Bristol Palin was 18 when she was appointed as a teen ambassador for the New York-based foundation in 2009, months after giving birth to son, Tripp. She and the 2-year-old boy's father are no longer together.
Palin family attorney John Tiemessen and foundation officials did not immediately return calls for comment.
Palin is still listed as an ambassador on the foundation's website. The blog Palingates first reported the compensation figure.
