A missing receipt can be inconvenient. Missing records during an ATO review, a payroll dispute or a business sale can be far more costly. If you are asking how long keep business records, the practical answer is usually at least five years – but many Australian businesses need to keep particular records for seven years or longer.
The right retention period depends on the type of record, your business structure, whether you employ staff and whether a transaction may affect tax in a future year. A clear records-management process protects your compliance position and gives you reliable numbers for cash-flow, tax and growth decisions.
For most income tax, GST and PAYG obligations, the ATO requires businesses to keep records for five years. The five-year period generally starts from the date you prepared or obtained the record, or from when the relevant transaction or act was completed, whichever is later.
These records must explain all transactions and other acts relevant to your tax affairs. They need to be in English, or readily convertible to English, and kept in a form that can be accessed if the ATO asks to see them.
For a typical small business, this includes sales invoices, purchase invoices, receipts, bank statements, loan documents, expense claims, accounting reports, BAS working papers and copies of lodged tax returns. If you use cloud accounting software, the information can be stored digitally, provided it remains complete, accurate and accessible for the full retention period.
Five years is a minimum rule, not a signal to automatically delete everything once the date arrives. Before destroying records, consider whether they relate to an asset, an unresolved tax matter, a carried-forward loss or another obligation with a longer timeframe.
Different rules can overlap. Where two retention periods apply, use the longer period. That approach reduces the risk of disposing of documents that you later need for compliance, a workplace matter or due diligence.
Keep records supporting your income tax position and BAS reporting for at least five years. This includes tax invoices, receipts, supplier statements, sales records, bank feeds, GST calculations, adjustment notes and relevant contracts.
Good records do more than substantiate a deduction. They help confirm that GST has been reported correctly, support input tax credit claims and make BAS preparation much more straightforward. If a receipt is faded, incomplete or lost, a bank transaction alone may not always establish the business purpose or GST treatment.
Employers must generally keep employee records for seven years under workplace laws. This is separate from your ATO obligations and applies whether the employee is full-time, part-time or casual.
The records can include pay rates, hours worked, overtime, leave balances, deductions, superannuation contributions, payslips, termination details and written employment arrangements. Records must be accurate, readily accessible and kept confidential. You should also retain evidence supporting your Single Touch Payroll reporting and PAYG withholding position.
For many growing businesses, payroll is where a five-year filing habit creates unnecessary exposure. A seven-year retention policy for employee records is the safer operational standard.
If you operate through a company, the Corporations Act requires financial records to be kept for seven years after the relevant transactions are completed. Financial records should correctly record and explain transactions, financial position and performance.
This can include your general ledger, journals, accounts payable and receivable reports, financial statements, bank reconciliations, loan schedules and supporting source documents. Seven years is also a practical benchmark for company records because it aligns with key payroll and corporate obligations.
Employers need records showing how they calculated super guarantee obligations, when contributions were made and the amounts paid. These records generally need to be retained for five years.
However, keep documentation for longer where it supports employee entitlements, payroll records or an unresolved issue. Evidence of super payments, such as fund receipts and clearing house confirmations, should be easy to match to each employee and pay period. Late or incorrectly calculated super can lead to the Super Guarantee Charge, so clear records matter.
Assets require a longer view. Keep purchase contracts, settlement statements, improvement costs, depreciation schedules, loan documents and disposal records for as long as you own the asset, then for five years after you sell, transfer or otherwise dispose of it.
This applies to assets such as business premises, vehicles, machinery, shares and business goodwill. The documents may be needed to calculate a capital gain or capital loss years after the original purchase. Deleting them after five years from purchase can make a future capital gains tax calculation difficult and potentially more expensive.
If your business carries forward tax losses, has unpaid tax disputes, receives amended assessments or is subject to an ATO review, retain relevant documents beyond the usual period. Records should remain available until the matter is finalised and the applicable retention period has passed.
The same principle applies to contracts with ongoing obligations, leases, shareholder arrangements and financing documents. Their value is not limited to tax compliance – they may be essential if there is a commercial disagreement or a future sale of the business.
A retention policy should be simple enough that it is followed every week, not just when year-end is approaching. Start by keeping source documents attached to transactions in your accounting software. This creates an audit trail from the bank transaction through to the invoice, receipt or contract that explains it.
Use clear folder names and consistent categories for documents outside your accounting platform. For example, separate payroll, superannuation, BAS, income tax, contracts, asset purchases and finance documents. Restrict access to payroll and personal information, and ensure former staff cannot access records after they leave.
Digital storage is usually more efficient than paper, but it needs controls. Back up critical data, use multi-factor authentication, review user access regularly and make sure exported reports can be read if you change accounting software. A cloud file is only useful if you can locate it, verify it and produce it when required.
If you scan paper receipts, check that the image is clear and captures all relevant details. For tax purposes, electronic copies can be acceptable, but a blurry photo without a supplier name, date, amount or description may not support your claim.
Only destroy records after checking the longest applicable retention period. Confirm that there is no audit, objection, dispute, asset ownership period, carried-forward loss or employment issue that requires them to be kept longer.
For digital files, permanent deletion should follow your business privacy and cyber-security procedures. For paper files, use secure destruction rather than placing financial or employee information in ordinary rubbish or recycling. Sensitive records can expose your business and staff to fraud if they are discarded carelessly.
A yearly review after finalising your tax return is a sensible time to identify records that are approaching their disposal date. Keep a simple register showing the record category, financial year, required retention date and storage location. This removes guesswork when staff change or the business expands.
Keeping records for the correct period is not simply an administrative requirement. Well-organised financial information helps you identify overdue debtors, understand margins, monitor payroll costs and make decisions from current facts rather than assumptions.
If your records are scattered across inboxes, devices and paper folders, bringing them into order now is usually easier than reconstructing them under pressure. Everest Accounting helps businesses build accurate, compliant record-keeping processes that support both ATO obligations and clearer business decisions. A disciplined system today gives you more confidence whenever an opportunity, deadline or question arises.
