What Tax Return Means
A tax return is a procedure to report income and calculate income tax. Not everyone needs the same procedure, but some situations need confirmation.
Common Situations to Check
You should check if you had side income, changed jobs, quit work, worked at more than one place, had medical expenses, or support family overseas.
Documents to Keep
Keep withholding tax slips, payslips, insurance documents, medical receipts, remittance documents, and My Number information if required.
Where to Ask
Tax offices, the National Tax Agency website, city offices, and consultation events may help. Some areas provide foreign language information.
Do It Before the Deadline
Tax procedures have deadlines. If you are not sure, check early instead of waiting until the last week.
