ATO pressure is rising: What accountants should watch in 2026

For a while there, the ATO gave everyone a bit of breathing room, with more flexibility around lodgements, payment plans, and debt management. But in 2026, that era is over.

For accountants, this is a signal that proactive advice is more important than ever. Spotting warning signs early and providing strategic cash flow guidance can make the difference between manageable debt and serious ATO action.

There are some signs of targeted relief. The government has recently flagged temporary measures for businesses under pressure, including more flexible payment plans and potential interest relief [4]. But these are designed as short-term support, not a return to pandemic-era leniency.

So what should accountants actually be watching this year? Here are the key developments shaping ATO compliance and tax debt in 2026.

DPNs are being used more aggressively

After years of pandemic-era leniency, the ATO is going back to ‘business as usual’ enforcement activity, focusing on recovering overdue tax and super liabilities. 

Director Penalty Notices (DPNs), specifically, mean that directors can be personally liable for certain company tax debts, like PAYG withholding, net GST, and SGC. They usually have 21 days to act – whether by paying the debt, choosing an administrator, or entering a restructure – before the ATO escalates its recovery measures.

While DPNs aren’t new, they’re now being issued earlier and more often [1].

Accountant takeaway: Keep a close eye on payroll, GST, and super. If these are slipping, it’s time to raise the red flag with clients.

ATO payment plans are becoming harder to rely on

Payment plans can be a real lifeline for business owners when cash flow gets tight — that’s what they’re there for. 

But they’re not a fail-safe anymore, and in 2026, the ATO is watching them more closely. Miss an instalment or fall behind, and enforcement action can ramp up quickly [2].

Accountant takeaway: Think of a plan as a temporary bridge, not a long-term solution. If your client’s cash flow is stretched, consider alternative financing or restructuring before the ATO does it for you.

Payday Super will expose cash flow issues faster

The biggest compliance shakeup in years is coming with payday super. From 1 July 2026, employers will be required to pay super at the same time they pay wages [3]. That’s a major shift from quarterly contributions and means employers will need major payroll and cash flow planning to manage contributions each pay run.

The ATO will closely monitor compliance through Single Touch Payroll and super data feeds, meaning late or missing super payments will be detected much earlier than under the old quarterly system.

Accountant takeaway: Now’s the time to help your clients audit their payroll. Getting ahead of the curve means payday super isn’t a source of unexpected pressure later in the year.

Carrying tax debt is becoming more expensive

Another big change that accountants must flag? Interest on overdue ATO debts – that’s GIC and SIC – is no longer tax‑deductible.

That means businesses carrying ATO debt face a purer, after‑tax cost, comparable to or higher than many commercial borrowing rates, with no deduction to soften the blow.

Because GIC compounds daily, the longer a tax debt remains unpaid, the more it can erode cash flow.

Accountant takeaway: Make sure clients understand the real cost of leaving tax debts outstanding. Paying or refinancing sooner rather than later often makes financial sense.

Why this matters for accountants in 2026

2026 is different. The ATO is prioritising early detection, timely payment and active enforcement. Using tools like DPNs and tighter scrutiny on plans means clients can find themselves in trouble sooner than they expect.

For accountants, this means a shift from compliance processing to strategic cash flow advising. Warning signals like late BAS, rising PAYG balances or stretched payment plans should trigger deeper conversations.

Protecting clients before ATO pressure hits

The key to navigating rising ATO pressure is being proactive. That can look like:

• Regular reviews of BAS, PAYG and super positions
• Cash flow modelling, including tax and super timing changes
• Strategic conversations about refinancing or alternative funding before debts accumulate
• Talking openly about risk with business owners so interventions never come as a surprise

When ATO debt starts building, timing matters. If a client needs help managing tax debt or cash flow in general, speaking with a finance specialist early can open up more options.
