SETI@home is a nonprofit educational and research organization that relies significantly on donations to continue operations. E-mails are currently being sent to all our users asking for their help. This process takes time (we expect to be finished by Nov 23rd). Perhaps your spam filters blocked our e-mail. If you haven't gotten your e-mail yet, you can always read it on line.

And don't forget to tell a friend about SETI@home - we can always use more computing power!

Q: How private is your mailing list?
A: SETI@home does not share its mailing list with any other organization.

Q: Is my donation tax deductible?
A: If you are in the United States and Canada, your donation is tax-deductible. The University of California is a nonprofit educational and research organization governed by the provisions of Section 501(c) (3) of the Internal Revenue Code. The University's Federal Identification number for reporting and tax purposes is 94-6002123.

Q: What if I'm not in the U.S.?
A: The conditions for tax deductibility described above may only be applied to taxes paid within the United States of America. For any other country or territory, the local legislation and/or International Conventions may sometimes allow you to benefit from similar local deductions, which would apply for the reasons of supporting educational projects and scientific research. You must verify these conditions yourself.

Other ways you can donate:

• If you would like to set up a monthly/quarterly donation directly from your checking/savings account, please fill out this form and send it to the address at the bottom (make sure to put "SETI@home" as the fund name). Warning: since this method is not automated you may not get a green star after your donation is completed.

• If you want to donate by check/money order, please follow the instructions on this form.

• PayPal users: We vastly prefer the other donation methods listed above (due to lower overhead and ease of management), but if you can't contribute to us otherwise, you can now use PayPal. Thanks to the helpful support of the GPU Users Group, they are collecting donations via PayPal for SETI@home, which (after the standard PayPal overhead) is redirected entirely to us for general use or to then purchase specific pieces of hardware. The GPU Users Group is a 501(c)(3) charitable organization, so donations made via this method are similarly tax-deductible. If you use this method, there may be a long delay (as much as a month) before you obtain your green star. For more information, or to make a donation through the GPU Users Group, click here.
