Navigating the RMD Engine: Statutory Divisors & MAGI Impacts

Six inputs cards. One click. A complete picture of your required minimum distribution, tax pressure, QCD opportunity, and inherited-account strategy.

📥
1

Reconcile Account Balances & IRS Filing Status

Input your prior year-end IRA or 401(k) balance, your current age, account type, and the correct IRS life-expectancy table. The calculator uses these to look up your official distribution period factor.

🧮
2

Apply the IRS Uniform Lifetime Table Divisor

Your RMD equals your account balance divided by the IRS life-expectancy factor for your age. The workbench uses the IRS Uniform Lifetime Table, Joint & Last Survivor Table, or Single Life Table depending on your situation.

💸
3

Execute Qualified Charitable Distribution (QCD) Offsets

If you enter a Qualified Charitable Distribution amount, the calculator subtracts it directly from the RMD before any tax is calculated. This is the most tax-efficient use of the RMD — it satisfies the distribution while keeping the amount out of your AGI entirely.

📊
4

Quantify Federal Tax Friction & Safe Harbor Withholding

The taxable portion of your RMD is added to your other income and Social Security to estimate your approximate AGI. The tool then applies your marginal federal bracket, state rate, and the provisional income formula to flag Social Security tax exposure.

🏥
5

Stress-Test MAGI for IRMAA & Provisional Income

If IRMAA sensitivity is enabled, the calculator compares your estimated MAGI against Medicare Part B and Part D premium surcharge thresholds. It flags Low, Watch, Elevated, or High risk — because a single extra dollar of income can push you into the next IRMAA bracket.

Generate Fiduciary Verdict & RMD Action Plan

The workbench scores five issue types — tax spike, IRMAA risk, QCD opportunity, first-year double-RMD timing, and inherited-account complexity — then surfaces the dominant problem as your main planning issue with a plain-English recommendation.

📐 Core Actuarial & IRC-Validated Tax Formulas

Annual RMD RMD = Prior Year-End Account Balance ÷ IRS Life-Expectancy Factor (age-based)
Taxable RMD after QCD Taxable RMD = RMD − MIN(QCD amount, RMD) → QCD is capped at the full RMD
Provisional Income (SS Tax) Provisional Income = Other Income + Taxable RMD + (Social Security × 50%) → if > $25K single / $32K MFJ, SS becomes partly taxable
Approximate AGI AGI ≈ Other Income + Taxable RMD + Extra Withdrawal + SS Taxable Portion
Federal Tax on RMD Federal Tax = Total Taxable Withdrawal × Marginal Federal Bracket Rate (at estimated AGI)
Withholding Estimate Withholding = Total Taxable Withdrawal × Your Withholding Rate %
IRMAA MAGI Threshold IRMAA Risk = Compare AGI vs. IRS thresholds → Low (<$106K single) / Watch / Elevated / High (>$500K single)
First-Year Double RMD Risk If First RMD Year = Yes AND Delay to April = Yes → Double RMD Pressure = RMD × 2 in one calendar year

📖 IRS Uniform Lifetime Table: 2026 Statutory Actuarial Divisors

Your RMD = account balance ÷ the factor below. A lower factor means a larger required distribution as a percentage of your balance.

Source: IRS Publication 590-B, Uniform Lifetime Table (post-SECURE 2.0, effective 2022). For a spouse more than 10 years younger, use the Joint & Last Survivor Table, which produces a larger factor and a smaller RMD. For inherited IRAs with non-spouse beneficiaries, the Single Life Table applies and factors are significantly shorter.

Required Minimum Distributions (IRC Section 401(a)(9))

A Required Minimum Distribution is the minimum amount the IRS forces you to withdraw annually from tax-deferred retirement accounts — Traditional IRAs, SEP-IRAs, SIMPLE IRAs, and most workplace plans like 401(k)s and 403(b)s — once you reach RMD age.

The SECURE 2.0 Act raised the RMD starting age to 73 for anyone who turned 72 after December 31, 2022, and it will rise again to 75 for those born in 1960 or later. Roth IRAs are exempt from RMDs during the original owner’s lifetime.

  • RMD age is 73 for most people as of 2024
  • Rising to age 75 for those born in 1960 or later
  • Roth IRA owners are exempt from lifetime RMDs
  • Employer Roth accounts lost their RMD exemption after SECURE 2.0
  • RMDs are fully taxable as ordinary income (no capital gains rate)

Qualified Charitable Distributions (QCD) & AGI Compression

A Qualified Charitable Distribution lets you transfer money directly from your IRA to a qualifying 501(c)(3) charity. The critical tax advantage: the distribution counts toward satisfying your RMD but is excluded entirely from your taxable income — it never touches your AGI.

