Tax Time 2026 covers the 2025–26 Australian income year, which runs from 1 July 2025 to 30 June 2026. If you are lodging your own individual tax return, the ATO due date is 31 October 2026; because 31 October falls on a Saturday, self-lodgers have until 11:59 pm local time on Monday, 2 November 2026.
For business owners, tax time is not only about lodging a return. It is the point where payroll, bookkeeping, receipts, reconciliations, and reporting must come together. This guide explains what to prepare, which deadlines may apply, and how organised finance support can reduce last-minute pressure.
This article is general information only. Tax outcomes depend on your structure, income, deductions, and circumstances. For tax advice or lodgment, speak with a registered tax agent or qualified adviser.
Key Tax Time 2026 Dates
The most important date for many individuals and sole traders is the individual tax return deadline. The ATO states that self-lodgers must lodge by 31 October, and where that date falls on a weekend, the deadline moves to the next business day.
| Situation | Key date | What it means |
|---|---|---|
| Individual tax return lodged yourself | 2 November 2026, 11:59 pm local time | The usual 31 October deadline falls on a Saturday, so the ATO deadline is the next business day. |
| Using a registered tax agent | Engage the agent by 31 October 2026 | Registered tax agents may have later lodgment schedules, but you generally need to be on their client list before 31 October. |
| Small company lodging its own return | Generally 28 February after year-end | Company due dates vary; the ATO notes that small companies generally lodge by 28 February, while outstanding prior-year returns can change the date to 31 October. |
| Company with prior-year returns outstanding | 31 October 2026 | The ATO lists 31 October 2026 as the lodgment date for certain 30 June balancing companies with prior-year returns outstanding. |
| Employers finalising STP data | 14 July 2026 | Employers needed to finalise Single Touch Payroll data for 2025–26 so employees have the information needed for their returns |
Who Needs to Lodge a Tax Return?
Whether you need to lodge depends on your circumstances. Individuals may need to lodge if they received taxable income, had tax withheld, or meet other ATO lodgment requirements. The ATO provides a dedicated guide to help taxpayers determine whether an individual return is required for 2025–26.
Business owners should also consider their structure:
- Sole traders generally report business income and deductions through their individual tax return.
- Companies lodge a separate company tax return; the ATO notes that a company needs to lodge a company tax return where it operates through a company structure.
- Partnerships and trusts may have separate lodgment and reporting obligations, depending on their arrangements.
- Employers must ensure payroll and STP information is complete and accurate before employees lodge their own returns.
Records Australian Business Owners Should Prepare
Strong recordkeeping is the foundation of a smooth tax time. Before lodging, gather the documents that support income, expenses, payroll, and asset purchases.
Income and sales records
Collect invoices, sales reports, payment-gateway summaries, bank deposits, and records of other income. Reconcile these against your accounting software and bank statements so your reported income matches your financial records.
Expense and deduction records
Keep receipts, supplier invoices, subscription records, vehicle and travel documentation, and evidence for any asset purchases. Only claim expenses that relate to earning your business income and that you can substantiate.
Payroll and contractor information
Review payroll summaries, superannuation records, PAYG withholding, and contractor payment details. Employers should confirm that STP information has been finalised and that employee records are accurate.
Bank and accounting reconciliations
Complete bank, credit card, loan, and payment-processor reconciliations. Clean reconciliations make it easier for your accountant or registered tax agent to review the numbers and identify missing transactions.
Common Tax Time Mistakes to Avoid
- Leaving reconciliation until the deadline. Unmatched transactions can delay preparation and create avoidable questions later.
- Missing income records. Check all sales channels, payment platforms, interest, dividends, and other income sources.
- Claiming unsupported expenses. Keep documentation for every business expense you intend to claim.
- Using personal and business accounts interchangeably. Separate records make it easier to identify business transactions.
- Waiting until October to engage a tax agent. If you want an agent-managed lodgment schedule, you generally need to engage them before 31 October.
DIY Lodgment vs Registered Tax Agent
| Option | Best suited to | Main advantage | Key consideration |
|---|---|---|---|
| Lodging yourself | Straightforward individual returns | You manage the process directly through ATO online services. | You must meet the self-lodgment deadline of 2 November 2026. |
| Registered tax agent | Business owners, investors, or complex affairs | Agents may have later lodgment schedules and can review your position. | You generally need to engage the agent before 31 October. |
| Outsourced finance support | Businesses with high transaction volumes | Helps keep bookkeeping, reconciliations, and records current throughout the year. | Support staff work under your processes; tax advice and lodgment remain with your registered tax agent. |
How Outsourced Accounting Support Helps at Tax Time
Tax time becomes easier when your finance records are accurate before the deadline approaches.

This support is provided under your processes and supervision; it does not replace advice or lodgment from a registered tax agent.
