I switched to a job in 2012 which didn't offer a retirement plan in October, 2012. Prior to this job, I was covered with an IRA account from my previous employer. I will be filing the returns with my spouse who is covered with a retirement plan through her work.
I read that one can claim a deduction when no retirement plan is offered at work. I would like to contribute the maximum amount towards a Traditional IRA account that I set up with someone like Fidelity. Will my contribution be deductible for the 2012 tax return? Additionally, how much amount can I contribute for a maximum deduction?