This makes a QCD far more valuable than taking the RMD, paying tax on it, and then donating the after-tax cash. The QCD reduces AGI, which can lower your tax bracket, reduce the taxable portion of Social Security, and keep you below IRMAA thresholds.

  • Maximum QCD is $105,000 per person per year (2024, indexed for inflation)
  • You must be age 70½ or older to make a QCD
  • Must go directly from IRA custodian to the charity — no personal receipt
  • Does not require itemizing deductions to benefit
  • Cannot be made to donor-advised funds or private foundations
⚠️

Required Beginning Date (RBD) & The Double-RMD Trap

In your first RMD year, you have a one-time option to delay your distribution until April 1 of the following year. This sounds helpful, but it is almost always a tax trap. If you delay, you must still take your second year RMD by December 31 of that same year — meaning two full RMDs land in one calendar year.

Two RMDs in a single year can push you into a higher tax bracket, make more of your Social Security taxable, trigger IRMAA surcharges, and reduce eligibility for certain credits. In most cases, taking the first RMD on time avoids this entirely.

  • April 1 deadline applies to the first RMD year only
  • All subsequent RMDs must be taken by December 31
  • Double-RMD years frequently cause surprise tax bills
  • Withholding in a double-RMD year is often badly miscalculated
  • Run this calculator with the delay toggle ON to see your exposure

IRMAA (Income-Related Monthly Adjustment Amount) MAGI Cliffs

IRMAA stands for Income-Related Monthly Adjustment Amount. If your MAGI from two years prior exceeds certain thresholds, Medicare charges you a surcharge on top of the standard Part B and Part D premiums. For 2024, the surcharge ranges from an extra $70/month all the way to $419/month per person.

What makes IRMAA dangerous for RMD planning is the cliff effect: exceeding a threshold by even one dollar pushes your entire premium into the next bracket. A large RMD can unexpectedly trigger thousands of dollars in additional Medicare costs that persist for two years after the income spike.

  • IRMAA is based on MAGI from 2 years prior (so 2024 income affects 2026 premiums)
  • Single filer threshold: $106,000 MAGI to avoid any surcharge (2024)
  • MFJ threshold: $212,000 MAGI to avoid any surcharge (2024)
  • Cliff brackets mean $1 over can cost $1,000+ per year in extra premiums
  • QCDs reduce MAGI and are the primary tool to avoid IRMAA bracket creep

The 10-Year Rule for Non-Eligible Designated Beneficiaries

Non-spouse beneficiaries who inherited an IRA after January 1, 2020 are subject to the 10-year rule — the entire account must be emptied by the end of the 10th year following the original owner’s death. There are no required annual distributions, but many beneficiaries still take annual withdrawals to spread the tax burden.

Eligible designated beneficiaries — including surviving spouses, disabled individuals, chronically ill individuals, and minor children — may still use the old stretch IRA rules based on their own life expectancy. Spouses have the most flexibility, including the ability to roll the inherited IRA into their own IRA entirely.

  • 10-year rule applies to most non-spouse beneficiaries post-2019
  • No annual RMD required under 10-year rule (but entire account must be depleted)
  • Spouse beneficiaries can roll over into their own IRA and delay RMDs to their own age
  • Minor children use stretch rules until age of majority, then 10-year rule kicks in
  • IRS proposed regulations on annual distributions for inherited IRAs are still evolving

Social Security Provisional Income Limits (The 85% Tax Threshold)

Up to 85% of your Social Security benefits can become taxable depending on your “provisional income” — a formula that adds your adjusted gross income, tax-exempt interest, and 50% of your SS benefits together. Once your RMD pushes provisional income above the threshold, more of your SS gets pulled into taxable income, creating a compounding tax effect.

For a single filer in 2024, once provisional income exceeds $34,000, up to 85% of Social Security is taxable. Because RMDs are counted in full in the provisional income formula, a larger RMD can dramatically increase the tax on SS income you thought was protected.

