What Is an Alternative Depreciation System (ADS)?

An alternative depreciation system (ADS) is one of the methods the Internal Revenue Service (IRS) requires taxpayers to use to determine the depreciation allowed on business assets. An ADS has a depreciation schedule with a longer recovery period that generally better mirrors the asset’s income streams than declining balance depreciation. If the taxpayer elects to use an alternative depreciation system, they must apply it to all property of the same class placed in service during the same year.

Understanding when to use ADS is important for business owners because accurately calculating depreciation expenses can help lower business taxes. However, the IRS rules regarding ADS can be complex. For this reason, many business owners opt to hire a tax professional to ensure they take as much depreciation expense as the IRS allows.

Understanding Alternative Depreciation System (ADS)

Depreciation is an accounting method that allows businesses to spread out the cost of a physical asset over a specified number of years, which is known as the useful life of the asset. The useful life of an asset is an estimate of the number of years a company will use that asset to help generate revenue. The IRS allows businesses to depreciate many kinds of business assets, including computers and peripherals; office furniture, fixtures, and equipment; automobiles; and manufacturing equipment.

Taxpayers who elect to use the alternative depreciation system feel that the alternative schedule will allow for a better match of depreciation deductions against income than the recovery period under the general depreciation system. While the ADS method extends the number of years an asset can be depreciated, it also decreases the annual depreciation cost. The depreciation amount is set at an equal amount each year with the exception of the first and last years, which are generally lower because they do not include a full twelve months.

Alternative Depreciation System (ADS) vs. General Depreciation System (GDS)

For property placed in service after 1986, the IRS requires that taxpayers use the Modified Accelerated Cost Recovery System (MACRS) to depreciate property. There are two methods that fall under the MACRS: the general depreciation system (GDS) and the alternative depreciation system (ADS).

The alternative depreciation system offers depreciation over a longer period of time than the general depreciation system, which is a declining balance method. The general depreciation system is often used by companies to depreciate assets that tend to become obsolete quickly and are replaced with newer versions on a fairly frequent basis. Computers and phone equipment are examples of this.

The general depreciation system allows companies to accelerate the asset’s depreciation rate by recording a larger depreciation amount during the early years of an asset’s useful life and smaller amounts in later years. The general depreciation system is more commonly used than the alternative depreciation system.

Special Considerations

The tax implications of calculating depreciation can affect a company’s profitability. For this reason, business owners need to carefully consider the pros and cons of ADS versus GDS. Since the alternative depreciation system offers depreciation over a longer course of time, the yearly deductions for depreciation are smaller than with the other method. Taxpayers who choose the alternative depreciation system schedule must use this schedule for all property of the same class that was placed in service during the taxable year.

However, taxpayers may elect the alternative depreciation system schedule for real estate on a property-by-property basis. The alternative depreciation system recovery schedule is listed in IRS Publication 946.

What Is the Amortization of Intangibles?

Amortization of intangibles, also simply known as amortization, is the process of expensing the cost of an intangible asset over the projected life of the asset for tax or accounting purposes. Intangible assets, such as patents and trademarks, are amortized into an expense account called amortization. Tangible assets are instead written off through depreciation. The amortization process for corporate accounting purposes may differ from the amount of amortization used for tax purposes.

Understanding the Amortization of Intangibles

For tax purposes, the cost basis of an intangible asset is amortized over a specific number of years, regardless of the actual useful life of the asset (as most intangibles don’t have a set useful life). The Internal Revenue Service (IRS) allows intangibles to be amortized over a 15-year period if it’s one of the ones included in Section 197.

Intangible assets are non-physical assets that can be assigned an economic value. Intellectual property (IP) is considered to be an intangible asset and is a broad term that encompasses most intangible assets. Most IP is covered under Section 197. Examples of these Section 197 intangible assets include patents, goodwill, trademarks, and trade and franchise names.

Not all IP is amortized over the 15-year period set by the IRS, however. There are certain exclusions, such as software acquired in a transaction that is readily available for purchase by the general public, subject to a nonexclusive license, and has not been substantially modified. In those cases and select others, the intangibles are amortized under Section 167.

Special Considerations

When a parent company purchases a subsidiary company and pays more than the fair market value (FMV) of the subsidiary’s net assets, the amount over fair market value is posted to goodwill (an intangible asset). IP is initially posted as an asset on the firm’s balance sheet when it is purchased.

IP can also be internally generated by a company’s own research and development (R&D) efforts. For instance, a company may win a patent for a newly developed process, which has some value. That value, in turn, increases the value of the company and so must be recorded appropriately.

In either case, the process of amortization allows the company to write off annually a part of the value of that intangible asset according to a defined schedule.

