Tax Record Keeping in Australia -- What to Keep, How Long, and Why It Matters

Good tax records are the foundation of every legitimate deduction. Without receipts and documentation, even valid work-related expenses cannot be claimed -- and if the ATO audits your return, undocumented claims must be reversed with interest and penalties. GoTax is an ATO-registered online tax service that flags record-keeping gaps before your return is lodged. The free Deduction Grabber app makes records effortless throughout the year. Fixed pricing from $0. Done online in minutes.

What Records You Need for Your Tax Return

The ATO's record-keeping requirements are specific. For each deduction you claim, you need documentary evidence -- typically a receipt, invoice, or statement -- showing the amount, date, supplier, and nature of the expense. Bank statements alone are not sufficient for most work-related claims.

The table below summarises the key record types, what to keep, and how long the ATO requires you to hold them.

The five-year retention period starts from the date you lodge your return -- not the end of the financial year. Records kept for purchases of depreciable assets must be held for the full depreciation period plus five years. See the ATO's record-keeping guide for individuals for the complete ATO position.

How to Keep Your Records -- Four Practical Methods

The ATO accepts digital records, provided they are a true and clear reproduction of the original and can be retrieved if required. Paper records are also acceptable. Choose the method that you will actually use consistently throughout the year -- the best system is the one you stick to.

Five Record-Keeping Mistakes That Cost Australians Money Every Year

1. Waiting until June to start gathering receipts. Receipts fade, apps get deleted, and email inboxes fill up. By the time July arrives, many people have lost documentation for months of legitimate deductions. The Deduction Grabber app solves this by capturing receipts at the point of purchase -- taking thirty seconds now prevents a missed deduction worth hundreds of dollars later.

2. Keeping bank statements instead of invoices. A bank statement showing a transaction is not the same as a tax invoice. For most work-related claims, the ATO requires a receipt or invoice showing the supplier's name and ABN, the date, the amount, and what was purchased. If you only have a bank entry, that deduction is at risk in an audit.

3. No home office diary for the WFH fixed rate. You do not need to record every single WFH hour -- but you must have a representative four-week diary that reflects your typical WFH pattern during the income year. Many people claim the fixed rate (70 cents per hour) without keeping any diary at all. If audited, the claim must be removed entirely. Four weeks of records protects the whole year.

4. Losing the car logbook. A valid ATO logbook (minimum 12 continuous weeks, kept within the last five years) is required for the logbook method of vehicle claims -- which typically produces a larger deduction than the cents-per-kilometre method. Logbooks must show date, destination, purpose, odometer start and finish for each work trip. Many taxpayers use the cents-per-kilometre method simply because they never got around to keeping a logbook.

5. Throwing out receipts for items over $300. A laptop, tool, or piece of equipment costing more than $300 cannot be claimed in full in the year of purchase -- it must be depreciated over its effective life. That means you need the original receipt showing the purchase date and price for as long as the depreciation schedule runs, plus five years after lodgement. Losing the receipt doesn't make the asset disappear from your tax return -- it just makes it impossible to substantiate.

Frequently Asked Questions

How long does the ATO require me to keep tax records?

The ATO requires you to keep records for five years from the date you lodge your tax return. For depreciating assets, records must be kept for the entire depreciation period plus five years. If you carry forward a tax loss, records relating to that loss must be kept for five years from the year the loss is fully deducted. In practice, a rolling seven-year retention policy covers all scenarios without needing to track different periods for different records.

Do I need original paper receipts, or are digital copies acceptable?

Digital copies are acceptable to the ATO, provided they are a true and clear reproduction of the original document and can be readily accessed if requested. A photo taken on your phone, a PDF email receipt, or a scan are all acceptable. The key requirement is that the digital copy is legible, complete, and not edited. The Deduction Grabber app produces ATO-compliant digital records automatically.

What records do I need for a home office deduction?

For the fixed rate method (70 cents per hour), you need a representative four-week diary showing the hours you actually worked from home during that period. The diary must cover a typical week -- not a holiday period or unusually heavy or light WFH period. For the actual cost method, you need receipts for each expense (electricity, internet, gas) and a floor plan or room measurements to calculate the work-related proportion of your home. Equipment and furniture in the home office are claimed separately via depreciation.

What records do I need for car and vehicle deductions?

Under the logbook method, you need a valid ATO logbook covering at least 12 continuous weeks, showing the date, destination, purpose, and odometer readings for each work trip. You also need odometer readings at 1 July and 30 June each year. A logbook is valid for five years if your work travel pattern does not change significantly. Under the cents-per-kilometre method, you do not need a logbook, but you must have a record of the total work kilometres travelled during the year -- a diary, calendar entries, or travel records noting each trip.

What happens if the ATO audits my return and I don't have records?

If the ATO audits your return and you cannot produce records to substantiate a deduction, that deduction will be disallowed. You will be required to repay the tax saved, plus interest calculated from the original due date. If the ATO considers the claim was reckless or intentional, a penalty of 25% to 75% of the shortfall may also apply. The ATO can audit returns up to two years from the date of assessment for most individual taxpayers -- or four years if it suspects tax avoidance. Good records are the only complete protection.

Can I use the GoTax Deduction Grabber app instead of paper receipts?

Yes. The ATO accepts digital records, including photos of receipts captured via a dedicated app, provided they are a clear and complete reproduction of the original. The Deduction Grabber app is designed to meet ATO requirements -- it captures the supplier, date, amount, and category of each expense, and includes an ATO-compliant digital logbook for vehicle kilometres. Download it free from the Deduction Grabber website, Google Play Store, or the App Store.  Or scan the QR code below.

How do I organise records for multiple income sources?

If you have income from multiple sources -- employment, rental property, investments, or a side business -- keep records for each source separately. For rental properties, keep all expense receipts (repairs, rates, insurance, agent fees, loan interest statements) in a dedicated folder for each property. For share investments, keep contract notes for every purchase and sale for the life of the investment plus five years. For employment, keep PAYG summaries, work-related expense receipts, and any salary sacrifice documentation. GoTax handles returns with multiple income streams and guides you through each category.
