Fuel tax credit rates increased for fuels acquired from 10 November 2014. See the below link for further information.
If you have already lodged your BAS for fuel acquired after this date you will be entitled to more fuel tax credits and can claim these credits by amending your BAS. If you require assistance with this, please don’t hesitate to contact your accountant.
