Team IHRO CANNOT provide tax advice in any way whatsoever.
Donations are for the most part considered to be "personal gifts" and gifts are not taxed as income in most countries. However, to be certain we highly recommend you get professional tax advice from a competent accountant in the jurisdiction in which you reside.
We suggest filing your donations as income and pay taxes because they go to fund our roads, emergency service such as police – fire – and EMS, infrastructure and taxes help keep our cities clean and safe.
