How to Separate a Joint Bank Account: Steps, Taxes, and FDIC

To separate a joint bank account, you generally have two options: close the account and divide the balance, or ask the bank to remove one owner’s name so the other keeps sole control. Either co-owner can usually close the account alone, but removing a name almost always requires the consent of the person being removed.¹² Before you act, read your account agreement, redirect any automatic payments, and think through a few tax and insurance consequences that catch people off guard.

Start With Your Account Agreement

Your deposit account agreement, sometimes called the terms and conditions, spells out how the bank handles closures and ownership changes. It’s the document you signed (or accepted electronically) when the account was opened. Look for language on whether one owner can close the account alone, whether written consent from all owners is required for changes, and what fees apply. You can usually find a copy in the bank’s app, on its website, or by asking at a branch.

Note how the account is titled. Joint accounts are commonly held as joint tenancy with right of survivorship, meaning the balance passes to the surviving owner at death, or as tenants in common, where each owner holds a defined share that goes to their estate.³ Both types can be separated during the owners’ lifetimes, but the titling may affect how the bank calculates each owner’s share when you divide the balance.

What One Owner Can Do Alone

Either co-owner generally has equal legal access to the entire balance, regardless of who put the money in. That means one person can withdraw everything and request that the account be closed without the other owner’s signature or knowledge.¹

Removing one owner while keeping the account open is different. Most banks and most state laws require the person being removed to consent.² A few banks allow one-sided removal, but that’s the exception. When a co-owner won’t cooperate, closing the account and opening a new individual account in your name is usually the simpler route.

Steps to Close and Split the Balance

Once you know what your agreement allows, the process itself is fairly short.

Open a new individual account first, ideally before you touch the joint one, so the bank can move your share directly and you have somewhere to point automatic payments.
Gather what the bank will ask for: government-issued photo ID and Social Security number for each owner involved, plus an account closure or ownership-change form. Some banks require a signed consent form from the owner being removed, and a few ask for it to be notarized.
Visit a branch if you can. In-person requests are usually the fastest because the bank can verify identity and process the change on the spot. Mailed or uploaded forms may take extra days.
Tell the bank what to do with the money: transfer it to a new individual account, split it between two accounts, or issue a cashier’s check. The bank follows the owners’ instructions; it doesn’t decide who gets what.
Ask for written confirmation that the account has been closed or modified, and keep it. If a dispute comes up later about when the change took effect, that letter is your proof.

If you’re keeping the account open with one owner removed, the remaining owner may receive a new debit card and updated account documents. The account number sometimes changes too, so confirm that before you hand out new payment details.

Redirect Deposits, Auto-Pays, and Outstanding Checks

Before you finalize anything, list every recurring payment and direct deposit tied to the joint account. Direct deposits (paycheck, Social Security, tax refunds) run through the Automated Clearing House network, and updating the routing usually takes one to two pay cycles.⁴ Give your employer or benefits agency the new account details well in advance so nothing lands in a closed account.

Do the same for automatic bill payments: utilities, insurance premiums, loan payments, subscriptions. Missing one can trigger late fees or service cancellations. Once you think everything is redirected, consider leaving the joint account open with a small buffer for about 30 days to catch strays.

Outstanding checks are another common problem. Closing the account will cause any check that hasn’t cleared yet to bounce. The payee’s bank may charge them a returned-item fee, and you still owe the payee the money.⁵ Wait for outstanding checks to clear, or contact the payees to arrange another form of payment before you close.

You’re Both on the Hook Until the Account Is Closed

Both co-owners are individually responsible for everything that happens in the account, including overdrafts, fees, and negative balances, regardless of who caused it. If your co-owner overdraws the account or racks up fees after you’ve mentally moved on but before the closure is official, the bank can pursue either of you for the full amount.

This matters most during the transition. If you leave the joint account open while you redirect payments, watch the balance. An unexpected charge from a service linked to your co-owner could push it negative, and you’d share legal responsibility for the debt. Closing promptly, or at least stripping out automatic payment authorizations you don’t control, reduces that risk.

How the Split Affects FDIC Insurance

The FDIC insures joint accounts separately from individual accounts. Each co-owner of a qualifying joint account is insured up to $250,000 for their combined interests in all joint accounts at the same bank.⁶ A two-person joint account is therefore covered up to $500,000 total.

When you split the account into two individual accounts, each new account falls under single-ownership coverage, still $250,000 per depositor. For most people, total coverage doesn’t change. If you already have other individual accounts at the same bank, though, balances are combined for insurance purposes.⁷ Someone who already holds $200,000 in a personal savings account and then adds $150,000 from a former joint account at the same bank would have $350,000 in single-ownership accounts, exceeding the limit by $100,000. Spreading large balances across multiple banks keeps everything within coverage.

Tax Consequences of Dividing the Money

Interest Income

Banks report interest earned on a joint account to the IRS on a single Form 1099-INT, issued under whichever owner’s Social Security number is listed first. If the 1099-INT comes in your name but part of that interest actually belongs to your co-owner, the IRS treats you as a “nominee” for the other person’s share.⁸ You report the full amount on your return, then subtract the portion belonging to your co-owner by filing a nominee Form 1099-INT. Spouses filing jointly don’t need to bother with this; the nominee rules apply only when the interest belongs to someone other than your spouse.⁹

Gift Tax

For married couples, dividing a joint balance is generally not a taxable event, because transfers between spouses are exempt from gift tax. Unmarried co-owners are treated differently. If one person funded most of the account and the other walks away with a share above $19,000 (the annual gift tax exclusion for 2026), the person who funded the account may need to file a gift tax return on IRS Form 709.¹⁰ Filing doesn’t necessarily mean owing gift tax, since a large lifetime exemption applies, but the transfer still has to be reported. For gifts to a spouse who isn’t a U.S. citizen, the annual exclusion is $194,000 for 2026.¹¹

If a Divorce Is Involved, Stop and Get Advice

Separating a joint account during a divorce carries extra legal risk. Several states impose automatic temporary restraining orders (sometimes called ATROs) the moment a divorce petition is filed. These freeze the financial status quo and generally prohibit either spouse from closing joint accounts, draining balances, or moving marital assets without agreement or court permission. Even in states without automatic orders, a judge can issue one on request.

Withdrawing a large sum right before or during a divorce can backfire. Courts often view draining a joint account as an attempt to hide marital assets, and a judge may order the money returned, reduce your share of other assets to compensate, or hold you in contempt. If you genuinely need funds for living expenses during a separation, withdraw only what you reasonably need and keep detailed records of how you spend it. Once proceedings are underway or clearly coming, talk to a family law attorney before touching the account.

If the Account Is a CD

Certificates of deposit work differently from checking and savings. Closing a CD before its maturity date triggers an early withdrawal penalty. Federal law sets a minimum penalty of seven days’ simple interest for withdrawals within the first six days after the deposit, but there is no federal cap on the maximum penalty a bank can charge.¹² Banks set their own schedules, and longer-term CDs typically carry heavier penalties, often several months of interest. Check the specific terms in your CD agreement. Sometimes waiting until the CD matures and splitting the proceeds then is cheaper than breaking it.
