Dues Waiver Request

Any SOT member in good standing whose employment is temporarily interrupted may apply for a waiver of dues for a period of up to one year. A dues waiver may be renewed for an additional year upon reapplication. Eligible members desiring a waiver of dues must submit a written request to the SOT Executive Director, which includes a description of the most recent employment history. Requests for dues waivers will be maintained confidentially and will be individually reviewed by the Membership Committee for recommendation to Council. Members granted dues waivers will continue to receive the SOT newsletter, journal, and will be permitted to submit abstracts and register for the Annual Meeting at the member rate.

Membership Dues Assistance Program

SOT encourages international membership and recognizes that toxicologists are active in areas of the world where even reduced SOT dues payments may present a technical challenge (e.g., mechanisms for fund transfers to the US may be costly or not available) or financial concern. SOT Council maintains funds for a Membership Dues Assistance Program for Student and Postdoctoral Members from countries on the SOT Developing Countries list. Applicants who request membership dues assistance on the SOT membership application form will receive a follow-up request for a letter explaining why it is difficult for them to pay SOT dues.
