No, a credit union is not a bank. Under federal law the two are different kinds of institutions: a credit union is a nonprofit cooperative owned by the people who bank there, while a bank is a for-profit corporation owned by stockholders.1Office of the Law Revision Counsel. 12 USC 1752 – Definitions They look alike from the outside because they offer most of the same products and both insure your deposits up to $250,000. But the ownership model changes who the institution answers to, how it’s taxed, who can join, and what you’ll pay to borrow or earn to save.
Who Owns Each Institution
Federal law defines a credit union as a “cooperative association organized for the purpose of promoting thrift among its members and creating a source of credit for provident or productive purposes.”1Office of the Law Revision Counsel. 12 USC 1752 – Definitions When you open an account, you subscribe to at least one share of the credit union itself.2Office of the Law Revision Counsel. 12 USC 1759 – Membership You are a member-owner, not a customer. Any surplus the institution earns comes back to you through lower loan rates, higher savings yields, or reduced fees.
A commercial bank is a for-profit corporation. Its stockholders may never set foot in a branch, and the bank’s job is to generate returns for those investors. Profits flow out as shareholder dividends. Stockholders can sell their shares on the open market; a credit union member’s ownership ends when they close the account.
Governance follows the same split. Every federal credit union is run by a board of directors elected annually from the membership, with at least five directors serving at any time, and directors generally serve without pay.3Office of the Law Revision Counsel. 12 USC 1761 – Management Whether your balance is $500 or $500,000, you get one vote. At a bank, voting power tracks share ownership, and the average depositor has no formal voice unless they also hold stock.
Rates, Fees, and Taxes
Federal credit unions are exempt from federal, state, and local income taxes on their earnings, though they still pay property taxes on real estate and tangible assets.4Office of the Law Revision Counsel. 12 USC 1768 – Taxation Commercial banks pay the standard 21 percent federal corporate income tax plus applicable state taxes. Research from the Federal Reserve Bank of Richmond found roughly three-quarters of the credit union tax subsidy gets passed through to members as better rates and lower costs.
The gap shows up clearly in NCUA data from the fourth quarter of 2025:5National Credit Union Administration. Credit Union and Bank Rates 2025 Q4
- 48-month used car loan: 5.53% at credit unions versus 7.73% at banks
- 60-month new car loan: 5.44% at credit unions versus 7.41% at banks
- 30-year fixed mortgage: 6.26% at credit unions versus 6.50% at banks
- Classic credit card: 12.58% at credit unions versus 15.27% at banks
- 1-year CD ($10,000): 2.95% at credit unions versus 2.29% at banks
On a $30,000 used car financed over 48 months, the roughly 2.2 percentage point difference between a credit union and a bank works out to about $1,400 in extra interest over the life of the loan. Credit unions also tend to pay higher yields on certificates of deposit, though the advantage on basic checking and savings is smaller.
Who Can Join a Credit Union
Banks generally let anyone with valid identification open an account. Credit unions cannot. Federal law limits each credit union’s membership to a defined “field of membership” in one of three categories.2Office of the Law Revision Counsel. 12 USC 1759 – Membership
- Single common bond: one group sharing an occupational or associational connection, such as employees of a specific company or members of a professional organization.
- Multiple common bond: several groups, each with its own occupational or associational tie, combined under one charter.
- Community: anyone who lives, works, worships, or attends school in a defined local area such as a city, county, or neighborhood.6National Credit Union Administration. Choose a Field of Membership
Community charters have made credit unions far more accessible than they used to be. Many credit unions also admit the immediate family of existing members. A growing number partner with nonprofit foundations so anyone can qualify by making a small donation, often $5 to $25, to the affiliated organization. For dozens of large credit unions, the field-of-membership requirement is now close to a formality.
Deposit Insurance and Regulators
Both types of institution carry the same federal deposit insurance. The Federal Deposit Insurance Corporation insures deposits at banks up to $250,000 per depositor, per insured bank, for each account ownership category.7Federal Deposit Insurance Corporation (FDIC). Understanding Deposit Insurance The National Credit Union Administration performs the equivalent role for credit unions, with the National Credit Union Share Insurance Fund providing the same $250,000 coverage backed by the full faith and credit of the United States.8National Credit Union Administration. Share Insurance Coverage
The insurance works the same way at both. Individual accounts, joint accounts, IRA and Keogh retirement accounts, and trust accounts each receive separate coverage up to $250,000.8National Credit Union Administration. Share Insurance Coverage A married couple with individual accounts, a joint account, and separate retirement accounts at the same institution can have well over $250,000 protected. If your institution fails, you won’t lose a dollar up to those limits regardless of whether it’s a bank or a credit union.
The Consumer Financial Protection Bureau adds another layer for the largest institutions. The CFPB has supervisory authority over both banks and credit unions with more than $10 billion in assets.9Consumer Financial Protection Bureau. Institutions Subject to CFPB Supervisory Authority Below that threshold, consumer protection enforcement falls to the institution’s primary regulator: the NCUA for credit unions, and the OCC or state banking regulators for banks.
Where Banks Still Have the Edge
For day-to-day banking, the two are nearly indistinguishable. Both offer checking and savings accounts, certificates of deposit, mortgages, auto loans, personal loans, credit cards, and debit cards on the same major payment networks. Both support mobile check deposit, online bill pay, and contactless payments.
The gap opens up in physical reach and technology. Large national banks operate thousands of branches and proprietary ATM networks. A single credit union may have a handful of locations. Many credit unions close that gap by joining shared branching networks that let members walk into a participating credit union anywhere in the country and conduct transactions as if they were at their home branch, and by belonging to surcharge-free ATM networks with tens of thousands of machines. The technology gap has narrowed too, though some smaller credit unions still trail large banks on app features.
Business lending is the other place banks pull ahead. Federal law caps the total amount of member business loans a credit union can hold at the lesser of 1.75 times its actual net worth or 1.75 times the minimum net worth required to be classified as well capitalized. Banks face no equivalent portfolio cap on commercial lending. Some credit unions are exempt from the cap, including those chartered specifically for business loans, those serving predominantly low-income members, and those designated as community development financial institutions.10Office of the Law Revision Counsel. 12 USC 1757a – Limitation on Member Business Loans Loans fully secured by one-to-four-family homes and loans backed by government guarantees don’t count toward the cap. If you need a substantial commercial line of credit, though, a bank will usually have more room.
Which One Should You Use
The right pick depends on what you value most. Credit unions consistently offer lower borrowing costs and higher savings yields, and the cooperative structure means the institution’s incentives are aligned with yours rather than with outside shareholders. If you’re financing a car, building an emergency fund, or looking to trim fees, the math usually favors a credit union.
Banks offer broader geographic reach, more sophisticated commercial lending, and, at the largest institutions, technology platforms that smaller cooperatives can’t always match. If you travel constantly, run a business with complex credit needs, or want a single institution with branches on every other block, a bank may serve you better. Nothing stops you from using both. Many people keep a credit union for loans and savings where the rate advantage is real and a bank for the convenience of a large branch and ATM network, and that combination often gets the best of each model.
