Dear Colleague,
If you are renewing a membership, please select the desired membership type below and then review and update your profile. If you see no choices below, your membership is current.
Yearly membership dues are €70 for full members and €35 for students* and members who are retired.
- Your Membership Account page summarizes your payment and membership history. Please pay below for the next year. If you see no choices below, your membership is current.
- Recurring memberships (yearly subscriptions) will be offered between 15 December and 31 January.
- If you have an expired membership and wish to pay for years missed, please send an email to support.
- *If you are contemplating taking the student/retired discount, please review the criteria in advance of doing so. If you renew as a student or retired, you will be contacted by the Executive Officer to request supporting documentation.
- When you make your selection below, you will be able to update your profile information and then complete the checkout process.
- You will be brought to the Stripe payment portal. You will be offered payment options based on those services available in your country. If you are offered Bank Transfer, please select Euros as the currency.
- Please note: paying by bank transfer is costly for non-EU countries because of high transaction fees. We request that you pay with credit card. Or, if you pay by bank transfer, please pay the fee(s).
- You will be brought to the Membership Confirmation page after payment where you can review your Order information.
- Then please review your profile information and make any necessary updates.
- If another person or organization is making payment for your membership, please indicate that name in the Payer field as it will appear on the credit card payment or on the bank account payment.
- Please use the Roman alphabet.
- Some members have had questions about the processing of renewals. Learn some answers here.
Conversion to your currency (if necessary) will be calculated by Stripe. For example, on 11-December 2025, the €70 membership was $81.90 US dollars.
Thank you for supporting the ISTFP.
