<prompt> Human: In the sense of having a tax cut if so what are the limits on how much you save? How much is the minimum before you save?  <response>: You dont save more than you donate, no. But if you were going to donate anyway its nice to get the tax break.You can also donate appreciated securities without having to pay the capital gains. So if you invest 5k, it doubles in value to 10k, and you donate the whole 10k you can take a 10k deduction on your taxes saving you 3500 if your marginal tax rate is 35 plus you avoided paying capital gains on the 5k appreciation saving you 750 if your capital gains rate is 15.So you donate 10k which originally cost you 5k but you save 4250 in taxes. The charity, being tax-exempt, can then sell the shares without paying taxes on the gains. Youre still out money of course - no one is making money by donating to charity.There are caps and rules, everything isnt always so simple.You can read more here:
