The rule, the boundary, and the records—up front
This is the shortest source-mapped path to the SpaceX answer. Use the public rule first, then match it to the employee’s actual plan, award, dates, and records.
| Answer layer | What the current record says | Where to verify it |
|---|---|---|
| Public rule | What current sources establish The award agreement establishes the service and event terms; state law and payroll records establish sourcing. A final prospectus or federal plan does not answer a multistate return. | |
| Where it changes | Exceptions and population boundaries Temporary assignments, remote work, statutory residency, community property, nonresident returns, credits, and option-specific sourcing can differ. |

Public sources establish the baseline. The governing plan, award, account, and employment records establish the employee-specific result.
Moving does not erase where you worked
Your current address is only one point on a longer timeline
Consider an employee who receives a SpaceX award while working in California, works later in Texas, settles the award after another move, and eventually sells shares from a third state. It is natural to assume the state you live in when the money arrives is the state that taxes it. But the current address does not erase where the services behind the award were actually performed, and more than one state may have a claim on the same income.
SpaceX’s public filings will not resolve this, because federal equity plans do not decide state sourcing. The award agreement establishes the service and event terms, while state law and payroll records establish which state gets to tax what. Each state’s rules—turning on award type, service period, residency, domicile, community-property treatment, and employer reporting—can produce a different result, and a final prospectus or federal plan simply does not answer a multistate return.
Reconstruct the workdays first
Rebuild the grant-to-vest map before the records scatter
The risk is a timing mismatch: payroll withholding may cover one state while another claims a slice of the same sourced income, and residency rules can add filing obligations or credits on top. When workday records go missing, the allocation becomes far harder to defend years later, when the portal or your memory has lost the detail. Changing your payroll address, worth noting, does not by itself prove a change of domicile—that turns on broader facts like housing, licensing, voting, family, and travel.
So map the dates while they are still recoverable: grant, vesting service, exercise or settlement, the move, domicile, remote-work periods, and the sale. Reconcile the employer’s withholding against the states that may require returns. These are the records that make the allocation stand up:
- Grant-to-vest employment locations
- Residency and move evidence
- Payroll state withholding
- Exercise or settlement dates
- State returns and credit calculations
One map, from payroll to filing
The same record answers the sourcing question and the later notice
Several situations can complicate the picture further: temporary assignments, remote work, statutory residency, community property, nonresident returns, credits for taxes paid to another state, and option-specific sourcing rules can each change the answer. This is genuinely state-by-state territory, and it is the kind of question where state-specific tax advice earns its keep rather than a general rule of thumb.
The finished file should be able to explain, in plain terms, why income was reported to each state, what withholding occurred, and where credits were claimed. That same map supports your estimated payments now and stands ready to answer a later notice—so you are not reconstructing years of movement from scratch under a deadline.

Frequently asked questions
Questions to take back to the documents
If I move from California to Texas before SpaceX RSUs settle, is all income Texas income?
Do not assume so. California or another state may source part of the compensation to services performed there during the award period. Obtain state-specific advice.
Does changing my payroll address prove a change of domicile?
No. Domicile and residency use broader facts. Keep housing, licensing, voting, family, work, travel, and other evidence relevant to the states involved.
Why should I save workday calendars for equity awards?
Some states allocate equity compensation using service days between grant and vesting or another event. Accurate historical work locations support that calculation.
