Can I owe additional taxes if I never sent in form 4502 (franchise tax board) ? What does that mean?

I filed taxes in California. It’s my first year doing taxes. What happens if I never sent form 4502 in and what will happen?

If you do not send the required supporting documentation within 30 days of the notice date, they will deny all or some of your Cal EITC.  This could result in you owing additional taxes.

The CA EIC requirements are stricter than those of the IRS.

However, if you believe you qualify, send the info in now.
