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.

Questions worth asking before you start

Who actually does the work — a person or an AI tool?

A named person on our team owns your file and reviews everything that leaves it. Software does a real share of the grinding underneath it — coding, matching, flagging the obvious gaps — but nothing regulated happens without a person’s judgement, and nothing here is signed or filed by an algorithm.

Who can legally lodge this?

Your registered agent responds to the ATO; CapEasy builds the reconciliation and evidence pack behind the response.

Which software do you work in?

Whatever you already run. Most commonly QuickBooks, Xero, NetSuite, Sage, Zoho Books and a handful of others — we work inside your system rather than moving you onto one of our own.

How does this actually start?

A short, free read-only look at what you already have, and a written note on what we found. A scoping call decides the size of the engagement — nothing here commits you to anything.

What does it cost?

There is no published price for gst review & notice support — it depends on volume, how many entities are involved, and how far behind the books are. We quote after the read-only review, which is free.

How does this fit with the rest of gst & bas?

GST review & notice support sits inside gst & bas, alongside GST registration, BAS preparation, IAS preparation. Most clients end up buying the category as a whole rather than one leaf at a time, but starting narrow is fine.

We just got a letter from the ATO about our GST — what do we do first?

Read what kind of letter it is before responding to anything. An information request, a formal audit and an amended assessment each run on different clocks and need different responses. Send it to us and your registered agent straight away — we start reconstructing the period it covers while your agent reads it for what it's actually asking.

Will CapEasy respond to the ATO on our behalf?

No. Your registered BAS or tax agent responds to the ATO and deals with the case officer directly, under their own TPB registration. We build the reconciliation and evidence pack the response is built on — the source-document trail, the exception log, the period reconstruction — and hand it to your agent to use.

Why shouldn't we just call the ATO and explain what happened?

Because an early explanation, made before the underlying transactions have actually been reconstructed, can become a fact the case officer holds you to for the rest of the review. We build the reconciliation first specifically so your agent has something solid to respond from, rather than an off-the-cuff account that might not match what the documents show.

How far back can an ATO GST audit reach?

Commonly up to four years. That's why the response isn't just about the transaction the letter names — it's a full reconstruction of the relevant period, matched document by document, so nothing in the years behind the flagged transaction surfaces as a surprise later.

Can we request a penalty remission if we still have overdue BAS lodgments?

No — the ATO won't process a remission request for failure-to-lodge penalties or interest until every outstanding BAS is lodged and current. We check your lodgment history against the letter before your agent submits anything, so a remission request doesn't get rejected on a technicality.

What changed with remission requests from January 2026?

More complex remission cases now go through a formal written application rather than being resolved over the phone. Simple cases can still be sorted quickly; anything with real substance needs the application done properly, which is part of what we prepare.

How long do we have to object if we disagree with an ATO assessment?

Generally 60 days from the date on the assessment or decision notice, not the date you opened the letter. We log that date the moment a notice arrives and build the evidence pack against it, because that window is one of the harder ones to get back once it closes.

What happens if we disagree with the outcome of a formal objection?

The next step is the Administrative Review Tribunal or the Federal Court, which is a legal-practitioner matter, not a BAS or tax agent one. We track a case to that point and hand off to a qualified AU tax or legal practitioner rather than stretching the engagement past what your agent's registration covers.

What does the evidence pack actually contain?

A reconstruction of the transactions the ATO letter covers, each one matched to its source document and its GST tax code; a reconciliation of GST collected and credits claimed against what was actually lodged; an exception log flagging anything inconsistent; and a lodgment-history check. Your agent reviews it, decides what the response argues, and submits it as theirs.

Do you decide what our response to the ATO says?

No. We assemble and check the reconciliation and evidence behind the response. What the response actually says — what's conceded, what's argued, what's escalated — is your registered agent's call, made under their own professional judgment and TPB registration.

What if the reconstruction finds a transaction we genuinely can't substantiate?

We flag it in a running exposure note rather than leaving it for the ATO to find first. Your agent then decides how to handle that specific item in the response — that's a judgment call for them to make with full visibility, not something we paper over.
