Goodwill Accounting After an Acquisition: What CFOs Need to Know

After an acquisition closes, goodwill accounting picks up where the deal team left off. Under U.S. GAAP, goodwill is the excess of the purchase price over the fair value of the identifiable net assets acquired. It sits on the balance sheet indefinitely but must be tested for impairment at least annually, unless the company elects the private company alternative to amortize it instead. The rules differ in important ways between public companies, private companies, and the tax return, and getting them wrong creates financial statement errors that auditors and lenders notice.

How Goodwill Is Created in a Business Combination

Every acquisition accounted for as a business combination under ASC 805 follows the acquisition method. The acquirer:

1. Identifies and measures all identifiable assets acquired and liabilities assumed at their fair values on the acquisition date.
2. Recognizes any separately identifiable intangible assets apart from goodwill.
3. Calculates goodwill as the residual: purchase consideration minus the fair value of net identifiable assets.

Goodwill represents what the buyer paid for things that cannot be individually identified and measured. That includes assembled workforce, synergies, going-concern value, and market position that would not qualify as a separable intangible.

Separating Identifiable Intangibles from Goodwill

One of the most consequential steps in purchase price allocation is pulling identifiable intangible assets out of goodwill. Under ASC 805, an intangible is identifiable if it meets either of two criteria:

• Separability criterion. The asset can be separated from the acquiree and sold, transferred, licensed, rented, or exchanged, either alone or together with a related asset or liability.
• Contractual-legal criterion. The asset arises from contractual or other legal rights, regardless of whether it can be separated.

Common intangibles recognized in a business combination include customer relationships, trade names and trademarks, developed technology and software, non-compete agreements, favorable lease contracts, and order backlog. Each is measured at fair value at the acquisition date using income, market, or cost approaches.

Getting this step right matters. Overstuffing goodwill by failing to recognize separable intangibles understates amortization expense in future periods. It also draws scrutiny from auditors, since it inflates a balance sheet figure that cannot be amortized under the standard public-company model.

Goodwill Accounting After the Deal: The GAAP Framework

After the acquisition date, goodwill is not amortized under the standard model. Instead, it is tested for impairment. The rules are codified in ASC 350-20.

Annual Impairment Testing for Public Companies

Public companies must test goodwill for impairment at least once a year, at the same point during the fiscal year each year. Testing is performed at the reporting unit level, which is an operating segment or a component of an operating segment.

The process has two stages:

Step 0 (Qualitative Assessment). The entity assesses whether it is more likely than not that the reporting unit’s fair value is below its carrying amount. If not, no further testing is required. Relevant factors include macroeconomic conditions, industry trends, cost increases, declining financial performance, and changes in equity multiples or market capitalization. In periods of higher discount rates or revised cash flow forecasts, the qualitative assessment often fails to provide a clean pass, and companies proceed to the quantitative test.

Step 1 (Quantitative Test). If Step 0 indicates potential impairment, the entity compares the reporting unit’s fair value to its carrying amount. If fair value is lower, an impairment loss is recognized for the difference, limited to the total amount of goodwill allocated to that reporting unit. Under current rules, the loss cannot exceed the goodwill allocated to the unit, and there is no separate write-down of other assets in the test.

Triggering events outside the annual test cycle can require interim testing. Examples include a significant adverse change in business climate, a major customer loss, or a sustained drop in a public company’s market capitalization below book value.

In 2026, the FASB added a project to its technical agenda to make targeted improvements to goodwill impairment testing. The Board’s tentative decisions focus on two changes: eliminating the requirement to test goodwill for impairment on an annual basis, and testing goodwill at the operating segment level rather than the reporting unit level. No final standard has been issued, so annual impairment testing at the reporting unit level remains required for public companies today.

Identifiable Intangible Assets: Subsequent Accounting

Unlike goodwill, separately recognized intangible assets with finite useful lives are amortized over their estimated economic lives. The amortization method should reflect the pattern in which economic benefits are consumed. Most entities use straight-line. Intangibles with indefinite useful lives (many trade names, for example) are not amortized but are tested for impairment annually, similar to goodwill.

The useful life assessment must be revisited each reporting period. If circumstances change and a finite-lived intangible’s remaining useful life shortens materially, the carrying amount is amortized over the revised period.

The Private Company Election: Goodwill Amortization

For privately held companies, FASB’s Private Company Council created a practical alternative. Under this election, a private company or not-for-profit can amortize goodwill on a straight-line basis over 10 years, or less if the company can demonstrate a shorter life is more appropriate. Companies commonly elect the 10-year period without justification.

Two separate elections exist, and they can be adopted independently:

1. ASU 2014-02 Amortization Alternative. Amortize goodwill rather than test it annually. After adoption, the company still tests for impairment when a triggering event occurs, but the impairment test is a single-step test comparing the fair value of the entity (or reporting unit) to its carrying amount.
2. ASU 2021-03 Triggering Event Alternative. Rather than monitoring for triggering events throughout the year, the company evaluates whether a triggering event occurred, and whether goodwill may be impaired, only at the end of each reporting period. This eliminates the burden of mid-period monitoring.

These elections are available for acquisitions completed before or after the election is made. For goodwill already on the balance sheet when the election is adopted, the company begins amortizing from the adoption date over the lesser of 10 years or the remaining original useful life. The elections are irrevocable once made.

Why it matters for mid-market companies: amortizing goodwill reduces reported earnings each period, which can affect EBITDA metrics in debt covenants and earnouts. Before making the election, your advisory team should assess the impact on existing covenants, lender ratios, and management compensation tied to earnings.

