Under what circumstances is a 1099-C not taxable? I think I know but when a client says their attorney said it wouldn't be makes me second guess myself. If it was primary residence or taxpayer is insolvent are 2 primary ways I know of. This client was told by attorney and bank agreed not to issue a 1099-C since property(vacant lot in FL) was foreclosed. I think its taxable personally and attorney was wrong.
