How it worksHow the BAS calculator and reminder service runs a quarter.
Every BAS, you get two tailored emails: a prep reminder about two weeks before your due date, and a final nudge the week it is due. Both are matched to your reporting cycle and to whether you run payroll, and both open your BAS workspace with one click, where the period's figures are entered, remembered and totalled. The due dates never move, so the service is built around the only thing that does: remembering them, and arriving with the numbers ready. A quarter looks like this.
…then the loop restarts by itself: next period, the workspace already knows what last time looked like.
- Two weeks out. The prep email lands: your exact due date, your checklist (wages included if you run payroll), and one button into your workspace.
- You enter the period as it suits you: line by line in the BAS workspace: sales, expenses with GST per row, W1/W2 straight from payroll. It saves as you type and shows the payment-or-refund position live.
- Week-of. The second nudge arrives. If the workspace is done, you're lodging in minutes; if not, today's the day.
- After lodgement: email yourself the summary as a record, and the workspace remembers the period. Next quarter opens with "last time you paid $X" already on screen.
Ready for the next due date? Set it up in about a minute and the first reminder lands two weeks before your next BAS.
Start my remindersWhen BAS is dueBAS due dates for quarterly and monthly reporters, and the extra time a BAS agent gets.
A quarterly BAS is due on the 28th of the month after the quarter ends: 28 October, 28 February, 28 April and 28 July. A monthly BAS is due on the 21st of the following month. The December quarter already carries a built-in extra month, which is why it falls in February rather than January. If a due date lands on a weekend or public holiday, you have until the next business day. Lodging electronically through a registered BAS agent adds four weeks to three of the four quarters. Your reminders follow the standard dates, so you keep that buffer either way.
| Period | Standard due date | Through a BAS agent, lodged electronically |
|---|---|---|
| Quarter 1: July to September | 28 October | 25 November Reminded |
| Quarter 2: October to December | 28 February | 28 February, the extension is already built in Reminded |
| Quarter 3: January to March | 28 April | 26 May Reminded |
| Quarter 4: April to June | 28 July | 25 August Reminded |
| Monthly BAS | 21st of the following month | Same date; only the December monthly BAS moves, to 21 February Reminded |
| Annual GST return, voluntary registrants under $75,000 | 31 October, or 28 February if you do not lodge a tax return | Agent dates may differ Not covered |
Warning: Weekend and public holiday dates roll to the next business day. Your reminder names the actual day you have, not the printed date, and says when it has shifted.
Know your cycle? It is on your GST registration confirmation, and the form only needs that and your email.
Set up remindersWhat you getWhat every BAS reminder email includes, top to bottom.
Each reminder carries your own due date, a prep checklist built for your setup, and one button into your BAS workspace, with the second email arriving the week the BAS is due. Nothing in it is generic. A quarterly reporter with no staff gets a shorter list than a monthly reporter running payroll, and the December email reads differently from the June one because the quarters are different. Here is what is in it, in the order you read it.
- Your due date, not a generic one. Quarterly (28 October, 28 February, 28 April, 28 July) or monthly (the 21st), whichever cycle you are on, with weekend roll-overs noted so the day on screen is the day you actually have.
- A prep checklist tailored to you. Reconcile the period, gather tax invoices over $82.50, pull platform summaries, and if you are registered for PAYG withholding, the wages and withholding totals for W1 and W2 are on the list too.
- One click into your BAS workspace. Every reminder opens your workspace, where sales, expenses and wages go in line by line, your BAS position comes out, and your last periods are remembered across devices.
- Season smarts. The December quarter's built-in extension, the June quarter's collision with tax time, public holiday shifts. The email knows which BAS it is reminding you about and says so.
- The week-of follow-up. The second nudge is the one that actually prevents late lodgement. If the workspace is done, you are lodging in minutes; if not, today is the day.
Run payroll? Tick one box and W1 and W2 join your checklist, every period.
Get BAS remindersYour optionsA calendar entry, a BAS agent, or a BAS calculator with reminders: what each one covers.
