If I’m not filling myself and the person I’m living with want me to claim me, will that be okay?

So you had to live with them the whole year and make less than 4,050 total income for the year for them to claim you.  I didn’t see the 4,050 income limit mentioned.

• They aren’t filing a joint return with their spouse.
• They are younger than you and under the age of 19 (or 24 for full-time students).
• No age limit for permanently and totally disabled children.
• They live with you for more than half the year (exceptions apply).
• They did not provide more than half of their own support.
