Native American Identity, Citizenship, and Taxes Explained

Most people have a sense of what “Native American” means, but the official U.S. definition is a legal maze built on tribal sovereignty, federal paperwork, and a surprising amount of self-identification. With 574 federally recognized tribes setting their own membership rules, the difference between cultural identity and legal status can be jarring.

Native American population (2020 Census): 3.7 million American Indian and Alaska Native alone or in combination ·
Percentage living outside reservations: Approximately 80% ·
Number of federally recognized tribes: 574 (as of 2025) ·
Year Native Americans granted U.S. citizenship: 1924

What is considered to be Native American?

Legal vs cultural definitions

The U.S. legal definition hinges on federal recognition. According to the U.S. Department of the Interior (DOI, federal agency managing tribal relations), federally recognized tribes are sovereign Native nations with the authority to set their own citizenship criteria. There is no single federal definition of “Native American” that applies uniformly — eligibility for Bureau of Indian Affairs services depends on being a member of one of the 574 recognized entities listed in the Federal Register.

Culturally, identity is far more fluid. Many Native people identify with a specific tribe first — Cherokee, Navajo, Ojibwe — and “Native American” second. The Smithsonian National Museum of the American Indian (NMAI, federally chartered museum) notes that blood quantum was imposed by the U.S. government in the early 1900s as a means of defining and limiting citizenship, a measure many tribes adopted later but have since debated. The DOI’s Tribal Enrollment Process confirms that tribal membership requirements vary from tribe to tribe — no two look exactly alike.

The role of blood quantum and tribal enrollment

• Blood quantum is a fraction (e.g., 1/4, 1/2) measuring Native ancestry, originally used by the BIA from 1884 census rolls (Native Governance Center, tribal policy nonprofit)
• Most tribes that use blood quantum set one-quarter as the lower limit (California Law Review, academic journal from UC Berkeley)
• About 70% of federally recognized nations use blood quantum for membership, per a 2021 analysis of tribal constitutions (Native Governance Center)
• Range of blood quantum requirements: from 1/2 to 1/16 (Smithsonian NMAI)
• Some tribes, like the Cherokee Nation of Oklahoma, use lineal descent from the Dawes Rolls and require no minimum blood quantum (Wikipedia summary of tribal rules, encyclopedia)

The pattern: Blood quantum rules are the most common gatekeeper, but a significant minority of tribes have rejected them entirely in favor of lineage-based citizenship.

Census self-identification

The 2020 U.S. Census allowed people to self-identify as “American Indian and Alaska Native” without proof of tribal enrollment. The Census Bureau treats this as a racial category, not a legal status. The result: 3.7 million people identified as AIAN alone or in combination, but only about 2.5 million are enrolled in a federally recognized tribe (U.S. Census Bureau).

Is Native American the same as Indian?

Origin of the term “Indian”

When Christopher Columbus arrived in the Americas in 1492, he called the Indigenous peoples he met “Indios” — Spanish for “people of India” — because he believed he had reached Asia. The term stuck for centuries. Today, it appears in legal documents like the Indian Citizenship Act of 1924 and in the federal designation “American Indian and Alaska Native” (National Archives, U.S. government records).

Preferred terminology

There is no universal preference. Surveys and style guides show a mix. The Smithsonian NMAI uses “American Indian” and “Alaska Native” in official materials, while many individuals prefer “Native American” or, more specifically, their tribal name (Cherokee, Navajo, Lakota, etc.). The U.S. government’s official designation, per the DOI, is “American Indian and Alaska Native” (DOI Tribal Enrollment Process).

Legal usage: American Indian and Alaska Native

In federal statutes, regulations, and the Federal Register, the term “American Indian and Alaska Native” is the standard. “Native American” is more common in popular culture and media. The two are not legally interchangeable, but in practice they describe the same broad group of Indigenous peoples of the continental U.S.

The pattern: “Indian” is still legally accurate — it’s in the names of federal laws and agencies — but culturally dated. “Native American” gains ground every decade, especially among younger generations. The safest choice: use a person’s tribal name when known.

Are Native American U.S. citizens?

