If you are independent for tax purposes, you may gain resident status if you establish domicile in the state. If your parent(s) claim you as a dependent on their federal income tax return, they must establish domicile in the state for you to claim residency.
To establish domicile, you or your parent(s) must meet the following criteria:
1. Live in Texas for 12 consecutive months; and
2. Establish and maintain domicile for 12 consecutive months by doing one of the following:
- Be gainfully employed in Texas (Student jobs do not qualify as gainful employment.)
- Sole or joint marital ownership of residential real property in Texas by the person seeking to enroll or the dependent's parent, having established and maintained a domicile at the residence
- Own and operate a business in Texas
- Be married for one year to a person who has established domicile in Texas
