If my parents claimed me as a dependent on their tax return, can I also claim myself on my return?

 

If someone claimed you as a dependent on their return for the tax year ending December 31, 2025:

For Line 10a:

  • If your Form IL-1040, Line 9, is greater than $2,850, you cannot claim yourself. You will put zero on Line 10a.
  • If your Form IL-1040, Line 9, is less than or equal to $2,850, you can claim yourself.  You will put "2850.00," on Line 10a.
