I have a problem.. My children have to go to a private school here in Dubai at$22,000 per year because there are no public schools. Can I deduct this and how?

In general, tuition you pay for private school is not deductible if your children are attending kindergarten through 12th grade. However, aslongas your children also attend before- or after-school daycare programs, this portion of your expense might be deductible on your US return. In this case, you need to distinguish between what amount of your overall bill is tuition and what constitutes child care, the latter might qualify you for the Child Care Tax Credit. If you're married, both you and your spouse would have to work and earn income, unless one of you is disabled. Your children must be younger than 13, and they must enroll in the program to allow you and your spouse the freedom to work or look for a job. Or ou may claimThe additional child tax credit is a refundable tax credit for as much as $1k per eligible child for the credit, Your child must have a US social security number; Your child must be age 16 or younger as of December 31st of the tax year at hand.
