A share savings account is the basic savings account you open when you join a credit union, and it does double duty as your proof of ownership in the institution. Federal law requires every credit union member to buy at least one share to establish membership, and your opening deposit, commonly $5, is that share. Keep it funded and you’re a member-owner with access to the credit union’s loans, checking, certificates, and everything else. Close it or let it drop below the required minimum and you lose your membership entirely.
Why It’s Called a Share
The word isn’t marketing. Federal law requires every credit union member to subscribe to at least one share of the institution to establish membership.1GovInfo. 12 USC 1759 – Membership Your initial deposit is that share purchase. The amount is small, typically $5, though some credit unions set par values up to $25 depending on their bylaws.
Because credit unions are not-for-profit cooperatives, any surplus earnings flow back to members through better rates, lower fees, or dividends rather than to outside investors. Ownership also comes with a vote. Each member gets one vote regardless of account balance, and members elect the volunteer board of directors that governs the credit union.
Ownership has a catch. The share savings account isn’t optional and it isn’t closable while you’re a member. You have to maintain at least the par-value balance to stay in. Let it fall below that floor and the credit union can terminate not just the account but your entire relationship with the institution, including any loans, checking, or other products tied to your membership.
Once your share savings account is open, it unlocks the rest of the lineup. A share draft account is the credit union’s version of a checking account.2Consumer Financial Protection Bureau. What Is a Credit Union Share Draft Account? Is It a Checking Account? A share certificate is its version of a CD. Both carry the “share” label because they extend from the same ownership stake.
How Your Money Grows: Dividends, Not Interest
Funds in a share savings account earn dividends, not interest. The distinction is legal rather than practical. Because you’re an owner, the return you receive represents your portion of the credit union’s net earnings, not a fee paid to a depositor. The board of directors declares dividend rates at intervals it sets, and it can pay different rates on regular shares, share certificates, and share draft accounts.3Office of the Law Revision Counsel. 12 USC 1763 – Dividends
Most credit unions calculate dividends on average daily balance and compound monthly or quarterly. As of mid-2025, the national average dividend rate on a regular share savings account was 0.19%, compared to 0.32% on a comparable bank savings product.4National Credit Union Administration. Credit Union and Bank Rates 2025 Q2 Credit unions often push value to members through lower loan rates and fewer fees rather than higher savings dividends.
The IRS treats credit union dividends as interest income. If yours exceed $10 in a year, the credit union will issue a Form 1099-INT and you’ll owe ordinary income tax on the amount.5Internal Revenue Service. Topic No. 403, Interest Received The agency is explicit: dividends on share accounts at credit unions are taxable interest regardless of what the credit union calls them.6Internal Revenue Service. About Form 1099-INT, Interest Income
Federal Insurance on Your Balance
Your share savings account is federally insured by the National Credit Union Share Insurance Fund, run by the National Credit Union Administration. The fund carries the full faith and credit of the United States government, the same backing behind FDIC insurance at banks.7National Credit Union Administration. Share Insurance Coverage
The standard coverage limit is $250,000 per member, per insured credit union, in each ownership category.8Office of the Law Revision Counsel. 12 USC 1787 – Payment of Insurance Ownership categories let you stack coverage well beyond that ceiling at a single credit union. The main ones:
- Single ownership accounts: $250,000 total across all individually owned accounts (regular shares, share drafts, money market accounts, and share certificates combined).
- Joint accounts: each co-owner gets $250,000 in coverage for their combined interest in all joint accounts, so a two-person joint account carries up to $500,000.
- Revocable trust accounts: $250,000 per named beneficiary, separate from the owner’s individual coverage.
- IRAs and certain retirement accounts: $250,000 per member, separate from every other category.
A married couple using single, joint, and trust categories at one credit union can insure well over $1 million.9National Credit Union Administration. How Your Accounts Are Federally Insured NCUA coverage applies to all federal credit unions and most state-chartered ones, though a small number of state-chartered credit unions carry private insurance instead.10MyCreditUnion.gov.

Getting Money In and Out
Before 2020, federal Regulation D limited savings accounts to six electronic withdrawals per month. The Federal Reserve eliminated that cap in April 2020 and has no plans to reimpose it. Individual credit unions can still enforce their own limits, though. Some have dropped them entirely; others still cap electronic transfers at six per month and charge $5 to $15 for each excess transaction. Ask your credit union what its policy actually is.
Where limits exist, they typically apply to electronic transfers like online bill pay, automatic transfers between accounts, and overdraft protection sweeps. ATM withdrawals, in-person teller transactions, and incoming deposits are generally exempt.
You can always pull out everything above your par value. The funds are yours to use however you want, as long as you leave the required share amount in place. If you drop below it, you’ll get a notice and a window to restore the balance before the credit union closes the account and ends your membership.
For access beyond your home branch, many credit unions participate in the CO-OP Shared Branching network, which lets you make deposits, withdraw cash, transfer funds, and make loan payments at thousands of other participating credit unions with just your credit union’s name, your account number, and a photo ID.11SharedBranching.org.

How To Open One
Every credit union defines a field of membership that determines who can join. The common bond might be geographic (you live or work in a defined area), employer-based (your company partners with the credit union), or associational (you belong to a qualifying organization). Most credit unions also extend eligibility to family members of existing members. The credit union’s website will spell out its criteria.
Once you confirm eligibility, the application looks like opening any bank account. You’ll need a government-issued photo ID such as a driver’s license, passport, or state ID; proof of address like a utility bill, lease, or bank statement; your Social Security Number or Taxpayer Identification Number; and the initial deposit, typically $5 to $25. Once identity is verified and the deposit clears, you’re a member-owner.
What Happens if You Stop Using It
Walk away from the account and the credit union will eventually classify it as dormant or inactive. Most credit unions charge a monthly dormancy fee, and they’re required to disclose it when you open the account.12National Credit Union Administration. Permissibility of Closing Inactive Accounts The practical risk is that those fees chip away at the balance until it drops below par value, at which point the credit union can terminate your membership after giving you notice.
If the account sits untouched long enough, state unclaimed property laws take over. The credit union must try to reach you, and if it can’t, the funds get turned over to the state. Recovering them means filing a claim with your state’s unclaimed property office.
Separately, the board of directors can adopt a policy to expel members for nonparticipation, such as not voting in elections, not maintaining shares, or not using any products. Members must receive written notice of any such policy at least 30 days before it takes effect.13Office of the Law Revision Counsel. 12 USC 1764 – Expulsion and Withdrawal
