What happens if a person does not have a TFN but is required to file taxes?

If a person does not have a Tax File Number (TFN) but is required to file taxes, they may face fines. The TFN is crucial for identifying individuals within the tax system, and without it, the Australian Taxation Office (ATO) cannot properly process tax returns or ensure compliance with tax obligations. Failing to provide a TFN can lead to penalties because the ATO has specific regulations that demand accurate identification for tax purposes.

Though some individuals might still be able to submit a return without a TFN, it could result in withholding rates that are higher than usual and complications in receiving tax rebates or refunds. Moreover, not having a TFN could lead to administrative challenges rather than outright barring someone from filing a tax return. Therefore, it is important to obtain a TFN to avoid these complications and potential fines related to tax obligations.
