Overdue tax help

Behind on Tax? Start Here.

People fall behind on tax for ordinary reasons: illness, a business that got busy, a separation, a bookkeeper who left mid-year, a bad year nobody wanted to look at, or one missed return that quietly turned into six. Almost none of it is dramatic, and almost all of it is fixable.

Being several years behind is not the end of the road. There is no point at which an overdue return becomes too old to lodge, penalties can be remitted, refunds in old years are not forfeited simply because the return is late, and ATO debt can usually be put onto an arrangement once the real balance is known. What matters is the order: bring the lodgements up to date first, establish the actual figure, then deal with penalties and payment. This page is the map - use it to find the situation closest to yours.

What are you behind on?

Each of these is a full explanation of how that particular backlog gets fixed - what the ATO already knows, what we need from you, and what it costs.

Overdue individual tax returns

Salary and wage years that were never lodged. Most of the income is already in ATO prefill, so the work is deductions, offsets and getting each year filed in order.

Overdue sole trader tax returns

ABN income with incomplete books. We rebuild business income and expenses from bank data, then lodge each year with the business schedule completed properly.

Overdue company tax returns

Company returns and financial statements brought current, including dormant companies and years where the accounts were never finalised.

Overdue BAS and GST

Quarters or years of unlodged activity statements, backdated GST registration, and the four-year limit that can quietly cost you input tax credits.

ATO debt and payment plans

Once the real balance is known, we ask for a payment arrangement you can actually sustain and request remission of interest where the facts support it.

Director penalty notices

A DPN has a strict 21-day window, and lockdown notices behave very differently to non-lockdown ones. This page explains which one you have and what to do first.

Late tax returns for tradies

Subbies and trades reported through TPRS. The ATO already has much of your income; we get the deductions and the outstanding years right.

Failure to lodge penalties and remission

Estimate failure to lodge penalties and general interest charge before you commit. One penalty unit is currently $364.

Missing records and old accounts

No receipts, closed bank accounts, a bookkeeper who disappeared. Reconstruction on a reasonable, documented basis is normal catch-up work, not a blocker.

Multiple years overdue

Five years, ten years, or a backlog you have stopped counting. Years are lodged oldest to newest so losses and carried-forward amounts flow through correctly.

The questions people ask first

How far behind are you?

It does not change whether we can help, only how the work is sequenced. One or two years is usually straightforward. Five or more years means we work oldest to newest so carried-forward losses, offsets and prior-year balances flow through in the right order. There is no cut-off point where a backlog becomes too old to bring up to date, and there is no limit on the number of years we can lodge in one engagement.

What happens when you contact us?

You complete a short confidential form. A registered tax professional reviews it and replies by text within one business day with what we think is outstanding, what we need from you and a fixed fee. No phone call is required at any point. If you would rather talk it through, you can book a free 15-minute call, but it is optional.

What if I don't have my records?

That is the normal starting position on a multi-year catch-up. Once you nominate us as your tax agent we can see every outstanding year and the ATO prefill data, which covers most salary and wage income, interest, dividends and government payments. The gaps are filled from bank and card statements, super fund records, agent summaries and anything you still hold. Where a deduction cannot be reasonably supported, we leave it out.

What happens with penalties?

Penalties may increase every 28 days, up to the applicable cap for each overdue document. One penalty unit is currently $364, and the standard maximum for an individual is five units, or $1,820 per overdue document. For failures occurring on or after 1 July 2026, one Commonwealth penalty unit is $364. Earlier failures may be calculated using the penalty-unit value applicable at that time. Failure to lodge penalties are remittable. We request remission as part of the engagement, and the ATO is generally more receptive once every outstanding year has been voluntarily brought up to date, but the decision always rests with the ATO.

What if I owe the ATO?

The sequence matters: lodge first, then deal with the debt. Until the outstanding years are lodged, nobody knows the real balance, and the ATO will not usually settle a durable payment arrangement over an unknown figure. Once the returns are in, we work with the actual number - a payment plan, a request for remission of general interest charge where the circumstances support it, or both.

How long will it take?

Once we have all required records, straightforward catch-ups are typically prepared and lodged within around 5 business days. Larger multi-year or complex matters generally take longer - often around 2-3 weeks. ATO processing time sits on top of that and is outside our control. Refunds across several back years are often manually reviewed before they are released, so allow extra time where multiple years are lodged at once.

What does it cost?

Fixed fees, quoted in writing before any work starts. Individual and sole trader years are from $699 +GST per income year, and company work is from $1,599 +GST per annum, with discounts when several years are caught up together. Fees are generally payable upfront. Approved payment arrangements may be available for qualifying multi-year engagements. Fee-from-refund may be available for eligible individual refund cases.

More detail on any of this is in our overdue tax FAQs and in how the catch-up process works.

Real anonymised catch-ups, including what was outstanding, what we did and how it finished - a carpenter over the GST threshold, a rideshare driver registered from day one, and a freelance designer with three income streams and no records.
