Credit card processing for nonprofits: a practical guide

Credit card processing for nonprofits uses the same machinery any business does, pointed at donations: a merchant account or payment facilitator, card readers for events, an online donation checkout, and recurring billing for monthly givers. The differences are in the details. Visa and Mastercard publish charity interchange rates that can lower your costs, the IRS has receipt rules for larger gifts, and passing card fees on to donors carries more risk to goodwill than it does for a store.

Every dollar a processor keeps is a dollar that didn't reach your programs. Here's how to set up card giving so more of each gift lands in your bank account, with the rules that matter and the math behind them. For the setup we offer, see how Clearo helps nonprofits.

How do nonprofits accept credit card donations?

Match the tool to how your donors give. Most organizations need three or four of these:

Clearo's mobile payments cover tap to pay and card readers for events. Our virtual terminal handles phone gifts, payment links, invoices, and recurring billing, and our online payments include hosted checkout with fraud screening. If you're starting from zero, our guide on how to accept credit card payments covers the setup step by step.

One rule for staff and volunteers: never write a card number on a pledge form or in an email to run later. Send a payment link or key the gift straight into the virtual terminal, so the card goes into the payment system and nowhere else.

Do Visa and Mastercard have charity interchange rates?

Yes. Both publish charity categories in their US interchange schedules, and on credit cards they can come in well below the standard rates.

The Visa figures come from its schedule effective April 18, 2026 (Visa), and the Mastercard figures from its 2026-2027 US schedule, effective April 17, 2026 (Mastercard). Regulated debit means cards from issuers with $10 billion or more in assets, which fall under the Fed's cap of 21 cents plus 0.05%, plus 1 cent for eligible issuers (Federal Reserve).

Two caveats. First, a charity category isn't automatically the cheapest line on the schedule, as the exempt debit row shows. Second, you only get these rates if your account qualifies. Visa makes it the acquirer's job to assign the right merchant category code (Visa Merchant Data Standards Manual), and Mastercard says each of its rates has requirements that must all be met, starting with merchant category (Mastercard). Ask your processor which code your account carries and whether your donations are qualifying for the charity rates. If you run a congregation, our guide to church credit card processing covers giving at services, online, and by monthly gift.

There's a third catch, and it's the easiest to miss: the saving only reaches you if your pricing passes interchange through. On a flat rate, a cheaper interchange category widens your processor's margin and leaves your bill unchanged.

What does credit card processing cost a nonprofit?

The same three layers as any merchant: interchange to the card issuer, network fees, and your processor's markup. Here's a worked example. An animal shelter in Baltimore takes 500 online gifts a month averaging $60, or $30,000 in total. Say all 500 gifts are made on Visa consumer credit cards, which keeps the math simple.

The first two rows are interchange only, with network fees and markup on top. Even so, the gap between being coded correctly and not is $232 a month, or $2,784 a year, at this volume. For a small shelter, that's real money.

Other costs to check before you sign:

• Monthly, statement, and PCI fees, and any monthly minimum. A minimum hurts in the quiet months between campaigns.
• Gateway fees for your donation page.
• Chargeback fees, and how your processor handles disputed gifts.
• Equipment. Buy readers or rent them month to month. The FTC has warned that some businesses paid thousands to lease card equipment worth a few hundred dollars (FTC).
• Contract length and cancellation fees.

Some processors advertise a nonprofit discount. Ask for it in writing as a markup over interchange, then compare it with what the charity rates already give you. A discount off an inflated flat rate can still cost more than plain interchange-plus. Our pricing page explains how interchange-plus works.

How should nonprofits handle recurring donations?

Monthly donors are the steadiest money most organizations have, and they run on stored cards, so the rules for storing and charging cards apply.