Tax Treatment of Goodwill and Intangibles

Tax law follows a completely different model than GAAP, and the difference creates timing differences that affect deferred tax accounting.

Section 197: 15-Year Straight-Line Amortization

Under Section 197 of the Internal Revenue Code, goodwill and most other intangibles acquired in a taxable asset purchase are amortized ratably over 15 years beginning with the month of acquisition. The 15-year period applies regardless of the asset’s actual economic life or the GAAP useful life assigned to it.

Section 197 intangibles include goodwill, going concern value, workforce in place, customer lists, patents, copyrights, franchises, trademarks, trade names, and licenses. The deduction is available only in an asset acquisition, or a deal structured to be treated as one (such as a Section 338(h)(10) or Section 336(e) election in a stock deal).

In a plain stock acquisition, the buyer takes over the target’s historical tax basis and cannot amortize goodwill. This is a central reason why buyers prefer asset deals and why deal structure negotiation matters so much.

GAAP vs. Tax Timing Differences

A company that amortizes goodwill under the private company election will deduct it faster on the GAAP books (over 10 years or less) than on the tax return (over 15 years). A public company that carries goodwill at cost without amortization will have a permanent GAAP-to-tax difference. Both scenarios require careful deferred tax asset and liability analysis in the acquisition’s opening balance sheet and in every subsequent period.

Disclosure Requirements

Audited financial statements require robust disclosures about goodwill and intangibles. Under ASC 350 and ASC 805, required disclosures include:

• A reconciliation of the beginning and ending carrying amount of goodwill, showing additions from acquisitions, impairment losses, and any disposals.
• The gross amount of goodwill and accumulated impairment losses.
• Aggregate amortization expense for finite-lived intangibles and an estimate of future amortization for the next five years.
• The total amount of goodwill expected to be deductible for tax purposes.
• Description and carrying amount of significant intangible assets by major class.

If the private company amortization election is in use, disclosures include the aggregate amount of goodwill amortized each period and the remaining carrying amount.

Common Pitfalls to Avoid

Several recurring mistakes show up in post-acquisition accounting:

Undervaluing intangibles in the PPA. Assigning too little fair value to identifiable intangibles inflates goodwill. This error is difficult to correct after the measurement period closes (generally one year after the acquisition date).

Missing the measurement period window. Provisional fair value estimates must be finalized within 12 months of the acquisition. After that, adjustments are recorded prospectively, not retroactively.

Ignoring triggering events. Companies that skip interim impairment assessments when business conditions deteriorate expose themselves to material misstatements. Auditors look closely at triggering event documentation.

Assuming the private company election is always advantageous. Amortization reduces net income and may violate debt covenants based on EBITDA or net asset ratios. Always model the covenant impact before electing.

Misaligning tax and book structure. A deal closed as a stock purchase without a 338 election leaves the buyer with no Section 197 deductions. This can be worth tens of millions of dollars in present value on a mid-market deal.

Frequently Asked Questions

How is goodwill accounted for after an acquisition?

Under U.S. GAAP, goodwill is recognized at the excess of the acquisition purchase price over the fair value of identifiable net assets. Public companies carry goodwill at cost and test it for impairment at least annually under ASC 350-20. Private companies may elect to amortize goodwill over 10 years or fewer using the Private Company Council alternative, reducing the impairment testing burden significantly.

What is the private company election for goodwill impairment?

The private company election, established through ASU 2014-02, allows privately held companies and not-for-profits to amortize goodwill on a straight-line basis over a period not to exceed 10 years, rather than testing annually for impairment. A separate election under ASU 2021-03 allows these entities to evaluate triggering events only at the end of the reporting period rather than throughout the year. Both elections are irrevocable once adopted.

How long is goodwill amortized for tax purposes?

For federal income tax purposes, goodwill acquired in a taxable asset purchase is amortized ratably over 15 years under Section 197 of the IRC, using the straight-line method starting from the month of acquisition. This applies regardless of the asset’s actual useful life. In a stock acquisition without a Section 338(h)(10) or 336(e) election, the buyer inherits the seller’s historical tax basis and cannot deduct goodwill amortization.

What intangible assets must be separately recognized in a business combination?

ASC 805 requires the acquirer to separately recognize any intangible asset that meets either the separability criterion (it can be sold, licensed, or transferred separately) or the contractual-legal criterion (it arises from legal rights). Common separately recognized intangibles include customer relationships, trade names, developed technology, non-compete agreements, and favorable contracts. Intangibles that do not meet these criteria remain in goodwill.

What triggers an interim goodwill impairment test?

Under ASC 350-20, an entity must test goodwill for impairment between annual tests when a triggering event occurs. Common triggering events include a significant decline in the reporting unit’s actual or projected revenue, a sustained drop in stock price below book value, loss of a major customer, regulatory actions, or deteriorating macroeconomic conditions affecting the unit’s industry. Companies that have adopted ASU 2021-03 evaluate triggering events at each period end rather than on an ongoing basis throughout the year.

Does FASB plan to change goodwill accounting rules?

In 2026, the FASB added a project on targeted improvements to goodwill impairment testing to its technical agenda. Its tentative decisions would eliminate the requirement to test goodwill annually and would move testing from the reporting unit level to the operating segment level. The project remains in progress and no final standard has been issued, so current rules still apply. Companies should monitor FASB’s technical agenda for developments.
