Dues Payment Schedule

SIOP dues are $100 for professional members (Fellows, Members, Associates, International Affiliates) and $50 for Student Affiliates & Retired statuses. To transition from professional membership to retired status, please contact us at siop@siop.org or 419-353-0032.

SIOP is an individual membership organization. We do not offer corporate memberships or group discounts.

SIOP accepts dues payments all year long, but membership is based on the “SIOP dues year,” running from May 1 – April 30.  The membership renewal time is defined as May 1 – June 30.  All current members owing dues are sent membership renewal notices via e-mail in early May, when the new dues year begins.  Membership dues must be paid by June 30.  All unpaid memberships are deactivated on July 1.  Individuals with deactivated memberships will no longer receive membership benefits, such as access to the member directory, subscriptions to TIP and the IOP journal, the ability to submit conference proposals, eligibility for committee service, and more.

The following conditions apply for those making dues payments outside of the May 1 – June 30 window (for instance, new members or those rejoining SIOP after a membership has lapsed):

  • If you make a dues payment between July 1 - February 28 (or February 29, in a Leap Year), your payment will count towards the current dues year.  This means you WILL owe dues again in May when the new dues year begins.
  • If you make a dues payment between March 1 - April 30, your payment will count towards the coming dues year.  This means you will NOT owe dues again in May when the new dues year begins.

Membership benefits are activated immediately upon dues payment.  There is no prorating of membership dues for those joining during the middle of a dues year.  Print subscriptions to the IOP journal begin with the next available issue. You must opt-in to receive a print edition of IOP, which can be done through your my.SIOP member profile once your membership dues are paid.  Back issues of TIP or IOP can be viewed digitally at http://www.siop.org/tip/tip.aspx and http://www.siop.org/journal/siopjournal.aspx respectively. 

NOTE: The dues for members of the Society for Industrial and Organizational Psychology may be deductible to you as a business expense but not as a charitable contribution.  A portion of the dues, however, is not deductible as a business expense because SIOP engages in lobbying as defined by IRS regulations in accordance with IRC Sec. 6033.  For the current dues year, 10% of the dues are not a deductible business expense.  Please note that contributions to the SIOP Foundation are tax-deductible as charitable contributions
