California Remote Workers in Texas: When California Can Still Tax Your Income

The most dangerous assumption a remote worker can make is that changing a mailing address automatically ends every California tax obligation. California taxes residents on income from all sources and nonresidents on income from California sources. Determining residency and determining the source of particular income are related but separate questions [1][2].

Under California law, a person is a resident if present in California for other than a temporary or transitory purpose, or if domiciled in California while outside the state for a temporary or transitory purpose. Maintaining a California home, spending time in the state, and retaining family, financial, professional, or social connections are relevant factors, but no single one automatically establishes residency. The FTB compares the strength of the taxpayer's California connections with connections elsewhere and considers all the circumstances [1].

The good news is that a genuine move to Texas can establish nonresident status even when you retain limited California connections or occasionally return to the state. There is no general 45-day residency threshold for someone who has permanently changed domicile. Unless the narrow 546-day employment-contract safe harbor applies, residency is determined from all the facts and circumstances [1][13].

California taxes nonresidents only on income from California sources [4]. The critical question for remote workers is: is my salary from a California employer considered California source income?

The answer depends on where you physically perform the work. Under California Revenue and Taxation Code Section 17951, wages are sourced to the location where the services are actually performed, not where the employer is headquartered [4][2]. If you are a nonresident employee living in Boerne and perform all your current services from your Texas home office, your ordinary wages are generally not California-source income merely because your employer is headquartered in California. Equity compensation, deferred compensation, a California-resident spouse, or other California-source income can require a separate analysis.

This physical-work-location rule applies to compensation received as an employee. It should not be generalized to independent contractors, consultants, sole proprietors, LLC owners, partners, or S corporation shareholders. California may apply business-apportionment and market-based sourcing rules to those taxpayers, potentially creating California-source business income even when the owner performs the work from Texas [10].

The year of the move requires separate treatment. A person who moves from California to Texas during the year is generally a part-year resident: California taxes worldwide income received during the California-resident portion of the year and California-source income received during the nonresident portion [1][2].

But here is where it gets complicated. If you perform services in California during the tax year, the compensation reasonably attributable to those services is California-source income. A salaried employee commonly uses a California-workday-to-total-workday ratio, although another reasonable allocation method may apply to commissions, bonuses, equity compensation, or other forms of compensation. Whether a return must be filed depends on California's filing requirements and income thresholds [1][2][4][5]. This applies whether you are in California for a team offsite, a quarterly planning session, a client meeting, or a week at the company headquarters.

California does not have a general rule making someone a resident after 45 days in the state. Nor does spending fewer than 45 days automatically establish nonresidency.

The 45-day number belongs to a narrow safe harbor for a person who remains domiciled in California but leaves under an employment-related contract for an uninterrupted period of at least 546 consecutive days. If the requirements are satisfied, the person is treated as a nonresident during the qualifying absence. Return visits totaling no more than 45 days during a taxable year covered by the contract are disregarded [1][13].

The safe harbor does not apply if:

• The taxpayer has more than $200,000 of income from stocks, bonds, notes, or other intangible personal property in a taxable year in which the employment-related contract is in effect. For married individuals, the $200,000 test is applied separately to each spouse.
• The principal purpose of the absence is avoiding California personal income tax.

A spouse or registered domestic partner may also qualify while accompanying the employee outside California for an uninterrupted period of at least 546 consecutive days. The statutory requirements must be evaluated separately for the accompanying spouse or partner [1][13].

Most people who sell or leave their California home and permanently relocate to Texas do not need this safe harbor. Their residency is determined under the ordinary domicile and facts-and-circumstances rules. A genuine Texas domiciliary can spend more than 45 days in California without automatically becoming a resident. Conversely, someone who spends fewer than 45 days in California can remain a California resident if the purported move is temporary and California remains the person's domicile [1].

Presence Days and California Workdays Are Different

Track both of the following:

• Every calendar date on which you are physically present in California, because physical presence is relevant to the overall residency analysis.
• Every day on which you actually perform services in California, because workdays are used to allocate employee compensation.

A personal vacation day in California may be relevant to residency but does not automatically create California-source wages. A day spent working from a hotel, family home, or California office can create California-source compensation.

Facts That Can Weaken a Nonresident Position

The FTB does not publish a definitive list of residency-audit selection thresholds. The following facts do not automatically trigger an audit or establish residency, but they can create inconsistencies that require explanation if the FTB examines a return [1][6][7]:

• Keeping a California residence available for personal use, particularly when the taxpayer has not established a comparable permanent home in Texas.
• Leaving a spouse, dependent children, or the primary family home in California.
• Retaining California driver's licenses, vehicle registrations, or voter registration after claiming a permanent Texas move.
• Continuing to use California addresses on payroll, tax, banking, brokerage, insurance, or government records.
• Maintaining substantially stronger medical, professional, social, or business connections in California than in Texas.
• Reporting a major stock-option exercise, restricted-stock vesting event, business sale, or other compensation event close to the claimed move date.
• Filing federal, California, and other records that identify inconsistent residences or move dates.

The Statute of Limitations

The FTB generally has until the later of four years after a return is filed or four years after the return's original due date to issue an assessment. If a return omits more than 25% of gross income, the assessment period generally extends to six years. If no return is filed for a year in which one was required, or if a false or fraudulent return is filed with intent to evade tax, the FTB may assess tax at any time. Federal tax adjustments and other statutory exceptions can also alter the normal period [6][7].

This last point is critical. If you move to Texas, stop filing California returns entirely, and the FTB later determines you were still a California resident, they can assess back taxes for every year going back indefinitely. You cannot outrun the statute by not filing.

Some states use a "convenience of the employer" rule that can source remote wages to the employer's state even when the employee works elsewhere. California does not generally use that rule for ordinary W-2 compensation paid to a nonresident.

California ordinarily sources employee wages to the place where the employee actually performs the services. A California headquarters, payroll department, manager, or customer base does not by itself convert Texas workdays into California workdays [1][2][4].

For ordinary W-2 compensation paid to a nonresident employee, California's rule is that wages are sourced to the place where the services are actually performed. The FTB does not have general discretion to reclassify Texas workdays as California workdays merely because the employer, management team, or customers are in California [1][2].

The important exceptions involve different kinds of income, not a hidden convenience rule. Stock options, restricted stock, restricted stock units, bonuses, and other deferred compensation may be allocated partly to California based on where the employee worked during the applicable grant-to-vest, grant-to-exercise, or service period. Business income earned by a contractor, consultant, sole proprietor, partner, LLC member, or S corporation shareholder may also be governed by market-based sourcing and apportionment rules rather than the employee wage rule [3][10].

A California employer may continue California withholding because its payroll system still identifies the employee as working in California. Changing the mailing address alone may not correct the assigned work state.

A nonresident employee's ordinary wages are subject to California withholding to the extent the employee performs services in California. If all services are performed in Texas, the employer should review and correct the employee's payroll work location. If services are performed in both states, California generally uses the ratio of California workdays to total workdays to determine the California portion, unless another reasonable allocation method applies [4].

Employees should provide HR or payroll with:

• The effective date of the Texas move;
• The Texas home and work address;
• Written confirmation that Texas is the employee's regular work location;
• A record of any California workdays; and
• Any documentation required by the employer's payroll provider.

FTB Form 590 should not be used for wages. The form's official instructions specifically state that wage withholding is administered by the California Employment Development Department [9].

If California income tax was withheld from non-California wages, the employee generally must file Form 540NR to claim the withholding credit and request a refund. Do not promise a four-to-six-month refund period. Processing time varies by filing method, identity-verification issues, documentation requests, and the facts of the claim.
