Relating to the election dates for certain special and runoff elections.

HB 4005 amends Texas election law to establish specific timing for special and runoff elections. It requires runoff elections for special elections (filling congressional or legislative vacancies) to occur between the 30th and 70th day after the main election canvass, instead of the previous 77th day limit. The bill also sets runoff primary elections for the fourth Tuesday in May and mandates special elections to be held within 90 days of a vacancy, unless the vacancy occurs close to a regular election cycle. These changes apply only to elections ordered on or after September 1, 2025.
