His Brokerage Account Says ‘JTWROS’ at the Top. Those Letters Decide Who Gets the Money When He Dies

The title line on many joint brokerage statements says “JTWROS,” and many account owners have never asked what those letters mean. Those letters decide who gets the money when an owner dies, and a will can’t redirect it. When one joint tenant dies, their interest passes to the surviving owners without probate, although its value may still count toward the deceased owner’s estate for federal tax purposes.

JTWROS stands for joint tenants with right of survivorship, though some shorten it to “JT TEN.” It’s a common way to title joint brokerage accounts. These accounts can hold a lot of money, too. Publicly traded stock showed up on 5934 of the 7195 estate tax returns filed in 2024.

Three Account Titles That Send Your Money to Different People

The title at the top of your statement determines who inherits the account. Here are the three you’ll see most often:

• Joint tenants with right of survivorship. When one owner dies, the other automatically gets the whole account, and it skips probate (the court process that settles an estate).
• Tenants in common. Each owner holds a share. When an owner dies, that share goes to their own heirs through their will or estate.
• Individual with a transfer-on-death beneficiary. You own the account by yourself, and the person you name inherits it when you die. It functions like a bank account that goes directly to a named beneficiary, which we’ve covered separately.

Community property states also tend to offer their own account forms for married couples. Ask your brokerage which ones it has for your state.

What the Tax Code Says About Joint Accounts

The title also affects how much tax a survivor owes. Your “basis” is generally what you paid for an investment. When you sell, you pay tax on the gain above that number. Under 26 U.S.C. § 1014(a)(1), inherited property usually gets a new basis equal to its fair market value on the date of death. That’s the step-up, and it can wipe out years of gains.

How much of a shared account gets that step-up depends on who the other owner is.

• Spouses: 26 U.S.C. § 2040(b) puts half of a spousal JTWROS interest in the estate of whoever dies first, as long as the two spouses are the only joint owners. Per IRS Publication 551, it doesn’t matter how much each spouse contributed. Only the half that belonged to the spouse who died gets stepped up. In IRS Publication 523’s example, a jointly owned home with a $50,000 basis and a $100,000 value ends up with a new basis of $75,000.
• Non-spouses: 26 U.S.C. § 2040(a) counts the full value in the estate of the owner who died, minus whatever part the survivor can prove they paid for. In Publication 551’s example, a survivor who contributed no part of the purchase price got a basis equal to the full market value.
• Community property: In Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin, the whole property generally gets a new basis when a spouse dies, including the surviving spouse’s half. That treatment has one condition: at least half the value of the community property interest must be includible in the decedent’s gross estate.

A smaller step-up leaves more built-in gain behind, and the survivor pays tax on it when they sell.

How to Check and Fix Your Account Title

1. Log in and find the exact registration on each account. Look for abbreviations like JTWROS, JT TEN, TEN COM, or TOD.
2. Check that the title matches what you actually want. If your share should go to children from an earlier marriage, a JTWROS title passes it to your co-owner instead.
3. If you’re married and live in a community property state, ask whether your brokerage offers community property ownership, since that can step up both halves.
4. If you are the sole account holder, add a transfer-on-death beneficiary so it skips probate.
5. On a shared account with someone who isn’t your spouse, keep records of who contributed what. Under § 2040(a), the survivor may have to show what they contributed.

Adding a Grown Child Can Backfire

Parents often add an adult child to an account so the child can help pay bills. Joint owners are legal owners, though. That means the account may be subject to creditor attachment, divorce proceedings, bankruptcy, or other similar liability issues of the other owners. That includes your child’s.

It can also cut out your other kids. Survivorship sends the whole account to the child named on the title, regardless of what your will says about splitting things evenly. If you just need help paying bills, a convenience signer might be a better fit. We’ve covered how that works separately.
