Worried you’re missing part of your refund? Remember, the low and middle income tax offset isn’t a refund on its own – it’s used to offset (or reduce) the amount of tax you pay. The offset amount you may be entitled to is automatically applied and could range between $255-$1080, depending on things like your taxable income and how much tax you’ve paid.
If you are using a period (say 2 months in a year) from the log book to estimate the on-road and off-road usage percentage for heavy/light vehilces for calculating the fuel tax credit, can you use this percentage for a few years? How often does this percentage need to be reveiwed - I couldn't find anything on this?
for eg: for car fringe benefit you can use the same log book business percentage use for 5 years (assuming there is no major change in the pattern of use). Is there anything similar for fuel tax credits?
