To record amortization of goodwill, post a journal entry that debits Amortization Expense and credits Accumulated Amortization—Goodwill for the periodic amount, calculated as the goodwill balance from the acquisition divided by the useful life (ten years by default under the ASC 350-20 accounting alternative). Only private companies and nonprofit organizations can make this entry; public companies do not amortize goodwill under U.S. GAAP and instead test it for impairment.
Confirm You Can Amortize in the First Place
Public companies that file with the SEC treat goodwill as an indefinite-lived intangible asset and test it for impairment at least annually. No amortization entry gets posted.
Private companies and nonprofits can elect the accounting alternative in FASB ASU 2014-02, which permits straight-line amortization instead of routine annual impairment testing.1FASB. FASB ASU 2014-02 Intangibles Goodwill and Other Topic 350 The alternative lives in ASC 350-20 and covers goodwill from business combinations, acquisitions by nonprofits, and fresh-start reporting.2Deloitte Accounting Research Tool (DART). Chapter 3 Goodwill Accounting Alternatives for Private Companies and NFPs – 3.1 Overview Once elected, it applies to all existing goodwill and to any goodwill recognized later. It is not a per-acquisition choice.
Pull the Two Numbers You Need
Before posting anything, you need the goodwill balance and the useful life.
The goodwill balance comes from the closing balance sheet of the acquisition: total purchase price minus the fair value of identifiable assets acquired and liabilities assumed. Pay $3 million for a business with $2.2 million in net identifiable assets and goodwill is $800,000. Document that figure in your permanent acquisition file; every future amortization entry anchors to it.
The useful life defaults to ten years, and an entity that picks ten years does not have to justify the choice.3Deloitte Accounting Research Tool (DART). 3.3 Goodwill Amortization Alternative A shorter life is allowed if you can support it. ASC 350-20-35-63 requires straight-line amortization for each “amortizable unit of goodwill,” so each acquisition gets its own schedule.4FASB. FASB ASU 2021-03 Intangibles Goodwill and Other Topic 350
Calculate the Periodic Amount
Divide the goodwill balance by the number of periods in the useful life. Goodwill of $500,000 over ten years produces $50,000 per year, $12,500 per quarter, or $4,166.67 per month. Straight-line is the only permitted method under the alternative, so the amount does not change from period to period.
Mid-year closings need proration. A deal that closes in July on a calendar-year reporter produces six months of book amortization in the first year: $25,000 rather than $50,000 on the $500,000 example. The final year picks up the remaining six months. Most controllers set the schedule in the accounting software at acquisition so the software prorates automatically.
The Journal Entry
The periodic entry looks the same whether you post it monthly, quarterly, or annually. Using $500,000 of goodwill, a ten-year life, and monthly reporting:
- Debit Amortization Expense $4,166.67
- Credit Accumulated Amortization—Goodwill $4,166.67
The debit flows to the income statement and reduces net income for the period. No cash moves.
The credit side involves a choice. Crediting Accumulated Amortization—Goodwill (a contra-asset that offsets gross goodwill) is the standard approach and preserves visibility of both the original acquisition cost and the amount written off to date. Crediting the Goodwill account directly is also acceptable but hides the original basis. The contra-asset method aligns with the ASC 350-20 disclosure requirement to report gross carrying amounts and accumulated amortization separately.5Deloitte Accounting Research Tool (DART). 5.5 Presentation and Disclosure Requirements for Private Companies and NFPs
Set the entry to recur in your accounting software based on the schedule established at acquisition. Verify the cumulative total against the original goodwill balance during the annual close so nothing has drifted.
Record the Tax Amortization Separately
The book entry above is only half the picture. For federal tax purposes, Section 197 of the Internal Revenue Code requires goodwill to be amortized ratably over 180 months (fifteen years), starting in the month the intangible was acquired.6Office of the Law Revision Counsel. 26 USC 197 Amortization of Goodwill and Certain Other Intangibles
The tax calculation uses a full-month convention. A September 15 closing on the $500,000 example produces $2,777.78 per month ($500,000 ÷ 180). The first calendar year’s deduction covers September through December: $11,111.11.7Office of the Law Revision Counsel. 26 US Code 197 Amortization of Goodwill and Certain Other Intangibles Report the deduction on Form 4562, Part VI.8IRS.gov. Instructions for Form 4562 Depreciation and Amortization
Ten-year book life against fifteen-year tax life creates a temporary difference under ASC 740. In the early years, book amortization exceeds tax amortization, producing a deferred tax liability when goodwill is tax-deductible.9Deloitte Accounting Research Tool (DART). 11.3 Recognition and Measurement of Temporary Differences The mechanics get intricate, and most private companies work with their tax advisors to set up the deferred tax entries at acquisition rather than recalculating each quarter. The point for the closing process: the amortization entry alone is not complete without the corresponding deferred tax entry.
Impairment Uses a Different Entry
Electing to amortize does not eliminate impairment testing. It replaces the annual requirement with a triggering-event model: at each reporting date, assess whether a triggering event suggests goodwill might be impaired.1FASB. FASB ASU 2014-02 Intangibles Goodwill and Other Topic 350 Triggering events include a significant decline in financial performance, loss of key customers or contracts, industry downturns, or adverse regulatory changes. A qualitative screen comes first; a quantitative test follows only if the screen indicates probable impairment.
When impairment is confirmed, the entry is different from routine amortization. The charge equals the carrying amount in excess of fair value, capped at the goodwill balance, and the credit hits Goodwill directly rather than accumulated amortization:
- Debit Goodwill Impairment Loss
- Credit Goodwill
Impairment losses cannot be reversed in later periods and appear on the income statement separately from amortization expense.
Where the Entry Lands on the Statements
Amortization expense sits within continuing operations, generally as part of the depreciation and amortization line or as a separate operating expense line.5Deloitte Accounting Research Tool (DART). 5.5 Presentation and Disclosure Requirements for Private Companies and NFPs Goodwill related to a discontinued operation is reported within discontinued operations on a net-of-tax basis.
The balance sheet carries goodwill at net: original cost less accumulated amortization and any accumulated impairment. Under the contra-asset approach, the presentation looks like this:
- Goodwill (gross): $500,000
- Less: Accumulated Amortization: ($150,000)
- Goodwill (net): $350,000
At the end of the useful life, absent any impairment, the net balance reaches zero and the periodic entry stops.
The footnotes for each period presented must show gross carrying amount, accumulated amortization, accumulated impairment losses, aggregate amortization expense, and the weighted-average amortization period, along with the amount assigned to goodwill and the amortization period for each major acquisition during the period.5Deloitte Accounting Research Tool (DART). 5.5 Presentation and Disclosure Requirements for Private Companies and NFPs Disclose the use of the amortization alternative itself as a significant accounting policy.
