What is the name of your state?Indiana. My ex has cheated on taxes for years. He overstates the amount he donates to charity. If a bag goes to goodwill, that's $1000, etc. He also claims the max amt ($500?) he can donate to church without a receipt. He is an athiest and doesn't even go. A friend of his mailed anonymous letters to the IRS this year and reported this activity. The "friend" found this behavior offensive and unpatriotic. Will the IRS audit my ex this year? Are they interested in small potatoes like this? He's a really smart guy and only cheated on things he felt he could get away with. IF he's caught, and fined (or whatever they do), will I get audited too because I was married to him for a while?
