When Can You Lodge Your Tax Return in 2026 (And How Long Until Your Refund

Every year, the same thing happens: the calendar flips to 1 July, hundreds of thousands of Australians log into myTax on day one, lodge immediately — and then spend weeks wondering why their return got flagged, amended, or delayed. The honest answer to "when can I lodge?" and "when should I lodge?" are often different dates, and knowing the difference can save you a lot of frustration.

When does tax time officially start?

The 2025-26 financial year ends on 30 June 2026, and the ATO opens myTax for the new financial year on 1 July 2026. Technically, you can start entering details from this date.

But "open" doesn't mean "ready." The ATO's prefill system — which automatically pulls in your income statement, bank interest, dividend statements, and private health insurance details — takes time to populate as employers, banks, and other institutions report their data.

Why lodging in the first week of July is usually a mistake

If you lodge on 1 or 2 July, here's what's often missing from your prefill:

Your income statement may not yet be marked "Tax ready" by your employer (even though it might show as "Year to date")
Bank interest from savings accounts and term deposits often hasn't been reported yet
Dividend and managed fund statements frequently aren't finalised until later in July or August
Private health insurance statements can take until mid-August to appear

If you lodge before this data arrives and your return is missing income, the ATO's data-matching program will likely catch it later — and you may need to lodge an amendment, which adds delay and, in some cases, can result in a small additional tax bill plus interest.

So when should you lodge?

A practical rule of thumb:

Employees with straightforward income (one employer, basic bank interest): wait until your income statement shows "Tax ready" in myGov, usually mid-to-late July
If you have dividends, managed funds, or multiple income sources: prefill is often more reliable from early-to-mid August
If you have a rental property, capital gains, or are self-employed: you'll likely be preparing these figures yourself regardless, so prefill timing matters less — but it's still worth checking your income statement is finalised before you lodge

Being a week or two later than 1 July costs you nothing. Lodging early and having to amend costs you time, and potentially triggers a closer look at your return.

Key deadlines for the 2025-26 tax year

Action	Deadline
myTax opens for 2025-26 returns	1 July 2026
Most income statements "Tax ready"	Mid-to-late July 2026
Self-lodged return deadline (myTax)	31 October 2026
Deadline to register with a tax agent (to access their extended deadline)	31 October 2026
Extended deadline via registered tax agent	Generally 15 May 2027 (some agents may have concessional dates)

If you've used a tax agent in a prior year and plan to again, you generally need to be on their books before 31 October to access the extended deadline — don't assume it applies automatically if you're a new client signing up in November.

How long does it actually take to get your refund?

Once you've lodged, processing times depend heavily on how you lodge and whether your return is straightforward:

Lodged online via myTax: most refunds are processed within around 2 weeks (roughly 12 business days) of lodgment, assuming no issues
Lodged via a registered tax agent: similar timeframes once the agent submits your return, though agents may batch lodgments during busy periods
Lodged on paper: significantly slower — often up to 50 days (around 10 weeks), since paper returns require manual processing

What can slow your refund down

Even an online return can take longer than expected if:

It's your first tax return — the ATO often does additional identity and bank detail checks
You're claiming unusually high deductions relative to your income or occupation — this can trigger an automated review
It's the first year you've reported a rental property or a capital gains event — these are common review triggers
You have outstanding debts to government agencies (Centrelink, child support, HECS-HELP) — your refund may be automatically offset against these before you receive the balance
Your bank details are incorrect or outdated in myGov — this is one of the most common (and easily avoidable) delays
You lodge during peak season (mid-July through October), when ATO volumes are at their highest

None of these mean you've done anything wrong — they're just things that move your return from "automatic" to "needs a look."

How to track your refund

You can check progress at any time via myGov → Australian Taxation Office → Tax → Income tax → lodgments. Status will move from "In progress – processing" to "In progress – under review" (if flagged) to "Issued" once your assessment and refund are finalised.

Frequently asked questions

Can I lodge my tax return before 1 July?

No. The ATO's online lodgment system for the new financial year opens on 1 July. You can gather documents and estimate your position beforehand, but you can't formally lodge earlier.

Is it true that lodging early increases my audit risk?

Not exactly — but lodging before your prefill data is complete increases the chance your return is missing information, which can lead to an amendment or a closer review later. Waiting a couple of weeks for "Tax ready" status reduces this risk significantly.

How long after lodging will I get my refund?

For most people lodging online with a straightforward return, refunds are typically issued within about two weeks. Paper lodgments can take up to 10 weeks.

What if I owe money instead of getting a refund?

Your Notice of Assessment will show the amount owing and the due date — this is usually several weeks after your assessment is issued, giving you time to arrange payment.

Does using a tax agent get me a faster refund?

Not necessarily faster processing once lodged, but agents can help ensure your return is complete and accurate the first time, which avoids the delays caused by amendments. Using a registered agent also gives you a later lodgment deadline.
