Are Payment Processing Fees Deductible by the Donor?

Short answer: Yes. If a donor voluntarily adds an amount to cover a nonprofit's payment processing or credit card fee, the full amount paid is generally deductible as a charitable contribution—provided the donor itemizes, the organization is a qualified charity, and the donor receives no goods or services in return.

To help walk through the specifics, we turned to our resident expert for a deep dive into the underlying IRS rules and real-world application.

Clarifying tax deductions for donors

Our Ask An Expert series features real questions answered by Claire Axelrad, J.D., CFRE, our very own Fundraising Coach, also known as Charity Clairity.

Today’s question comes from a fundraiser who isn’t sure if payment processing fees are deductible by the donor.

Dear Charity Clairity, I sometimes get asked about the extent of the deductibility of donations that their donors make. Some believe that when a donor opts to cover the processing fees, that only the base donation is deductible. I know the full amount is deductible, but I have yet to find a meaningful source to cite on this. Would you be willing to provide your insight?

—Wondering

Dear Wondering,

You are correct. The full amount is deductible. The processing fee covers a piece of your overhead. It’s quite likely that some of the remaining donation covers overhead as well. You just don’t choose to itemize this for the donor. You could, but it would likely be perceived as weird.

Imagine…

“Thank you for your gift of $100, which will be used as follows:

• $77 food for distribution
• $9 Staff salaries
• $8 Administrative overhead (insurance, occupancy, utilities, technology, transportation)
• $6 (fundraising/marketing expenses)”

That would be expected by a foundation or government entity. It’s not only not expected by individual donors, but it would also likely be demotivating to the donor (although some folks might appreciate your transparency).

Regardless, ALL of the donor’s gift – whether you use it for overhead or direct service – is deductible (by a donor who itemizes deductions) — unless they receive more than a de minimis benefit in exchange. The IRS describes a de minimis benefit as “one for which, considering its value and the frequency with which it is provided, is so small as to make accounting for it unreasonable or impractical.”

A donor who gives to cover your processing fees receives no benefit from the additional fee. They’re simply making a gift that incorporates one of your ‘cost of doing business’ expenses. Deductibility is based on giving (for which nothing is given in return), not on how the charity uses the gift.

By suggesting to donors that they give more to cover your processing fees, you’re merely adding a specific element to your case for support. That is, you’re suggesting the donor restrict a portion of their gift to cover your fees. If they agree to give you more, you should thank them for the full value of what they gave to you. Whether a donor’s gift is restricted or unrestricted, it’s all deductible.

What IRS guidance applies?

If you need an authoritative source to cite to your donors or board, look no further than IRS Publication 526 (Charitable Contributions).

Publication 526 is the IRS’s comprehensive blueprint on how charitable deductions work. It clearly reinforces why a processing fee add-on is fully tax-deductible by laying out four simple rules for what makes a gift eligible:

• The gift must go to a qualified organization: The donation must be made directly to a recognized tax-exempt entity (like a 501(c)(3) public charity or religious organization). Because the full payment—including the fee portion—goes directly to your nonprofit, it meets this standard.
• The donor must itemize: To claim the charitable deduction on their federal return, the donor must itemize deductions on Schedule A (Form 1040) rather than taking the standard deduction.
• The contribution is reduced only by the value received: This is the core "quid pro quo" rule. A donor's deduction is reduced only if they receive tangible goods or services in return, such as a gala dinner, an event ticket, or a silent auction item. Covering a payment processing fee provides zero personal material benefit back to the donor; it simply helps the charity offset an administrative cost.
• The gift must be voluntarily given: The donor must make the contribution with genuine intent and without expecting a kickback. When a donor checks that box opting in to cover transaction fees, they are voluntarily increasing their total contribution.

As long as you provide a written receipt or tax acknowledgment showing the total amount received—and confirm no goods or services were provided in exchange—the donor can deduct the entire payment.

Does it matter if the fee is optional or mandatory?

Yes, absolutely. The distinction between an optional donor-covered fee and a mandatory surcharge is where many nonprofits (and their business offices) get tripped up. The core issue comes down to a fundamental rule in the tax code: a charitable contribution must be a voluntary transfer of money or property. The moment a fee loses its voluntary nature, its tax treatment changes completely.

1. Optional fees (fully tax-deductible)

When a donor completes a checkout form, checks a box to add 3% to cover processing costs, and submits the payment, they are choosing to make an additional, voluntary gift to your organization. In this scenario, the base donation and the fee combine into a single charitable contribution because the donor voluntarily gave additional money to offset your overhead without receiving any tangible benefit in return. As a result, your tax receipt should acknowledge the full combined total as deductible.

2. Mandatory fees (NOT tax-deductible)

Imagine instead a scenario where an organization's payment software requires a donor to pay a mandatory 3% transaction fee on top of their gift. Because the fee is required, it loses its status as a voluntary contribution and is treated as a service surcharge or an administrative condition of doing business. The donor can still claim their base gift, but they cannot deduct the mandatory fee itself on their tax return.

Examples: how much is deductible?

To see how these rules apply in real life, let’s walk through three distinct giving scenarios using concrete numbers.

In every case below, assume the donor itemizes their federal tax deductions and receives no goods, services, or personal benefits in exchange for their gift.

Scenario 1: The donor opts in to cover the fee.

A supporter fills out your online form to make a $100 contribution. At checkout, they check an optional box agreeing to add 3% ($3) to help offset your payment processing costs. Their credit card is billed for a total of $103.

• Base gift: $100
• Voluntary fee covered: $3
• Out-of-pocket payment: $103
• Total tax deduction: $103
• Donor tax receipt amount: $103

Because the extra $3 was entirely voluntary, it is treated as an additional charitable contribution to your general operating fund. The donor chose to give more money to support your mission, so the entire $103 is deductible.

