Definition
Death duties are taxes imposed on the transfer of property occasioned by a person's death. The term is a collective label for a family of related levies rather than a single tax. Under English law — the system from which the phrase derives most of its technical content — the principal duties historically collected under this heading were:
1. Estate Duty: A tax on the aggregate value of a deceased person's estate passing at death, introduced by the Finance Act 1894.
2. Succession Duty: A tax on the value of property received by a successor under a disposition taking effect at death.
3. Legacy Duty: A tax on legacies and shares of residue received from a deceased's personal estate, varying by the relationship between testator and legatee.
4. Probate Duty: An older charge, still nominally payable in limited circumstances, assessed in connection with the grant of probate.
5. Settlement Estate Duty: A duty applicable from 1894 to 1914 on settled property passing at death.
6. Account Duty and Temporary Estate Duty: Further supplementary charges, both substantially or wholly abolished.
The animating principle running through all forms of death duty, as Bouvier's notes, is that death itself is the generating event — it is the act of dying, or more precisely the transmission of property that death triggers, that calls the taxing power into being.

Common Language
Modern common usage (Wiktionary): Plural of "death duty" — the ordinary English phrase for a tax levied on a deceased person's estate.
Historical common usage (Webster's 1913): Not independently defined; the concept was understood colloquially as a charge exacted by government upon a person's estate at death.
The gap between common and legal usage is one of precision, not kind. In ordinary speech, "death duties" functions as an informal synonym for any inheritance or estate tax. In legal and historical sources, it is a term of art denoting a specific cluster of distinct English fiscal charges, each with its own base, rate, and statutory history. A researcher who treats the phrase as a simple synonym for "estate tax" will miss important distinctions between succession duty, legacy duty, and estate duty — levies that operated differently, applied to different property, and were abolished at different times.

Common Confusion
DEATH DUTIES vs. ESTATE TAX vs. INHERITANCE TAX: These terms are frequently used interchangeably in modern writing, but they are not equivalent. "Death duties" is the English collective term covering multiple levies. "Estate tax" (the dominant American term) is assessed on the decedent's gross estate before distribution. "Inheritance tax" is assessed on the individual beneficiary's receipt and varies by the beneficiary's relationship to the decedent. Under the English system, succession duty and legacy duty functioned more like inheritance taxes, while estate duty functioned more like an estate tax. Conflating these in historical research produces anachronistic misreadings.
DEATH DUTIES vs. WRONGFUL DEATH DAMAGES: No legal connection. "Death duties" are fiscal instruments of property transmission law. "Wrongful death" is a tort cause of action for compensatory damages. The shared word "death" is the only link.

Recognized Forms
/SUBTYPES
As documented in Bouvier's, the recognized English death duties were:
- Estate Duty (principal charge, 1894 onward)
- Succession Duty
- Legacy Duty
- Probate Duty
- Settlement Estate Duty (1894–1914)
- Temporary Estate Duty (abolished)
- Account Duty (effectively defunct)
Each operated under distinct statutory authority and was not simply a variant label for the same tax.

Why It Matters in Research
Historical documents, particularly English legal texts, treatises, and parliamentary materials from the nineteenth and early twentieth centuries, use "death duties" to reference this entire taxonomy simultaneously. A researcher encountering the phrase in, say, an 1895 conveyancing treatise cannot assume it refers only to estate duty; succession duty and legacy duty may both be in play, and the analysis turns on which category of property and which class of beneficiary is involved.
The abolition timeline matters. Settlement estate duty disappeared in 1914. Estate duty itself was eventually replaced in England by Capital Transfer Tax (1975) and then Inheritance Tax (1986). Sources written after these reforms may use "death duties" loosely to describe what is now technically "inheritance tax" — a compound anachronism that can distort historical comparison.
American researchers should note that U.S. sources rarely use this phrase. When it appears in American legal materials, it almost always signals either a citation to English authority or a comparative tax law discussion. The Internal Revenue Code uses "estate tax" and "gift tax" — not "death duties."
The theoretical foundation identified by Bouvier's — that the power to tax derives from the act of transmission, not merely the fact of ownership — has doctrinal significance. It shaped how courts analyzed whether particular transfers (gifts causa mortis, joint tenancies, life insurance proceeds) fell within or outside the death duty net. Researchers tracing the constitutional and statutory history of American estate taxation will find this principle in early treatises arguing for or against the federal estate tax's validity.

Historical Dictionary Support
Bouvier's Law Dictionary provides the most substantive historical treatment available in the corpus. It identifies the core categories of English death duty with reasonable precision, establishes the 1894–1914 window for Settlement Estate Duty, and correctly notes that probate duty survived (in limited form) after the main rationalization of the system. Bouvier's articulation of the foundational principle — that death is "the generating source from which the particular taxing power takes its being" — is an accurate and useful distillation of the theoretical consensus across Roman, Continental, and English law.
What Bouvier's does not provide is granular statutory detail: the Finance Act 1894 rates, the mechanics of aggregation under estate duty, or the specific relationships triggering differential legacy duty rates. For that level of precision, a researcher must go to English fiscal statutes and contemporaneous English treatises (Hanson on Death Duties being the standard practitioner reference of that era). Bouvier's entry on SUCCESSION, SINGULAR cross-references suggest awareness of the broader doctrinal context, though that entry in the corpus appears truncated.

Jurisdictional Note
The phrase "death duties" is principally English and Commonwealth in origin and usage. The United States federal system uses "estate tax" (IRC Chapter 11) and separately taxes beneficiaries through "inheritance tax" at the state level — though not all states impose one. Researchers working in Australian, Canadian, or other Commonwealth legal materials from the twentieth century will encounter "death duties" as the operative phrase, though most Commonwealth jurisdictions abolished them between the 1970s and 1980s.
