If you are in charge of payroll in the office then the below ATO link can help you identify the reasonable travel and overtime meal allowance for the 2017-2018 income year. It details the different allowance rates for meals, accommodation and incidentals whilst travelling for work purposes as well as the allowance rate for meals whilst working overtime. If you have any questions or are unsure how to calculate your employees travel allowances then please contact my office.
