The essential points
- A substantive move and the sourcing of sale proceeds are separate questions; resolve both.
- Break headline consideration into cash, contingent payments, equity and compensation before modelling the result.
- Test a revised deal, a delayed closing and a failed transaction; the household and business must remain workable.
A founder considering a move before selling a business often starts with the difference between two state tax rates. The more consequential questions come earlier: when does residence actually change, what exactly is being sold, and what connection does each payment retain to the former state?
These questions deserve separate answers. A credible relocation can coexist with continuing tax exposure. Equally, an attractive destination cannot repair a move that exists mainly on documents. Planning should begin with the life the owner intends to lead and the transaction the buyer intends to complete.
Keep three clocks in view
There is a household clock, a transaction clock and a cash clock. The household establishes a new life over a sequence of real events. The deal progresses through negotiations, contractual commitments and completion. Cash may arrive at closing, remain in escrow, depend on future performance or never be paid at all. A calendar that records only the move date and bank transfer is too thin to explain the result.
The analysis below focuses on U.S. state residence and selected California and New York examples. An international departure adds separate federal, immigration and destination-country questions. A state-residence conclusion cannot answer those questions, and the rules of one state should not be used as a template for every other state.
Exhibit 1 · Parallel timelines, different consequences
Make the move substantive
California evaluates residence through the facts, including the strength of connections and whether an absence is temporary or transitory. Its guidance considers home, family, work, time and other relationships; no single factor determines the outcome. The relevant comparison is between the old life and the new one. California FTB: residency guidance.
New York distinguishes domicile from statutory residence. Establishing a new domicile requires evidence that the former domicile was abandoned and a new one established. A person domiciled elsewhere can still be a resident under the separate rules involving an in-state permanent abode and presence. A new address or voter registration alone does not resolve those tests. New York: residency guidance.
The practical implication is straightforward: document what actually changed. Where will the owner work most weeks? Where will the household live? What use will be made of the former home? How much time will continuing business obligations require in the old state? A move should remain workable after the transaction, when the immediate incentive to maintain a particular narrative has passed.
Break the proceeds into their components
A sale agreement can produce several kinds of income. Purchase price for shares, option compensation, a retention payment, consulting fees, interest and a later earnout may arrive in the same bank account but require different analyses. Create a proceeds schedule that separates them before relying on a projected tax result.
California's general rule sources gains from investment stocks and bonds to residence at sale, with separate treatment where trading is a business. That rule should not be treated as a universal assurance about every business exit or every state. The legal asset sold and the applicable state rules must match the analysis. California FTB: sale of stocks and bonds.
Equity compensation requires its own work. California's guidance allocates certain option compensation by the services performed in the state during the relevant earning period. Moving before exercise does not necessarily remove that connection. The award type, employment history and relevant dates should be reviewed from the actual documents. California FTB: equity compensation.
Property and operating income also need attention. California continues to tax nonresidents on taxable California-source income, including specified services, real property and business income. For an owner with continuing operations, the personal move and the company's activities are separate parts of the file. California FTB: nonresident income.
| Component | Why the headline price can mislead | What the advisers need |
|---|---|---|
| Shares or business interests | An equity sale and an asset sale can produce different consequences. | The actual asset, owner, transaction form and applicable sourcing analysis. |
| Options or other equity compensation | A later exercise or payment may relate to earlier work. | Award documents, relevant dates and service-location history. |
| Earn-out | Future cash may be contingent on performance or linked to continuing services. | The precise conditions and a separate character and sourcing analysis. |
| Retention or consulting payment | Payment for ongoing work is not simply additional share proceeds. | Service obligations, work location, payer and withholding position. |
| Rollover equity | Value retained in the buyer is not cash available to pay personal obligations. | Valuation, transfer restrictions, realisation assumptions and tax treatment. |
| Escrow or holdback | A claim may delay or reduce the amount ultimately released. | Release conditions, indemnities and a conservative cash schedule. |
Suppose a buyer describes a transaction as a $10 million exit, consisting of $6 million at closing, $2 million of rollover equity, a $1 million contingent earn-out and $1 million for continued services. The founder has not received $10 million of spendable sale proceeds. The timing, certainty and treatment of the four components differ. A tax estimate that applies one percentage to the headline number conceals those differences.
