Definition
Local taxes are taxes and assessments imposed by or for the benefit of a specific geographic subdivision of government — typically a county, municipality, school district, or special district — rather than by the state or federal government. They are levied under authority granted by the state to local governmental units and are generally limited in reach to persons, property, and transactions within that jurisdiction.
The term encompasses a wide variety of charges: property taxes on real and personal property within a city or county, local sales and use taxes, local income or wage taxes (in jurisdictions that permit them), special assessments for improvements benefiting particular parcels, and district-specific levies such as school taxes, fire district taxes, and sanitation district fees.
A key structural feature of local taxes is their derivative authority: local governments possess no inherent taxing power under American constitutional doctrine. Their authority to tax exists only to the extent the state legislature has granted it. This distinguishes local taxes from state taxes as a matter of constitutional architecture, even when the practical mechanics of collection look similar.
Common Language
Modern common usage (Wiktionary): "Local tax" in ordinary usage refers informally to any tax collected by a city, town, or county, as opposed to national or federal taxes.
Historical common usage (Webster's 1913): Webster's 1913 does not carry a discrete entry for "local tax," but uses "local" to mean "pertaining to a particular place; limited to a spot, district, or locality."
The gap worth noting: In common usage, "local" simply signals geography. In legal and tax research contexts, the term carries a structural meaning — it signals a specific tier of government with delegated, not inherent, authority. This distinction matters enormously when analyzing enabling legislation, preemption conflicts, and the scope of taxing power in any given jurisdiction.
Recognized Forms
/SUBTYPES
Ad valorem property taxes: The most historically dominant form of local taxation; assessed on real property at a percentage of assessed value. School district levies are typically property-tax-based.
Special assessments: Charges imposed on specific parcels to fund improvements (streets, sewers, sidewalks) that directly benefit those properties. Distinct from general taxation; the benefit rationale is central to their legal validity.
Local sales and use taxes: Percentage-based additions layered on top of state sales taxes. Common in home-rule states where municipalities have broad taxing authority.
Local income or wage taxes: Permitted in a minority of states (notably Pennsylvania and Ohio). These taxes on earned income at the municipal level are structurally unusual and heavily regulated by state enabling statutes.
Business and occupational taxes: Local licensing and privilege taxes on businesses operating within the jurisdiction.
Why It Matters in Research
Researchers encounter "local taxes" in at least three distinct legal contexts that require separate analytical frameworks, and conflating them is a persistent source of error.
First, in property and real estate law, local taxes typically means ad valorem property taxes and special assessments. Sources predating the mid-twentieth century will almost exclusively mean property taxes when they say "local taxes" — the modern proliferation of local sales taxes and local income taxes was not yet established. Historical materials must be read with this narrower referent in mind.
Second, in federal income tax research, "state and local taxes" (SALT) is a unified category for purposes of the itemized deduction under the Internal Revenue Code. Here the term carries a specific statutory meaning shaped by legislation, particularly the Tax Cuts and Jobs Act of 2017 and its SALT deduction cap. The Law Mind Tax Encyclopedia covers this directly.
Third, in constitutional and administrative law research, "local taxes" raises questions of enabling authority, preemption, and uniformity. State constitutions often contain uniformity clauses requiring that taxes of the same class be levied equally across a jurisdiction. Whether a particular local tax satisfies these clauses — or whether state law has preempted a local levy — is a distinct research problem from the tax's practical mechanics.
Researchers working in historical state materials should also be alert to the term "parochial taxes," which appears in older English and American sources as a synonym for local levies tied to parish or township administration. Black's definition explicitly includes this usage.
Finally, the treatment of local taxes in real estate transactions — including transfer taxes and documentary stamps imposed at the local level — requires attention to county and municipal ordinances that may not be captured in state statutory compilations.
Historical Dictionary Support
Black's Law Dictionary defines local taxes as "those assessments which are limited to certain districts, as poor-rates, parochial taxes, county rates, municipal taxes, etc." This definition is structurally accurate but reflects an older, largely English-influenced taxonomy. The enumerated examples — poor-rates, parochial taxes — are not operative categories in contemporary American law, though their functional equivalents (county levies, municipal assessments) remain central.
What Black's captures well is the core limiting principle: local taxes are geographically bounded and district-specific. What it does not capture — because the landscape did not yet demand it — is the constitutional derivative-authority doctrine that has become the organizing principle of American local tax law, nor the federal income tax dimension that gives "state and local taxes" a separate statutory significance.
No single historical dictionary entry fully accounts for the modern complexity of the term. Researchers relying solely on historical dictionary sources will have an accurate but incomplete picture that understates both the variety of local tax types and the preemption dynamics that govern them.
Jurisdictional Note
The scope of local taxing authority varies sharply by state. Home-rule states (like Illinois and Colorado) grant municipalities substantial independent taxing power, while Dillon's Rule states construe local authority narrowly, limiting local taxes to those expressly authorized by the legislature. This structural difference is outcome-determinative in preemption and authority disputes and must be identified at the outset of any state-specific research.
