Remote work can create a state nonresident tax issue even when an employee never changes employers. The result usually depends on several facts at once: where the employee is a resident, where the work is physically performed, where the employee’s assigned office is located, whether a state applies a convenience-of-the-employer rule, and whether the states involved have a reciprocal agreement.
The employer’s headquarters or payroll address does not, by itself, decide where wages are taxable. In many states, the physical location where services are performed is the starting point. Other states use rules that can treat days worked remotely outside the state as in-state workdays under certain circumstances.
State nonresident status is separate from federal nonresident alien status. A person can be a nonresident alien for federal income tax purposes and still have a state residency or state-source income question. A U.S. citizen or resident alien can also be a nonresident of a particular state.
Four Locations Can Matter for the Same Remote Job
A remote employee may have four different locations connected with one paycheck. Treating them as interchangeable is a common reason state wage sourcing becomes confusing.
| Location | Why It Can Matter |
|---|---|
| Resident state | A resident state may tax a resident’s income even when the work producing that income was performed elsewhere, subject to that state’s rules and available credits. |
| Physical work location | Many states source employee compensation according to where the services were actually performed. |
| Assigned or primary office | This can become especially relevant in states that use a convenience-of-the-employer test. |
| Employer headquarters or payroll location | This may be relevant to withholding or employer administration, but it does not automatically determine the legal source of an employee’s wages. |
Consider an employee who lives in Connecticut, works from a Connecticut home three days each week, reports to an assigned office in New York City, and works in that office two days each week. Physical location points to two states. Residence points to Connecticut. The assigned office points to New York. New York’s convenience rule can then change how some of the Connecticut remote days are treated.
Physical Work Location Is the Starting Point in Many States
Some states use a relatively direct approach to wages earned by nonresidents: compensation follows the place where the employee performs the services.
California provides a clear example. The California Franchise Tax Board states that personal-service income is sourced according to where the services are performed. A nonresident performing services entirely outside California does not create California-source compensation merely because the employer is located in California or payment originates there. Services actually performed in California can produce California-source income.
This distinction matters for remote employees of California companies. Working for a company headquartered in San Francisco is not the same fact as physically working in San Francisco. The employee’s actual work location remains central to California’s sourcing analysis.
Massachusetts Shows How Workday Allocation Can Operate
Massachusetts uses workday allocation in situations where a nonresident employee works both inside and outside the state and the exact amount attributable to Massachusetts cannot otherwise be established.
The Massachusetts regulation uses the following general allocation for employees covered by its workday rule:
Compensation × Massachusetts workdays ÷ total working days
The regulation gives a telecommuting example involving an employee who works mainly from home in Ohio for a Massachusetts firm. The employee earns $120,000, works 240 days during the year, and spends 60 workdays in Massachusetts. The example allocates $30,000 to Massachusetts: $120,000 × 60 ÷ 240.
That calculation illustrates Massachusetts law; it is not a universal remote-work formula. Another state may define workdays differently, use a different allocation method, provide an exception, or apply a convenience rule instead.
Convenience Rules Can Change the Physical-Location Result
A convenience-of-the-employer rule addresses a different question: why was the work performed outside the employer’s state?
Under this type of rule, an employee’s out-of-state workday may sometimes remain sourced to the employer’s state when the employee works elsewhere for personal convenience rather than because the employer requires the work to be performed there.
| Situation | Tax Issue |
|---|---|
| Employee chooses to work from a home in another state even though the job could be performed at the employer’s office | A convenience rule may treat the remote day as a day worked in the employer’s state. |
| Employer requires work at an out-of-state customer site | The facts may support employer necessity because the work must occur at that location. |
| Specialized facilities needed for the work exist only outside the employer’s state | The physical location may have a direct business reason rather than merely serving the employee’s preference. |
| Employer simply permits remote work from anywhere | Permission to work remotely is not necessarily the same as requiring work in a particular out-of-state location. |
The distinction can be narrow. A remote-work agreement saying that an employee is permitted to work from home does not necessarily establish that the employer needed the employee to work from that home, in that state.
New York Can Treat Out-of-State Remote Days as New York Workdays
New York is one of the states where physical location alone may not settle a nonresident employee’s wage allocation.
