Australia’s taxation system is largely based on the principle of self assessment. Preparation and lodgement of an income tax return are key parts of the self assessment system.

Tax return preparation requires taxpayers to provide information about their income, deductions and any tax offsets to which they may be entitled, so that the tax laws are properly applied to their affairs.

Responsibility for the accuracy and completeness of information, required to comply with taxation laws, rests with the taxpayer.

Taxpayers are obliged to keep records, generally for five years from the date of the transaction, and to provide information to the ATO when requested. Failure to keep certain records can lead to adverse outcomes, such as denial of deductions for expenses or loss of entitlement to other relief.

While the ATO generally accepts tax returns at face value, under the self assessment system returns are subject to review, including audit and verification checks.

The ATO can amend assessments to correct calculation errors, mistakes of fact or law, within two years or four years following assessment, depending on the complexity of your affairs. In some circumstances the period can be longer. Taxpayers dissatisfied with amended assessments of tax and penalties have the right to object and if dissatisfied with the ATO’s review, to appeal.

To limit the risk and uncertainty associated with self assessment, taxpayers can request a private ruling to obtain formal advice from the ATO about how the taxation law applies to a transaction.

There are statutory safe harbours that may protect taxpayers from administrative penalties for false or misleading tax returns and statements given to the ATO, as well as late lodged tax returns and statements, where the taxpayer has given their tax agent all relevant information but the agent has not exercised reasonable care.