  • 50% of SS is taxable when provisional income exceeds $25K single / $32K MFJ
  • 85% of SS is taxable when provisional income exceeds $34K single / $44K MFJ
  • RMDs count dollar-for-dollar in provisional income
  • QCDs reduce AGI, which reduces provisional income and SS taxation
  • Unlike most tax thresholds, these base amounts are not indexed for inflation

Best use caseCharitable intent + tax minimizationPersonal spending needs
Pro Tip: Even if you don’t normally donate to charity, a QCD can be strategically useful to reduce AGI, stay below an IRMAA threshold, or keep more of your Social Security income from being taxed. The tax savings can sometimes exceed the value of the charitable gift itself.
⚠️ Missed RMD Penalty: Failing to take your full RMD by the deadline triggers an IRS excise tax of 25% of the amount not distributed (reduced from 50% by SECURE 2.0). If corrected within two years under the new Self-Correction program, the penalty drops to 10%. Always verify your exact RMD with your custodian — this calculator is a planning estimate only.
⏰ Important Deadlines: The RMD deadline is December 31 each year. Only your first RMD can be delayed to April 1 of the following year — and doing so means two RMDs in one tax year. All subsequent RMDs must be completed by December 31 with no exceptions.
✅ Aggregation Rule: If you own multiple Traditional IRAs, you can calculate each account’s RMD separately but satisfy the total combined RMD from any one or combination of your IRAs. This gives you flexibility to strategically draw from accounts with different investment compositions. However, 401(k) RMDs must be taken separately from each plan — they cannot be aggregated with IRA RMDs.
💡 Withholding Tip: IRA custodians typically default to 10% federal withholding on RMD distributions. If your effective rate is higher — which is common when RMDs push AGI into the 22%–24% bracket — under-withholding throughout the year can result in underpayment penalties. Consider requesting a higher withholding rate (20%–30%) or making estimated tax payments to cover the gap.

💡 Key Takeaway: Margaret donates to her church every year anyway. By routing $12,000 of that gift directly through her IRA as a QCD instead of taking the RMD in cash and then donating, she removes $12,000 from her AGI entirely. This keeps her provisional income below the threshold where 85% of Social Security becomes taxable — saving her approximately $3,400 in combined federal and state tax versus taking the full RMD as a taxable withdrawal. She still gives the same amount to charity. The only change is the order of operations.

💡 Key Takeaway: Robert has both a Traditional IRA and an old employer 401(k) — a very common situation for retired corporate workers. The critical planning point: IRA and 401(k) RMDs cannot be aggregated. He must take the 401(k) RMD directly from that plan and separately satisfy the IRA RMD. However, if he rolls the old 401(k) into his IRA before year-end, all future RMDs can be taken from a single account. With $58,000 in combined Social Security, their provisional income already exceeds $44,000, making 85% of all SS income taxable — a $49,300 invisible tax increase that most retirees don’t anticipate when they see their first RMD statement.

💡 Key Takeaway: David’s large IRA balance produces a $95,455 mandatory RMD — even with a $25,000 QCD, his estimated AGI of $191,200 pushes him into the IRMAA “Elevated” bracket, triggering an extra $297/month in Medicare Part B surcharges starting two years later. The most powerful move David could have made was aggressive Roth conversions in his late 60s before RMDs began, when his income temporarily dropped after leaving his medical practice. Every $100,000 converted at age 67 at a 24% rate would have permanently reduced his annual RMD by roughly $4,500 — and kept his MAGI below the IRMAA cliff. This example illustrates why IRMAA planning must begin years before Medicare enrollment, not after the first RMD arrives.

💡 Key Takeaway: Susan’s financial advisor mentioned that she could delay her first RMD to April 1 of next year. On paper it sounds helpful — one more year of tax-deferred growth. In practice, it is almost always a trap. Delaying forces two full RMDs into the same calendar year: the delayed Year 1 distribution by April 1 and the Year 2 distribution by December 31. For Susan, this compresses $27,196 of RMD income into a single year, pushing her AGI high enough to make 85% of her Social Security taxable and bumping part of her income into the 22% bracket — costing her an extra $3,110 in federal tax she would not have owed by simply taking the Year 1 RMD on time in December. Tennessee has no state income tax, so at least she avoids that additional cost.

💡 Key Takeaway: James inherited his father’s Traditional IRA in 2021 and is now in Year 4 of his 10-year mandatory distribution window. He is not required to take annual distributions — the only rule is that the account must be fully emptied by December 31 of Year 10 (2031). However, James earns $145,000/year. If he waits until Year 10 and takes the full remaining balance (projected at ~$218,000 with growth) as a single lump sum, it will push his AGI above $363,000 — landing him firmly in the 32%–35% federal bracket and costing an estimated $69,760 in federal tax on that distribution alone. By spreading $30,000/year across the remaining 6 years instead, he pays tax at his current 22% marginal rate and saves approximately $43,000 in federal tax over the window. At 48, he is also not yet eligible for QCDs, making income-spreading the only real tax lever available to him.

