For individuals trying to find child support tax information, there are a few important things to understand. First of all, child support payments are not taxable for the custodial parent who receives them, and they are not tax-deductible for the non-custodial parent who pays them. One great way of finding child support tax information is to contact a child support attorney. Attorneys know the child support laws and how they work. They can inform their clients of any tax information they need to know, such as how to document the child support payments, and other pertinent information. Child support attorneys are a valuable resource to both custodial and non-custodial parents alike. More information can also be obtained from the Child Support Enforcement Agency. Each state has a branch of this agency and one can contact them through the Department of Revenue or the Department of Human Services in their own county.
