I am a non-custodial parent who is obligated by court to pay support and send copy of my yearly tax return. I had a small business and closed it and moved last year due to family illness . I have had a professional prepare my taxes every year except for the last one I prepared myself. Child Support has NEVER inquired information to these until I did my own. Do they Legally have the right to ask me these questions and want proof?? If I don't comply, Will they most likely have me Audited by the IRS out of spite and rebuttal?
