I’ll be honest: deadlines can still make me feel like I’ve forgotten something.

Even after years of working with Australian businesses, there are moments when I look at a calendar, see several ATO and payroll obligations clustered together, and think, Have I missed a date? Is there another change I need to know about?

That feeling is completely normal.

But here’s the thing: financial confidence doesn’t come from memorising every rule. It comes from having a clear process, checking the right information early, and knowing what your numbers are trying to tell you.

This August, there are a few money moments worth putting firmly on your calendar. Payday Super is now in effect. The July monthly activity statement is due on 21 August. Then, on 28 August, some businesses face the Taxable Payments Annual Report (TPAR) deadline and the final deadline for outstanding Q4 2025–26 Super Guarantee Charge obligations.

Let’s untangle them together.

The key August 2026 dates at a glance

• Every payday: Super must be paid so it reaches each employee’s super fund within 7 business days of payday, subject to limited exceptions.
• 21 August 2026: Lodge and pay the July 2026 monthly activity statement, if your business reports monthly.
• 28 August 2026: Lodge the 2025–26 Taxable Payments Annual Report (TPAR), if it applies to your business.
• 28 August 2026: Lodge and pay an outstanding Q4 2025–26 Super Guarantee Charge statement, if required.
• From 1 July 2026: Businesses with GST turnover of $10 million or more may need full BAS reporting and accruals accounting; businesses with turnover of $20 million or more generally need monthly GST reporting.

The dates themselves are manageable. The cashflow impact is what deserves your attention.

1. Payday Super: your old quarterly buffer has disappeared

From 1 July 2026, employers must pay super every payday. The contribution must reach the employee’s super fund within seven business days of that payday.

That is a major shift for businesses that previously treated super as a quarterly obligation. The old approach allowed you to hold cash for longer and plan around four larger payments each year. Now, super is moving through your business alongside wages.

For many small businesses, this will be healthier for employees. It may also be healthier for the business because the obligation is visible more often. But visibility only helps if your systems and cashflow can keep up.

Ask yourself:

• Does each payroll run automatically create a super payment task?
• Are contributions being sent early enough to allow for processing and fund receipt?
• Do you know how much cash is committed to wages and super over the next four weeks?
• Have you tested what happens when a customer pays late?

A contribution being sent is not necessarily the same as the fund receiving it. Build in processing time rather than aiming for the edge of the seven-business-day window. The ATO’s Payday Super guidance explains the general rule and exceptions.

A SMART Payday Super objective

1. Set a weekly payroll control by 26 August.
   Specific: Record each payday, expected super amount and payment date in one shared calendar.
   Measurable: Confirm every contribution has been received by the employee’s fund within seven business days.
   Achievable: Schedule payments earlier than the deadline where possible.
   Relevant: Protect employee entitlements and reduce the risk of Super Guarantee Charge liabilities.
   Time-bound: Review the process after your next three payroll cycles.

Cashflow planning for the new rhythm

Your cashflow forecast should now show super as a regular outgoing, not a quarterly surprise.

If you pay weekly, model 52 smaller super payments. If you pay fortnightly, model 26. Then add wages, PAYG withholding, rent, software, suppliers and tax obligations around those dates.

This is where accurate bookkeeping becomes more than a compliance task. Clean, current records help you see the water level in the tank before it gets dangerously low.

2. 21 August: July monthly activity statement

If your business reports GST and PAYG withholding monthly, your July 2026 monthly activity statement is due on 21 August 2026.

That means you need to lodge and pay by the deadline. Don’t wait until the 20th if your books are still full of unreconciled transactions, missing receipts or unclear payroll entries.

Before lodging, check:

• All July bank accounts and payment platforms are reconciled.
• Sales invoices and customer receipts are recorded in the correct period.
• Business purchases have supporting documentation.
• Payroll, PAYG withholding and super records agree.
• GST-coded transactions have been reviewed rather than accepted blindly.
• Any unusual movements have an explanation.

A BAS is not just a form to submit to the ATO. It is a monthly story about how money moved through your business. Are sales growing? Are expenses rising faster than revenue? Are customers taking longer to pay? Are you collecting GST but spending it before the BAS is due?

Those are strategic questions, not just accounting questions.

Use the ATO activity statement guidance to confirm your obligations. If you’re unsure whether you report monthly or quarterly, check your ATO settings or speak with your BAS agent.

