I found this at
Members of The Church of Jesus Christ of Latter-day Saints expect Zion to be established in Missouri, which will be called New Jerusalem during the Millennium. The United Order will be practiced in Zion and will be the economy of Christ everywhere on earth during the Millennium.
“Under this plan, the head of each family would consecrate or deed all real and personal property to the Presiding Bishop of the Church and would receive, in turn, a stewardship, or “inheritance,” from consecrated property. Thereafter, Church members would consecrate annually all surplus production from their stewardships to the bishop’s storehouse.”
Well, I guess that solves the tithing problem. If you don’t own anything, then it’s pretty easy to give 10% of nothing, isn’t it?
Tractor Boy can fill us in on some details about this.
