The Convenience of the Employer Rule: Which States Enforce It in 2025?

The convenience of the employer rule is one of the most contested concepts in state taxation of remote work. In a normal year, a state can tax the wages of a non-resident only to the extent those wages are earned for work physically performed inside the state. The convenience rule is an exception: it allows the work state to tax a non-resident employee who works remotely for an in-state employer, unless the employee can prove the out-of-state work was required by the employer. Eight states currently enforce some version of this rule, and for affected employees it can mean filing non-resident returns and paying tax in a state where they never set foot during the year.

What the convenience rule actually says

Under the convenience rule, when a non-resident employee of an in-state employer performs work outside the state from a home office or other remote location, that work is treated as if it were performed in the employer state. The employee cannot allocate those wages away from the employer state unless the work was performed out of state for the necessity of the employer rather than the convenience of the employee. The rule flips the default physical-presence rule for one narrow category of workers: those whose employer is headquartered in the convenience-rule state but who choose to live elsewhere.

The rule is rooted in a much older principle from the early twentieth century, when railroads and traveling salesmen generated multi-state income. State tax administrators developed the convenience test to distinguish between employees whose out-of-state work was incidental or optional (still taxable at the employer location) and those whose out-of-state work was structurally required by the job itself. The modern version is most often invoked when an employee lives in one state, works for an employer in another, and telecommutes from home for some or all of the year.

The eight states that enforce the rule in 2025

Eight states assert the convenience of the employer rule as of 2025: Alabama, Connecticut, Delaware, Nebraska, New Jersey (limited), New York, Oregon, and Pennsylvania. Each state's version has its own contours, and understanding the differences matters for any employee who lives in one state and works remotely for an employer in another.

New York

New York enforces the most aggressive version of the rule, codified at 20 NYCRR 132.16. The New York State Department of Taxation and Finance treats all wages paid to a non-resident employee of a New York employer as New York-source income unless the employee's work outside New York was required by the employer's necessity. The rule applies regardless of where the employee lives and regardless of how many days were spent in New York. New York is the only convenience-rule state that aggressively litigated the rule all the way to the U.S. Supreme Court.

Connecticut

Connecticut's convenience rule is retaliatory in design. Per the Connecticut Department of Revenue Services, Connecticut taxes non-resident employees who work remotely for Connecticut employers only when the employee's home state imposes a similar convenience rule on Connecticut residents. In practice, this means the rule is triggered primarily against residents of New York (and other convenience-rule states), creating a mirror-image tax exposure for cross-border commuters.

Delaware

Delaware has long enforced a convenience rule through the Delaware Division of Revenue. A non-resident employee who works for a Delaware employer but performs some or all work outside Delaware is treated as earning Delaware-source wages for the out-of-state days, unless the out-of-state work was required by the employer. The rule is particularly impactful for residents of Pennsylvania, Maryland, and New Jersey who commute to Wilmington or Dover.

Pennsylvania

Pennsylvania applies the convenience rule to non-resident employees who work remotely for Pennsylvania employers. Per the Pennsylvania Department of Revenue, a non-resident who works from out of state for personal convenience is treated as if the work were performed in Pennsylvania, with the same wages subject to Pennsylvania personal income tax. Pennsylvania's reciprocity agreements with several neighboring states modify the picture for residents of those states in wage-withholding contexts but do not override the convenience rule for non-resident return filing.

New Jersey

New Jersey's convenience rule is narrow. The New Jersey Division of Taxation applies it to certain types of compensation paid to non-resident employees who perform services outside New Jersey for their own convenience. New Jersey does not assert the rule broadly against all W-2 wages of cross-border teleworkers, and its 2023 retaliatory credit statute signals a defensive posture toward New York rather than broad assertions against out-of-state residents.

