The de minimis rule is a legal doctrine that allows courts, regulators, and tax authorities to disregard violations or amounts so trivial that enforcing them would cost more than the harm is worth. The name comes from a Latin phrase meaning “the law does not concern itself with trifles.” The idea sounds simple, but it works very differently depending on where it shows up: a few unpaid minutes at the end of a shift, a holiday turkey from your employer, a $20 discount on a bond, a two-second music sample, a technical safety-standard shortfall, or a single grape taken at a grocery store can all be treated as beneath the law’s attention, and each has its own test for whether it qualifies.
What the Doctrine Actually Does
At its core, the rule gives decision-makers permission to look past technically real but practically meaningless infractions. The judgment always circles back to the same question: is the harm or amount significant enough to justify the cost of enforcement?
This is not a license to break small rules. The doctrine protects against enforcement of trivial matters, not small-but-real ones, and its reach varies dramatically by area of law. Some contexts spell out specific thresholds in regulation. Others leave the call to judges, who often decline to make it. In civil trespass, for instance, courts have largely rejected the defense outright.
Unpaid Minutes Under the Fair Labor Standards Act
Under the FLSA, the de minimis rule covers the handful of extra minutes an employee might work beyond scheduled hours. The federal regulation at 29 CFR § 785.47 says that “insubstantial or insignificant periods of time beyond the scheduled working hours, which cannot as a practical administrative matter be precisely recorded for payroll purposes, may be disregarded.”1eCFR. 29 CFR 785.47 The regulation talks in terms of “a few seconds or minutes,” and the exception only applies when the practical realities of timekeeping justify ignoring the time.
There’s no bright-line cutoff at ten minutes or any other number. Courts weigh three things: how long the extra work takes, how often it happens, and whether the employer could realistically track it. A one-off incident of shutting down equipment for two minutes after clocking out is the textbook example.2U.S. Department of Labor. FLSA Hours Worked Advisor
Regularity breaks the defense. If a worker spends even two or three minutes on a task every shift, that time becomes predictable enough to log, and the employer has to pay for it. The Department of Labor is explicit: “An employer may not arbitrarily fail to count as hours worked any part, however small, of the employee’s fixed or regular working time or practically ascertainable period of time he is regularly required to spend on duties assigned to him.”1eCFR. 29 CFR 785.47 Employers who ignore recurring off-the-clock work face back pay and potential liquidated damages.
Tax Code Applications
The federal tax code uses the de minimis concept in several places, each with its own threshold. The common thread is administrative practicality.
Fringe Benefits
Under 26 U.S.C. § 132(e), a “de minimis fringe” is any employer-provided property or service whose value, “after taking into account the frequency with which similar fringes are provided,” is “so small as to make accounting for it unreasonable or administratively impracticable.”3Office of the Law Revision Counsel. 26 USC 132 – Certain Fringe Benefits These benefits are excluded from gross income and owe no federal income or payroll taxes. Common examples include occasional personal use of a company copier, a holiday turkey, and coffee and snacks in the break room. The IRS stresses that qualifying benefits must be “occasional or unusual in frequency.”4Internal Revenue Service. De Minimis Fringe Benefits
One trap catches employers constantly: cash and cash equivalents like gift cards are almost never de minimis, regardless of amount. A $15 coffee-shop gift card is taxable wages because it has a readily determinable cash value. The only carved-out exception is occasional meal money or transit fare for genuinely unusual overtime, and even then the money can’t be calculated based on hours worked.4Internal Revenue Service.

Safe Harbor for Small Business Purchases
Businesses face a recurring question about small purchases: capitalize and depreciate, or expense now? The IRS de minimis safe harbor settles it. A business with an applicable financial statement (an audited statement, for example) can expense items costing up to $5,000 per invoice. Without one, the threshold is $2,500 per invoice. You elect the safe harbor annually by attaching a statement to your tax return. It doesn’t apply to inventory or land, and because it’s an annual election rather than an accounting method change, there’s no Form 3115.5Internal Revenue Service. Tangible Property Final Regulations
Original Issue Discount on Bonds
When you buy a bond issued below face value, the difference is original issue discount, and you normally owe tax on it each year. If the discount is tiny, the de minimis rule lets you treat it as zero. The threshold is one-quarter of one percent (0.25%) of the bond’s face value, multiplied by the number of full years to maturity.6Office of the Law Revision Counsel. 26 USC 1273 – Determination of Amount of Original Issue Discount On a 10-year, $1,000-face bond, that’s $25. Buy it at $980 and the $20 discount is below the threshold and treated as zero; buy it at $970 and the full $30 is reportable OID.7Internal Revenue Service.

The $800 Customs Threshold and What Changed in 2025
For years, the most consumer-visible de minimis rule governed low-value imports. Under 19 U.S.C. § 1321, goods shipped to the United States valued at $800 or less per person per day could enter duty-free and tax-free with minimal paperwork.8Office of the Law Revision Counsel. 19 USC 1321 – Administrative Exemptions That exemption powered the direct-to-consumer model of international e-commerce platforms.
