What is Depreciation?

A quick overview of the basic depreciation calculations required to navigate tax laws and accounting standards properly
August 1, 2023

The tax laws and accounting standards that apply to the depreciation of business assets can be complex, confusing and difficult to decipher.  In general terms, depreciation is allowed on tangible and intangible property with a limited useful life of more than one year that is used in a trade or business or held for the production of income.

The information required for the depreciation calculations are as follows:

1. Property type – the 2 basic types of property are real and personal.  Real property includes buildings and their structural components.  Personal property includes all depreciable property other than real.

2. Service date – depreciation begins when an asset is first placed in a condition or state of readiness and availability for a specifically assigned function.

3. Useful life – the number of years that depreciable business equipment or property is expected to be in use.

4. Cost basis – depreciable basis equals acquisition cost less any salvage value.

5. Depreciation methods – how to spread the cost or other basis of an asset over its useful life.

6. First year conventions – refers to figuring how much of the cost you may depreciate the first year, based on when during that year you purchased and put the item to use in your business.

 Property Type: Real vs. Personal

  • Real Property: This includes buildings and their structural components. Actual property tax treatment under MACRS typically involves more extended recovery periods. For example, residential rental property is depreciated over 27.5 years, while non-residential real property is depreciated over 39 years.
  • Personal Property: Encompasses all depreciable assets other than real property. It includes machinery, equipment, vehicles, and even specific software. Personal property is usually subject to shorter recovery periods and can be categorized into classes (like 3-year, 5-year, or 7-year property) under MACRS.
  1. Service Date
  • The service date, or placed-in-service date, is critical in determining when depreciation begins. It marks when an asset is ready and available for its intended use. This data is essential for determining the correct tax year for forming depreciation and plays a role in determining the applicable convention for the first year.
  1. Useful Life
  • The concept of practical life is central to determining the recovery period. For MACRS, the IRS has predefined class lives for different types of assets. However, practical life can vary based on the nature of the asset, industry practices, and the business's specific usage patterns.
  1. Cost Basis
  • Determining the cost basis involves more than just the asset's purchase price. It also includes expenses necessary to acquire, transport, and set up the asset. Unlike other depreciation systems, salvage value is generally not considered in MACRS.
  1. Depreciation Methods
  • Standard methods include straight-line, declining balance, and units of production. MACRS typically uses a combination of the straight-line and declining balance methods. The selection of the technique impacts the pattern of expense recognition over the asset's life.
  1. First Year Conventions
  • These conventions determine how much depreciation can be claimed in the year the asset is placed in service. The main types are half-year, mid-quarter, and mid-month conventions. The choice of convention affects the depreciation calculation in the first and last years of the asset's recovery period.

For Experts:

  • Considerations for Changing Regulations: Keeping abreast of tax laws and accounting standards changes, such as the Tax Cuts and Jobs Act or shifts in IRS regulations, is crucial for accurate depreciation calculations.
  • Impact of Tax Policies on Depreciation Strategies: Understanding how different political climates and economic policies influence tax laws around depreciation can help in long-term tax planning and asset management.
  • Integration with Financial Reporting: Experts should consider how depreciation strategies integrate with overall financial reporting, including impacts on earnings before interest, taxes, depreciation, amortization (EBITDA), and other financial metrics.
  • Advanced Software Utilization: In-depth knowledge of how advanced features in depreciation software can optimize asset management, including scenario analysis, integration with broader financial systems, and audit trail capabilities.
