I am to the point of entering my charitable contributions and got tot he "How often you give" question. Just for kicks I decided to enter the same info all 3 ways (One time, Multiple times same amount and Multiple times different amounts). If I use the One time option, a contribution of $4800 drops my tax liability by $6166. If I do multiple times / same amount the tax liability doesn't change. If I do multiple times / different amounts the tax liability drops by $6166 again. Why is there a difference due to how the money was contributed?
