Late or Overdue? How to Lodge a Late Tax Return in 2025 (Even If You’re Years Behind)

It’s Not Too Late to Get Back on Track 

Missed a tax deadline or simply didn’t have time to get it done? Whatever the reason you fell behind, ITP can help! The good news is, it’s not too late. After 50+ years of helping Australians navigate their tax obligations, we’ve seen every scenario imaginable, and we’ve successfully helped thousands catch up on their overdue returns.

Whether you’re one year behind or several years overdue, ITP can help you ease your way through the process and lodge your tax return with the ATO stress-free. We’ve even helped clients who hadn’t lodged for over a decade get back on track without crippling penalties.

The reality is that life gets in the way sometimes. Medical emergencies, family crises, business pressures, or simply feeling overwhelmed by the paperwork, we understand. What matters now is taking action to resolve your situation and potentially claim refunds you may be entitled to.

Why Lodging Your Past Returns Matters More Than You Think

Staying compliant with the ATO isn’t just about avoiding penalties, it’s about protecting your financial future and accessing entitlements you may be missing. After five decades helping Australians manage their tax affairs, we’ve seen how unresolved tax issues can impact every area of life.

The hidden costs of delayed lodgement include:

  • Loss of family tax benefits and government support payments
  • Inability to access superannuation co-contributions
  • Blocked mortgage applications and credit assessments
  • Visa complications for temporary residents
  • Accumulated interest on tax debts
  • Restricted access to Centrelink benefits

The costs can be significant — and that’s before we’ve even begun to talk about the penalties! Not to worry, though. We regularly help clients recover thousands in missed refunds from previous years, and importantly, get back on track and avoid penalties.

ITP’s expertise makes the difference: With our direct ATO liaison capabilities and specialist knowledge, we can often negotiate penalty reductions or complete remissions, turning a stressful situation into a positive outcome.

Our registered tax agents have the authority and experience to represent you directly with the ATO, often achieving results that individual taxpayers struggle to obtain on their own.

ATO Penalties for Late Lodgement: 2024-25 Update

The ATO may impose fees and penalties for late tax returns through their ‘Failure to Lodge on time penalty’ (FTL). Understanding these penalties helps you make informed decisions about your next steps.

Current penalty structure for 2024-25:

  • One penalty unit: $330 per 28-day period overdue (updated from previous rates)
  • Maximum for individuals: Five penalty units ($1,650 for small entities)
  • Medium entities: Penalty multiplied by two ($660 per period, max $3,300)
  • Large entities: Penalty multiplied by five ($1,650 per period, max $8,250)

Medium entities are those that withhold PAYG or have assessable income or current GST turnover between $1 million and $20 million.

Large entities are those with assessable income or current GST turnover of $20 million or more.

Significant global entities face penalties multiplied by 500 — a substantial deterrent for multinational corporations.

When penalties apply:

  • You have multiple outstanding tax returns
  • Poor lodgement history with the ATO
  • Haven’t complied with lodgement requirements

Important protections available:

  • Safe harbour provisions: If you provided all relevant information to your tax agent on time, you may be protected from penalties even if the agent failed to lodge due to their error
  • Penalty remission: The ATO has discretion to reduce or completely remit penalties for genuine reasons such as natural disasters, serious illness, or other extenuating circumstances

Interest charges for tax debts:

  • General Interest Charge (GIC): Currently 11.17% annually on unpaid tax debts
  • Shortfall Interest Charge (SIC): Currently 7.17% annually on underpaid amounts

Pro Tax Tip: If you owe no tax or are entitled to receive a tax refund, the ATO typically does not apply a penalty. This is crucial — many people avoid lodging because they fear penalties, not realising they may actually be entitled to refunds.

ITP’s penalty success rate: Our tax accountants have lodged thousands of late or prior years’ tax returns successfully without penalty. In cases where penalties have applied, we’ve successfully reduced or completely negated them through professional ATO negotiation. While we can’t guarantee you won’t receive a penalty, we regularly liaise with the ATO and work with both parties for the best possible outcome.

Do You Need to Lodge? What the ATO Requires in 2025

If you earn over $18,200 annually, you’ll need to lodge a tax return. (You can use the ATO’s ‘Do I need to lodge a tax return?’ tool if you’re not sure.) However, lodgement requirements extend beyond just income thresholds, and many people are surprised by situations that trigger lodgement obligations.

