We take seriously the responsibility to care for the tithes and donations received from members. The vast majority of these funds are used immediately to meet the needs of the growing Church including more meetinghouses, temples, education, humanitarian work and missionary efforts throughout the world. Over many years, a portion is methodically safeguarded through wise financial management and the building of a prudent reserve for the future. This is a sound doctrinal and financial principle taught by the Savior in the Parable of the Talents and lived by the Church and its members. All Church funds exist for no other reason than to support the Church’s divinely appointed mission. Claims being currently circulated are based on a narrow perspective and limited information. The Church complies with all applicable law governing our donations, investments, taxes, and reserves. We continue to welcome the opportunity to work with officials to address questions they may have.
