There's this saying that tax deductions are a primary motivator for a donor's charitable gift. Personally I think the role the tax deduction plays is overstated, particularly when talking about giving things like clothes and cars.
But whatever its role, donors do need to be conscious of exactly how they make tax claims about their donations. Stepping-in to be helpful on this and a number of charitable-related matters is the Wall Street Journal in this article.
I found two items particularly noteworthy. One item, basically focused on "judging a book by its cover" reminds prospective donors to not singularly rely on the charity graders (like Guidestar or Charity Navigator) as their only source of information (positively or negatively) and with that, not to singularly judge a nonprofit based on the pay its exec receives. There's more to a nonprofit than these two items.
The other, a question I find frequently asked by nonprofit boards, is whether they, the organization, should be carrying Directors & Officers insurance. Check-out the answer.
