Child Tax Credit, EITC and head of household: a family tax guide for 2026 returns.

For many families, the tax return is the biggest single payment of the year. Most of that money comes from a handful of family credits, and each one has its own rules about who qualifies, who can claim a child, and when the refund arrives. This guide explains the credits that matter most for families filing their 2026 returns in early 2027, in plain English.

Credits versus deductions

A deduction lowers the income you are taxed on. A credit lowers the tax itself, dollar for dollar. Some credits are refundable, which means that if the credit is larger than your tax, the IRS pays you the difference as part of your refund. That is why a family with modest income and no tax due can still receive a significant refund.

The Child Tax Credit

For 2026, the Child Tax Credit is worth up to $2,200 for each qualifying child under 17 at the end of the year. Up to $1,700 per child is refundable as the Additional Child Tax Credit for families who do not owe enough tax to use the full credit. The refundable part depends on earned income, so a family needs some earnings from work to receive it.

A child generally qualifies if they:

• Were under 17 on December 31, 2026.
• Are your son, daughter, stepchild, foster child, sibling, step-sibling, or a descendant of one of them, such as a grandchild, niece or nephew.
• Lived with you for more than half the year (with exceptions for birth, death and temporary absences such as school).
• Did not provide more than half of their own support.
• Have a Social Security number valid for employment, issued before the due date of the return.
• Are claimed as your dependent and are a US citizen, national or resident alien.

Under the 2025 tax law, the person claiming the credit must also have a valid Social Security number; for married couples filing jointly, at least one spouse must. If a parent files with an ITIN, ask us how this affects your family, because the rules are specific.

The credit begins to phase out at higher incomes: $200,000 of modified adjusted gross income for most filers and $400,000 for married couples filing jointly.

The Earned Income Tax Credit (EITC)

The EITC is a refundable credit for working people with low to moderate income. It can be worth a great deal: for 2026, the maximum is $8,231 for a family with three or more qualifying children. Workers without children can also qualify for a smaller amount if they are between 25 and 64.

The EITC depends on three things: your earned income, your filing status and the number of qualifying children. It rises as you earn more, levels off, and then phases out. There is also a limit on investment income. Because the calculation is precise, small details such as which parent the children lived with can change the amount by thousands of dollars.

The IRS reviews EITC claims closely. As a paid preparer we are required to ask questions and keep records showing how we confirmed your eligibility, so expect us to ask where each child lived and for how long. It protects you if the IRS asks later. The IRS's own EITC page has an eligibility assistant.

When EITC and Child Tax Credit refunds arrive

By law, the IRS cannot issue refunds that include the EITC or the Additional Child Tax Credit before mid-February, even if you file on the first day of the season. The IRS has said in recent years that most of these refunds arrive by early March for people who file early, choose direct deposit and have no problems with their return.

Filing early still helps: your return is in the queue, errors are found sooner, and you are less likely to be caught by identity theft, where someone else files using your Social Security number first. You can track progress at Where's My Refund?; our article how long does a tax refund take? explains the stages.

Head of household: the filing status families often miss

If you are unmarried and pay more than half the cost of keeping up a home for a qualifying person, such as your child, you may qualify as head of household. It has a larger standard deduction than single status ($24,150 compared with $16,100 for 2026) and wider tax brackets, which can mean a noticeably smaller tax bill.

• You must be unmarried, or considered unmarried, on the last day of the year. A married person who lived apart from their spouse for the last six months of the year and kept up a home for a child may count as unmarried.
• You must pay more than half the household costs: rent or mortgage, utilities, food eaten at home, property tax and insurance.
• Your qualifying person must generally live with you for more than half the year.

Claiming head of household when you do not qualify is one of the most common errors the IRS corrects, so we will ask about household costs and living arrangements.

Who claims the child when parents live apart?

Only one person can claim each child for the Child Tax Credit, the EITC and head of household. When parents are separated or divorced, the general rule is that the custodial parent, the one the child lived with for more nights during the year, has the right to claim the child.

The custodial parent can release the claim to the Child Tax Credit to the other parent by signing Form 8332, but the EITC and head of household stay with the parent the child actually lived with. A court order alone does not override the tax rules. If two people claim the same child, the IRS will apply tie-breaker rules and one of you will receive a letter, often with a refund held. Talk it through before either of you files.

Childcare and the Child and Dependent Care Credit

If you pay for childcare so that you, and your spouse if married, can work or look for work, you may qualify for the Child and Dependent Care Credit. It applies to care for children under 13 and certain dependents who cannot care for themselves. The 2025 tax law expanded this credit starting in 2026, so families who did not benefit in the past may want to check again.

You will need the provider's name, address and tax identification number, which is their Social Security number or employer ID. Ask for it when you start paying the provider, not in April. If your employer offers a dependent care account, the amounts paid through it reduce what you can claim as a credit.

Other family items worth knowing

• New baby: a child born at any time in 2026, even December 31, can be claimed for the whole year. Apply for their Social Security card at the hospital.
• Students: the American Opportunity Credit can be worth up to $2,500 a year for the first four years of college, partly refundable. Bring Form 1098-T.
• Adoption: an adoption credit is available for qualifying adoption expenses.
• Marketplace insurance: if you had Marketplace coverage, Form 1095-A is required to reconcile the premium tax credit.
• Trump accounts: the 2025 law created new savings accounts for children, including a government contribution for some babies born from 2025 to 2028. Ask us if you have a newborn.

Avoid these refund delays

• A Social Security number or name that does not match Social Security records.
• Two people claiming the same child.
• Missing childcare provider details.
• A missing Form 1095-A for Marketplace insurance.
• Bank details typed incorrectly. Bring a voided check or a screenshot from your banking app.
• Filing before you have every W-2. A corrected return later takes months.
