For most Australian businesses, the answer to how long to keep business tax records in Australia is at least five years, but the start date depends on the record. The Australian Taxation Office generally counts from when the record is prepared or obtained, or when the related transaction is completed, whichever is later. Some records need to be kept longer, especially those relating to assets, carried-forward losses or an ATO review.
It’s understandable to want to clear out old paperwork when it starts taking over your office. But the five-year mark isn’t always the right time to delete a file, and knowing which records matter can make staying organised much easier.
This guide covers the usual retention periods, which records to keep, and how digital storage, business assets and special circumstances can affect how long you retain them. You’ll have a clearer idea of what to keep and why as your business grows.
Key Takeaways
- Most business tax records need to be kept for five years, but the retention period can depend on when the record or related transaction was completed.
- Keep asset purchase and sale records for longer than routine tax documents, as the required period can extend beyond the time you own the asset.
- Digital records can reduce paper clutter, provided they remain clear, accessible and protected from damage or alteration.
- Company, payroll and superannuation records can have separate retention requirements, so sort them by record type rather than relying on one disposal date.
- Keep supporting documents such as invoices, bank records and BAS information organised so you can explain business transactions if required.
Digital record storage and access
Digital filing can make business receipts and financial records easier to organise and retrieve. Keep records complete, clear and accessible throughout the required retention period.
Keeping records in digital and paper formats
Digital and paper record keeping means retaining business documents either electronically or in physical form. Australian businesses can use digital records without keeping paper copies as well, unless a particular law or rule requires them.
The Australian Taxation Office accepts scanned paper records when they’re true, clear reproductions that meet record-keeping rules. If a scan meets these conditions, you don’t need to retain the paper original solely because it was the original receipt. A blurred or incomplete image, however, may not show enough information to support the transaction.
Protect paper and digital records from damage or alteration. Store paper receipts safely until you’ve captured them clearly. Keep electronic invoices in a format that preserves their details and allows you to retrieve them later. The Australian Taxation Office recommends digital record keeping where possible, which can make searching and organising records more straightforward.
Accessing digital tax records
Accessible digital records are records you can locate, read and produce when needed. This matters if the Australian Taxation Office requests business records or you need to explain an entry in a tax return.
Keep electronic records in English or in a form that can be easily converted to English. Store them in a format that can generate reports if required. A folder of image files can preserve receipts, while accounting software can help present transaction details. In either case, records must remain readable and usable.
Taxation Ruling TR 2018/2 addresses income tax record keeping and access for electronic records. Practice Statement Law Administration PSLA 2008/14 covers record keeping when businesses use commercial off-the-shelf software. Together, these references highlight that retaining a file is not enough if its information can’t be accessed or understood.
Plan for access throughout the full retention period, not just while you use a particular device or software account. Use a consistent filing structure, clear labels and backups for important documents. For example, file a supplier receipt alongside the transaction it supports, rather than leaving it in an unlabelled downloads folder.
Digital storage can simplify retrieval, but you still need to retain complete evidence. Before discarding paper, confirm each image is clear and includes the full document. Then ensure relevant financial records remain readable, protected and available for the applicable retention period.
Capital gains tax asset records
Business assets can stay on your books long after routine invoices are cleared. For capital gains tax (CGT), keep relevant records while you own each asset and for the required period after disposal. An asset file can therefore be among the longest-lived parts of your tax records.
Keep documents showing when you acquired an asset, what it cost, and when you sold or otherwise disposed of it. Purchase and sale contracts, invoices and transaction records can help document the asset’s history. Keep them together rather than relying on a single accounting software entry to explain the full picture.
For CGT assets, the general retention period is the ownership period plus 5 years after sale or other disposal. There’s also a rule for acquired or disposed CGT assets: retain records for 5 years after it’s certain no CGT event can happen. The relevant end date can therefore depend on the asset and its circumstances.
Consider an investment property bought in 2024 and sold in 2044. The example retention date is 2049, which means keeping its records for 25 years after purchase. A file marked only with the purchase year could be discarded too early if it doesn’t account for the later sale and retention period.
Depreciating assets have a separate timing detail. Keep their records for 5 years from the date of your last claim for decline in value. Generally, retain records for as long as you own the asset, then for another 5 years after selling or otherwise disposing of it. Keep the claim history with the asset file.
For example, a vehicle bought for A$40,000 in 2020, used for eight years, and sold in 2028 has a long record trail. The example requires purchase records through 2033, or 13 years after purchase. Recording the disposal date helps set the retention timetable for that asset.
