Spotlight on Australia’s New Compliance Environment
Australia has introduced and implemented various reforms affecting multinational groups and small businesses alike:
-
Pillar Two Minimum Tax Regulations: Australia has legislated the OECD’s global and domestic minimum tax rules, in force for fiscal years starting 1 January 2024 (DMT/IIR) and 1 January 2025 (UTPR). Returns for in-scope MNE groups are due by 30 June 2026. (taxnews.ey.com)
-
Small Business Compliance Areas of Focus: The ATO’s “Getting It Right” campaigns highlight areas such as contractors omitting income, non-commercial loss claims, misunderstanding GST obligations (especially in ride-sourcing and taxi sectors), and misuse of small business CGT concessions.

Risk Points and How to Mitigate Them
| Issue | Why It’s Risky | What You Should Do |
|---|---|---|
| Omitted income from side hustles or gig economy work | Data matching and net-flow data identifying undeclared income can trigger audits or penalties | Keep invoices, bank records; declare all income—even from seemingly small or informal jobs |
| Granting incorrect deductions (non-commercial losses, ATO interest, etc.) | High chance of being denied if you do not meet specific tests or standards | Check eligibility; don’t claim losses that trade at a loss without profit motive; avoid claiming interest on ATO charges where no deduction is allowed from 1 July 2025. (ato.gov.au) |
| GST registration and reporting errors | Late registration or misreporting leads to penalties; roll timing (quarterly vs monthly) influences cashflow | Monitor turnover; register when required; organize bookkeeping; consider monthly BAS if flagged by ATO; plan for cashflow to meet liabilities |
| Pillar Two mis-filings or missed deadlines | Missing obligations or incorrect calculations on IIR, UTPR, DMT returns can result in penalties and retrospective liabilities | Identify whether your MNE group is in scope; engage advisors; start internal systems for data gathering; consider safe-harbor and exemption elections early |
Practical Action Checklist
- Conduct a compliance health check: Review your recent tax returns, GST status, PAYG obligations, and whether you have ever claimed non-commercial losses.
- Document everything: As emphasis increases, the necessity of evidence (invoices, contracts, valuations) is non-negotiable.
- Review structure and eligibility for incentives: Ensure your business structure still makes sense under new rules (CGT concessions, incentives). If not, consider restructuring lawfully.
- Plan for deadlines: For Pillar Two, 30 June 2026 looms large for first returns. For small business, new instant write-off windows and extended amendment periods influence timing. (taxnews.ey.com)
- Seek professional support: Especially for cross-border issues or MNE groups, expert advice can save time, errors, and money.
Example Case Study
Jenny runs a small ride-share business, turns over ~$90,000/year, and also freelances in UX design.
- She must register for GST due to ride sharing income. She didn’t previously include rideshare revenue in her freelancing base; now that income is visible via platforms and bank inflows, the ATO is likely to match it.
- If using a sole trader structure, she’s fully liable for ATO interest charges, which from 1 July 2025 are not deductible. ( She should budget accordingly. (ato.gov.au) )
- She can take advantage of the instant asset write-off for small business for eligible assets (if turnover < $10 million) costing < $20,000. (ato.gov.au)
- If she ever grows into part of an international group, Pillar Two becomes relevant; documentation and structure made now will reduce future compliance friction.
Staying compliant in 2026 means staying informed. For businesses large or small, there’s no substitute for structured record-keeping, early action, and leveraging expert advice when needed.
