Every year thousands of Australians pay too much or too little tax because they misunderstand one simple concept: the tax-free threshold. This guide explains the rules in plain English so you can avoid surprises at tax time.
Key Takeaways
- What it is: The tax-free threshold is the amount of income you can earn before paying tax in Australia, currently set at $18,200 for eligible residents.
- How it works: Claiming it with an employer reduces the Pay As You Go (PAYG) tax withheld from your wages, increasing your take-home pay.
- The Golden Rule: Eligible residents should only claim it at one job at a time, usually the one that pays the most.
- Multiple Jobs: Claiming the threshold at multiple jobs at once is a common mistake that can lead to a tax debt at the end of the financial year.
- Special Cases: Non-residents and working holiday makers have different tax rules and may not be eligible for the standard threshold.
- Stay Updated: Always check current ATO guidance, as tax rules and thresholds can change.
What is the tax-free threshold in Australia?
So, what is the tax-free threshold in Australia, exactly? It’s a set amount of income you can earn each financial year before you have to pay a cent of income tax.
For Australian residents for tax purposes, this amount is currently $18,200. It’s a core part of our progressive tax system, where your tax rate increases as your income moves through different Australian tax brackets. The threshold simply ensures that the first chunk of your earnings is yours to keep, completely tax-free.
When you start a new job, your employer will give you a Tax File Number (TFN) Declaration form. This is where you tell them whether to “claim” the tax-free threshold for that role.
- Claiming the threshold instructs your employer to apply this $18,200 buffer when they calculate your pay. They’ll withhold less tax each pay cycle, meaning more cash in your pocket.
- Not claiming the threshold tells them to tax you from the very first dollar you earn. Your take-home pay will be smaller, but you’ll likely get a bigger tax refund when you lodge your return.
This single decision has a direct impact on your cash flow throughout the year. The Australian Taxation Office (ATO) is clear: you should only claim it from one employer at a time to ensure you’re paying the right amount of tax. Always check the latest ATO guidance as rules and rates can change.
How the tax-free threshold affects PAYG withholding
That little box you tick on your TFN Declaration form has a real, immediate impact on your bank account each payday.
Deciding to claim the tax-free threshold directly tells your employer’s payroll system how much tax to hold back from your earnings. This is known as PAYG (Pay As You Go) withholding, and your choice sets the rules for the whole year.
When you claim the threshold, you’re telling your employer to apply the $18,200 tax-free buffer. The result? Less tax is withheld from each pay cheque, which means more money lands in your account. If you don’t claim it, they have to tax you from the very first dollar you earn, leading to higher withholding and less take-home pay.
Withholding outcomes with vs without the threshold
Let’s see how this plays out. Imagine two colleagues earning the exact same weekly wage. The only difference is how they filled out their TFN Declaration. This table shows the instant impact.
To illustrate, let’s look at two employees who both earn $900 per week before tax.
Weekly Pay With and Without Claiming the Tax-Free Threshold This table shows the real-world difference in tax withheld and take-home pay on a $900 weekly wage, based on your tax-free threshold claim.
| Scenario | Threshold Claimed? | Weekly Tax Withheld (Approx.) | Weekly Take-Home Pay (Approx.) |
|---|---|---|---|
| Employee A | Yes | $129 | $771 |
| Employee B | No | $219 | $681 |
As you can see, Employee A takes home an extra $90 every single week just by ticking the right box.
While Employee B will likely get that extra tax back as a refund, they’re essentially giving the ATO an interest-free loan with their own money. This highlights the cash flow benefit of correctly claiming the threshold at your main job.
Should you claim the tax-free threshold?
This is the big decision every employee has to make. The golden rule is to claim the threshold at your primary, highest-paying job and never at a second one. Getting this right is your best defence against a surprise tax bill.
The ATO looks at your total taxable income from all sources when you lodge your return. But you only get one tax-free threshold of $18,200. If you claim it at two jobs, neither employer will withhold enough tax to cover your combined income, leaving you with a shortfall you’ll have to pay back.
Checklist: Before you decide to claim
- You should claim the threshold if:
- You have only one job.
- This is your main job (the one that pays you the most).
- You are an Australian resident for tax purposes.
- You should NOT claim the threshold if:
- This is a second or third job.
- You are already claiming the threshold with another employer.
- You receive a taxable government payment or pension and you’re also working.
- You are a foreign resident for tax purposes.
By not claiming it at a second job, your employer will withhold tax from the first dollar you earn. While your take-home pay from that job will be lower, this higher withholding rate is what prevents a tax debt when all your income is added together. It’s always a good idea to double-check the latest ATO guidance to confirm where you stand.
Claiming with multiple jobs – risks and rules
Juggling more than one job is common, but it can easily lead to a tax headache. The rule is simple but firm: claim the tax-free threshold from one job only.
Typically, you’ll want to claim it from your highest-paying job. For your second job, you must tick the box on your TFN Declaration form that says you do not want to claim it. This tells your second employer to withhold tax from the very first dollar, which is crucial for covering your total tax liability. Failing to do this is a common mistake that often results in a tax bill. For a deeper look, check out our guide on how a second job is taxed in Australia.
