>A simple one that comes up a lot is back dating when a donation "occurred" to be within a certain tax year. Donations don't "occur" until they are processed completely. The end of the tax year has lots of donations come in. If the foundation isn't on their toes, they might not process all of them in time for the tax deadline To fix this, many nonprofits have a fiscal year that is different than the calendar year (calendar year being Jan - Dec) while a fiscal year can be any 12 month period (for example, July beginning to June end). The organization reports based on its fiscal year, so it has plenty of time to process December donations.

(this details for nonprofit orgs but the same can be done for businesses and sole-proprietor orgs should this interest someone).
