Qualified Charitable Distribution (QCD) Calculator

The IRS updates the rules and limits for charitable distributions periodically. In 2024, the IRS began indexing the annual limit for inflation, raising it from the long-standing $100,000 cap.

Many retirees withdraw cash from their IRA, deposit it into their checking account, and then write a check to a charity. While this feels straightforward, it is highly tax-inefficient.

When you withdraw cash from a traditional IRA, that amount is added to your AGI. To get a tax benefit for donating that cash, you must itemize your deductions. However, the 2026 standard deduction is high—$15,200 for single filers and $30,400 for married couples filing jointly (plus additional amounts for being over 65). Most retirees do not have enough deductible expenses to exceed these thresholds, meaning they get zero tax benefit for their cash donation.

A QCD solves this problem. The money moves directly from your IRA custodian to the charity. It never touches your checking account, and more importantly, it never touches your AGI.

By keeping your AGI lower, a QCD provides "above-the-line" benefits that a standard itemized deduction cannot offer:

• Lower Medicare Premiums: Medicare Part B and Part D premiums are tied to your AGI through the Income-Related Monthly Adjustment Amount (IRMAA). A lower AGI can keep you out of higher premium surcharge tiers.
• Reduced Social Security Taxation: Up to 85% of your Social Security benefits can be taxed if your provisional income crosses certain thresholds. Keeping IRA withdrawals off your tax return helps minimize this tax hit.
• More Favorable Medical Deductions: If you do itemize, you can only deduct medical expenses that exceed 7.5% of your AGI. A lower AGI makes it easier to cross that threshold.

For a broader look at how giving fits into your monthly cash flow, you can use the charitable giving retirement budget calculator.

This calculator determines your eligibility, limits your maximum allowed distribution, and computes your tax savings based on federal brackets and state tax rates.

The calculator applies these primary formulas:

Allowed QCD Amount = min(Desired Donation, IRA Balance, Annual QCD Limit)

Where:

• Desired Donation = The dollar amount you want to give to charity this year.
• IRA Balance = Your total traditional IRA assets available for withdrawal.
• Annual QCD Limit = The IRS maximum for the current tax year ($108,720 in 2026).

To determine how the donation affects your required distributions, the formula is:

RMD Satisfied by QCD = min(Allowed QCD Amount, Calculated RMD)

Where:

• Allowed QCD Amount = The eligible transfer amount calculated above.
• Calculated RMD = Your total required withdrawal for the year, based on your age and the IRS Uniform Lifetime Table.

Finally, your tax savings are calculated by comparing your tax liability with and without the charitable distribution:

Total Tax Savings = (Tax Without QCD - Tax With QCD) + State Tax Savings

Where:

• Tax Without QCD = Federal tax calculated on your total income including the full RMD.
• Tax With QCD = Federal tax calculated on your total income excluding the portion of the RMD satisfied by the QCD.
• State Tax Savings = The Allowed QCD Amount multiplied by your estimated state income tax rate.

The most common use case for a QCD is to satisfy a Required Minimum Distribution without paying taxes on it. If you are 73 or older, the IRS forces you to withdraw a specific percentage of your pre-tax retirement accounts each year.

If you do not need this money for living expenses, being forced to take it can push you into a higher tax bracket. A direct charitable transfer counts toward your RMD for the year, up to the $108,720 limit.

However, timing is critical due to the IRS "first dollars out" rule. The IRS considers the first money withdrawn from your IRA during the calendar year to be your RMD.

If your RMD is $10,000, and you withdraw $10,000 in cash in January to pay for a vacation, your RMD is satisfied. If you later decide to do a $10,000 QCD in November, that transfer will still be tax-free, but it will be in addition to the taxable $10,000 you already withdrew. To effectively offset your RMD, you must execute the charitable transfer before you take your full RMD in cash.

To explore different withdrawal orders and their tax impacts, review the retirement withdrawal calculator or read our guide on how to reduce taxes on required minimum distributions.

There is a unique planning window between age 70½ (when you become eligible for QCDs) and age 73 (when RMDs currently begin).

During these "gap years," you are not required to take money out of your IRA. However, if you are charitably inclined, making distributions during this window is a highly effective strategy. Every dollar you transfer to charity at age 71 or 72 permanently removes that money from your IRA, which means it will never be subject to future RMD calculations.

By proactively shrinking your IRA balance before age 73, you reduce the size of your forced taxable withdrawals later in your 70s and 80s. This is an excellent complement to other tax-reduction strategies, such as utilizing a Roth conversion calculator to shift assets into tax-free accounts during low-income years.

Not every charitable organization qualifies for a direct IRA transfer. To receive the tax benefit, the receiving organization must be a 501(c)(3) public charity.

You cannot use a QCD to fund:

• Donor-Advised Funds (DAFs)
• Private foundations
• Supporting organizations
• Charitable Remainder Trusts (with a limited one-time exception of $53,000 under the SECURE 2.0 Act)

Additionally, the funds must come from an eligible account. Traditional IRAs and inherited IRAs are the most common sources. If you inherited an IRA from a parent or spouse, you can make a QCD from it, provided you (the beneficiary) are over age 70½. You can project the rules for these specific accounts using the inherited IRA distribution calculator or the inherited Roth IRA RMD calculator.

You cannot make a QCD directly from a 401(k) or 403(b). If your money is in an employer plan, you must first roll it over to a traditional IRA, and then initiate the charitable transfer from the IRA.

To understand the financial impact, consider a 75-year-old single retiree with a $600,000 IRA balance and $45,000 in other taxable income (from a pension and taxable Social Security). They want to donate $10,000 to their local food bank this year.

Based on the IRS Uniform Lifetime Table, a 75-year-old has an RMD divisor of 22.9. This means their calculated RMD is roughly $26,200 ($600,000 ÷ 22.9).

Here is how their tax situation changes depending on how they make the donation:

Note: In Option A, the retiree cannot deduct the $10,000 cash donation because it does not exceed the $15,200 standard deduction.

By choosing Option B, the retiree satisfies their full $26,200 RMD obligation but only pays taxes on $16,200 of it. This lowers their AGI by $10,000, saving them approximately $2,200 in federal income taxes. Furthermore, keeping their AGI at $61,200 provides a larger buffer against Medicare IRMAA surcharges, which begin at higher income thresholds.
