No, it is not compulsory, but it is recommended if you only have ONE job. This means you will get more in your pocket with each pay but should still be taxed the appropriate amount.
If you have TWO or more jobs, it is recommended that you claim the tax-free threshold on the highest paying job and claim the no-tax-free threshold with any additional jobs. This means only one employer is accounting for that $18,200 of tax-free income and you shouldn’t end up with a bill at tax time. *

*Disclaimer: Even when using this method, some taxpayers may be subject to paying tax after lodging their tax return as individual circumstances influence tax results.
