Hacker School gGmbH is a registered nonprofit in Germany. Donations to recognized charitable organizations (gemeinnuetzige Organisationen) are tax-deductible up to 20% of your total income. You will need a donation receipt (Zuwendungsbestaetigung) from the organization for your tax return.

You can verify Hacker School gGmbH's charitable status in several ways. First, check the Zuwendungsempfaengerregister (ZER) at https://www.bzst.de/DE/Unternehmen/Zuwendungsempfaengerregister_organisation/zuwendungsempfaengerregister_organisation_node.html - the BZSt maintains this federal register of all organisations eligible to receive tax-deductible donations in Germany. Second, you can look up the association in the Vereinsregister (association register) at the local Amtsgericht (district court) via https://www.handelsregister.de/ - this confirms the legal form, registered address, and board members. Third, check whether the organisation holds the Freistellungsbescheid (tax-exemption notice) from its local Finanzamt - the notice is re-issued every three years and confirms the 'gemeinnuetzig' status under the Abgabenordnung. Legitimate charities publish this on their website or provide it on request.

You can donate to Hacker School gGmbH directly through its donation page (https://www.globalgiving.org/projects/inspire-children-for-it-and-programming/). German charities typically accept SEPA bank transfer (Ueberweisung) to the organisation's IBAN, SEPA direct debit (Lastschrift/Einzugsermaechtigung) for recurring donations, PayPal, credit card payments, and online payment processors like Stripe or Mollie. Many German charities use platforms like betterplace.org, GoFundMe, or their own Spendenseite (donation page). International donors can give via SEPA transfer (Germany is in the eurozone) or PayPal. For your donation to be tax-deductible, you need a Zuwendungsbestaetigung (donation receipt) from the organisation - for amounts up to 300 euros, a bank statement showing the transfer is sufficient.
