How Fringe Benefit Tax (FBT) is calculated
FBT is paid by employers on non-cash benefits given to staff (e.g. company cars, low-interest loans, gifts). The single-rate calculation uses 63.93% of the grossed-up taxable value.
- 1
Determine taxable value of benefit
Taxable_value = market_value − employee_contribution
For motor vehicles, use the schedular method or cost basis.
- 2
Apply single FBT rate (63.93%)
FBT_payable = taxable_value × 63.93%
Single rate option — simpler but higher than employee marginal rates.
- 3
Or use attributed multi-rate method
FBT = sum(benefit × rate_for_employee_bracket)
Multi-rate matches each employee's marginal rate — lower FBT for low earners.
- 4
Quarterly returns due
Quarter ends: 30 Jun, 30 Sep, 31 Dec, 31 Mar
Annual or income-year FBT returns also available for small employers.
Worked example
Inputs: Company car benefit valued at $8,000/year
Result: Single-rate FBT = $8,000 × 63.93% = $5,114.40/yr.

How this calculator works
Attributed benefits (specific to one employee) are taxed at the rate matching the employee's marginal rate (49.25%, 43%, 32.5%, or 11.73%). Non-attributed pool benefits are taxed at 49.25%. The most common benefit is a motor vehicle — calculated at 20% of cost price (or 36% of OMV for vehicles over 3 months old) per year.
FBT Rates for Attributed Benefits
| Employee income up to $12,530 | 11.73% |
| Employee income $12,531 – $40,580 | 21.21% |
| Employee income $40,581 – $55,980 | 42.86% |
| Employee income $55,981 – $103,500 | 49.25% |
| Employee income $103,501+ | 63.93% |
| Non-attributed (pool) benefits | 49.25% |
FBT is paid by the employer, not the employee. Rates are the FBT equivalent of the employee's marginal income tax rate.
Motor Vehicle FBT
| Annual taxable value | 20% of cost price per year |
| Alternative (OMV method) | 36% of open market value for vehicles held 3+ months |
| Employer pays FBT on this value | At applicable attributed rate |
Worked Examples
Company car with cost price $40,000, employee income over $55,981
Annual FBT value $8,000. Employer pays FBT at 49.25% = $3,940.
- Vehicle cost price: $40,000
- Annual taxable value: $40,000 × 20% = $8,000
- Employee income over $55,981 → attributed FBT rate 49.25%
- FBT payable by employer: $8,000 × 49.25% = $3,940 per year
- FBT is paid quarterly or annually by the employer
Employer-paid health insurance $2,400/year for employee earning $90,000
Attributed benefit taxed at 49.25%. Employer pays $1,182 FBT.
- Health insurance premium: $2,400/year
- Employee income $90,000 → attributed FBT rate 49.25%
- FBT payable: $2,400 × 49.25% = $1,182
- Total cost to employer: $2,400 + $1,182 = $3,582