You must lodge a tax return if you:

  • Earned more than $18,200 in the financial year
  • Had tax withheld from your income (regardless of amount)
  • Made capital gains during the year
  • Operated a business or had ABN income
  • Received foreign income as an Australian tax resident
  • Had reportable fringe benefits or reportable super contributions

Even below $18,200, you may need to lodge if:

  • You had tax deducted from government payments
  • You’re entitled to government benefits or family assistance
  • You want to claim deductions that create a refund
  • You received dividends with franking credits

Non-lodgement advice: If you earned below $18,200 and had no tax withheld, you may still need to submit ‘non-lodgement advice’ to the ATO. This ensures you don’t have an outstanding record and maintains your eligibility for government benefits and super co-contributions. 

The complexity factor: Tax lodgement requirements have become increasingly complex with the gig economy, cryptocurrency trading, and remote work arrangements. When in doubt, professional advice ensures you meet all obligations while maximising your refund potential.

What to Expect: How to Lodge a Late Tax Return with ITP

We can check to see if you have missed any tax returns and your lodgement status. Registered tax agents have access to tax records that most cannot access through direct portals with the ATO. You’ll just need to tell us your Tax File Number (TFN) or your Notice of Assessment or ATO reference number when you call.

Our comprehensive process includes:

Step 1: Lodgement History Review

We’ll check your complete lodgement status and identify all outstanding returns. Many clients are surprised to discover they’re missing returns from years they thought were complete.

Step 2: Income Data Access

From 2001 onwards, our tax accountants can access your employer payment summaries, bank interest income, dividend income, and private health insurance information. This historical data often reveals income sources clients had forgotten about.

Step 3: Deduction Reconstruction

Your tax claims can be made as normal. While you should gather receipts if available, our tax accountants will use ATO data access to reconstruct legitimate deductions where documentation is missing. We’ll advise what claims you can and can’t make based on available evidence.

Step 4: Refund Maximisation

ITP tax accountants work hard to maximise your outstanding years’ tax refunds. Generally, the more work-related expenses you can substantiate, the larger your refund. We know exactly what the ATO accepts and how to present claims for best results.

Step 5: ATO Liaison

If penalties apply or payment arrangements are needed, we handle the ATO communication on your behalf. Our established relationships and negotiation experience often achieve better outcomes than individual taxpayers can secure.

Multiple years lodged efficiently: We can process several years simultaneously, streamlining the entire catch-up process and getting you current faster than lodging individually.

Pro Tax Tip: ITP can often help reduce or completely cancel penalties through professional ATO negotiation, turning potential financial stress into tax refund opportunities.

Our standard tax return fees apply and can be deducted directly from your refund — no upfront payment required.

What Information You’ll Need to Provide

Gathering information for late returns is often easier than expected, thanks to modern ATO data systems and our professional access capabilities.

Essential information:

  • Tax File Number (TFN)
  • Previous Notices of Assessment (if available)
  • Employment details for relevant years
  • Bank account details for refund payments
  • Private health insurance information
  • Current contact details

Helpful but not mandatory:

  • Receipts for work-related expenses
  • Investment statements and dividend notices
  • Rental property income and expense records
  • Business income and expense documentation
  • Medical and charitable donation receipts

Professional advantage: Registered agents have access to pre-filled data and historical records that significantly simplify the process. We can often reconstruct your tax position even with limited documentation.

Missing paperwork isn’t a barrier. We regularly help clients who’ve lost paperwork due to house moves, relationship breakdowns, or simply time. Our ATO data access and professional experience can usually bridge these gaps effectively.

Digital record keeping: For current and future years, we recommend digital storage solutions for all tax-related documents. This prevents documentation loss and streamlines future lodgements.

We’ve even written a super helpful guide about how to maximise your deductions and potentially increase your tax refund!

Don’t Put it Off Another Year: Get it Sorted Today

Keeping your tax returns up to date means you’ll catch up with other entitlements, such as superannuation co-contributions and family tax benefits that many people miss by staying non-compliant.

The cost of delay compounds: Every year you postpone catching up is another year of potential refunds unclaimed, benefits missed, and stress accumulated. The “perfect time” to address overdue returns never arrives — but the relief of resolving them is immediate.

The best time to get your tax sorted was last year. The second-best time is today.

Your next steps are simple:

  1. Contact ITP to discuss your specific situation
  2. Provide basic information for lodgement history review
  3. Schedule a consultation that suits your preference
  4. Let our professionals handle the complexity while you focus on moving forward 

Don’t let another tax season pass with unresolved returns. The longer you wait, the more complex the situation becomes, and the more opportunities you miss.
