Lodging through a registered BAS or tax agent adds roughly four weeks to most quarterly BAS due dates. Not all of them, and not automatically for a business that engaged an agent last week. The December quarter gets no agent extension at all, and the concession only attaches once your agent has electronically lodged a statement for you.
That last point is the one that costs people. Here’s how the concession works in practice, and what to do about the quarter it doesn’t cover.
Does the extra four weeks actually belong to you?
No. It belongs to your agent.
The concession exists so a registered agent can work through a client list without every business on it hitting the same wall on the 28th. It was never designed as breathing room for the business owner, and treating it that way is how a comfortable deadline turns into a rushed one.
Hand over a folder of unsorted receipts on 24 November and you’ve gained nothing. You’ve compressed someone else’s turnaround and raised the odds of a coding error going through unnoticed. Everything that determines whether a BAS is correct happens before the lodgement, not at it.
The practical version: your internal deadline is still the 28th. The concession is the buffer that absorbs a late supplier statement or a pay run that needs unwinding, and it works precisely because it’s rarely called on.
Why the December quarter is the one that catches people out
The October quarter gets all the attention. December is where businesses actually come unstuck.
There’s no agent extension on that quarter, because the standard date already sits a month later than the usual pattern. On paper that looks generous. In practice it lands on the wrong side of a Christmas shutdown, a January where half your suppliers are unreachable and your own bookkeeping rhythm has quietly stopped, and a February that vanishes faster than any other month.
One detail worth putting in the calendar now: 28 February 2027 is a Sunday, so the operative date rolls to Monday 1 March 2027. Most default calendar entries still have the 28th.
Melbourne hospitality operators feel that quarter hardest. December trading pushes GST collected to its annual peak, January revenue drops away, and the liability from your busiest quarter falls due in your quietest one. Function venues and retailers sit in the same trap. The money for that statement needs to be quarantined in January, not hunted down in late February.
Do you get the concession if you engage an agent this month?
Usually not for the quarter you’re currently worried about.
The lodgement program applies to statements generated after your agent has lodged your previous activity statement electronically. If it’s your first statement with a new agent, or the last one went in on paper, the earlier date can still apply. Ringing a bookkeeper on 27 October does not retroactively buy you a month.
Which makes July the sensible time to sort this out, not October. The changeover work is identical either way: reviewing recent lodgements against the GST detail report and the STP totals coming out of payroll, confirming the reporting cycle and GST method match what the ATO has on file, and getting the agent’s authority in place. Done in a quiet week, that’s routine admin. Done in the fortnight before a deadline, it produces a rushed statement and no concession anyway.
Worth confirming your agent’s registration on the Tax Practitioners Board register while the paperwork is open. Only a registered BAS or tax agent can lodge under the program, and the Tax Agent Services Act 2009 defines what a BAS service covers.
Which quarters carry a concession, and by how much
Three of the four. The September, March and June quarters each move out by about four weeks. The December quarter doesn’t move, because 28 February is already the deferred date, applied to everyone rather than to agent clients specifically.
Monthly lodgers sit outside the program almost entirely. The 21st holds regardless of who lodges, with one narrow exception for the December statement, which defers into February and then falls due on the same day as the January statement. Two months of GST and PAYG landing on one date is worth seeing coming.

FAQs
Do I need to apply for the BAS agent concession?
No. It attaches automatically to eligible quarterly statements lodged electronically by your registered agent. There’s no form, no approval, and no fee. What breaks it is a paper lodgement or a first statement under a new arrangement.
I'm engaging a bookkeeper this month. Will my next BAS get the extension?
Possibly not. The concession applies to statements generated after your agent has electronically lodged one for you, so the first quarter often runs on the standard date. Ask the question during onboarding and plan that first lodgement to the 28th.
Is the agent concession better than lodging online myself?
On time alone, yes. Self-lodgers who submit quarterly BAS online through Online services for business, myGov or SBR-enabled software generally pick up an extra two weeks. An agent lodgement adds roughly four. Neither helps with the December quarter.
Does the concession apply to monthly BAS?
No. Monthly statements are due on the 21st of the following month, whoever lodges them. The one exception is the December monthly statement, where an eligible business under the turnover threshold can have an agent lodge it electronically for a deferral into February.
Lodging through a registered BAS or tax agent adds roughly four weeks to most quarterly BAS due dates. Not all of them, and not automatically for a business that engaged an agent last week. The December quarter gets no agent extension at all, and the concession only attaches once your agent has electronically lodged a statement for you.
