Working Two Jobs Tax Free Threshold Mistake Australia 2026 Guide
Working Two Jobs Tax Free Threshold Mistake (Australia 2026 Guide)
Why You May Owe Tax & How to Fix It Before EOFY
๐จ Working Two Jobs? You Could Be Overpaying Tax Later
If youโre working two jobs in Australia and end up owing money at tax time, the issue is usually not your income โ itโs how your tax is set up.
One of the most common mistakes is claiming the tax-free threshold from more than one employer.
๐ While this increases your take-home pay during the year, it often leads to a surprise tax bill when you lodge your return.
๐ What Is the Tax-Free Threshold in Australia?
The tax-free threshold is the amount you can earn before paying income tax.
๐ For the 2026 financial year, the threshold is $18,200.
Important:
This applies to your total income, not each job separately.
โ What Is the Working Two Jobs Tax Free Threshold Mistake?
When you start a job, you complete a Tax File Number (TFN) declaration.
You are asked:
๐ โDo you want to claim the tax-free threshold from this payer?โ
- โ๏ธ Yes โ No tax on first $18,200
- โ No โ Tax from first dollar
๐ซ The Mistake:
If you select โYesโ for multiple jobs:
- Both employers reduce your tax withholding
- Less tax is deducted overall
- You unknowingly underpay tax throughout the year
๐ Result: You owe money to the ATO at tax time
๐ Why This Mistake Leads to a Tax Bill
Australia uses a progressive tax system, meaning your total income determines your tax rate.
Example:
- Job 1 income: $45,000
- Job 2 income: $30,000
- Total income: $75,000
Each employer calculates tax separately, but the ATO calculates tax on the full $75,000.
๐ Because insufficient tax was withheld during the year, you must pay the difference.
โ ๏ธ Additional Factors That Increase Your Tax Bill
๐ HELP / HECS Debt
If you have a study loan:
- Repayments are based on combined income
- If not declared to all employers โ no withholding occurs
- ATO adds repayment at tax time โ larger tax bill
๐ฅ Medicare Levy
- Typically 2% of taxable income
- Calculated on total income
- Can increase your final tax payable
