How Fringe Benefits Tax works in Australia

Fringe Benefits Tax (FBT) is a tax paid by employers on non-cash benefits provided to employees or their associates. The employer pays FBT, not the employee. The rate is 47%, equivalent to the top marginal income tax rate plus the Medicare levy. That rate applies to the grossed-up taxable value of the benefit, not the face value, which makes the effective cost higher than most employers expect.

The FBT year runs from 1 April to 31 March, separate from the income tax year. FBT returns are due by 21 May (or 25 June if lodged by a tax agent). Quarterly FBT instalments apply to businesses with annual FBT liabilities above AU$3,000.

Type 1 vs Type 2 gross-up

The gross-up converts the taxable value of a benefit into a pre-tax equivalent. Two rates apply depending on whether the employer can claim a GST credit on the benefit:

• Type 1 (GST credit available): gross-up rate 2.0802 for 2025-26. Applies to benefits like car leases, gym memberships, and meal entertainment from GST-registered suppliers.
• Type 2 (no GST credit): gross-up rate 1.8868 for 2025-26. Applies to benefits like residential rent, exempt financial services, and some insurance premiums.

The formula: FBT payable = taxable value × gross-up rate × 47%. A Type 1 benefit with a taxable value of AU$5,000 produces FBT of AU$5,000 × 2.0802 × 0.47 = AU$4,889. The employer pays nearly AU$5,000 in tax on a AU$5,000 benefit. This is why FBT planning matters.

Worked example: company car, statutory method

A Brisbane engineering firm provides a car to its operations manager. The car cost AU$55,000 (GST-inclusive) and was available for the full FBT year (365 days). The employee made no contributions.

• Taxable value (statutory method): AU$55,000 × 20% × (365/365) = AU$11,000
• Gross-up (Type 1, GST credit available): AU$11,000 × 2.0802 = AU$22,882
• FBT payable: AU$22,882 × 47% = AU$10,755

The employer pays AU$10,755 in FBT for providing a AU$55,000 car. If the employee contributes AU$3,000 from after-tax income, the taxable value drops to AU$8,000 and FBT falls to AU$7,822. Employee contributions are the most direct way to reduce car FBT.

Operating cost method vs statutory method

The statutory method values the car at a flat 20% of cost regardless of how much private use occurs. The operating cost method uses actual running costs (fuel, insurance, registration, depreciation, maintenance) multiplied by the private-use percentage determined from a logbook.

If the car is used 80% for business (verified by a 12-week logbook), only 20% of operating costs are taxable. For a car with AU$18,000 in annual running costs, the taxable value under the operating cost method is AU$3,600, compared to AU$11,000 under the statutory method. The operating cost method requires more record-keeping but produces significantly lower FBT when business use is high.

The logbook must cover a continuous 12-week period and is valid for five years provided the pattern of use does not change significantly. If your employees use company cars primarily for work, the operating cost method is almost always cheaper.

Common FBT exemptions and concessions

• Minor benefits exemption: Benefits with a notional taxable value under AU$300 per occasion that are also infrequent and irregular are exempt. But "infrequent" is assessed per employee across the full FBT year. Quarterly team dinners for the same employee are not infrequent.
• Work-related items: Portable electronic devices (one per year), tools of trade, protective clothing, and briefcases are exempt when used primarily for work.
• Car parking: Exempt if the market value of a nearby commercial parking station is below the ATO threshold (AU$10.40/day for 2025-26) or if the employer is a small business (turnover under AU$10 million) that provides car parking on their own premises.
• Exempt employers: Public benevolent institutions, health promotion charities, and some hospitals have FBT exemptions or caps that allow them to offer salary-packaged benefits without full FBT liability.

FBT and expense reimbursements

Expense reimbursements can create FBT liability if the reimbursed expense is private rather than business-related. A meal with clients may or may not be FBT-liable depending on who attended and whether the event was primarily business or entertainment. The challenge for AP teams is that expense approval processes rarely capture the information needed to determine FBT treatment at the time the claim is submitted.

Under the actual method for meal entertainment, the employer must know who attended, their relationship to the business, and the business purpose. If attendee records are not captured at the point of approval, the finance team must reconstruct this information at FBT year-end, which is often impossible for entertainment expenses from nine months earlier. Structured approval workflows that require this information before the expense is approved solve the data capture problem at source.

Frequently asked questions

What is the difference between Type 1 and Type 2 gross-up?

Type 1 applies when the employer can claim a GST credit on the benefit (gross-up rate 2.0802 for 2025-26). Type 2 applies when no GST credit is available (1.8868). The higher Type 1 rate accounts for the GST credit the employer receives, ensuring the overall tax treatment is equivalent to paying the benefit as salary.

How is a car fringe benefit calculated?

Under the statutory method: car cost × 20% × (days available / 365), minus any employee contributions from after-tax income. Under the operating cost method: total running costs × private-use percentage from a valid logbook. The operating cost method typically produces lower FBT when business use exceeds 60-70%.

What FBT exemptions are available?

Minor benefits under AU$300 per occasion (if infrequent and irregular), work-related items like laptops and tools of trade, car parking below the ATO threshold, and benefits provided by exempt employers such as public benevolent institutions. The minor benefits exemption is the most commonly used but also the most commonly misapplied.

When is the FBT return due?

21 May each year, covering the FBT year from 1 April to 31 March. If lodged through a tax agent, the due date extends to 25 June. Businesses with FBT liabilities above AU$3,000 must also pay quarterly instalments.
