I didnt file my 2016 taxes on time. So I did it this year using the turbo tax 2016... I'm wondering if it will effect my 2017 tax return. Should I wait for 2016 taxes to be filed (it's already been sent through e-file) before I submit my 2017 tax return? I'm wondering if it is going to effect my return.
It depends on what you have on
your return. If you have something like carry forwards (Tuition, losses), RRSP
contributions or something else that affects multiples years, then what you did
in 2016 will affect your 2017 return.
If you do file your 2017 return and then find out you need to make a change based on your 2016 return, you can always make an adjustment.
