Faster write-offs for certain capital expenditures

The American Recovery and Reinvestment Act (ARRA), enacted in February 2009, extended the bonus depreciation and increased the section 179 deduction. Many small businesses that invest in new property and equipment will be able to write off most or all of these purchases on their 2009 returns. 

A new IRS.gov [1] page has more information on the bonus depreciation and increased Section 179 deduction.
