Getting Your Tax File Number (TFN) | AC878 Guides

Why You Need a TFN Immediately

A Tax File Number is your unique identifier for tax and superannuation purposes in Australia. Without one, you'll face severe financial penalties:

• Employment: Employers withhold tax at 47% (highest marginal rate) instead of your actual rate (potentially 0-45%)
• Banking: Banks withhold tax at 47% on all interest earned
• Superannuation: Super funds charge 47% tax instead of 15%
• Government payments: Unable to claim tax offsets or rebates

Cost Example: On a $60,000 salary without TFN, you'd pay $28,200 tax instead of $11,067 — that's $17,133 extra! While refundable, it ties up your money for months.

Starting Work Before TFN Arrives

You can start working immediately without waiting for your TFN to arrive:

1. Complete TFN Declaration: Form provided by employer
2. Tick 'Applied for TFN': Shows application in progress
3. Sign statutory declaration: Confirms application details
4. Provide TFN later: Maximum 28 days from start date

Pro Tip: Save your ATO online application confirmation — this proves to employers that you've applied and qualifies you for normal tax rates while waiting.
