Julia is 46 and made $32,000 in wages in 2016. She is single and pays all the cost of keeping up her home.

Julias daughter, Beth, lived with Julia all year.

Beth is 27, single, and had no income in 2016. She is not disabled. Beths baby, Piper, was born in November 2015. Piper lived in Julias home since birth.

Julia provides more than half of the support for both Beth and Piper.

Julia, Beth, and Piper are all U.S. citizens with valid Social Security numbers.

All I want to know is that who can claim Piper as a dependent and why? Also, who can Julia claim as a qualifying child(ren) for the earned income credit?

Thank you
