What is gst review & notice support?
An ATO review or data-matching letter answered with the reconciliation that actually resolves it — prepared for your agent’s response.
A GST letter from the ATO rarely opens with the word 'audit'. Most start as a data-matching mismatch — the GST credits claimed on a BAS don't line up with what a supplier reported, or a refund pattern trips an automated risk filter — and arrive as a request for information with a response window set in the letter, commonly 14 to 28 days. What the letter is actually asking for determines everything that follows: an information request wants specific transactions explained; a formal audit wants the full period reconstructed; an amended assessment means the ATO has already decided something and the clock on a 60-day objection window has started.
The single worst move at this stage is answering fast. Early submissions can shape and limit what the ATO finds later — a phone call made to 'sort it out quickly' before anyone has pulled the source documents can hand the case officer a fact that then has to be lived with for the rest of the review. The ATO can reach back up to four years on a GST audit, so the first job is never the response — it's reconstructing the period under review against bank statements, tax invoices, contracts and the GST calculation workpapers that produced the lodged BAS figures.

GST review & notice support in Australia
An information request is not the same document as a formal audit, and the response differs
The ATO's opening letter usually names itself — a data-matching or information request asks for specific transactions to be explained, typically inside a 14–28 day window set in the letter; a formal audit reconstructs a full period and runs on a longer, case-managed timeline; an amended or default assessment means a decision has already been made and starts a 60-day clock to lodge a formal objection if the client disagrees. We read the letter for which of these it is before building anything, because the pack an information request needs is narrower than the pack a full audit needs, and treating one as the other wastes the response window.
Don't volunteer information before the source documents are reconstructed
Anything said to the ATO before the underlying period has been reconciled can narrow the agent's room to argue later — an early, well-meant explanation on a phone call becomes a fact the case officer holds the client to. We build the reconciliation first and hand it to your registered agent to decide what, if anything, gets said before that pack exists.
Remission of penalties or interest cannot be requested until outstanding BAS lodgments are current
Failure-to-lodge penalty remission and general interest charge remission both require every overdue BAS or IAS to be lodged first — the ATO will not process a remission request against an open lodgment gap. Since January 2026, more complex remission cases go through a formal written application rather than a phone resolution. We check the lodgment history against the letter before your agent submits anything, so the remission request isn't rejected on a technicality that had nothing to do with the substance of the case.
A 60-day objection window starts on the date of the assessment or decision notice, not the date it was opened
If the ATO issues an amended or default assessment the client disagrees with, a formal objection generally has to be lodged within 60 days of the notice date (longer windows apply to some categories). We flag the notice date as soon as a letter comes in and build the evidence pack against that deadline, because a missed 60-day window is one of the harder things to walk back once it has passed.
What your registered BAS or tax agent receives from us
- A period reconstruction matched to the ATO letter's stated scope — every transaction inside the named period and label, traced to its source document.
- A GST tax-code exception log for the disputed transactions, showing the code applied, the document it was matched against, and any inconsistency found.
- A reconciliation of GST collected and GST credits claimed for the period against the figures actually lodged on the relevant BAS.
- A lodgment-history check confirming which BAS or IAS periods are current and which are outstanding, ahead of any remission request.
- A dated timeline of the ATO correspondence — letter received, response window, any extension sought — so your agent can track the case against its own deadlines.
- Source-document copies (tax invoices, bank statements, contracts) indexed to the specific transactions the ATO letter references, ready for your agent to submit or hold.
