The Hidden Costs of Moving to a Low‑Tax State

When most people consider leaving a high-tax state, they figure out the savings this way:  annual income multiplied by the tax rate difference between states. The number that comes out is usually significant. It is also incomplete.

We are not saying the tax savings aren’t real, as they certainly can be. For clients with very high incomes, the annual savings from a well-executed domicile change can be material — meaningfully material. The clients who make good geography decisions are the ones who count everything, yet most who model this decision are only counting one thing.

Let’s talk about what they’re not counting.

Why most tax relocation models are incomplete

If you are deep in your career or recently retired, start with your professional network. If you have spent twenty years building a career in Seattle, San Francisco, or New York, you have a web of relationships — colleagues, clients, investors, board connections, informal referral networks — that is anchored in that geography. That web has value. It generates introductions, opportunities, and information that you may not even consciously notice because it arrives so naturally. It took decades to build and may not offer the same benefits elsewhere.

This dynamic is very acute for founders. A founder who built a company in the Seattle tech ecosystem has relationships with investors, talent networks, and peers that are specific to that place. Moving to Nevada doesn’t eliminate those relationships, but it changes their texture in ways that are difficult to model and easy to underestimate.

What you’re not counting: the non-financial costs

If you’re considering a move around the time of a liquidity event — or shortly before one — the stakes are higher still. The decision about where you’re domiciled at the moment of a transaction is not just a geography question. It’s a layered question that can have implications at the time of the transaction and into the future. Tax considerations associated with a significant exit can be complex and may extend beyond annual rate differences. The potential impact of domicile depends on individual facts and circumstances.

Social capital and community infrastructure

Social capital is another consideration – the neighborhood you know, the school you attended, your place of worship, the local philanthropic relationships you’ve built over years. The community infrastructure that makes a place feel like home rather than a place you happen to live. This is harder to quantify and easy to discount when you’re looking at a large tax savings number. Looking back after you’ve left, it is rarely easy to discount.

Family proximity and ongoing travel costs

Family proximity is part of the equation that deserves its own line. The compounding value of being near aging parents, or near children, grandchildren, siblings, is not something most financial models capture. Neither is the cost of being further away when something happens. We have had clients who moved to tax-advantaged states and spent the next several years flying back to their former city more often than they expected, eroding a significant portion of the tax saving they had modelled.

Last but not least, specialist relationships built over years — such as hospital systems you trust, care networks calibrated to your specific situation, or professional advisors like attorneys and CPAs who understand your circumstances — are not easily reproduced. For clients who are older or who have ongoing health considerations, this is not a minor variable.

The cost of getting the execution wrong

Even when the financial case is genuinely compelling, the execution of a domicile change is more involved than most people expect — and the cost can be high.

As an example, California in particular is aggressive about auditing former residents. The California Franchise Tax Board has a well-documented history of scrutinizing high-income individuals who claim to have left, looking for evidence that the change was incomplete: days spent in-state, professional ties that remain, family relationships, where estate documents were executed. A domicile change that doesn’t hold up to that scrutiny doesn’t just fail to deliver the tax saving — it creates liability.

A properly executed domicile change—such as updating voter registration, re‑executing estate documents, tracking days spent in each state, and severing certain ties—is typically a multi‑step legal and administrative process. When these steps are undertaken thoughtfully, often with the involvement of tax counsel, they are more likely to support the intended tax treatment. By contrast, changes made quickly or without sufficient planning may introduce additional tax and audit risk.

When state tax relocation does make sense

Sometimes relocation does pencil out.

For a client with continued high income, a genuine desire to be somewhere else, the right life circumstances — no deep local roots, family already spread across geographies, healthcare access not a constraint, a professional network that travels well — the financial case for leaving a high-tax state can be compelling. In our experience, these decisions involve tradeoffs that extend beyond tax considerations alone..

Brighton Jones is not in the business of telling clients to stay or go. Our focus is on helping people consider the full picture, including factors that don’t always show up in tax models.

How to model the complete picture: The Personal CFO approach

CPAs appropriately focus on modeling the tax implications of a move, and that analysis is an important part of the decision. Our role, as a Personal CFO, is to complement that work by helping clients consider broader financial and life factors alongside the tax analysis — including execution complexity, long‑term planning considerations, and how the decision fits into the life they want to be living over time.

The difference shows up in the conversation. A tax-only conversation starts with the rate differential and works backward. A complete conversation starts with the life picture — what you’d be moving toward, what you’d be leaving, what the transition actually costs — and then asks whether the financial case holds when the full ledger is counted. Most of the time, for most clients, the answer is more complicated than the initial number suggested. Sometimes it still points toward leaving, but it’s a different decision when you’ve counted everything.

This is not simply a different way of discussing the same analysis. It reflects a broader scope of conversation — one that looks beyond tax rates alone to how a relocation decision affects the full financial picture. And it is the conversation that determines whether the number on the spreadsheet means what you think it means.

Frequently asked questions

Do I have to pay California taxes if I move to Nevada?

Generally, no — if you properly establish Nevada domicile and your specific facts and circumstances support the change. However, California aggressively audits former residents, looking for evidence that the change was incomplete: days spent in-state, professional ties that remain, family relationships, and where estate documents were executed. A properly executed domicile change requires updated voter registration, re-executed estate documents, day-count tracking, and severance of key ties.

What counts as evidence of domicile for tax purposes?

Tax authorities scrutinize high-income individuals who claim to have changed domicile by examining days spent in each state, professional ties that remain, family relationships, and where key documents were executed. If a claimed domicile change does not hold up under review based on an individual’s specific facts and circumstances, it may not deliver the intended tax outcome and can result in additional tax exposure.

When does moving for tax savings make sense?

Tax‑motivated relocation decisions tend to involve more than tax rates alone. Factors such as income stability, family dynamics, healthcare access, and professional ties can influence how these decisions play out over time.

What mistakes do people make when modeling tax relocation?

Most people calculate the decision as annual income multiplied by the tax rate difference. This misses professional network value, social capital and community infrastructure, family proximity and ongoing travel costs, and specialist relationships built over years. These non-financial costs are harder to quantify and easy to discount when looking at a large tax savings number.
