Starting a new job? You’re probably looking at that Tax File Number (TFN) declaration form and wondering whether to tick ‘Yes’ to claim the tax-free threshold. It’s a small box, but it has a big impact on your take-home pay.

Understanding the tax-free threshold is key to managing your finances effectively. It helps reduce how much tax is withheld from your pay throughout the year, but you need to know exactly when and how to claim it. This guide will walk you through everything you need to know about how to claim tax-free threshold Australia 2025, ensuring you stay compliant with the ATO and keep more of your hard-earned money in your pocket.

What Is the Tax-Free Threshold?

In simple terms, the tax-free threshold is the amount of income you can earn each year before you have to start paying tax. For Australian residents, this amount is currently $18,200. This is a core feature of Australia’s Pay As You Go (PAYG) tax system, designed to give workers a tax-free buffer on their initial earnings.

When you start a new job and correctly claim the threshold, your employer won’t deduct any tax from the first $18,200 you earn. This means your regular take-home pay is higher.

If you don’t claim it, your employer withholds more tax from every dollar you earn. While this often results in a larger tax refund at the end of the financial year, it means your take-home pay is lower throughout the year. Essentially, you’re giving the ATO an interest-free loan. Knowing how to claim tax-free threshold Australia 2025 correctly puts you in control.

How to Claim the Tax-Free Threshold in 2025

The process of claiming tax-free threshold is straightforward and is usually handled when you first start a new job. Here’s a simple step-by-step guide:

1. Receive the TFN Declaration Form: Your new employer will provide you with a Tax File Number (TFN) declaration form. This can be a paper copy or a digital version through their payroll system.
2. Fill in Your Details: Complete your personal details, including your Tax File Number (TFN).
3. Answer Question 8: This is the crucial step. The form will ask: “Do you want to claim the tax-free threshold from this payer?” You need to tick “Yes”.
4. Claim from Your Main Employer Only: This is the golden rule. You should only ever claim the threshold from your primary income source the job that pays you the most. If you have a second job, you must tick “No” on the form for that employer.
5. Submit the Form: Once completed and signed, return the form to your employer. They are responsible for reporting this information to the Australian Taxation Office (ATO).

You do not need to resubmit this form every year. It remains active with that employer unless you change jobs or your tax situation changes (e.g., you start a second job).

Common Scenarios

Let’s look at how claiming tax-free threshold works in a few real-life examples.

Example 1: Chloe works one full-time job Chloe has just started her first full-time role. Since this is her only job, she should tick “Yes” to claim the tax-free threshold from this employer. This ensures her take-home pay is maximised throughout the year.

Example 2: Jake has 2 jobs Jake works two part-time jobs. His first job pays $40,000 per year, and his second pays $20,000. To comply with second job tax rules, Jake must:

• Claim the tax-free threshold from his higher-paying job ($40,000).
• Do NOT claim the threshold from his second, lower-paying job. He must tick “No” on the TFN Declaration form for this job.

Example 3: Lisa is a student starting her first job Lisa is a university student who has just started a part-time job. As this is her only source of income, she should claim the tax-free threshold to ensure less tax is withheld from her pay.

What if I accidentally claim it from both jobs? This is a common mistake. If you realise you’ve claimed the threshold from two (or more) jobs, you need to fix it immediately. Contact your second, lower-paying employer and ask for a new TFN declaration form. Fill it out and tick “No” to stop claiming the threshold. This will prevent a large tax bill at the end of the year.

What if I forget to claim it? Forgetting to claim the threshold means more tax withheld from your pay than necessary. While your take-home pay will be lower, you haven’t lost the money. You will receive it back as a larger refund when you lodge your tax return. You can submit a new TFN declaration to your employer at any time to start claiming it.

Benefits, Mistakes to Avoid, and Pro Advice

Understanding how to claim tax-free threshold Australia 2025 comes with clear benefits, but there are also common pitfalls to avoid.

Benefits:

• More take-home pay throughout the year: This is the biggest advantage, improving your weekly or fortnightly cash flow.
• Reduces the chance of over-taxation: Claiming correctly ensures you pay the right amount of tax during the year, avoiding giving the Australian Taxation Office (ATO) an interest-free loan.

Mistakes to Avoid:

• Claiming from multiple employers at once: This is the most critical mistake. It will almost certainly result in a tax debt at the end of the financial year.
• Not updating your TFN declaration when your job changes: If you switch to a new, higher-paying primary job, you must update your declaration for both the new and old employers.
• Assuming the threshold applies automatically: It doesn’t. You must actively opt-in by ticking “Yes” on your declaration form.

Pro Tip: If you’ve made a mistake in the past, like claiming the threshold from multiple jobs, or if your income situation is complex, a registered tax agent can help. They can assist you in lodging an updated TFN declaration with the ATO to correct errors and ensure you’re on the right track. This is especially useful when figuring out how to claim tax-free threshold Australia 2025 with multiple income streams.

FAQs

Here are answers to some of the most frequently asked questions about claiming tax-free threshold.

1. How do I claim the tax-free threshold in Australia 2025?

You claim it by ticking “Yes” to question 8 on the Tax File Number (TFN) Declaration form provided by your employer when you start a new job. This tells your employer not to withhold tax on the first $18,200 of your annual income.

2. Can I claim the threshold from more than one job?

No. You can only claim the tax-free threshold from one employer at a time. It should be claimed from your main, highest-paying job to avoid an end-of-year tax bill. This is a key part of the second job tax rules.

3. What happens if I don’t claim the tax-free threshold?

If you don’t claim it, your employer will withhold tax from the first dollar you earn. This reduces your regular take-home pay, but you will likely receive a larger tax refund after you lodge your annual tax return.

4. Is the tax-free threshold applied automatically?

No, it is not. You must make an active choice by completing the TFN Declaration form. If you fail to do so, your employer is required to withhold tax withheld at the higher, “no tax-free threshold” rate.

5. Do I need to claim it every year?

No. You only need to complete a TFN Declaration once for each employer. The instruction remains in place for the duration of your employment with them unless your circumstances change.

Conclusion

Claiming the tax-free threshold is a simple but powerful way to manage your income and ensure you have more cash on hand throughout the year. By understanding the rules, especially the one-employer rule, you can avoid common pitfalls and stay on the right side of the ATO. Knowing how to claim tax-free threshold Australia 2025 correctly puts you in a better financial position.

Remember, the key is to claim it from your main source of income and update your declarations if your work situation changes. It’s all about making sure you are taxed correctly from the start.
