Does Bank Account Location Affect Domicile

I recently had a client, David, discover a crucial error in his estate plan just weeks after his mother’s passing. She’d meticulously prepared a codicil to her trust, attempting to shift assets, but it was improperly executed – a single missed signature rendered it invalid. The resulting probate costs, plus the legal fees to untangle the mess, exceeded $45,000. It’s a painful lesson illustrating how even seemingly small details can have massive financial repercussions. And often, clients ask about seemingly minor details, like where they keep their money, thinking it will solve complex domicile issues.

As an Estate Planning Attorney and CPA with over 35 years of experience, I’ve seen countless scenarios where clients misinterpret the concept of domicile. It’s far more nuanced than simply having a bank account in a particular state. While your banking relationships are considered as part of the overall picture, they’re rarely, if ever, determinative of your legal residence for estate tax or probate purposes. The Franchise Tax Board (FTB) looks at the totality of your connections to a state – not just where you deposit your checks.

What Exactly Is Domicile, and Why Does It Matter?

Domicile isn’t just where you currently live; it’s your true, fixed, and permanent home – the place you intend to return to, even if you’re temporarily elsewhere. Establishing domicile correctly is critical for several reasons. It dictates which state’s laws govern the distribution of your assets, and, crucially, impacts potential estate taxes. California is a high-tax state, and incorrect domicile designation can lead to significant tax liabilities. The CPA perspective is particularly helpful here. We understand the implications of step-up in basis, capital gains calculations, and the proper valuation of assets – all heavily influenced by your domicile.

How Does the FTB Determine Your Domicile?

The FTB doesn’t rely on a simple checklist. 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. They’ll examine everything from where you’re registered to vote to the location of your driver’s license, where your children attend school, and the frequency and duration of your absences. They’ll even scrutinize seemingly personal details. Auditors will use Form 4600 (Residency Questionnaire) to scrutinize your life, including the location of your dentist, the registration of your pets, and where you keep your safe deposit boxes.

Bank Accounts, Real Estate, and the Impact of AB 2016

So, where do bank accounts fit in? They are evidence, but not conclusive proof. Having a bank account in Florida doesn’t magically make you a Florida resident. The FTB will see through that attempt to avoid California taxes if all other indicators point to California as your true domicile. However, bank account location becomes especially critical when coupled with other factors and the complexities of transferring assets. If you own a home in California, understand the rules surrounding real estate transfers. For deaths on or after April 1, 2025, a primary residence valued up to $750,000 qualifies for a ‘Petition for Succession’ under AB 2016 (Probate Code § 13151). Remember, this is a Petition that requires a Judge’s Order, NOT an “Affidavit.” Furthermore, to qualify, the decedent’s other non-real estate assets (cash, stocks, etc.) must typically remain below the separate $208,850 Small Estate limit. If the real property is a timeshare or vacant land, the Small Estate Affidavit (<$69,625) is the correct avenue.

Protecting Your Estate: A Holistic Approach

Establishing and maintaining proper domicile requires a holistic approach. It’s not about isolating a single factor like your bank account; it’s about aligning all your connections to a single state. Don’t fall into the trap of thinking a simple move, or a new bank account, is sufficient. It’s essential to document your intent – your ties to the state you claim as your domicile. This includes maintaining a California address, actively participating in community life, and demonstrating a clear intention to remain in the state indefinitely. Furthermore, the 2026 ‘Sunset’ was averted by the One Big Beautiful Bill Act (OBBBA), which permanently increased the Federal Estate Tax Exemption to $15 million per person effective Jan 1, 2026. This gives us more breathing room in planning, but doesn’t negate the need for careful domicile planning.

What makes a California will legally enforceable when it matters most?

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.

To distribute property effectively, you must define what is in the estate, clarify beneficiary roles, and understand how estate liabilities impact the final distribution.

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.