• Get consent before you store the card. Visa's stored credential framework requires the cardholder's consent before card details are stored for future use, and the first and later charges must be identified in the transaction data (Visa).
• Get the right authorization for debit cards. Under Regulation E, preauthorized transfers from a consumer's account have to be authorized in a writing the consumer signs or similarly authenticates, and electronic signatures count (CFPB).
• Keep stored cards current. Visa says that on average, 30% of the card accounts in a participating issuer's portfolio change their number or expiration date, or close, every year (Visa). Ask your processor about account updater services.
• Never store the card security code. PCI SSC says it isn't needed for recurring transactions, and storing it for them is prohibited (PCI SSC).

Run the numbers for a food bank in Chicago with 600 monthly donors giving $25 each, or $15,000 a month. If cards change at that 30% rate, about 180 of those gifts would start failing over a year without an updater, and plenty of donors won't notice for months. Our guide to recurring billing covers retries, reminders, and cancellations in detail.

What are the IRS rules for donation receipts?

Two IRS thresholds belong in every nonprofit's receipt process:

1. Gifts of $250 or more. A donor claiming a deduction of $250 or more must get and keep a contemporaneous written acknowledgment from the charity, generally by the date they file their return for that year. It has to say whether the charity provided any goods or services in exchange, and if it did, include a good-faith estimate of their value (IRS Publication 1771).
2. Payments over $75 with something in return. When a donor pays more than $75 partly as a gift and partly for goods or services, the charity must give a written disclosure statement. The penalty for skipping it is $10 per contribution, up to $5,000 per fundraising event or mailing (IRS).

Take a donor who buys a $150 ticket to your gala in New Orleans, where the dinner is worth $60. The payment is over $75 and partly buys something, so it's a quid pro quo contribution and you owe the donor a written disclosure statement. IRS Publication 1771 explains what that statement must say.

The receipt your terminal or checkout prints usually won't cover either rule on its own, because it doesn't say whether the donor received anything in return. Send your own acknowledgment, and set up your donation page and recurring billing so the right wording goes out automatically.

Should a nonprofit pass card fees on to donors?

Not as a mandatory fee, in our view. A required fee on a gift reads like a toll on generosity, and if it applies only when a donor pays by credit card, it's a surcharge with every surcharge rule attached:

• Credit cards only. A donor paying with a Visa or Mastercard debit or prepaid card can't be surcharged.
• Capped. Visa limits a surcharge to the lesser of your merchant discount rate or 3% and requires 30 days' notice to your acquirer (Visa). Mastercard's ceiling is the lower of 4% or your organization's average effective merchant discount rate (Mastercard).
• Banned in some states. Maine, for example, bans surcharges on both credit and debit cards (Maine Legislature).

A convenience fee rarely fits a charity either. Visa describes it as a flat fee for using an alternate payment channel that differs from the merchant's normal one (Visa), and online is the main way many donors give. Our guide to the convenience fee explains the difference.

The softer alternative is an optional box that lets donors add a little to cover processing costs. Leave it unchecked by default, label it plainly, and ask your processor whether it treats that amount as part of the gift or as a surcharge, then set it up to match. If you run a thrift store or sell event merchandise, those are retail sales, and our guide to the cash discount program covers the compliant way to pass on card costs there.

Nonprofit card processing checklist

1. Map every channel: events, website, mail and phone, monthly giving, and any retail.
2. Ask your processor which merchant category code your account carries and whether your donations qualify for Visa and Mastercard charity rates.
3. Get interchange-plus pricing, so charity rates actually lower your bill.
4. Use a hosted donation page, payment links, or a virtual terminal, never card numbers on paper.
5. Turn on consent records, account updater services, and automatic receipts for recurring gifts.
6. Send written acknowledgments for gifts of $250 or more, and disclosure statements for payments over $75 that include goods or services.
7. Skip mandatory fees on donations; consider an optional, unchecked cover-the-cost box instead.
8. Avoid equipment leases, long contracts, and monthly minimums.
9. Review your statement after every big campaign.

Your next step

If your organization already takes cards, your statement shows whether your donations are getting charity rates. Send a recent one for a free statement review and we'll check the interchange categories, your effective rate, and every monthly fee. If you're setting up card giving for the first time, contact us and we'll help you plan it around your events, online gifts, and monthly donors.
