What Is theTax-Free Threshold?
Before diving into what happens if youdont claim the tax-free threshold, lets first understand what it is.
Thetax-free thresholdis the amount of money you can earnwithout paying any income tax. In Australia, this amount is currently$18,200 per financial year. If you earn less than this, you dont pay any tax. Simple, right?
When you start a new job, youll fill out aTax File Number Declaration form, where you can tick a box to claim the tax-free threshold from that employer.
So, What Happens If I Dont Claim It?
Lets cut to the chase.If you dont claim the tax-free threshold, heres what will happen:
1.More Tax Withheld from Your Pay
Your employer will assume youarent claiming any tax-free income, so theyll withholdmore taxfrom each paycheck. Its like giving the ATO an interest-free loan.
Lets say you work part-time and earn $400 a week. If you dont claim the tax-free threshold, more tax is taken out each week even though your total income is below $18,200!
???Real-life example: Emmas First Job
Emma, a university student, landed her first job at a local cafe. She wasnt sure what the tax-free threshold meant, so she left the box unchecked. A few months later, she realised her pay seemed lower than expected. Turns out, she was getting taxed unnecessarily. By not claiming the threshold, Emma was losing around $30 a week thats over$1,500a year!
2.You Might Get a Refund Later (But It Takes Time)
Sure, if you dont claim the tax-free threshold and end up paying too much tax, you may get it back when youlodge your tax return. But why wait months to get money thats already yours?
Thats like buying something for $100 and getting told, Youll get $30 back in July next year. Wouldnt you rather keep that money in your pocket now?
3.Risk of Overpaying or Underpaying
Heres where things get tricky. If you havemore than one job, you can only claim the tax-free threshold fromone employer. If you mistakenly claim it from more than one, you may end upunderpaying taxand owe the ATO at tax time.
