, the converted amount is included in your gross income for that year and adds to AGI, even though you haven’t spent any of it. A $50,000 conversion adds $50,000 to that year’s AGI. The conversion itself doesn’t trigger the 10% early withdrawal penalty, but withdrawing those converted funds from the Roth within five years and before age 59½ can, under the ordering rules above.7Internal Revenue Service. Publication 590-B (2025), Distributions from Individual Retirement Arrangements
For an inherited Roth IRA, the five-year clock that matters is the original owner’s, not yours. If that clock was already satisfied at the owner’s death, earnings you later withdraw are tax-free and stay out of your AGI. If the account was less than five years old when the owner died, earnings withdrawn before the five-year mark can be taxable and would count toward your AGI.14Internal Revenue Service. Retirement Topics – Beneficiary Contributions from an inherited Roth always come out tax-free.
If you take a Roth distribution and realize it was a mistake, you generally have 60 days to roll the full amount back into a Roth IRA, in which case it’s not included in gross income and doesn’t reach AGI.15Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions You’re limited to one indirect rollover per 12-month period across all your IRAs, and if any tax was withheld from the distribution, you’ll need to replace the withheld amount from your own funds to roll the full amount over. Otherwise, the shortfall is treated as a taxable distribution and lands in your AGI.
