I have not contributed to an IRA for the past few years because our AGI is over 181K. I can participate in a traditional but I get no tax relief. If I participate now on a traditional and then later (when my AGI drops) I want to convert to ROTH, what would my taxes be? Zero since this money was already after tax? I am maxing my 401K. My company does not offer a ROTH 401K.
