What is the form for my daughter to sign giving me permission to claim her children? They all lived with me in 2024 and she did not have a job.

There is no form for her to sign.   If all of them lived with you and you provided their support you can claim your grandchildren as dependents, and if your daughter had less than $5050 of income (not counting any Social Security) you can also claim her as a dependent.  Enter your dependents in MY INFO.

To claim a grandchild as your dependent

When you enter the child’s name in My Info, you will be asked “What’s your relationship to  [child’s name]?”  

           Choose “another person”

            a drop down menu will appear that lets you choose grandchild

WHO CAN I CLAIM AS A DEPENDENT?

You can claim a child, relative, friend, or fiancé (etc.) as a dependent on your 2024 taxes as long as they meet the following requirements:

Qualifying child

• They're related to you.
• They aren't claimed as a dependent by someone else.
• They're a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
• They aren’t filing a joint return with their spouse.
• They're under the age of 19 (or 24 for full-time students).
• No age limit for permanently and totally disabled children.
• They lived with you for more than half the year (exceptions apply).
• They didn't provide more than half of their own support for the year.

Qualifying relative

• They don't have to be related to you (despite the name).
• They aren't claimed as a dependent by someone else.
• They're a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
• They aren’t filing a joint return with their spouse.
• They lived with you the entire year (exceptions apply).
• They made less than $5050 in 2024 (not counting Social Security)
• You provided more than half of their financial support.

When you add someone as a dependent, we'll ask a series of questions to make sure you can claim them. There may be other tax benefits you can get when you claim a dependent.

You don't need her to sign a form releasing dependent exemptions if the children lived with you. The form for releasing dependent exemptions is to resolve issues between divorced or separated parents only. 

If your daughter lived with you as well, review the “tie breaker rules,” which are found in IRS Publication 501 if she had income. If she didn't have income, as @xmasbaby0 pointed out, you may be able to claim her as a dependent as well. These rules establish income, parentage, and residency requirements for claiming a child:

To determine which person can treat the child as a qualifying child to claim these five tax benefits, the following tiebreaker rules apply. For purposes of these tiebreaker rules, the term “parent” means a biological or adoptive parent of an individual. It does not include a stepparent or foster parent unless that person has adopted the individual.

• If only one of the persons is the child's parent, the child is treated as the qualifying child of the parent.
• If the parents file a joint return together and can claim the child as a qualifying child, the child is treated as the qualifying child of the parents.
• If the parents don't file a joint return together but both parents claim the child as a qualifying child, the IRS will treat the child as the qualifying child of the parent with whom the child lived for the longer period of time during the year. If the child lived with each parent for the same amount of time, the IRS will treat the child as the qualifying child of the parent who had the higher AGI for the year.
• If no parent can claim the child as a qualifying child, the child is treated as the qualifying child of the person who had the highest AGI for the year.
• If a parent can claim the child as a qualifying child but no parent does so claim the child, the child is treated as the qualifying child of the person who had the highest AGI for the year, but only if that person's AGI is higher than the highest AGI of any of the child's parents who can claim the child.

Subject to these tiebreaker rules, you and the other person may be able to choose which of you claims the child as a qualifying child.
