FBT Calculator

What This FBT Estimate Includes

Fringe benefits tax (FBT) is a tax employers pay on certain benefits they provide to employees or their associates. Use a car method to calculate one car’s taxable value, or enter Type 1 and Type 2 totals you have already worked out.

The result shows employer FBT for the selected year, which runs from 1 April to 31 March. Employee income tax, reportable fringe benefits and the employer’s full FBT return each require a separate calculation.

For a novated lease, use the relevant company car method to estimate the employer’s FBT on the car. Lease repayments, salary packaging and any change to the employee’s take-home pay are separate figures.

Company Car Taxable Value Methods

The statutory formula uses the car’s base value and days available for private use. The operating cost method uses the total cost of operating the car and the share of kilometres driven privately.

Statutory Formula

Multiply the FBT base value by 20% and by the days the car was used or available for private use. Divide by the number of days in the FBT year, then deduct eligible employee contributions. The taxable value stops at zero.

Enter the base value after applying any relevant adjustments. For an owned car, start with its original cost including dealer delivery and any applicable GST and luxury car tax. The ATO employer guide to car fringe benefits explains how the rules differ for owned and leased cars. Insurance, registration and stamp duty are excluded from the base value. Fitted non-business accessories can increase it.

The base value can fall by one-third from 1 April after the fourth anniversary of when you or your associate first owned or leased the car. The reduction excludes non-business accessories added after acquisition. For a pre-existing commitment to provide a car made before 7:30 pm AEST on 10 May 2011, check the transition rates in the ATO guide before using the flat rate.

Operating Cost Method

Subtract the business-use share from 100% to get the private-use share. Multiply total operating costs by that share, then deduct eligible employee contributions. If the difference is negative, the taxable value is zero.

Use invoices and expense records for the part of the FBT year you held the car to provide the benefit. Include running costs and applicable deemed depreciation and interest for an owned car, or lease payments for a leased car.

Use a representative logbook covering a continuous 12-week period in a logbook year and keep the required odometer readings. A business-use percentage needs records to support it. Without the required records, you cannot reduce the taxable value for business use.

An eligible contribution can include money the employee paid you from after-tax income or unreimbursed car expenses they paid directly. Keep payment records and relevant declarations, such as an employee declaration for fuel and oil costs.

Gross-Up and Estimated FBT

For the FBT year ending 31 March 2027, multiply Type 1 taxable value by 2.0802 and Type 2 taxable value by 1.8868. Add the two grossed-up amounts and multiply the total by the 47% FBT rate. ATO guidance on calculating FBT

Choose Type 1 for a car benefit if the employer is entitled to a goods and services tax (GST) credit for the benefit. Choose Type 2 when the employer has no GST-credit entitlement. In entered values mode, keep the two taxable totals in their own fields.

Exemption Checks and Supporting Records

The calculator shows the taxable estimate while you check exemption conditions. A vehicle label or a completed checklist alone cannot establish a claim.

The electric car exemption can apply to eligible battery electric or hydrogen fuel cell cars first held and used on or after 1 July 2022. The vehicle must meet the car capacity rules and be used by a current employee or their associate. Luxury car tax must never have been payable on its importation or sale.

From 1 April 2025, a plug-in hybrid car can qualify under the transitional rules if its use was already exempt and a financially binding commitment continued that private use. Check lease variations and any change of employer against the ATO electric car and work vehicle exemption guidance.

Some utes, vans and other work vehicles can qualify when private travel is limited to work-related travel and other use is minor, infrequent and irregular. Confirm the vehicle design and use against the ATO’s limited private use guideline. Some vehicles outside the FBT definition of a car need a residual benefit valuation.

Keep purchase or lease documents, evidence of first use and any invoices that establish the luxury car tax history. Retain odometer readings or trip records to support limited private use and keep any employee declarations the applicable treatment requires. An exempt electric car can still produce a reportable fringe benefits amount.

A Traceable FBT Worked Example

In the fictional example loaded above, a brokerage makes a car with a $48,750 base value available for 292 of 365 days in the FBT year ending 31 March 2027. The employee contributes $1,800 and the employer is entitled to a GST credit.

The statutory formula gives $7,800 before the contribution and $6,000 after it. The Type 1 factor gives a grossed-up total of $12,481. At 47%, estimated employer FBT is $5,866. The display rounds to whole dollars after calculating the amounts.

With entered values of $3,250 for Type 1 and $1,500 for Type 2, the two grossed-up amounts display as $6,761 and $2,830. Their grossed-up total displays as $9,591. The 47% rate gives $4,508 in estimated FBT.

For the same car, assume $15,260 in supported operating costs and 68% business use. The operating cost method gives a taxable value of $3,083 after the $1,800 contribution. With the Type 1 factor and the same tax rate, estimated FBT is $3,014.

Entering zero for both categories gives $0 FBT. In the car example, a contribution above $7,800 reduces taxable value to $0. An operating cost entry of 101% business use stops the calculation until the percentage is corrected.

Excel Formulas for the 2027 FBT Year

Enter 2027 in B1, the base value in B2, days available in B3 and the eligible contribution in B4. For the statutory example, enter 48750, 292 and 1800 in B2 to B4. The factors and rate below apply to the FBT year ending 31 March 2027.

For a Type 2 car benefit, put =0 in B7 and =B6 in B8. For the entered values example, put 3250 and 1500 in B7 and B8.

To model the operating cost method, put total operating costs in B2 and enter business use in B3 as a percentage, such as 75%. Keep the contribution in B4 and replace B6 with =MAX(0,B2*(1-B3)-B4). Format the final figures to show whole dollars.
