For a married couple deciding how to title a home, the practical difference between joint tenants with right of survivorship and community property comes down to taxes: community property gives the surviving spouse a full step-up in basis on the entire property, while joint tenancy only steps up the deceased owner’s half. That one distinction can mean tens of thousands of dollars in capital gains tax when the surviving spouse sells. Joint tenancy’s own advantage is that it works for any two or more co-owners and skips probate automatically. In several community property states, a hybrid form lets married couples get both benefits at once.
What Each Form Actually Is
Joint tenancy with right of survivorship is a co-ownership arrangement where two or more people hold equal, undivided interests in the same property. Any combination of people can use it: spouses, siblings, business partners, friends. When one owner dies, that owner’s share passes automatically to the survivors without probate. The deed has to say so explicitly; without survivorship language, most states default to tenancy in common, which has no automatic transfer.
Community property is a marital property system, available only to married couples and, in some states, registered domestic partners. Almost everything either spouse earns or acquires during the marriage belongs equally to both, regardless of whose name is on the title or paycheck. Nine states use it as their default: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin.1CCH AnswerConnect.

Assets owned before the marriage, plus gifts and inheritances received during it, stay separate.
Shares are rigid in both systems. Joint tenancy requires equal shares among all owners. Community property is always a 50/50 split between spouses, no matter who contributed what.
The Step-Up in Basis: The Tax Reason This Choice Matters
The step-up in basis resets a property’s tax basis from its original cost to its fair market value on the date of death. A higher basis means less taxable gain when the property is sold later. This is where the two ownership forms diverge most sharply.
Joint Tenancy Steps Up Only Half
When a joint tenant dies, only the deceased owner’s share gets a stepped-up basis. The surviving owner’s original basis on their own share stays put. For spouses holding property as joint tenants, half the property is included in the deceased spouse’s gross estate for federal estate tax purposes.2Office of the Law Revision Counsel. 26 U.S. Code 2040 – Joint Interests
A couple buys a home for $200,000 and holds it as joint tenants. When one spouse dies, the home is worth $800,000. The surviving spouse’s new basis is $500,000: the original $100,000 on their own half plus a stepped-up $400,000 on the deceased spouse’s half. A sale at $800,000 produces a $300,000 taxable gain before any exclusions.
Community Property Steps Up Both Halves
Under federal tax law, the surviving spouse’s half of community property also gets a step-up in basis to fair market value at the date of death, not just the deceased spouse’s half.3Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent Using the same numbers, the surviving spouse’s new basis for the whole home becomes $800,000. A sale at $800,000 produces no taxable gain at all.
On $600,000 of appreciation, the difference between a $300,000 gain and no gain translates to real money. At current long-term capital gains rates, a surviving spouse in a moderate tax bracket could owe $45,000 or more under joint tenancy that they would owe nothing on under community property. For couples who own highly appreciated real estate or investments, this is usually the deciding factor.
What Happens When an Owner Dies
Joint tenancy transfers the property automatically. The moment one owner dies, the survivors own the whole thing by operation of law. The surviving owner typically records an affidavit of survivorship with the death certificate at the county recorder’s office. Days, not months, and very little cost. The catch is that the will doesn’t control. If a joint tenant’s will leaves their entire estate to their children, the jointly held property still goes to the surviving tenant, because survivorship overrides the will.
Standard community property works differently. It does not include an automatic right of survivorship. When one spouse dies, their half becomes part of their estate and passes under their will, or under state intestacy law if there is no will. In most community property states, intestacy sends the deceased spouse’s share to the surviving spouse anyway, but the transfer usually has to go through probate: court supervision, months of delay, filing fees, attorney time, and a public record.
The Hybrid: Community Property With Right of Survivorship
Several community property states let married couples combine the two advantages. Texas, for example, allows spouses to sign a survivorship agreement that keeps the community property character of the asset while adding automatic transfer at death. The transfer is not treated as a testamentary disposition, so it bypasses probate.
