In almost every credit or debit card dispute, the merchant pays the chargeback fees. The cardholder’s bank pulls the transaction amount back from the business, and the merchant’s payment processor adds a separate administrative fee on top, typically $15 to $100 per dispute. The cardholder, under federal law, faces little or no financial exposure for a legitimate dispute. So the short answer to who pays chargeback fees is the merchant, with the cardholder’s bank acting as the collector and the card network setting the rules.
What the Merchant Loses on Each Dispute
The moment a cardholder contacts their issuing bank to dispute a charge, the bank issues a provisional credit to the cardholder’s account. That money gets pulled from the merchant through the acquiring bank, which is the financial institution that holds the merchant’s payment account. The deduction happens automatically, often before the merchant even learns a dispute has been filed. If the merchant already shipped the product or delivered the service, that’s gone too.
On top of the reversed transaction amount, the processor charges a flat chargeback fee to cover the cost of handling the dispute. The authority to pull these funds comes from the merchant services agreement every business signs when setting up payment processing. That contract gives the processor broad rights to debit the merchant’s account for dispute-related costs.
Here’s where it stings most: even when a merchant successfully proves the charge was valid, most processors keep the chargeback fee. The fee covers the labor of processing the dispute through the card network, and processors treat it as earned once the work begins. A handful of processors depart from this norm, which makes comparing fee policies worth the effort before choosing a provider.
How Much the Fee Runs by Processor
The flat fee per dispute varies significantly across processors, and the refund policy on that fee differs too:
- PayPal charges $20 per chargeback on transactions processed outside its own checkout. For transactions processed through a buyer’s PayPal account, the standard dispute fee is $15, rising to $30 for merchants with high dispute volume.1PayPal. Fees | Merchant and Business | PayPal US
- Stripe charges a per-dispute fee with a “dispute received” component and a “dispute countered” component. Stripe returns the countered fee if the merchant wins, but the received fee is non-refundable for U.S. businesses regardless of outcome.2Stripe Documentation. How Disputes Work
- Square charges no chargeback fee at all. It absorbs the dispute processing cost, though it still debits the disputed transaction amount from the merchant’s balance during the investigation.3Square Support Center. Manage Payment Disputes
Businesses that processors classify as high-risk, including industries like travel, supplements, and digital goods, typically face fees at the upper end of the range. Some high-risk processors charge $100 or more per dispute. The risk classification also affects the processing rate on every transaction, not just disputed ones, so chargebacks create a compounding cost problem.
What the Cardholder Pays on a Credit Card Dispute
Federal law caps a credit cardholder’s liability for unauthorized charges at $50, and even that applies only when a narrow set of conditions are met: the card must be an accepted card, the issuer must have provided notice of potential liability, and the unauthorized use must have occurred before the cardholder reported the problem.4Office of the Law Revision Counsel. 15 USC 1643 – Liability of Holder of Credit Card In practice, nearly every major issuer waives the $50 as a competitive perk, giving cardholders zero-liability protection on unauthorized credit card charges.
For billing errors and disputes over goods or services, the resolution process established by Regulation Z costs the cardholder nothing to initiate.5eCFR. 12 CFR Part 226 – Truth in Lending (Regulation Z) The issuing bank investigates at no charge and provides a provisional credit during the investigation. If the bank sides with the merchant, the provisional credit is reversed and the cardholder owes the original amount.
What the Cardholder Pays on a Debit Card Dispute
Debit cards offer weaker protection, and the timing of the cardholder’s report drives everything. Under the Electronic Fund Transfer Act, liability depends on how quickly the cardholder notifies their bank after discovering the unauthorized charge:
- Within 2 business days: liability capped at $50
- Between 2 and 60 days: liability rises to $500
- After 60 days: no cap. The cardholder can be liable for the full amount of unauthorized transfers that occur after the 60-day window
The two-day clock starts when the consumer learns of the loss or theft, not when the unauthorized charge posts.6Consumer Financial Protection Bureau. Regulation E – 1005.6 Liability of Consumer for Unauthorized Transfers Regulation E also requires the bank to issue provisional credit within 10 business days of a report, but if the investigation later determines the charge was authorized, that credit gets pulled back. The gap between credit card and debit card protections is one reason personal finance advisors consistently recommend using credit cards rather than debit cards for purchases.
When Cardholders Face Consequences
Filing a legitimate dispute costs the cardholder nothing, but abusing the process carries real risks. Banks track dispute frequency internally, and patterns that look like friendly fraud, meaning disputes over products the customer actually received, can trigger account reviews. Some banks begin flagging accounts after as few as two or three disputes in a short period, and account closure can happen without advance notice. There is no universal threshold; each bank sets its own tolerance based on dollar amounts, dispute outcomes, and overall account history.
Costs Beyond the Per-Dispute Fee
The flat chargeback fee is only the most visible cost the merchant pays. Several other layers can hit the same business.
Reserves. Payment processors frequently impose reserve requirements on merchants they consider high-risk. A rolling reserve holds back a percentage of each day’s deposits, typically 5% to 10%, for six months before releasing the funds. A capped reserve works similarly but stops withholding once the total reaches a set dollar amount. Either way, the merchant loses immediate access to a meaningful slice of revenue.
Network monitoring assessments. Card networks track each merchant’s chargeback ratio and charge extra when it crosses a threshold. Under Visa’s Acquirer Monitoring Program, merchants flagged as “excessive” pay $8 per fraud report and dispute, and a lower tier charges $4 per transaction. These assessments stack on top of the processor’s own chargeback fee.
Arbitration. If a dispute escalates past representment through pre-arbitration into full arbitration, the losing party pays the network’s filing fee. Visa’s case filing fee for arbitration rose to $600 in April 2025, and Mastercard charges $400 for the same process. Visa also charges a $5,000 appeal fee, refundable if the appeal succeeds.7Visa. Visa Core Rules and Visa Product and Service Rules For a merchant disputing a $30 transaction, these numbers price arbitration out of reach.
The MATCH list. Mastercard maintains a database of terminated merchants shared across the payment processing industry. A merchant gets added when their Mastercard chargeback count exceeds 1% of sales transactions in any single month and those chargebacks total $5,000 or more. Landing on MATCH makes it extremely difficult to get approved for a new merchant account with any processor for five years.8Stripe Documentation.

Tax Treatment of What the Merchant Pays
Chargeback losses and the associated fees are generally deductible as ordinary business expenses. The IRS treats chargeback reimbursements either as a reduction in gross receipts or as a deductible expense, and the timing follows the “all events” test: the loss is deductible in the tax year when the liability becomes fixed and determinable, even if actual payment happens the following year, provided payment occurs within eight and a half months of the close of that tax year.9Internal Revenue Service. Deduction for Chargeback Reimbursement Accrued Expense
For businesses on cash-basis accounting, the deduction is simpler: the loss is deductible in the year the chargeback is actually debited from the account. Keeping detailed records of every chargeback, including the processor’s fee statement and the outcome of any representment, makes the deduction straightforward to document at tax time.
