RMDs and the Senior Deduction: Using One to Offset the Other in 2026
Required minimum distributions add to your taxable income every year after age 73, and there is no way to avoid them from traditional retirement accounts. However, the OBBBA's $6,000 senior bonus deduction can partially offset this tax hit by reducing your adjusted gross income. For a 75-year-old with a $400,000 IRA, the RMD is $16,260 and the senior deduction trims $6,000 from AGI, saving roughly $720 in federal tax at the 12% bracket. Here is how the two interact.
How RMDs increase taxable income
Distributions from traditional IRAs and 401(k) plans are taxed as ordinary income. When you take an RMD, the full amount is added to your gross income on Form 1040 (unless you made nondeductible contributions, in which case a pro-rata portion may be excluded).
For many retirees, the RMD is one of the largest components of their taxable income. A $400,000 IRA at age 75 (distribution period 24.6) produces an RMD of $16,260. At age 80, the same balance would require $19,802. At age 85, it rises to $25,000.
This income can push retirees into higher tax brackets, increase the taxable portion of Social Security benefits, and trigger Medicare IRMAA surcharges. The compounding effect is that each dollar of RMD income can cost more than the marginal tax rate alone.
The senior deduction as an offset
The OBBBA senior bonus deduction reduces AGI by up to $6,000 per qualifying taxpayer age 65 or older. Because it is above the line, it directly offsets income from any source, including RMDs.
Think of it as a $6,000 buffer against the tax impact of your RMD. The RMD adds to income; the senior deduction subtracts from income. The net effect on AGI is the RMD minus the senior deduction (assuming no phase-out):
Net AGI impact of RMD after senior deduction
RMD income: $16,260
Senior bonus deduction: -$6,000
Net addition to AGI from RMD: $10,260
The deduction does not eliminate the RMD requirement. You must still withdraw the full $16,260. But the deduction means $6,000 of that withdrawal is effectively sheltered from income tax.
Worked example: age 75 with $400,000 IRA
Consider Patricia, a 75-year-old single filer with the following income in 2026:
- Traditional IRA balance (Dec 31, 2025): $400,000
- Social Security benefits: $22,000
- Small pension: $10,000
RMD calculation
IRA balance: $400,000
Distribution period (age 75): 24.6
RMD: $400,000 / 24.6 = $16,260
Without senior deduction
Gross income (RMD + pension): $16,260 + $10,000 = $26,260
AGI: $26,260
Standard deduction (65+ single): $16,100 + $2,050 = $18,150
Taxable income: $8,110
With senior deduction
Gross income: $26,260
Senior bonus deduction: -$6,000
AGI: $20,260
Standard deduction (65+ single): $18,150
Taxable income: $2,110
The senior deduction reduces Patricia's taxable income by $6,000. At the 12% marginal rate, this saves approximately $720 in federal income tax. Additionally, the lower AGI may reduce the taxable portion of her $22,000 in Social Security benefits, creating further savings.
Patricia's MAGI of $26,260 (calculated before the senior deduction) is below the $75,000 phase-out threshold, so she receives the full $6,000.
When the offset shrinks
The senior deduction becomes less effective as income rises, for two reasons:
- Phase-out reduces the deduction: MAGI above $75,000 (single) or $150,000 (MFJ) triggers a 6% reduction. Retirees with large RMDs from substantial account balances may find the deduction partially or fully eliminated.
- RMDs grow over time: As you age, the distribution period shrinks and the RMD increases (even if the account balance stays flat). A larger RMD means the $6,000 offset covers a smaller percentage of the total.
At age 73, the RMD on a $400,000 account is $15,094, so the $6,000 deduction offsets about 40% of it. By age 85, the RMD grows to $25,000, and the deduction covers only 24%.
Strategies for coordination
Retirees can take several steps to maximize the interplay between RMDs and the senior deduction:
- Qualified Charitable Distributions: QCDs satisfy RMD requirements but are excluded from gross income. By using QCDs for charitable giving, you reduce MAGI without reducing your actual cash flow, which helps preserve the senior deduction.
- Roth conversions before RMDs begin: Converting traditional IRA funds to a Roth before age 73 reduces the balance subject to future RMDs. Smaller RMDs mean lower MAGI and a better chance of staying below the phase-out threshold.
- Spreading income across years: If you have flexibility in when you recognize investment gains or take other discretionary income, coordinating those decisions with your RMD year can help manage MAGI.
