<prompt> Human: Ok so Im a TN resident, I have no independent investment accounts per say. I do have a Roth IRA from vanguard and a 401 k through work... Are the returns from these accounts taxable in that I will need to file to state taxes?  <response>: Nope. You should get an end-of-year statement from Vanguard in the mail or electronically regarding the Roth, but its just for your records. Roth IRAs are post-tax, meaning youve already paid taxes on the youve invested.The 401k is pre-tax unless its a Roth 401k, and youll pay taxes on the in retirement as you take distributions.Also, its per se
