Will I receive a receipt for my donation?  

Wikimedia CH is a non-profit association recognised by the tax authorities. Therefore, donations can be deducted from taxes throughout Switzerland. For cost reasons and in compliance with tax regulations, Wikimedia CH automatically issues donation receipts at the beginning of the following year for donations over CHF 200 (total donation amount per year). You can of course request a receipt for donations below this amount, but you can also simply print out the deposit slip and enclose it with your tax return.

Why do you need my address?

We are required to ask for your address in connection with the following payment methods: credit card and payment slip. In addition, we need your address to send your donation receipts for your tax return (for a total annual donation of CHF 200 or more).

How can I hide the donation banners?  

The banner can be closed at any time by clicking on the cross in the upper right corner. The banner is then deactivated for a period of two weeks.

What is the difference between Wikipedia and Wikimedia? 

Wikimedia is the non-profit movement behind the project Wikipedia and runs this project, supports the work of volunteer authors and photographers and simplifies this work through technical development. Wikimedia is an international movement, with the US Wikimedia Foundation (WMF) at its centre. WMF is the operator of Wikipedia and, for example, carries out the international fundraising campaigns. There are also about 40 country representatives of Wikimedia who promote free knowledge locally. Wikipedia is the international project; Wikimedia is the collective term for the organisations behind Wikipedia and its sister projects.

Is anonymous donation possible? 

Yes, it is. If you want to make an anonymous donation, you must do it via our partner, the online philanthropy portal StiftungSchweiz, who will transfer your amount to Wikimedia CH but not your personal data. Fill in Wikimedia CH's donation form at StiftungSchweiz's website and tick the box "Ich möchte anonym spenden". This page currently exists only in German. Please note that we will not be able to issue a tax receipt for anonymous donations.

Why is Wikipedia financed by donations and not by advertising? 

Access to free and unbiased knowledge is more important than ever in today's world of fake news and misleading information. Wikipedia, Switzerland's 5th most visited website, represents a collective resource that belongs to all of us. Donations help us to stay independent, to maintain and further develop the online encyclopedia and our different Wiki projects to promote free knowledge.

How can I order multiple payment slips? 

To order multiple payment slips please write an e-mail to We will send them to you. Maybe you should consider to set up recurrent payments with your bank. Therefore please contact your bank.

How can I donate regularly? 

There are several ways to make regular donations: Either you click on "I would like to donate regularly" in the online donation form and select your preferred donation interval, or set up a standing order with your bank. The latter is the simpler option for us. The regular donation can be adjusted or terminated at any time.

Where does my money go? 

Wikimedia CH carries out a variety of programs in collaboration with institutions and other partners. On one hand, we offer basic training in the use, creation and editing of content for Wikipedia and other Wiki-Platforms. On the other, we organize projects and workshops on the topics of life-long learning, working with net-based information, teaching of digital skills as well as online collaboration. Your donation helps us to continue our engagement. Donations which are generated by banner campaigns on Wikipedia go directely to the global wikimedia movement. All other donations will support Wikimedia CH projects.

Can I mention Wikimedia CH in my will? 

Yes, you can. Remembering Wikimedia CH in your will is easy to do. In this way, your support for the values of free knowledge will live on after you. Your generosity will help to guarantee that the association Wikimedia CH remains effective and independent.
