For many business owners, the rhythmic hum of operations depends on a delicate balancing act of cash flow. In this landscape, the ability to settle tax obligations via credit card has served as a silent, although sometimes expensive, mechanism for managing short-term working capital. It provided a vital buffer: a bridge between the date a tax liability was due and the date that payment actually cleared from the business bank account.
The Australian Taxation Office (ATO) is ending that era. While the initial anxiety surrounding a November 2026 deadline has been tempered by a recent extension, the writing is on the wall. After June 30, 2027, the ATO will stop accepting direct credit card payments for tax obligations.
For legal firms, medical practices, and professional service providers, this is not just an administrative shift. It’s a fundamental change to the operating rhythm of a business. Complacency is the enemy here. While June 30, 2027, may seem distant, the time required to adjust cash flow management, update accounting software integrations, and refine financial workflows is substantial.
Why the change?
The decision to phase out direct credit card payments is grounded in a broader government mandate to modernise digital services and reduce the overhead costs associated with processing merchant fees. Processing credit card transactions is significantly more expensive for the government than processing bank transfers or BPAY transactions. By moving taxpayers toward more efficient channels, the ATO aims to lower these transactional costs and streamline the payment reconciliation process.
However, for the business owner, the policy shift highlights an uncomfortable reality: tax liabilities must be treated with the same urgency as payroll or supplier invoices. Reliance on a credit card to float cash flow, even for a short duration, will no longer be a viable strategy when engaging with the ATO directly.
The impact on cash flow management
The most significant impact of this transition will be felt in the area of working capital management. Businesses that have traditionally used credit cards to manage the timing difference between receiving client payments and paying the ATO will need to re-evaluate their liquidity.
If a business relies on the interest-free period of a credit card to smooth out fluctuations in cash flow, the loss of this option necessitates a shift in how they budget for tax obligations.
This may require:
- Revisiting the timing of invoicing and debt collection to ensure funds are available when tax liabilities fall due.
- Assessing if the business has sufficient cash reserves to meet tax obligations without relying on credit.
- Considering whether to shorten the payment terms offered to clients to ensure cash is in the bank sooner.
For professionals who have relied on credit card reward points to subsidise business expenses, the change will also mean a decrease in these secondary benefits, unless they transition to third-party payment services that still facilitate credit card payments to the ATO (though these services often come with their own transaction fees).
A cost comparison of credit card vs other payment options
For years, paying the ATO by credit card has been an easy way to get up to 55 interest-free days. After 30 June 2027, that option ends, and covering the gap will come with a cost you can actually see.
Take a South Yarra medical practice with a $45,000 quarterly BAS that it needs to fund for 90 days.
Assuming a 25% company tax rate, here are the indicative after-tax costs:
- Tax holding account: a gain of about $333 in interest at 4%
- Third-party card service: about $506 to $675 in surcharges, provided the card is cleared on time
- Line of credit: about $749 at 9%
- Business overdraft: about $916 at 11%
- Tax funding loan: about $1,186, including fees
- ATO payment plan: about $1,238, because the general interest charge hasn’t been deductible since 1 July 2025
Over four BAS cycles, the difference between the cheapest and dearest options can reach $5,000 to $6,000 a year.
These figures are indicative only, as rates change regularly. Most practices do best with a tax holding account backed by a line of credit for shortfalls. Our cash flow modelling service and tax experts can run these scenarios with your own figures well before the deadline.
A small business checklist for compliance and preparedness
The transition away from credit cards is a forcing function for better financial discipline. Preparing now allows a business to integrate these changes into their standard operations without the panic of a last-minute deadline.
1. Audit current payment workflows
Identify every point in your current financial system where a credit card is used to pay the ATO. This includes:
- Direct manual payments on the ATO portal.
- Automated payments or recurring payment plans currently linked to a credit card.
- Accounting software integrations that automatically process tax payments via credit card.
2. Establish direct debit and BPAY procedures
Transition to payment methods that remain fully supported and cost-effective.
