Assistant Treasurer Daniel Mulino says the federal government knew in July that the Australian Taxation Office was considering ending direct credit card payments, months before businesses were told of the plan. Shadow Treasurer Tim Wilson says that advance warning should have prompted earlier action.

Appearing on ABC’s Insiders on Sunday 18 October, Mulino said he and Treasurer Jim Chalmers were aware of the ATO’s preferred direction well before its public decision in late September. He said the government had encouraged the agency to keep negotiating with card providers and to consider a transition period.

Wilson says Labor had three months to address the risk and acted only after the business backlash. Mulino argues ministers asked the ATO to negotiate with card providers and allow time for a transition. The disagreement is about the government’s response to a possible change, not whether an ATO ban was already in force in July.

The new detail was the July warning. It had already been known that the ATO announced a plan in late September to stop taking direct credit card payments from 1 December 2026. It was also known that the government later intervened to keep the option operating for longer. Mulino’s comments provided a clearer account of how early ministers understood the problem could emerge.

On Insiders, he said the ATO was exploring options and initially favoured ceasing card acceptance. The government, according to Mulino, wanted engagement with the credit card companies rather than an abrupt change. That is the government’s account of the discussions; it does not mean a long-term solution had been reached in July.

The issue is linked to changes in how credit card surcharges are handled. The ATO would face payment processing costs if it could not pass those charges on in the same way. Negotiations with providers had not produced sufficiently low fees, according to the government’s official explanation.

The card-processing question is unusually complicated because the Australian Taxation Office is a public agency collecting compulsory payments, not a shop choosing between payment products for discretionary purchases. A merchant processing fee can look small on a single transaction, but costs scale when a taxpayer pays a large liability. If the agency cannot recover that fee through a surcharge, someone still bears it: the card provider through a negotiated rate, the tax system through public funding, or the payer through another payment arrangement. That trade-off helps explain why the dispute has drawn both business and political attention.

A credit card ban at the tax office has particular consequences for business cash flow. Some businesses use card facilities to manage timing between expenses, receipts and tax liabilities. Losing a familiar payment channel at short notice can complicate planning, even when other methods remain available.

For now, taxpayers can still pay the ATO directly by credit card. On 9 October, the government announced funding to keep the option operating until 30 June 2027. That is a temporary extension, not a promise that the existing arrangement will continue indefinitely.

The same official statement says the ATO will continue to make other payment pathways available after the transition, including certain third-party credit card arrangements as well as debit card and bank transfer options. The exact future arrangements for direct credit card acceptance have not been permanently settled by the October intervention.

The Treasury ministers’ 9 October statement also sets out what will remain after the extension. It says the ATO is expected to accept credit cards through third-party arrangements, while debit cards and bank transfers remain among available alternatives. A third-party service may not have the same charges, convenience or settlement timing as paying directly through the tax office. Taxpayers therefore should not read the extension as a guarantee that the exact direct-card experience will continue from July 2027. The government has funded additional time to work through the options, not reached a permanent settlement.

The government also asked the agency to consult further with businesses and those who may experience financial hardship. That process matters because the payment-method issue is not identical for all taxpayers. A small business with tight cash flow may have different needs from a person who can easily use a bank transfer.

Wilson’s criticism focuses on what ministers did with the warning in July. Mulino says negotiations and planning were under way before the government agreed to temporary funding. There is no verified evidence in the reports reviewed that ministers concealed a final ATO decision for months: the agency did not announce its decision until late September.

For a small business, the date tax becomes due and the date a customer pays an invoice may not line up. Some owners bridge that gap with credit, including card facilities. That does not make a tax liability smaller, but it can change the timing of money leaving the bank account. It also carries its own financial cost: interest, annual fees and any charges attached to the payment channel. Replacing a card with bank transfer could therefore remove an option for short-term liquidity while reducing some fees for other users.

The official Treasury statement provides useful perspective on the scale. It says just over two per cent of individual taxpayers and around five per cent of small businesses paid via credit card in 2024–25. Those percentages show direct card use is not the majority method, but a minority group can still be vulnerable if a short-notice change affects the way it manages working capital. The proportion of taxpayers affected is not the same as the dollar value of all transactions or the number of businesses at risk of insolvency.

The scale of the issue can be misunderstood. Treasury says a little over two per cent of individual taxpayers and about five per cent of small businesses paid by credit card in 2024–25. Those figures describe the share using the method, not the size of their tax debts or the number who need short-term borrowing to remain solvent. A payment option used by a minority can still be important if users face irregular cash receipts, but a broad claim that the policy would have crippled all Australian businesses would go well beyond the evidence.

A business with predictable monthly revenue may have no difficulty switching to a bank transfer. A building contractor waiting for milestone payments, by contrast, may rely more heavily on timing. Neither example proves that every firm in an industry uses cards the same way. What the controversy highlights is that one agency’s processing cost can become somebody else’s cash-flow problem.

The statement links the move to reforms limiting card surcharges. If a large public agency has to absorb merchant processing costs rather than recover them through a surcharge, the agency must either negotiate lower fees, find taxpayer funding or change the payment options. Those are real trade-offs; they do not automatically justify the way the original December deadline was communicated.

Taxpayers still need to meet the amount and due date on their notice, regardless of the payment method they choose. Those planning a large payment should check any card fee, interest cost and processing time directly with the ATO or their financial adviser.

ASIC warns that pressure on cash flow, overdue tax and superannuation, unpaid suppliers and reliance on personal funds can be indicators of financial difficulty. It also reminds company directors of their responsibilities to understand the company’s financial position and not incur debts when the company is insolvent. That is a broader corporate-law context, not evidence that the ATO proposal has already caused insolvencies.

The corporate-law implications are also worth separating from the headline. ASIC’s guidance on early financial difficulty lists overdue tax, unpaid superannuation, supplier arrears and reliance on directors’ own funds among the warning signs that a company may be under stress. That is a general description of cash-flow risk, not a finding that the ATO’s proposal caused those problems. Businesses already struggling with liabilities may need to seek professional advice regardless of the eventual card policy. An extra payment method is not a substitute for being able to meet obligations on time.

Credit can ease a short-term cash crunch but may become expensive if a balance cannot be repaid before interest is charged. Business owners also have to weigh the cost of financing against the consequences of leaving tax unpaid. There is no universal best payment method: a company with adequate cash reserves faces a different calculation from a sole trader with seasonal earnings. The useful response is to check the verified ATO payment options, plan ahead for due dates and get qualified advice if liabilities cannot be met.

Ahead of any due date, business owners can check the amount shown in their ATO account, the time a chosen payment method takes to process and whether the method carries a fee or credit interest. If they rely on a card to match incoming payments against outgoing tax, they can speak to an accountant about alternatives before the end of the transition. The official extension provides time to prepare but does not eliminate the need to plan.

Businesses using cards to manage working capital have until 30 June 2027 under the announced extension to consider alternatives. The temporary reprieve may ease short-term pressure, but does not settle the argument over who should pay the ongoing processing costs.

For a business owner, the decision may turn on more than whether a card technically works. Financing a tax payment can carry interest and other costs, and the benefit of keeping cash in the bank for a few weeks may disappear if a balance rolls over. Direct debit or transfer may be cheaper but less flexible for a firm waiting for a major customer to pay. The political dispute is about the absence of an orderly transition; the financial question for each business is how to match tax dates and receipts without building an expensive debt problem.

Mulino’s July disclosure has therefore created two questions for Labor: why a workable transition was not agreed sooner, and how the government intends to handle credit card payments after the extension ends.
