  • Fact 21

    As overseas travel became more common in the 1960s, the ATO stopped issuing tax clearance certificates (which had previously reminded Australians planning on travel that they must ensure they had paid all tax owed prior to leaving the country).

Self-assessment

Australia's tax system works on self-assessment. When a taxpayer completes their income tax return, they must show all of their income and only claim allowable deductions and tax offsets to which they are entitled. The ATO issues a notice of assessment based on the information provided in the tax return.
