California has one statutory residency safe harbor, often called the 546-day rule. It is frequently misunderstood. It is not a general day-count test for people who spend little time in California. It applies only to a California domiciliary who is outside the state under an employment-related contract, and only if specific conditions are met.
What the Statute Says
Revenue and Taxation Code (R&TC) section 17014(d) provides that, for taxable years beginning on or after January 1, 1994, an individual domiciled in California who is absent from the state for an uninterrupted period of at least 546 consecutive days under an employment-related contract is considered outside California for other than a temporary or transitory purpose. The Franchise Tax Board (FTB) treats an individual who meets the safe harbor as a nonresident.
Without the safe harbor, a California domiciliary who leaves for work but intends to return could remain a California resident, because a person domiciled in California who is outside the state for a temporary or transitory purpose is a resident (R&TC § 17014(a)).
The Conditions
California domicile. The safe harbor is written for individuals domiciled in California. Someone who has already established a domicile elsewhere is evaluated under the general residency rules.
An employment-related contract. The absence must be under an employment-related contract.
At least 546 consecutive days. The absence must be uninterrupted and last at least 546 consecutive days.
Limited return visits. Returns to California totaling not more than 45 days during a taxable year are disregarded (R&TC § 17014(d)(1)). FTB Publication 1031 describes return visits that do not exceed a total of 45 days during any taxable year covered by the employment contract as temporary.
Intangible income limit. The safe harbor does not apply to any individual, including an accompanying spouse, who has income from stocks, bonds, notes, or other intangible personal property of more than $200,000 in any taxable year in which the employment-related contract is in effect (R&TC § 17014(d)(2)).
No tax-avoidance purpose. The safe harbor does not apply if the principal purpose of the absence is to avoid California personal income tax (R&TC § 17014(d)(4)).
The 45-day limit is measured for each taxable year covered by the contract. Tracking days in California throughout each year, with supporting travel records, is essential to relying on the safe harbor.
Accompanying Spouses
A spouse who is absent from California for an uninterrupted period of at least 546 consecutive days to accompany an individual who qualifies is also considered outside California for other than a temporary or transitory purpose (R&TC § 17014(d)(3)). FTB Publication 1031 applies the same treatment to a registered domestic partner.
What the Safe Harbor Does Not Do
The safe harbor addresses residency, not California-source income. Nonresidents are still taxed on income from California sources, such as compensation for services performed in California, rent from California real property, and gain from the sale of California real property.
It also does not help someone whose assignment ends early. If the absence lasts less than 546 consecutive days, the safe harbor does not apply and the general rules govern. The FTB notes that a person who temporarily relocates to another state for employment but plans to return may still be considered a California resident, taxed on worldwide income, with a possible credit for taxes paid to the other state.
Records to Keep
A taxpayer relying on the safe harbor should keep the employment contract and assignment letters showing the expected duration; a calendar of days spent in California for each taxable year, supported by travel records; records of investment income for each year the contract is in effect; and documentation of the business reasons for the assignment.
The Bottom Line
The 546-day rule is a narrow but useful safe harbor for Californians who leave the state to work under an employment-related contract. It requires an uninterrupted absence of at least 546 days, limited return visits, intangible income of $200,000 or less each year, and a genuine purpose other than avoiding tax. Careful records are what make it work.
