How long to keep business records in Australia

If you run a business and you are trying to work out when you can safely throw records away, the practical answer depends on which rules apply to you. For most business records, business.gov.au states you need to keep them for 5 years. If your business is a company, ASIC states financial records must be kept for at least 7 years. Where both apply, the longer period governs the records that fall under both sets of obligations.

This guide explains what each official source actually says, how to apply the two timeframes without keeping two separate filing systems, and what you should verify for your own circumstances before deleting anything.

The two retention periods that matter

The ATO page makes the point that different regulators can impose different expectations. It gives the example that ASIC requires companies to keep records for 7 years. That is why the structure of your business changes the answer, not the type of document itself.

What the ATO expects from your records

The Australian Taxation Office states that you are legally required to keep records of all transactions relating to your tax, superannuation and registration affairs. Importantly, this obligation is not limited to the period in which you are actively trading. The ATO describes it as applying as you start, run, sell, change or close your business.

That framing matters for two reasons.

First, records created before you registered, while setting up, or during a sale or wind-down are part of the same obligation. A common mistake is treating pre-registration setup costs or post-sale paperwork as outside the record-keeping net.

Second, the ATO says its overview covers "5 record-keeping rules" that apply to most records your business is required to keep to meet tax, super and registration obligations. The existence of a defined set of rules is the reason to check the ATO's own summary rather than relying on a single remembered number.

The ATO also states, via business.gov.au, that you need to show the ATO your records if they ask for them. Retention is therefore not only about duration; it is about being able to produce the records in a usable form when requested.

Companies: the 7-year rule and the officeholder's duty

ASIC states that companies must keep certain records, that records help in keeping track of the company's business and meeting ASIC's lodgement requirements, and that companies must keep financial records for at least 7 years. ASIC also states that the types of records a company must keep are determined by law.

ASIC places responsibility clearly on people, not just entities. As a company officeholder, ASIC says you must understand and ensure your company meets its record-keeping obligations, and that your company must keep up-to-date financial records.

Two practical consequences follow from this:

• "Keep" implies current and complete, not merely old and stored. ASIC refers to up-to-date financial records, so a file that is seven years old but incomplete was not adequate at any point.
• The duty sits with officeholders, so it does not transfer to an accountant, bookkeeper or software provider by default. Outsourcing the work does not outsource the obligation.

How to apply both timeframes in practice

You do not need to decide between the 5-year and 7-year periods for every document individually. A workable approach:

1. Confirm your structure. Sole trader, partnership, trust and company obligations differ, and the company obligation is the one ASIC describes as at least 7 years for financial records.
2. Set your default retention to the longest period that applies to your structure. For a company, that means financial records are retained for at least 7 years under ASIC's guidance.
3. Treat tax, super and registration records as a separate category that you keep in line with the applicable ATO rules, rather than assuming the general 5-year figure covers everything.
4. Keep records that relate to starting, changing, selling or closing the business, not only ordinary trading records.
5. Make sure you can retrieve records. The ATO's position, as published by business.gov.au, is that you need to show your records if asked.

Because the ATO frames the obligation as covering the full life of the business, the safest practical assumption is that the clock runs from the transaction or event the record relates to, not from the date you happen to file it. Confirm the exact start point with the ATO or your registered tax agent before relying on it to destroy records.

Digital records and the ATO's direction of travel

business.gov.au states that the ATO recommends businesses use digital record keeping if possible, and that the ATO is moving towards digital records. business.gov.au also points to a free ATO tool that lets you check which records your business needs to keep and how well you are keeping them.

The practical reading: digital is the recommended default rather than an optional upgrade. Scanning paper records, keeping a consistent naming and backup approach, and making sure a record can be produced on request all support the ATO's stated requirement to show records when asked.

Checklist before you delete anything

• Have you identified whether your business is a company, and applied ASIC's at-least-7-years guidance to financial records?
• Have you separated tax, super and registration records and applied the applicable ATO rules to them?
• Do your records cover the full business lifecycle — start, run, sell, change, close — as the ATO describes?
• Can you produce records if the ATO asks for them?
• Are your financial records up to date, as ASIC requires, not just retained?
• Have you run the free ATO record-keeping tool referenced by business.gov.au to check coverage?
• Is your storage approach digital where possible, consistent with the ATO's stated preference?

Questions to verify for your situation

The official sources above give the headline periods, but several details are worth confirming directly with the ATO, ASIC or your adviser:

• The exact point at which each retention period starts for a given record type.
• Which records count as "financial records" for ASIC purposes as opposed to other company records, since ASIC states the required types are determined by law.
• Whether any additional obligations apply to your industry, to employment and super records, or to records held on behalf of others.
• Whether records must be kept in a particular form, language or location to satisfy a request from the ATO.
• What applies after a business is sold or deregistered, including who holds the records.

This guide does not set out penalties or enforcement outcomes. The ATO page states you can learn who is accountable for keeping business records and what to expect if you do not meet obligations — read that section on the ATO site directly if consequences are your concern.

Your next step

Start with the free ATO tool referenced by business.gov.au, which is designed to show which records your business needs to keep and how well you are keeping them. Use its output to set one default retention period per record category, then confirm the company position against ASIC's at-least-7-years guidance if you operate through a company. Review your approach again whenever you change structure, sell, or close the business, because the ATO's obligation is described as running across all of those events.
