Why might an employer request your TFN?

An employer requests your Tax File Number (TFN) primarily to ensure accurate tax withholding from your salary. The TFN serves as a unique identifier for individuals within the tax system, allowing employers to deduct the correct amount of tax from your earnings. This is crucial for compliance with tax laws and regulations, ensuring that you pay the appropriate amount of income tax based on your earnings. Through the use of your TFN, your employer can also report your income and tax information to the Australian Taxation Office (ATO) accurately, which is essential for both you as an employee and for the employer to fulfill their legal obligations regarding taxation.

While options related to tracking employment history, opening bank accounts, or processing superannuation contributions are relevant in different contexts, the primary reason for providing a TFN focuses directly on taxation and payroll processes.
