The credit also is attractive to workers who are eligible to participate in a 401(k) plan but who earn just more than one of the saver's credit income limits. By signing up for a company-sponsored account, such workers could get under the earnings cap while simultaneously boosting the potential credit amount.
Take, for example, a married employee who is the sole earner in her family and who reports adjusted gross income of $37,000 on her joint tax return. She's already eligible for a 20 percent credit, but if she contributes $2,000 to her 401(k), she will knock her income down enough to take the maximum 50 percent credit.
Some other restrictions apply
In addition to the income limits, there are a few other restrictions on who can claim the saver's credit. A taxpayer who was younger than 18 last year, a full-time student or claimed as a dependent on another's tax return can't take the retirement savings break.
The saver's credit is also what the IRS calls nonrefundable. That means you can use it to reduce your tax bill to zero, but you can't take advantage of any excess credit amount to get a refund. So if you owe no taxes, the credit is of no use to you.
Still, even if you can't take full advantage of the credit, it's not too shabby of a break when you take into account the additional tax savings you get by contributing to a retirement account in the first place.
Just remember, the key to this credit is participation in retirement accounts. If you haven't opened a retirement account yet, or have one but haven't contributed for the 2013 tax year, you have until the April tax-filing deadline to open one and put in money. The deadline is the same for either a Roth or traditional IRA.
As for your 401(k), you're locked into your credit for the 2013 tax year based on the contributions you made last year. Make sure the W-2 you got from your company reflects the correct amount of all your pension contributions so you can get the maximum credit.
