2026 Ultimate Guide to Lodging Your Australian Tax Return via myGov: Maximize Your Refund Legally

How to lodge 2026 ATO tax return via myGov


Last updated: June 2026  |  Reading time: 12 min

Tax time is one of those things that sneaks up on you every year. One minute it's April, and suddenly it's late June and your colleagues are all talking about what they're doing with their refund — a holiday to Bali, paying off the credit card, chucking it into the offset account.

A friend of mine got stung a few years back. She lodged the day July 1 hit, didn't wait for her income statement to say "Tax Ready," and ended up with pre-filled data that was off by nearly $3,000 in wages. The ATO flagged it, she had to amend, and her refund took an extra six weeks. Not a fun experience. The lesson she passed on: slow down by two weeks, and it saves you months of headaches.

This guide covers everything — who needs to lodge, what to gather, the exact steps inside myGov, and the deductions most people miss.


Do You Actually Need to Lodge?

Most people do. Here's the short version:

  • You earned more than $18,200 from any source → lodge.
  • Tax was withheld from your pay even if you earned under $18,200 → lodge (to get it back).
  • You're a foreign resident or on a working holiday visa and earned any Australian income → lodge.
  • You received government payments like JobSeeker or parental leave → lodge.

If you genuinely earned nothing and had nothing withheld, you can submit a "non-lodgement advice" through myGov instead.


Before You Log In: Get This Ready First

Logging in without your documents is how you end up with a half-finished return sitting in draft for three weeks. Have these on hand:

The essentials

  • Tax File Number (TFN) — 9 digits, on your payslips or old notices of assessment
  • myGov login (or set one up at my.gov.au)
  • BSB + bank account number for your refund deposit
  • Medicare card or driver's licence to link the ATO if you haven't already

Income documents

  • Income statements from employers (visible in your ATO portal once marked "Tax Ready")
  • Bank interest summaries
  • Dividend and managed fund statements if you hold ASX shares or ETFs
  • Any rental income records

Deduction receipts

  • Work-related expense receipts (digital is fine — a photo counts)
  • Donation receipts from registered DGRs
  • Income protection insurance statements
  • Union or professional association fee invoices
  • Self-education costs if the course relates directly to your current job
Worth knowing: Most employers, banks, and health funds don't finalise their data until mid-July — sometimes later. Watch for the green "Tax Ready" status next to your income statement in the ATO portal before you submit. Filing before that label appears is the single most common cause of amended returns.

Step-by-Step: Lodging via myGov

Step 1 — Link myGov to the ATO (first time only)

Go to my.gov.au, sign in, and hit Linked Services. Select ATO and follow the prompts. You'll verify your identity using two pieces of information the ATO already holds — usually something from a previous notice of assessment, your super fund, or a bank account where you've received refunds. Takes about five minutes.

Step 2 — Start your return

Once inside the ATO section, look for the prompt to lodge your 2025–26 return. Click Lodge, then work through it section by section. Start with personal details — current address, contact number, and especially your bank account. An incorrect BSB is one of the most avoidable delays in the whole process.

Step 3 — Review your pre-filled income

In 2026, the ATO auto-populates wages from employers, interest from banks, dividends, government payments, and private health fund details. Your job is to verify, not just accept. Cross-check the gross wages and tax withheld figures against your actual payslips. If something's missing — a previous job, a bank account — you can manually add it.

Step 4 — Claim your deductions

This is where you actually put money back in your pocket. The ATO doesn't volunteer deductions — you have to claim them.

Work-related car expenses
If you drive for work (not your regular commute — that doesn't count), you can use:

  • Cents per kilometre method: 88 cents/km, up to 5,000 km, no logbook needed
  • Logbook method: requires a 12-week logbook but covers a percentage of all actual car costs — better if you drive often for work

Working from home (WFH)
The fixed rate sits at 70 cents per hour worked from home in 2025–26. It covers electricity, gas, internet, phone, and stationery in one hit. You need a timesheet, roster, or diary showing your hours. If you have unusually high bills because you work from home full-time, look at the actual cost method — more paperwork, but potentially a bigger deduction.

Clothing and uniforms
Occupation-specific clothing (scrubs, hi-vis, chef's whites) and registered logo uniforms are claimable, including washing costs. Generic business wear is not, even if your employer has a dress code.

The $300 rule
If your total work-related expenses are $300 or under, no receipts required. But you still need to have spent the money and be able to explain what it was for if asked.

Other things people commonly miss:

  • Income protection insurance premiums (separate from super fund cover)
  • Union fees and professional memberships
  • Work-related subscriptions and software
  • Self-education costs tied to improving skills in your current role
  • Charitable donations over $2 to registered DGRs

What the ATO Is Watching in 2026

The ATO's data-matching in 2026 cross-references income from employers, banks, share registries, rental platforms, and government agencies automatically. A few things that tend to trigger a closer look:

Common audit triggers:
  • Claiming WFH expenses and separately claiming internet or electricity — you can't do both under the fixed rate method. It's already included.
  • Claiming daily travel between home and your regular workplace. Unless your home is a genuine place of business or you carry bulky equipment with no storage at work, the commute isn't deductible.
  • Deductions that seem disproportionate to your income — if you earn $60,000 and claim $15,000 in work expenses, expect scrutiny.

The rule is simple: if you spent it, it genuinely relates to earning your income, and you can prove it — claim it. If any of those three don't apply, don't.


Common Questions

What's the lodgement deadline?

October 31, 2026 if you're lodging yourself via myGov. If you want to use a registered tax agent, engage them before October 31 to access their extended lodgement program, which can push your deadline into 2027.

I made a mistake after submitting — now what?

Once the ATO has processed your return, log back in, go to your tax history, and click Amend. You can fix errors or add forgotten deductions. Don't leave it — particularly if the mistake means you underpaid.

Can I claim my private health insurance premium?

No, the premium itself isn't deductible. But entering your health insurance details still matters — it removes the Medicare Levy Surcharge if you'd otherwise be subject to it, and it calculates your rebate entitlement.

When does my income statement become "Tax Ready"?

Most are finalised by late July. Some larger employers take until early August. Check the ATO portal rather than assuming — lodging before it's ready is the most common mistake first-time filers make.
