The entire acquisition cost of a computer purchased for business use can be expensed under Code section 179 in the first year if qualified, or depreciated over a 5-year recovery period. Under section 179, you can elect to recover all or part of the cost of certain qualifying property, up to a dollar limit, by deducting it in the year you place the property in service. You can elect to expense the cost of qualifying property instead of recovering the cost by taking depreciation.

Depreciation and Section 179 Deduction

The maximum section 179 deduction you can elect for qualified section 179 property placed in service in 2007 has increased to $125,000 ($160,000, for qualified zone and qualified renewal property). This limit is reduced by the amount by which the cost of qualified section 179 property placed i n service during the tax year exceeds $500,000. For qualified section 179 Gulf Opportunity (Go) Zone property, the maximum section 179 deduction is higher than the deduction for most other section 179 property.

Only property used in a trade or business or in an income producing activity can only be depreciated. Additionally, the property must be something that wears out or becomes obsolete and it must have a determinable useful life substantially beyond the tax year. The kinds of property that can be depreciated include, but are not limited to, machinery, equipment, buildings, vehicles, and furniture. Some intangible property may also be depreciable (e.g. patents). Depreciation is a complex topic.
