For participants either living in the Netherlands or outside of the Netherlands applies that if they recieve more than 50 euros from Leiden University, with a maximum of 180 euros per month (this can be from different researches), then we must announce this to the tax authorities. You should inform the research participant of this in advance.. Leiden University does not send out additional notices.

Payment to research participants outside Europe

You can make payments to research participants from NON-SEPA countries (outside Europe) by bank transfer or in the form of a gift.

Extra transaction costs are always charged to the university for payments to NON-SEPA countries. This starts at 4.50 euros per payment and can be higher.