New York’s nonresident instructions state that when an employee’s assigned or primary office is in New York, an allowance for days worked outside New York generally depends on services performed outside the state because of the employer’s necessity rather than the employee’s convenience. Normal days worked at home can therefore be treated as New York workdays when the employee’s assigned or primary work location is a New York employer office.
New York also recognizes a separate concept known as a bona fide employer office. If a qualifying home office meets New York’s requirements, the treatment can differ. A home office does not become a bona fide employer office merely because an employee regularly uses it or because an employer allows remote work.
This makes the assigned office an especially relevant fact for a remote employee connected to New York. A Connecticut resident who reports to a New York office can face a different sourcing analysis from an employee of the same company whose assigned office is outside New York.
The 2026 Zelinsky Decision Reinforced the Employer-Necessity Test
On July 2, 2026, the New York Appellate Division, Third Department issued its decision in Matter of Zelinsky v Commissioner of Taxation and Finance of the State of New York. Edward Zelinsky, a Connecticut resident and Cardozo Law School professor, had worked both in New York and from his Connecticut home during the 2019 and 2020 tax years.
The dispute included remote work performed after the COVID-19 shutdown prevented normal on-campus instruction. Zelinsky argued that the pandemic circumstances made his Connecticut work necessary rather than convenient. The court upheld the Tax Appeals Tribunal’s determination that the relevant remote income remained New York-source income.
The court distinguished between being required to work away from the New York campus and being required by the employer to work in Connecticut specifically. According to the decision, the law school needed remote instruction but did not depend on Zelinsky delivering that instruction from Connecticut. He could have performed the remote duties from another location.
The decision also discussed earlier cases in which employer necessity was supported by facts such as working near out-of-state construction clients or using specialized equipment unavailable at the employer’s New York office. By contrast, work that could be performed from many locations, such as writing, research, telephone work or similar duties, has generally presented a weaker employer-necessity argument under New York’s rule.
The 2026 decision does not mean every employee of a New York company has all remote wages sourced to New York. Assigned work location, actual New York workdays, the nature of the duties, employer necessity and the bona fide employer office rules can affect the analysis.
New Jersey Uses a Reciprocal Convenience Approach
New Jersey’s system is different from a blanket rule applying to every nonresident remote employee.
For tax years beginning on or after January 1, 2023, New Jersey applies a convenience sourcing rule to certain nonresident employees when the employee’s resident state imposes a similar test on New Jersey residents. New Jersey describes this as a reciprocal approach rather than its own universally applicable convenience rule.
For example, New Jersey explains that a New York resident telecommuting for a New Jersey employer may have wages sourced under a test based on New York’s convenience rule. New Jersey’s guidance also says the rule generally requires some minimum connection to New Jersey; simply being employed by a New Jersey employer without performing services in New Jersey does not automatically establish the required connection under the state’s current guidance.
Pennsylvania residents receive different treatment because New Jersey and Pennsylvania have a reciprocal personal income tax agreement covering employee compensation. New Jersey’s published guidance also treats Connecticut separately based on the reciprocal design of Connecticut’s convenience statute.
Connecticut Can Mirror Another State’s Convenience Rule
Connecticut also uses a reciprocal form of the convenience test. For taxable years beginning on or after January 1, 2019, Connecticut applies similar sourcing treatment to residents of states that use a convenience-of-the-employer rule when they work for a Connecticut employer.
Connecticut’s Department of Revenue Services uses a New York resident working remotely for a Connecticut employer as an example. If the employee’s resident state applies a convenience test, Connecticut can apply a corresponding test in determining whether remote wages are Connecticut-source income.
For other nonresidents, Connecticut’s ordinary rule generally looks to compensation for services performed in Connecticut. The state’s own examples distinguish an employee who works entirely outside Connecticut from one who performs services partly inside the state.
Pennsylvania Applies a Convenience-of-the-Employer Doctrine
Pennsylvania states that a nonresident is generally taxed on Pennsylvania-source compensation and that services performed within Pennsylvania normally create Pennsylvania-source compensation. Its convenience doctrine can affect the allocation when services are performed elsewhere.
Pennsylvania focuses on whether the out-of-state work was performed for the employer’s benefit and whether the duties could have been performed at an employer office inside Pennsylvania. Work that must occur elsewhere because of its nature or because specialized facilities are unavailable at or near the Pennsylvania office can receive different treatment from work performed remotely solely because the employee prefers another location.
