Key dates and tasks for your Australian business
Select a month to view key tasks and deadlines. Note: Dates may shift to the next business day if they fall on a weekend or public holiday.
This tool provides general information on key financial year dates only and does not constitute advice. Dates may vary by state, business size, structure, or circumstance (e.g., monthly vs. quarterly lodgers, use of tax agent)—confirm with a professional or the ATO for your specific situation. Payroll tax dates vary by state/territory. Super payments must be received by the fund by the due date. Explore Scale Suite’s resources for additional insights.
Purpose:
Tailored for Australian SMEs, startups, and sole traders, this tool provides a month-by-month breakdown of critical financial year deadlines to ensure regulatory compliance. It covers ATO requirements like quarterly BAS due dates, superannuation guarantee payments (emphasising receipt by the fund), payroll tax (with state variations noted), and tax returns.
Ideal for planning without complex software - helps prevent missed deadlines that could incur fines up to $313 per day per obligation.
Step 1: Select a Month: Choose from the dropdown (July 2025 to June 2026) to focus on specific periods.
Step 2: View Tasks: Click the button to display a list of key dates, descriptions, and notes (e.g., "must be received by the super fund").
Step 3: Review and Plan: Read the tasks, note any that apply to your business, and confirm details with the ATO or advisor.
Tips for Ongoing Use:
Bookmark this page (Ctrl+D or Cmd+D) for quick reference during quarterly reviews. Use it alongside your calendar app by exporting notes or setting reminders for dates like 28 October 2025 (Q1 BAS). For businesses with varying obligations (e.g., monthly vs. quarterly lodgers), filter tasks based on your setup. Always check for updates, as dates may shift for weekends/holidays or state-specific rules. If managing multiple entities, pair with accounting tools like MYOB for automation. Non-GST registered? Focus on non-GST tasks like payroll.
Understanding ATO Compliance Requirements:
Per ATO guidelines (updated for 2025-26), businesses must meet deadlines for lodgements and payments to avoid penalties—e.g., super guarantee contributions at 12% must be received by the fund by 28th of the month following each quarter (or next business day). BAS/IAS due dates vary: monthly lodgers by the 21st, quarterly by the 28th (with extensions via tax agents). Payroll tax is state-based (often 7th monthly), and tax returns differ by entity: self-preparers by 31 October 2025, agents often to May 2026. FBT year ends 31 March 2026, with lodgement by 21 May. TPAR applies to specific industries by 28 August. This tool incorporates these standards Australia-wide, but variations exist by business size/structure - e.g., no extensions for large entities.
Non-compliance risks audits or fines; always verify via ATO's business portal. For complex needs, Scale Suite provides tailored compliance support to keep your operations smooth.
