Penalty Units Increased From 1 July 2026. What It Costs You

From 1 July 2026, the value of a Commonwealth penalty unit rose from $330 to $364. It sounds like a small administrative tweak, but it flows straight through to a wide range of ATO penalties, quietly pushing up the cost of getting things wrong.

A penalty unit is just the method used under Commonwealth law to work out many fines and administrative penalties. Instead of a fixed dollar figure, legislation often refers to a number of penalty units, so when the unit value goes up, every penalty built on it goes up too. The new rate applies to breaches from 1 July 2026 onward, anything before that date is still assessed at the old rate.

Where you'll feel it

A few areas are worth knowing about, since they're the ones businesses and individuals are most likely to run into.

Late lodgement. This is the most common one. The base penalty is generally one unit for every 28 days (or part of 28 days) a document is outstanding, up to a maximum of five units. For a small entity, that maximum has moved from $1,650 to $1,820. Medium and large entities face higher penalties again, and significant global entities more again.

False or misleading statements. Where incorrect information is provided to the ATO and there's no tax shortfall, base penalties of 20, 40 or 60 units can apply depending on the circumstances. At the new rate, that's $7,280, $14,560 or $21,840, before any reductions or increases are applied.

SMSF trustees. Several SMSF administrative penalties are also calculated using penalty units. A breach that previously carried a $19,800 penalty (60 units) now sits at $21,840.

These SMSF penalties are generally imposed on each individual trustee, not the fund itself. Where a fund has multiple trustees, that adds up fast, and the penalty can't be paid out of the fund's own assets.

Record-keeping requirements, tax invoice obligations and some superannuation guarantee penalties can also be affected by the higher rate.

Why it's worth paying attention to

For most people, these penalties are avoidable. Late lodgements, patchy records and incorrect information remain the most common reasons businesses and individuals end up with an ATO penalty in the first place. On their own, a few extra dollars per penalty unit might not seem like much, but it adds up quickly if there's more than one outstanding obligation, or if compliance issues keep repeating.

It's also worth remembering that ATO penalties generally aren't tax deductible, so they come straight out of after-tax income.

The ATO will often consider remitting penalties where there's genuine mitigating circumstance, reasonable care has been taken, or a voluntary disclosure is made before the ATO identifies the issue itself. Getting ahead of a problem almost always leads to a better outcome than waiting for the ATO to come to you.

A few practical habits that help

None of this requires anything dramatic, just a bit of consistency:

• Lodge on time, and get information together well before deadlines so there's room to prepare things properly
• Keep accurate, current records, which makes it far easier to lodge correctly and back up your position if anything is questioned
• Review compliance regularly, particularly for businesses and SMSFs, so small issues get caught before they become expensive ones
• Speak up early if something's fallen behind, since there are usually more options available before the ATO gets involved than after

Businesses that already have solid bookkeeping habits in place tend to find this kind of thing much less stressful. When records are current and cash flow is easy to see at a glance, whether that's through a simple spreadsheet or ongoing Xero bookkeeping, lodgements tend to happen on time almost as a matter of course.

The bigger picture

The rise in penalty units is really just a reminder that the cost of non-compliance keeps climbing. The penalties themselves are meant to encourage timely, accurate reporting, but they're also a nudge toward better habits around record keeping and proactive tax management generally.

If you've got outstanding lodgements, record-keeping gaps, or any other compliance matter on your mind, it's worth sorting out sooner rather than later. Get in touch with a Trekk Advisory advisor to talk through where things stand.
