Dont have much of an understanding of this matter, as have never done it myself. My little understanding is that you simply pay tax on the entire earnings for the second job as you cannot claim tax free threshold twice.
Looking at the ATO tax table if you
- earn $500 and claim Tax free threshold ($67 tax) = $433 net
- earn $400 and dont claim Tax free threshold ($87 tax) = $313 net
In two jobs earned $900 (tax $154) = $746 net
- earn $900 and claim tax free threshold ($182 tax) =$718 net
I know there is an error somewhere, but where and what is the easy way to figure this out???
