You MUST contact us to confirm the number of remaining NAP credits available to you and your eligibility prior to making your donation. We will not refund donations made prior to confirming NAP credit eligibility and availability. If you’d like to submit your donation (checks preferred, but online donations accepted) with the required paperwork, we’ve included the required form below. The first page goes to Tandem, the second and third pages are informational for you (the 3rd is an EXAMPLE of what it will look like when you file your taxes).