For each asset, note its purchase date, disposal date and last decline-in-value claim. Keep supporting records in a consistent format, linking relevant expenses to the asset. If software stores the transaction details, preserve access to the supporting documents as well. This makes the asset’s history easier to understand later.
Superannuation records have their own retention rules, so keep them separate from asset records. Create distinct categories for assets, payroll and superannuation, each with its applicable retention date. If asset transactions are difficult to reconcile with your business records, accounting and advisory support can help organise them more clearly.
Company record-keeping requirements
Companies have corporate record-keeping duties in addition to ordinary tax obligations. Employee records and financial books may also have different retention periods.
Yes. Companies have additional corporate record requirements, while sole traders generally follow the business tax record rules. Trusts must also preserve important trust documents, including the trust deed.
Company financial records
Company financial records document transactions, financial position and performance. Complete records help a company prepare accurate financial statements and explain its accounting decisions.
Under the Corporations Act 2001, company records must be kept up to date and correctly track and explain transactions. They must also enable accurate financial statements to be prepared and audited. Companies can store these records electronically, but must be able to produce hard copies within a reasonable timeframe if asked.
Company directors can access financial books and records at all reasonable times. Auditors may need access to company financial records, including when another person holds them. Keep accounting records organised so an auditor can understand the company’s position without relying on scattered emails or informal explanations.
Record-keeping across business structures
When keeping records for different business structures, apply the general tax rules alongside any additional duties for a company or trust. The structure matters: a company’s corporate books are not the same as a sole trader’s records.
Companies are required by ASIC to keep records for 7 years. The Corporations Act 2001 applies to companies registered under that Act, and inadequate financial records can attract ASIC penalties. Sole traders don’t have these company-specific corporate record duties, but still need to retain relevant business tax records.
Keep trust deeds, company constitutions and major legal documents permanently. For a trust, preserve the trust deed alongside records that explain its financial activity. This document provides context for understanding how the trust is structured.
Employee records need their own retention tracking. Employers must keep payroll records for 7 years under Fair Work legislation. Keep records of employee super contributions for 5 years from the contribution date. Super fund choice records must be kept for 5 years from employee engagement, or from when an employee is offered, chooses or changes their fund choice.
Keep business records in English or in a form that can be easily converted to English. The Australian Taxation Office may request records, so retain them in a format that lets you explain transactions and support a tax return. Companies should also back up important documents regularly to preserve access if a main file is damaged or unavailable.
Separate company financial books, payroll records, super records and permanent documents in your filing system. Assign each record type its own retention date instead of applying one disposal date to every file. This helps prevent a routine tax clean-up from removing records that still support company obligations, employee entitlements or an audit.
How long to retain business records
Most Australian business records need to be kept for 5 years, though some circumstances extend that period. According to the Australian Taxation Office, the 5-year period generally starts when a record was prepared or obtained, or when its related transaction or act was completed, whichever is later.
Business record retention period
A retention period is the time you must keep records that support your business tax and super affairs. It matters because the five-year period doesn’t automatically begin on the final day of the financial year.
Income, expense, GST and BAS records generally fall within the 5-year rule. Keep documents that support deductions and explain transactions, including invoices, receipts and accounting entries. Taxation Ruling TR 96/7 discusses general record-keeping principles under section 262A of the Income Tax Assessment Act 1936.
Some records need to stay available longer. If an ATO review or dispute involves a record, keep it until the matter is resolved, even after the usual 5 years. Records supporting a carried-forward loss must be retained until at least the later return’s period of review has ended. Keep loss calculations and supporting evidence together, so the deduction can be traced when used.
Starting the record-keeping period
The start date depends on when the record or related business activity is completed. This matters because the later event sets the beginning of the 5-year retention period.
For example, if an invoice relates to work completed after the invoice was prepared, use the later date to work out the retention period. Record the relevant dates alongside the document. This gives you a clearer basis for deciding when routine records can be removed.
A lodged tax return can also help identify the retention date for supporting evidence. For example, someone lodging a 2025 return on 15 October 2025 should keep its supporting records until at least 15 October 2030. Use the actual lodgement date in your calendar, rather than assuming every business record follows one financial-year disposal date.
Fringe benefits tax records generally need to be retained for 5 years from lodging the FBT return. For the 2023-24 FBT year, records should be kept until at least 21 May 2029 if the return is lodged on time. If an FBT assessment is amended, its review period restarts the day after the amended assessment notice is given.
For borrowing expenses spread over 5 years, retain records long enough to cover the review period for the return containing the final claim. If a file supports several transactions or deductions, use the latest relevant completion date to set its disposal point. That approach helps prevent an early clean-out from removing evidence still needed for an assessment.
