Can i claim my father even though he gets social security

Perhaps.  A dependent must meet the requirements of a qualifying child or a qualifying relative in order for you to claim them on your tax return.  

The tests for a qualifying relative are: 

Qualifying Child: They are not the “qualifying child” of another taxpayer or your “qualifying child.” 

Gross Income: The dependent being claimed earns less than $4,700 in 2023. (Generally, you do not count Social Security income, but there are exceptions. If your parent has other income from interest or dividends, a portion of the Social Security may also be taxable.)

Total Support: You provide more than half of the total support for the year. 

Member of Household or Relationship: The person (a friend, girlfriend, non-blood relative) must live with you all year as a member of your household or be related to you. 

TurboTax software will ask you simple questions and give you the tax deductions and credits for which you are eligible based upon your answers.
