No. A goodwill impairment write-down is not tax deductible. The only tax deduction available for purchased goodwill is the 15-year straight-line amortization required by Section 197 of the Internal Revenue Code, and that deduction runs on its own schedule no matter what the goodwill looks like on your balance sheet. When you record an impairment charge, book value drops and the income statement takes a non-cash hit, but the tax deduction does not change. Not that year, not the next, not ever, based on the write-down alone.
What You Can Deduct: Section 197 Amortization
When a company acquires a business and pays more than the fair market value of the identifiable assets minus liabilities, the excess is recorded as goodwill. For tax purposes, that purchased goodwill falls under Section 197, which requires the buyer to deduct the cost in equal monthly installments over exactly 15 years, starting the month of the acquisition.1Office of the Law Revision Counsel. 26 USC 197 Amortization of Goodwill and Certain Other Intangibles There is no option to shorten the period, no option to front-load the deduction, and no option to accelerate what remains when the asset loses value. Every month gets the same slice.
Section 197 also shuts the door on any other method. The statute says that except for the 15-year amortization it provides, “no depreciation or amortization deduction shall be allowable” for a Section 197 intangible.2Office of the Law Revision Counsel. 26 US Code 197 – Amortization of Goodwill and Certain Other Intangibles That language is what prevents an impairment charge from becoming a tax deduction. The scheduled amortization keeps running even after the goodwill has been written down to zero on the financial statements.
Why the Impairment Charge Itself Doesn’t Deduct
U.S. tax law runs on the realization principle: you generally cannot claim a loss until a transaction fixes it. Selling an asset, abandoning it, or having it become genuinely worthless counts. Deciding an asset is worth less on paper does not. A goodwill impairment is exactly that kind of paper revaluation. Book value goes down and the income statement absorbs the charge, but no transaction has occurred and no property has changed hands.
The practical effect is that the tax basis and the book basis of goodwill can diverge sharply after an impairment. Say a company acquired $100 million of goodwill five years ago. The tax basis has been reduced by five years of Section 197 amortization to roughly $66.7 million. If a $40 million impairment charge brings book value down to $26.7 million, the tax basis is still $66.7 million. That $40 million gap is a permanent difference for tax reporting. The write-down will never produce a tax deduction on its own.
The divergence matters when the business unit is eventually sold. Gain or loss on disposition is measured against tax basis, not book basis. A company that recorded a large impairment and then sells the unit at roughly book value may actually report a tax loss, because the tax basis remained higher than the sale price. The reverse also happens: a sale above book value but below tax basis still generates a tax loss. Companies that ignore the basis divergence can be caught off guard at disposition.
When a Goodwill Loss Does Become Deductible
A tax loss on goodwill becomes available only when you dispose of or abandon the entire trade or business that was acquired, with no retained Section 197 intangibles from that acquisition. At that point, the remaining unamortized tax basis produces a deductible loss under Section 165, which allows a deduction for any loss sustained during the taxable year that is not compensated by insurance or other recovery.3Office of the Law Revision Counsel. 26 USC 165 Losses
Partial dispositions run into a barrier. Treasury regulations contain a loss disallowance rule: no loss is recognized on the disposition of a Section 197 intangible if the taxpayer retains any other Section 197 intangibles acquired in the same transaction. In a typical acquisition, the buyer picks up multiple Section 197 intangibles at once: goodwill, customer lists, trade names, non-compete agreements. If the buyer later sells or abandons just one of them at a loss, the loss is disallowed, and the unrecovered basis gets reallocated to the remaining intangibles from the same deal. Those retained intangibles continue to amortize on the original 15-year schedule, with their bases increased to absorb the disallowed loss.4eCFR. 26 CFR 1.197-2 – Amortization of Goodwill and Certain Other Intangibles
This is where most companies hoping to accelerate a goodwill deduction hit the wall. You cannot carve out the goodwill from an acquisition, write it off, and keep everything else. The regulations treat it as an all-or-nothing proposition tied to the entire bundle of intangibles from the same deal.
Abandonment and worthlessness get a specific carve-out. The regulations treat abandonment or worthlessness of a Section 197 intangible as a disposition, but the abandoned or worthless intangible is disregarded when evaluating whether the taxpayer retains other intangibles from the same transaction.4eCFR. 26 CFR 1.197-2 – Amortization of Goodwill and Certain Other Intangibles So if the entire acquired business closes and all of the associated intangibles become worthless simultaneously, the loss disallowance rule stops blocking the deduction.
Proving abandonment or worthlessness is a factual question that requires solid documentation. You need to establish ownership of the asset, intent to abandon it, and an affirmative act of abandonment. That means records of the decision-making process: board resolutions, correspondence with advisors, the date operations ceased, and evidence that the business was not transferred to another party. Vague assertions that the goodwill “has no value” will not satisfy the IRS if the underlying business continues operating.
How the Non-Deductible Charge Gets Reported
Even though the impairment produces no deduction, it still has to show up on the return, cleanly identified as a book-only adjustment. Corporations with total assets of $10 million or more file Schedule M-3 with Form 1120 to reconcile financial statement income with taxable income. Goodwill amortization and impairment are reported on Part III, Line 26. The write-down amount goes in the financial statement column and gets backed out as a permanent difference, producing zero impact in the taxable income column. The IRS instructions provide a direct example: a $5,000 goodwill impairment charge is reported as a permanent difference of negative $5,000, with $0 flowing to taxable income.5Internal Revenue Service. Instructions for Schedule M-3 (Form 1120)
The annual Section 197 amortization deduction runs on its own track and is reported on Form 4562, which covers both depreciation and amortization and is attached to the entity’s income tax return.6Internal Revenue Service. Form 4562 – Depreciation and Amortization The form requires the date amortization began, the amortizable amount, the Code section authorizing the deduction, the amortization period, and the current-year deduction. That deduction continues at the same monthly rate after any impairment, using the original tax basis and the original 15-year schedule.
Keep the impairment testing documentation too. It supports the Schedule M-3 reconciliation and shows an examiner that the company treated the write-down as a non-deductible book adjustment rather than slipping it into a tax deduction elsewhere on the return.
