Print Lifeline application

Lifeline and LinkUp America are designed to provide low-cost telephone service and free installation to certain low-income residents living on former tribal land. LinkUp America helps first-time qualified customers connect on a one-time basis to the national telephone network at no charge, allowing SST to waive the normal $28 installation fee.

The Lifeline credit applies to basic service only and reduces the monthly cost to about $1 plus required regulatory fees and taxes.  There is no discount for extra features such as call waiting. New enrollees must provide proof of eligibility.

Check Sales Tax Relief Guidelines

If your household meets the guidelines, then you qualify to file Form 538-S.  Once Form 538-S is approved, you then qualify for discounted telephone service through Lifeline.  Oklahoma residents qualify with household income of $20,000 or less if single, or, if married with no dependents. Expanded guidelines now include residents in households earning $50,000 or less with a dependent, or, if you or your spouse are 65 or older, or, if you have proof of a physical disability. You may file your claim for a sales tax refund even if you aren’t required to file Oklahoma income tax.
