US tax deductibility of environmental settlements (IRC 162(f))
- The record does not name which of my species, waters, soils or forests were harmed.
US tax law denies a deduction for amounts paid to a government for violating a law, but allows one for amounts identified in the settlement as restitution, remediation or compliance. A 2005 GAO review found that agencies did not negotiate the point and that responding companies deducted all or part of the payment in 20 of 34 settlements.
As reported by GAO-05-747 (2005): 34 settlements with company responses, out of 160 large settlements reviewed at four agencies.
Status As of October 2026: section 162(f) as amended in 2017 and the January 2021 regulations remain the rule described; actual deduction is documented only for the settlements named above.
- Companies that deducted all or part of a settlement (20 of 34 responding in the GAO sample) — Reduced taxable income US Government Accountability Office
- PG&E — Calculated a saving of about $468 million on its CPUC settlement
- The US public budget — Tax revenue foregone where deduction is taken; the sources reviewed that at a 21% rate $21 of each $100 deducted comes from the public budget
What happened
Section 162(a) of the US Internal Revenue Code allows a deduction for the "ordinary and necessary expenses" of a trade or business. Section 162(f) provides that amounts paid to a government for violating a law are not deductible. The exception is for amounts identified in the court order or settlement as restitution, including "remediation of property", or as compliance costs.
The 2017 tax law changed section 162(f) to its current form: a payment to a government is not deductible, but an amount identified in the order or settlement as restitution, remediation or compliance, and documented as spent for that purpose, can be deducted. The reporting threshold rose from $600 to $50,000. Final regulations issued on 12 January 2021 widened the meaning of remediation for environmental cases: payments to protect or restore soil, air or water, to restore forest or to provide habitat, that are linked to the harm, can qualify even where the harm cannot be fully remedied.
The label is set when the settlement is written. A 2005 review by the US Government Accountability Office (GAO-05-747, 15 September 2005) covered 160 large settlements reached in 2001–2002 at four federal agencies, with a combined value above $9 billion. None of the four agencies negotiated the tax deductibility of the payment. Of the 34 settlements for which companies answered the survey, companies had deducted all or part of the payment in 20, and deduction was more frequent where the payment was not called a penalty.
Two company cases are on record. Pacific Gas and Electric (PG&E) said its roughly $1.8 billion settlement with the California Public Utilities Commission over the 2017–2018 wildfires was "technically not a penalty" and calculated that deducting it would save about $468 million; the same agreement contained a commitment not to pass the cost on to customers (January 2020). 3M recorded a pre-tax charge of $10.3 billion in the second quarter of 2023 for its PFAS settlement with US public water suppliers; that figure is the present value, at 5.2%, of a nominal $12.5 billion payable from 2024 to 2036, and it reduced earnings per share by $14.19. The company's total tax line for that quarter was a $2.184 billion benefit; the sources reviewed does not show how much of it belongs to this settlement.
An earlier tax treatment is recorded for the 1989 Exxon Valdez spill: under a 1991 Alaska Department of Revenue position, civil and compensatory payments were deductible and fines were not. A secondary source (the Congressional Research Service as cited by Wood, 2010) put the after-tax cost of the $1.1 billion government settlement at "$524 million".

Record
- None on record How much of the $2.184 billion total tax benefit in 3M's second quarter of 2023 belongs to the PFAS settlement: the sources reviewed reports that the figure is not broken out.
- Unclear Whether the $1.2 billion tax benefit from Fire Victim Trust share sales recorded in PG&E's 2023 annual report is as stated: reported, but the relevant section of the report could be read only in part.
- Unclear Whether and how much of BP's Deepwater Horizon package was deducted: an estimate of about $15.3 billion of $20.8 billion deductible is noted in earlier entries, with no source given here.
Did the harm stop?
The record shows a tax rule that remains in force and a 2021 regulation that widened the remediation category; it shows no measure of whether payments reached the damaged environment.
Who paid?
The record reports that a deductible payment of $100 by a company taxed at 21% costs the public budget $21 of it; actual deductions in specific settlements are mostly not established in the record.
