    Frequently asked questions

    When is Type 1 vs Type 2 gross-up used?+
    Type 1 (factor 2.0802) applies when the employer was entitled to a GST input tax credit on the benefit. Type 2 (factor 1.8868) applies when no GST credit was available (e.g. GST-free or input-taxed supplies, or employer not registered for GST). FBTAA s 5B(1B)–(1C).
    Which car method usually wins?+
    Statutory formula is simple (20% flat × base value × days). Operating cost is paperwork-heavy but typically lower when business-use exceeds 50%. The choice is made annually per car.
    Do employee contributions reduce FBT?+
    Yes — after-tax contributions reduce the taxable value dollar-for-dollar before gross-up. Common in novated lease ECM arrangements to bring FBT to nil.
