The difference between federal and state-chartered credit unions comes down to who issues the charter and who writes the rules. A federal credit union is chartered and supervised by the National Credit Union Administration under a single national rulebook. A state-chartered credit union is chartered by a state financial regulator and follows that state’s laws on membership, lending, taxes, and governance. Both types can look identical from the teller window, but the charter shapes what the institution is allowed to do behind the scenes.
Who Regulates Each Type
Federal credit unions have one regulator. Congress created the NCUA in 1970 to charter, supervise, and insure them nationwide.1National Credit Union Administration. About the National Credit Union Administration Safety-and-soundness exams for federal credit unions in good standing run on a 14- to 18-month cycle, with more frequent visits for institutions that have weak ratings, outstanding enforcement actions, or assets of $10 billion or more.2National Credit Union Administration. Exam Scheduling Policy Changes
State-chartered credit unions answer to a state financial regulator, usually housed in a Department of Financial Institutions or Division of Banking. State examiners set their own schedules; some roughly mirror the NCUA’s cycle, others allow longer intervals for well-rated institutions. The NCUA still holds backup examination authority over any state-chartered credit union that carries federal deposit insurance, though it usually coordinates with the state and may examine those institutions as infrequently as once every five years.2National Credit Union Administration. Exam Scheduling Policy Changes
Both charter types pay supervisory fees, just to different places. Federal credit unions pay an annual operating fee to the NCUA calculated as a percentage of total assets.3eCFR. 12 CFR 701.6 – Fees Paid by Federal Credit Unions State-chartered institutions pay assessments to their state regulator under formulas that vary by jurisdiction. These costs fold into overhead and can influence the rates and fees members see.
Who Can Join
Every credit union has to define its field of membership, and the federal rules are more prescriptive than most state ones. A federal credit union chooses one of three options: a single common bond (one employer or association), a multiple common bond (several defined groups), or a community charter tied to a geographic area. The NCUA caps community charters at a combined or core-based statistical area with a population of 2.5 million or less, or a rural district of 1 million or less.4National Credit Union Administration. Community Charter Conversions and Expansions Adding a new group requires a formal application to the NCUA.
State charters often allow broader geographic boundaries — sometimes entire counties or regions — and a wider variety of shared interests for common-bond charters. If a credit union wants to serve a large metro area or a diverse membership, state rules may make that easier, which is one of the practical reasons an institution chooses a state charter.
Family eligibility differs too. The NCUA defines eligible family as relatives by blood or marriage, plus foster and adopted children, who live in the same household as an existing member.5National Credit Union Administration. Bylaw Definition – Immediate Family Member That household requirement excludes adult children, parents, or siblings who live elsewhere. State charters frequently define family more broadly and may let relatives who don’t share a household join.
Interest Rates and Lending Limits
Federal law sets a default 15% per year ceiling on all federal credit union loans, but the NCUA Board can raise it temporarily for up to 18 months at a time when market rates threaten institutional health.6Office of the Law Revision Counsel. 12 USC 1757 – Powers As of mid-2026, the Board has extended a temporary 18% ceiling through September 2027.7National Credit Union Administration. NCUA Board Extends Loan Interest Rate Ceiling The cap has been renewed continuously for years, so 18% is the practical federal ceiling.
State-chartered credit unions follow their own state’s usury laws instead. To keep them from being stuck with more restrictive rules, roughly three dozen states have enacted “wildcard” or parity statutes that let state charters match the powers of their federal counterparts. In practice, many can adopt the same rate ceilings federal credit unions use, though some must first apply to the state regulator.
Payday Alternative Loans
One product exists only in the federal framework: the Payday Alternative Loan. Federal credit unions can offer PAL I loans between $200 and $1,000 with terms of one to six months, charging up to 28% interest plus an application fee capped at $20.8eCFR. 12 CFR 701.21 – Loans to Members and Lines of Credit to Members The borrower must have been a member for at least one month, and the loan cannot be rolled over. A PAL II version allows larger amounts and longer terms. State-chartered credit unions have no standardized equivalent, though individual states may authorize similar small-dollar products.
Member Business Loans
Federal law caps total member business loans at any federally insured credit union at 1.75 times the credit union’s actual net worth, or 1.75 times the minimum net worth needed to be well-capitalized, whichever is less.9Office of the Law Revision Counsel. 12 USC 1757a – Limitation on Member Business Loans Because the well-capitalized minimum is 7% of assets, the formula works out to roughly 12.25% of total assets in practice. The limit applies to state-chartered credit unions with federal insurance too, though some states let their credit unions exceed it if they hold strong capital reserves.
