What Are the Community Property States?
Learn about the community property states and how laws in these states can impact your estate planning strategies.
In community property states, most assets and debts acquired during a marriage belong equally to both spouses. That simple idea has big ripple effects on titling, taxes, and how everything transfers after someone’s passing.
How Married Property Shapes Estate Planning
Title choices. Some states offer community property with right of survivorship, a deed form that lets the surviving spouse take full title without probate when one spouse passes. It pairs the equal-ownership concept with an automatic transfer.
Tax basis after a spouse’s passing. A headline advantage in community property jurisdictions is a potential full step-up in tax basis on community assets, not just on the decedent’s half. That can lower capital gains if the survivor later sells appreciated assets like a home or brokerage holdings.
Labeling matters. Correctly labeling assets—community vs. separate—helps keep intentions clear, speeds administration, and reduces conflict. Clean records (titles, beneficiary designations, and a written inventory) make the difference when distributing assets.
Beneficiaries and accounts. Some institutions and plans require spousal consent before changing beneficiaries in community property jurisdictions. Double-check retirement plans, insurance policies, and payable-on-death designations.
At its core, community property means earnings during marriage—and items bought with those earnings—are jointly owned. By contrast, assets owned before marriage, plus gifts and inheritances to one spouse, usually remain separate. Debts work similarly: many obligations taken on during marriage are shared. Rules vary by state, but that’s the broad frame.
Nine states use community property as the default marital property system (as opposed to equitable property). They are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin.
Several states also offer opt-in community property—typically by creating a special trust or agreement. These include Alaska, Florida, Kentucky, South Dakota, and Tennessee. Opt-in frameworks can give couples certain community property benefits even in otherwise non-community jurisdictions.
Examples
1) The family home.
Jordan and Sam live in Nevada and buy a house during their marriage. It’s community property. When Jordan passes, Sam records the appropriate documents and—if the deed is titled as community property with right of survivorship—receives full title without probate. Later, if Sam sells, the home’s tax basis may be stepped up for both halves, reducing taxable gain. (Documentation still matters: keep closing statements, improvements receipts, and the deed.)
2) The inherited cabin.
Patty, in Texas, inherits a small lake cabin during marriage. She keeps title in her name and pays expenses from a separate account. Properly kept separate, the cabin remains Patty’s separate property. If community funds pay the mortgage or major improvements, the community may gain a reimbursement claim—another reason to track records.
3) The brokerage account.
Alex and Riley, in Washington, fund a taxable investment account with salary during marriage. It’s community property. Alex later names a sibling as account beneficiary without telling Riley. Depending on the custodian’s rules and state law, spousal consent may be required or the designation could be limited by community rights. Always align beneficiary forms with the property system.
Takeaways for Couples in Community Property States
- Title major assets intentionally (and consider survivorship community property where available).
- Keep a running inventory that labels assets as community or separate.
- Align beneficiary designations with community rules and your written plan.
- Save proof for separate assets—inheritance letters, prior-marriage deeds, and account statements.
Understanding community property states helps you organize ownership, simplify transfers, and potentially unlock meaningful tax advantages for a surviving spouse. With clear titles, tidy records, and beneficiary forms that match your goals, your plan can run smoothly when loved ones need it most.
