Why is my EITC so low? Seven reasons the credit shrank

Why is my EITC so low: the quick diagnosis

Compare this year's return with last year's on four lines: earned income, AGI, filing status and the number of children on Schedule EIC. Almost every drop in the credit traces back to a change in one of those four. The checklist below lists the causes in a sensible order to check them.

Before assuming an error, check whether the credit was reduced by your own numbers or by the IRS. If the IRS changed it, you will get a notice that explains the adjustment; your software's figure and the refund you receive will then differ.

Your income moved into the phaseout

This is the most common reason the earned income credit is reduced. Once your income passes the phaseout start, $23,890 for 2026 with children ($31,160 joint), every extra dollar cuts the credit at a fixed rate. It feels like a penalty on a raise, and in effect it is one.

Example for 2026: a single parent of one child earning $24,000 gets about $4,409. The same parent earning $34,000 after a raise and some overtime gets about $2,811, a drop of roughly $1,600. The raise still leaves the household ahead, because $10,000 more pay costs about $1,600 of credit.

Overtime counts in full. Even if you deduct part of it under the no tax on overtime deduction, the IRS tells you to include all of it as earned income for the EITC.

Why did my EITC drop when a child turned 19?

A child stops being an EITC qualifying child at 19 unless they are a full-time student for at least five months of the year, in which case the limit is 24. A permanently and totally disabled child has no age limit. Losing one child can move you down a whole column in the table.

Example for 2026: a head of household earning $30,000 with two qualifying children gets about $6,029. If the older child turned 19 and did not attend school, the same return with one child gives about $3,451, roughly $2,580 less. If that was the last qualifying child, the parent would get nothing, because $30,000 is above the $19,540 no-child limit.

A child who moved out for more than half the year, or who now lives mostly with the other parent, drops off Schedule EIC in the same way. Check the residency and age tests in our EITC qualifications checklist.

EIC lower this year after marriage or a filing status change

Married couples must generally file jointly to claim the credit, and a joint return counts both spouses' income. The joint phaseout starts $7,270 higher, but a second paycheck often uses that up quickly.

Example for 2026: a single parent earning $25,000 with one child gets about $4,250. After marrying a partner who earns $20,000, the joint return shows $45,000 and the credit falls to about $2,215. Our marriage penalty page covers how marriage affects the rest of the return.

Switching to married filing separately does not fix this for most couples. It is allowed for the EITC only with a qualifying child and only if you lived apart from your spouse for the last six months of the year or are legally separated.

Non-work income raised your AGI

In the phaseout the IRS uses whichever is larger, AGI or earned income. Unemployment benefits, interest, a taxable retirement withdrawal, gambling winnings or taxable alimony received under an older divorce agreement all raise AGI without adding earned income.

Example for 2026: a single parent of one child with $20,000 of wages would normally get the full $4,427. With $8,000 of unemployment benefits added, AGI is $28,000 and the credit falls to about $3,770.

You earned less, or investment income crossed the limit

Low earnings in the phase-in

At the other end of the scale, a credit can be low because earned income is too small to reach the maximum. With one child you need $13,020 of 2026 earnings for the full $4,427; at $8,000 you get 34% of that, or $2,720. Fewer hours, time off work or a big business expense on Schedule C all lower earned income.

Investment income over $12,200

If your investment income is over $12,200 for 2026, the credit is not just reduced; it is gone. A one-time stock or property sale is the usual trigger. The 2025 limit was $11,950.

The IRS adjusted your claim

If the IRS reduced the credit because a child's SSN did not match its records or a child was claimed on another return, read the notice and respond by the date shown, with school, medical or lease records that show where the child lived. If the reduction was for anything other than a math or clerical error, you will need Form 8862 the next time you claim the credit.

What to do next

1. Put last year's and this year's Form 1040 side by side and compare earned income, AGI, filing status and the children listed on Schedule EIC.
2. Recalculate the credit with our earned income credit calculator using this year's figures.
3. If a child should still qualify, confirm the age, student status and months lived with you.
4. If the software is right, plan ahead: for 2027, check the new limits once announced, usually in October or November.
