Increased expensing for small business depreciable assets

Explanation of Provision

The provision provides that the maximum amount a taxpayer may expense, for taxable years beginning in 2012 and 2013, is $500,000 of the cost of qualifying property placed in service for the taxable year. The $500,000 amount is reduced (but not below zero) by the amount by which the cost of qualifying property placed in service during the taxable year exceeds $2,000,000.

In addition, the provision extends, for taxable years beginning in 2013, the treatment of off-the-shelf computer software as qualifying property. The provision also extends the treatment of qualified real property as eligible section 179 property for taxable years beginning in 2012 and 2013, including the limitation on carryovers and the maximum amount of $250,000 for each taxable year. The provision makes a technical drafting correction by clarifying that for the last taxable year beginning in 2013, the taxable income limitation 436 is computed without regard to any additional depreciation expense resulting from the application of the carryover limitation of section 179(f)(4). For taxable years beginning in 2013, the provision continues to permit a taxpayer to amend or irrevocably revoke an election for a taxable year under section 179 without the consent of the Commissioner.

In addition, the provision extends the treatment of off-the-shelf computer software as qualifying property,1606 as well as the provision permitting a taxpayer to amend or irrevocably revoke an election for a taxable year under section 179 without the consent of the Commissioner for one year (through 2012).

For taxable years beginning in 2013, and thereafter, the maximum amount a taxpayer may expense is $25,000 of the cost of qualifying property placed in service for the taxable year.

Increase and expand expensing of certain depreciable business assets

Explanation of Provision

The provision increases the maximum amount a taxpayer may expense under section 179 to $500,000 and increases the phase-out threshold amount to $2 million for taxable years beginning in 2010 and 2011.1334 Thus, the provision provides that the maximum amount a taxpayer may expense, for taxable years beginning after 2009 and before 2012, is $500,000 of the cost of qualifying property placed in service for the taxable year. The $500,000 amount is reduced (but not below zero) by the amount by which the cost of qualifying property placed in service during the taxable year exceeds $2 million.

The provision permits a taxpayer to elect to temporarily expand the definition of property qualifying for section 179 to include certain real property—specifically, qualified leasehold improvement property, qualified restaurant property, and qualified retail improvement property—purchased by the taxpayer.1335 The maximum amount with respect to real property that may be expensed under the proposal is $250,000.1336 In addition, section 179 deductions attributable to qualified real property that are disallowed under the trade or business income limitation may only be carried over to taxable years in which the definition of eligible section 179 property includes qualified real property. Thus under the provision, if a taxpayer’s section 179 deduction for 2010 with respect to qualified real property is limited by the taxpayer’s active trade or business income, such disallowed amount may be carried over to 2011 in the manner under present law. Any such amounts that are not used in 2011, plus any 2011 disallowed section 179 deductions attributable to qualified real property, are treated as property placed in service in 2011 for purposes of computing depreciation. The carryover amount from 2010 is considered placed in service on the first day of the 2011 taxable year.1337
