Joint accounts

A joint deposit account is one held by two or more persons. In the United States, the legal substance of "joint" depends on the form chosen at account opening: joint tenancy with right of survivorship, tenancy in common, or a convenience account (sometimes called an agency or signature-only account). The forms differ in who owns the funds during the lifetimes of the holders, what happens at the death of one holder, and the consequences for taxes, creditor reach, and divorce-property division. They also differ — modestly — in their FDIC-insurance treatment.

This article describes each form, the practical implications of choosing one over another, and the situations in which the differences matter. For the related question of accounts after a death, see accounts after a death; for the insurance treatment in detail, see FDIC deposit insurance.

Joint tenancy with right of survivorship (JTWROS)

The most common form of joint account in U.S. retail banking is joint tenancy with right of survivorship. Each co-owner has equal access to the funds and equal authority to withdraw them; each is treated as owning the entire account during life. On the death of one tenant, the surviving tenant(s) become the sole owner(s) of the entire account by operation of law — the account does not pass through probate. The deceased tenant's interest "evaporates" at death, and the survivor takes the whole.

The right-of-survivorship feature is the principal reason couples and family members choose JTWROS: it provides immediate access to funds for the survivor without the delay of probate. It also has consequences that depositors should understand:

• During life, either tenant can withdraw any or all of the funds without the other's consent. There is no "my half" of a JTWROS account.
• Each tenant's creditors can typically reach the entire account through garnishment or levy, subject to state-law exemptions and protections. The fact that one tenant did not incur the debt does not protect the funds from the other tenant's creditors.
• The funds pass to the survivor on death regardless of the deceased tenant's will. If the deceased's will leaves the account to someone else, the will is overridden by the survivorship feature.
• For tax purposes, the entire account is included in the deceased tenant's estate for estate-tax computation, with adjustments under state law and federal rules for the surviving spouse.

FDIC insurance for JTWROS treats each co-owner's interest as equal absent contrary documentation; with two co-owners, the account is insured up to $500,000 ($250,000 per co-owner); with three, $750,000; with four, $1,000,000. The aggregate insurance across all JTWROS accounts the same individual holds at the same bank is the per-owner limit times the number of co-owners, with the individual's share capped at $250,000 across all such accounts.

Tenancy in common

A tenancy in common (TIC) account is held by two or more persons in defined fractional shares (often equal, but not necessarily). Unlike JTWROS, on the death of one tenant, that tenant's share passes to the tenant's estate — to the heirs under the will or under intestacy law — rather than to the surviving tenant(s). The account does not have automatic survivorship.

TIC is the default joint-account form in some states; in others (notably community-property states), the default for spouses is community-property treatment, which has its own implications. The form is most often used by business partners, by adult siblings who want to maintain separate-property treatment, or by couples who specifically want each spouse's share to pass through their own estate rather than to the survivor.

Tenants-in-common funds are subject to the same during-life access rules as JTWROS — typically either tenant can withdraw — but the at-death treatment is fundamentally different. A TIC account is in practice less common in retail banking than JTWROS but is offered by most institutions on request.

Convenience accounts

A convenience account (sometimes called an agency account or signature-only account) is a single-owner account on which a second person has signature authority but no ownership interest. The convenience signer can write checks, make withdrawals, and otherwise transact on the account during the owner's life, but the funds belong entirely to the owner; at the owner's death, the funds pass through the owner's estate, not to the convenience signer.

The convenience form is the right choice in two specific situations: when an elderly account-holder wants a trusted adult child to help manage the account without giving them an ownership interest, and when a businesswoman wants an assistant to be able to write checks against an account that remains the principal's property. The distinction from JTWROS matters most at death — the convenience signer is not entitled to the funds — but also during life: the convenience signer's creditors cannot reach the funds, because the convenience signer has no ownership interest.

Not all banks offer a true convenience account; some require account-holders to use JTWROS or to grant a separate power of attorney to achieve the same practical result. When opening any joint-style account, the depositor should ask explicitly which legal form the account agreement creates; the bank's intake forms often default to JTWROS without making the choice visible.

Divorce, creditors, and tax

Three further consequences of joint-account form matter in specific contexts.

Divorce. A joint account opened during marriage is typically treated as marital property in divorce, regardless of the legal joint form chosen. The form may, however, affect the prima facie ownership presumption: a JTWROS account is presumed jointly owned 50/50, while a TIC account with documented unequal shares is presumed owned in those proportions. Tracing of separate-property contributions (an inheritance deposited into a joint account, for example) is a separate matter governed by state law.

Creditors. A joint account exposes each co-owner's funds to the creditors of every other co-owner, subject to state-law protections. Some states give partial protection to the non-debtor co-owner's funds in a JTWROS account; others do not. The garnishment treatment is governed by the same federal benefit-protection rule (31 CFR Part 212) discussed in garnishment and account levies, with the protected federal-benefit lookback applying to the named recipient's directly-deposited benefits regardless of joint-account form.

Tax. Interest income on a joint account is reportable to the IRS under the Social Security number of the "primary" owner (typically the first-named account holder), regardless of who contributed the principal. The actual tax allocation between co-owners is determined by ownership shares; co-owners who report differently from the 1099 issued may need to use a nominee-allocation procedure. This is a tax-planning matter on which a qualified tax professional should be consulted.

Closing a joint account

Either co-owner of a typical joint account can ordinarily close the account unilaterally, though many banks require either consent or notification of the other co-owner. The bank's account agreement specifies the procedure. For a JTWROS account being closed because of the death of a co-owner, the survivor presents a certified death certificate, the account is retitled (or closed and re-opened in the survivor's name), and the funds remain accessible without probate.

Limits and uncertainty

The legal forms of joint ownership are established by state law and have been stable for many decades. The FDIC-insurance treatment of joint accounts is set by federal regulation (12 CFR §330.9) and was last meaningfully revised in 2024 in the context of revocable-trust account coverage. The interaction between joint-account form and creditor exposure varies by state and is more contested than the basic form definitions; a depositor with substantial balances and creditor concerns should consult a qualified attorney. The bank-account intake process at most institutions does not adequately walk customers through the choice of form; the customer should ask which form they are opening, and verify on the signature card or account-opening confirmation that the chosen form matches the customer's intent.
