The Five-Year Rule

Australian tax law generally requires business records to be kept for five years from the date of the relevant transaction, or from when the tax return reporting it was lodged. Some records run longer — assets relevant to a future capital gains tax event need to be kept for five years from the date of the eventual sale or disposal, which can mean holding records for well over a decade.

What Actually Needs to Be Kept

  • Sales and income records — invoices issued, payment records, and anything substantiating reported income
  • Expense records — tax invoices and receipts for all claimed purchases and business expenses
  • Bank statements — for all accounts used in the business
  • Payroll and superannuation records — pay records, STP reports, super contribution evidence
  • Asset and depreciation records — purchase price, date acquired, and depreciation schedules
  • Vehicle logbooks — where vehicle expenses are claimed using the logbook method
A common misconception: a bank statement alone isn't sufficient substantiation for most expense claims. The ATO generally expects a supporting tax invoice or receipt showing what was actually purchased, not just that money left the account.

Digital Records Are Fully Acceptable

There's no requirement to keep paper originals. Digital records are entirely acceptable, provided they're a true and clear copy of the original document, accessible on request, and retained for the full required period. This is exactly why receipt-capture tools that photograph and store documents digitally have become standard practice — a faded paper receipt is far less reliable as a long-term record than a digital copy stored from day one.

What Happens When Records Aren't Adequate

Without proper substantiation, the ATO can disallow deductions or GST credits that were claimed — meaning a higher tax bill than originally reported, generally with penalties and interest added. In an audit situation specifically, inadequate records put the business in a weaker position: the ATO can form its own view of income and expenses, and the onus shifts to the business to prove that assessment is wrong, which is far harder to do without the original records.

A Practical System Beats a Perfect One

The businesses that struggle most with record-keeping aren't usually trying to hide anything — they simply don't have a system, so receipts get lost and bank statements alone end up doing the substantiation work, badly. A simple, consistent habit of capturing documents at the point of purchase, backed by a properly maintained Xero file, solves the vast majority of record-keeping risk without much ongoing effort.
