What Is Amortization? Tax and Accounting Guide

What Is Amortization?

Amortization is the systematic recovery or allocation of a cost over a specified period. In tax and business accounting, it commonly applies to intangible assets and certain deferred costs. In lending, an amortization schedule instead divides loan payments between principal and interest. Those meanings are related mathematically but have different tax consequences.

For an asset, amortization resembles depreciation: both spread basis over time. Depreciation generally applies to tangible property such as equipment and buildings. Amortization commonly applies to intangibles such as acquired goodwill, customer-based intangibles, trademarks, and certain start-up or organizational costs.

Not every intangible uses the same rule

The recovery period depends on the specific cost and governing tax provision. Common categories include:

• Acquired Section 197 intangibles, generally amortized over 15 years
• Business start-up costs under Section 195
• Corporate organizational costs under Section 248
• Partnership organizational costs under Section 709
• Certain research or experimental expenditures under rules that have changed repeatedly
• Lease acquisition, software, bond premium, and other costs governed by separate provisions

Some costs are currently deductible, some must be capitalized without immediate recovery, and some use depreciation rather than amortization. The label "intangible" is not enough to choose a period.

Section 197 intangibles

Section 197 commonly covers qualifying intangibles acquired as part of purchasing a trade or business. Examples may include goodwill, going-concern value, workforce in place, business books and records, customer- and supplier-based intangibles, certain licenses or permits, covenants not to compete, franchises, trademarks, and trade names.

Qualifying basis is generally amortized ratably over 15 years, beginning with the month the intangible is acquired and the trade or business or income-producing activity begins using it. Self-created assets, separately acquired software, interests in entities, financial interests, and other exclusions can follow different rules. Anti-churning and related-party rules can also prevent Section 197 treatment.

A Section 197 amortization example

Suppose Coastal Design LLC buys another operating design business and properly allocates $90,000 of the purchase price to an acquired customer list that qualifies as a Section 197 intangible. It acquires and begins using the customer list in July.

The deduction is based on the statutory period, not management's estimate that the list will remain valuable for three years or twenty years. Purchase-price allocation and the acquisition agreement are essential support.

Start-up and organizational costs

Eligible start-up and organizational costs can have special rules allowing a limited current deduction, reduced when total costs exceed a statutory threshold, with the remainder amortized over 180 months. The rules and elections differ by cost type and entity.

Costs incurred before an active business begins should not automatically be posted as ordinary advertising, legal, travel, or professional-fee deductions. The business start date, nature of the activity, whether an acquisition occurred, and entity formation documents determine treatment. Costs that would not have been deductible if the business were active generally do not become deductible merely because they were paid during start-up.

Amortization versus loan principal and interest

A loan amortization table tracks each payment. The interest portion may be deductible if the debt and use of proceeds meet the applicable rules; the principal portion generally reduces the liability and is not an expense. Asset amortization does not follow the loan balance.

If a business borrows $90,000 to acquire a customer list, it may have both a loan-amortization schedule and a tax-amortization schedule. They are separate. Paying the loan faster does not accelerate Section 197 amortization, and financing the purchase does not prevent basis if the buyer is liable for the debt and other requirements are met.

Reporting amortization

Tax amortization beginning during the year is generally reported in Part VI of Form 4562 and flows to the return or schedule for the activity. A supporting schedule should identify the cost, acquisition date, amortization code or provision, period, prior deductions, current deduction, and remaining basis.

Books may use a different useful life or recognize impairment under the applicable accounting framework. Book amortization, federal tax amortization, and California tax amortization should be tracked separately when they differ.

Dispositions and the Section 197 loss rule

Selling an amortizable intangible requires calculating amount realized, adjusted basis, and the applicable character rules. A special Section 197 rule can defer recognition of a loss when one Section 197 intangible from an acquisition is disposed of while another from the same acquisition is retained. The unrecognized loss generally increases the basis of retained Section 197 intangibles.

This prevents taxpayers from selectively recognizing a loss on one component of acquired goodwill or going-concern value while continuing to hold related components. A fixed-asset schedule should preserve the acquisition grouping, not merely list each intangible independently.

Federal and California treatment

California often follows federal amortization concepts but does not conform to every federal change. California start-up, organizational, research, software, and other intangible-cost treatment can differ depending on the year and provision. California Form FTB 3885A or the applicable business-entity schedule may report depreciation and amortization adjustments.

Separate federal and California basis must be maintained whenever the deduction timing differs. A difference not tracked in the first year can cause incorrect deductions and gain or loss for many later years.

Common mistakes

• Calling every intangible a 15-year Section 197 asset
• Starting amortization on the payment date rather than the applicable acquisition or business-start date
• Omitting purchase-price allocation in a business acquisition
• Deducting all pre-opening costs as current expenses
• Confusing loan amortization with asset amortization
• Failing to file Form 4562 when amortization begins
• Continuing amortization after the asset is disposed of
• Claiming a Section 197 loss without considering retained intangibles
• Copying federal amounts into California without checking conformity

Records to keep

Retain purchase agreements, appraisals and allocation workpapers, invoices, legal and formation documents, proof of the active-business date, loan documents, prior Forms 4562, book and tax amortization schedules, federal and California returns, elections, related-party information, and disposition documents.
