I've read that publication, and it is beyond confusing as to what is allowable and to what degree.
Logically, it makes sense to me that i should be able to have some degree of deduction for having a third of my detached garage dedicated to the storage of work tools and materials that are necessary for me to earn an income in my field. Not everything could possibly fit in my truck, and storing things outside would eventually destroy them. Thus, a secure storage facility is an essential component of my business and one that carries its own expense.
The IRS publication seems to agree with me:
"You can deduct expenses for a separate free-standing
structure, such as a studio, workshop, garage, or barn, if
you use it exclusively and regularly for your business. The
structure does not have to be your principal place of busi-
ness or a place where you meet patients, clients, or cus-
tomers.
But there does not seem to be any clear way to do this deduction on turbotax.
