My divorce decree says I owe her 20% of my net income. I called my state's Child Support Services, and they said I'm doing everything the way I need to be. I have receipts for money that I have paid her, I send her money every month, even if it's not an amount that she wants, it's 20% of what I earned. They also said she does not get 20% of what my business brings in, she gets 20% of what I take out, after I set aside 35% for Federal, Sate, Local and Self-Employment taxes.
