Without having a complete question, I am going to cover a couple of possible questions
Summer camp will not create an issue for claiming your child as a dependent. The camp would be considered a temporary absence for the residency test. You will consider the time spent at camp as time lived at home with you. See the following from IRS Publication 501:
Temporary absences. Your child is considered to have lived with you during periods of time when one of you, or both, are temporarily absent due to special circumstances such as:
Military service, or
- Detention in a juvenile facility.
You most likely cannot use the camp expenses for the child and dependent care credit. See the following from IRS Publication 503:
Camp . The cost of sending your child to an overnight camp isn't considered a work-related expense.
The cost of sending your child to a day camp may be a work-related expense, even if the camp specializes in a particular activity, such as computers or soccer.
