For fleets, LCT matters twice. It adds cost to vehicles above the threshold, and the fuel-efficient threshold ($91,387 for 2025-26, $91,661 for 2026-27) is the eligibility test for the FBT electric car exemption: if LCT was ever payable on the car, the exemption is off the table.
Thresholds are indexed every 1 July, so the year the car was first held matters.
