Goodwill Impairment: What It Is and When a Small Buyer Tests for It

Goodwill impairment is the write-down a buyer books when the goodwill from an acquisition is worth less than the number carried on the balance sheet. It is an accounting entry, not a payment, and no cash leaves the company when it is recorded. That is exactly why owners ignore it, and exactly why it can arrive as a surprise, usually from a lender or an auditor rather than from the books.

The firm written up here is System Six, a Seattle bookkeeping and fractional CFO firm whose live profile says it helps organizations modernizing a finance function after an acquisition. It is a vetted Sam's List member and a paying member of our featured program; payment does not buy the language we use or its reviews. This is a general explainer, and your CPA decides how it applies to your company.

Goodwill vs Other Intangible Assets on a Small Buyer's Balance Sheet

When you buy a business, the price is spread across what you got. Cash, receivables, inventory, equipment and other identifiable assets are valued, liabilities are subtracted, and identifiable intangibles such as customer lists or a trade name are valued separately. Whatever price is left over is recorded as goodwill.

That is why goodwill vs other intangible assets matters. A customer list or a brand can be named, valued and assigned a life. Goodwill is the remainder: reputation, workforce, location and expected future earnings that cannot be separated and sold on their own. The split depends on a purchase price allocation, and the allocation you use for the books may differ from the one on your tax filings.

The limitation: goodwill is only as solid as the allocation behind it. A rushed allocation at closing can leave a large goodwill number that is hard to defend later.

What Goodwill Impairment Means

Impairment means the carrying amount of goodwill is more than it is worth. If the business you bought is earning much less than you expected, or a major customer leaves, the future earnings that justified the goodwill may no longer be there. The accounting answer is to write the goodwill down to what it is worth and record the difference as a loss in that period.

The write-down does not come back. If the business recovers, the books generally do not restore the goodwill. That one-way feature is why the timing of the test matters.

The limitation: an impairment is a signal about expected earnings, not a cause. The business is no more or less profitable the day after the entry. What changes is what the balance sheet says, and who reads it.

The Private Company Goodwill Amortization Election

Here is the part many small buyers do not know. Under U.S. GAAP, a private company may elect an alternative to the standard approach. The standard approach tests goodwill for impairment but does not amortize it. The private company goodwill amortization election lets a company that qualifies amortize goodwill in a straight line over ten years or less, and test for impairment only when something suggests it may be impaired.

For a small buyer, the election can cut cost and effort, because the testing is triggered by events rather than done on a schedule. The tradeoff is a steady amortization expense that lowers reported profit every period. The election is made for the company as a whole and, once made, is generally kept.

The limitation: the election applies to companies reporting under U.S. GAAP. Many small businesses keep books on a tax or cash basis and never report under GAAP. Whether you need to follow it at all depends on who reads your statements, and your CPA should confirm which framework applies.

When a Triggering Event Calls for a Goodwill Impairment Test

A triggering event is a change that makes it more likely than not that goodwill has lost value. Examples include the loss of a large customer, a sharp fall in revenue or margins, the departure of a key person who held relationships, a legal dispute, a significant rise in costs or a decision to wind down part of the business. A weak quarter does not automatically count. What matters is whether it changes your view of the earnings that justified the price.

Under the private company alternative, you look for these events at a reporting date and test only if one has occurred. Keep a short written note each reporting period that says what you considered and why you did or did not test. Auditors and lenders like to see that the question was asked.

The limitation: judgment is involved, and reasonable people can disagree on whether an event is large enough. When it is close, a CPA's view, documented, is better than silence.

What a Goodwill Write-Down Can and Cannot Change

A write-down lowers reported profit and equity in the period it is recorded. It does not reduce cash, and it does not by itself change your tax bill. Goodwill acquired in a taxable asset purchase is generally amortized for tax over 15 years under Internal Revenue Code section 197, on its own schedule, regardless of what the books show.

The practical risk is a loan agreement. Some covenants are measured on equity, net worth or earnings, and a write-down can move those numbers. Many agreements define earnings so that non-cash charges are added back, but not all do. Read the definition before the entry, not after.

The limitation: tax and book goodwill can diverge for years, and the difference needs tracking. A write-down on the books is not a tax deduction.

Where System Six Fits After a Purchase

System Six is based in Seattle, was founded in 2009 and has 41 employees. It serves businesses nationwide with revenue between $1 million and $10 million, and its profile says the firm was acquired by a searcher in 2021. It lists Non-Profit Organizations, Professional Service Firms and Real Estate Investors as specialties.

For a buyer, the relevant piece is the finance function that has to exist after close: monthly books, a clear record of what was paid and how the price was allocated, and a calendar for the questions this article raises. That is bookkeeping and fractional CFO work.

System Six does not yet have enough verified reviews on Sam's List for a count to be meaningful, so we do not cite one. Ask the firm for references from owners who bought a business.

The limitation, plainly: the profile does not list accounting-standards elections, impairment testing, valuation or tax preparation as services, and a bookkeeping firm is not a substitute for a CPA on those. The $1 million revenue minimum on the profile also means a smaller business may fall outside what the firm takes on.

Frequently Asked Questions

What is goodwill impairment in simple terms?

It is a write-down of goodwill from an acquisition when the goodwill is worth less than the number on the books. The loss is recorded in the period it is found, no cash moves, and the write-down generally is not reversed if the business recovers. A CPA decides when one is needed.

Do small private companies have to test goodwill every year?

Not necessarily. Under U.S. GAAP, a private company can elect to amortize goodwill over ten years or less and test only when a triggering event occurs. Companies that do not report under GAAP may not test at all. Confirm which applies to you before the first reporting date.

Is goodwill impairment tax deductible?

Generally no. A book write-down does not by itself create a tax deduction. Goodwill from a taxable asset purchase is typically amortized for tax over 15 years, separately from the books. Ask your CPA how the two are tracked.

Can a goodwill write-down trigger a loan covenant problem?

It can, if the covenant is measured on equity or earnings and the agreement does not add back non-cash charges. Read the definitions in the loan agreement and ask the lender before you record a large entry.

If you bought a business this year, one request is worth making before your next close: ask your CPA to put the purchase price allocation and the goodwill policy in a single page. You can browse fractional CFOs on Sam's List, including the firm above, and your CPA decides what the accounting answer is.
