Check whether the Saver's Credit applies to your IRA or 401(k)
Added
If you are 18 or older, not a dependent, and not a student, eligible contributions to a traditional or Roth IRA, 401(k) or similar workplace plan may qualify for the Retirement Savings Contributions Credit. The credit rate is 50%, 20% or 10% depending on your adjusted gross income and filing status. Use Form 8880 to figure it, and check the IRS page for this year's AGI chart.
The result
Result: IRS: credit is 50%, 20% or 10% of eligible contributions; the maximum contribution that may qualify is $2,000 ($4,000 if married filing jointly), so the maximum credit is $1,000 ($2,000 if married filing jointly). Rollovers do not qualify.
