Credit unions do pay taxes, just not federal corporate income tax. Because they are member-owned cooperatives with no outside shareholders, federal law exempts their earnings from income tax at the entity level. But they pay payroll taxes on their employees, property taxes on the buildings they own, sales and excise taxes on what they buy, and unemployment taxes like any other employer. And the members themselves pay income tax on the dividends their accounts earn.
So the honest answer to whether credit unions are “tax-free” is no. One important tax is off the table. Most of the others are not.
Why Credit Unions Skip Corporate Income Tax
The exemption traces back to the Federal Credit Union Act of 1934 and rests on how credit unions are built. A commercial bank has outside shareholders who expect it to maximize profits on their behalf. A credit union has no outside shareholders at all. Every depositor is a part-owner, and the institution is legally required to operate for the collective benefit of those members rather than to generate profit for investors.
The theory follows from the structure: a credit union’s earnings are really the members’ earnings, returned through lower loan rates, higher savings yields, or reduced fees. Congress decided that model shouldn’t be taxed at the entity level the same way a for-profit corporation is.
The legal basis depends on charter type. Federally chartered credit unions are treated as instrumentalities of the federal government under IRC Section 501(c)(1).1Internal Revenue Service.

Taxes Credit Unions Still Pay
Payroll Taxes
Every credit union with employees pays FICA taxes, meaning the employer’s matching share of Social Security and Medicare. The Social Security rate is 6.2% on wages up to the 2026 wage base of $184,500, and the Medicare rate is 1.45% on all wages with no cap.3Internal Revenue Service.

About Form 941, Employers Quarterly Federal Tax Return Credit unions also pay state unemployment taxes.5Employment & Training Administration. Unemployment Insurance Tax Topic
Property, Sales, and Excise Taxes
Credit unions pay property tax on the real estate they own: headquarters, branches, ATM kiosks on owned land. Even the Federal Credit Union Act, which offers the broadest tax shield available to any credit union, explicitly carves out real property and tangible personal property from its exemption.6GovInfo. 12 USC 1768 – Taxation Sales and excise taxes on equipment, office supplies, and services apply the same way they do to any business.
Unrelated Business Income Tax (State Charters Only)
Even tax-exempt organizations can owe federal income tax on revenue from activities unrelated to their exempt purpose. The IRS calls this unrelated business income, and it applies when an activity is a trade or business, carried on regularly, and not substantially related to the exempt function.7Internal Revenue Service. Publication 598 – Tax on Unrelated Business Income of Exempt Organizations
For credit unions, this matters only for state-chartered ones. A state-chartered credit union that earns income from activities outside its core financial services can owe tax on that income and must file Form 990-T to report it.8Internal Revenue Service. Instructions for Form 990-T Exempt Organization Business Income Tax Return Federal credit unions are not subject to the unrelated business income tax at all under IRC Section 511.1Internal Revenue Service.

Federal Charter Versus State Charter
The charter type matters more than most people realize, because it determines how far the tax exemption reaches.
Federal credit unions get an unusually broad shield. The Federal Credit Union Act exempts their property, franchises, capital, reserves, surpluses, and income from all taxation by federal, state, territorial, or local authorities. The only carve-out is for real property and tangible personal property, which stay taxable to the same extent as similar property owned by anyone else.6GovInfo. 12 USC 1768 – Taxation A federal credit union’s branch building faces local property tax; its income, reserves, and intangible assets do not.
State-chartered credit unions lack that blanket federal preemption. Their exposure to state and local taxes depends on individual state law. They also carry the unrelated business income risk that federal credit unions avoid entirely. To keep their federal income tax exemption, they must be formed under a state credit union law and maintain state-defined characteristics.9Internal Revenue Service.

What the Exemption Means for You as a Member
Lower Rates and Fewer Fees
The income tax exemption translates into real money, and loan pricing is where it shows up most clearly. NCUA data from late 2025 shows the average credit union rate on a 48-month new car loan was 5.32%, compared to 7.33% at banks. On a 48-month used car loan, credit unions averaged 5.53% versus 7.73% at banks, a spread of about two full percentage points.10NCUA. Credit Union and Bank Rates 2025 Q4 On a $30,000 used car loan over 48 months, that difference saves roughly $1,800 in interest.
The advantage extends to mortgages, personal loans, and credit card APRs, though the spread varies by product and market. On the fee side, credit unions are more likely to offer free checking, lower overdraft fees, and no monthly maintenance charges. Every dollar not paid in corporate tax or shareholder dividends is a dollar that can stay in the system for member benefit.
Your Own Tax Bill on Credit Union Earnings
The credit union’s exemption does not shelter your earnings. Credit unions call the returns on savings accounts “dividends,” but the IRS treats them as interest for tax purposes.11Internal Revenue Service. 1099-DIV Dividend Income If your credit union pays you $10 or more in dividends during the year, it will send you a Form 1099-INT, and you owe income tax on that amount at your ordinary rate.12Internal Revenue Service. About Form 1099-INT, Interest Income
Credit union earnings are taxed. Just at the member level rather than the corporate level.
How This Compares to a Bank
A commercial bank is a for-profit corporation that pays corporate income tax at the current federal rate of 21%. After-tax profits can be paid to shareholders as dividends (taxed again in the shareholders’ hands) or kept for growth. That double layer is the cost of the for-profit corporate model.
Credit unions skip the corporate layer because they have no shareholders to pay. Both types of institutions pay the same payroll taxes, the same property taxes, and the same unemployment insurance contributions. Corporate income tax is where they diverge, and industry estimates suggest credit unions collectively avoided roughly $4.3 billion in federal income taxes in 2025.
The Ongoing Debate Over the Exemption
The exemption has been contested for decades, and the arguments have sharpened as some credit unions have grown to rival mid-size banks. Banking trade groups argue the exemption made sense when credit unions were small, volunteer-run organizations, but no longer fits institutions managing billions in assets and offering the full range of commercial banking products. Some have pushed Congress to strip the exemption from credit unions above $1 billion in assets, pointing to credit unions using tax-free earnings to acquire community banks at prices taxed competitors cannot match.
Credit unions counter that the cooperative structure, not asset size, is what justifies the exemption. A credit union with $10 billion in assets still has no shareholders, still returns earnings to members, and still faces field-of-membership restrictions that banks do not. They argue that removing the exemption would force higher rates and fees on the consumers the exemption was designed to protect. Congress has not changed the exemption since its creation, but the debate resurfaces regularly.
