Does Bank Account Location Affect Domicile

I had a client, Emily, call me in a panic last month. Her mother had passed away owning a modest home in Palm Springs and a bank account with $85,000 in it. Emily had recently moved to Nevada, opened a bank account there, and was actively managing her mother’s affairs remotely. She’d heard from a well-meaning acquaintance that simply having a bank account in Nevada would be enough to avoid California probate, potentially saving her tens of thousands of dollars in legal fees. That’s simply not how it works, and she was on the verge of making a potentially disastrous mistake.

The location of a bank account is one factor among many that the California Franchise Tax Board (FTB) considers when determining domicile. It’s far from a definitive indicator. Residency, and thus domicile for estate planning purposes, is a deeply fact-dependent question. We spend a lot of time with clients teasing out these facts because a misstep can lead to significant tax implications. As a CPA as well as an Estate Planning Attorney with over 35 years of experience, I’m uniquely positioned to help clients navigate these complexities – and to anticipate pitfalls most attorneys miss.

For example, the value of Emily’s mother’s home was well within the limits for the new Petition for Succession under AB 2016 (Probate Code § 13151), which allows a streamlined process for smaller estates. However, the total value of all of her mother’s assets – not just the home – needed to be considered. If those assets exceeded $208,850, even with the home qualifying for the Petition, the standard probate process would apply. It’s a common misconception that focusing solely on the real estate value is enough. And, crucially, simply having a bank account elsewhere doesn’t shield assets from California jurisdiction.

What is the Closest Connection Test?

The FTB uses what’s called the “Closest Connection” test, evaluating nineteen different factors to ascertain where your primary domicile truly lies. These factors aren’t weighted equally, and the specifics of your situation are paramount. Simply opening an account in another state doesn’t override factors like where you’ve maintained your driver’s license, where you receive mail, the location of your doctors and dentists, and where you’re registered to vote.

How Will the FTB Verify Residency?

Don’t underestimate the thoroughness of an FTB audit. They will scrutinize your life through Form 4600 (Residency Questionnaire). They’ll ask about seemingly minor details, like the location of your dentist, where your pets are registered, and even where you keep your safe deposit boxes. They are looking for a consistent pattern of connection to a particular state. Spending less than 183 days in California does not automatically terminate residency; the FTB uses the ‘Closest Connection’ test (evaluating 19 factors like your primary doctor and social ties) to determine domicile.

What About the Impact on Capital Gains?

Domicile is critically important when it comes to capital gains taxes. California taxes capital gains on assets sold by residents, even if the asset itself is located outside the state. Proper estate planning can leverage the step-up in basis upon death to minimize these taxes. This is where my dual expertise as an attorney and CPA is invaluable. I can help clients structure their estates to maximize the tax benefits available, taking into account the complex interplay of federal and state laws. Moving assets around without a clear understanding of the tax consequences can result in unexpected and substantial liabilities.

• Bank Account Location: One factor among many.
• Closest Connection Test: The FTB’s primary method for determining residency.
• Form 4600: Used by the FTB to verify residency details.

How do probate courts in California evaluate intent when a will is challenged?

In California, a last will and testament operates within a probate system that emphasizes intent, clarity, and procedural compliance. When properly drafted, a will does more than distribute property—it creates legally enforceable instructions that guide courts, fiduciaries, and beneficiaries through administration with fewer disputes and less uncertainty.

• Authority: Define executor duties clearly.
• Guardians: Establish guardian nominations for minors.
• Jurisdiction: Confirm residency rules.

For California residents, understanding how intent, authority, and compliance interact is one of the most effective ways to protect family harmony and estate integrity. A will that anticipates probate scrutiny is far more likely to be honored as written and far less likely to become the source of unnecessary conflict.

Controlling Legal Standards for Establishing Domicile and Residency

• Residency Guidelines: FTB Pub 1031 (Guidelines for Determining Resident Status)
  This is the primary resource for the “Closest Connection” test. In 2026, it details how the FTB evaluates 19 factors—including the location of your healthcare providers and social ties—to determine if your presence in the state is “permanent” or merely “transitory.”
• Voter Registration: California Secretary of State – Voter Registration
  Updating your voting address is a critical indicator of intent. For the June 2, 2026, Primary Election, the deadline to register online is May 18, 2026. This serves as a public declaration of your primary home.
• Federal Estate Tax: IRS Estate Tax Overview
  While domicile determines state tax, this resource outlines federal guidelines. It reflects the 2026 OBBBA update, which permanently set the federal estate tax exemption at $15 million per person ($30 million for couples), indexed for inflation.
• Proof of Residency: California DMV – REAL ID Checklist
  Since the federal enforcement deadline passed in 2025, a REAL ID is mandatory for domestic flights. This page lists the specific residency documents (e.g., utility bills, tax returns) that the state accepts as proof of a permanent California address.
