My child attended a CYO day camp over the summer; is that taxable?

It may under certain circumstances be eligible for a Child Care Credit.

Please see this from the TurboTax Blog:

But then comes the blessed time of summer camp, when peace is restored for at least a few days. Although camp can be expensive, keep in mind that some of those expenses may be tax deductible. Here’s the scoop:

1. If you send the kids away to the mountains for a week, you won’t garner a tax deduction since overnight camps and programs don’t qualify. Summer day camps, however, qualify for the Child and Dependent Care Credit, as long as your child is under the age of 13 at the end of the tax year (no age limit if they are disabled) and you are sending your child to camp so you can work.
2. The Child and Dependent Care Credit enables you to work or go to school, so if you have a spouse at home to care for the children, then no deduction for camp. But if you are single, or you and your spouse both work, cha-ching, you’ll qualify for the tax credit.
3. Sending the kids into the backyard to camp out doesn’t qualify as camp. You have to make payment for camp to a real institution or person, and you must include their address and identifying the number on your tax return.
4. Your transportation costs to get the kids to the camp location won’t qualify for the credit. But if the cost of transportation to and from camp is included in the fees, and the camp picks up and delivers, sweet – that qualifies for the tax credit.