This also shows why the phrase “remote employee” is not enough to determine a tax result. Two employees with the same employer, salary and residence can have different facts if one has duties that must be performed outside Pennsylvania while the other performs portable office work from home.
Nebraska’s 2025 Changes Make Older State Lists Unreliable
Nebraska changed its rules for nonresident compensation for taxable years beginning on or after January 1, 2025. This is one reason older articles that place states into permanent “convenience rule” lists can become inaccurate.
The Nebraska Department of Revenue’s explanation of LB 1023 introduces rules tied to whether a nonresident performs services in Nebraska for more than seven days during the tax year. It also provides a limited exception for certain nonresident employees who are in Nebraska for a conference or training for seven days or less, work in more than one state during the year, and have no more than $5,000 of wages earned while in Nebraska.
Nebraska also expressly identifies work-location records that can matter for employer withholding administration, including time-and-attendance systems, employer records, travel records, travel-expense records and written statements concerning days spent performing services in Nebraska.
For remote employees, the practical lesson is narrower than assigning Nebraska a permanent label: use the rule applicable to the actual tax year rather than relying on an old multistate telework chart.
Reciprocity Is Not the Same as a Convenience Rule
A reciprocal tax agreement can produce a very different result from a convenience-of-the-employer rule.
Reciprocity generally arises when two states agree that qualifying wage income of residents of one state will not be taxed by the other state under specified conditions. A convenience rule, by contrast, determines where remote wages are sourced. The two concepts should not be treated as substitutes for each other.
Virginia illustrates how reciprocity can operate. Virginia currently identifies reciprocal treatment involving Kentucky, Maryland, the District of Columbia, West Virginia and Pennsylvania, although the conditions are not identical for every jurisdiction. Its guidance for Maryland, Pennsylvania and West Virginia residents, for example, includes conditions involving residency, days in Virginia, maintenance of an abode and the type of income received.
Reciprocity may also be limited to wages or salaries. Income from a business, pass-through entity, rental property or another source can follow separate rules even when employee wages receive reciprocal treatment.
Convenience rule: asks where remote employee compensation is sourced.
Reciprocity: can exempt qualifying wages from taxation by the work state under an agreement between states.
Resident tax credit: can reduce overlapping taxation after income is taxable in more than one jurisdiction.
Two States Can Have a Tax Claim on the Same Wage Income
A resident state may tax a resident’s income while another state treats some or all of the same wages as nonresident source income. That can create filing obligations in more than one state without necessarily producing two full layers of final tax on the same income.
Many states provide some form of credit for qualifying income taxes paid to another state, but the mechanics vary. The credit may be limited to a portion of the other state’s tax or to the resident state’s tax attributable to the same income. Particular income can also fail to meet a state’s credit rules.
New York, for example, provides a nonrefundable resident credit in qualifying situations involving income sourced to and taxed by another state, local government within another state or the District of Columbia. New York’s own guidance explains that a person living in one state and working in another can have liability in both states while a resident-state credit may reduce double taxation.
This distinction matters in convenience-rule cases. The existence of a resident credit does not change the employer state’s sourcing rule. It is a separate step in determining the overall state tax result.
A W-2 State Entry Does Not Create the Sourcing Rule
State wages and withholding reported on Form W-2 are useful evidence of how payroll treated an employee, but payroll treatment and legal wage sourcing are not the same inquiry.
An employer may withhold tax for a state because of the employee’s work location, assigned office, residency information or payroll setup. The employee’s state tax return then applies the relevant state’s residency, sourcing, allocation and credit rules. A withholding amount can therefore be higher or lower than the eventual state tax attributable to that income.
A mismatch can arise after an employee moves, changes an assigned office, begins working in another state, starts traveling between locations, or works remotely without updating payroll records. The W-2 should not be treated as proof that the state’s legal sourcing determination is correct simply because tax was withheld there.
Remote Workday Records Can Affect the Allocation
Work location is often a day-by-day fact. A calendar that says “remote” is less useful than a record identifying the state where the work occurred.
- Dates worked in each state
- Office attendance records
- Business-travel dates
- Employer-assigned or primary office
- Remote-work agreements and changes to those agreements
- Travel and expense records
- Time-and-attendance records
- Documents explaining why work had to be performed at a particular location
- Dates of a permanent move or residency change
- State wages and withholding reported on payroll statements and Form W-2
The distinction between a business trip and a remote workday can matter as well. A person who normally works from home in one state but spends several days working at an employer office, customer location or training site in another state may have in-state workdays under that state’s rules.
