I started doing 2 jobs and the new job has become my primary income.
I ticked yes to claim the tax-free threshold from the new primary full-time job for the Tax File Declaration Form.
In the mean time, the old job (non-primary job now) has been changed to casual contract.
Questions:
What should I do to manage my tax returns?
Do I need to advise my non-primary employer for me to update the Tax File Declaration Form or other forms to not claim the tax-free threshold from them?
