ATO late lodgement penalty: up to $364 per 28 days, capped at $1,820 per document · interest 11.43% p.a. compounding daily · See how to remit them →
The best way to lodge multiple years of tax returns is together, as a single package through a registered tax agent, paired with one consolidated penalty remission request. Lodging years one by one drip-feeds the ATO a messy compliance story; lodging them together presents a clean "I've come forward and fixed everything" narrative - which is exactly what penalty remission decisions reward.
Why the package approach wins
Each return interacts with the others. Losses carry forward. HECS/HELP balances update year to year. Medicare levy surcharge and offsets depend on prior-year data. Lodging in the correct chronological order with consistent figures avoids the amendment loops that plague DIY multi-year lodgers. It also means a single remission case covering all years, rather than five separate penalty fights.
What it looks like with TaxNudge
One client authority gives us your full lodgement list. We prepare every outstanding year - typically 5 to 15 working days depending on complexity - then lodge them in sequence over a matter of days. Refund years are processed normally (usually 10–14 business days each), and any net debt is rolled straight into a payment plan before interest gets a chance to bite.
The deduction advantage of doing it properly
ATO pre-fill gives us your income, but only you (with our prompting) supply deductions - work-related expenses, vehicle use, home office, donations, income protection insurance. Across multiple years, properly claimed deductions routinely change outcomes by materially compared with the bare default-assessment-style numbers.
