Filing

Thanks for your reply.

My 2019 earnings in Canada were Gross $11,000  and $1200 tax . In Australia my earnings for 2019 were $5500 gross $772 tax . From declaring world income i don't understand why i would have to pay another $1000 tax. If i say no to world income there is a $1000 refund. Can it change that much just by saying yes to world income? I did not enter any mount  in any of the income boxes and it changes to tax owing soon as the Yes box is checked for "Do you have any income from outside Canada".

This is a very basic tax filing and all taxes were taken at source at the correct amount and there are no other investments, RRSP's  or other credits to claim.  Thanks  for any help with all this.
