How do I know if I truly qualify for the early childhood tax credit if I am a teacher and it is allowing me to select it?

You are responsible to make sure you meet the qualifications. In order to qualify for this credit, you must have:

• Held an Early Childhood Professional Credential issued by the Colorado Department of Early Childhood for at least part of the income tax year, and 
• Been either the licensee of an eligible program or employed by an eligible program for at least six months of the income tax year.
