It can be depreciated over its "useful life".  Unfortunately, there is no clear-cut answer to what that is.  And even if there was a clear-cut answer, I don't think TurboTax is capable of correctly doing that type of depreciation (that type of depreciation also requires using a "salvage value" and I don't think the program is capable of doing that).

Equipment is 7 year property or 10yr SL. 

Thanks. I was going to use the "safe harbor" 3-yr, but its for a multi-member LLC. I will use seven years.
