The 2026–27 cash crunch calendar: the dates that squeeze Australian businesses

Cash crunches rarely come out of nowhere. Most of them sit on the calendar months in advance: a BAS due the same week as a pay run, a holiday shutdown followed by slow-paying customers, a big quarter’s GST landing in a quiet month. The 2026–27 financial year also brings the first full year of Payday Super, which reshapes when money leaves the account. This guide maps the dates that matter and how to get ahead of each one.

Which dates matter most in 2026–27?

Here are the fixed dates most likely to pull large amounts out of a business account, based on ATO due dates. If you lodge through a registered tax agent, your lodgement dates may differ — check with them.

Date	What’s due	Notes
Every payday + 7 business days	Super guarantee received by funds	Payday Super, from 1 July 2026
21st of each month	Monthly BAS	Next business day if it falls on a weekend or public holiday
Wednesday 28 October 2026	Quarterly BAS (July–September)
Late December to mid-January	Holiday shutdown, slower receipts	Wages and leave still payable
Monday 1 March 2027	Quarterly BAS (October–December)	28 February 2027 is a Sunday
Wednesday 28 April 2027	Quarterly BAS (January–March)
Wednesday 30 June 2027	End of financial year	Assets must be first used or installed ready for use to count in 2026–27
Wednesday 28 July 2027	Quarterly BAS (April–June)

On top of these sit your own business’s fixed outflows: rent, insurance renewals, loan repayments, registrations and licences, and annual subscriptions. Add them to the same calendar.

How does Payday Super change the calendar?

Before 1 July 2026, many employers paid super quarterly — a large, predictable outflow four times a year, which often sat near BAS dates. Under Payday Super, the ATO says super guarantee contributions must be received by employees’ super funds within 7 business days after you pay your employees, with some exceptions such as for new employees. The super guarantee is still 12%.

What that means for your calendar:

• No more quarterly super lump — but a smaller outflow after every pay run.
• Pay runs become double events. Wages on payday, super within days. Plan both together.
• Crunch weeks shift. The danger is no longer one quarter-end week but any fortnight where receipts are slow.

A business that pays fortnightly now has 26 super deadlines a year instead of four. Our page on Payday Super shortfall covers what to do when one of them is at risk.

Why is late summer the hardest stretch?

For a lot of Australian businesses, the period from Christmas to early March is the tightest of the year:

1. December — trading may be strong for retail and hospitality, but many B2B businesses slow down. Staff take leave, which is still paid.
2. Shutdown weeks — little or no invoicing for many trades and professional services.
3. January — customers return slowly; payments for December invoices drift.
4. Late February to 1 March 2027 — the October–December quarter BAS is due, often based on a strong pre-Christmas quarter, just as receipts are at their lowest.

If your business follows this pattern, the December quarter BAS is the one to plan for from October. Set aside GST weekly through November and December, and if a gap still looks likely, arrange funding before the break rather than during it. See BAS bill due for options, or talk to us about a standby facility now while things are calm.

What about the end of the financial year?

30 June 2027 matters in two ways:

• Asset timing. The ATO says the $20,000 instant asset write-off is permanent from 1 July 2026 for small businesses with aggregated turnover under $10 million. The asset must be first used, or installed ready for use, in the income year you claim it. An asset delivered in late June but not installed until July falls into the next year. If a purchase is planned, fund and install it with time to spare — see equipment and vehicle funding.
• Year-end pressures. Annual insurances, stocktakes and bonus payments often cluster around June, followed by the April–June BAS on 28 July.

Talk to your accountant about how year-end timing affects your tax position; this guide is about the cash.

How do you build your own cash crunch calendar?

An afternoon’s work, using your accounting software and bank statements:

1. List every fixed date from the table above that applies to you.
2. Add your pay runs for the year and the super deadline 7 business days after each.
3. Add your big recurring bills — rent, insurance, registrations, loan repayments.
4. Estimate income by month using last year’s bank statements as a guide.
5. Mark the weeks where outflows bunch up and income dips. Those are your crunch weeks.
6. Decide how each crunch week will be covered: cash set aside, collections pushed earlier, supplier terms negotiated, or a funding facility.

The business.gov.au cash flow pages have a free cash flow statement template that makes step 4 easier.

When should you arrange funding for the crunch weeks?

Before you need it. The difference is significant:

	Arranged a month ahead	Arranged in the crunch week
Options available	Line of credit, longer terms, property-secured choices	Whatever can fund fastest
Time to compare offers	Days	Hours
Stress	Low	High
Cost	Usually lower	Often higher

A business line of credit is designed for exactly this pattern: set it up once, draw in crunch weeks, repay when receipts recover. Our guide on standby funding before you need it explains how to approach it.

What does a mapped year look like? An illustrative example

A Brisbane commercial cleaning company with 30 staff, paid fortnightly, maps its 2026–27 year:

• Fortnightly — wages of about $65,000 and super within 7 business days after each pay run.
• 28 October 2026 — September quarter BAS, typically $55,000.
• Late December — two-week reduced roster, but leave loading and wages still paid; several clients close for January.
• January 2027 — receipts drop about a third as clients pay December invoices late.
• 1 March 2027 — December quarter BAS, around $60,000, landing in the same week as a pay run.
• June 2027 — a planned $18,000 floor scrubber purchase, to be installed before 30 June.

The owner sees that late February to early March is the danger zone: a pay run, the super that follows it and the BAS all within about ten days, with January’s slow receipts still catching up. In October, she arranges a $100,000 line of credit. In the end she draws $45,000 in late February, repays it by April, and buys the scrubber in May from cash flow. Nothing about the year was unusual. It just stopped being a surprise.

What if your business doesn’t follow the usual pattern?

Not every business is squeezed in late summer. A ski-hire operator’s toughest months are the off-season; a tax agent is flat out before the October lodgement period and quieter afterwards; an agricultural supplier moves with harvest and planting. The method is the same: plot your own income by month from last year’s bank statements, lay the fixed dates over the top, and look for the weeks where outflows bunch up while income dips. Those weeks — whenever they fall — are the ones to plan funding for.

Take the surprise out of the year

Knowing your crunch weeks is half the job; having funding ready for them is the other half. Applying is free and doesn’t involve a credit check, your details are worked on by one team rather than shopped to a crowd of lenders, and a real person helps you set up the right buffer for your calendar.
