Understanding the FBT Calculation
Fringe Benefits Tax is designed to ensure that the tax paid on benefits is equivalent to the tax that would have been paid on a cash salary. This is achieved through a "gross-up" calculation.
- Determine the Taxable Value: This is the value of the benefit provided to the employee. For cars, this is often calculated using the statutory formula (20% of the car's base value).
- Gross-Up the Value: The taxable value is multiplied by a gross-up rate to reflect the pre-tax salary that would be needed to purchase that benefit. The rate depends on whether GST was paid on the benefit.
- Apply the FBT Rate: The grossed-up value is multiplied by the FBT rate (currently 47%) to determine the tax payable by the employer.
