BAS & PAYG — quarterly
For businesses that report GST and PAYG quarterly. Monthly BAS lodgers lodge and pay by the 21st of the following month.
| Quarter | Period | Due date |
|---|---|---|
| Q1 | Jul – Sep 2026 | 28 October 2026 |
| Q2 | Oct – Dec 2026 | 28 February 2027 (extended over the holidays) |
| Q3 | Jan – Mar 2027 | 28 April 2027 |
| Q4 | Apr – Jun 2027 | 28 July 2027 |
Super — Payday Super (new from 1 July 2026)
The quarterly super due dates are gone. From 1 July 2026, Payday Super requires employers to pay super guarantee at the same time as wages — the contribution must reach the employee’s fund within 7 business days of each payday. The old 28 October / 28 January / 28 April / 28 July quarterly dates no longer apply. The ATO has a transitional compliance approach for this first year, but plan for super on every pay run.
Income tax returns — for the 2025–2026 year
For the income year that ended 30 June 2026.
| Who | Lodge yourself | Via registered tax agent |

| Individuals & most taxpayers | 31 October 2026 | Later — often into May 2027, if you’re on the agent’s books before 31 October |
Payroll — STP finalisation
| Obligation | Applies to | Due date |
|---|---|---|
| Single Touch Payroll finalisation declaration | 2025–2026 payroll year | 14 July 2026 |

The FBT year is offset from the financial year — it runs 1 April to 31 March.

| FBT year | 1 Apr 2026 – 31 Mar 2027 |
| FBT return & payment (self-lodge) | 21 May 2027 |

How to read these dates
- Weekends & public holidays: if a due date falls on a weekend or public holiday, you can lodge and pay the next business day.
- Tax-agent extensions: registered tax and BAS agents on the lodgement program get later dates than the self-lodger dates shown here.
- Your cycle may differ: large PAYG withholders, monthly BAS lodgers and some small businesses have different dates. Confirm your own obligations with the ATO or your agent.

Frequently asked questions
When is my BAS due?
Quarterly BAS lodgers have four due dates a year: Q1 (Jul–Sep) is due 28 October, Q2 (Oct–Dec) 28 February — the ATO gives an extra month over the holidays — Q3 (Jan–Mar) 28 April, and Q4 (Apr–Jun) 28 July. Monthly BAS lodgers lodge and pay by the 21st of the following month. If you lodge through a registered BAS or tax agent you generally get a few extra weeks on the quarterly dates (except Q2).
Do the old quarterly super due dates still apply?
No — from 1 July 2026, Payday Super applies. Employers must pay super guarantee at the same time as wages, with the contribution reaching the employee's fund within 7 business days of payday. The old quarterly SG due dates (28 October / 28 January / 28 April / 28 July) no longer apply. The ATO has published a transitional compliance approach for the first year, so check your risk position, but plan for super on every pay run.
When is my income tax return due?
If you lodge your own return, it's due 31 October for the income year that ended on 30 June. If you use a registered tax agent and are on their lodgement program, you usually get much longer — often into the following May — but you generally have to be on the agent's books before 31 October to get the extension.
What if a due date lands on a weekend or public holiday?
The ATO lets you lodge or pay on the next business day without penalty when a due date falls on a weekend or a national/most-state public holiday. The dates on this page are the standard statutory dates; shift to the next business day where one falls on a weekend.
Why is the FBT year different from the financial year?
Fringe benefits tax runs on its own year — 1 April to 31 March — which is offset three months from the 1 July–30 June financial year. If you provide fringe benefits (company cars, entertainment, etc.), the FBT return and payment are generally due 21 May, with later dates available through a tax agent.
Are these dates official?
They're the standard ATO due dates for the 2026–2027 financial year, drawn from the ATO's published lodgment and payment dates. Your own dates can differ — for example, large PAYG withholders report more often, tax-agent clients get extensions, and some small businesses have different cycles. Always confirm your specific obligations with the ATO or your registered agent.
