TITLE: 10 August Australia Tax Compliance Checklist: Key ATO Updates for Your Business
The Australian Taxation Office (ATO) has issued several important compliance signals for Australian businesses on 10 August 2026.
The key developments affect private company loans, contractor income reporting, tax debt collection and the final electronic lodgment date for the April–June 2026 activity statement.
Use this checklist to identify what applies to your business and what you need to complete next.
Act now: Your 10 August Australia tax compliance checklist
Before the next deadline, complete these checks:
- Review Division 7A loans and update calculations using the new 8.77% benchmark interest rate for the 2026–27 income year.
- Check TPAR-related income before lodging an individual or contractor tax return.
- Confirm your Q4 activity statement status and lodge or pay by 11 August 2026 if the electronic concession applies to you.
- Review outstanding ATO debts and respond promptly to any payment reminder, garnishee notice or director penalty notice.
- Reconcile your accounting records so your BAS, GST, PAYG and year-end reporting are based on complete data.
These actions will help you avoid omissions, incorrect repayment calculations, interest costs and escalation by the ATO.
Division 7A: Benchmark interest rate increases to 8.77%
The ATO has confirmed that the Division 7A benchmark interest rate will rise to 8.77% for the 2026–27 income year.
This is an increase from 8.37% for the 2025–26 income year. The rate is based on the Reserve Bank of Australia’s variable housing loan indicator rate.
The rate is relevant to complying private company loans made to shareholders or their associates. It also affects the minimum yearly repayments required under a complying Division 7A loan agreement.
Read the ATO’s Division 7A benchmark interest rate guidance for the official rate table and related information.
Review these Division 7A items now
If your company has lent money or provided financial benefits to a shareholder or associate, check:
- The loan agreement
Confirm that the loan is documented correctly and meets the requirements for a complying Division 7A loan. - The applicable interest rate
Use 8.77% when calculating interest for the 2026–27 income year. - The minimum yearly repayment
Recalculate the repayment amount. A higher benchmark rate may increase the required repayment. - The repayment history
Check that previous minimum yearly repayments were made by the relevant deadline and were not later withdrawn or redirected. - Company records
Reconcile the director’s loan account, general ledger and bank transactions. This will help you identify private expenses, drawings or unpaid amounts that may require attention.
Do not treat a company loan as an informal arrangement. If the Division 7A requirements are not met, the amount may be treated as an unfranked dividend and included in the recipient’s assessable income.
A structured monthly or quarterly review will give you time to correct records before year-end reporting and tax calculations are completed.
TPAR: Wait until after 28 August before lodging where possible
The ATO is warning that up to $1 billion in Taxable Payments Annual Report (TPAR) payments may be omitted or under-reported in 2026.
For Tax Time 2026, TPAR information is being used to pre-fill contractor business income for eligible individuals. The ATO expects approximately $21 billion in contractor payments to be pre-filled for around 700,000 sole traders and individuals in business.
However, the information may not be complete until reporting businesses have lodged their TPARs.
The ATO is encouraging contractors to wait until after 28 August 2026 before lodging if they receive payments that may be reported through the TPAR system. Waiting will give you a better opportunity to access complete pre-filled information and reduce the risk of amendments later.
You can review the ATO’s official pre-fill information for contractors before finalising your return.
Check your TPAR data before lodging
Use this process:
- Identify TPAR income sources. Review payments received from businesses that may have reporting obligations.
- Check pre-filled information. Compare the ATO data with your accounting records and bank statements.
- Include income that is not pre-filled. Not all business income appears in TPAR data.
- Check GST treatment. Confirm whether amounts are recorded as GST-inclusive or GST-exclusive, where applicable.
- Review expenses separately. TPAR pre-fill does not replace your responsibility to record eligible business expenses accurately.
- Keep supporting records. Retain invoices, contracts, payment reports and reconciliations in case the ATO requests evidence.
The TPAR rules may affect contractors in areas such as construction, cleaning, courier and road freight services, information technology, security and related industries.
Do not assume that missing pre-fill data means income does not need to be declared. Your own records remain the primary source for complete reporting.
Activity statement deadline: Lodge electronically by 11 August
The electronic lodgment deadline for the Quarter 4 activity statement covering April to June 2026 is 11 August 2026 for eligible businesses lodging electronically.
This deadline may apply where you use the two-week electronic lodgment concession. The standard quarterly deadline was 28 July 2026.
The ATO’s August due dates guidance confirms the 11 August deadline for Quarter 4 activity statements lodged electronically.
Complete your Q4 activity statement checklist
Before lodging, confirm:
- Sales and income are reconciled to your bookkeeping system.
- GST collected agrees with your sales records.
- GST credits are supported by valid tax invoices.
- Imports, exports and cross-border transactions have been reviewed.
- PAYG instalments have been checked.
- PAYG withholding figures agree with payroll records.
- Adjustments and private-use calculations are documented.
- The amount payable is available for payment by the due date.
If a registered BAS agent is lodging your activity statement under the relevant agent program, a different lodgment date may apply. Confirm the date with your agent instead of assuming that 11 August applies to every business.
Lodging on time remains important even if you cannot pay the full amount immediately. Late lodgment can create penalties and may increase the risk of firmer collection action.
ATO debt collection: Expect faster escalation
The ATO is returning to a firmer approach to tax debt collection. Australian businesses should not assume that pandemic-era flexibility will continue.
