Australian retailers can no longer impose payment surcharges that exceed their actual payment processing costs. The regulation went into effect in 2022 and has since been refined through enforcement actions and industry practice. For some businesses, this barely registers. For others, it’s materially changed operating margins.

What the Rules Actually Say

The Australian Competition and Consumer Commission (ACCC) enforces rules preventing excessive surcharging. Businesses can recover the cost they actually pay for accepting a payment method, but they can’t use surcharges as profit centers or to penalize customers for card use beyond actual costs.

Credit card surcharges are capped at the merchant service fee for that transaction type. If a business pays 1.5% for Visa/Mastercard credit, it can charge customers up to 1.5%. If it charges 3%, that’s excessive and potentially subject to ACCC enforcement.

Debit card surcharges face similar restrictions but typically involve lower costs. EFTPOS transactions often cost retailers 0.5% or less, while debit Visa/Mastercard might be 0.8-1.0%. Surcharging customers 2% for debit card use when actual costs are under 1% violates the rules.

Who’s Most Affected

Small retailers with basic payment terminals often lack precise data on their per-transaction costs. They know their monthly merchant service fees and monthly transaction volume but may not know the exact percentage cost for different card types. This makes setting compliant surcharges tricky.

Airlines and travel companies historically used surcharges as revenue sources, charging customers several percentage points for credit card payments regardless of actual processing costs. Regulatory enforcement has largely eliminated this practice, reducing an ancillary revenue stream these companies had come to rely on.

Government agencies and utilities that imposed flat-dollar surcharges (e.g., “$2.50 card payment fee”) have had to recalibrate. If actual costs vary by transaction size, a flat fee that’s proportionate for large payments is excessive for small ones.

The Compliance Complexity

Merchant service fees vary by card type, transaction size, and whether the card is domestic or international. A business accepting multiple payment methods faces different costs for each. Setting surcharges that accurately reflect these varying costs is complicated.

Many businesses simplified by setting a single surcharge percentage they believe represents their weighted average cost. This approach has some regulatory risk if the surcharge exceeds costs for commonly used payment types, but ACCC enforcement has focused on egregious cases rather than minor variations.

Payment aggregators and online marketplaces create additional complexity. A business using Stripe, Square, or PayPal typically pays a blended rate covering interchange fees, scheme fees, and the aggregator’s markup. That total cost is what the business can surcharge, but explaining this to customers who see “credit card surcharge: 1.9%” and wonder why it’s higher than they expect can be challenging.

Cost Impacts on Different Business Models

High-volume, low-margin retailers like supermarkets and petrol stations rarely surcharge because the administrative complexity and customer friction outweigh the benefit. They absorb payment costs as part of operating expenses and price accordingly.

Professional services firms (accountants, lawyers, consultants) more commonly surcharge, especially for larger invoices where percentage fees add up. These businesses often have sophisticated payment systems and can track exact costs per transaction.

Online businesses face particular pressure. Payment processing for card-not-present transactions costs more than in-person payments due to higher fraud risk and interchange fees. E-commerce merchants paying 2-3% all-in costs want to recover that through surcharges but must ensure they’re not exceeding actual costs.

International Comparison

Many countries prohibit payment surcharging entirely. The European Union banned surcharges for consumer credit and debit cards in 2018. The United Kingdom has similar rules. These markets force merchants to absorb payment costs rather than passing them to customers.

Australia’s cost-recovery approach sits between full prohibition and unrestricted surcharging. It aims to let businesses recover legitimate costs while preventing excessive fees. Whether this balance works better than outright prohibition is debatable.

New Zealand allows surcharging but has voluntary codes limiting excessive fees rather than hard regulation. The practical effect is similar to Australia—most businesses that surcharge try to keep fees reasonable—but enforcement is lighter.

The Consumer Perspective

Payment surcharges frustrate customers who increasingly expect seamless digital payments without added fees. Behavioral economics research shows people react more negatively to surcharges than to equivalent price increases built into base prices.

Some businesses respond by eliminating surcharges and raising base prices slightly to cover payment costs. Customers prefer this even though they’re paying the same total amount. The transparency of surcharges creates negative perception that implicit pricing avoids.

Cash discounts represent an alternative approach—keep card prices as the advertised price and offer reductions for cash. This frames the difference positively rather than negatively. Regulatory treatment of cash discounts versus card surcharges differs in subtle ways, but the practical effect is similar.

Payment Method Innovation

Digital wallets, buy-now-pay-later services, and account-to-account payment methods all affect surcharge dynamics. Businesses need to understand the costs of each payment method and set surcharges accordingly.

Buy-now-pay-later (BNPL) services like Afterpay and Zip charge merchants higher fees than traditional card payments, often 3-6%. Merchants are contractually prohibited from surcharging BNPL transactions directly, but they absorb costs that are significantly higher than other payment methods.

Account-to-account payments via PayTo or NPP eliminate card network fees, costing merchants much less. Encouraging customers toward these methods through pricing or convenience could reduce payment processing costs more effectively than optimizing surcharge rates.

Compliance Monitoring and Enforcement

The ACCC investigates complaints about excessive surcharging but doesn’t proactively audit every business. Enforcement tends to focus on large merchants, airlines, and ticket sellers where the impact on many consumers is significant.

Small businesses face lower enforcement risk but aren’t exempt from the rules. Industry bodies recommend implementing surcharges that clearly don’t exceed costs rather than pushing limits. The reputational risk of being cited for excessive surcharging isn’t worth modest additional revenue.

Payment service providers increasingly offer tools to help merchants set compliant surcharges based on actual transaction costs. These tools reduce compliance burden but add complexity to payment processing setup.

What Businesses Should Do

Review your actual payment processing costs by transaction type. Contact your payment provider for detailed fee breakdowns if you don’t have clear data. Many merchants operate on outdated assumptions about their costs.

Set surcharges conservatively below your highest costs. If credit cards cost you 1.6% on average but occasionally spike to 1.9% for international cards, setting surcharges at 1.5% keeps you clearly compliant while recovering most costs.

Consider whether surcharging is worth the customer friction for your business. If payment costs are 1-2% of revenue and you operate on healthy margins, absorbing those costs might create better customer experience than nickel-and-diming on payment fees.

For businesses managing multiple revenue streams and complex pricing, getting strategic advice on payment optimization as part of broader business efficiency can identify opportunities beyond simple surcharge management.

The regulatory environment around payment surcharging continues evolving as payment methods diversify and consumer expectations shift. Staying compliant requires ongoing attention rather than set-and-forget surcharge policies.
