here is abstract from IRS publication 946 - depreciation
and 168(k)(7)
How Can You Elect Not To
Claim an Allowance?
You can elect, for any class of property, not to deduct any
special depreciation allowances for all property in such
class placed in service during the tax year.
To make an election, attach a statement to your return
indicating what election you are making and the class of
property for which you are making the election.
The election must be made separately by each person
owning qualified property (for example, by the partnerships, by the S corporation, or for each member of a consolidated group by the common parent of the group).
168(k)(7) Election out
If a taxpayer makes an election under this paragraph with respect to any class of property for any taxable year, paragraphs (1) and (2)(F) shall not apply to any qualified property in such class placed in service during such taxable year. An election under this paragraph may be revoked only with the consent of the Secretary.
however TT will allow you to elect out on 1 property but will allow bonus for the same class on other property?
personally, since the election is made at the taxpayer level, I think TT does it wrong.