❓ Fiduciary FAQ: SECURE Act 2.0 Benchmarks, Inherited IRAs & Penalties

You have satisfied your RMD requirement and then some. There is no penalty for taking more than the minimum. The excess simply increases your taxable income for the year. You cannot carry the excess forward to reduce a future year’s RMD — each year’s RMD is calculated fresh from that year’s prior December 31 balance.
Yes, if you have earned income and meet Roth IRA contribution limits ($7,000 per year in 2024, $8,000 if age 50+). You take the RMD, pay the tax, and then contribute up to the limit back into a Roth IRA. This strategy effectively converts taxable IRA money to tax-free Roth money over time, though the full RMD is still taxable in the year taken.
Yes, but the order matters. Withdrawals from an IRA are treated as satisfying the RMD first. So if you take a taxable distribution equal to your full RMD before making a QCD, the QCD no longer satisfies the RMD — it counts as an additional charitable distribution but does not reduce your already-satisfied RMD. To get the full tax benefit, make the QCD before or instead of taking the taxable RMD withdrawal.
Each year you age by one, the IRS factor decreases by approximately 0.9 to 1.0 — meaning a slightly higher percentage of your account must be distributed. For example, the factor at age 73 is 26.5, and at age 74 it is 25.5. This means your RMD percentage rises from about 3.77% of balance at 73 to about 3.92% at 74, and continues increasing gradually each year, accelerating in your 80s and beyond.
No. QCDs can only be made directly from an IRA — not from 401(k), 403(b), or other employer-sponsored retirement plans. If you want to use your 401(k) balance for a QCD, you would first need to roll it over into a Traditional IRA, and then initiate the QCD from the IRA. There is no waiting period after a rollover before you can make a QCD.
IRMAA uses your MAGI from two years prior to determine your current-year Medicare premium surcharge. So a large RMD you take in 2024 will affect your 2026 Medicare Part B and Part D premiums. This two-year lag means you need to plan ahead — if you know a large Roth conversion or inherited IRA distribution is coming, consider the IRMAA impact two years downstream and use QCDs or income smoothing to stay below thresholds.
Often not. The default IRA withholding rate of 10% is frequently too low for retirees with Social Security, pension income, and RMDs combined — especially if the RMD pushes AGI into the 22% or 24% federal bracket. You can request any withholding rate you want from your custodian, or make quarterly estimated tax payments (Form 1040-ES) to cover the gap. A year-end RMD taken in December can also be a convenient time to request a large one-time withholding to settle your full tax bill.
You can take your RMD in any number of distributions throughout the year — monthly, quarterly, a single lump sum, or any combination — as long as the total amount withdrawn equals or exceeds the full RMD by December 31. Many retirees prefer monthly distributions to smooth out cash flow and withholding. Others take a single distribution in December after reviewing their full tax picture for the year. The IRS only cares about the total amount by year-end, not the timing within the year.
Your RMD is always based on your account balance as of December 31 of the prior year — not the current value. So if your account dropped 30% in value during the current year, you are still required to distribute the amount calculated from last December 31’s balance. The one exception was the CARES Act of 2020, which waived RMDs for that year only due to COVID-19. There is no standing provision that adjusts RMDs for mid-year market losses, which is why some advisors recommend taking the RMD early in the year when balances are higher, or later after markets may have recovered.
Yes — for Traditional IRAs, SEP-IRAs, and SIMPLE IRAs owned by the same individual, you calculate the RMD separately for each account but can satisfy the combined total from any one or more of those IRAs. This is called the IRA aggregation rule. It gives you strategic flexibility to draw from whichever account makes the most sense — for example, depleting a lower-performing account first or preserving a Roth-converted account. However, 403(b) RMDs can only be aggregated among 403(b) accounts, and 401(k) plans must be distributed from each plan separately. IRAs and 401(k)s cannot be aggregated together.
Yes, and this is one of the most powerful long-term RMD planning strategies available. Every dollar you convert from a Traditional IRA to a Roth IRA reduces the balance subject to future RMDs. Because Roth IRAs are not subject to RMDs during the original owner’s lifetime, the converted amount grows tax-free and will never force a distribution. The trade-off is that you pay ordinary income tax on the converted amount in the year of conversion. The ideal window for Roth conversions is typically between retirement and age 73 — after earned income drops but before RMDs begin — when your marginal rate may be at its lowest point of your life.
Under SECURE 2.0, the penalty for a missed or insufficient RMD is 25% of the amount that should have been distributed but was not — reduced from the previous 50%. If you correct the missed RMD within the IRS’s two-year correction window under the Self-Correction Program, the penalty drops further to 10%. To correct a missed RMD, take the required distribution as soon as possible, file IRS Form 5329 with your tax return, and request a penalty waiver by showing reasonable cause. The IRS has historically been lenient with first-time errors when they are promptly corrected — but you must file Form 5329 even if you believe a waiver will be granted.
For income tax purposes, yes — distributions from an inherited Traditional IRA are taxed as ordinary income in the year received, just like distributions from your own IRA. They are added to your gross income and taxed at your marginal rate. However, the distribution rules differ significantly: non-spouse beneficiaries subject to the 10-year rule do not have a fixed annual RMD schedule, but the entire account must be emptied by December 31 of the 10th year. You cannot roll an inherited IRA into your own IRA unless you are the surviving spouse. Inherited Roth IRA distributions are generally tax-free if the five-year holding period has been met.
