If you run a small business registered for GST, two questions matter at the start of every financial year: how often you have to report and pay GST, and whether you can move to a different rhythm. The answer to the first is set by your circumstances, not your preference. The answer to the second depends on what has changed. This guide walks through the cycles the ATO describes, how to confirm which one applies to you, and what to do if you think you are eligible to change it.
The cycles the ATO describes
According to the ATO's "When and how to report and pay GST" guidance, your GST reporting cycle may be monthly, quarterly or annually, depending on your GST turnover and other requirements. The ATO frames this as a cycle you report and pay on — the two are linked, so changing one generally changes the other.
The one threshold stated in the ATO material is for monthly reporting: you must report and pay GST online each month if your business has a GST turnover of $20 million or more. Below that figure, the ATO's guidance points to quarterly and annual options, with eligibility depending on your turnover and other requirements that are set out on that page.
What this means practically: monthly reporting is the most demanding cycle in terms of how often you touch your books, and it is compulsory at the $20 million turnover level. Quarterly is the cycle most small businesses will encounter. Annual reporting exists as a further option in the ATO's framework, but whether it is available to you is a question to confirm against your own turnover figures rather than assume.
How to check which cycle you are on
Do not infer your cycle from what you did last year. Confirm it directly, because the ATO's records are what drive your activity statement obligations.
- Sign in to the ATO's online services for business and look at your account details. The ATO's GST page directs businesses to "access secure services, view your details and lodge online" — your current reporting cycle is held against your registration.
- Check your most recent activity statement. Any BAS or annual GST return already issued to you reflects the cycle the ATO currently has recorded for your business.
- Recalculate your GST turnover. If turnover has moved materially — up or down — that is the trigger the ATO identifies for a change in cycle. Work from your own records rather than estimates.
- Ask your registered tax agent to confirm the cycle on file if you lodge through one. Your agent sees the same ATO record and can tell you what has been applied.
If the cycle on file does not match what you expected, that is the moment to query it. The ATO's guidance notes that changes may happen when your GST turnover changes, which cuts both ways: growth can move you to a more frequent cycle, and a fall in turnover can open up a less frequent one.
When a change may be possible
The ATO states that depending on your circumstances, you can change the cycle you use to report and pay GST. It gives two situations where this may arise: when your GST turnover changes, or if you choose to report and pay using a different cycle.
Read those two carefully, because they are different in kind:
- A turnover-driven change follows from your business getting bigger or smaller. This is a factual question about your figures, and the ATO's page is the place to check what turnover level corresponds to which cycle.
- A choice-driven change is where you prefer a different cycle even though your circumstances have not forced one. Whether this is available to you depends on the ATO's requirements, which is why the guidance asks you to check rather than simply elect.
Eligibility is not universal. Some businesses will be required to stay on the cycle the ATO has assigned. Treat "can I change?" as a question to put to the ATO or your agent, not as an entitlement.
How to request a change
The ATO's GST page is the starting point for "if you need to change your GST reporting and payment cycle," and its secure online services are where changes are actioned. A sensible sequence:
- Confirm your current cycle and the date your next statement is due.
- Work out your current GST turnover from your records, so any request is supported by figures.
- Check the ATO's requirements for the cycle you want to move to, on the "When and how to report and pay GST" page.
- Make the change through ATO online services, or ask your registered tax agent to do it for you.
- Confirm the change has been applied before your next statement is due — check that the next issued activity statement matches the new cycle.
- Update your own systems: bookkeeping software, cash flow forecasts and internal deadlines all need to reflect the new rhythm.
Changing cycle mid-year can create a short or long reporting period at the transition point, so confirm with the ATO how the switchover will be handled rather than assuming your statements will simply continue on the same dates.
Cycle versus reporting method: don't confuse them
These are separate decisions, and mixing them up leads to the wrong request.
- Reporting cycle — how often you report and pay: monthly, quarterly or annually.
- Reporting method — how you work out the amounts. The Small Business Tax Super and You GST guidance (last modified 21 Jan 2026) lists the methods under "GST reporting methods": Simpler BAS, the full reporting method, and the GST instalment method.
You can change one without changing the other. A business might stay quarterly but move between methods as its record-keeping or cash flow needs shift. The same source also points to record-keeping responsibilities, GST-free items and services, and completing your BAS as related areas worth reviewing at the same time — if your records are not in order, changing frequency will simply surface the problem more often.
What to weigh before changing
| If you are considering | Weigh this |
|---|---|
| Moving to a more frequent cycle | More lodgements, tighter deadlines, but smaller amounts per payment and a closer link between trading activity and tax. |
| Moving to a less frequent cycle | Fewer lodgements, but larger amounts at once and a longer gap between earning and paying — budget for it. |
| Either direction | Whether your bookkeeping can keep up with the cycle's pace, and whether your cash flow absorbs the payment pattern. |
| Leaving it alone | Staying put is often reasonable if nothing has materially changed; a change is not automatically better. |
The honest test is administrative: does the cycle match how quickly you can close your books and how steadily cash moves through the business? If your records are always two weeks behind, a monthly cycle will be painful. If you hold large GST amounts for long periods, a longer cycle may strain cash flow when payment falls due.
Next steps
- Confirm your current GST reporting cycle through ATO online services or your tax agent.
- Calculate your current GST turnover from your own records.
- Read the ATO's "When and how to report and pay GST" page for the requirements attached to the cycle you want.
- If you are eligible and want to change, action it through ATO online services or your agent, then verify the change appears before your next statement is due.
- Re-check at the start of each financial year, or whenever turnover moves materially.
Specific due dates, turnover thresholds other than the $20 million monthly reporting threshold, and any conditions attached to quarterly or annual reporting are not set out here — verify them on the ATO page and the Small Business Tax Super and You GST guidance, or with a registered tax agent, before acting.
