The ATO is encouraging small businesses to reset their compliance habits for 2026, warning that avoidable mistakes contribute to a $27.2 billion income tax gap.
What’s happening: The Australian Taxation Office is encouraging small businesses to start 2026 with stronger compliance habits as it accelerates efforts to collect more than $50 billion in unpaid tax.
Why this matters: ATO Assistant Commissioner Angela Allen says avoidable mistakes contribute to the $27.2 billion small business income tax gap, urging owners to seek professional advice and implement practical cash flow management systems.
The Australian Taxation Office is urging small businesses to reset their compliance habits as the new year begins, warning that failure to address tax obligations now could result in firmer recovery actions later.
ATO Assistant Commissioner Angela Allen said the calendar year provides an opportunity for businesses to establish practices that will prevent problems throughout 2026 and beyond.
Small business owners face multiple pressure points, from keeping accurate records to managing cash flow effectively. Part of the $27.2 billion small business income tax gap stems from mistakes rather than deliberate evasion, making professional guidance particularly valuable for navigating complexity.
Allen emphasised that taking small practical steps immediately can make a substantial difference, whether setting funds aside to cover GST and PAYG withholding, staying current with ATO debts, or establishing calendar reminders for lodgement deadlines.
The tax office is pursuing more than $50 billion in unpaid obligations, with small business debts continuing to expand despite resumed collection activities. Business owners who cannot pay obligations in full or on time are urged to engage with the ATO or registered tax practitioners early rather than avoiding contact.
The ATO has stated explicitly that it operates as neither a bank nor a cheap financing source. Deliberately delaying tax payments to fund business operations creates an unfair competitive advantage over businesses meeting obligations punctually.
Cash flow management remains among the most significant challenges for small businesses, with many owners discovering at business activity statement time that funds for GST or PAYG withholding have not been preserved separately.
Allen recommended maintaining separate bank accounts for tax obligations, making it simpler to meet commitments and avoid unexpected shortfalls. Business owners are cautioned against using GST collected from customers or PAYG withholding collected from employees as working capital, despite the temptation to address short-term cash flow constraints.
Using these amounts to fund operations may provide temporary relief but creates substantially larger problems when obligations become due, making recovery more difficult.
The tax office continues observing instances where income is omitted from returns, particularly from businesses accepting cash payments or maintaining inconsistent record keeping practices. Accurate, consistent and complete record keeping constitutes a legal requirement beyond being sound business practice.
Businesses still using physical storage methods for records should transition to digital systems. Sole traders can utilise the ATO app, which offers features including myDeductions, a tax withheld calculator and the business performance check tool.
Small businesses should leverage the ATO’s online services to monitor lodgement status and track outstanding debts. The tax office maintains quarterly updated compliance focus areas on its website, providing transparency about risks under scrutiny.
Payday Super will require businesses to pay employees their superannuation guarantee with each pay period from July 2026. The ATO is urging small businesses to begin preparation now by reviewing payroll systems and superannuation processes to accommodate more frequent payments.
Allen stressed the importance of working with registered tax practitioners for businesses needing support with ATO obligations, recommending verification through the Tax Practitioners Board. Obtaining tax advice from informal sources including friends or social media platforms is inadvisable.
For business owners who have closed operations or are considering winding down in 2026, the ATO provides detailed guidance on required steps including cancelling ABNs, lodging final tax returns and business activity statements, and fulfilling payroll and superannuation obligations conclusively.
Allen noted that closing a business properly helps avoid future compliance complications, ensuring a clean exit from tax obligations.
The tax office has indicated it will take firmer action where deliberate non-compliance occurs, including shadow economy behaviours. Approximately 69 per cent of small business tax is paid on time with minimal ATO intervention, but a growing number of businesses with capacity to pay are waiting for pursuit before settling obligations or entering payment plans rather than paying in full.
Small businesses owing money to the ATO face multiple potential enforcement measures. The tax office can issue garnishee notices to third parties holding funds, apply director penalty notices for company directors, offset tax credits against debts, refer matters to external debt collection agencies, and take legal action including statutory demands that could lead to winding up proceedings.
The general interest charge currently applies at 11.38 per cent annually on unpaid tax debts, accumulating daily on outstanding balances. Payment plans can be arranged to break obligations into manageable instalments, though interest continues accruing during repayment periods.
Analysis suggests approximately half of unpaid debt is owed by businesses showing financial resilience, indicating capacity to pay exists in many cases. The ATO employs data analysis to distinguish between businesses capable but unwilling to pay and those genuinely lacking capacity.
For businesses experiencing genuine difficulty, early engagement with the ATO or trusted advisers provides the best opportunity to secure manageable arrangements and potentially mitigate penalties. Waiting until enforcement action is underway significantly limits available options.
The tax office maintains that ensuring everyone pays their fair share meets community expectations, with its role as Australia’s principal tax collector carrying legal obligations that cannot be ignored. For businesses facing financial pressures, transparent communication proves crucial.
The ATO encourages small businesses to use its support options and resources including the record keeping evaluation tool, the Cash Flow Kit, the Payday Super checklist and the online learning platform Essentials to strengthen your small business.
