taxmap/pubs/p946-015.htm#en_us_publink1000142518An election to claim pre-2006 unused research credits or minimum
tax credits in lieu of claiming the special depreciation allowance ("section
168(k)(4) election") made by a corporation for either its first tax year ending
after March 31, 2008, or its first tax year ending after December 31, 2008,
continues to apply to certain extension property (as defined in section
168(k)(4)(H)), unless the corporation made an election not to apply the section
168(k)(4) election to extension property for its first tax year ending after
December 31, 2008. Generally, extension property is long production period
property and noncommercial aircraft if acquired after March 31, 2008, and placed
in service after December 31, 2009, but before January 1, 2011.
For fiscal year taxpayers with a tax year ending after December
31, 2010, an election to claim pre-2006 unused minimum tax credits in lieu of
claiming the special depreciation allowance made by a corporation for either its
first tax year ending after March 31, 2008, or its first tax year ending after
December 31, 2008, continues to apply to round 2 extension property (as defined
in section 168(k)(4)(I)), unless the corporation makes an election not to apply
the section 168(k)(4) election to round 2 extension property. If a corporation
did not make a section 168(k)(4) election for either its first tax year ending
after March 31, 2008, or its first tax year ending after December 31, 2008, the
corporation may elect for its first tax year ending after December 31, 2010, to
claim pre-2006 unused minimum tax credits in lieu of claiming the special
depreciation allowance for only round 2 extension property.
If you make an election to accelerate these credits in lieu of
claiming the special depreciation allowance for eligible property, you must not
take the 50% or 100% special depreciation allowance for the property and must
depreciate the basis in the property under MACRS using the straight line method.
See
Which Depreciation Method Applies in chapter 4.
Once made, the election cannot be revoked without IRS consent.
