Depreciation is a key concept for firms with income tax liability, as it affects how much of a business's assets are taxed.
Depreciation is the process of allocating the cost of a tangible asset over its useful life.
The useful life of an asset is the period of time it can be used by the business.
For example, a computer might have a useful life of 5 years, while a building might have a useful life of 20 years.
The depreciation method used can impact how much a firm can claim as a tax deduction.
Straight-line depreciation, for instance, is a simple method that calculates depreciation as a fixed amount each year.
In contrast, the Modified Accelerated Cost Recovery System (MACRS) allows for accelerated depreciation, which can result in larger tax deductions in the early years of an asset's life.
Calculating Depreciation Expense
Calculating depreciation expense is a crucial step for a firm that must pay income taxes. The IRS requires that certain guidelines be followed when calculating tax depreciation.
To calculate depreciation expense, you need to determine the cost of the asset, which is the initial price of the asset. The cost of the asset is a key factor in calculating depreciation expense.
The straight line calculation steps are:
- Determine the cost of the asset.
- Subtract the estimated salvage value of the asset from the cost of the asset to get the total depreciable amount.
- Determine the useful life of the asset.
- Divide the sum of step (2) by the number arrived at in step (3) to get the annual depreciation amount.
There are four methods used for calculating depreciation: Straight line basis, declining balance, units of production, and sum-of-the-years' digits. Each method recognizes depreciation expenses differently.
The straight line depreciation formula for an asset is: (Salvage value / Useful life of asset) = Annual depreciation amount.
Depreciation Methods
There are several methods for calculating depreciation, each with its own advantages and disadvantages. The straight line method is a basic approach, but it may not accurately reflect the depreciation of an asset, especially if it loses value quickly.
The double-declining balance method is an accelerated depreciation method that results in higher depreciation expenses in the early years of an asset's life. This method is useful for assets that quickly lose value early in their useful life.
The units of production method is based on an asset's usage, activity, or units of goods produced. This method can be used to depreciate assets where variation in usage is an important factor, such as cars based on miles driven or photocopiers on copies made.
The sum-of-the-years' digits method is another accelerated depreciation method that assumes an asset will lose most of its value in the first few years of use. This method is useful for assets with a short useful life.
The declining balance method applies a higher depreciation rate in the earlier years of an asset's useful life. This method can be used to recognize more expense now and shift profit recognition further into the future.
Here are the four main methods for calculating depreciation:
- Straight line method
- Double-declining balance method
- Units of production method
- Sum-of-the-years' digits method
Each method has its own formula and requirements, but they all aim to accurately reflect the depreciation of an asset and reduce taxable income.
Depreciation and Taxes
Depreciation is a tax deduction that allows businesses to recover the cost of certain assets over time. Businesses can claim this deduction for the effective depreciation of assets such as equipment, buildings, and vehicles.
The IRS requires that certain guidelines be followed when calculating tax depreciation. The depreciation method is dictated by the IRS, and businesses must use the straight line method for assets such as office equipment and buildings.
To depreciate an asset, it must meet all of the following requirements: it must be an asset that the business owns, it must be used in a business or income-producing activity, the asset must have a determinable useful life, the asset must be expected to last more than one year, and it cannot be excepted property.
The straight line calculation steps are:
1. Determine the cost of the asset.
2. Subtract the estimated salvage value of the asset from the cost of the asset to get the total depreciable amount.
3. Determine the useful life of the asset.
4. Divide the sum of step (2) by the number arrived at in step (3) to get the annual depreciation amount.
Tax depreciation can be calculated each year, and an asset's useful life, salvage value, and tax depreciation method are factors that are considered. The IRS dictates exactly what depreciation method is required to be used depending on the assets' categorization.
Businesses are allowed to deduct a portion of the equipment's declining value from their taxes. For example, if a business owner purchases new computer equipment for $10,000 and it loses 10% of its value each year, the business owner can deduct $1,000 each year on tax return for depreciation.
Here are the four methods used for calculating depreciation:
1. Straight line basis (also called straight-line depreciation)
2. Declining balance
3. Units of production
4. Sum-of-the-years' digits
Each method recognizes depreciation expenses differently, which changes the amount by which the depreciation expense reduces a company's taxable earnings—and, therefore, its taxes.
Methods for Calculating
There are four main methods for calculating depreciation, which can significantly impact a firm's taxable income and cash flow.
The straight line method is the simplest method, where the total depreciable amount is divided by the useful life of the asset to get the annual depreciation amount.
The double-declining balance method is an accelerated method that results in higher depreciation expenses in the beginning of an asset's life and lower depreciation expenses later.
The units of production method is based on an asset's usage, activity, or units of goods produced, making it suitable for assets with varying usage, such as cars or photocopiers.
The sum-of-the-years' digits (SYD) method is another accelerated method that calculates depreciation based on the asset's production capacity in its early years.
Here are the four main methods for calculating depreciation:
The choice of method depends on the asset's characteristics, the firm's tax situation, and the desired cash flow impact.
Depreciation in Financial Statements
Depreciation expenses are found on a company's income statement, after all revenue, cost of goods sold, and operating expenses have been indicated.
It's recognized before earnings before interest and taxes (EBIT), which is used to calculate a company's tax expense.
The total amount of depreciation expenses is recognized as accumulated depreciation on a company's balance sheet.
Accumulated depreciation increases over time as monthly depreciation expenses are charged against a company's assets.
The amount of accumulated depreciation is subtracted from the gross amount of fixed assets reported.
When assets are eventually retired or sold, the accumulated depreciation amount on a company's balance sheet is reversed, removing the assets from its financial statements.