Changing States During the Year Adds a Residency Question
A permanent move during the tax year can turn a remote-work sourcing problem into a combination of resident, part-year resident and nonresident rules.
Suppose an employee lives and works remotely in State A through June, moves to State B in July, and continues working for the same employer for the rest of the year. The employee’s residence has changed, but the employer, assigned office and job duties may not have changed. Wages may therefore need to be examined by period rather than treating the entire year’s compensation as if the employee had one residence and one work location.
The date of the move, domicile facts, statutory residency rules, physical workdays and the sourcing law of any employer state can all become relevant. A change of mailing address alone does not establish every state residency issue.
Employees and Independent Contractors Can Face Different Sourcing Rules
Convenience-of-the-employer rules are primarily discussed in the context of employee compensation. A freelancer, consultant or other independent contractor may instead encounter state rules for business income, personal services, apportionment or business activity.
That distinction can change the analysis even if the actual work looks similar. A W-2 employee working remotely from a home office and an independent consultant performing the same technical task from the same room should not automatically assume that identical state sourcing rules apply.
Living in a State Without a General Individual Income Tax Does Not End the Analysis
A remote worker’s residence in a state that does not impose a general individual income tax does not prevent another state from taxing wages that the other state treats as its source income.
For example, the absence of a general wage income tax in the employee’s home state does not determine whether New York can source wages to New York under its own rules. The employer state’s sourcing analysis occurs independently of whether the resident state ultimately imposes an individual income tax.
This can also affect the practical value of an other-state tax credit. If the residence state does not impose the relevant tax in the first place, there may be no resident-state income tax against which such a credit would operate.
The Same Remote Job Can Produce Different State Outcomes
| Work Pattern | Main Issue to Examine |
|---|---|
| Employee lives in Ohio, works almost entirely in Ohio, and visits a Massachusetts office for 60 of 240 workdays | Massachusetts workday allocation can become relevant for the days worked in Massachusetts. |
| Connecticut resident works from home but has an assigned New York office | New York’s convenience rule, employer necessity and bona fide employer office rules can matter in addition to physical location. |
| New York resident telecommutes for a New Jersey employer | New Jersey’s reciprocal convenience sourcing rule may require analysis based on New York’s convenience test and the employee’s connection with New Jersey. |
| Pennsylvania resident earns only wages from qualifying work in New Jersey | The Pennsylvania-New Jersey reciprocal agreement can be more relevant than the ordinary nonresident wage sourcing approach. |
| Nonresident employee performs all services outside California for a California company | California’s physical-service sourcing rule generally focuses on where the services were performed rather than the employer’s location. |
| Employee lives in one state, moves permanently to another, and keeps the same remote job | Part-year residency and work-location allocation may need to be separated into periods before and after the move. |
Which Rule Comes First?
A remote-wage analysis becomes clearer when the facts are separated before any state tax calculation is attempted.
- Identify the state or states of residence for the tax year. A move or statutory residency rule can create more than one relevant residency period.
- Identify where the employee physically worked. Separate home days, employer-office days, customer-site days and business travel by state.
- Identify the assigned or primary employer office. This can matter even when the employee rarely enters that office.
- Determine how each work state sources nonresident employee compensation. A physical-location rule and a convenience rule can produce different results from the same facts.
- Check whether employer necessity changes remote-day treatment. Employer permission to work remotely and employer necessity are not equivalent concepts.
- Check for reciprocity between the states involved. A reciprocal wage agreement can alter the normal work-state treatment for qualifying employees.
- Compare payroll withholding with the legal sourcing result. Withholding can provide useful information without settling the final allocation.
- Determine whether the resident state provides a credit for qualifying tax paid elsewhere. Credit rules are separate from the nonresident state’s sourcing rules.
The tax year matters throughout this process. State telework rules can change through legislation, regulations, administrative guidance and court decisions. Nebraska’s rules changed beginning in 2025, New Jersey’s reciprocal convenience rule began in 2023, and New York’s convenience doctrine received a new appellate decision in July 2026. A rule summarized correctly for an earlier year may not describe a later year accurately.