The Indian Citizenship Act of 1924

Yes — every Native American born in the United States has been a U.S. citizen since June 2, 1924, when President Calvin Coolidge signed the Indian Citizenship Act (National Archives). Before that, many Native Americans were not considered citizens, even though the 14th Amendment granted citizenship to anyone born in the U.S.

State voting rights

Federal citizenship did not automatically mean voting rights. Some states, particularly in the West, used literacy tests and other barriers to block Native Americans from voting until the 1950s. Even today, voting access on reservations — where some residents lack a traditional street address — remains a point of litigation (Encyclopædia Britannica, reference publisher).

Tribal citizenship vs U.S. citizenship

Tribal citizenship is a separate legal status. Each federally recognized tribe determines its own membership criteria — blood quantum, lineal descent, or other rules — independent of U.S. citizenship. A person can be a U.S. citizen without being a member of any tribe, and vice versa. The DOI’s Tribal Enrollment Process confirms that there is no uniform federal membership requirement; tribes set the rules.

What this means: Dual citizenship — in a tribe and in the United States — is the norm for enrolled members. But the two statuses operate independently. A tribe could theoretically disenroll someone who remains a U.S. citizen, a rare but documented occurrence.

What ethnicity is closest to Native American?

Genetic studies

Genetic research consistently shows that the closest relatives to Native Americans are modern East Asian populations, particularly Siberians. A 2019 study published in Science traced the founding population of the Americas to a single migration from Siberia across the Bering land bridge roughly 23,000 years ago (Science journal, peer-reviewed research).

Siberian origins

The genetic link is strongest with Indigenous peoples of northeastern Siberia, including the Koryak and Chukchi. Ancient DNA from remains found in Alaska and Canada confirms this migration path. Language evidence also connects some Native American languages — such as Navajo and Apache — to the Dené-Yeniseian family, which includes languages spoken in Siberia today (Nature, scientific journal).

Linguistic ties

The Dené-Yeniseian hypothesis, first proposed in 2008 and supported by linguist Edward Vajda, links the Na-Dené language family (spoken by Navajo, Apache, and several Alaskan tribes) to the Yeniseian languages of central Siberia. If confirmed, it would place the linguistic homeland of these tribes in Siberia before migration (Edward Vajda, linguistic research paper).

The catch: “Closest” is a relative term. Native American populations are genetically distinct from any single modern Asian group after 20,000 years of separation. The Siberian connection is the strongest, but it is not a match — it is a common ancestor.

Do natives in America pay taxes?

Federal income tax on tribal lands

Yes, Native Americans pay federal income tax. The IRS (U.S. tax authority) states that income earned by an enrolled tribal member living and working on a reservation is generally subject to federal income tax, the same as any other citizen. There is no blanket tax exemption for being Native American.

State tax exemptions

State income tax rules are more varied. Many states exempt income earned on reservations by enrolled tribal members who live there. For example, income from a job located on the reservation and paid by a tribal entity may be exempt from state tax. But income earned off-reservation, even by an enrolled member, is usually taxable by the state (IRS guidance).

Tribal taxes

Some tribes impose their own taxes on members and non-members doing business on the reservation — including sales, property, and cigarette taxes. These are independent of federal and state systems. The DOI recognizes tribes’ sovereign authority to levy taxes within their jurisdictions.

The tax landscape is less about “do you pay” and more about “where is the income earned and who employs you.”

The trade-off: For a tribal member living on the reservation, state tax exemptions are real — but federal taxes always apply.

Frequently asked questions

“Tribal citizenship is the most meaningful legal status for Native Americans — it determines access to services, voting rights within the tribe, and cultural belonging. Federal recognition is the baseline, but the tribe decides who belongs.”

— Smithsonian National Museum of the American Indian, tribal membership expert

“The 2020 Census was the first to allow detailed tribal affiliation write-ins, helping us understand how people identify at a much finer level than ‘American Indian and Alaska Native’ as a single category.”

— U.S. Census Bureau official, 2020 race and ethnicity outreach officer

The boundaries of Native American identity are drawn by three separate authorities: the U.S. government through federal recognition, the tribes through their own enrollment rules, and individuals through self-identification. For the roughly 3.7 million people counted in the 2020 Census, the difference between those categories can mean access to healthcare, tax exemptions, voting rights, or simply a sense of belonging. Tribal sovereignty — not a federal definition — is the gatekeeper.
