Every month a portion of your monthly plan payments are contributing to a Native American Tribal Entity for the purpose of enhancing the lives of tribal members be that for education, healthcare or other worthy causes. A Tribal Entity works like a 501 (c)(3). You do not need to be a Native American to join and receive benefits.
Members on an individual plan receive a Donation Receipt for their monthly payments and enrollment fee at the end of the year, plus an ACA Exemption letter. Just another extra Bonus. Please consult your tax professional for advice on all taxation matters.
