I am recently divorced and have been staying with a friend since Dec. 6, 2012. I did not work until April and now it is only part time. I am soon to receive a $7500.00 payment from my ex-husband. My friend has not charged me for rent or bills, but I do give her money for food and also buy most of my own food. She informed me today she and her husband are claiming me as a dependent next tax season. What does that mean for me? I make less than $1000.00 a month but with the $7500.00 I am now afraid I will owe the IRS more than I can afford. I live in California.
