Ways to Give
The University of Arizona Biosphere 2 is a non-profit educational and research organization. Your generous support will be vital to our mission in addressing the grand scientific and global challenges of our earth and its living systems. Your contribution is fully tax-deductible. Donate using the "Donate Now" button below, or the "Support Biosphere 2" graphic in the sidebar of this page.
You'll be taken to The University of Arizona Foundation website to process your contribution through their highly secured Foundation website.
Contributions to the University of Arizona, Biosphere 2 could be designated to the following programs:
- Water and energy sustainability
- B2 Institute
- Support fund for K-12 educational outreach, science camps and scientific discovery
- Solar energy research and desalinization
- Global climate change
- Undergraduate and graduate research projects
We invite you to review the following ways that you can help Biosphere 2 pursue world-class research and education outreach.
Gifts of Cash
Gifts of cash are quite common and very easy to make. Checks should be made payable to "The University of Arizona Foundation," with a note in the memo section specifying your intent to support the UA Biosphere 2. You may also designate that your gift supports a specific program, or activity.
Gifts of Securities
Gifts of appreciated securities, such as stocks, bonds, or mutual funds, can provide special tax advantages. These include a charitable deduction for the full fair market value of the gift and avoidance of capital gains taxes.
Gifts of Real Estate
Gifts of homes, ranches, and other real property can provide the same tax advantages as gifts of appreciated securities. A debt-free property that has significantly increased in value may be transferred to the UA Foundation with the donor receiving a charitable deduction for the appraised value while avoiding capital gain taxes on the property's appreciation.
Memorial or Tribute Gifts
Any gift may be designated in memory or honor of a friend or loved one. The family of the deceased, or person honored, will be notified of such gifts.
Another way to support the UA Biosphere 2 is through gifts of tangible personal property. When a gift relates to the "charitable purpose" of the UA Biosphere2, the donor may be eligible for a deduction equal to the full fair market value.
Corporate Matching Gifts
You may be able to multiply the value of your gift by participating in a matching gift program provided through an employer or board membership. Your employer's personnel office can provide you with information and forms to take advantage for this unique leveraging opportunity.
Planned or Deferred Gifts
Although outright gifts provide immediate resources for current programs, deferred gifts build the Biosphere 2 for the future. Giving through estate plans or life income gifts is particularly desirable for those who would like to support the UA Biosphere 2 with a significant gift that may not be possible during their lifetime.
Bequests by Will or Living Trust
The most common form of deferred or planned gift is a charitable bequest, made as a gift in your will. A will or living trust should be prepared with an attorney.
Life Income Gifts
Numerous tax and financial benefits may be realized with a "life income gift," such as a charitable gift annuity or charitable remainder trust. The donor makes an irrevocable gift of cash, securities or property and receives income for either life or a specified term of (1 to 20) years. When the term is completed, remaining funds go to support The University of Arizona Biosphere 2.
Charitable Lead Trusts
This type of charitable trust pays Biosphere 2 a fixed amount or percentage of an asset for a term of years. Thereafter, the assets are transferred to loved ones and applicable estate, gift and generation skipping taxes on the trust assets may be significantly reduced.
Gifts of Life Insurance
You may want to consider naming the UA Arizona Foundation/UA Biosphere 2 as the beneficiary of a life insurance policy. If the Foundation is named both the sole owner and irrevocable beneficiary, the contributor is eligible to receive an immediate charitable deduction for the policy's net cash value or the net premiums paid, whichever is less. Additional premiums paid may also be tax deductible.
Retirement Plan Gifts
Designation of the UA Arizona Foundation/UA Biosphere 2 as the primary or contingent (after a spouse) beneficiary of retirement plan assets can offer significant tax benefits since retirement accounts may be exposed to both estate and income taxes.
Retained Life Estate
You may generate a current income tax deduction by giving a home or ranch to the University of Arizona Biosphere 2, while retaining the right to occupy, rent or otherwise use the property during your lifetime. The property will not be included in your taxable estate.
The UA Foundation is a "qualified charitable organization" and meets the standards and requirements of Internal Revenue Code Section 501(c)(3). Under this provision, all contributions are deductible for federal income tax purposes (subject to statutory limitations) and for federal estate and gift tax purposes.
