My job offers a 401k, but I don't contribute to it (because it doesn't have a match). Instead, I would rather contribute to an IRA where I can control what I invest in exactly. Here's what the IRS says:
If either you or your spouse was covered by an employer retirement plan, you may be entitled to only a partial (reduced) deduction or no deduction at all, depending on your income and your filing status. Your deduction begins to decrease (phase out) when your income rises above a certain amount and is eliminated altogether when it reaches a higher amount. These amounts vary depending on your filing status.
Let's say I make enough that I wouldn't be entitled to any IRA deduction while contributing to both a 401k and IRA.
Am I ineligible to deduct IRA contributions because my company offers a 401k, even though I don't contribute to it?
