Tax Impact of Accelerated Depreciation

Accelerated depreciation allows businesses to write off the cost of an asset more quickly than the straight-line method, which spreads the cost evenly over the asset’s useful life. The tax impact of accelerated depreciation can be significant for businesses, especially in the early years of an asset’s life. Here are the primary tax implications:

Example of the Tax Impact of Accelerated Depreciation

Let’s illustrate the tax impact of accelerated depreciation with a hypothetical scenario:

Scenario:

Imagine XYZ Manufacturing purchases a new machine for $100,000. The machine has a useful life of 5 years. XYZ Manufacturing has the option to use straight-line depreciation or an accelerated depreciation method. Let’s consider the Double Declining Balance (DDB) method as our accelerated option. Assume the corporate tax rate for XYZ Manufacturing is 30%.

Straight-Line Depreciation:

Each year, XYZ Manufacturing would deduct $20,000 ($100,000 ÷ 5 years) from its taxable income.

Double Declining Balance:

  • Year 1: 2/5 of $100,000 = $40,000
  • Year 2: 2/5 of ($100,000 – $40,000) = $24,000
  • Year 3: 2/5 of ($60,000 – $24,000) = $14,400
  • Year 4: 2/5 of ($35,600 – $14,400) = $8,480
  • Year 5: Remaining balance = $2,720

Tax Implications:

For the sake of simplicity, assume the only expense XYZ Manufacturing has is this depreciation.

  • Year 1:
    • Straight-Line: Taxable income reduced by $20,000. Tax saved = $20,000 * 30% = $6,000
    • DDB: Taxable income reduced by $40,000. Tax saved = $40,000 * 30% = $12,000
  • Year 2:
    • Straight-Line: Tax saved = $20,000 * 30% = $6,000
    • DDB: Tax saved = $24,000 * 30% = $7,200

Let’s evaluate over the asset’s entire useful life:

Total Tax Savings Over 5 Years:

  • Straight-Line: $6,000 * 5 = $30,000
  • DDB: $12,000 + $7,200 + ($14,400 * 30%) + ($8,480 * 30%) + ($2,720 * 30%) = $12,000 + $7,200 + $4,320 + $2,544 + $816 = $26,880

Outcome:

  • In the early years (specifically Year 1 in our example), the company saves more in taxes using the DDB method compared to the straight-line.
  • However, over the entire life of the asset, the total tax saved with DDB is slightly less than the straight-line, because the company gets smaller tax deductions in the later years using DDB.

This example illustrates that while accelerated depreciation methods can offer substantial tax savings in the initial years of an asset’s life, the cumulative tax savings over time might be less compared to straight-line. However, the immediate liquidity provided by the upfront tax savings can be invaluable for certain companies, especially those in capital-intensive industries or startups with significant capital expenditures.
