Good business record keeping is about much more than keeping receipts for tax time.
Your records are the evidence behind your BAS, tax returns and financial reports. They show what your business earned, what it spent and how each transaction was treated. Just as importantly, accurate records give you numbers you can actually rely on when running the business.
For Australian businesses, record keeping is also a legal requirement. The ATO requires businesses to keep records of transactions relating to their tax, superannuation and registration affairs.
Most business records need to be kept for five years, although there are circumstances where records must be retained for longer.
For a growing business processing hundreds or thousands of transactions, simply having the records isn’t enough. They also need to be accurate, accessible and connected to the numbers reported in your accounting system.
Quick Summary
- Australian businesses are legally required to keep records relating to their tax, superannuation and registration affairs.
- Most business records must be kept for five years, although some records need to be retained for longer.
- Records can generally be stored electronically, provided they remain accessible and readable.
- Businesses should keep records of income, expenses, assets and other transactions relevant to their tax obligations.
- Where an expense has both business and private use, records should show how the business portion was calculated.
- Accurate records support BAS and tax reporting, but they are also essential for reliable financial reporting.
- Regular bookkeeping and reconciliation can identify missing, duplicated or incorrectly recorded transactions before they become larger problems.
What Records Does an Australian Business Need to Keep?
The records you need depend on what your business does and the taxes and obligations that apply to it.
As a general rule, you need records that explain transactions connected with your business and support the information you report to the ATO.
According to the ATO, businesses need records covering their tax, superannuation and registration affairs as they start, run, change, sell or close the business.
Income and sales records
Keep evidence of the income your business receives. Depending on the business, this may include:
- sales invoices
- tax invoices
- receipts
- cash register records
- records of cash sales
- records of digital sales
- bank records
- payment platform records
For businesses selling across several channels, it’s particularly important that sales recorded by those systems can be reconciled against the accounting records and the amounts landing in the bank.
Expense and purchase records
Businesses should also retain records supporting their expenses and purchases. These can include:
- supplier invoices
- tax invoices
- receipts
- credit card records
- records of cash purchases
- bank statements
- contracts or agreements supporting transactions
A bank transaction on its own doesn’t always show exactly what was purchased or why it was a business expense. Keeping the underlying invoice or receipt makes the record clearer.
Asset records
If your business purchases or disposes of assets, additional records may be required. These can include:
- purchase invoices
- contracts
- settlement documents
- records showing when an asset was acquired
- records showing when it was first used
- records supporting business and private use
- depreciation calculations
- documents relating to the disposal of an asset
Some asset records need to be kept beyond the standard five-year period, because the information can still be relevant years after the original purchase.
GST and BAS records
Businesses registered for GST need records that support the amounts reported on their Business Activity Statements. That may include records supporting:
- GST collected on sales
- GST credits claimed on purchases
- PAYG instalments
- PAYG withholding
- adjustments made in an activity statement
This is one reason regular bookkeeping matters: preparing a BAS shouldn’t mean trying to reconstruct three months of transactions right before the deadline.
When accounts are reconciled regularly, discrepancies can be investigated while the transaction is still relatively recent.
How Long Do Businesses Need to Keep Records in Australia?
For most business records, the answer is five years.
That’s not simply five years from the date printed on every document, though. The ATO states that, generally, the retention period starts from when you prepared or obtained the record, or completed the transaction or act it relates to, whichever is later.
There are also situations where a different starting point applies, or where records need to be kept for longer. Examples can include records connected with:
- depreciating assets
- capital gains tax events
- carried-forward losses
- fringe benefits tax
- employee superannuation
- transactions that remain relevant to a later tax assessment
So it’s worth not automatically deleting every record the moment it turns five years old. If you’re unsure whether a particular document can be destroyed, check its specific record-keeping requirements first.
What Are the ATO’s Five Rules for Business Record Keeping?
1. Keep records relevant to your business
Businesses need to keep records relating to their tax, superannuation and registration affairs. That applies throughout the business lifecycle, from starting the business through to changing, selling or closing it.
2. Protect the information in your records
Records need to be stored in a way that protects them from being damaged or improperly changed. For digital systems, this makes backups, access controls and reliable storage important. Businesses changing accounting platforms or other systems should also consider whether historical information will remain available afterwards.
