Register With the Harris County Voter Registrar Before the Deadline
The Harris County Tax Assessor-Collector does more than cars and property taxes. That office is also the county's Voter Registrar. To vote in an election, your registration has to be on file at least 30 days before Election Day. A signup during election week counts for the next one, not the current ballot.
Moving is the easy thing to miss. If you change your name or move to a new Harris County address, send in a completed and signed application to update the record. Otherwise, the roll may still point to the old house.
Forms come in English, Spanish, Vietnamese, and Chinese. The Tax Office voter page lets you check whether the record is current before election season sneaks up.
