A charitable remainder unitrust is an irrevocable trust created under the authority of Internal Revenue Code ยง 664[1] ("Code"). This special, irrevocable trust (known as a "CRUT") has two primary characteristics: (1) Once established, the CRUT distributes a fixed percentage of the value of its assets (on an annual or more frequent basis) to a non-charitable beneficiary (which is considered the settlor of the trust); and (2) At the expiration of a specified time (usually the death of the settlor), the remaining balance of the CRUTs assets are distributed to charity. The trustee determines the fair market value of the CRUT's assets at the time of contribution, and thereafter on the applicable valuation date. The fixed annuity percentage must be at least 5% and no more than 50% of the fair market value of the assets in the corpus. The remainder (the amount expected to go to charity) must be at least 10% of the fair market value of the assets contributed to the CRUT. Code Section 664(d)(1) sets the federal income tax requirements for a charitable remainder unitrust. Example Assume an individual, Mr. Smith, has $1 million of publicly traded stock and would like to establish a CRUT. Assume the CRUT is set up to pay the annuity to Mr. Smith over his lifetime. Mr. Smith selects a 10% CRUT. The CRUT will pay Mr. Smith 10% of its assets (initially $100,000) per year until Mr. Smith dies. At that time, any balance remaining in the CRUT will be distributed to charity. The term "unitrust" means the annuity percentage is fixed; the CRUT will distribute 10% of the value of the CRUT's assets each year, the CRUT's value may increase or decrease over time.
