Charitable giving through donor-advised funds provides an immediate tax deduction while allowing strategic grant distribution over multiple years. Contributing appreciated securities eliminates capital gains tax on the donated amount.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.
