Thanks for your question. Your ability to make tax-deductible IRA contributions depends on a couple of factors: first, whether or not you are covered by an employer-sponsored plan, and second, your income level.
For someone who is not covered by a company retirement plan, all IRA contributions are tax-deductible. But in your case, since you were contributing to a company 401(k) plan for part of the year, you are considered by the IRS to be covered for the whole year.
Because you are considered to be covered, you can only make tax-deductible IRA contributions if your income falls within the 2014 deductibility range. If your Modified Adjusted Gross Income is less than $60,000 if single, or $96,000 if married and filing jointly, you can make a fully deductible IRA contribution of up to $5,500 if you are under age 50 or $6,500 if you are age 50 or older. You can make a partially deductible IRA contribution if you make between $60,000 and $70,000 if single, or between $96,000 and $116,000 if married and filing jointly.
No matter what your income level, you can always make a non-deductible IRA contribution to make sure that you keep your retirement savings on track.
