Allowances
The payslip may include both taxable or non-taxable allowances. The type of allowance may range based on what is agreed in your contract, such as hourly allowances, performance bonuses, car allowance, and many more.
If you have any questions on any particular allowance, it is generally advised to review your contract or contact your manager.
Car Allowance
As per CFR here: Fringe Benefits Tax Guide, the Car Allowance may be paid to the employee for the use of their own car. Although the full portion of Car Allowance is noted under the Earnings, do note that for up to €1,170, only 50% of the allowance is taxed.