Nebraska, Arkansas, Alabama, and Oregon

Nebraska, through guidance from the Nebraska Department of Revenue, applies the convenience rule to non-resident employees of Nebraska employers. Arkansas enforces a similar rule under Arkansas tax regulations, with the Arkansas Department of Finance and Administration issuing guidance periodically. Alabama's version applies to certain tax years for non-resident employees of Alabama employers. Oregon, which also imposes relatively high marginal rates, applies the convenience rule to non-resident employees of Oregon employers, generating significant exposure for workers in neighboring Washington and Idaho who telework for Portland- or Salem-based companies.

The two-prong test

Every convenience-rule state uses some version of the two-prong test. The first prong asks where the work was physically performed: how many days inside the state versus outside the state. The second prong asks why the out-of-state work was performed: was it for the employer's necessity or the employee's convenience? Only if the out-of-state work satisfies the necessity prong can the employee allocate those wages away from the employer state.

The first prong is mechanical. The employee maintains a calendar of workdays, identifies which days were worked inside the convenience-rule state and which were worked elsewhere, and calculates the percentage of compensation that corresponds to each. Employers typically maintain time-location records for audit purposes, and discrepancies between employee and employer records are a frequent source of audit adjustments.

The second prong is where most disputes are won or lost. The employee bears the burden of proving necessity. Necessity is not the same as approval, permission, or acceptance. The employer must actually require the work to be performed outside the state, and the requirement must arise from the nature of the job or a business reason, not from employee preference.

What "necessity" actually means

The necessity standard is narrow. Per New York's long-standing guidance, examples of employer necessity include work that must be performed at a client site, work that requires specialized equipment available only outside the employer state, and work performed in response to a regulatory or legal requirement that mandates the out-of-state location. Each of these examples shares a common feature: the employer cannot accomplish the work in the employer state, and the out-of-state location is therefore structurally required.

Convenience, by contrast, includes any reason grounded in the employee's personal preference. An employee who works from home because the commute is long, because family obligations make it easier, because the home office is more comfortable, or even because a pandemic has made office attendance less appealing is generally working for their own convenience under the rule. The pandemic-era guidance from New York confirmed this point directly: telework undertaken in response to public-health guidance but not required by the employer was treated as convenience work.

How the rule interacts with the resident-state credit

The convenience rule does not, in most cases, produce literal double taxation. The employee's resident state typically grants a credit against its own tax for income tax paid to the work state on the same wages. The credit prevents the same dollar of income from being taxed twice, but it does not eliminate the cash-flow burden. The employee pays the work-state tax first, often through withholding, and then claims the credit on the resident-state return when filing the following spring.

This timing mismatch can be a real cost. The employee may be out the work-state tax for months before the resident-state credit produces a corresponding refund or reduced liability. In some cases, the credit is capped at the resident-state tax rate on the same income, which means a high-tax work state and a lower-tax resident state can leave the employee bearing the difference. State-level differences in credit mechanics, including whether credits are refundable and how they interact with alternative minimum tax, add further complexity.

The Zelinsky saga

The most prominent constitutional challenge to the convenience rule was mounted by Edward Zelinsky, a tax professor at Cardozo School of Law who lived in Connecticut and worked for a New York employer. Zelinsky worked part of the year from his Connecticut home and argued that New York could not constitutionally tax the wages he earned in Connecticut. The New York Court of Appeals ruled against him in 2007, holding that the convenience rule did not violate the U.S. Constitution's Due Process or Commerce Clauses. The U.S. Supreme Court denied certiorari in 2008, leaving the rule intact.

The Zelinsky decision remains the leading authority on the convenience rule's constitutionality. Subsequent attempts to overturn the rule through federal legislation, including the Mobile Workforce State Income Tax Simplification Act, have not succeeded. State-level repeal efforts in New York have similarly stalled, leaving the rule firmly in place as of 2025.

New Jersey's retaliatory credit

In 2023, New Jersey enacted a retaliatory credit in direct response to New York's continued enforcement of the convenience rule against New Jersey residents. Under P.L. 2023, ch. 131, New Jersey residents who pay New York tax on wages that New York taxes solely because of the convenience rule may claim a credit against their New Jersey tax for the same amount. The credit is designed to neutralize the convenience-rule cash-flow impact for New Jersey residents, although it does not eliminate the filing burden or the underlying New York non-resident return obligation.

