BAS quarters, STP finalisation, Payday Super and your ASIC review date in one place. These are the published dates — the floor, before any agent program shifts them.

| You get | the next dates that apply to you — the published floor, before any agent lodgment program moves them. |
A worked example
The lookup below already shows your next standard quarterly BAS date — and the ASIC review field turns an incorporation date into this year’s review date.
The BAS dates below are the ATO’s published standard quarters and do not depend on any input — they are the same for every self-lodging business.
- Q1 · July – September
- 28 October
- Q2 · October – December
- 28 February
- Q3 · January – March
- 28 April
- Q4 · April – June
- 28 July
- Monthly BAS
- 21st of the following month (mandatory once GST turnover reaches $20 million; optional below)
Next standard quarterly BAS — Q1 (July – September)
- STP finalisation
- 14 July (Single Touch Payroll finalisation declaration for the financial year just ended)
- Next ASIC annual review
- Enter an incorporation date
From 1 July 2026, super must be RECEIVED by the employee’s fund within 7 business days of each payday (Payday Super). The old quarterly 28-day due dates apply only to periods before 1 July 2026.
An estimate, not a quote. The ATO and ASIC produces the figure that actually applies to you — check there before you rely on a number. A date falling on a weekend or public holiday moves to the next business day — public holidays vary by state, so this tool does not shift dates for you. Verified 2026-08-14.
Why your dates may legitimately differ
Registered agents lodge under the ATO’s lodgment program, which carries its own later dates for most quarters. Those are a concession, not a statutory deadline, and your agent’s program governs — confirm yours with them rather than working to the standard dates above.
What to do with this number: Standard dates are the floor, not your dates: a registered agent’s lodgment program can extend BAS deadlines, and the statement ASIC actually issues governs the review. Confirm yours with your agent.
