Are digital copies of receipts acceptable to the ATO?

Yes, provided they're true and clear reproductions of the original and you can produce them if asked.

What happens if I cannot produce records for a deduction?

The ATO can deny deductions or GST credits that can't be substantiated. Missing records also slow bookkeeping down and push up accounting costs long before any review ever happens, which is the part people tend to forget.

Do records need to be kept in Australia or in English?

In English, or easily convertible, and accessible if the ATO asks.

Business record keeping: what to keep and for how long

Jamee White, CPA26 July 20265 min read

If in doubt, keep it. Five years is the floor for how long Australian businesses generally need to keep tax records, in English or easily convertible, available the moment the ATO asks: income, expenses, GST, payroll, assets, all of it. Some employment records need holding longer under workplace law, so five years is a starting point rather than a universal answer, and it's rarely the interesting bit. What's actually interesting is what to keep, in what form, and how to make the whole thing run itself instead of running you.

The core rule

Records generally need keeping for five years for tax purposes, usually counted from when the record was prepared or obtained, or when the relevant transaction or return was finalised, whichever is later. In practice, disputes, carried forward losses and depreciating assets can all stretch how long a record actually stays relevant. Treat five years as the minimum, and hold onto anything connected to an open matter until it's genuinely closed.

A few categories run on separate rules entirely. Employee records under workplace law carry their own retention periods, which can exceed the tax rule; check Fair Work guidance or ask your adviser. Company records under corporations law bring their own obligations too.

What to keep

Sales records: invoices issued, receipts, cash register or POS summaries
Purchase and expense records: supplier tax invoices, receipts, contracts
Banking records: statements for every business account, loan documents
GST records: tax invoices, adjustment notes, activity statement workings
Payroll records: pay runs, super contributions, PAYG withholding, employee details, timesheets
Asset records: purchase documents, depreciation schedules, disposal records, some needing to be kept well beyond five years from purchase
Stock records: stocktake workings and valuations
Year end records: financial statements, reconciliations, tax return workpapers

Paper or digital

Digital records are entirely acceptable, scans and photos of paper originals included, provided the copy is a true, clear reproduction and you can produce it on request. For most businesses that settles the question: capture everything digitally the moment it arrives, and stop wrestling shoeboxes.

The practical standard worth aiming for is every transaction in your accounting file carrying its source document attached. Modern platforms make this easy: email a supplier invoice to a capture address, or photograph a receipt, and the document lands against the transaction it supports. Five years of substantiation then exists as a by-product of ordinary bookkeeping, not a separate filing project someone has to remember to do at year end.

What poor records actually cost

The obvious risk is an ATO review where deductions or GST credits can't be substantiated and get denied. The quieter costs land earlier: bookkeeping takes longer when documents are missing, questions bounce back and forth between you and your bookkeeper, year end fees climb because the accountant's reconstructing history, and decisions get made on numbers nobody fully trusts. Good records are cheaper than bad ones every single year, not just the year of an audit.

Building a system that maintains itself

Pick one capture method per document type and make it a habit: supplier bills forwarded to the accounting inbox, receipts photographed at purchase, contracts saved to one drive location. Reconcile bank feeds weekly so missing documents get chased while the transaction's still fresh. Then leave retention to the software; cloud accounting platforms hold attached documents indefinitely, comfortably covering the five year requirement provided your subscription and backups stay current.

Where NextEra fits

Record keeping fails the moment it depends on willpower. NextEra's managed monthly bookkeeping bakes document capture and reconciliation into a fixed rhythm so substantiation builds up automatically, and our Strategic Finance Review includes a look at whether your current records would survive a review without a scramble.

Quick answers

Generally five years for tax purposes, though some records, certain employee files and documents for long-held assets or open disputes among them, need holding longer. Treat five years as the floor, not the ceiling.
