What Is ATO Data Matching?
ATO data matching generally refers to the process of comparing information available to the Australian Taxation Office with information reported by taxpayers.
The ATO receives information from a variety of organisations and third parties. This information can help with pre-filling tax returns, checking reported income and identifying situations that may require further review.
For taxpayers, the key message is simple: information should be reported accurately and supported by appropriate records.
Data matching is a normal part of Australia's tax administration system. A match or discrepancy does not automatically mean a taxpayer has deliberately provided incorrect information. Sometimes differences can arise because information is incomplete, delayed or needs clarification.
Where Can the ATO Receive Information From?
Depending on the type of income or transaction, information may be reported to the ATO by various third parties.
Employers
Salary, wages and PAYG withholding information may be reported through Australian payroll and reporting systems.
Banks & Financial Institutions
Information such as bank interest and certain investment-related amounts may be available to the ATO.
Government Bodies
Information held by Australian government agencies may be relevant to tax administration in appropriate circumstances.
Other Reporting Organisations
Depending on the activity, the ATO may receive information connected with investments, property, business or platform-based income.
What Is Pre-Filled Tax Information?
When you prepare an Australian tax return, some information may already appear in the return.
This is commonly referred to as pre-filled information.
Pre-fill can make tax preparation easier because some information reported by third parties may already be available.
However, pre-filled information should not be treated as a replacement for checking your own records.
Check pre-filled amounts against income statements, bank records, investment documents and other relevant records. Information can sometimes arrive at different times, so review your return carefully before lodging.
Employment Income and Data Matching
Employment income is one of the most common types of information taxpayers see in their return.
Employers generally report payroll information, including salary and wages and tax withheld, through Australian reporting systems.
At tax time, income statement information may appear in myGov or in information available to a registered tax agent.
If you worked for more than one employer during the year, check that all relevant employment income is included.
A worker had three employers during the year
Imagine a Nepali worker starts the year working in hospitality, later moves to a warehouse job and then begins working in aged care.
Even though the worker only has one job at the end of the year, income from all relevant employers during the financial year may still need to be included in the tax return.
Checking each income statement before lodging can help identify whether anything appears to be missing or incorrect.
Bank Interest Can Also Matter
Bank interest is another common area taxpayers can overlook.
Even if the amount seems small, assessable interest may still need to be included in the tax return.
Information reported by financial institutions may appear as pre-filled information.
Taxpayers with multiple bank accounts should check that relevant interest information is correctly reported.
What About Joint Bank Accounts?
Joint accounts can require additional attention.
How interest should be reported can depend on ownership and the circumstances of the account.
Do not automatically assume that all interest should be reported by only one account holder simply because one person manages the household finances.
Shares and Investment Income
Investors may have income or transactions involving shares, managed investments or other financial assets.
Relevant information may come from investment providers or other reporting entities.
Taxpayers should still keep their own investment statements, transaction records and supporting documents.
Pre-filled information may not contain everything required to determine the final tax treatment of an investment.
Cryptocurrency and Digital Assets
Cryptocurrency transactions can also create Australian tax obligations depending on how the digital assets are acquired, held, transferred or disposed of.
The fact that an activity occurs through an online platform does not automatically place it outside Australia's tax system.
People who buy, sell, swap or otherwise deal with crypto assets should maintain suitable transaction records and determine the applicable tax treatment.
Uber, DoorDash and Other Platform Income
Many Nepali workers in Australia earn additional income through rideshare, food delivery or other digital platforms.
Income earned through these activities should not simply be ignored because it is separate from a person's normal salary.
Depending on the activity and circumstances, platform earnings may need to be included as business or other assessable income.
ABN, GST, business expenses and record-keeping requirements may also need to be considered.
Cash Income Is Still Income
Receiving payment in cash does not automatically make that income tax-free.
If income is assessable under Australian tax rules, the method of payment does not by itself remove the requirement to report it.
