Credit unions operate under a tax exemption that regular banks do not have

Credit unions are member-owned cooperatives, not corporations. Because of this structure, the federal government does not tax their net income the way it taxes bank profits. A credit union keeps money it earns and returns it to members through lower loan rates, higher savings rates, or reduced fees. A bank takes its profits and distributes them to shareholders. The tax code reflects this difference: credit unions pay no federal income tax on earnings from lending and deposit services.

This exemption exists because credit unions were created to serve people who could not get loans from traditional banks. The idea was that a group of people with something in common—a workplace, a neighborhood, a profession—could pool their money and lend to each other at fair rates. The tax exemption was meant to help that mission survive. Whether that mission still applies to every credit union today is what the "don't tax my credit union" debate is really about.

Key Takeaways

  • Credit unions pay no federal income tax on earnings from their core lending and deposit business, while banks pay corporate income tax on all profits.
  • The tax exemption was designed to help credit unions serve people banks would not lend to, but some credit unions now operate like banks and serve the general public.
  • Banks argue the exemption is unfair because credit unions compete with them but do not pay the same taxes, giving them a cost advantage.
  • Credit unions argue they reinvest savings into members rather than shareholders, so the exemption reflects a real difference in how they operate.
  • Some states have already taxed credit union income or limited the exemption, and federal proposals to do the same appear regularly in Congress.

How the tax exemption works in practice

A credit union does not file a corporate income tax return the way a bank does. Instead, it files Form 990-T, which reports unrelated business income only—things like ATM fees, investment advisory services, or insurance sales that fall outside the core mission. The earnings from loans and deposits are not reported as taxable income at the federal level.

Credit unions do pay other taxes. They pay payroll taxes on employee wages, property taxes on buildings they own, and sales taxes on goods they buy. They also pay insurance premiums to the National Credit Union Administration (NCUA), which insures deposits the way the Federal Deposit Insurance Corporation (FDIC) insures bank deposits. But they do not pay federal income tax on the money they earn from taking deposits and making loans.

This means a credit union can charge lower interest on mortgages or car loans than a bank can, because the credit union does not need to set aside money for federal income taxes. That lower rate is the practical benefit members see.

Why banks say credit unions should be taxed

The American Bankers Association and other banking groups argue that the tax exemption no longer makes sense. They point out that many credit unions have grown very large—some have billions of dollars in assets and serve millions of members nationwide. These large credit unions compete directly with banks in the same markets, taking deposits and making loans to the same customers.

Banks say that if a credit union operates like a bank, takes deposits from the general public, and competes for the same business, it should pay the same taxes. They argue the exemption gives credit unions an unfair advantage: a credit union can undercut a bank's loan rates because it does not pay federal income tax, even though both institutions face similar costs. Over time, this shifts business from taxed banks to untaxed credit unions, reducing tax revenue.

Banks also note that the original purpose of the exemption—serving people banks would not lend to—no longer applies to many credit unions. A large credit union with millions of members is not serving an underserved population; it is serving whoever wants to join.

Why credit unions say the exemption should remain

Credit unions argue that the tax exemption is not a subsidy—it is a recognition that credit unions operate differently. A credit union's purpose is to serve its members, not to generate profit for shareholders. Any money a credit union earns stays in the credit union and goes back to members through better rates, lower fees, or improved services. A bank's purpose is to generate profit for shareholders, and that profit is taxed.

Credit unions also point out that they reinvest heavily in their communities. They lend to small businesses, offer financial education, and sponsor local nonprofits. If credit unions had to pay federal income tax, they would have less money to lend and would have to raise rates or fees to cover the tax bill. Members would lose the benefit of the exemption.

Credit union advocates also argue that the exemption does not give them an unfair advantage because banks have other advantages credit unions do not have. Banks can raise capital by selling stock; credit unions can only raise capital from members. Banks can offer investment products and insurance; credit unions face restrictions on what they can do. The exemption balances out these structural differences.

What states have done about credit union taxation

Some states have already decided to tax credit union income. South Carolina, for example, taxes credit union net income at the state level. A few other states tax credit unions on certain types of income or require them to pay a licensing fee. Most states, however, follow the federal model and do not tax credit union income.

State taxation does not override the federal exemption—a credit union can be exempt from federal income tax but still owe state income tax. This means a credit union in South Carolina pays state income tax but no federal income tax. The credit union's federal tax form still shows no federal income tax liability.

Federal proposals to tax credit unions

Congress has considered bills to tax credit unions several times over the past two decades. These proposals typically suggest taxing credit union income at the federal level, either at the full corporate rate or at a reduced rate. None of these bills have become law, but they appear regularly and gain support from banking groups each time.

The most common proposal would tax credit unions on income above a certain threshold or would limit the exemption to credit unions that meet specific criteria—for example, credit unions with fewer than a certain number of members, or credit unions that serve a specific underserved population. The goal is usually to preserve the exemption for small, mission-driven credit unions while taxing larger ones that operate like banks.

These proposals face opposition from credit union advocacy groups, which argue that any federal tax on credit unions would harm members and reduce lending. The debate has not been resolved, and the tax status of credit unions remains a point of disagreement between the banking and credit union industries.

How this affects you as a credit union member

If you use a credit union, the tax exemption affects you through the rates and fees you pay. Because your credit union does not pay federal income tax, it can offer lower loan rates and higher savings rates than a bank might offer. If credit unions were taxed at the federal level, those rates would likely change—loans would cost more and savings accounts would earn less.

The exemption also affects how much money your credit union can lend. A credit union that pays federal income tax has less money available to lend to members. This could mean longer wait times for loans, stricter lending standards, or reduced lending to riskier borrowers like small business owners or people with lower credit scores.

On the other hand, if you are a bank customer or shareholder, you might see the exemption as unfair. Banks pay federal income tax on their profits, which reduces the money available to pay dividends to shareholders or to invest in new branches and services. If credit unions were taxed the same way, banks would face less competition and might be able to offer better rates themselves.

Frequently Asked Questions

Do credit unions pay any taxes at all?

Yes. Credit unions pay payroll taxes on employee wages, property taxes on buildings, and sales taxes on purchases. They also pay insurance premiums to the NCUA. The exemption applies only to federal income tax on earnings from lending and deposits.

Can a credit union lose its tax exemption?

Yes, if a credit union fails to meet the requirements set by the IRS and NCUA. For example, if a credit union operates primarily for profit rather than member benefit, or if it fails to serve a defined membership, it could lose the exemption. This is rare, but it can happen.

Are all credit unions the same size and structure?

No. Credit unions range from very small (a few hundred members) to very large (millions of members and billions in assets). Some serve a specific group like employees of one company; others are open to anyone in a geographic area. This variation is part of why the tax debate is complicated.

If credit unions were taxed, would my rates go up when ready?

Not necessarily when ready, but over time, yes. A credit union would need to adjust rates and fees to cover the cost of federal income tax. How quickly this happens would depend on the credit union's financial position and how the tax was structured.

Why does this debate matter if no law has passed?

The debate matters because it shapes policy discussions and because some states have already acted. If a federal tax law passes, it would affect every credit union member in the country. Even without a law, the ongoing debate influences how credit unions operate and how they plan for the future.
