Definition
Omitted property is real or personal property that has been entirely left off the tax assessment rolls — not assessed at all for a given tax year. The term arises primarily in property taxation law and describes property that the assessing authority failed to include in its valuation and levy process.
A critical distinction governs the term's application: property that was assessed but assigned to the wrong taxing subdivision or municipality does not qualify as omitted property. The error in such cases is one of misallocation, not omission. True omitted property is property that received no assessment whatsoever, leaving the taxing authority with no record of it for that cycle.
When omitted property is discovered, most jurisdictions permit a supplemental or back assessment to capture the unpaid taxes, often subject to statutory time limits on how many prior years may be reached.

Common Confusion
Omitted property is sometimes confused with undervalued or incorrectly assessed property. These are distinct situations. Undervalued property appears on the rolls but at a value lower than it should be — a matter addressed through reassessment or appeal. Incorrectly allocated property appears on the rolls but under the wrong jurisdiction. Neither qualifies as omitted property under the strict definition. The distinction matters because the legal remedies, the responsible assessing authority, and the applicable statutes of limitation often differ across these three situations.

Why It Matters in Research
Researchers working with historical tax records, title abstracts, or property valuation disputes will encounter this term most often in two contexts: back-tax proceedings and title searches where gaps in the assessment record raise questions about ownership or encumbrance.
The definitional boundary between omitted property and misallocated property — established clearly in Bouvier's single-sentence treatment — is operationally significant. Counsel and researchers examining state taxation statutes should not assume that a legislative reference to "omitted property" reaches property assessed in the wrong district. Courts have drawn this line firmly, and the Kentucky authority cited in Bouvier's reflects a broader judicial consensus.
Temporal traps exist in historical sources. Nineteenth and early twentieth-century assessment statutes used varying terminology — "escaped property," "omitted lands," "unassessed property" — that may or may not map onto the modern technical definition of omitted property. A researcher reading an 1880s state tax code should not assume that "escaped" property and "omitted" property carry identical legal consequences under that jurisdiction's scheme.
Jurisdictional variation in back-assessment windows is substantial. Some states permit assessment of omitted property going back five or more years; others limit recovery to the current and one prior year. When researching a title or a tax lien dispute, the applicable state's omitted property statute controls — the common law baseline is thin and largely unhelpful without reference to local code.
The term also surfaces in estate and probate contexts, where "omitted property" can describe assets not listed in an inventory or not transferred by a will or trust instrument. This usage is distinct from the tax law meaning and governed by an entirely different body of doctrine. Researchers should identify which legal domain they are working in before assuming the term's meaning in a given source.

Historical Dictionary Support
Bouvier's Law Dictionary offers a concise, functionally precise definition: property not assessed at all. Bouvier's immediately supplies the limiting rule — misallocated property does not qualify — and supports it with citation to a Kentucky decision. This is useful as far as it goes, but Bouvier's treatment is narrow. It reflects the taxation context almost exclusively and does not acknowledge the probate or estate administration usage of the same phrase, which was well-established by the time Bouvier's editions were in wide circulation.
The Bouvier's entry also appends the Latin maxim OMNIA PERFORMAVIT as a sequential entry, with no substantive connection to omitted property — a layout artifact researchers should not read as implying any doctrinal relationship between the two concepts.
Historical legal dictionaries generally do not address the procedural mechanics of back-assessment for omitted property in any depth, nor do they grapple with the jurisdictional variation in limitations periods. Researchers relying solely on dictionary sources for this term will need to supplement with state taxation codes and treatises on property assessment law to get operationally useful guidance.

Jurisdictional Note
Most U.S. states have omitted property statutes that specify the procedure and time window for back-assessing property left off the rolls. These statutes vary significantly in scope, limitations periods, and whether the property owner receives notice and an opportunity to contest the supplemental assessment. The term also appears in uniform trust and probate acts, where it describes assets not included in a decedent's estate plan, governed by state-level adoption and modification of those uniform acts.
