But I'm also pretty sure a non-profit can write off processing fees so it's not really an issue.
How would the employee get tax write off if the money is send to your company which is not registered as 501(c)?
For example if you claim a deduction on your taxes and get audited, would IRS be cool with 'I send money to XYZ which is not a 501(c) but they send it to actual charity, I swear'.
Offering receipt of donation to every company employee would work (I think), but I'm not sure if you are doing that?
