What Is Intangible Amortization?
Intangible amortization is an accounting technique used to gradually reduce the book value of an intangible asset over its useful or legal life. Instead of deducting the entire cost of a valuable non-physical asset in the year you acquire it, amortization spreads that cost out over several years. This is important because many intangible assets, like a purchased customer list or a patent, provide economic benefits to your business for more than just one year. By amortizing the cost, you're better matching the expense of the asset with the revenues or benefits it helps generate, giving a clearer picture of your business's true profitability each year.
The IRS has specific rules for how and when you can amortize certain intangible assets for tax purposes, primarily under Internal Revenue Code (IRC) Section 197. These are often called "Section 197 intangibles." Examples include goodwill, going concern value, workforce in place, business rights, client relationships, patents, copyrights, and trademarks acquired as part of a business purchase. For tax purposes, most Section 197 intangibles are amortized using the straight-line method over a uniform 15-year period, regardless of their actual economic life. This differs from book accounting (GAAP), where the amortization period might align with the asset's actual useful life, and some intangibles like goodwill are not amortized but tested for impairment. This difference means your tax books and your financial statements might show different figures for the same assets.
