What to Do When the ATO Requests Records You've Lost

Quick answer: If the ATO has requested records you no longer have, don't ignore the request or wait until you've found everything. Read the request carefully to confirm exactly what's needed and by when, contact the ATO or your bank to reconstruct missing records (bank statements can typically be reissued even years later), and consider asking for a short extension if you need more time. Most records can be rebuilt — what matters most is responding on time, even if that response explains you're still gathering documents.

Getting a letter or myGov notification from the ATO asking you to produce records is unsettling, especially if you know straight away that some of what they're asking for no longer exists in an easy-to-find form. The good news: this happens constantly, and it's almost always recoverable. Here's exactly what to do.

This is one piece of a bigger picture — see our full guide to reconstructing financial records for the ATO if you're rebuilding more than just what's in this specific request.

First: understand what kind of request you've actually received

Not every ATO contact is the same, and the right response depends on which one you've got:

• A simple information request — the ATO is asking for specific documents to support something already lodged (a deduction, a BAS figure, income reported). Usually the lowest-stakes version.
• A formal audit or review notice — a broader examination of a period or specific claims, with a defined scope and timeframe.
• A pre-fill discrepancy notice — the ATO's own data (from banks, employers, or other sources) doesn't match what you reported, and they want an explanation.

Check the letter or notice for the specific wording, the period covered, and the response deadline. This determines how much time pressure you're actually under — it's usually more than people assume, and extensions are common (see below).

Step-by-step: responding when you're missing records

Step 1: Read the request closely before doing anything else

Note exactly what's being asked for, which financial year(s) or BAS period(s) it covers, and the actual due date. A vague sense of "the ATO wants my records" leads to either overreacting or gathering the wrong things. Most requests are narrower than they first appear.

Step 2: Take stock of what you actually still have

Before assuming records are gone, check the obvious places: accounting software (Xero, QuickBooks, MYOB), email confirmations, your accountant or bookkeeper's files if you've used one, and cloud storage. It's common to discover you have more than you thought once you actually look.

Step 3: Reconstruct what's genuinely missing, starting with your bank

For anything you can't locate, your bank is almost always your fastest path back to accurate records — banks are required to retain transaction history for several years, and most can reissue statements through online banking or on request, even for older or closed accounts. Once you have the statements:

• Convert PDF statements into structured transaction data — a PDF can't be filtered or totalled, so this is the necessary first step before you can reconcile anything against what you reported
• Reconcile the reconstructed data against your original lodgement — matching transactions against income, expenses, or GST figures as relevant to the request

This is the same core process used to fix a missed or incorrect BAS — if the ATO's request relates to a BAS period specifically, that guide walks through the reconciliation step in more detail.

Step 4: Decide whether you need professional help

If the request is a simple information request for a small number of documents, many people handle it themselves. If it's a formal audit, covers multiple years, or involves discrepancies you don't fully understand, a registered tax agent or accountant is worth engaging before you respond — not after. They can also often communicate directly with the ATO on your behalf, which takes the pressure off you to get every response perfectly worded.

Step 5: Contact the ATO if you need more time

If you genuinely can't meet the deadline — a bank is taking longer than expected to reissue statements, for example — contact the ATO before the due date, not after. Requesting an extension is routine and generally well received; going silent past a deadline is what actually causes escalation.

Step 6: Respond with what you have, clearly organized

You don't need every record perfectly reconstructed before you respond — a partial response that clearly explains what's included, what's still being gathered, and your expected timeline is far better than silence. Organize what you submit by period and by the specific item requested, so it's easy for the ATO to match against their request.

What happens if you genuinely can't produce a record

Sometimes a record is truly unrecoverable — a long-closed account, a business that no longer exists, a cash transaction with no paper trail. In these cases, be upfront about it rather than guessing or estimating without saying so. The ATO has processes for reasonable estimates and alternative evidence (invoices, contracts, third-party confirmations) when original records genuinely can't be produced — but only if you're transparent about the gap rather than trying to paper over it.

FAQ

How long does the ATO require me to keep records for? Generally five years from when you prepared or obtained the record, or from when the relevant transaction or activity is completed — whichever is later. This is also roughly the window in which an ATO request for older records is most likely.

What if I can't get bank statements far enough back? Contact your bank directly — most can go back further than what's available in standard online banking, though it may take longer and occasionally involve a fee for archived records. Start this as early as possible once you know you need historical statements.

Will responding late or incompletely trigger a bigger audit? Not automatically — but going silent past a deadline without any communication is far more likely to escalate things than a late or partial response where you've explained the delay. Contacting the ATO proactively is almost always viewed better than not responding at all.

Can I use bank statements alone to reconstruct everything the ATO is asking for? Bank statements reconstruct your transaction history well, but some requests (like specific deduction substantiation) need supporting documents beyond just the bank record — invoices, receipts, or contracts. Bank data is usually the fastest starting point, not necessarily the complete answer on its own.

Reconstructing records for an ATO request almost always starts with bank statements — and turning PDF statements into usable data is the slowest part of doing that by hand. Data River converts PDF bank statements into clean, structured data, so you can spend your time responding to the ATO instead of retyping transactions.
