Can I claime 2 of my married parents as dependent if they are retired and living in my house and getting only Social Sequrity income

[MinhT · Accepted solution]

Yes, you can claim them as dependents if you provided more than half of their support in 2018 and they earned less $4,150 (Social security benefits do not count as income).. 

They can not file a joint return unless that return is only filed to get a full refund of tax withheld.
