Can You Depreciate Software for Tax Purposes?

Depreciation allows businesses to spread an asset’s cost over its estimated useful life. This accounting method recognizes that assets provide economic benefits over multiple years, with their value declining due to use or obsolescence. For tax purposes, depreciation reduces a business’s taxable income, reflecting the ongoing expense of asset wear and tear. Computer software, an increasingly important business asset, can qualify for this tax treatment.

Qualifying Software for Depreciation

Software depreciation depends on its type. Off-the-shelf software, such as standard accounting programs or word processors, is considered an intangible asset. When purchased outright, this software is eligible for depreciation as it represents a capital expenditure providing benefits beyond one year.

Custom-developed software follows different rules. For tax years beginning after December 31, 2021, development costs, including labor and testing, must be capitalized and amortized. This amortization period is five years for domestic development or fifteen years for foreign development. This requires businesses to spread these costs over several years rather than expensing them immediately.

Software licensed for use, rather than purchased outright, is treated differently. Subscription fees for Software as a Service (SaaS) or cloud-based software are considered ordinary business operating expenses. These recurring fees are deducted in the year they are paid or accrued, as businesses do not own the underlying software asset.

When software is an integral part of hardware, and its cost is not separately stated, it is depreciated along with the hardware. In such cases, the software’s cost is treated as part of the hardware’s overall cost, and its depreciation follows the rules applicable to the tangible asset.

General Requirements for Depreciation

To be eligible for depreciation, software must meet several general requirements. The business must own the software or possess a qualifying interest, distinguishing it from merely licensing or subscribing to a service. Ownership ensures the business bears the economic burden of the asset’s decline in value.

The software must be used in a trade or business or for the production of income. Software used for personal activities does not qualify for tax depreciation, and if used for both business and personal purposes, only the business portion is depreciable. This requirement ensures that only expenses related to income-generating activities receive tax benefits.

A determinable useful life is another necessary criterion; the software must have an estimable period of utility that extends beyond one year. For most computer software, tax regulations assign a useful life of 36 months for depreciation. Finally, the software must be subject to wear and tear, decay, or obsolescence, reflecting its diminishing value. The cost must be capitalized, rather than expensed in the year of purchase, to be depreciated over its useful life.

Standard Depreciation Methods

Once software qualifies for depreciation and meets general requirements, businesses can apply standard methods to calculate the annual deduction. The straight-line method is a common approach for depreciating software, spreading the asset’s cost evenly over its useful life. This method provides a consistent deduction each year, simplifying tax planning.

For tax purposes, most purchased computer software is assigned a useful life of 36 months. While the Modified Accelerated Cost Recovery System (MACRS) primarily applies to tangible property, IRS guidance dictates the recovery period for intangible assets like software. This 3-year period is used as the basis for calculating annual depreciation deductions.

To calculate the annual depreciation deduction using the straight-line method, the depreciable cost of the software is divided by its useful life in years. For example, if software costs $3,000 and has a 3-year useful life, the annual depreciation deduction would be $1,000. This deduction reduces the business’s taxable income each year.

Depreciation begins in the tax year the software is “placed in service,” meaning it is ready and available for its assigned function. Even if purchased at year-end, a portion of the depreciation can be claimed for that tax year. This “placed in service” rule ensures deductions are taken when the asset begins its productive use.

Accelerated Depreciation Options

Businesses can utilize accelerated depreciation options to deduct a larger portion of qualifying software costs in initial years. The Section 179 deduction allows businesses to expense the full cost of certain purchased off-the-shelf software in the year it is placed in service, rather than depreciating it. This provision aims to incentivize investment by providing immediate tax relief.

For tax years beginning in 2024, the maximum Section 179 expense deduction is $1,220,000, with a phase-out threshold starting at $3,050,000 of qualifying property placed in service. For tax years beginning in 2025, the maximum deduction increases to $1,250,000, and the phase-out threshold begins at $3,130,000. The deduction is reduced dollar-for-dollar for amounts exceeding the phase-out threshold, primarily benefiting small and medium-sized businesses.

Bonus depreciation also provides an accelerated deduction for qualifying new and used software. This allowance permits businesses to deduct a significant percentage of the software’s cost in the first year it is placed in service. The bonus depreciation rate is 60% for property placed in service in 2024, decreasing to 40% for 2025, and then to 20% for 2026, before phasing out entirely for property placed in service in 2027 and beyond.

Both Section 179 and bonus depreciation have specific eligibility requirements and annual limits, and Section 179 can only be taken up to the amount of the business’s taxable income. Businesses may choose to use one or both of these provisions, depending on their specific tax situation and investment strategy. The ability to accelerate deductions can significantly improve cash flow by reducing the tax burden in the year of purchase.
