"Please keep in mind that to qualify for the Section 179 Deduction, the equipment listed below must be purchased and put into use between January 1 and December 31 of the tax year you are claiming.

Office Equipment
Property attached to your building that is not a structural component of the building (i.e.: a printing press, large manufacturing tools and equipment)
Partial Business Use (equipment that is purchased for business use and personal use: generally, your deduction will be based on the percentage of time you use the equipment for business purposes)."
