Common questions
How much tax will I pay on my side hustle income?▼
Your side hustle profit is added on top of your salary and taxed at your marginal rate — the rate that applies to your highest slice of income. If your combined income is between $45,001 and $135,000, that rate is 30%. Between $135,001 and $190,000 it's 37%. Above $190,000 it's 45%. Plus the 2% Medicare levy. Use the calculator above to get an exact figure based on your actual numbers.
Do I need to register for GST for my side hustle?▼
Only if your side hustle revenue reaches $75,000 in any 12-month rolling period. Once you cross that threshold you must register within 21 days — penalties apply for late registration. Below the threshold, GST registration is optional. Note: rideshare drivers (Uber, Ola, DiDi) must register from their very first trip regardless of earnings.
Why is the tax rate on my side hustle higher than on my salary?▼
Your employer withholds PAYG tax from your salary assuming it's your only income — so the tax-free threshold and lower brackets are already used up. Side hustle income gets stacked on top and taxed at your highest marginal rate from the first dollar. This is why someone on an $80,000 salary pays 30% on every dollar of side hustle income, even if the side hustle only earns $5,000.
What does the "second job / no tax-free threshold" toggle do?▼
If you have a second job, or your side hustle is your main income source and you haven't claimed the tax-free threshold on your tax declaration form, your income is taxed from the first dollar at 16% rather than being tax-free up to $18,200. Tick this box if your employer withholds tax at the "no TFT" rate, or if this is a genuine second income on top of your main job.
Will the ATO know about my side hustle income?▼
Very likely yes. Since 2024, the ATO's Sharing Economy Reporting Regime requires platforms like Uber, Airbnb, Etsy, and Airtasker to report earnings directly to the ATO. The ATO also receives data from banks, PayPal, Stripe, and other payment processors. Undeclared income is a high-priority audit area in 2026.
How do I pay the tax I owe on my side hustle?▼
For most side hustlers, you declare the income in your annual tax return and pay any balance owing at that point. If your tax liability exceeds $1,000 and not enough is withheld through employment, the ATO may ask you to pay quarterly PAYG instalments the following year. The calculator estimates what those quarterly amounts would be — use the quarterly row in your results.
