Earlier quoted context omitted.
I'm confused. Income in an IRA isn't taxed, so that's not relevant for taxes. If you had post-tax investments then yes it's more complicated, but that has nothing to do with IRA/401k retirement savings?
I assume they meant a Roth IRA, which does tax deposits.
Anyways, whether it was from the brokerage I opened or the IRA, I had a class of income that would have made me need to pay to file, even though my total income was below 65k.
Another thing was foreign taxes paid (because some funds in one of your indexes are international). But they don't let you just say "listen, I'd rather skip the credit for those two whole dollars in taxes and not pay 50 dollars to file"
