General
Wikimedia CH has been recognised as a charity by all cantonal tax offices in Switzerland. Your donations are thus tax-deductible all over Switzerland.
Important: to save on costs, and in accordance with tax regulations, at the beginning of the following year, Wikimedia CH will automatically issue donation receipts for donations above CHF 200.- (total annual donation amount).
For donations below this amount, you could, of course, ask for a donation receipt or simply print out your proof of payment and attach it to your tax declaration.
Thank you very much for your understanding!