3. Keep most records for five years
Five years is the general rule, but it isn’t universal. Some records have different retention periods or need to be kept for longer because they continue to support a later transaction, claim or assessment.
4. Be able to produce your records
Keeping a record is only useful if you can retrieve it. If the ATO requests information, your business needs to be able to produce the relevant records. A folder containing thousands of poorly labelled documents may technically contain the information, but a consistent filing and accounting system makes retrieval considerably easier.
5. Keep records in English or able to be converted to English
Business records generally need to be in English or readily convertible into English. That requirement also matters when businesses use overseas suppliers, international platforms or systems that generate documents in another language.
Can Business Records Be Stored Digitally?
Yes. Business records can generally be kept electronically, and digital record keeping can make managing large numbers of invoices, receipts and transactions considerably easier than relying on physical paperwork.
Moving records into the cloud doesn’t remove your record-keeping obligations, though. Electronic records still need to remain:
- secure
- accurate
- accessible
- readable
- protected against unauthorised changes
The ATO also expects businesses to be able to reconstruct original data if a record-keeping system changes over time. That matters when moving between accounting platforms or replacing other financial systems. Historical records shouldn’t disappear just because the software has changed.
Do Businesses Need to Keep Paper Receipts?
Not necessarily. Electronic records can generally satisfy record-keeping requirements, provided they contain the necessary information and remain accessible, so you don’t need filing cabinets full of paper just for the sake of keeping paper.
The more important question is whether the digital record provides sufficient evidence of the transaction. An electronic supplier invoice stored in your accounting or document management system, for example, is usually a much clearer record than a transaction description pulled from a bank feed.
Whichever system you use, it should be consistent enough that documents can still be found several years later.
What If an Expense Is Part Business and Part Private?
Mixed-use expenses require additional care.
If something is used partly for business and partly for private purposes, keep records showing how you calculated the business portion. This can apply to expenses such as vehicles, phones, internet, equipment and other assets used for both business and personal purposes.
The calculation needs to be backed by records you can point to later, not an estimate you can’t explain if asked.
What Happens If Business Records Are Missing?
Missing records can make it harder to substantiate amounts reported in a BAS or tax return. They can also create practical problems long before any ATO review happens.
If supplier invoices go missing, transactions can be coded incorrectly. If sales data doesn’t reconcile with bank deposits, reported revenue becomes unreliable. If transactions are duplicated or left out, management reports can paint a misleading picture of how the business is actually performing.
If records are lost or destroyed, it’s sometimes possible to reconstruct them from other sources: supplier records, bank statements, accounting systems or other platforms, depending on what’s missing. Reconstruction usually takes far longer, though, than maintaining a reliable record-keeping process in the first place.
Why Good Record Keeping Matters Beyond Tax
Tax compliance is only one reason to keep accurate business records. Good records are also the foundation of useful financial reporting.
Your profit and loss statement, balance sheet, cash flow reporting and management dashboards all depend on the transactions underneath them being complete and correctly recorded. No dashboard, however sophisticated, can compensate for unreliable source data.
As we explain in our article on financial data integrity, the reliability of financial reporting comes down to the accuracy, consistency and completeness of the information flowing into the accounting system.
That becomes increasingly important as a business grows. A business with one bank account and a small number of transactions can often spot problems manually. Once there are multiple payment platforms, locations, staff, software integrations and hundreds of monthly transactions, missing or inconsistent records become much harder to catch.
At that point, good record keeping becomes part of the financial infrastructure of the business, rather than just an administrative task.
How Does Bookkeeping Help With Record Keeping?
Record keeping and bookkeeping are closely connected, but they’re not the same thing.
Record keeping is about retaining the evidence behind business transactions. Bookkeeping is about recording, categorising and reconciling those transactions so the accounting records accurately reflect what happened.
For example, keeping a supplier invoice gives you evidence of the purchase. Recording it correctly in the accounting system and reconciling the payment is what makes sure it shows up properly in the financial records.
Regular bookkeeping can help identify:
- missing transactions
- duplicate transactions
- unexplained bank movements
- incorrect transaction coding
- unreconciled accounts
- missing supporting documents
At Cotchy, our bookkeeping and accounting services include regular bookkeeping and reconciliations to help keep business records organised and financial reporting current.