Which business records to keep
Keep documents showing business income, expenses and the transactions behind your tax return. A useful record set links each accounting entry to evidence, so you can explain the figures later.
For each reporting period, organise sales invoices, supplier receipts, bank statements and payment processor summaries. These documents help trace money received and paid, including transactions that may not be clear from a single invoice. Keep each supporting record with its accounting entry rather than relying on a vague description such as “supplies” or “sales”.
Other records help explain how amounts were calculated or why a transaction occurred. Keep relevant:
- Contracts and purchase documents that support significant business transactions.
- GST and BAS working papers, plus documents supporting figures reported on each BAS.
- Asset purchase and disposal documents, alongside depreciation calculations and claims.
- Tax-return calculations and schedules supporting deductions or carried-forward losses.
For example, match a supplier invoice with its payment record and accounting entry. This shows what the expense was for, when it occurred and how it was treated in the business accounts. For income, keep invoices or sales records alongside bank deposits or payment summaries. A bank statement may show that money moved, but not the transaction’s business purpose.
A limited receipt exception applies to certain small expenses. An expense of A$10 or less is considered a small expense for this exception. The total claim for small expenses recorded without supplier receipts must be A$200 or less for an income year. Keep any available supporting notes, such as the date, amount and business reason, so the claim can still be explained.
Keep records supporting a carried-forward tax loss until five years after the loss has been fully deducted. Store the loss calculation with the returns showing how it was used. If the loss is applied across later years, this connected file helps explain the original amount and each deduction claimed.
Separate records by type and income year, then label them with the transaction or return they support. For electronic documents, use accounting software or a consistent folder structure to link invoices, receipts and working papers. Keep records in English or a form that can be easily converted to English. This makes documents easier to interpret if the Australian Taxation Office requests them.

Frequently Asked Questions
The short answer: how long should you keep tax records in Australia?
Keep most tax records for at least five years, but the applicable start date depends on the record. Personal tax documents are generally kept for five years from lodging the return; business records can have a different starting point. Before disposing of a file, identify whether it relates to an asset, a carried-forward loss or an unresolved ATO matter.
What happens if you cannot produce tax records?
If you can’t produce records, you may struggle to support income, deductions or transactions included in a return. The Australian Taxation Office can impose an administrative penalty of up to 20 penalty units for failing to keep required records. If records are accidentally lost or destroyed, the ATO may grant relief where you show reasonable precautions and attempts to reconstruct them. Keep copies of reconstructed evidence and explain how you recovered it.
When should you keep records longer than the minimum period?
Keep records longer if they relate to an unresolved ATO review or dispute, a business asset, or a loss used in later returns. For example, an asset file may need to remain available after the asset is sold, while loss evidence stays relevant until the loss is fully deducted and its later review period ends. An amended FBT assessment also affects its review period, which restarts after notice.
How long must Australian businesses keep tax records?
Most Australian businesses must retain tax and super records for five years, though the timing depends on the record and how it’s used. Label each file with the return, transaction or asset it supports. For example, link a sales invoice to the relevant income-year return, while an asset contract should remain with the asset’s records through its later disposal.
What is the ATO record-keeping period for income tax records?
The usual retention period for most business income tax records is five years. Keep evidence explaining income and deductions, such as sales documents, supplier invoices and calculations supporting a tax-return figure. If an income item carries into a later return, keep its supporting workings with the relevant year’s records. This connection helps explain how you calculated a reported amount if the ATO asks.
How long should GST and BAS records be kept in Australia?
Keep GST and BAS records for five years. Retain the documents and workings that explain reported figures, including sales invoices, purchase evidence and records used to reconcile GST amounts. For example, file source documents with the BAS period they support rather than separating all invoices from the calculations. This makes it easier to trace a reported amount to the underlying business transaction.
How long must businesses keep employee and payroll records in Australia?
Employers must keep payroll records for seven years under Fair Work legislation. Records of employee super contributions must be retained for five years from the contribution date. Super fund choice documents have a separate five-year period, measured from employee engagement or the relevant offer, choice or change. Keep these categories distinct: payroll and super contribution records for the same employee can have different disposal dates.
What exceptions require Australian businesses to keep tax records for longer than five years?
Longer retention can apply to capital gains tax assets, depreciating assets, carried-forward losses and records involved in disputes or reviews. Keep CGT asset records while you own the asset and for five years after disposal. The period for depreciating asset records also depends on the last decline-in-value claim. Keep loss records until five years after the loss is fully deducted. For disputes, retain supporting evidence until resolution, even if five years have passed.
