You posted in a topic from June 2015. You know there are new Tax Laws voted in Dec 2017.
Please note that Printer Paper, Plants, etc are Not Fixed Assets; these are regular Office Expense. Think of the difference as between Expense = all used up quickly (printer paper, toner cartridge, electricity) vs Expenditure (desks and new walls and flooring and vehicles) = having a useful life of more than one year, lasts a long time but wears out over that time a bit = Depreciation. Section 179 is part of Accelerated Depreciation.
And what you asked might not even apply at all, now that this is no longer 2015 (the year of this topic) but 2018.
For instance, everything you used to know about Depreciation is changing. This is from an IRS e-newsletter just last week:
"The 100-percent depreciation deduction generally applies to depreciable business assets with a recovery period of 20 years or less and certain other property. Machinery, equipment, computers, appliances and furniture generally qualify.
The deduction is retroactive, applying to qualifying property acquired and placed in service after Sept. 27, 2017. The proposed regulations provide guidance on what property qualifies for the deduction and rules for qualified film, television, live theatrical productions and certain plants."
What that means is that Section 179 might be Superseded and will be removed from the tax code. And pay attention to the word "retroactive" = applied to the end of Last Year.