Medicare Part B and Part D premiums are determined by your MAGI from two years prior. A large RMD in 2024 will affect your 2026 premiums. If that RMD pushes your MAGI over an IRMAA threshold, your monthly Part B premium can jump from the standard $174.70 (2024) by anywhere from $69.90 to $419.30 per person per month — translating to between $839 and $5,032 in additional annual costs per person. Because Medicare does not adjust premiums mid-year once set, a single high-income year can lock you into higher premiums for a full calendar year. This is why proactive income management in the years before and after a large RMD or Roth conversion is critical.
Yes. The $105,000 QCD limit (2024) is per person, not per household. If both spouses are age 70½ or older and each owns their own IRA, each spouse can make up to $105,000 in QCDs per year — for a combined household QCD of up to $210,000 annually. However, each QCD must come from that individual’s own IRA account. A spouse cannot make a QCD from their partner’s IRA. This makes the QCD one of the few retirement strategies where married couples get a true doubling of the benefit on a per-person basis.
If you are still actively employed and participating in your current employer’s 401(k) plan, and you do not own more than 5% of the company, you may be able to delay RMDs from that specific employer plan until you retire — even past age 73. This is called the still-working exception. However, this exception applies only to your current employer’s plan. Any IRAs you own and any 401(k)s from previous employers are still subject to RMDs starting at age 73, regardless of your employment status. Rolling an old employer 401(k) into your current employer’s plan may allow you to defer those RMDs as well, if the plan accepts incoming rollovers.
Yes. You can take your RMD as an in-kind distribution of securities — transferring shares of stock or mutual funds from your IRA to a taxable brokerage account instead of liquidating them for cash. The fair market value of the shares on the date of transfer counts toward satisfying your RMD. The full value is taxable as ordinary income in the year of the distribution. The advantage is that once in your taxable account, any future appreciation is taxed at the lower long-term capital gains rate rather than ordinary income rates. This strategy, sometimes called a “stock distribution RMD,” works well for highly appreciated positions you want to continue holding.
If you made non-deductible contributions to your Traditional IRA and have tracked them using IRS Form 8606, a portion of each distribution — including RMDs — is tax-free. The tax-free portion is calculated using the pro-rata rule: you divide your total basis (after-tax contributions) by the total value of all your Traditional IRAs combined. For example, if your total IRA basis is $50,000 and your total IRA value is $500,000, then 10% of every distribution is tax-free. The remaining 90% is ordinary income. This calculation must be done annually and reported on Form 8606. Many retirees are unaware they have basis in their IRAs, especially from years of non-deductible contributions, which can meaningfully reduce the taxable portion of RMDs.
No. Donor-advised funds do not qualify as eligible recipients for a Qualified Charitable Distribution. The IRS explicitly prohibits QCDs to DAFs, private foundations, and supporting organizations under IRC 509(a)(3). To satisfy your RMD and get a tax benefit, you must direct the QCD to a public charity that is a 501(c)(3) organization — such as a university, hospital, religious organization, or other qualifying nonprofit. If you want to use a DAF for charitable giving, you would need to take the RMD as a taxable distribution, pay the tax, and then contribute cash to your DAF separately — which is less tax-efficient than a direct QCD to a qualifying charity.
RMDs can trigger a significant hidden tax on Social Security because of how provisional income is calculated. Your provisional income equals your adjusted gross income plus tax-exempt interest plus 50% of your annual Social Security benefit. Every dollar of RMD income adds a dollar to provisional income. Once provisional income exceeds $34,000 for single filers or $44,000 for married filing jointly, up to 85% of your Social Security becomes taxable. For a retiree with $30,000 in Social Security, that could mean as much as $25,500 of additional taxable income — purely as a result of the RMD. A QCD can reduce this effect by keeping the RMD out of your AGI entirely, which keeps provisional income lower and shields more of your Social Security from tax.
It depends on your state. Twelve states — including Illinois, Mississippi, and Pennsylvania — fully exempt retirement income including IRA distributions and RMDs from state income tax. Several other states offer partial exemptions or deductions up to a certain dollar amount. States with no income tax at all, such as Florida, Texas, Nevada, Tennessee, and Wyoming, naturally impose no state tax on RMDs. High-tax states like California and New York, however, tax IRA distributions as ordinary income at rates up to 13.3% and 10.9% respectively. This makes state of residence a significant factor in retirement income planning — some retirees time their move to a lower-tax state to coincide with when their RMDs begin.
A QLAC is a type of deferred income annuity purchased inside a Traditional IRA or 401(k) that allows you to postpone distributions — and the associated taxes — until as late as age 85. The SECURE 2.0 Act increased the QLAC contribution limit to $200,000 (up from the prior $135,000 limit or 25% of account balance). Because the QLAC premium is excluded from your RMD calculation each year, purchasing a QLAC effectively reduces your annual RMD by removing that portion of your IRA balance from the calculation. The annuity then begins paying income at the elected start date (which can be deferred up to age 85), guaranteeing you cannot outlive that portion of your retirement savings. QLACs are best suited for retirees who want to reduce near-term taxable income while ensuring late-life income security.
Your IRA custodian will send you Form 1099-R reporting the total gross distribution from your IRA — this includes both the taxable portion and any QCD amount. The full gross distribution typically appears on Line 4a of Form 1040 as the total IRA distribution. For the taxable amount on Line 4b, you subtract the QCD to show only the taxable portion. You should write “QCD” next to Line 4b to indicate the exclusion. You do not need a separate form to claim the QCD exclusion — the notation on Form 1040 is sufficient. Keep your written acknowledgment from the charity (required for all charitable donations) in your tax records. If you have non-deductible IRA basis, you will also need to file Form 8606 to calculate the taxable and non-taxable portions of your distribution.

