3 other organizations in the IRS Business Master File list the same street address. matched by us

We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

Mission and programs · 2024

Mission

The need for trees in the Valley of the Sun has never been greater. Our communities depend on them not only for health and safety infrastructure but also for critical socioeconomic benefits and environmental heat mitigation. Through the education, distribution, and planting of the right trees in the right place, Trees Matter fosters and inspires an increased, more equitable tree canopy in the Valley of The Sun. A resilient future is possible for all generations, we just have to plant it.

Activities or mission (Part I)

To foster and inspire an increased, more balanced tree canopy in the Valley of the Sun.

  • Our Shade Tree Program provides shade tree education and distribution for local utility companies, Salt River Project, SRP and Mesa Electric, in Arizona. Working with SRP, we help implement a valley wide program that teaches thousands of residents how to plant trees strategically to reduce their air conditioning use while adding trees to the landscape. Residents are provided education on tree placement, planting, maintenance and are given 5 gallon trees to take home and plant. This year with SRP we distributed approximately five thousand trees and educated over two thousand residents. We launched the City of Mesa Electric program in Spring 2024 and are continuing to grow that program with hundreds of trees given out to utility customers in the last year.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

The four totals the IRS asks for on Part I of the Form 990, as filed. A dash means the figure was not present on the return — not that it was zero.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.

What this page reflects

The registration facts above come from the IRS Business Master File published 13 October 2026 and read 1 November 2026, for every organization at once. Returns through tax year 2024, the newest we have parsed for this organization.
