How it works

A senior second analysis,
on every return.

No new software to learn and nothing to rip out. Tony.Online sits alongside the way you already work — three simple steps from return to sign-off.

1

Drop in the return

Send Tony.Online the return and your working papers — individual, trust, company, partnership or SMSF.

2

Tony.Online reads every line

Every item, label and field is checked against your workings, the return instructions and current ATO guidance.

3

You approve & sign off

You get a clear Certificate of Taxation Analysis — what's traced, what to check, what's flagged. You sign off.

The output

Every line, resolved.

A clear, item-by-item read on the return — ready for the file.

The analysis

Three outcomes, every line.

Tony.Online works the way your best reviewer would — methodical, grounded and tireless. Every line lands in one of three places, so nothing is left ambiguous.

No action needed

Traced & consistent

The figure ties back to your working papers, the return instructions and current ATO guidance. It's evidenced, consistent, and ready for the file.

Worth a second look

Check needed

A judgment call or a value that deserves a human eye — a threshold, an apportionment, a classification. Tony.Online surfaces it with context so you can confirm the treatment before you sign.

Fix before lodging

Flagged to check

A likely error, inconsistency or ATO-risk item. Tony.Online explains what it found and why it matters — so you can correct it before lodgement, not after the ATO does.

The deliverable

What lands on the file.

Every review produces a clear Certificate of Taxation Analysis — a documented, line-by-line read you can stand behind.

  • Every label rated Green, Orange or Red.
  • The reasoning and ATO source for each finding.
  • An entity-by-entity summary and overall rating.
  • Evidence of reasonable care — ready for the file.
Reasonable care, documented. Support for your file and your client conversations.