Four dates in a phone calendar is where most people start. The question is what you want to be holding when the reminder goes off.
A calendar reminder.
Free, and it tells you a date and nothing else. It does not know whether you report quarterly or monthly, that the December quarter already has its extension built in, or that this month's 21st is a Saturday. It cannot list what to gather, and when it fires you still have to find last quarter's figures. For a business with a bookkeeper and tidy software, a calendar may be all you need. For a sole trader doing their own BAS, it is usually the reminder that gets swiped away.
A registered BAS agent lodging for you.
The most protection, at the agent's own fee. An agent lodging electronically gets four extra weeks on three of the four quarters, and if you give them everything in time, the ATO's safe harbour means a late lodgement is not your penalty. They also carry the figures. We are Registered BAS Agent 25972850, and this service is deliberately not that: it is a calculation and reminder tool for people who lodge themselves. If you would rather hand the whole BAS over, ask your own agent or bookkeeper, and use the reminders to make sure they have your records in time.
This service.
Two tailored emails per BAS and a workspace that does the arithmetic, for $9 + GST a month. You still lodge, through ATO online services or your agent, but you arrive with the due date, a checklist that matches your setup, and your figures already totalled from the period's bank statement. Nothing is locked in: cancel from the manage link in any email and no further charge is taken. It suits a sole trader, freelancer, tradie or rideshare driver who wants the BAS done without a bookkeeper's bill, and who would rather spend BAS week confirming figures than finding them.
Lodging yourself? Then this is the one built for you. Set it up and the next reminder does the remembering.
Start my remindersYour workspaceThe BAS workspace: a BAS calculator with memory, and a bank statement upload that is included.
Every reminder opens your personal BAS workspace: a line-by-line ledger for the period's money in and money out, with GST worked out per row and the whole BAS position, 1A, 1B, W2 and the bottom line, computed as you type. GST-free lines toggle off. Wages and withholding go in straight from your payroll records. It saves automatically, remembers past periods across devices through the link in your emails, and compares this period against the last so surprises announce themselves early. Subscribers also get the bank statement upload: drop in the period's files and every payment is grouped by who it was with, you mark each one business or not, nothing is assumed, and the figures add themselves up from your own calls.
Want the upload and the memory? Both come with the subscription, and the first reminder email carries your workspace link.
Get the full workspaceBefore you uploadBanking habits that make a BAS, and the bank statement upload, easy.
One business bank account, with every business dollar in and out of it, is the single habit that makes BAS time short. The upload sorts whatever you give it, and so does a bookkeeper or your agent, but a mixed statement means separating personal spending from business spending line by line before anyone can start on the GST. Six habits, in the order to set them up, and the first two do most of the work.
| Habit | Why it pays at BAS time |
|---|---|
| Run a dedicated business bank account | Every dollar in and out of one account makes coding (by you, your agent, or the upload) near-automatic. Start here |
| Keep personal spending out of it | Pay yourself with a regular transfer to your personal account, then spend from there. Mixed statements are the number one cause of slow, expensive bookkeeping. Start here |
| Put business costs on the business card | Even small ones. A cost that never touches the account is a GST credit that is easy to forget. Habit |
| Set aside the GST as you go | A standing transfer of roughly one-eleventh of takings into a saver account means the BAS payment is already sitting there when the due date arrives. Habit |
| Snap receipts when they happen | Tax invoices over $82.50 are what make credits claimable, and you have four years to claim them. A photos folder beats a shoebox. Habit |
| Reconcile monthly, not quarterly | Twenty minutes a month turns BAS week into a formality, and the week-of nudge becomes a confirmation rather than a scramble. Habit |
Statements already tidy? Then the upload takes minutes. Start the reminders and the workspace link arrives with the first email.
Start my remindersWhat it costsWhat the BAS calculator and reminder service costs, and what a late BAS costs instead.
