👋 Welcome to Clear Tax Accountants!

Let’s get straight to it: Your tax file number (TFN) is one of the most important numbers you’ll ever have in Australia. It’s your personal key to managing tax and superannuation, and without it, you’re going to be paying more tax than you need to. Who wants that?

So, if you’ve just started a new job or are planning on doing so soon, do you have your TFN sorted? Because the consequences of not having one go far beyond just a bit of extra tax. Let’s break it down.

What Exactly is a Tax File Number (TFN)?

Alright, let’s start with the basics. A tax file number (TFN) is a unique number issued by the Australian Taxation Office (ATO) to identify you in the tax system. Think of it like your personal ID for anything tax-related.

Why? Because without a TFN, your employer is required to withhold tax at the highest rate. That’s 47% of your earnings—almost half of your pay gone. And that’s just one of the headaches. Without a TFN, you also:

Paying More Tax – The Unnecessary Penalty

Now, let’s really talk about the elephant in the room – paying more tax. Imagine earning $1,000 in a week but watching almost $500 of that disappear in tax.

That’s what happens when you don’t have a TFN.

When your employer doesn’t have your TFN, they don’t have a choice. They legally must withhold tax at the highest rate.

And no, it’s not something you can just ‘fix later’.
