Depreciation & Section 179 Explained

 Depreciation and Section 179 Deductions can be a challenging aspect of one's business accounting and tax return.  The regulations regarding these deductions can be complex.  Despite the complexity, general definitions and rules are provided below:

Depreciation defined

Depreciation - for assets with a useful life of greater than 1 year, an annual depreciation expense is available for each year of an asset's useful life.  Assets would include office furniture, vehicles, buildings, intangible assets, machinery, tools, etc. Each one of these assets has a recovery period (useful life) for which an expense can be taken.  Below are examples of various assets and their recovery periods per the IRS:


Office furniture                     7 years

Automobiles                          5 years

Appliances                             5 years

Residential Rental Prop     27.5 years

Computers                             5 years

Normally, these assets would be depreciated over its recovery period.  For example, an appliance costing $2000 and depreciated over 5 years would experience a $400 deduction each year for 5 years.


Section 179 defined

Section 179 deduction -  refers to expensing an asset on one's tax return in its first year (deducting its entire cost) rather than depreciating it over its useful life.  The IRS provides guidelines on when this is permissible and what the limitations are.  You can find information on Section 179 and other depreciation information  here.  


The use of 179 deduction for an asset in its first year is illustrated below in a simple example to reflect tax savings:

Purchase of asset:

Office computer                 $5000   (Purchased 1/1)

First year depreciation        1000     (5 year property)

179 Deduction                    5000

The 179 Deduction provides tax savings of:     5000

                                                                              .22   (tax bracket)

                                                                          1100    Tax savings


For businesses with frequent turnover of assets, a strategy of when to use Section 179 with asset purchases and when not to use it can provide optimal tax savings over the long term.  However, a point should be made regarding 179 deduction:   if an asset has been expensed using Section 179 and it is disposed (sold, donated to a charity, given away, etc) before its useful life has passed (example:  a computer disposed of before 5 years when it had been expensed by 179), the item is subject to depreciation recapture. This means the item needs to recapture the depreciation taken before it would have been fully depreciated had it not been expensed with 179.  The recaptured depreciation is added back on one's tax return in the year of disposal.
