Upon looking back at it, I clearly misread you—there’s a pretty big difference between donating 30-33% and keeping 30-33%. Apologies.
(Also, while I suspect you’ve probably considered this, is that the most tax-efficient way of donating? I can’t speak to American tax law, but up here in Canada, one person donating all their income is a waste of possible tax credits, and the goal should be to bring both partners down to a similar post-donations income to minimize tax payable)
Julia and I file as “married filing jointly” which means from the government’s perspective we’re one financial unit that earned some money and donated some money. With my 30% (pre tax) and Julia’s 100% (post tax), last year came to 40.5% overall (pre tax).
Talking about having separate numbers for the two of us does tend to confuse people, though, so we’ve switched to both of using giving 50% (pre tax).
