An individual may claim a nonrefundable tax credit for making contributions or paying fees directly to a public school in this state. The School Tax Credit Donation Portal consists of a color coded map of every school district in Maricopa County.Nonprofit fundraising letter template. Nonprofit organizations use it to support school-related initiatives. 4. Local businesses may want this template to offer support to educational institutions. 5. Note: A school tuition organization cannot award, restrict, or reserve scholarships solely on the basis of a donor's recommendation. You will be asked to designate a specific time to donate. Once that time has passed, you will receive an email noting that the recurring donation is passing. What this means is you can donate to a certified school tuition organization such as Arizona Christian School Tuition Organization. All prospective Maricopa Community Colleges students under the age of 18 must complete this process prior to enrolling in courses.