These are fictional numbers, with no assumed tax result. Their purpose is to improve the questions asked in negotiations. A founder might prefer more cash at completion, accept a lower headline valuation in exchange for fewer contingencies, or retain equity deliberately. Each choice should be made with a clear view of the funds available to the household and the risks being retained.
Read the payment terms before setting the date
The date cash arrives may differ from the date relevant to sourcing. California generally sources installment gains from intangible property by residence at the time of sale; its guidance illustrates continuing California taxation of stock-sale gains paid after a seller moves away. Deferring receipt should therefore be tested on its own terms. California FTB: installment sales.
Remote work deserves the same care. For an employee whose assigned or primary office is in New York, working remotely elsewhere can still produce New York-source employment income under the convenience rule, subject to the applicable exceptions. The individual's location and the employer's arrangements both require review. New York: telecommuting guidance.
Re-run the analysis when the buyer changes the deal
A residence review prepared for an early term sheet can become incomplete when the buyer changes what is acquired, adds service conditions or proposes a different payment schedule. The family may already have moved while the economic transaction is still changing. That creates a coordination problem: the advisers need the current version of the deal, with the differences from the earlier assumptions made explicit.
Use a change register for material terms: asset versus share consideration, an election, rollover equity, contingent price, continuing employment or a new seller. Each change should prompt a focused question about character, source, timing and cash. This keeps the review attached to the transaction the parties are actually signing.
Commercial timing deserves equal attention. A plan that depends on delaying a sale may reduce negotiating leverage or expose the founder to business risk. The right decision compares that cost with the benefits supported by the full analysis. Tax planning is part of the transaction economics; it should not silently assume the buyer will accept every preferred date or structure.
Make the failed-deal scenario explicit
Relocation has costs and consequences even if the sale falls through. The owner may retain responsibility for the business, need to travel back regularly or fund two households longer than planned. Ask whether the proposed life remains attractive and whether the business can operate under those conditions. A plan that only works after the founder stops working is fragile while the founder is still essential.
| Scenario | What to model | Question that can change the decision |
|---|---|---|
| Remain through completion | Current residence, actual deal terms and post-sale choices. | What value is gained by preserving the current business and family routine? |
| Genuine move before completion | Supported residence facts, continuing source exposure and transition costs. | Does the full benefit exceed the financial and commercial costs of changing now? |
| Closing delayed | Longer business involvement, duplicate costs and later cash. | Can the household and company sustain the plan without the expected proceeds? |
| Sale abandoned | Continued ownership, work patterns and the cost of reversing course. | Would the new location still be chosen without the transaction? |
The most useful number may be the amount of immediately available cash under a less favourable case. That number determines whether the owner can meet housing, tax and business commitments without selling retained equity or borrowing unexpectedly. It also makes uncertainty easier to discuss: the founder can see which assumptions are essential and which merely improve an already workable outcome.
Build a decision file that survives the closing
A useful record has three layers. First, retain a factual chronology of homes, travel, household changes and work arrangements. Second, maintain the transaction chronology, including material changes in the proposed consideration and obligations. Third, record the tax team's conclusions for each income category, the facts those conclusions depend on and the filings needed to implement them.
This discipline gives the owner a clearer decision. It identifies the exposure that a move may affect, the exposure that continues and the assumptions that remain unresolved. It also gives commercial negotiations a more reliable foundation: a price adjustment or term change can be assessed against its actual consequence.
There is no reason to build the plan around an arbitrary waiting period. More time can allow a new life to become established, but elapsed time is evidence to assess, not a substitute for the applicable tests. The strongest plan aligns the owner's living arrangements, business obligations, transaction structure and reporting position.