The result is the full double step-up in basis plus probate avoidance in a single arrangement. Not all nine community property states offer this option, and the formal requirements vary. Couples who want it should confirm their state recognizes it and follow the state’s specific rules for creating it.
Control: Who Can Act Alone
These forms handle unilateral decisions in opposite ways, and that matters when co-owners disagree.
A joint tenant can sell or transfer their own share without asking the others. The transfer breaks the joint tenancy for that share, converting it into a tenancy in common with no survivorship right. The other owners keep their joint tenancy among themselves, but a stranger now holds the departing owner’s share. There is no legal basis to stop it.
Community property real estate works the opposite way. In most community property states, neither spouse can sell or mortgage the family home without the other spouse’s written consent. That protects both spouses from a unilateral sale, but it also means either spouse can block one. For everyday management of other community assets like bank accounts, either spouse generally has independent authority.
Creditor Exposure
How each form handles one owner’s debts gets less attention than it deserves.
In a joint tenancy, a creditor’s lien against one owner’s interest generally does not survive that owner’s death. Because survivorship operates at the instant of death, the deceased owner’s interest is extinguished rather than transferred, and the surviving owner takes free of the lien. Courts have applied this even to federal tax liens. During the debtor’s lifetime, though, a creditor can force a partition or sale of that owner’s share, which severs the joint tenancy.
Community property states generally treat debts incurred during the marriage as community obligations, regardless of which spouse took them on. Creditors can reach community assets to satisfy one spouse’s debt even if the other spouse never signed anything. If one spouse accumulates business debts, the other spouse’s wages and shared assets are exposed. For clearly separate debts, like child support from a prior relationship, creditor access to community property is more limited but not fully blocked.
How Fragile Is the Survivorship Right?
Joint tenancy survivorship is less durable than most co-owners assume. Any joint tenant can destroy the survivorship right unilaterally by transferring their interest to someone else, or even to themselves under a different form of title. The transfer converts that share to a tenancy in common, and survivorship no longer applies to it.4Legal Information Institute. Right of Survivorship A joint tenant can also petition a court for partition, which is an absolute right the other owners cannot block. One owner’s decision to sell, gift, or mortgage can eliminate the automatic transfer the other owners were counting on.
Community property is more stable in this respect because, for real estate at least, one spouse cannot act alone to change the title or encumber the property.
A Few Boundaries Worth Knowing
Adding a Non-Spouse Can Trigger Gift Tax
Adding someone to a deed as a joint tenant can create federal gift tax consequences. If you add a non-spouse to the title of property you own, you have made a gift equal to the value of the ownership share they receive. In 2026, the annual gift tax exclusion is $19,000 per recipient.5Internal Revenue Service. Frequently Asked Questions on Gift Taxes Adding an adult child to the deed of a $400,000 home is a $200,000 gift, which far exceeds the exclusion and requires a gift tax return applying the excess against the lifetime exemption. Transfers between spouses are generally exempt, so this does not arise when a spouse is added. Married couples giving jointly can exclude up to $38,000 per recipient in 2026.
Moving Between States
Moving from a community property state to a common-law state does not automatically convert your community property into something else. Many common-law states have adopted some version of the Uniform Disposition of Community Property Rights at Death Act, which preserves the community property character of what you brought with you. Moving the other direction, from a common-law state to a community property state, generally does not retroactively convert existing assets into community property. Only assets acquired after you establish residence are presumed community property. Some states apply “quasi-community property” rules at death or divorce, and those rules vary.
Tenancy by the Entirety
Married couples in common-law states sometimes have a third option: tenancy by the entirety. It carries the survivorship feature of joint tenancy, but neither spouse can unilaterally sell, mortgage, or transfer their interest. Both must agree. Many states that recognize it also give it stronger creditor protection, because a creditor of only one spouse generally cannot force a sale of entirety property. Not every state offers it, and some that do limit it to real property. Couples who want the probate-avoidance of joint tenancy without the risk that one spouse could sever it should ask whether their state recognizes this form.