Connecticut took a parallel approach in 2018 with its retaliatory convenience rule, which extends Connecticut's non-resident reach to out-of-state residents whose home states apply a similar rule. Together, the New Jersey and Connecticut measures create a partial counterweight to New York's enforcement posture, but they do not dismantle the underlying rule. They simply shift the cost back to New York's treasury for affected residents of those two states.

Remote work post-COVID and audit activity

The pandemic dramatically expanded the population of cross-border teleworkers, and convenience-rule states have not relaxed their enforcement. New York's Department of Taxation and Finance has repeatedly affirmed that the rule applies regardless of the public-health emergency and that telework undertaken for the employee's convenience remains New York-source income. Audit activity has picked up accordingly, with questionnaires targeting non-resident filers who report low New York day counts but substantial New York-source wages.

The audits typically follow a recognizable pattern. The state issues a questionnaire requesting a day-by-day work location calendar, the basis for any out-of-state allocation, and the employer's written position on whether the out-of-state work was required. Discrepancies between the employee's records and the employer's records often trigger a deeper examination, and the auditor may request employment agreements, performance reviews, and emails documenting the remote-work arrangement. Successful defense generally requires contemporaneous documentation, not after-the-fact reconstruction.

How to know if the rule applies to you

The convenience rule applies to you if three conditions are met. First, you are a non-resident of the state for the tax year. Second, your employer is located in one of the eight convenience-rule states. Third, you performed some or all of your work outside that state during the year. If all three are true, you should assume the rule applies unless you can document employer necessity for the out-of-state work.

The first step is to identify your employer's state of origin and confirm whether it is a convenience-rule state. The second step is to maintain a contemporaneous calendar of work locations for the entire year. The third step is to obtain a written statement from your employer characterizing the out-of-state work as required, if such a characterization is accurate. Without all three, you should expect to file a non-resident return reporting 100 percent of your wages as work-state source income.

Planning around the rule

Several planning strategies can reduce or eliminate convenience-rule exposure. The most straightforward is relocation: an employee who moves to a state with no income tax, or who moves into the employer state and becomes a resident, eliminates the non-resident exposure entirely. A second strategy is changing employers: an employee who switches to an employer in their resident state, or in a non-convenience-rule state, removes the rule from the equation. A third strategy is restructuring the work itself so that the out-of-state component is documented as employer-necessity work, supported by a written designation and a clear business reason.

More aggressive restructurings, such as reclassifying the worker as an independent contractor or routing the relationship through a professional employer organization, can change the analysis but introduce their own risks. Independent-contractor status raises IRS classification concerns and may not be available for genuine employees. Professional employer organizations can shift the legal employer for payroll purposes, but the cost is significant and the arrangement must be structured carefully to avoid being treated as a sham.

What to do if you are under audit

If you receive a convenience-rule audit questionnaire, the first step is to calendar the response deadline and avoid missing it. Late or incomplete responses often result in automatic adjustments that are difficult to undo. The second step is to assemble your documentation before responding: your day-count calendar, your employment agreement, any written necessity designation, and records of any in-state work performed. The third step is to consider engaging a CPA or tax attorney with specific convenience-rule experience, particularly if the wages at issue are substantial.

Audit defense is often won or lost on documentation quality. Auditors are trained to look for after-the-fact reconstructions and self-serving statements unsupported by employer records. The strongest defenses rest on contemporaneous documentation: calendars maintained during the year, written employer designations made before any audit, and a clear paper trail showing why the out-of-state work was required. If you cannot produce this kind of evidence, the audit is likely to result in an assessment of additional work-state tax, plus interest and penalties.

What to do next

Start by identifying whether your employer is located in one of the eight convenience-rule states. If it is, build a contemporaneous workday calendar and request a written characterization of any out-of-state work from your employer. If you are already in an audit, gather your documentation and consider professional representation.
