Card surcharge ban deadlines have a way of creeping up on small builders. From 1 October 2026, Australian tradies lose the right to add 1.5% to a card payment on quoted jobs. The Reserve Bank confirmed the change in its Conclusions Paper on 31 March 2026, and the rule covers eftpos, Mastercard and Visa across debit, prepaid and credit. So that “+ 1.5% card surcharge” line at the bottom of every invoice goes.
That sounds simple. On the ground, it reshapes how every quote, deposit and progress claim gets priced. For a fencing crew taking a $25k deposit by card, the math reaches into real money. Yet most builders haven’t run the numbers. Here are six hard truths every tradie should sit with before October.
What the card surcharge ban changes
The card surcharge ban hits one specific behaviour, which is adding a percentage at checkout to recover card fees. From 1 October 2026, that path closes for the three big networks. American Express, Diners Club, BPAY and PayPal sit outside the new rule. So do BNPL services like Afterpay and Zip, though those operate under separate scheme contracts that already block surcharging.
Behind the scenes, the RBA also drops the credit interchange cap from 0.80% to 0.30% on the same day. Debit caps tighten too, from 10c to 8c. The idea is that interchange savings of around $910 million a year flow through acquirers to merchants, partly compensating for surcharge revenue you can no longer recover.
Here’s the rub. The card surcharge ban requires no new legislation. The RBA simply lifted its prohibition on the schemes’ “no-surcharge” rules, and Visa, Mastercard and eftpos now ban the practice through merchant contracts. Acquirers including Tyro, Square and Zeller have already been told to switch surcharging functionality off on the day. So the ban isn’t enforced by the ACCC against you. The schemes enforce it through your terminal provider. That distinction matters when you’re working out compliance, because it leaves the ACCC focused on disguised surcharges and misleading conduct instead.
The real economics on a tradie quote
But the maths around the card surcharge ban hits hardest at the deposit stage. Take a $25,000 fencing job with a 10% deposit. At a 1.5% surcharge, that’s $37.50 you currently recover when the customer taps. Across a 50-job year, that’s $1,875 you no longer collect. Scale it to a small builder turning over $1.2 million with half the volume on card, and you’re looking at roughly $9,000 a year of recovered surcharge revenue that disappears. Layer in progress claims and final invoices. The number gets uncomfortable fast.
Yet not all tradies feel this evenly. If you currently sit on the 16% of Australian merchants that surcharge, you carry the visible adjustment. The other 84% already absorb fees into pricing. So the card surcharge ban mostly catches hospitality, convenience and trades, which are the businesses with thin margins and unpredictable big-ticket transactions.
There’s also the cost-of-acceptance gap. Small merchants on blended single-rate plans pay roughly 1.4% per card transaction. Big merchants on negotiated unblended plans pay closer to 0.6%. The card surcharge ban arrives the same day tightened interchange caps take effect, and the regulator’s modelling suggests small merchants gain the most from the cuts, assuming savings flow through. From a cash flow perspective, this echoes the patterns I covered in my earlier piece on real-time payment rails and SMB cash flow wins, where settlement timing matters as much as the headline rate.
Where the interchange savings might go
So the card surcharge ban depends on a transmission mechanism that hasn’t always worked overseas. European data shows acquirers retained roughly 45% of interchange savings as margin, with only 45% reaching merchants. UK small businesses got even less pass-through. About 75% of Australian merchants sit on blended plans, the same cohort that fared worst in the EU experiment.
COSBOA chair Matthew Addison put the worry plainly, arguing that banning surcharges without guaranteed lower fees risks higher costs for small business. The Reserve Bank’s mitigation is transparency. Acquirers will publish quarterly pass-through measures from January 2027, and merchant statements get standardised disclosures from April 2027. There is no mandated minimum pass-through ratio.
That’s why a healthy scepticism makes sense. Tyro has publicly committed to passing on interchange savings, and its track record on least-cost routing supports that. Other acquirers have been quieter. So if you’re on a legacy bank-acquirer plan at 1.7%, the months around the card surcharge ban are the right time to renegotiate, switch or at least benchmark. The same dynamic shows up across the supply chain, as covered in construction supply chain finance and cash fixes.
What every tradie should do before October
Here’s the practical playbook. Run the last 12 months of merchant statements and calculate true blended cost-of-acceptance. Then audit any quotes with start dates after 1 October that still show a card surcharge line. Reissue them clean. Update Xero, MYOB, ServiceM8, Tradify or AroFlo to disable auto-surcharge from 1 October 2026, because some platforms toggle it off and others don’t.
But the highest-leverage move is steering deposits to PayID and PayTo. These rails settle in seconds, cost a fraction of cards, and reduce chargeback exposure on $5k to $50k deposits. So put a clean cash or bank-transfer discount on every quote above $5,000. That’s legal under both the card surcharge ban rules and ACCC component-pricing guidance, provided it’s a genuine discount on a real list price. The shift mirrors what’s happening across open banking and B2B payments, where account-to-account rails are quietly displacing card volume.
Don’t rebadge a card surcharge as a “booking fee” or “service fee” applied only to card customers. The ACCC has explicitly prebuked that move, and penalties run up to $1.16 million corporate. Genuine non-card fees like callout, weekend rate or materials handling stay legal. They just need to fold into the displayed total price.
The card surcharge ban is the start of payments reform, not the finish. Apple Pay, Google Pay, Amex and BNPL all sit outside the October package, and the RBA opens consultation on those rails in mid-2026. So treat October 2026 as the moment to clean up your card mix and tilt deposits toward A2A rails. That’s where the cash flow wins live for the rest of the decade. The card surcharge ban won’t be the last reform tradies need to navigate.