3. 28 August: TPAR for 2025–26

The Taxable Payments Annual Report for the 2025–26 financial year is due on 28 August 2026, if your business is required to lodge one.

TPAR generally applies to businesses that provide services in industries such as:

• Building and construction
• Cleaning
• Courier and road freight
• Information technology
• Security

The report includes payments made to contractors for relevant services. It helps the ATO compare what businesses report paying contractors with the income those contractors report.

Why creative agencies should pay attention

Creative agencies often work with freelancers, contractors, developers, photographers, copywriters, designers and production specialists. Contractor payments deserve a closer look, particularly where the agency provides IT, digital development or other services that fall within the TPAR rules.

However, paying freelancers does not automatically mean every creative agency must lodge a TPAR. The obligation depends on the services your business provides and the nature of the contractor arrangements.

By 28 August, review:

1. Your business activity: What services does your agency actually provide?
2. Contractor records: Who did you pay during 2025–26, and for what work?
3. ABN details: Are contractor ABNs and business names recorded accurately?
4. GST and invoices: Do your bookkeeping records clearly identify contractor payments?
5. Exemptions: Are any payments excluded under the ATO’s guidance?

The official ATO TPAR information is the right place to check the detailed rules. If the report applies, lodge it electronically: paper TPAR lodgments are no longer accepted.

4. 28 August: outstanding Q4 Super Guarantee Charge statements

The final August deadline also matters if your business did not pay the required super contributions for Q4 2025–26, covering 1 April to 30 June 2026, on time and in full.

In that situation, you generally need to lodge a Superannuation Guarantee Charge statement and pay the charge by 28 August 2026.

This is separate from getting your new Payday Super process right. It relates to the previous quarterly system and any unpaid or late Q4 obligation.

If you think there may be an issue, don’t bury the paperwork under a pile of “I’ll deal with it later” tasks. Check your payroll reports, super payment confirmations and employee contribution records now. The ATO’s Super Guarantee Charge guidance can help clarify what happens when contributions are late or unpaid.

5. GST reporting changes: check whether your turnover has crossed a threshold

The ATO is reviewing GST turnover and may move some businesses to the correct reporting method from 1 July 2026.

If your GST turnover has reached:

• $10 million or more: You may need to use full BAS reporting and account for GST on an accruals, or non-cash, basis.
• $20 million or more: You generally need to report GST monthly and lodge your BAS electronically.

These thresholds are not brand-new rules, but the ATO is taking a more active role in moving businesses that are using the wrong method.

This matters for growing businesses because accruals accounting can create a timing difference between recording a sale and receiving the cash. You may owe GST before your customer has paid you.

That is precisely why your cashflow planning needs to sit alongside your GST reporting. Profit on paper does not always equal money in the bank.

Review your current GST turnover, reporting cycle and accounting method. The ATO’s GST turnover guidance explains what may change and when to contact the ATO or your tax professional.

6. Industry insight: medical and allied health cashflow

Medical and allied health businesses have their own timing puzzles.

You may deliver a service today, submit a claim tomorrow and receive payment later. Medicare, private health and third-party claims can all create gaps between providing care and receiving cash. Add payroll, rent, equipment finance and now more frequent super payments, and your bank balance can feel disconnected from how busy the practice is.

I recommend setting a weekly rhythm:

• Review appointments delivered but not yet claimed.
• Track claims submitted but not yet paid.
• Follow up rejected or delayed claims quickly.
• Keep a separate view of payroll and super commitments.
• Forecast at least six to eight weeks ahead.

A busy practice can still experience a cashflow squeeze. Revenue is not the same as available cash: and knowing the difference gives you options.

Your end-of-August financial checklist

1. Protect payroll cash.
   Calculate the next four weeks of wages, super and PAYG withholding before approving discretionary spending.

2. Reconcile before reporting.
   Bring your July bookkeeping up to date before preparing the monthly activity statement.

3. Review contractor payments.
   Creative agencies and contractor-heavy businesses should check whether TPAR applies to their services and records.

4. Investigate old super issues.
   Confirm whether a Q4 2025–26 Super Guarantee Charge statement is required before 28 August.

5. Check GST turnover.
   If turnover is approaching $10 million or $20 million, review your GST method and reporting frequency now.

6. Create one visible deadline calendar.
   Include ATO dates, payroll dates, super processing dates, supplier payments and expected customer receipts.
