A joint brokerage account is an investment account owned by two or more people who share the right to buy and sell securities, deposit and withdraw funds, and receive the account’s income. Any single owner can typically place trades or move money on their own, and every transaction binds all owners. The ownership structure you pick at opening — not the fact that the account is “joint” — controls what happens if one owner dies, whether a creditor of one owner can reach the assets, and how the tax reporting works.
How Ownership Structure Shapes the Account
The choice you make on the application is the single most consequential decision. Four structures are common, and they behave very differently at death and under creditor pressure.
Joint Tenants With Rights of Survivorship
Joint tenancy with rights of survivorship (JTWROS) gives each owner an equal share of the entire account. When one owner dies, that share transfers automatically to the surviving owner without probate; the survivor takes control by submitting a death certificate and basic paperwork to the brokerage. Because ownership must be equal, two owners each hold 50%, three each hold roughly 33%, and so on.
Tenants in Common
Tenants in common (TIC) allows unequal shares, such as 70/30. There is no right of survivorship. If one owner dies, that share passes to the deceased owner’s estate under the will or state intestacy law, not to the surviving co-owner. Each owner keeps more independent control over what happens to their portion.
Community Property
Community property is available to married couples in Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. Alaska, South Dakota, and Tennessee let couples opt in through a written agreement. Assets acquired during the marriage are presumed to belong equally to both spouses. If one spouse dies, the survivor keeps their half; the other half passes under the deceased spouse’s will or estate plan.
Tenancy by the Entirety
Tenancy by the entirety is a special form of joint ownership limited to married couples. Not every state recognizes it for brokerage accounts, but where it is available, a creditor of only one spouse generally cannot seize any part of the account. It includes a right of survivorship, and neither spouse can sever it alone.
Who Can Act on the Account
Joint brokerage accounts usually operate so that any single owner can place trades, deposit funds, and make withdrawals independently. One person can buy, sell, rebalance, or wire money out without asking the other. Some firms will impose stricter controls that require both owners’ approval for certain actions if you ask, so check with your brokerage if that matters to you.
Because either owner can act alone, every trade or withdrawal is legally binding on all owners. A losing bet by one owner is a loss for both. Shared authority is the feature and the risk at the same time.
You can also add a Transfer on Death (TOD) designation, which names beneficiaries who receive the account assets after the last surviving owner dies and bypasses probate.1Investor.gov.

Opening and Funding the Account
Every person on the account must provide identification and financial information. For each owner, expect the brokerage to ask for:
- Social Security number or taxpayer identification number
- Government-issued photo ID, such as a driver’s license or passport
- Employer name and address
- Annual income, net worth, and investment experience
- Bank account and routing numbers for a funding source
Some firms also ask about investment objectives, risk tolerance, and time horizon.3U.S. Securities and Exchange Commission. Investor Bulletin: How to Open a Brokerage Account
Most major brokerages let you complete the application online. One owner typically starts, enters the account details, and then the second owner supplies their information and signs electronically. The firm runs an identity check on each applicant under federal anti-money-laundering rules,4eCFR. 31 CFR 1023.220 – Customer Identification Programs for Broker-Dealers which usually takes a few business days.
Once approved, you fund the account by ACH transfer or wire from a linked bank. Vanguard, Fidelity, and Schwab have no minimum deposit to open a joint brokerage account, though individual mutual funds may set their own minimums. Wire fees vary; Schwab charges $25 for outgoing wires, or $15 online, while some firms charge as little as $5.5Charles Schwab. Charles Schwab Pricing Guide for Individual Investors
How Taxes Get Reported
The brokerage reports all account income under one primary Social Security number. Form 1099-B for capital gains and losses, Form 1099-DIV for dividends, and Form 1099-INT for interest all list only the primary account holder as the recipient. Both owners are still legally responsible for tax on their share of the income.
If both owners want to report only their portion, the primary account holder files what the IRS calls a nominee return: issue a new Form 1099 to each co-owner showing their share, submit those forms to the IRS with Form 1096, and note the nominee amounts on Schedule B of your own return.6Internal Revenue Service. General Instructions for Certain Information Returns (2025) Spouses who file a joint tax return don’t need a nominee return, since all the income already appears on one return.
Gift Tax When the Co-Owner Isn’t Your Spouse
Opening a joint brokerage account with a child, sibling, or partner can create gift tax consequences. For an account where either owner can withdraw the full balance, the IRS treats a gift as happening when the non-contributing owner withdraws funds for their own benefit, not when you deposit money. The gift equals whatever that person took out without any obligation to repay.7Internal Revenue Service. Instructions for Form 709 That’s different from jointly held real estate, where the gift may happen when ownership is created.
In 2026, you can give up to $19,000 per recipient per year without triggering any gift tax filing requirement.8Internal Revenue Service. What’s New — Estate and Gift Tax If a non-contributing co-owner withdraws more than that in a year for personal use, the contributing owner should file Form 709. Filing doesn’t necessarily mean owing tax; it reduces your lifetime exemption.
What Happens If the Brokerage Fails
If your brokerage firm becomes insolvent, the Securities Investor Protection Corporation (SIPC) covers your account up to $500,000, including a $250,000 limit on cash. A joint account counts as one “customer” no matter how many people own it, so co-owners share the $500,000 rather than each getting their own.9SIPC. Resources – FAQs
A joint account does qualify as a separate “capacity” from individual accounts. If you and your spouse each have individual accounts and share a joint account at the same firm, the joint account gets its own $500,000 of coverage on top of the $500,000 protecting each individual account.10Investor.gov. Investor Bulletin: SIPC Protection (Part 1: SIPC Basics) SIPC covers firm insolvency only. It does not cover normal investment losses.
Creditor Exposure
A creditor of one owner may be able to reach the account. How much exposure you face depends on the ownership structure and state law.
- Tenants in common: a creditor can generally seize at least the debtor’s ownership share, and in some cases force a sale of the entire account.
- JTWROS: a creditor may reach the debtor’s share. In some states, the non-debtor co-owner can protect their portion by proving they contributed all or most of the funds.
- Tenancy by the entirety: where available, a creditor of only one spouse generally cannot touch any part of the account.
- Community property: depending on state law, a creditor of either spouse may be able to reach all or part of the community property, even assets the non-debtor spouse contributed.
Removing an Owner or Splitting the Account
You can remove a co-owner, but both the remaining and departing owners generally must sign a removal form. The account registration then changes; a two-person joint account becomes an individual account for the remaining owner. Margin and options privileges typically must be reapplied for, and checkwriting has to be re-established. If the co-owner has died, the brokerage will need a death certificate and may need a state inheritance tax waiver.
Moving assets out to give one owner their share can trigger taxable events if investments are sold, so an in-kind transfer of shares often makes more sense than a liquidation.
In a divorce, a joint brokerage account is divided like other marital property. Most states follow equitable distribution, which aims for a fair split rather than a strict 50/50. Community property states generally start from equal division. Courts typically split the shares in kind, let one spouse keep the account and compensate the other with assets of equal value, or liquidate and divide the cash. In-kind transfers between spouses as part of a divorce settlement generally don’t trigger capital gains tax; selling investments can. If a divorce is underway, you can ask the brokerage to freeze the account so neither party can trade or withdraw until the settlement or court order sets the terms.
