The end of the year is approaching. I believe that in the United States, if the letter is postmarked by December 31st, a charitable donation counts as deductible for that tax year. If you’re not aware of them, GuideStar and Charity Navigator are two good places to start.
I think I know what I’m doing charity-wise this year, but readers might enjoy seeing what other people suggest. Does anyone want to mention specific charities? Or mention other things that might not strictly be charities, but might be “good deeds” that readers would be interested in?