Amortization vs. Depreciation

Assets are used by businesses to generate revenue and produce income. Over a period of time, the costs related to the assets are moved into an expense account as the useful life of the asset dwindles. By expensing the cost of the asset over a period of time, the company is complying with GAAP, which requires the matching of revenue with the expense incurred to generate the revenue.

Tangible assets are expensed using depreciation, and intangible assets are expensed through amortization. Depreciation generally includes a salvage value for the physical asset—the value that the asset can be sold for at the end of its useful life. Amortization doesn’t take into account a salvage value.

Types of Amortization

For accounting (financial statement) purposes, a company can choose from six amortization methods: straight line, declining balance, annuity, bullet, balloon, and negative amortization. There are only four depreciation methods that can be used for accounting purposes: straight line, declining balance, sum-of-the-years’ digits, and units of production.

For tax purposes, there are two options for amortization of intangibles that the IRS allows. These are straight line and the income forecast method. The income forecast method can be used instead of the straight-line method if the asset is: motion picture films, videotapes, sound recordings, copyrights, books, or patents. For depreciation of physical assets, the IRS only allows the Modified Accelerated Cost Recovery System (MACRS).

Example of Amortization

Assume, for example, that a construction company buys a $32,000 truck to contractor work, and that the truck has a useful life of eight years. The annual depreciation expense on a straight-line basis is the $32,000 cost basis minus the expected salvage value—in this case, $4,000—divided by eight years. The annual deprecation for the truck would be $3,500 per year, or ($32,000 – $4,000) ÷ 8.

On the other hand, assume that a corporation pays $300,000 for a patent that allows the firm exclusive rights over the intellectual property for 30 years. The firm’s accounting department posts a $10,000 amortization expense each year for 30 years.

Both the truck and the patent are used to generate revenue and profit over a particular number of years. Since the truck is a physical asset, depreciation is used, and since the rights are intangible, amortization is used.

What Is Accumulated Depreciation?

Accumulated depreciation is the cumulative depreciation of an asset up to a single point in its life. Accumulated depreciation is a contra asset account, meaning its natural balance is a credit that reduces the overall asset value.

Understanding Accumulated Depreciation

The matching principle under generally accepted accounting principles (GAAP) dictates that expenses must be matched to the same accounting period in which the related revenue is generated. Through depreciation, a business will expense a portion of a capital asset’s value over each year of its useful life. This means that each year a capitalized asset is put to use and generates revenue, the cost associated with using up the asset is recorded.

Accumulated depreciation is the total amount an asset has been depreciated up until a single point. Each period, the depreciation expense recorded in that period is added to the beginning accumulated depreciation balance. An asset’s carrying value on the balance sheet is the difference between its historical cost and accumulated depreciation. At the end of an asset’s useful life, its carrying value on the balance sheet will match its salvage value.

When recording depreciation in the general ledger, a company debits depreciation expense and credits accumulated depreciation. Depreciation expense flows through to the income statement in the period it is recorded. Accumulated depreciation is presented on the balance sheet below the line for related capitalized assets. The accumulated depreciation balance increases over time, adding the amount of depreciation expense recorded in the current period.

How to Calculate Accumulated Depreciation

There are several acceptable methods for calculating depreciation. These methods are allowable under Generally Accepted Accounting Principles (GAAP). A company may select the depreciation method they wish to use.

Straight-Line Method

Under the straight-line method of accounting, a company deducts the asset’s salvage value from the purchase price to find a depreciable base. Then, this base is accumulated evenly over the anticipated useful life of the asset. The straight-line method formula is:

Annual Accumulated Depreciation = (Asset Value – Salvage Value) / Useful Life in Years

Imagine Company ABC buys a building for $250,000. The building is expected to be useful for 20 years with a value of $10,000 at the end of the 20th year. The depreciable base for the building is $240,000 ($250,000 – $10,000). Divided over 20 years, the company would recognized $20,000 of accumulated depreciation every year. 

Declining Balance Method

Under the declining balance method, depreciation is recorded as a percentage of the asset’s current book value. Because the same percentage is used in every year while the current book value decreases, the amount of depreciation decreases each year. Even though accumulated depreciation will still increase, the amount of accumulated depreciation will decrease each year.

Annual Accumulated Depreciation = Current Book Value * Depreciation Rate

For example, imagine Company ABC buys a company vehicle for $10,000 with no salvage value at the end of its life. The company decided it would depreciate 20% of the book value each year. In Year 1, Company ABC would recognize $2,000 ($10,000 * 20%) of depreciation and accumulated depreciation. In Year 2, Company ABC would recognize $1,600 (($10,000 – $2,000) * 20%).

