Late & multi-year tax returns

Behind on tax returns?

One year overdue or fifteen — we've handled it. Sydney's Chatswood-based late and multi-year tax return specialists since 1975. No judgment, and we seek penalty remission where there's genuine cause.

Clients across Australia and overseas, by phone, email and secure document upload.

Falling behind on tax returns is more common than people think — and it happens for all sorts of reasons. Time-poor contractors and tradies whose paperwork slipped behind another quarter, then another. Non-residents living abroad who still own an Australian property and didn't realise the lodgement obligation kept running. Business owners who lost a partner, a year, or both. People who've just received an ATO bill or amended assessment and want someone in their corner.

Whatever brought you here, the work is the same. Tell us what's happened, hand over whatever paperwork you have, and we take it from there — including any ATO correspondence you'd rather not handle yourself. No judgment, no perfect-records requirement.

We've successfully lodged thousands of overdue returns, including for clients fifteen-plus years behind. Where there's genuine cause, we apply for penalty remission, and many clients have had penalties reduced or remitted in full.

How we help

  • Lodge multiple years of returns in a single engagement — bulk catch-up
  • Apply to the ATO for penalty remission where genuine cause exists
  • Reconstruct your tax position from incomplete records using bank statements, ATO data and other available documentation
  • Respond to ATO warning letters and default assessments on your behalf
  • Set up payment arrangements with the ATO once returns are lodged
  • Catch up non-resident returns covering Australian rental income, capital gains and other ongoing obligations for clients living abroad
  • Handle Employee Share Scheme tangles, amended assessments and complicated prior-year items along the way

Whether you're one year behind or fifteen, the path forward is the same: get a clear picture, lodge what's outstanding, and let us handle the ATO from there.

What we check, and what you can prepare

How far behind you are changes what we look at first. It doesn't decide the outcome: penalties depend on how late each return is, whether it results in a refund or a bill, and the reasons for the delay.

1 year What we check Which return is outstanding on your ATO record, any lodgment reminders, and whether a refund or a bill is likely. What you can prepare Income statements (most are on your ATO record), bank interest, and receipts for work-related deductions.
2–5 years What we check All outstanding years together, ATO letters and any penalties already applied, and whether you'll need a payment arrangement. What you can prepare ATO letters, bank statements for each year, and records of work expenses or business income.
5+ years What we check Any default assessments already raised, which years the ATO requires, records to rebuild from bank and ATO data, and grounds for penalty remission. What you can prepare Whatever you have, ATO letters first. We rebuild the rest from bank statements and the ATO's own data.
Living overseas What we check Your residency status for each year, Australian rental income and capital gains, and the different non-resident rates (no tax-free threshold). What you can prepare The date you left Australia, rental statements from your property manager, and loan interest statements.

Five or more years behind

This is routine work for us. We start from your ATO record, which shows the outstanding years, any default assessments already raised and any penalties applied. Income statements, bank interest and many other items are already in the ATO's data, so missing paperwork rarely stops the work.

We then lodge every outstanding year together. That gives the ATO the full picture, which is the strongest basis for a penalty remission request or a payment arrangement, and we deal with the ATO for you throughout.

What to bring (or send through)

Any ATO letters or assessments you've received, payslips or income summaries you have, bank statements for the affected years, and any prior tax returns. Don't worry if records are incomplete — we work with what you have and reconstruct the rest.

Frequently asked

Late tax return questions

ATO figures last reviewed 19 October 2026.

What happens if I haven't lodged tax returns for 5+ years?
The ATO can charge a failure-to-lodge penalty of one penalty unit for every 28 days a return is overdue, up to five units per return. For individuals and small businesses that is currently up to $1,820 per return ($364 per unit from 1 July 2026). The ATO generally doesn't issue this penalty for a late tax return that results in a refund or nil result. It can also issue a default assessment based on its own estimate of your income. We've successfully lodged returns for clients 15+ years behind. Where there's genuine cause, we apply for penalty remission, and acting before the ATO does strengthens the case. We handle all ATO communication on your behalf.
Do I need to lodge if I earned under $18,200?
Not always. Australian residents with taxable income at or below the $18,200 tax-free threshold may not have to lodge, but you usually should if tax was withheld from your pay, so you can get it back. Non-residents get no tax-free threshold, so Australian income of any amount usually means a lodgement obligation. We can check your ATO record and confirm which years actually need lodging.
Can unlodged tax returns affect Centrelink, loans or insurance?
They can. Some Centrelink payments, including Family Tax Benefit, are reconciled against lodged returns, and lenders and insurers often ask for recent notices of assessment. Catching up usually clears these.
Can ATO penalties be waived or reduced?
Often, yes. The ATO can remit penalties in full or in part, and a genuine effort to get compliant counts. Where there's genuine cause, we apply for penalty remission, and many clients have had penalties reduced or remitted in full. Lodging all overdue years together and explaining the reason for the delay gives the strongest case.
Do I need all my paperwork from previous years?
No, you don't need perfect records. We can reconstruct your tax position using bank statements, ATO records and other available documentation. Many of our clients have incomplete paperwork — we work with what you have. The important thing is to start the process; we'll guide you through gathering what's needed.
How quickly can you lodge multiple years?
Urgent cases are prioritised. Most multi-year catch-ups are completed within 1-2 weeks, depending on complexity and the availability of records. We lodge all years together so you become compliant in one engagement.
Can you help if I've received ATO warning letters?
Yes. ATO warning letters are an opportunity to act before the situation escalates. We respond to the ATO on your behalf, explaining that you're working with a registered tax agent to become compliant. Acting before a default assessment or penalty notice keeps more options open. Bring any ATO letters to your first appointment — we'll handle communication from there.
What if I can't pay the tax debt immediately?
You don't need to pay the debt before lodging — in fact, you can't set up an ATO payment plan until returns are lodged. We focus on getting you compliant first. Once lodged, we can help you negotiate a payment arrangement that fits your situation.
I live overseas but still own property in Australia — do I need to lodge?
Generally yes. Non-residents with Australian rental income, capital gains exposure on Australian property, or other Australian-sourced income usually still have lodgement obligations — even after years abroad. Non-resident rules and tax rates differ from resident returns, and getting the residency timing right matters. We handle non-resident catch-ups regularly and can review your specific position before any lodgement.
