Why the childless version is different
The credit was built to reward work, and it is largest for workers with qualifying children. Workers without children get a much smaller version with tighter limits. You still need earned income, which means wages, tips or net self-employment income. Interest, unemployment and most benefits do not count as earned income.
The credit is refundable. If it is bigger than the tax you owe, the rest comes back as a refund, which is why a missed credit is a missed refund.
The age rule
For filers with no qualifying children, the IRS sets a minimum and maximum age. At the time of writing the range is 25 through 64, measured by your age at the end of the tax year. A 22-year-old who earned $15,000 will generally not qualify for the childless credit, even though the same income would qualify an older worker.
If you are married filing jointly, the age rule is applied to the couple, and the IRS instructions explain whose age counts. Check the current instructions, because Congress has changed this age range before.
Other tests you must pass
You need a valid Social Security number that allows you to work, and your filing status cannot be one the credit excludes. You cannot be claimed as someone else's dependent, and you cannot be the qualifying child of another person. Foreign earned income that you exclude does not count.
There is also an investment income limit that changes every year. A little interest is fine, but large dividends or capital gains can disqualify you for that year.
Income limits and the table
The maximum income for the credit depends on your filing status and how many children you have. The IRS publishes the numbers in an EIC table, and the credit is taken from the row for your income. Do not estimate it from a percentage, because the amount rises, flattens and then falls as income grows.
If your income is just above the cutoff, check each line that feeds the figure. A deduction you forgot, such as half of self-employment tax, can lower your adjusted gross income into range.
When you think you qualify and the software says no
The most common causes are an age outside the range, a missing or non-work Social Security number, filing as married filing separately, or a dependent box ticked by mistake. Fix the facts if they are wrong. If they are right, the result is correct even if it is disappointing.
MCC Tax 1040 adds the credit when your answers qualify and explains it in a note when it does not, so you can see which rule applied. Always check the result against the IRS EIC table.
If you were under 25 or the credit was denied
If the IRS denies a credit, it may require a form to show you meet the rules before you can claim it again. Keep records that support your answers, such as proof of earned income and your Social Security card. If you got a notice, read it fully and reply by the date shown.
Common questions
Can a full-time student claim the childless credit?
A student can, if they meet the age, income and other tests and are not a dependent. Many students are dependents or under the minimum age, so most do not.
Does unemployment count as earned income?
No. Earned income is pay for work and net self-employment income. Unemployment benefits do not count.
Where do I claim it?
On the federal Form 1040 line for the earned income credit. Some states, including New Jersey and New York, offer their own credit based on the federal one.
