You can take a special depreciation allowance to recover part of the cost of qualified property (defined next), placed in service during the tax year. The allowance applies only for the first year you place the property in service. For qualified property placed in service in 2012, you can take an additional 50% (or 100%, if applicable) special allowance. The allowance is an additional deduction you can take after any section 179 deduction and before you figure regular depreciation under MACRS for the year you place the property in service.
This chapter explains what is qualified property. It also includes rules regarding how to figure an allowance, how to elect not to claim an allowance, and when you must recapture an allowance.

See chapter 6 for information about getting publications and forms.

An election made by a corporation to claim pre-2006 unused minimum tax credits in lieu of claiming the special depreciation allowance 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)(iv)), 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.
For fiscal year taxpayers with a tax year ending after December 31, 2012, an election made by a corporation to claim pre-2006 unused minimum tax credits in lieu of claiming the special depreciation allowance for either its first tax year ending after March 31, 2008, its first tax year ending after December 31, 2008, or its first tax year ending after December 31, 2010, continues to apply to round 3 extension property (as defined in section 168(k)(4)(J)(iv)), unless the corporation makes an election not to apply the section 168(k)(4) election to round 3 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, its first tax year ending after December 31, 2008, or its first tax year ending after December 31, 2010, the corporation may elect for its first tax year ending after December 31, 2012, to claim pre-2006 unused minimum tax credits in lieu of claiming the special depreciation allowance for only round 3 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.
Figure the special depreciation allowance by multiplying the depreciable basis of the qualified property by 50% (or 100% if applicable). For certain qualified property placed in service after September 8, 2010, multiply the depreciable basis by 100%. For qualified reuse and recycling property, qualified cellulosic biofuel plant property, qualified disaster assistance property, and certain qualified property acquired after December 31, 2007, multiply the depreciable basis by 50%.
For qualified property other than listed property, enter the special allowance on line 14 in Part II of Form 4562. For qualified property that is listed property, enter the special allowance on line 25 in Part V of Form 4562.

Example.
On November 1, 2012, Tom Brown bought and placed in service in his business qualified property that cost $450,000. He did not elect to claim a section 179 deduction. He deducts 50% of the cost ($225,000) as a special depreciation allowance for 2012. He uses the remaining $225,000 of cost to figure his regular MACRS depreciation deduction for 2012 and later years.
You can elect, for any class of property, not to deduct any special 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.

When you dispose of property for which you claimed a special depreciation allowance, any gain on the disposition is generally recaptured (included in income) as ordinary income up to the amount of the special depreciation allowance previously allowed or allowable. See When Do You Recapture MACRS Depreciation in chapter 4 or more information.
