1) There Are No Restrictions Preventing a Tax Break
When you defer a portion of your salary into a traditional 401(k), the amount deferred will reduce your taxable income dollar-for-dollar. This is true regardless of how much income you (and your spouse, if applicable) have. In contrast, contributions to a traditional IRA are generally entitled to a tax deduction as well, but if your income is above certain limits and you (and/or your spouse, if applicable) are an active participant in an employer-sponsored retirement plan, then that deduction can be reduced or eliminated. Thus, in some scenarios, a contribution to a traditional IRA won’t help you reduce your current tax bill.
