Currently, the sliding FBT scale rewards employer-provided cars that are driven further. However, this sliding scale will be replaced with a single 20% flat rate that applies regardless of the distance travelled.
The reform will only apply to vehicle contracts established after May 10, 2011 and will be phased in over a period of four years. The statutory rate for travelling over 40,000 kilometres a year will increase from 10 cents this year to 13 cents in 2012 and 17 cents in 2013, before being standardised across the board at 20 cents from 2014.