Loan Maturity
Federal credit unions face a general 15-year maturity cap, with exceptions. First-lien mobile home loans and second mortgages on a member’s home can run up to 20 years, and residential real estate loans up to 40 years.8eCFR. 12 CFR 701.21 – Loans to Members and Lines of Credit to Members State-chartered credit unions follow state maturity rules, which may be more permissive for certain loan types.
Tax Treatment
This is one of the sharpest differences, and most members never think about it. Federal credit unions have a sweeping exemption: their income, capital, reserves, and surpluses are exempt from all federal, state, and local taxation. Real property and tangible personal property get taxed like anyone else’s.10Office of the Law Revision Counsel. 12 USC 1768 – Taxation Because the exemption comes from federal law, no state can override it.
State-chartered credit unions get their federal income tax exemption through Internal Revenue Code Section 501(c)(14)(A), which covers credit unions organized without capital stock and run on a nonprofit, mutual-benefit basis.11Internal Revenue Service. Exempt Organizations CPE – Credit Unions The catch: state charters are subject to unrelated business income tax on revenue from activities outside their core mission, such as nonmember ATM fees, insurance commissions, and financial services sold to nonmembers. A state-chartered credit union with more than $1,000 in gross unrelated business income must file IRS Form 990-T. Federal credit unions, as federal instrumentalities, aren’t subject to this tax at all.
State and local tax treatment of state-chartered credit unions varies too. Some states exempt them from state income tax entirely; others impose franchise taxes or other assessments. For a credit union weighing charter options, these differences matter, especially if it earns significant income from ancillary services.
Deposit Insurance
All federal credit unions must insure member deposits through the National Credit Union Share Insurance Fund, which covers up to $250,000 per individual account holder. IRA and Keogh accounts get their own separate $250,000 in coverage, and a member’s combined interest in joint accounts is insured up to another $250,000. The insurance carries the full faith and credit of the United States government, and federal law requires every federally insured credit union to display the official NCUA insurance sign at teller stations, on its website, and wherever it accepts deposits.12National Credit Union Administration. Share Insurance Coverage
Most state-chartered credit unions also carry this federal insurance. The NCUA reports it covers the overwhelming majority of state-chartered institutions. But a handful of states let their credit unions use private deposit insurance instead. The best-known private insurer, American Share Insurance, offers $250,000 in coverage per account. The critical difference is that private insurance is not backed by the federal government. A credit union using private coverage must disclose that fact on account statements and marketing materials. The clearest signal is usually the absence of the NCUA insurance logo.
Board Compensation
Federal credit unions run on volunteer governance. Federal law prohibits paying directors for board service, with one narrow exception: the board may designate a single officer, typically the treasurer or chair, to be compensated if the bylaws spell out the specific duties.13eCFR. 12 CFR Part 701 – Organization and Operation of Federal Credit Unions Directors can be reimbursed for travel and out-of-pocket expenses, and the credit union can provide health and accident insurance tied to risks of the role.
State-chartered credit unions follow their state’s governance rules. Some states copy the federal model and prohibit director pay. Others allow boards to compensate directors, sometimes with few restrictions. For large, complex credit unions where the board demands significant time, being able to pay directors can matter in recruiting qualified people.
Switching Charters
A credit union isn’t locked into its charter. Converting from federal to state (or the reverse) is a defined process with real paperwork. The NCUA publishes specific forms for a federal-to-state conversion, including a notice of meeting, a ballot, and an affidavit documenting the vote.14National Credit Union Administration. Chartering, Field of Membership, and Conversion Resources Under federal law, a simple majority of members who vote is enough to approve the switch.15eCFR. 12 CFR 708a.113 – Voting Guidelines Some states require a two-thirds supermajority when a state-chartered credit union wants to convert to a federal charter, so the threshold depends on the direction and the state.
Credit unions most often convert to gain broader lending powers, more flexible field-of-membership rules, or a different tax or governance structure. The decision usually comes down to a practical question: which regulator’s framework best fits the institution’s business plan and the community it wants to serve? For members, the same question runs in reverse. The charter tells you which rulebook governs your rates, who insures your deposits, and how far the credit union can stretch to serve people like you.