Double-Declining Balance Method

Under the double-declining balance (also called accelerated depreciation), a company calculates what it’s depreciation would be under the straight-line method. Then, the company doubles the depreciation rate, keeps this rate the same across all years the asset is depreciated, and continues to accumulate depreciation until the salvage value is reached. The percentage can simply be calculated as twice of 100% divided by the number of years of useful life.

Double-Declining Balance Method Rate = (100% / Useful Life In Years) * 2

Double-Declining Balance Method = Depreciable Amount * Double-Declining Balance Method Rate

Let’s imagine Company ABC’s building they purchased for $250,000 with a $10,000 salvage value. Under the straight-line method, the company recognized 5% (100% depreciation / 20 years); therefore, it would use 10% as the depreciation base for the double-declining balance method. The company would recognize $24,000 ($240,000 depreciable base * 10%) in Year 1, and would recognize $21,600 (($240,000 depreciable base – $24,000) * 10%).

Sum-of-the-Years’ Digits Method

Under the sum-of-the-years’ digits method, a company strives to record more depreciation earlier in the life of an asset and less in the later years. This is done by adding up the digits of the useful years, then depreciating based on that number of year.

Annual Accumulated Depreciation = Depreciable Base * (Inverse Year Number / Sum of Year Digits)

Company ABC purchased a piece of equipment that has a useful life of 5 years. The asset has a depreciable base of $15,000. Since the asset has a useful life of 5 years, the sum of year digits is 15 (5+4+3+2+1). The depreciation rate is then the quotient of the inverse year number (Year 1 = 5, Year 2 = 4, Year 3 = 3, etc.) divided by 15. In Year 1, the company will recognize $5,000 ($15,000 * (5/15)) of depreciation and will recognize $4,000 ($15,000 * (4/15)) in Year 2.

Units of Production Method

Under the units of production method, a company estimates the total useful output of an asset. Then, the company evaluates how many of those units were consumed each year to recognize accumulated depreciation variably based on use. The formula for the units of production method is:

Annual Accumulated Deprecation = (Number of Units Consumed / Total Units To Be Consumed) * Depreciable Base

For example, a company buys a company vehicle and plans on driving the vehicle 80,000 miles. In the first year, the company drove the vehicle 8,000 miles. Therefore, it would recognize 10% (8,000 / 80,000) of the depreciable base. In the second year, if the company drives 20,000 miles, it would recognize 25% of depreciable base as an expense in the second year, with accumulated depreciation now equal to $28,000 ($8,000 in the first year + $20,000 in the second year).

Accumulated Depreciation vs. Accelerated Depreciation

Though similar sounding in name, accumulated depreciation and accelerated depreciation refer to very different accounting concepts. Accumulated depreciation refers to the life-to-date depreciation that has been recognized that reduces the book value of an asset. On the other hand, accelerated depreciation refers to a method of depreciation where a higher amount of depreciation is recognized earlier in an asset’s life.

Since accelerated depreciation is an accounting method for recognizing depreciation, the result of accelerated depreciation is to book accumulated depreciation. Under this method, the amount of accumulated depreciation accumulates faster during the early years of an asset’s life and accumulates slower later. The philosophy behind accelerated depreciation is assets that are newer (i.e. a new company vehicle) are often used more than older assets because they are in better condition and more efficient. 

Accumulated Depreciation vs. Depreciation Expense

When an asset is depreciated, two accounts are immediately impacted: accumulated depreciation and depreciation expense. The journal entry to record depreciation results in a debit to depreciation expense and a credit to accumulated depreciation. The dollar amount for each line is equal to the other.

There are two main differences between accumulated depreciation and depreciation expense. First, depreciation expense is reported on the income statement, while accumulated depreciation is reported on the balance sheet. 

Second, on a related note, the income statement does not carry from year-to-year. Activity is swept to retained earnings, and a company “resets” its income statement every year. Meanwhile, its balance sheet is a life-to-date running total that does not clear at year-end. Therefore, depreciation expense is recalculated every year, while accumulated depreciation is always a life-to-date running total.

Special Considerations

Accounting Adjustments/Changes in Estimate

Because the depreciation process is heavily rooted with estimates, it’s common for companies to need to revise their guess on the useful life of an asset’s life or the salvage value at the end of the asset’s life. This change is reflected as a change in accounting estimate, not a change in accounting principle. For example, say a company was depreciating a $10,000 asset over its five year useful life with no salvage value. Using the straight-line method, accumulated depreciation of $2,000 is recognized.

After two years, the company realizes the remaining useful life is not three years but instead six years. Under GAAP, the company does not need to retroactively adjust financial statements for changes in estimates. Instead, the company will change the amount of accumulated depreciation recognized each year. 