This can apply whether payment is received through cash, bank transfer or another payment method.
Rental Property Information
Property owners should ensure that relevant rental income and eligible property expenses are properly recorded.
Property transactions and ownership information may also be available through Australian reporting and government systems.
Keep records such as rental statements, interest details, agent fees, repairs, insurance and other relevant property documents.
What Information Should You Check Before Lodging?
| Information | What to Check |
|---|---|
| Employment income | Check each employer, gross income, PAYG withholding and income statement status. |
| Bank interest | Review relevant bank accounts and compare amounts with your records. |
| Investment income | Check dividends, distributions and other relevant investment records. |
| ABN income | Review invoices, platform statements, bank deposits and business records. |
| Rental income | Check rental statements and relevant property records. |
| Other income | Consider other income sources that may need to be declared. |
What If Pre-Filled Information Is Missing?
Information may not necessarily appear immediately.
Different organisations can finalise and report information at different times.
This is one reason taxpayers should avoid assuming that an empty pre-fill field automatically means there is nothing to report.
Use your own records to determine whether relevant income or other information needs to be included.
What If the Pre-Filled Amount Looks Wrong?
Do not automatically change information without first checking the underlying records.
Compare the amount with your income statement, bank statement, investment statement or other supporting document.
If information appears incorrect, you may need to contact the organisation that reported it or seek professional assistance before lodging.
What Happens If Your Tax Return Does Not Match?
If information reported in a tax return differs from information available to the ATO, the difference may potentially be reviewed.
A difference does not always mean something is wrong. There may be a legitimate explanation.
However, taxpayers should be able to explain their tax return position and maintain appropriate records supporting income and deductions.
What If You Forgot to Declare Income?
Mistakes can happen.
If you discover after lodging that relevant income or another item was omitted or incorrectly reported, the return may need to be corrected through the appropriate amendment process.
The correct approach depends on the nature of the error and your circumstances.
If you are unsure, consider speaking with a registered tax professional rather than ignoring the issue.
Data Matching and Tax Deductions
Data matching is not only about income.
The ATO may also review deductions and other amounts reported in returns using available information, patterns and compliance processes.
A deduction should not be claimed simply because software allows you to enter an amount.
You generally need to satisfy the relevant deduction rules and keep appropriate evidence where required.
A taxpayer may legitimately have significant work or business expenses. The important point is whether the expenses are actually deductible under the relevant rules and whether suitable records support the claim.
Common Mistakes to Avoid
Previous employers can still be relevant even if you no longer work for them.
Compare available information with your own records before lodging.
Small income amounts may still be relevant to your tax return.
Rideshare, delivery, freelancing and other income may still need to be reported.
Keep appropriate records and make sure expenses satisfy the applicable deduction rules.
Data Matching for Nepali Students in Australia
Nepali students may work for several employers during a financial year.
Hospitality, cleaning, retail, warehousing, aged care and delivery work are common examples.
Students should check all relevant income statements, bank interest and any ABN or platform income before lodging.
Changing jobs during the year does not mean income from the previous employer disappears from the tax return.
Data Matching for ABN Workers and Sole Traders
Sole traders need to take additional care because their income may not look exactly like a normal employee income statement.
Business owners should maintain their own records showing:
- business income
- invoices
- bank deposits
- platform statements
- eligible expenses
- GST records where applicable
- BAS records where applicable
- other relevant business documents
Should You Wait for Information to Be Finalised?
Where information is still being finalised, lodging too quickly can increase the risk of using incomplete figures.
For employment income, check whether relevant income statements are ready and compare them with your records.
Waiting until important information is available can make it easier to prepare a more accurate return.
Keep Your Own Tax Records
One of the biggest lessons from data matching is that taxpayers should not depend entirely on information stored elsewhere.
Maintain your own records throughout the year.
- income statements
- payslips
- bank statements
- receipts
- invoices
- vehicle or travel records where relevant
- investment documents
- rental property records
- business records
