Does Where My Kids Go to School Prove Domicile

Lillian just received a notice from the California Franchise Tax Board (FTB) asserting she’s a California resident, despite having moved to Nevada three years ago. Her biggest mistake? She continued to claim the children’s tuition expense credit on her California tax return, coupled with the fact that her kids remained enrolled in their California school district. She thought simply enrolling them in a Nevada school would be enough. It wasn’t. Now she faces years of amended returns, penalties, and a potential audit. The cost? Easily $20,000 or more in back taxes and professional fees.

Establishing domicile—your true, fixed, and permanent home—is often more complex than simply changing your mailing address. While many assume that where their children attend school is a definitive indicator of residency, the reality is far more nuanced, particularly when navigating the FTB’s rigorous “Closest Connection” test. The FTB isn’t interested in what appears to be true; they want proof of where your life is actually centered.

What Factors Does the FTB Consider When Determining Domicile?

The FTB’s analysis goes beyond just school enrollment. They look at a comprehensive set of 19 factors to determine where your primary home truly resides. These include your driver’s license, vehicle registration, voter registration, bank accounts, location of your primary physicians, and even where you own personal property. School enrollment is one piece of the puzzle, but it’s rarely, if ever, conclusive on its own. A child attending school in California while the parents reside elsewhere presents a complex situation that requires careful documentation and planning.

Can School Enrollment Override Other Residency Indicators?

Potentially, yes, but it’s a difficult hurdle. If all other indicators point to a new domicile, the FTB may give weight to the fact that the children remain in a California school. However, this requires a compelling explanation – perhaps a temporary situation due to a specific educational need, a court order, or a grandparent assisting with childcare. Simply maintaining the status quo, while establishing a new life elsewhere, won’t suffice. Continued claims for California tax benefits, such as the dependent exemption or the tuition credit Lillian was claiming, significantly undermine any argument that her primary home is no longer in California.

How Does This Impact Estate Planning and Taxes?

Domicile is critical for both estate planning and income tax purposes. For estate tax, your domicile determines where your estate will be subject to probate and potentially subject to estate tax (though 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). For income tax, your domicile determines which state has the right to tax your income. Moving to a state with no income tax, like Nevada, offers significant savings, but you must definitively sever ties with California to reap those benefits. Remember, 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 Grandparenting Situations?

We frequently advise clients who’ve moved but have grandchildren still attending school in California. In these scenarios, establishing a clear and documented pattern of non-California connections is paramount. This includes formally changing your driver’s license and vehicle registration, opening bank accounts in your new state, and actively participating in community life outside of California. Furthermore, 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. We guide clients through a detailed checklist to ensure they’ve addressed all potential areas of scrutiny.

The CPA Advantage: Beyond Just Tax Returns

As an Estate Planning Attorney and CPA with over 35 years of experience, I bring a unique perspective to these matters. I don’t just prepare tax returns; I understand the intricate interplay between estate planning, domicile, and tax residency. This allows me to proactively structure your affairs to minimize tax liabilities and ensure your estate plan reflects your true intentions. Importantly, a CPA’s knowledge of valuation and the step-up in basis can be instrumental when transferring assets, especially real property. For example, the difference between the Small Estate Affidavit (strictly for real property <$69,625, used for timeshares/vacant land) and AB 2016 is crucial. 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). It’s vital to understand that this is a "Petition" that requires a Judge's Order, not an "Affidavit." However, to qualify, the decedent's other non-real estate assets (cash, stocks, etc.) must typically remain below the separate $208,850 Small Estate limit.

How do California courts decide whether a will reflects true intent or creates ambiguity?

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.

When a will is drafted with California probate review in mind, it becomes a stabilizing roadmap rather than a source of conflict. Clear intent, proper authority, and compliant execution protect both families and estates.
