A whistleblower complaint filed at the Internal Revenue Service in November by a knowledgeable church member alleges that a non-profit supporting organization controlled by the Church of Jesus Christ of Latter-day Saints used member tithes to amass more than $100 billion in a set of investment funds and the Church misled members about uses of the money.

The complaint may be the most important look at LDS finances in decades, a window into one of the wealthiest religious organizations in the United States and the world. Details of the IRS filing reveal financial assets largely hidden from the church's membership (often known as "Mormons") and the public view. 

The 74-page document filed with the IRS and obtained by Religion Unplugged shows that Ensign Peak Advisors, Inc. (EPA) owned assets under management grew to more than $100 billion from $10 billion in the past 22 years, fueled by a mix of investment strategy and tithe money from church members. 

Religion Unplugged reached EPA's managing director Roger Clark by phone on Monday, offering to explain key parts of this story and to ask questions for EPA to give a response. "We don't really answer questions with the public press. So thanks," he said, before hanging up the phone.  

Ensign Peak Advisors' articles of incorporation confirm Ensign Peak is an arm of the Church of Jesus Christ of Latter-day Saints. As registered under section 509(a)3 of the Internal Revenue Code, Ensign Peak Advisors, Inc.  EPA is a "supporting organization" of the Church under article 3 in its registration document. Upon dissolution, all Ensign Peak assets go the Church or affiliated organizations according to article 5 and that article cannot be changed without "the written consent of The First Presidency" of the Church. Because Ensign Peak Advisers is a support organization to a church it is not subject to disclosure requirements that other non-profit organizations are required to make.