It no longer works that way. In April 2025, an executive order eliminated the exemption for products from China and Hong Kong effective May 2, 2025, subjecting those shipments to full duties including Section 301 tariffs. Postal packages from China valued under $800 faced either a 30% ad valorem duty or a flat per-item charge.9The White House. Further Amendment to Duties Addressing the Synthetic Opioid Supply Chain in the People’s Republic of China as Applied to Low-Value Imports Then in July 2025, a broader executive action suspended duty-free de minimis treatment for shipments from all countries, regardless of value, origin, or method of entry.10The White House. Suspending Duty-Free De Minimis Treatment for All Countries The $800 threshold still sits in the statute, but the suspension means it currently provides no practical benefit. Anyone ordering goods from overseas should expect to pay duties and taxes on the full shipment value.
Copyright and Music Sampling
In copyright law, de minimis is a defense against infringement where the amount of copyrighted material used is so small that no reasonable audience would recognize it. This is separate from fair use. Fair use asks whether the copying was justified; de minimis asks whether the copying was significant enough to count as infringement at all.
For most types of works, including books, photographs, films, and musical compositions, the defense remains available. Briefly and unrecognizably incorporate a fragment of someone else’s work, and a court may find the use too trivial to be actionable.
Sound recordings are the exception, and the federal circuits are split. In 2005, the Sixth Circuit held in Bridgeport Music, Inc. v. Dimension Films that there is no de minimis threshold for sampling recorded music. The court’s instruction was blunt: “Get a license or do not sample.” Its reasoning was that sampling involves a physical taking of fixed sounds rather than borrowing a musical idea.11Harvard Cyber Law. Bridgeport Music, Inc. v. Dimension Films, 410 F.3d 792 (6th Cir. 2005) The Ninth Circuit rejected that reasoning in VMG Salsoul, LLC v. Ciccone (2016), holding that the de minimis exception does apply to sound recordings and calling the Sixth Circuit’s statutory interpretation a “logical fallacy.” The result is geographic. In Michigan, Ohio, Kentucky, and Tennessee, any unlicensed sample is potentially infringing regardless of length. In the Ninth Circuit (which includes California, home to much of the music industry), a truly trivial sample can still fall below the legal threshold. Other circuits have not weighed in definitively.
OSHA De Minimis Violations
OSHA classifies some workplace violations as de minimis when they involve a technical departure from a safety standard but have “no direct or immediate relationship to safety or health.”12Occupational Safety and Health Administration. 29 CFR 1903.14 – Citations; Notices of De Minimis Violations An example might be a guardrail a quarter-inch shorter than the specification in a context where the shortfall creates no actual danger.
The practical difference is significant. A de minimis violation produces a notice, not a citation, and carries no financial penalty. It doesn’t go on the employer’s violation record the way a serious, willful, or repeat citation would. OSHA still documents the condition and expects it to be corrected, but the agency is essentially saying fix this without punishing you for it.
Criminal Prosecutions
A de minimis defense also exists in criminal cases, though it comes up far less often than in regulatory or civil contexts. The Model Penal Code, which has shaped criminal statutes in a majority of states, lets a court dismiss a prosecution when the conduct fell within customary tolerance, caused harm too trivial to warrant conviction, or wasn’t the kind of thing the legislature meant to forbid.
In practice, the defense surfaces when someone is technically guilty but the circumstances make prosecution absurd. A shopper who eats a single grape while walking through a grocery store has committed theft on paper, and a court applying de minimis would dismiss the charge as beneath the dignity of a criminal proceeding. Not every jurisdiction recognizes the defense, and even where it exists, judges use it sparingly and typically have to file a written explanation when they do.
Civil Suits: Why Nominal Damages Aren’t the Same Thing
In civil litigation, the de minimis principle gets confused with nominal damages, and the distinction matters.
Some claims have a built-in significance threshold. Nuisance requires substantial harm before any liability attaches, so a faint odor that bothers nobody fails to clear the bar. The harm is too trivial for the law to recognize at all. That’s de minimis in operation.
Trespass works the opposite way. Courts have traditionally applied strict liability to trespass, meaning any unauthorized physical intrusion on someone’s land is actionable regardless of how brief or harmless.13Columbia Law School Scholarship Archive. Trespass, Nuisance, and the Costs of Determining Property Rights The remedy for a harmless trespass is nominal damages, often one dollar, which exist to vindicate the owner’s legal right rather than to compensate for a real loss. The claim itself was never dismissed as trivial. The law took the violation seriously and simply found the harm negligible.
Breach of contract follows the same logic. When one party breaches but the other suffers no measurable financial loss, courts may award nominal damages to acknowledge the breach without pretending there was anything to compensate. For anyone weighing a lawsuit over a minor breach, the practical point is that winning on the merits doesn’t guarantee meaningful recovery, and litigation costs will almost always dwarf a nominal award.
