From 1 July 2025, Australian small and medium-sized businesses will face intensified scrutiny under the Australian Taxation Office’s (ATO) $1 billion compliance crackdown. While the initiative is designed to target tax evasion and level the playing field, even honest SMEs will come under the microscope.
ATO Deputy Commissioner Will Day says only a small portion – around 5% – of small businesses are deliberately avoiding tax. But that still leaves a significant $17.7 billion tax gap, largely driven by mistakes, opportunistic behaviour, and poor record-keeping.
With audits set to increase and data-matching tools becoming more advanced, even businesses doing the right thing may find themselves subject to greater scrutiny. That’s why now is the time to double-check your records, revisit your tax strategy, and act early if support is needed.
The majority of SMEs are already doing the right thing. Staying proactive will ensure they’re not caught off guard as the ATO’s new measures take effect.
Carrying ATO tax debt is getting more expensive
From 1 July, managing tax debt will become more costly for SMEs. “Small businesses’ tax debts continue to be too high,” said Day. The ATO reported $53 billion in collectable debt at the end of FY24 – $35.6 billion owed by small businesses.
New legislation removes tax deductions for ATO interest charges, including the General Interest Charge (GIC) and Shortfall Interest Charge (SIC). With GIC already exceeding 11% and compounding daily, the cost of carrying tax debt is rising sharply.
“Many businesses underestimate their tax liabilities, leading to significant debt,” says Olga Koskie, Principal at Tax Assure. She notes it’s crucial for business owners to take a proactive approach to managing their tax debts.
The ATO also wants to shed its image as a lender of last resort, which means SMEs relying on ATO payment plans should reassess their strategies, with tighter repayment terms coming into force from 1 July.
Alternative finance options may offer relief. “Working capital finance can help businesses repay debt and meet ongoing obligations – especially when revenue is lumpy,” says Campbell McCallum, Octet’s CFO. “Supplementary Trade Finance, for example, offers a revolving line of credit to pay suppliers, freeing up funds for tax.”
Tax minimisation schemes under the microscope
Many SMEs use legitimate tax strategies to manage cash flow – but under the ATO’s new compliance push, some of these approaches will face closer examination.
The ATO has flagged that strategies involving income diversion for personal use, inflated deductions, or artificial losses could fall into risky territory if not properly substantiated. “If you look at both the tax gap and the debt book, they are symptoms of a system operating less than optimally,” said the Deputy Commissioner.
Tax practitioners are also on the radar. The Tax Practitioners Board has received an additional $27.3 million in funding to investigate high-risk advisors who may be promoting overly aggressive schemes.
The ATO is clear that most businesses are doing their best to comply. But with greater scrutiny ahead, it’s a timely reminder to review any existing strategies, seek trusted advice, and ensure they align with the letter of the law.
Shadow economy in the crosshairs
The ATO is also cracking down on the “shadow economy” – cash-in-hand dealings and undeclared income. While only a handful of SMEs are believed to engage in deliberately dishonest behaviour, the ATO says the ripple effect on compliant businesses and public services is significant.
“Deliberate shadow economy behaviours contribute nearly 60% of the gross small business income tax gap – or around $11.2 billion,” Day explained. “Approximately $8.9 billion of this is associated with underreporting of income and over-claiming of deductions. The remainder is hidden wages and people operating completely outside the tax system.”
To fight back, the ATO is enhancing its anomaly detection tools – such as flagging unusually low sales for a sector – and sharing intelligence across agencies via the Shadow Economy Taskforce.
Industries most exposed to cash transactions – like construction, hospitality, cleaning, and ride-sharing – should expect closer scrutiny.
Prepare for a new era of tax enforcement
The 1 July changes mark more than the start of a new financial year – they signal a shift in how the ATO engages with small business compliance.
Audits will become more targeted, digital surveillance more sophisticated, and there will be less leniency for practices that push the boundaries of what’s acceptable. The ATO is also tightening expectations around debt management and placing greater responsibility on advisors to guide clients responsibly.
For compliant businesses, this isn’t cause for alarm, but taking steps now to review your tax position and stay informed can help you navigate the changes with confidence and avoid unnecessary disruption down the track.