- BPAY: Ensure your accounting software is set up to handle BPAY payments for ATO liabilities.
- Direct Debit/EFT: Review your business bank accounts to ensure you have clear procedures for initiating timely Electronic Funds Transfers (EFT). The ATO provides specific EFT details, and it is critical to use the correct payment reference number (PRN) to ensure funds are allocated to the right account.
3. Review and update payment plans
If your business is currently on a payment plan with the ATO that is funded by a credit card, you must update this before the June 30, 2027, deadline. The ATO will require these plans to be transitioned to direct debit from a bank account. Failing to update these details may lead to the cancellation of your payment plan, which could trigger further enforcement action.
4. Evaluate third-party payment services
Some third-party providers allow businesses to pay their tax bills using a credit card, where the service provider then pays the ATO on the business’s behalf via EFT. If your business model fundamentally requires credit card usage, investigate these services.
However, approach this with a critical eye. These services charge transaction fees, which can erode any benefits gained from using a credit card. Calculate the true cost of using these services versus the cost of improving internal cash flow management.
5. Communicate with your small business accountant
Don’t manage this transition in a silo. Make an appointment with your accountant or tax specialist to discuss how your business is specifically impacted. They can help:
- Forecast cash flow to account for the loss of credit card timing buffers.
- Structure your BAS and other tax obligations more effectively.
- Ensure that any automated processes within your accounting software are correctly reconfigured to use EFT or BPAY.
Moving toward financial resilience with small business accounting and tax specialists
The shift away from credit card payments to the ATO is not just an administrative hurdle. It is an opportunity to move away from reliance on short-term debt for essential operational obligations. Businesses that can successfully pivot their financial operations to accommodate this change will emerge more robust and disciplined.
The goal is to move from a “just-in-time” cash management style, where credit cards provide the necessary cushion, to a more proactive model where tax obligations are anticipated and prepared for well in advance of their due dates. By auditing your current systems today, establishing reliable direct payment methods, and engaging professional guidance, you can ensure that this change becomes a routine update rather than a significant disruption to your business practice.
When the clock strikes midnight on June 30, 2027, the change in policy will take effect. The businesses that prepare now will not even notice the difference. The businesses that wait may face unnecessary administrative complications and, more importantly, unexpected pressure on their cash flow.

FAQs
Can I still pay the ATO with a credit card before 30 June 2027?
Yes. On 9 October 2026, the ATO confirmed that it will keep accepting credit card payments until 30 June 2027. It had originally planned to stop from 30 November 2026. The extra time is useful, but a business with quarterly BAS and PAYG instalments has only a few payment cycles left to test new arrangements. Need tax expertise in South Yarra, Northcote, or Fitzroy? We can help you plan the switch now so you’re not rushing next June.
Will debit cards, BPAY and bank transfers still be accepted by the ATO?
Yes. The change only affects credit cards. Under the ATO’s guidance, you’ll still be able to pay by BPAY, by bank transfer (EFT) using your payment reference number (PRN), and by direct debit. Debit cards are also expected to stay available but check the ATO’s “How to pay” page before you rely on one. If you’d like help choosing the method that suits your accounting software, contact our affordable small business accounting firm today.
What happens if my credit card payment plan isn’t updated in time?
The ATO has said it won’t accept credit card payments after 30 June 2027. That means instalments still linked to a card may fail. Missed instalments can put the payment plan at risk and lead to more interest. Update the plan to a bank account well before the deadline. We help Melbourne small businesses and practices in Richmond, Williamstown, Thornbury and beyond review their taxes, accounting software, compliance and more.
How do the new Dynamic PAYG instalments fit into this?
The ATO has proposed Dynamic PAYG instalments from July 2027. They’re meant to match your instalments more closely to how your business is actually performing. Because they’d start around the same time the credit card cut-off takes effect, they could make it easier to pay from your bank account. The design was still being finalised when we last checked in October 2026. Our Melbourne small business accounting and tax team keeps track of these changes and can tell you whether the new option would suit your business.
