Depreciation and Amortization: Squeezing the Gap Between Accounting and Tax Accounting

For business owners, accountants, and tax professionals alike, two terms that tend to generate as much curiosity as confusion are depreciation and amortization. While they’re both standard tools in accounting and taxation, their applications and reasons for use can be vastly different. 

At KMK Ventures, we believe that we can simplify these financial complexities for businesses throughout the U.S. What follows is a breakdown of what depreciation and amortization are, how they work in your accounting records, how they impact your tax returns, and what you should know to make informed, compliant decisions. 

What Are Depreciation and Amortization? 

Depreciation and amortization are bookkeeping techniques to spread the cost of an asset over its useful life. 

• Depreciation is applied to tangible fixed assets (such as buildings, vehicles, and machinery). 

• Amortization is applied for intangible assets (such as patents, goodwill, or software licenses). 

These techniques help provide a more accurate financial picture and ensure that expenses are aligned with the income they generate. 

Depreciation and Amortization in Your Books 

From an accounting for financial purposes (i.e., “book accounting”), the objective is to reflect an accurate and fair view of your business’s performance and financial situation. 

Book Depreciation: 

• Assets are depreciated according to their assumed useful life. 

• Most common methods: 

• Straight-Line: Equal annual expense 

• Declining Balance: Greater expense in early years 

• Units of Production: Based on usage or production 

• The cost is accounted for monthly or annually in your Profit & Loss (P&L) and decreases the asset value on the balance sheet. 

Amortization in the Books: 

• Used primarily on intangible assets with a limited life (e.g., a 10-year software license). 

• Usually employs the straight-line approach over the useful life of the asset. 

• Similar to depreciation, amortization cost is reflected on the profit and loss (P&L) statement and decreases the asset value on the balance sheet. 

Depreciation and Amortization for Tax Purposes 

For taxes, IRS regulations under the U.S. tax code dictate how assets are amortized and depreciated. 

Key Tax Treatment Differences: 

1. Purpose: Taxes are not about “true and fair view” but instead reducing taxable income via permissible deductions. 
2. Methods & Rates: The IRS typically uses the Modified Accelerated Cost Recovery System (MACRS) instead of the straight-line depreciation method. 
3. Bonus Depreciation and Section 179: Expensing permits firms to deduct most of the costs of assets in the initial year. 

Example to Understand the Gap 

Assume you purchased equipment for $100,000. 

• You depreciate it in your books over 10 years with the straight-line method and expense $10,000 a year. 

• For tax purposes, according to IRS guidelines, you may depreciate it over 5 years using MACRS or deduct the entire $100,000 in year 1 under Section 179. 

Outcome: Your book profit and taxable income will be different, particularly in the initial years. 

Typical IRS Forms Involved with Depreciation & Amortization: 

• Form 4562 – Used to report depreciation and amortization on your federal tax return. 

• Form 4797 – To report the sale of business property and compute gains/losses with depreciation recapture. 

Mistakes to Avoid 

1. Having books and tax done the same way – You can, but you don’t need to. Having them separate tends to keep profits and taxes under control. 
2. Failing to record asset purchases correctly – Omitting the date of purchase, cost, or type of asset can cause mistakes in both books and tax returns. 
3. Forgetting amortization of intangible assets – Companies often overlook this, even though software, trademarks, and goodwill can provide substantial deductions. 
4. Misusing Section 179 – This valuable tax deduction has limits and specific qualifying requirements. Misuse can lead to IRS attention.

Book vs. Tax Depreciation: What Should You Track? 

Both! Maintaining two separate depreciation schedules —one for bookkeeping and one for tax —ensures compliance while enabling efficient planning. 

This method also facilitates reconciling your GAAP-reported financials with your tax filings to the IRS, particularly crucial if you’re raising capital, being audited, or selling out.
