Illinois Grandparent Caregiver Tax Benefits: CTC, EITC, and Claiming a Grandchild

Tax Credits You May Be Missing

Grandparents and relatives raising children in Illinois often don't realize they may qualify for the same federal tax credits that parents claim. The Child Tax Credit, Earned Income Tax Credit, and Illinois dependent exemption allowance can put thousands of dollars back into a kinship household — money that matters when you're stretching a retirement check to cover a growing child.

These credits are federal, but living in Illinois adds a few state-level considerations too. Here's what you need to know.

Claiming a Grandchild as a Tax Dependent

Before any credits come into play, you need to establish that the grandchild qualifies as your tax dependent under IRS rules. The requirements under IRC Section 152 for a "qualifying child" are:

• Relationship: A grandchild, niece, nephew, or other descendant of a sibling counts. So do foster children placed by a court or authorized agency.
• Residency: The child must live with you for more than half the tax year (183+ days). Temporary absences for school, medical care, or vacation still count as living with you.
• Age: Under 19 at the end of the tax year, or under 24 if a full-time student, and younger than you (or your spouse if filing jointly); any age if permanently disabled.
• Support: The child cannot provide more than half of their own support.
• No joint return: The child doesn't file a joint return with a spouse, unless the return was filed only to claim a refund of withheld or estimated tax.

Notice what's not on this list: you don't need legal custody, guardianship, or adoption to claim a grandchild as a dependent. Physical residency for more than half the year is the key test.

The tiebreaker rule: If both you and the biological parent could claim the child, the parent generally has priority. If no parent can claim the child, the person with the highest adjusted gross income wins. If a parent can claim the child but does not, another relative may claim the child only if that relative's adjusted gross income is higher than the highest AGI of any parent who could claim the child.

Child Tax Credit

For tax year 2026, if the grandchild qualifies as your dependent, you may claim a Child Tax Credit of up to $2,200 per qualifying child under age 17. Up to $1,700 may be refundable through the Additional Child Tax Credit (ACTC); you need at least $2,500 in earned income to qualify for the ACTC.

The CTC is non-refundable and can reduce federal income tax owed. The refundable ACTC has a separate earned-income requirement, so a grandparent with no earned income may not receive a refund through that part of the credit.

Income phaseout: The credit begins to phase out at $200,000 AGI for single filers and $400,000 for married filing jointly — thresholds most kinship caregivers fall well under.

Earned Income Tax Credit

The EITC is designed for low-to-moderate income workers, and grandparents who are still employed (even part-time) may qualify if they're raising a grandchild.

You need earned income — wages, self-employment, or similar. Social Security, pensions, and TANF don't count as earned income. But if you're working even part-time while raising a grandchild, the EITC can be substantial:

• 1 qualifying child: up to $4,427 credit (2026)
• 2 qualifying children: up to $7,316
• 3+ qualifying children: up to $8,231

The qualifying child rules for EITC match the dependent rules above: the child must live with you more than half the year, be under 19 (or 24 if a student), and have a valid SSN.

Investment income limit: Your investment income must not exceed $12,200 for tax year 2026. Interest from a savings account usually doesn't push you over, but be aware if you have significant investment income.

Illinois State Tax Considerations

Illinois has a flat income tax (4.95%) and offers a state Earned Income Tax Credit (EITC), calculated as 20% of the federal EITC. Illinois also has a dependent exemption allowance; claiming a grandchild may qualify you to claim that allowance on your state return.

Illinois also offers a property tax credit equal to 5% of Illinois real estate tax paid on your principal residence. You must own the residence to claim it; the credit is not specific to caregiving.

How Tax Benefits Interact With Public Assistance

Receiving the TANF child-only grant doesn't affect your ability to claim these tax credits. TANF cash isn't taxable income and doesn't show up on your tax return.

Receiving a public assistance grant does not by itself establish tax dependency or credit eligibility; the child and caregiver must meet the tax rules for each claim.

However, be aware of two interactions:

• Claiming the child as a dependent and All Kids: If you claim the grandchild as a tax dependent, the MAGI household calculation for All Kids may change. In most kinship cases this doesn't matter because the child's own income is negligible, but if your income is near the 318% FPL threshold, check with your caseworker.
• EITC and SNAP: EITC refunds are not counted as income or resources for SNAP purposes for 12 months after receipt. Don't spend the refund immediately on something that would convert it into a countable resource beyond that 12-month window.

Getting Help Filing

The IRS Volunteer Income Tax Assistance (VITA) program offers free basic tax preparation to qualifying taxpayers. The IRS does not set a program-wide income limit; many sites generally focus on people who make about $70,244 or less, and individual sites may set their own limits. Find a VITA site at irs.gov/vita or call 1-800-906-9887.

AARP Tax-Aide is another free option for taxpayers over 50, regardless of AARP membership.

If your tax situation is straightforward — Social Security plus maybe a part-time job, one or two grandchildren — VITA can handle it and make sure you're claiming everything you're entitled to.

The Illinois kinship financial help guide covers how every benefit program interacts with your taxes and includes a document tracker so you have everything ready when tax season arrives.

Frequently Asked Questions

Can I claim my grandchild as a dependent if the biological parent is in prison?

Incarceration alone does not determine who may claim the child. Apply the residency and tiebreaker rules; if a parent and grandparent both qualify, the parent generally has priority. A tax preparer can review the facts before you claim the child for the dependent exemption, CTC, or EITC.

What if the child receives Social Security survivor benefits — does that count as the child's support?

Social Security benefits paid on behalf of a child count as support provided by the child only if the child (or someone else) uses those payments for the child's support. If you're using the survivor benefits to pay for the child's food, clothing, and housing, and those benefits don't exceed half of the child's total support, you can still claim the child. This gets nuanced — a VITA preparer can walk through the support worksheet with you.

Do I need a Social Security number for the grandchild to claim tax credits?

Yes. The child needs an SSN valid for employment to qualify for the CTC/ACTC or EITC, and the taxpayer must also meet each credit's SSN rules. An ITIN does not qualify the child for the CTC/ACTC. If the child doesn't have an SSN yet, apply at your local Social Security office; processing times can vary.
