I'd like to claim my mother-in-law on my wife's and my tax return. She lived with us 7 months in 2007. She gets about $12,000 from Social Security each year, and has absolutely no other income. She is 82 years old, but not disabled.
1st) is the social security included in gross income for the Qualifying Relative test?
2nd) do I need to charge her rent? She's living free now here and only chips in on some food?
3rd) Can she be claimed on my return as a dependent?