Worked Example: Claiming the threshold at one job vs two jobs
Let’s look at Alex, who works two part-time jobs.
- Job A (Main Job): Earns $30,000 per year.
- Job B (Second Job): Earns $20,000 per year.
- Total Income: $50,000 per year.
Scenario 1 (Correct): Alex claims the threshold only at Job A.
- Job A: Withholds tax on income above $18,200.
- Job B: Withholds tax on the full $20,000.
- Result: Enough tax is withheld throughout the year to cover the liability on the total $50,000 income. Alex likely has no tax bill or a small refund.
Scenario 2 (Incorrect): Alex claims the threshold at both jobs.
- Job A: Withholds tax on income above $18,200.
- Job B: Also withholds tax on income above $18,200 (treating it as the main job).
- Result: Neither employer withholds enough tax. The ATO sees a total income of $50,000 but only one $18,200 threshold applies, leading to a significant tax bill for Alex.
Resident, non-resident and working holiday maker differences
Your residency status for tax purposes determines your eligibility for the threshold. Not everyone gets the same treatment.
- Non-Residents: If you’re a foreign resident for tax purposes, you generally are not entitled to the tax-free threshold. Tax is typically withheld from the first dollar of income you earn in Australia.
- Working Holiday Makers: People on 417 or 462 visas play by different rules. They pay a specific, flat tax rate on their income up to a certain limit and don’t get access to the standard resident threshold. For the latest rates, it’s best to refer to the ATO’s guidance for working holiday makers.
How to claim or update the threshold
Putting your decision into action is simple. It all comes down to the ATO’s Tax File Number (TFN) Declaration form.
This form officially tells your employer how to handle your PAYG withholding. Your boss will usually give you a copy when you start. If your circumstances change, you just need to fill out a new one.
A Step-by-Step Guide to Your TFN Declaration
- Get the Form: Your employer’s HR or payroll team will provide this. Many businesses now use digital platforms like Xero or MYOB, so you might get an email link.
- Fill in Your Details: Ensure your name, address, and Tax File Number are correct.
- Answer the Key Question: Find the question that asks: “Do you want to claim the tax-free threshold from this payer?”
- Tick ‘Yes’ if this is your only job or your highest-paying one.
- Tick ‘No’ if this is a second job and you’re already claiming the threshold elsewhere.
- Sign and Submit: Sign the form and return it to your employer. They’ll adjust your PAYG withholding accordingly.

Common mistakes and quick fixes
It’s easy to create a tax headache with a few simple errors. Here are the most common slip-ups and how to fix them.
Claiming at More Than One Job
This is the number one mistake. Both employers withhold less tax, assuming they’re your only income source. This almost always leads to a tax bill.
- Quick Fix: Immediately get a new TFN Declaration form. Give it to your second-highest paying employer and tick ‘No’ for claiming the threshold. This corrects your PAYG withholding going forward.
Forgetting to Update Your Declaration
Life changes. If your main job ends and a part-time gig becomes your primary income, you need to update your declaration. If you don’t, that employer will continue withholding tax at the higher rate as if it’s still your second job.
- Quick Fix: Give your current primary employer a new TFN Declaration, but this time, tick ‘Yes’ to claim the threshold. Your take-home pay will increase in the next pay cycle.
Not Claiming the Threshold at All
Some people play it extra safe and don’t claim the threshold, even with just one job. While it guarantees you won’t get a tax bill, you’re giving the ATO an interest-free loan all year, which reduces your cash flow.
- Quick Fix: If you only have one employer, lodge a new TFN Declaration claiming the threshold. You’ll immediately see a difference in your weekly take-home pay.
FAQs
What is the tax-free threshold in 2025 for Australian residents?
For the 2024-2025 financial year, the tax-free threshold for Australian residents for tax purposes is $18,200. This means you can earn up to this amount without paying any income tax. Always check the official ATO website for the most current figures.
What happens if I claim the tax-free threshold at two jobs?
If you claim the threshold at two jobs, neither employer will withhold enough tax. When you lodge your tax return, the ATO will assess your combined income but only apply the single $18,200 threshold. This typically results in a tax debt that you will need to pay back.
Can I change my tax-free threshold claim partway through the year?
Yes, absolutely. You can change which job you claim the threshold from at any time. Simply complete a new Tax File Number Declaration form and give it to your employer(s) to update your PAYG withholding arrangements.
Do non-residents get the same tax-free threshold?
Generally, no. If you are a foreign resident for tax purposes, you usually cannot claim the tax-free threshold. This means you will be taxed from the very first dollar you earn in Australia. Different rules and tax rates apply, so check the ATO website for details specific to your situation.
Do I still get the full threshold if I only work for part of the year?
If you are an Australian resident for the full tax year, you are entitled to the full $18,200 threshold. The ATO applies it to your total annual taxable income when you lodge your return, regardless of whether you earned that income over two months or twelve.
