16. Frequently Asked Questions
Q: Do I need to lodge a tax return if I earn under $18,200?
A: If you earned less than $18,200 and had no tax withheld, you generally don’t need to lodge a return. However, if you had tax withheld or are eligible for offsets, you should lodge to get a refund.
Q: What’s the difference between taxable income and gross income?
A: Gross income is your total income before any deductions. Taxable income is what remains after you subtract allowable deductions from your gross income.
Q: How does the ATO know if I don’t declare all my income?
A: The ATO receives data from banks, employers, share registries, and other sources. Their sophisticated data-matching systems can identify discrepancies in reported income.
Q: Can I claim home office expenses?
A: Yes, if you work from home, you can claim either:
- A fixed rate of 67 cents per hour (2022-2023)
- Actual expenses (with detailed records)
Q: What happens if I lodge my tax return late?
A: You may incur a failure-to-lodge (FTL) penalty, which is calculated at the rate of one penalty unit for each period of 28 days that the document is overdue, up to a maximum of five penalty units.
Q: How long should I keep my tax records?
A: Generally, you must keep records for 5 years from the date you lodge your tax return, or 5 years from the date the record was created (whichever is later).
