This guide walks you through everything you need to know to get your tax return sorted on time without the stress.

Quick Summary: Key Points for Lodging Your 2026 Tax Return

  • Tax year: 1 July 2025 to 30 June 2026
  • Self-lodgement deadline: 31 October 2026 is the final date to lodge your tax return yourself without penalty.
  • Tax agent deadline: If you use a registered tax agent and register with them by 31 October 2026, you can usually lodge as late as May 2027.
  • Most Australians lodge via myTax on myGov: This online portal is free and straightforward, plus it pre-fills much of your info.
  • 2025-26 tax rates: The tax-free threshold is $18,200. Income between $18,201 and $45,000 is taxed at 16.5%. The top marginal rate is 45% on income over $180,000, plus a 2% Medicare levy applies on most taxable income.
  • Common deductions: Work-from-home expenses calculated at 67 cents per hour, car expenses, uniforms, tools, and self-education costs related to your job.
  • Keep your records: To substantiate claims, keep receipts, logs, diaries, and payment summaries for at least five years.
  • HELP debt repayments: From 1 July 2025, repayments start when your income hits $67,000, with a new marginal rate system gradually increasing your repayment percentage as income grows.

Prerequisites Before You Start

Before you lodge your tax return, there’s a bit of prep to get through. Having the right materials ready will save you time and headaches.

  • MyGov account linked to ATO: You need a myGov account linked to the ATO to lodge online. Create one at Https://my.gov.au if you haven’t already. Linking your ATO account is a simple process involving verifying your identity with details like your tax file number and personal info.
  • Records and documents: Gather your payment summaries or income statements from employers, bank statements showing interest earned, dividend statements, health insurance details for the private health insurance rebate, and any receipts or evidence of deductions you want to claim.
  • Check your details on ATO pre-fill: The ATO automatically pre-fills income data from employers, banks, health funds, and government payments into your myTax return. But it’s crucial to review all pre-filled info carefully — sometimes data might be missing, delayed, or incorrect, especially if you changed jobs or had multiple income sources.
  • Keep work-related expense records: For deductions like work-from-home expenses, car use, tools, or self-education, maintain detailed logs, receipts, diaries, and travel records. The ATO requires evidence to substantiate your claims in case of an audit. For example, work-from-home deductions at 67 cents per hour cover electricity, internet, and phone use during work hours.

Step-by-Step Guide to Lodging Your Tax Return in Australia 2026

1. Log into myGov and Access myTax

Go to Https://my.gov.au and sign in with your credentials. If you haven’t linked the ATO to your myGov account, you’ll be prompted to do so. This linking takes a few minutes and involves confirming your identity with your tax file number, date of birth, and other personal info. Once linked, select the “ATO” service from your myGov dashboard, then choose the option to lodge your tax return using myTax.

2. Review Your Pre-Filled Information

MyTax will automatically load pre-filled information from your employers, banks, health funds, and government agencies. This includes salary and wages, bank interest, dividend payments, government allowances, and private health insurance details. Take your time to carefully review each section — check that all your income streams are accounted for and the amounts match your records. If anything’s missing, you’ll need to add it manually.

3. Add Any Extra Income Not Pre-Filled

If you earned income that isn’t automatically included — like cash jobs, freelancing, or rental income — enter it yourself. The ATO expects you to declare all income, even if it’s not reported to them. Also include any foreign income, capital gains from selling assets, or government payments not pre-filled.

4. Claim Your Deductions

Work through the deductions section carefully. Common claims include:

  • Work-from-home expenses at 67 cents per hour for the 2025-26 year — log your hours and multiply accordingly.
  • Car expenses if you use your vehicle for work (not including commuting) — you’ll need mileage logs and receipts.
  • Uniforms, protective clothing, and tools related to your job.
  • Self-education expenses if the course relates directly to your current job.
  • Donations to registered charities.

Remember, every claim requires evidence. Upload digital copies of receipts or keep them handy in case the ATO asks later.

5. Review Offsets and Rebates

Check if you’re eligible for tax offsets like the low-income tax offset or private health insurance rebate. These can reduce your tax payable. The ATO’s myTax system will often calculate these automatically but verify your eligibility.

6. Confirm Your Bank Details

Make sure your bank account details are up to date for any refund payments. You can enter or update your account details within myTax.

7. Submit Your Tax Return

Once everything looks correct, submit your tax return through myTax. You’ll receive an ATO receipt number confirming lodgement. Keep this number for your records.

8. Keep Records After Lodgement

Hold onto all your tax records — payment summaries, receipts, logs, and statements — for at least five years. The ATO can audit returns from previous years, so having your paperwork ready is essential.

Tips for a Smooth Tax Return Experience

  • Start early — don’t leave your tax return until the last minute. You can lodge as soon as you have all your documents, typically from July 1.
  • Use the ATO’s online calculators and tools to estimate your refund or tax payable before lodging.
  • If your tax affairs are complex, consider registering with a tax agent before 31 October 2026 to get extended deadlines.
  • Check the ATO website regularly for any updates to tax rates, thresholds, or deduction rules for the 2025-26 year.
  • If you get stuck, the ATO offers phone support and online chat during business hours.
  • Watch out for scams — the ATO never asks for payment via email or phone calls. Always use official websites like Https://ato.gov.au and myGov.

Common Mistakes to Avoid When Lodging Your Tax Return

  • Failing to lodge by 31 October 2026, which can result in penalties and interest charges.
  • Not checking pre-filled information — missing income can trigger ATO reviews.
  • Claiming deductions without proper records or receipts.
  • Overlooking HELP debt repayment obligations if your income exceeds $67,000.
  • Entering incorrect bank details, which delays refunds.
  • Ignoring eligibility for tax offsets or rebates that could reduce your tax bill.
  • Relying on memory instead of keeping detailed logs for car or work-from-home expenses.

Lodging your tax return in Australia for the 2025-26 year doesn’t have to be a headache. Using myTax through myGov is the simplest way for most people. Just make sure you check your pre-filled info carefully, keep your records organised, and lodge on time by 31 October 2026 to avoid penalties.
