Tobacco premium is pre-tax 

If you are enrolled in a Texas Employees Group Benefits Program health plan and use tobacco or have covered family members who use tobacco, you must certify you and/or your family members as tobacco users and pay a higher premium. The tobacco user premium is taken out of your paycheck pre-tax. You pay $30, $60, or $90 more each month in additional health insurance premiums, depending on how many tobacco users you cover. 

Tobacco users  Monthly fee 
Member only $30
Spouse only $30
Child* only $30
Member + spouse $60
Member + child* $60
Spouse + child* $60
Member + spouse + child* (Family) $90
*The charge for a child is the same regardless of how many children in the household use tobacco. 

Certify tobacco use by signing in to your account, calling ERS toll-free at (866) 399-6908, or by contacting your benefits coordinator or accessHR.