$9 + GST a month, which is $9.90 including GST, charged monthly by card through Stripe, and you can cancel anytime from the manage link in any email. There is no lock-in, no cancellation fee and no further charge after you cancel. Set that against the other number: the ATO's failure to lodge penalty for a small business is one penalty unit, currently $364, for every 28 days or part of one that a BAS is late, up to five units or $1,820. One 28-day slip costs about three years of the service; the maximum penalty costs about fifteen.
Warning: A late BAS costs $364 per 28 days, up to $1,820, and that is before interest on anything unpaid. The penalty counts from the due date, and a single day late starts the first 28-day block.
$9 + GST, nothing locked in. Start now and the first reminder lands two weeks before your next due date.
Start my remindersQuestionsOther questions.
When do the reminders arrive?
Twice per BAS: a prep reminder about two weeks before your due date, and a final nudge the week it is due. The dates follow your cycle: quarterly (28 October, 28 February, 28 April, 28 July) or monthly (the 21st of the following month). When a date falls on a weekend or public holiday, the reminder names the next business day, which is the day the ATO gives you.
What's actually in the reminder email?
Your specific due date, a prep checklist tailored to your setup (including PAYG wages and withholding for W1 and W2 if you have employees), one button into your BAS workspace to run your numbers, and season-specific notes such as the December quarter's built-in extension or the June quarter landing in tax time. The manage link for your subscription and the 1800 546 526 help line are in every email too.
Does the service lodge my BAS for me?
No. It is a reminder and preparation service, not a lodgement service. You (or your agent) still lodge, through ATO Online services for business or Online services for individuals and sole traders, which are free to use, or through a registered agent. It exists to make sure the due date never ambushes you and the numbers are ready when it arrives.
Is the BAS workspace part of the subscription?
The workspace itself is free for anyone to use on this site. Subscribers get the full version of it: the link in every reminder ties it to your subscription, so your periods are remembered across devices, past-period comparisons appear automatically, the bank statement upload is switched on, and the reminders and workspace work as one system.
How do I cancel?
Anytime, self-serve. Every email includes a manage link to your billing portal where you can cancel in two clicks. No lock-in, no cancellation fee, and no more charges after you cancel. If you would rather we did it, call 1800 546 526 during business hours.
What happens if I lodge my BAS late?
The ATO's failure to lodge on time penalty for a small business is one penalty unit for each 28 days, or part of one, that the BAS is overdue, up to five units. A penalty unit is $364 for infringements on or after 1 July 2026, so a late quarterly BAS costs $364 to $1,820, plus interest on any GST unpaid. The ATO can remit all or part of it depending on your circumstances, and expects the outstanding BAS lodged before you ask.
Do I get extra time if a BAS agent lodges for me?
Usually, yes. Under the ATO's BAS agent lodgment program for 2026-27, quarterly BAS lodged electronically by an agent are due 25 November, 26 May and 25 August instead of 28 October, 28 April and 28 July. The December quarter stays at 28 February because its extension is already built into the standard date. The concession applies when your previous statement was also lodged electronically. If you lodge yourself, the standard dates apply, and your reminders are built on those.
Doesn't the ATO already remind me?
Partly. The ATO emails most taxpayers who use its online services about 21 days before the due date to say the BAS is available, provided your email address is current. That tells you a BAS exists. It does not carry your checklist, your W1 and W2, your past periods, or a week-of follow-up, and it does not open a workspace with your figures in it. The two work well together.
Can I use the bank statement upload without subscribing?
The upload is included with the subscription and lives inside the BAS workspace, which the link in every reminder opens ready to go. Files are analysed in your browser and never reach our servers, so nothing is stored either way. If you only want a one-off figure, the free BAS calculator and GST calculator are open to everyone.
Do I need to be registered for GST to use this?
A BAS exists because you are registered for GST, PAYG withholding or another obligation that is reported on it, so most subscribers are GST-registered. If you are not yet registered and need to be, register for GST first; the form offers the reminders at the end so they start from your first due date. If you are unsure whether you need to register, do I need to register for GST? works through it.
