                     Increased section 179 deduction dollar limits. The maximum amount you can elect to deduct for most section 179 property you placed in service in 2007 is $125,000 ($160,000
                        for qualified
                        enterprise zone and renewal community property). This limit is reduced by the amount by which the cost of the property placed
                        in service during the
                        tax year exceeds $500,000. See Dollar Limits under How Much Can You Deduct in chapter 2. For qualified section 179 Gulf
                        Opportunity Zone (GO Zone) property, the maximum section 179 deduction and the $500,000 threshold are increased. See Dollar limits under
                        Gulf Opportunity Zone (GO Zone) Property in chapter 2.

                        and first placed in service in 2007 is $3,060. The maximum deduction you can take for a truck or van you use in your business
                        and first placed in
                        service in 2007 is $3,260. See Maximum Depreciation Deduction in chapter 5.

                     Recovery periods for Indian Reservation property. The shorter recovery periods for qualified property placed in service on an Indian reservation applies to property placed

                        selected by the Center may appear in this publication on pages that would otherwise be blank. You can help bring these children
                        home by looking at the
                        photographs and calling 1-800-THE-LOST (1-800-843-5678) if you recognize a child.
                        
                     
                   
                  
                     
                     This publication explains how you can recover the cost of business or income-producing property through deductions for depreciation
                        (for example,
                        the special depreciation allowance and deductions under the Modified Accelerated Cost Recovery System (MACRS)). It also explains
                        how you can elect to
                        take a section 179 deduction, instead of depreciation deductions, for certain property, and the additional rules for listed
                        property.
