Fringe benefit tax (FBT): Calculating fringe benefit tax

Short form alternate rate (formerly multi-rate) calculations

From 1 October 2010 personal tax rates have changed, so the higher FBT rates of 61% and 61.29% have reduced to 49.25%. The following information is using the rates from 1 October 2010 onwards. If you are calculating your FBT requirements for periods prior to 1 October 2010, you will need to use the previous rates.

Complete this calculation in your annual or income year return. Or, if you file on a quarterly basis, in the fourth or final quarter return (quarters 1 to 3 should be calculated using the single rate option of either 49.25% or 43%).

Classifying the benefits

Under this option you must still classify benefits as either:

  • attributed - all of these benefits are subject to the single rate of 49.25%, or
  • non-attributed - all of these benefits are subject to the single rate of 42.86% (or 49.25% if provided to major shareholder-employees).

Where non-attributed benefits are provided to shareholder-employees, two pools for non-attributed benefits may be necessary. This option may appeal to employers providing attributed and non-attributable benefits mainly to employees who earn more than $70,000 gross equivalent income.

Doing the calculation

To undertake the short form alternate rate calculation process, complete the FBT alternate rate calculation sheet - quarterly returns (IR417) as follows:

  1. in column 1 on separate lines enter attributed benefits and non-attributed benefits
  2. in column 9 enter the total amount of benefits that were attributed or non-attributed
  3. in column 10 enter the rate that you are using to calculate FBT payable
