Event registration fees can be treated as donations or as fees (non donations).
To see or change whether your registration fee is a donation or not, go to your Event Dashboard and click 'Settings' > 'Registration settings' in the left hand menu.
Scroll to the bottom of the screen to see the Beneficiary payment options. Here you can see the Registration fee type and who the registration fee goes to.
If the registration fee type is set as donations, the registration fee will show as a donation on the participant's fundraising page, and the funds will be paid to the charity listed on the fundraising page.
If the registration fee type is set as non-donation, the registration fee will not show on the participant's fundraising page, will not be tax deductible for the registrant, and will be paid to the event owner (the organisation that has created the event).
If registration fees are non-donations, and not appearing on participant's fundraising pages, but you would still like them to appear in the total amount raised for the event, go to the event website editor, click on the total amount raised block (the thermometer) to open its settings panel on the left, and scroll down to the 'Data' section, where you will see checkboxes for which types of funds are included in the total.
