What Is Annual Depreciation Allowance?


An annual depreciation allowance refers to the deduction permitted by tax authorities for taxpayers to subtract from their taxable income regarding assets subject to depreciation.

In the U.S. tax regulations, the Internal Revenue Service (IRS) authorizes homeowners and investors to diminish their tax liabilities for properties expected to lose value over time. This depreciation reflects the eroding marketability and the increased maintenance expenses associated with aging properties.

How It Works

When you purchase a property for investment purposes, the IRS considers it a capital asset. Unlike other expenses incurred during property ownership — such as maintenance and repairs — depreciation is not a cash outflow. Instead, it is a non-cash expense that accounts for the gradual loss in asset value over time.

Even the most well-constructed properties inevitably gain wear and tear over the years. The IRS allows property owners to deduct a portion of the property’s value each year as depreciation. This deduction is spread out over the useful life of the property, as determined by the IRS guidelines for different types of assets. For residential real estate, the useful life is generally 27.5 years, while commercial real estate has a useful life of 39 years.

Most forms of tangible property — excluding land — fall under depreciable assets. These include structures, machinery, automobiles, office furnishings, and equipment. Additionally, you can depreciate select intangible assets, such as patents, copyrights, and software solutions. For an asset to qualify for depreciation, it must meet several criteria:

  • The asset must be your property.
  • It must be employed in your business or as part of an income-generating activity.
  • It should have a lifespan that can be specifically measured.
  • It is expected to serve a purpose for more than one year.

Significance for Real Estate Investors

In real estate investment, understanding the concept of annual depreciation allowance is crucial. Here are the significant benefits for real estate investors:

  • Tax Deduction Advantage: The annual depreciation allowance allows real estate investors to claim a deduction for the decrease in the property’s value each year, reducing annual taxable income.
  • Cash Flow Boost: Depreciation is a paper loss, meaning it does not affect the actual cash flow of the investor. Investors can retain more revenue by claiming depreciation, increasing their available cash on hand.
  • Improving ROI: By lowering taxable income, the depreciation allowance effectively enhances the property’s return on investment (ROI).
  • Strategy for Reinvestment: The savings garnered from depreciation can expand an investor’s portfolio and potentially lead to further tax reduction mechanisms, continuing the cycle of investment growth.

How To Calculate Annual Depreciation Allowance

There are different methods to calculate depreciation, but the straight-line method is the most common for real estate. Under this method, you calculate the annual depreciation expense by dividing the property’s purchase price (or adjusted basis) by its useful life.

For example, if you purchased a rental property for $300,000, and the IRS assigns a useful life of 27.5 years, the annual depreciation expense would be approximately $10,909 ($300,000 / 27.5).

As another example, if you acquired a commercial building for $1,000,000 with a useful life of 39 years, the annual depreciation expense would be approximately $25,641 ($1,000,000 / 39).

Considerations and Limitations

While annual depreciation allowance offers substantial tax benefits, there are some considerations and limitations to keep in mind:

  • Recapture Tax: Any depreciation claimed over the years is subject to recapture tax when you sell a property.
  • Depreciation Must Be Recaptured Upon Sale: This rule can impact the after-tax proceeds from the sale and should be considered when planning an exit strategy.
  • Depreciation Recovery Periods: Property components — such as buildings, land improvements, and furnishings — may have different depreciation recovery periods.

Annual Depreciation Allowance Tips for Real Estate Investors

Understanding the intricacies of the annual depreciation allowance can significantly impact your real estate investment strategy. As you navigate through the complex tax implications, consider the following tips to maximize your benefits:

  • Keep meticulously detailed records of your property’s purchase price, any capital improvements, and all depreciation claims over the years.
  • Regularly consult with a tax advisor to align your depreciation strategies with current tax legislation and explore additional opportunities for tax savings.
  • Factor in the possibility of tax reform and how changes in the law might affect your future return on investment, adjusting your strategies as necessary. 
  • Consider conducting a cost segregation study, which can allow for accelerated depreciation deductions and potentially enhance cash flow.
  • Beware of potential recapture tax implications and plan accordingly when selling a property.

The Bottom Line

Annual depreciation allowance is a fundamental concept in real estate investment, providing investors with valuable tax benefits and improving overall cash flow. By understanding how depreciation works and maximizing its benefits within tax regulations, investors can optimize returns and build wealth through real estate ownership.