In this example, since the asset now has a $6,000 net book value ($10,000 purchase price less $4,000 of accumulated depreciation booked in the first two years), the company will now recognized $1,000 of accumulated depreciation for the next six years. 

Half-Year Recognition

A commonly practiced strategy for depreciating an asset is to recognize a half year of depreciation in the year an asset is acquired and a half year of depreciation in the last year of an asset’s useful life. This strategy is employed to more fairly allocate depreciation expense and accumulated depreciation in years when an asset may only be used part of a year. 

For example, Company A buys a company vehicle in Year 1 with a five year useful life. Regardless of the month, the company will recognize six months worth of depreciation in Year 1. The company will also recognize a full year of depreciation in Year 2 – 5. Then, the company will recognize the final half year of depreciation in Year 6. Although the asset only had a useful life of five years, it is argued that the asset wasn’t used for the entirety of Year 1 nor the entirety of Year 6.

Example of Accumulated Depreciation

Company A buys a piece of equipment with a useful life of 10 years for $110,000. The equipment is estimated to have a salvage value of $10,000. The equipment is going to provide the company with value for the next 10 years, so the company expenses the cost of the equipment over the next 10 years. Straight-line depreciation is calculated as (($110,000 – $10,000) / 10), or $10,000 a year. This means the company will depreciate $10,000 for the next 10 years until the book value of the asset is $10,000.

Each year the contra asset account referred to as accumulated depreciation increases by $10,000. For example, at the end of five years, the annual depreciation expense is still $10,000, but accumulated depreciation has grown to $50,000. That is, accumulated depreciation is a cumulative account. It is credited each year as the value of the asset is written off and remains on the books, reducing the net value of the asset, until the asset is disposed of or sold. It is important to note that accumulated depreciation cannot be more than the asset’s historical cost even if the asset is still in use after its estimated useful life.

The Bottom Line

Many companies rely on capital assets such as buildings, vehicles, equipment, and machinery as part of their operations. In accordance with accounting rules, companies must depreciate these assets over their useful lives. As a result, companies must recognize accumulated depreciation, the sum of depreciation expense recognized over the life of an asset. Accumulated depreciation is reported on the balance sheet as a contra asset that reduces the net book value of the capital asset section. 

What Is Accelerated Depreciation?

Accelerated depreciation is any method of depreciation used for accounting or income tax purposes that allows greater depreciation expenses in the early years of the life of an asset. Accelerated depreciation methods, such as double-declining balance (DDB), means there will be higher depreciation expenses in the first few years and lower expenses as the asset ages. This is unlike the straight-line depreciation method, which spreads the cost evenly over the life of an asset.

Understanding Accelerated Depreciation

Accelerated depreciation methods tend to align the recognized rate of an asset’s depreciation with its actual use, although this isn’t technically required. This alignment tends to occur because an asset is most heavily used when it’s new, functional, and most efficient. 

Because this tends to occur at the beginning of the asset’s life, the rationale behind an accelerated method of depreciation is that it appropriately matches how the underlying asset is used. As an asset age, it is not used as heavily, since it is slowly phased out for newer assets.

Special Considerations

Using an accelerated depreciation method has financial reporting implications. Because depreciation is accelerated, expenses are higher in earlier periods compared to later periods. Companies may utilize this strategy for taxation purposes, as an accelerated depreciation method will result in a deferment of tax liabilities since income is lower in earlier periods.

Alternatively, public companies tend to shy away from accelerated depreciation methods, as net income is reduced in the short-term.

Types of Accelerated Depreciation Methods

Double-Declining Balance Method  

The double-declining balance (DDB) method is an accelerated depreciation method. After taking the reciprocal of the useful life of the asset and doubling it, this rate is applied to the depreciable base—also known as the book value, for the remainder of the asset’s expected life.

For example, an asset with a useful life of five years would have a reciprocal value of 1/5 or 20%. Double the rate, or 40%, is applied to the asset’s current book value for depreciation. Although the rate remains constant, the dollar value will decrease over time because the rate is multiplied by a smaller depreciable base each period.

Sum of the Years’ Digits (SYD)

The sum-of-the-years’-digits (SYD) method also allows for accelerated depreciation. To start, combine all the digits of the expected life of the asset. For example, an asset with a five-year life would have a base of the sum-of-the-digits one through five, or 1 + 2 + 3 + 4 + 5 = 15. 

In the first depreciation year, 5/15 of the depreciable base would be depreciated. In the second year, only 4/15 of the depreciable base would be depreciated. This continues until year five depreciates the remaining 1/15 of the base.
