A Tax File Number (TFN) is a unique identifier issued by the Australian Government and managed by the Australian Taxation Office (ATO). It stays with an individual for life and is essential for managing tax and superannuation obligations.
In payroll, the TFN plays a critical role in ensuring accurate PAYG withholding, correct employee taxation, and full compliance with Australian tax laws.

Employers must withhold tax from employee wages under the PAYG system.
The TFN declaration ensures the correct tax rates are applied based on the employeeโs circumstances.

If an employee does not provide a TFN, employers are required to withhold tax at the highest marginal rate (currently up to 47%, including Medicare levy).
๐ While providing a TFN is optional, not providing one results in significantly higher tax deductions.

New employees should complete a TFN Declaration form at the start of employment.
This form helps determine:
- Tax-free threshold eligibility
- Residency status
- Applicable PAYG withholding rates
