I wanted to do this, but 7.5% is taken out before the money gets to the charity. That is more than credit card processing fees! I no longer use that option and donate directly. Doing that does increase the amount of work to do your taxes if you itemize deductions though.

This is not going to gusto, but it taken out as part of the services provided by FirstGiving their partner to handle the donations: https://support.gusto.com/hc/en-us/articles/220929687-Charit....

Oh, I had no idea. In that case no I wouldn't use that, I'd set up a recurring donation directly. (I recently changed payroll processing and haven't transferred the donations yet).