If your bookkeeping has already fallen behind, it’s usually better to deal with the backlog than let missing records and unreconciled transactions keep piling up. Our catch-up bookkeeping service is built to bring overdue financial records back up to date.
What Does Good Business Record Keeping Look Like?
A good record-keeping system doesn’t need to be complicated. It needs to be consistent.
For many businesses, a strong process includes:
- recording transactions regularly
- keeping supporting invoices and receipts
- separating business and private transactions
- reconciling bank and payment accounts
- reviewing outstanding transactions
- keeping digital backups
- limiting unnecessary access to financial records
- retaining historical information when changing systems
- reviewing financial reports regularly
The exact process depends on the size and complexity of the business. The objective stays the same, though: someone should be able to follow a transaction from the original supporting document through to the accounting system and, ultimately, the amount reported in the business’s financial or tax records.
Record Keeping Becomes More Important as Your Business Grows
A record-keeping process that worked when your business was smaller may start to struggle as turnover and transaction volume grow.
More sales usually mean more transactions, and growth tends to bring more staff, bank accounts, credit cards, payment platforms, suppliers and software systems along with it. As that complexity increases, informal processes get harder to control.
This is why growing businesses should review their financial systems before poor processes start affecting reporting. Our guide to scaling financial systems explains how increasing transaction volume and system complexity can expose weaknesses that were manageable when the business was smaller.
Can Poor Records Cause Problems During an ATO Review?
If the ATO asks questions about amounts a business has reported, accurate records make it easier to explain and support those figures.
Poor records don’t automatically mean a business has done something wrong, but incomplete records can make it harder to substantiate transactions or reconstruct what happened.
The ATO uses data from different sources to identify inconsistencies and areas that may require closer review.
Our guide to ATO audit targets for growing businesses covers some of the areas currently getting attention, and why accurate records matter when questions come up.
Records maintained consistently throughout the year put a business in a much better position than trying to fix record keeping after an ATO request lands.
Frequently Asked Questions
How long should a business keep records in Australia?
Most business records need to be kept for five years. However, some records need to be retained for longer, depending on what they relate to and when they remain relevant for tax purposes.
What business records should I keep?
Businesses generally need records supporting income, sales, expenses, purchases, assets, GST, tax, superannuation and other relevant transactions. The records required will depend on the business and its obligations.
Can I keep business records electronically?
Yes. Business records can generally be stored electronically, provided they remain secure, accessible and readable and meet the relevant record-keeping requirements.
Do I need to keep every business receipt?
You need appropriate records to support business transactions and claims. Depending on the transaction, this may include receipts, invoices or other evidence. Do not assume that a bank statement alone will always contain enough information.
Do I need to keep paper copies if I have digital records?
Generally, records can be stored electronically rather than on paper, provided the electronic version satisfies the applicable record-keeping requirements and remains accessible.
What happens if I lose a business receipt or record?
You may be able to reconstruct some missing records using information from suppliers, banks, accounting software or other sources. The appropriate evidence will depend on the transaction and the relevant tax requirement.
Who is responsible for keeping business records?
The business remains responsible for meeting its record-keeping obligations, even where a bookkeeper, accountant or software provider helps maintain the records.
Is bookkeeping the same as record keeping?
No. Record keeping involves retaining evidence of business transactions. Bookkeeping involves recording, categorising and reconciling those transactions to maintain accurate financial accounts. The two work together.
Good Records Make Everything Else Easier
Good business record keeping shouldn’t be something you only think about at tax time.
Accurate, organised records make BAS preparation easier, support your tax reporting and give your accountant or bookkeeper better information to work with. More importantly, they give you financial reports you can actually trust when running the business.
If your accounts are months behind, transactions are sitting unreconciled, or important documents are scattered across emails, folders and different systems, fixing it earlier can save a much bigger clean-up later.
Cotchy provides bookkeeping, accounting, tax and compliance support for Australian businesses, bringing your financial records and reporting together under one team.
If your accounts are behind or your records have become difficult to manage, Cotchy can help bring your bookkeeping up to date and keep your accounts reconciled each month.
