Tax File Number

What Is a Tax File Number?

A Tax File Number (TFN) is a unique, nine-digit personal reference number issued by the Australian Taxation Office (ATO) to every individual, business, or other entity for tax and superannuation purposes. It is a fundamental part of the Australian tax system, acting as a permanent and private identifier that links a person's income, tax payments, and financial records to their identity.

While it is not mandatory to have a TFN, obtaining one is essential for anyone who works or earns income in Australia, as it is required to interact with the tax and superannuation systems effectively.

The Role of a TFN in Employment

For both employers and employees, the TFN is a critical component of the payroll process and tax compliance:

• For Employers: An employee’s TFN is required to correctly calculate and withhold the appropriate amount of Pay As You Go (PAYG) tax from their wages. Employers must also provide the TFN to the ATO when reporting payroll information via Single Touch Payroll (STP), and to the employee’s superannuation fund when making contributions.
• For Employees: Providing a TFN to an employer allows tax to be withheld at the correct rate based on an employee's circumstances (e.g., claiming the tax-free threshold or having a Higher Education Loan Program (HELP) debt). Without a TFN, an employee will be taxed at the highest marginal tax rate, resulting in a significantly lower take-home pay.

Employer Obligations Regarding TFNs

Employers have specific obligations when it comes to managing employee TFNs:

1. Requesting a TFN: You must request a completed Tax File Number Declaration Form from every new employee you hire, within the first 14 days of them starting employment. This form, which can be provided by the ATO, contains the employee’s TFN and other information needed for tax calculations.
2. Processing the Declaration: The information from the TFN Declaration Form must be accurately entered into your payroll system.
3. No TFN Provided: An employee is not legally required to provide a TFN. However, if they do not provide a TFN within 28 days of their start date (or within 28 days of declaring they have applied for a TFN), you must withhold tax from all their payments at the highest marginal tax rate (plus the Medicare Levy). This high rate applies until a valid TFN is provided. Reference: ATO - Tax file number declarations.
4. Data Security: Employers must adhere to the Privacy (Tax File Number) Rule 2015, which mandates strict security measures for the collection, storage, use, and disposal of TFN information. TFNs must be kept secure to prevent identity theft and fraud.

How Microkeeper Manages TFNs

Microkeeper's HR Software and Payroll Software provide tools to streamline the management of TFNs, ensuring compliance with ATO rules:

• Digital Onboarding: New employees can securely provide their TFN and complete the TFN Declaration Form digitally through the Microkeeper employee portal. This process is fully integrated, reducing the risk of errors from manual data entry.
• Secure Storage: All employee information, including TFNs, is stored securely within the Cloud-based Payroll system, protected by advanced security protocols in compliance with data privacy regulations.
• Automated Tax Calculations: Once a TFN and TFN declaration information is in the system, Microkeeper automatically calculates the correct amount of PAYG withholding tax based on ATO tax tables, ensuring accurate and compliant pay runs.
• Non-TFN Management: The system provides clear guidance and functionality for managing employees who have not provided a TFN, automatically applying the highest tax rate after the 28-day grace period.
• Integrated Reporting: TFNs are seamlessly included in all relevant reports to the ATO, including Single Touch Payroll (STP) reporting, meeting employer obligations with each pay run. This is a critical function for businesses in all industries, from Retail to Enterprise.

FAQs About Tax File Numbers

Is it a crime to not have a TFN?‍

No, it is not a crime to not have a TFN. However, if you are a worker or a taxpayer, not having one will result in paying the highest marginal tax rate on your income, and may affect your eligibility for government benefits.

Can I share my TFN with anyone?‍

You should only provide your TFN to authorised individuals or organisations, such as your employer, superannuation fund, financial institution, or the ATO. You should be cautious and never give it to unverified individuals or groups.

What if an employee provides a TFN but doesn't complete the declaration form?‍

If an employee provides a TFN but does not complete a TFN declaration form, the employer is still required to withhold tax at the highest marginal rate. The form provides crucial information for applying correct tax rates and claiming tax offsets.

Can a business use a person’s TFN for identification purposes?‍

No. Under Australian law, a TFN cannot be used as a primary form of identification, such as for renting a property, obtaining a driver's license, or verifying identity for a non-tax-related service.

Best Practices for TFN Management

• Request Immediately: Request the TFN Declaration Form from all new employees on or before their first day.
• Use Secure Systems: Utilise a secure digital platform for TFN collection and storage, avoiding email or insecure channels.
• Automate Calculations: Use payroll software that automatically calculates PAYG withholding based on the TFN and declaration information to ensure accuracy.
• Educate Staff: Inform employees of the benefits of providing their TFN and the consequences of not doing so.

Final Thoughts

The Tax File Number is a cornerstone of Australian tax and superannuation administration. For employers, its correct management is a fundamental aspect of payroll compliance and data security. By implementing secure and automated systems for TFN collection and processing, businesses can ensure accurate tax withholding and maintain their obligations to the ATO and their employees.
