Alimony received is taxable income. Alimony paid is deductible. Child support is not taxable income and is not deductible. However, it counts as support in determining who gets to claim the child(ren) as dependents. Therefore, if your arrangement with your ex is that she pays you $486 and the rest offsets each other, then you must report $1500 of income and can consider $1014 as part of your support paid.
