Amortization is a method used in U.S. tax law to recover the cost of certain intangible assets and specified capitalized costs over a fixed period, rather than deducting the full amount in the year incurred. It operates similarly to straight-line depreciation but applies primarily to intangible property. Common items subject to amortization include Section 197 intangibles (such as goodwill, trademarks, and franchises), business startup costs and reforestation costs.
Key Amortization Rules and Applications
- Business Startup Costs: Taxpayers may elect to deduct up to $5,000 of startup costs in the first year (subject to a phase-out if total costs exceed $50,000). Any remaining costs must be amortized over 180 months (15 years), beginning with the month the active trade or business starts.
- Section 197 Intangibles: Capitalized costs of Section 197 intangibles acquired after August 10, 1993, must be amortized over 15 years (180 months) if held in connection with a trade or business or income-producing activity. No other depreciation or amortization is allowed for these assets.
- Reforestation Costs: These costs are eligible for amortization, generally over an 84-month period, with a limited immediate deduction allowed subject to applicable rules.
Reporting Amortization on Tax Forms
- Form 4562, Part VI: Used to report amortization deductions. Taxpayers must complete columns for description of costs (a), date amortization begins (b), amortizable amount (c), applicable Code section (d), and the amortization deduction for the year (f). The deduction is calculated by dividing the amortizable amount by the total months in the amortization period and multiplying by the number of months in the tax year, or by using the applicable percentage.
- Prior Year Costs: If amortizing costs that began before the current tax year and there is no other requirement to file Form 4562, the deduction may be reported directly on the appropriate Other Deductions or Other Expenses line of the return.
- Reporting Total: Total amortization is reported on the applicable deduction line of the return. For partnerships and S corporations, certain items (such as reforestation amortization) must be separately stated on Schedules K and K-1.
Bond Premium Amortization
- Bonds Acquired Before October 23, 1986: Amortization of bond premium is treated as a miscellaneous itemized deduction not subject to the 2% of AGI floor. (Publication 550, Section: Investment Expenses | Bond Premium Amortization | Bonds acquired before October 23, 1986)
- Bonds Acquired After October 22, 1986, but Before 1988: Amortization is treated as investment interest expense subject to investment interest limits unless treated as an offset to interest income. (Publication 550, Section: Investment Expenses | Bond Premium Amortization | Bonds acquired after October 22, 1986, but before 1988)
- Constant Yield Method: For bonds issued after September 27, 1985, premium must be amortized using the constant yield method based on yield to maturity. The yield is determined as of the date of acquisition and must be constant over the bond’s term.
