Hi all, I got a letter from the IRS about being extra cautious on EIC.. so I have a client she worked for uber only made $1,500 she wants to file taxes and claim her daughter. I asked if she had other income and she stated no. I asked who paid for the rent utilities etc cost of living and she said her dad so i told her based on that the grandpa (her dad and child's grandpa) needs to claim her his income is over 80k and she declined and told me no. I told her i don't believe she is eligible to claim EIC or CTC for her daughter and told her i will get back with her. Can you guys please confirm if i am correct? She is not eligible since she did not support her daughter and lives with her dad. Some facts she is 25 not a student and receives child support to buy food and clothes. but grandpa pays mortgage utilities etc.
