If you've ever wondered why one child qualifies for a larger tax credit than another, you're not alone.
"Why did I only get a $500 credit for my dependent instead of the full Child Tax Credit?"
The answer usually comes down to two different tax benefits: the Child Tax Credit (CTC) and the Credit for Other Dependents (ODC). While both can help lower your tax bill, they have different rules and different dollar amounts.
The Child Tax Credit is designed for younger qualifying children.
For the 2025 and 2026 tax years under current law, a qualifying child generally must:
- Be under age 17 at the end of the tax year.
- Be your son, daughter, stepchild, foster child, sibling, or another qualifying relative.
- Have lived with you for more than half the year.
- Not have provided more than half of their own support.
- Have a valid Social Security number that is valid for employment.
- Be claimed as your dependent.
The Child Tax Credit can be worth up to $2,000 per qualifying child, and a portion of that amount may be refundable, meaning you could receive money back even if you owe little or no federal income tax.
But what happens if your dependent doesn't meet those requirements? That's where the Credit for Other Dependents comes in.
The Credit for Other Dependents is worth up to $500 per qualifying dependent and applies to people who don't qualify for the Child Tax Credit.
This might include:
- Children who are age 17 or older.
- Elderly parents you support.
- Certain relatives living with you.
- Dependents who have an ITIN or ATIN instead of a qualifying Social Security number, provided they otherwise meet the dependency rules.
Unlike the Child Tax Credit, the Credit for Other Dependents is nonrefundable. This means it can reduce your tax bill to zero, but it won't create a refund by itself.
A common example we see is a family with two children. Their 10-year-old qualifies for the Child Tax Credit, while their 18-year-old high school senior may qualify for the Credit for Other Dependents. The family can potentially claim both credits on the same return.
It's also important to remember that simply having a child or relative living with you doesn't automatically qualify you for either credit.
The IRS has rules regarding relationship, residency, financial support, citizenship or residency status, and identification requirements. In divorce situations or shared custody arrangements, only one taxpayer can generally claim the qualifying child for these credits in a given year.
Another point of confusion is that these credits are separate from education credits, childcare expenses, or Head of Household filing status. You may qualify for several tax benefits at the same time, but each has its own set of rules.
The good news is that if someone qualifies as your dependent, there's a good chance there's some tax benefit available. The challenge is determining which credit applies and making sure the proper documentation is in place before filing.
If you're supporting a child who's turned 17, helping an aging parent, caring for a grandchild, or navigating a shared custody arrangement, it's worth having a tax professional review your situation. A small difference in eligibility can mean a significant difference in your tax savings.
