Definition
A gratuity is a voluntary payment made to another person as an expression of thanks or goodwill, not as compensation owed under any contract or legal obligation. The defining feature is voluntariness: a gratuity arises from the donor's free choice, not from duty.
The term carries distinct weight in several legal contexts:
1. Gifts and donative transfers. In general private law, a gratuity is a transfer made without consideration — the giver receives nothing in return. This distinguishes it from a contract, where mutual obligation is required.
2. Employment and service contexts. Tips and service charges paid to workers occupy contested ground. A genuine gratuity is discretionary; an automatic service charge added to a bill is generally not a gratuity in the legal sense, even if colloquially called one.
3. Public employment and government benefits. Payments made by a government or employer to an employee or veteran beyond what is contractually or statutorily required — sometimes called "bonus" or "bounty" — have been characterized as gratuities. This classification has constitutional and statutory consequences, particularly regarding the government's power to attach conditions or later modify such payments.
4. Bribery and ethics law. In criminal and ethics statutes, "gratuity" often refers to a payment made to a public official in connection with an official act — distinguished from a bribe in that a gratuity may be given after the act rather than as an inducement before it. Federal law treats illegal gratuities as a distinct and lesser offense than bribery.
Common Language
Modern common usage (Wiktionary): An additional payment given freely as thanks for service; also used euphemistically for obligatory add-on fees, and for bribes.
Historical common usage (Webster's 1913): Something given freely or without recompense; a free gift; or something voluntarily given in return for a favor or service.
Editorial note: The common meaning — a tip, freely given — is the starting point for legal analysis, but legal usage quickly diverges. In criminal law, "gratuity" is a term of art describing a corrupt payment to a public official, carrying none of the innocent connotation of a restaurant tip. In tax law, whether a payment qualifies as a gratuity (rather than wages or compensation) determines whether it is includable in gross income. Researchers should not carry the ordinary warm sense of the word into criminal or tax contexts.
Common Confusion
Gratuity vs. Bribe: These are distinct offenses under federal and many state criminal statutes. A bribe involves a quid pro quo — payment made to induce a specific official act. A gratuity is a payment made because of an official act, with or without a prior agreement. The distinction affects both the elements of proof and the applicable penalty. Historical sources often use "gratuity" loosely to mean any improper payment; researchers working with older materials should verify which concept the author actually means.
Gratuity vs. Bonus: Bouvier and Anderson both cross-reference BONUS, reflecting that older usage treated these as overlapping. In modern employment law they are distinguished: a bonus is typically a contractual or policy-based supplement to wages; a gratuity is discretionary. The overlap in historical dictionaries can mislead researchers tracing compensation disputes in older records.
Gratuity vs. Tip (tax context): In tax law, a tip is a subset of gratuity, but not all gratuities are tips. Mandatory service charges are generally wages, not gratuities, for withholding and reporting purposes. The Law Mind Tax Encyclopedia entry on Gross Income — Tips and Gratuities addresses this distinction directly.
Why It Matters in Research
The word "gratuity" is a false friend across legal subfields. A researcher in criminal law, tax law, and employment law will encounter the term in three largely non-communicating doctrinal traditions.
In criminal law research, the critical navigational task is distinguishing "gratuity" statutes from bribery statutes in your jurisdiction and era. Federal illegal gratuity doctrine developed separately from bribery doctrine, and the Supreme Court has addressed the line between them. State statutes vary significantly in whether they define gratuity as a separate offense or fold it into bribery.
In tax research, the voluntariness test for gratuities has a specific history. Whether an employer's payment to an employee or a customer's tip to a worker constitutes a gratuity (and thus potentially excludable from income under older doctrine) or compensation (taxable) generated substantial litigation. The 1986 Tax Reform Act effectively eliminated the income exclusion for tips, but the underlying definition question persists in other contexts.
In public employment and veterans' benefits research, older sources — particularly 19th-century materials — freely characterize government pensions and bonuses as "mere gratuities," language with constitutional implications for whether recipients have a protected property interest. This framing was used to argue that such benefits could be modified or withdrawn at will. That characterization has been substantially eroded in modern constitutional doctrine, but researchers reading older cases or treatises will encounter it frequently.
Anderson's cross-references (BONUS, BOUNTY, CHARITY, DEPOSIT, TRUST) signal that historical legal writers treated gratuity as a concept touching multiple doctrinal homes. A researcher should follow those threads; the entry itself is a pointer, not a treatment.
Historical Dictionary Support
Both Anderson and Bouvier treat "gratuity" by cross-reference only — neither provides a direct definition. This is itself informative: the term was considered self-evident in its core meaning (a free gift, without consideration) and its legal interest arose only at the margins where it intersected with other concepts: bonus, bounty, bribery, charitable transfers.
Webster's 1913 captures the pre-legal baseline well: a gratuity is simply something given freely. The legal tradition accepted this baseline and then spent its energy on boundary questions — how voluntary must the payment be, what is the effect of custom or expectation, and when does a gratuity become something legally consequential (a bribe, a taxable wage, a vested benefit).
Bouvier's cross-reference to BOUNTY is particularly useful for researchers in military pension and veterans' benefit history, where "gratuity" and "bounty" were used interchangeably for government payments to soldiers and their families through the 19th century. Both dictionaries predate the systematic development of federal tax law and criminal gratuity doctrine, so they offer limited direct guidance on those applications.
