When a business invests in long-term assets, it can't deduct the entire cost in the year of purchase. Instead, it recovers the cost over time. For tangible assets, such as machinery or buildings, this process is known as depreciation. For natural resources, it's called depletion. And for intangible assets, it's called amortization.
Amortization is the method of deducting the capitalized cost of certain intangible assets in equal amounts over a set period. Understanding which costs must be amortized is crucial for any business that invests in assets such as startup activities, intellectual property, or franchise rights. This guide explains what amortization is, the costs it applies to, and how to report it correctly for tax compliance purposes.
Amortization is not a direct expense category that you choose for a specific payment. It is a calculated, non-cash deduction that represents the annual write-off of a previously capitalized cost. The costs that are amortized are capital expenditures for intangible assets that provide a benefit to the business for more than one year.
The annual amortization deduction is calculated on Form 4562, and the total is then carried to your main business tax return.
The key to amortization is identifying which business costs must be capitalized and recovered over time, rather than deducted immediately.
IRS Publication 535 outlines several types of costs that must be amortized over time. These include:
Unlike depreciation, which has various recovery periods, amortization periods are generally fixed by the tax code. For example, Section 197 intangibles have a mandatory 15-year (180-month) amortization period, regardless of their actual useful life.
The annual amortization deduction is calculated and reported on Form 4562, Part VI, Amortization. The total from this form is then carried to the appropriate line on your business tax return (e.g., Schedule C, Line 13, for a sole proprietor).
To substantiate your amortization deductions, you must have clear records of the initial capitalized cost. This includes:
Fyle is essential for the first, most critical step of amortization: capturing and correctly categorizing the initial capital expenditure.
