Qualified Charitable Distributions

Annual withdrawals from traditional retirement accounts are required after age 70-1/2, and the penalty for skipping a required minimum distribution (RMD) is 50% of the amount that should have been withdrawn. However, if you are in the fortunate position of not needing your distribution for living expenses, you can avoid income tax on your required withdrawal by donating directly to a qualifying charity such as Boyce Thompson Arboretum.

Matching Gifts

Are you interested in doubling, perhaps even tripling your gift to BTA? Many companies will match their employees’ gifts, often up to $3,000 per year, at no additional cost for employees, and the Arboretum can benefit! Please check with your HR department to find out whether your company is a matching gift sponsor.

Arranging for a matching gift is as easy as 1-2-3:

1. Get a copy of your matching gift form from your company’s HR department and mail or drop it off with your gift.

2. BTA will verify your gift and return the matching gift form directly to your company’s designated matching partner.

3. Boyce Thompson Arboretum will then receive a check from your employer, matching your gift. You will receive recognition credit.

Already gave? Most matching companies will honor gifts given within the current calendar year. Simply send or bring your matching gift form to the Development Office, and we’ll take it from there! For more information, please call (520) 689-4588 or [email protected].
Thank you for considering this simple and effective way to support Boyce Thompson Arboretum!

Gifts in Kind

Gifts of tangible personal property (books, artwork, plant specimens, etc.) can be accepted if they further the mission of BTA. The Gift Acceptance Committee may, at their discretion, choose to accept a gift of tangible personal property that is readily marketable for the purpose of liquidating the asset. Property for the use of BTA with an appraised or estimated fair market value of less than $500 may be accepted by the receiving department in consultation with a Development Officer. Gifts of property valued at $500 or more must be approved by the Gift Acceptance Committee.

Wills and Planned Gifts

“Someone is sitting in the shade today because someone planted a tree long ago.”
— Warren Buffett

Planned giving enables you to extend your legacy into the future. It helps strengthen the Arboretum and can address your estate-planning needs through tax advantages and other benefits; in some cases, it may increase your retirement income.

When estate gifts are added to our endowment fund, they enhance the Arboretum’s long-term financial stability by providing a continuous revenue source for ongoing operational expenses, designated projects and special needs.

Working together, we will always seek to devise a plan that serves your philanthropic goals and financial objectives, as well as the Arboretum’s. Examples include:

Estate gifts: Bequests from wills, living trusts, or retirement plan assets. Here is some sample bequest language you may want to share with your attorney:

“I give and devise to Boyce Thompson Arboretum, located in Superior, Arizona, all (or state a percentage or a dollar amount) of the rest, residue and remainder of my estate, both real and personal, to be used for its general support.”

Income-producing gifts: Charitable gift annuities, charitable remainder annuity trusts and charitable remainder trusts are simple arrangements that pay a donor or loved one income for life in return for a donation to BTA. We’ll work with caring, certified financial advisors to carefully steward these gifts, and after the beneficiary’s lifetime, the remainder will help advance our mission.

Life insurance: You can name the Arboretum as a beneficiary of part or all of your life insurance policy. If you contribute future premium payments, BTA will record and acknowledge the amount of the premium payment as a gift in the year that it is made.

Other planned gifts: Charitable lead trusts, gifts of real estate, or other unique assets.

Donors of planned gifts are recognized as members of the Desert Willow Legacy Society and are invited to attend special donor events. Click here to download our Desert Willow Legacy Society form to learn more!

Have you included Boyce Thompson Arboretum in your will or other estate plans? Let us know! We want to stay in touch and ensure that we can report the impact of your generosity. If you would like to discuss your estate planning goals, please call Allison Lester at (520) 689-4588 or email [email protected]

Gifts of Stock

Publicly traded marketable securities may be transferred to an account maintained at our brokerage firm or delivered physically with the transferor’s signature or stock power attached. As a general rule, all marketable securities shall be sold upon receipt unless otherwise directed by the investment committee. In some cases, marketable securities may be restricted by applicable securities laws. For more information, please call (520) 689-4588.

Major Gifts

Major gifts are critical for realizing the Arboretum’s bright future, whether they finance construction of a pavilion or patio, support educational programs that teach future generations about the importance of the natural world, or fund the upkeep of spectacular gardens. Major donors who contribute to the Arboretum have an incredible impact. The buildings, gardens and programs they fund will be a testament to that fact for many years to come.

Donors may be offered a selection of naming opportunities based on the amount and date of their gift commitment. The duration of the naming agreement will be determined at the time of the gift. To discuss opportunities for major giving, please call Allison Lester at (520) 689-4588.

Tiny cuttings, big impact.

Every plant you see here started from just a snip — carefully cleaned, dipped, and rooted with care. Propagation isn’t just practical. It’s powerful. It helps us grow more plants for pollinators, restoration, and education — all while conserving precious resources.

But we can’t do it alone. Your support helps us expand our propagation efforts and grow the future of this garden.