Scenario 2: The donor pays $100, and your processor deducts the fee.

A supporter donates $100 on your website, but chooses not to cover the fee. Your payment processor charges its standard 3% transaction fee ($3), depositing a net total of $97 into your nonprofit’s bank account.

• Donor’s out-of-pocket payment: $100
• Fee retained by processor: $3
• Net amount received by charity: $97
• Total tax deduction: $100
• Donor tax receipt amount: $100

The $3 fee is an administrative expense of your nonprofit, not the donor. How your organization handles its internal backend costs doesn't change the fact that the donor voluntarily parted with $100 for a charitable purpose. Your business office records a gross donation of $100, alongside a $3 fundraising expense, and the donor receives a full $100 tax write-off.

Scenario 3: The organization charges a mandatory $3 surcharge.

A donor makes a $100 gift over the phone, but your payment system automatically adds a mandatory $3 administrative fee that the donor cannot opt out of or decline. The donor's card is charged $103.

• Base gift: $100
• Mandatory transaction fee: $3
• Out-of-pocket payment: $103
• Total tax deduction: $100
• Donor tax receipt amount: $100

Because the $3 surcharge was compulsory, it no longer qualifies as a voluntary gift. Under tax rules, mandatory surcharges are classified as service fees or administrative conditions of doing business, meaning the donor can only write off their original $100 contribution.

Your written acknowledgment should state the total voluntary contribution the donor made. If the fee was optional, receipt the full amount paid ($103). If the fee was absorbed by your organization or mandatory, receipt only the base gift ($100).

How should nonprofits receipt and account for covered fees?

Handling covered fees correctly isn’t just a matter of good donor relations. It’s also a key part of maintaining sound financial books. When a donor opts in to pay that extra 2% to 3%, both your advancement team (for tax acknowledgments) and your finance team (for ledger accounting) need to be on the same page.

Here are the steps you should take to receipt and account for covered fees:

1. Acknowledge the total gross payment

When sending tax acknowledgments or written receipts, your primary rule is simple: always acknowledge the gross total amount the donor paid to your organization.

• Acknowledge the total: If a donor makes a $100 base gift and opts in to pay $3 in processing fees, their official tax receipt should reflect a single $103 contribution.
• Itemization on receipts is optional: You do not need to explicitly separate the $100 and the $3 on the tax acknowledgment. While your online checkout form might break down the calculation for transparency during the gift flow, the formal IRS tax receipt should state that the total contribution received was $103 and that no goods or services were provided in exchange.
• Avoid net receipting: Never issue a tax receipt for the net amount settled in your bank account. Even if a processor automatically takes out a transaction fee before making a deposit, the donor is entitled to write off the full gross amount they authorized.

2. Record gross revenue vs. merchant expenses

A common question that lands on a CFO or bookkeeper’s desk is: “Should we record the net amount that hits our bank account, or the total amount the donor sent?”

Under Generally Accepted Accounting Principles (GAAP), nonprofits must use the gross reporting method rather than net expenses against revenue. Here is how that works in practice:

• Record the full contribution revenue: If a donor gives $100 plus $3 to cover fees, your accounting software should log $103 in contribution revenue.
• Record the processing fee as an expense: The merchant processing cost (say, $3.09 on the new total) is booked separately under your administrative or fundraising costs as a bank/merchant fee expense.
• Reconcile the bank deposit: The net cash deposited into your bank account (e.g., $99.91) will perfectly match your gross revenue minus the merchant fee expense.

If your finance team simply logs the net bank deposit as revenue, your organization underreports both its total fundraising revenue and its operational expenses. This distorts your financial statements and can create mismatches between your donor database (CRM) and your general ledger.

3. Confirm with your CPA or accounting team

Even though gross accounting is standard practice for nonprofits, every organization handles its chart of accounts and software setup a little differently. It’s always a good idea to sit down with your CPA or external accountant to review how your payment processor reports batch settlements. They can help make sure your merchant fee workflows line up smoothly with your Form 990 filing and annual audit needs.

Does this apply to churches and other charities?

Yes, the exact same rules apply to churches, synagogues, temples, higher education institutions, and all other 501(c)(3) qualified charities.  However, because religious organizations often have unique payroll and housing-allowance tax rules, it is always wise to double-check your specific receipting and accounting workflows with a qualified tax professional.

Frequently asked questions about tax deductions for donors

Are payment processing fees tax-deductible?

Yes, but deductibility depends on who pays. When a donor voluntarily adds money to cover processing fees, that extra amount is part of their tax-deductible charitable gift. For businesses or nonprofits paying their own processing fees, those costs are deductible as ordinary and necessary operating or fundraising expenses on their tax returns.

Are credit card fees for charitable donations deductible?

Yes. When a donor opts in to cover credit card processing fees on top of their gift, the total amount paid—including the fee portion—is fully tax-deductible. Because the donor receives no material good or service in return for covering the administrative fee, the full payment qualifies as a tax-deductible contribution to a qualified charity.

Is it illegal to charge a 3% credit card fee?

It depends on state law, card brand rules, and whether the fee is voluntary. Mandatory credit card surcharges are prohibited or heavily restricted in several states (e.g., Connecticut, Massachusetts) and capped at actual processing costs by card networks like Visa and Mastercard. However, voluntary donor opt-ins are standard, legal giving requests nationwide.

Are GoFundMe or crowdfunding donations tax-deductible?

Only if the crowdfunding campaign is organized directly by or for a recognized 501(c)(3) qualified public charity. Contributions made to personal GoFundMe campaigns—such as helping an individual with medical bills, tuition, or personal emergencies—are considered personal gifts under IRS rules and are not tax-deductible, regardless of how pressing the cause is.
