How this usually works
A good ATO review help process starts with a fast scoping call and a check of the ATO letter, reference numbers and due dates. From there, the work typically runs in clear steps to reduce risk and keep communication clean.
- Scope and triage: Identify the tax type, periods, questions asked and any immediate lodgement or payment pressure.
- Authority and liaison: Ensure your registered agent is linked to your account to speak with the ATO and request time if needed.
- Evidence pack: Extract the general ledger, trial balance, bank statements, STP reports, invoices and working papers that support the queried items.
- Explanation: Prepare clear, reconciled explanations for variances (e.g., BAS vs income tax, GST refund positions, payroll and super records).
- Submission and follow‑up: Lodge the pack, respond to clarifications, and keep a log of what was provided and when.
- Closure: Seek written confirmation of “no further action” or manage amended assessments, payment plans, penalty remission or escalation to an ATO audit if required.
Australian context to keep in view
- Reviews often follow ATO data‑matching across banks, STP, TPAR, property, crypto and third‑party sources. Be ready to reconcile to external data.
- Registered tax/BAS agents can request realistic extensions and help with penalty remission by showing cooperation and strong records.
- Voluntary disclosure reduces penalties. If you find an error during prep, disclose it with evidence instead of waiting for the ATO to detect it.
- Recent client‑to‑agent linking rules mean you may need to link your business to your agent in Online services before they can act.
- If you disagree with an amended assessment, you can object. See ATO objection support for process and timelines.
What to compare before you commit
Scope
Confirm the provider will handle ATO liaison, document prep, reconciliations, written explanations, extensions, and follow‑up through to closure — not just advice.
Software fit
Experience with your stack (Xero, MYOB, QuickBooks, payroll and STP tools) matters. Ask how they extract, reconcile and evidence transactions — not just which software they use.
Turnaround and communication
Check response times, who speaks to the ATO, how updates are provided, and how urgent escalations are managed ahead of deadlines.
Commercial fit
Understand pricing (fixed fee vs hourly), likely ranges for simple vs complex reviews, what’s included, and any additional costs if the matter escalates to audit or objection.
Common triggers of an ATO review
- Large or unusual GST refunds or credits compared to prior periods or peers.
- Variance between BAS figures and annual income tax returns.
- STP or payroll anomalies, super underpayment, or PAYG withholding mismatches.
- Late, amended or inconsistent lodgements over multiple periods.
- Data‑matching discrepancies (bank, property, crypto, TPAR, foreign income).
- Related‑party loans, director drawings, or private use adjustments without support.
Being proactive — with reconciled ledgers, source documents and clear explanations — is the fastest path to a “no further action” outcome.
Documents to prepare
Prepare only what is requested, plus any supporting evidence that clarifies the position:
- General ledger and trial balance for the review period(s).
- Bank statements and bank reconciliation reports.
- Tax invoices and receipts for material sales and purchases.
- Payroll summaries, STP reports, PAYG and super records.
- BAS, IAS and lodged income tax returns, with workings for key adjustments.
- Contracts and calculations for related‑party transactions or private use.
Timeframes and outcomes
Simple reviews can close in a few weeks with a “no further action” note. More complex reviews may lead to clarifications, amended assessments, interest (GIC) and penalties. Good cooperation, strong documentation and voluntary disclosure can reduce penalties. If you disagree with the outcome, you can object within the set timeframe — see ATO objection support.
Costs: what ATO review help typically costs
- Simple, single‑issue reviews with tidy books: typically a fixed fee.
- Multi‑period or data‑heavy reviews: usually a fixed fee cap with hourly overages.
- Escalation to audit or objection: scoped separately due to expanded evidence and submissions.
To avoid surprises, ask for a written scope that covers ATO liaison, evidence prep, submission, follow‑ups and closure reporting.
Best next steps
Write down the exact outcome you want: a closed review, reduced penalties, a payment plan, or help preparing for a potential audit. Then shortlist providers who can show a clear plan from evidence gathering to closure.

Frequently asked questions
Is an ATO review the same as an audit?
No. An ATO review is a targeted check that may end with no further action, requests for clarification or adjustments. It can escalate to a full audit if issues remain unresolved.
What usually triggers an ATO review?
Large GST refunds, BAS vs income tax variances, STP or payroll anomalies, late or inconsistent lodgements, and data‑matching discrepancies (bank, property, crypto, TPAR) commonly trigger reviews.
What documents should I prepare?
General ledger, trial balance, bank statements, tax invoices, payroll/STP reports, BAS/IAS and tax return workings, plus explanations for material variances.
How long does an ATO review take?
Simple matters can close in 2–6 weeks. Complex reviews with multiple periods or data requests can run for months.
Can I get more time to respond?
Yes. You or your registered agent can request an extension, especially when gathering third‑party records or reconstructing data.
What happens if the ATO changes my assessment?
You may receive an amended assessment with interest and possible penalties. If you disagree, you can lodge an objection. Good cooperation and voluntary disclosure help with penalty remission.
