QCD vs. RMD Tax Savings Calculator (2026)

Should you take your Required Minimum Distribution and donate the cash — or send a Qualified Charitable Distribution directly from your IRA? The answer depends on whether you itemize, where your AGI lands relative to Medicare IRMAA thresholds, and how much Social Security you receive. This calculator shows the 2026 federal tax difference side by side.

What is a Qualified Charitable Distribution?

A Qualified Charitable Distribution (QCD) is a direct transfer from your IRA to a qualified public charity, authorized under IRC § 408(d)(8). ³ Two features make it uniquely powerful compared to a cash donation:

1. The amount is excluded from your gross income entirely — not merely deducted. A cash donation first adds the RMD to your income, then subtracts a deduction (only if you itemize). A QCD never enters your income at all.
2. It counts toward your Required Minimum Distribution dollar-for-dollar. If your RMD is $80,000 and you direct $50,000 as a QCD, only $30,000 remains as a taxable distribution you must take.

2026 QCD rules at a glance

• Eligible accounts: Traditional IRA, inherited IRA, inactive SEP IRA, inactive SIMPLE IRA. Does not include 401(k), 403(b), or active employer plans — you must roll to an IRA first.
• Eligible age: 70½ or older on the date of distribution.
• 2026 annual limit: $111,000 per person, up from $108,000 in 2025. Each spouse has their own $111,000 limit; a couple can collectively direct up to $222,000. ¹
• One-time election: Up to $55,000 (2026) can fund a charitable gift annuity, charitable remainder annuity trust, or charitable remainder unitrust via a special one-time QCD election.
• Eligible recipients: 501(c)(3) public charities only. Donor-Advised Funds, private foundations, and supporting organizations are not eligible QCD recipients — a common and costly mistake.
• Execution: The check must be made payable to the charity, not to you. If you receive the funds first, the distribution is taxable.
• Deadline: December 31 of the tax year. Unlike IRA contributions, QCDs cannot be made in the following year for the prior tax year.

QCD vs. RMD + donate: when each approach wins

If you normally take the standard deduction

This is where QCDs deliver the biggest advantage. If your itemized deductions (mortgage interest, SALT, etc.) fall below the 2026 standard deduction of $16,100 single / $32,200 MFJ, a cash donation gives you zero additional deduction — you've already maxed out the standard deduction. The RMD is fully taxable with no offset. The QCD is excluded from income entirely. Every dollar you donate via QCD instead of RMD saves you that dollar times your marginal rate.

If the donation is what pushes you over the standard deduction threshold

In this middle zone, you'd itemize under the RMD+donate approach (using standard deduction + donation as itemized deductions) but take the standard deduction under the QCD approach (since you can't deduct a QCD). The QCD still wins because the income exclusion is more powerful than the partial itemized deduction advantage.

If you already heavily itemize (mortgage, SALT, etc. already exceed the standard deduction)

Here the income tax difference shrinks — your charitable deduction nearly offsets the RMD income dollar-for-dollar. But the AGI advantage of the QCD remains and is often the larger benefit: lower AGI means lower Medicare IRMAA surcharges, less Social Security included in taxable income, and reduced exposure to income-based phaseouts. For HNW donors near IRMAA tier boundaries, the Medicare savings can exceed the income tax savings.

The IRMAA factor: why QCDs matter even for heavy itemizers

Medicare's Income-Related Monthly Adjustment Amount (IRMAA) adds a surcharge to your Part B and Part D premiums based on your MAGI from two years prior. The 2026 Part B surcharges are: ²

IRMAA is a cliff — one dollar over the threshold triggers the full surcharge tier. A QCD that holds your MAGI below a tier boundary saves the full annual surcharge per Medicare-enrolled spouse. IRMAA uses your MAGI from two years prior: 2026 distributions affect your 2028 Medicare premiums.

Social Security taxation: a third AGI benefit

Up to 85% of Social Security benefits become taxable when your "combined income" (AGI + nontaxable interest + ½ Social Security) exceeds $34,000 for single filers or $44,000 for married couples. These thresholds were set in 1994 and have never been adjusted for inflation — nearly every retiree with any investment income is in the 85% inclusion zone. A QCD reduces AGI, which can shift a portion of Social Security from 85% inclusion to 50% or lower, saving additional tax on top of the direct income exclusion.

How to execute a QCD correctly

1. Contact your IRA custodian (Fidelity, Schwab, Vanguard, etc.) and request a QCD distribution. Most have a dedicated form or online workflow.
2. Instruct the custodian to make the check payable to the charity directly. The check may be mailed to you for delivery to the charity, but the payee must be the charity — not you.
3. Verify the charity qualifies. Use the IRS Tax Exempt Organization Search to confirm 501(c)(3) public charity status. DAFs, private foundations, and supporting organizations are not eligible.
4. Get written acknowledgment from the charity by December 31 — same standard as any cash gift over $250.
5. Report correctly on your tax return. Your 1099-R will show the full distribution as if taxable. On Form 1040, line 4b, write "QCD" next to the taxable amount to exclude it. Tax software handles this, but verify the line when reviewing.

Common QCD mistakes that cost real money

• Distributing to yourself first. If the check is made out to you — even if you deposit and re-donate the same day — it's a taxable distribution. You lose the AGI exclusion.
• Donating to a donor-advised fund. QCDs to DAFs are expressly prohibited under current law. This is the most common mistake high-net-worth donors make when trying to combine QCDs with DAF flexibility.
• Exceeding the $111,000 limit. The excess is taxable income. The limit is per person, per year.
• Missing the December 31 deadline. No grace period. If the check hasn't cleared the charity's account by year-end, the QCD counts in the following year.
• Claiming a charitable deduction for the QCD. You cannot exclude the QCD from income and claim a deduction for it — that's double-dipping and will be disallowed on audit.
