My employer changed their donation matching policy such that I now have an incentive to lump 2 years' donations into a single year, so I can claim the standard deduction during the year that I don't donate, thereby saving around $1200 every 2 years. I've been donating between 10 and 12.5 percent for the last few years. This year I would be donating around 21%. Has anyone here been audited because they claimed a large fraction of their income as charitable contributions? How painful was the experience? I doubt it's worth paying $1200 to avoid, but I thought I'd ask.
