When is the absolute deadline to file my 2025-26 tax return?
It depends on how you lodge. If you are self-lodging via myTax, your deadline is 31 October 2026. If you use a registered tax agent (like our partners at Accountants Direct), you must be on their books by 31 October, but your actual filing deadline is typically extended to 15 May 2027.
What documents do I need to “gather” for my income records?
You need more than just your bank balance. You should have:
Can I claim a deduction for a “Work-from-Home” lunch or coffee?
Generally, no. The ATO considers daily meals a private expense. However, if you are traveling overnight for a business trip or attending a seminar, those meals may become deductible. Always check the “Travel and Subsistence” rules for your specific industry.
What is the “Instant Asset Write-Off” for 2026?
For the 2025–26 financial year, the Instant Asset Write-Off threshold is $20,000. If you buy a piece of equipment for your business (like a computer or specialized tools) that costs less than $20k, you can claim the full deduction this year instead of spreading it out over several years.
Should I file even if I didn’t make a profit this year?
Yes. If you carried on a business, you must lodge a tax return even if your income was zero or you made a loss. Reporting a loss can actually be beneficial, as you may be able to “carry it forward” to reduce your tax bill in future, more profitable years.
How does Sole’s partnership with Accountants Direct work?
Sole makes your data “Accountant-Ready.” You can securely share your financial reports directly from the app, which saves your accountant time and saves you money on billable hours. Professional oversight ensures you’re not just compliant, but that you haven’t missed any “hidden” deductions.
