No, IA is a US non-profit, that status does not apply for EU non-profit donations as tax deductible.
There also isnt really an european branch of the IA to donate to, to support the infra/core mission. The other IA Locations(Canada, EU, Swiss) are mostly idependent(probably to avoid any issues with the others, if one does have governance/legal issues), however they share the same mission in aquiring data to save and working with libraries.
Send EUR via SEPA transfer to GB74RBOS16107510000470. (Yes, the page only mentions wire transfer, but SEPA transfers work too, are faster, and cost everyone less.)
there would still be fees for a wire transfer from a EU bank to this bank in the US, right? And I wouldn't get a donation receipt that would be accepted by the tax man over here anyway.
