The 2014 contribution limits will remain the same as they are for 2013. You can contribute as much as $17,500 to a 401(k), 403(b), 457 or the federal government’s Thrift Savings Plan, plus as much as $5,500 more in catch-up contributions if you’re 50 or older in 2014. And the annual contribution limit for traditional and Roth IRAs remains at $5,500 in 2014, plus as much as $1,000 more if you're 50 or older. The income limits determining who can contribute to Roth IRAs are increasing very slightly. You can contribute to a Roth IRA in 2014 only if your adjusted gross income is less than $129,000 if single or $191,000 if married filing jointly.

To qualify for the credit, your 2014 adjusted gross income must be less than $60,000 for married couples filing jointly, less than $45,000 for heads of household, and less than $30,000 for singles or married individuals filing separately.