How this tool is built, what it can and cannot do, and where every number comes from.

⚠️Not Tax or Legal Advice

This workbench is a free educational planning tool only. Nothing on this page constitutes tax advice, financial planning advice, legal advice, or investment advice of any kind. The results produced by this calculator are estimates based on simplified inputs and do not represent a filed tax return, an official RMD calculation, or a professional financial plan.

Always consult a qualified CPA, Enrolled Agent (EA), or CERTIFIED FINANCIAL PLANNER™ (CFP®) before making any decisions about IRA distributions, Roth conversions, QCD strategies, or withdrawal timing. The consequences of an incorrectly calculated RMD — including IRS excise taxes and penalties — can be significant.

📐Calculator Limitations

This tool uses simplified modeling and should not be used as a substitute for your IRA custodian’s official RMD calculation. Known limitations include:

  • ⚠️Simplified life-expectancy factors — Tables cover ages 73–92. Edge cases outside this range use the nearest available factor, which may differ slightly from your custodian’s calculation.
  • ⚠️Marginal bracket approximation — Federal tax is estimated using your marginal bracket rate, not a full progressive tax stack. Your actual tax bill will vary based on deductions, credits, and other income.
  • ⚠️IRMAA thresholds simplified — IRMAA bands are based on published 2024 thresholds and use estimated MAGI only. Actual Medicare surcharges depend on your precise prior-year MAGI as reported to SSA.
  • ⚠️Social Security taxation is estimated — The provisional income formula is modeled accurately but does not account for tax-exempt interest, AMT exposure, or state-level SS taxation rules.
  • ⚠️No non-deductible IRA basis — This tool does not calculate the pro-rata exclusion for IRAs with after-tax (non-deductible) contributions tracked on Form 8606. If you have IRA basis, your taxable RMD will be lower than this tool shows.
  • ⚠️Annual rule changes — RMD starting age, QCD limits, IRMAA thresholds, and tax brackets are adjusted each year by the IRS and CMS. Always verify current-year figures at IRS.gov before acting.
