Charitable Planning: Effective Year-End Giving

Whether due to a sudden attack of generosity, last-minute tax planning, or just procrastination, many charitable gifts are made just before the donor’s year end. Year-end donations of intangibles, tangibles, or real estate (or similar properties) each have their own year-end challenges.
