Fringe Benefits Tax Breakdown & Calculations
1. The Australian Fringe Benefits Tax Framework (2026–27)
Fringe Benefits Tax is governed by the Fringe Benefits Tax Assessment Act 1986.
Employers pay FBT at the flat rate of 47% on the grossed-up value of non-cash benefits provided to employees, ensuring tax neutrality with cash salaries.
2. Fringe Benefit Category & FBT Payable Benchmarks
| Fringe Benefit Category | Taxable Value | Gross-Up Type | Grossed-Up Value | FBT Payable (47%) |
|---|---|---|---|---|
| Company Car (Statutory Formula) | $10,000 Taxable Value | Type 1 (2.0802 Rate) | $20,802 Grossed-Up | $9,776.94 FBT Payable |
| Expense Payment (GST Claimable) | $5,000 Taxable Value | Type 1 (2.0802 Rate) | $10,401 Grossed-Up | $4,888.47 FBT Payable |
| Expense Payment (No GST Credit) | $5,000 Taxable Value | Type 2 (1.8868 Rate) | $9,434 Grossed-Up | $4,433.98 FBT Payable |
| Electric Vehicle (Novated Lease) | $12,000 Lease Value | Exempt (0% FBT) | $0 Grossed-Up | $0.00 FBT Payable |
3. The Mathematics of FBT Gross-Up Multipliers
Total FBT Liability (FBT_tax) for net taxable value (V_tax) and Type 1 / Type 2 multiplier (M_gross) is:
Example Type 1 Calculation ($10,000 Car Taxable Value):
- Grossed-Up Taxable Value: $10,000 × 2.0802 = $20,802.00.
- Total FBT Payable @ 47%: $20,802 × 47% = $9,776.94 FBT tax.
- If employee pays $10,000 after-tax contribution: Net FBT Payable = $0.00.

Frequently Asked Questions (FAQ)
What is Fringe Benefits Tax (FBT) and who pays it in Australia?
Fringe Benefits Tax (FBT) is a tax paid by employers in Australia on certain benefits provided to employees (or their family members) in addition to, or as part of, their salary package. FBT is separate from income tax and is calculated at the top marginal tax rate of 47%.
What is the difference between Type 1 and Type 2 FBT Gross-Up Rates?
Type 1 Gross-Up Rate (2.0802) applies when the employer is entitled to claim a GST input tax credit on the benefit provided. Type 2 Gross-Up Rate (1.8868) applies when the employer is NOT entitled to claim a GST credit.
How does the Electric Vehicle (EV) FBT Exemption work for employers and employees?
Zero or low-emission vehicles (battery electric, hydrogen fuel cell, or plug-in hybrids below $91,387 luxury car tax threshold) provided for private use are 100% exempt from FBT, delivering massive tax savings on novated leases.
How do Employee Contributions reduce or eliminate FBT liabilities?
An employee can make an after-tax post-tax contribution toward the cost of a fringe benefit (e.g. paying for car fuel or lease payments after tax). This directly reduces the taxable value of the benefit dollar-for-dollar, reducing FBT payable to $0.
What is the "Otherwise Deductible Rule" in FBT calculations?
The Otherwise Deductible Rule reduces the taxable value of a fringe benefit if the employee would have been able to claim a direct income tax deduction for the expense had they paid for it themselves (e.g. work laptop or self-education course).
