Remote work may have removed the daily commute, but it has not removed state borders from the U.S. tax system.
If you live in one state, work for a company connected to another, and sometimes perform your job from several locations, the apparently simple question βWhere do I pay tax?β can become surprisingly complicated.
There is no single U.S. rule. New York continues to apply its well-known convenience-of-the-employer framework. New Jersey responds to similar rules used by certain other states. Connecticut has created additional relief for some residents who successfully challenge another state’s convenience rule. Nebraska changed important nonresident rules beginning in 2025.
Why Remote Work Creates a State-Tax Problem
Consider a worker who lives in New Jersey, is assigned to a Manhattan office and spends most of the week working from home.
It might seem intuitive that days physically worked in New Jersey should simply be New Jersey workdays.
New York does not always see it that way.
Under New York’s current nonresident instructions, normal home-working days may still be treated as New York workdays when the employee’s assigned or primary workplace is a bona fide employer office in New York. Work performed outside New York because of genuine employer necessity can receive different treatment.

Remote Work Taxes by State: A Practical Comparison
| State | Current approach | Remote worker issue to watch |
|---|---|---|
| New York | Convenience-of-the-employer framework | Assigned office, employer necessity and bona fide employer-office rules |
| New Jersey | Responds to similar convenience rules imposed by certain other states | Resident state, NJ employer connection and whether work is for employee convenience |
| Connecticut | Reciprocal convenience framework plus resident relief | Cross-state claims and credits following successful challenges |
| Nebraska | Revised nonresident rules effective from 2025 | Physical workdays, seven-day thresholds and convenience compensation |
The Five Questions That Usually Matter
New York: The Rule Remote Workers Need to Understand
New York remains one of the clearest examples of why remote workers cannot look only at their home address.
For a nonresident whose assigned or primary workplace is an established New York employer office, New York’s instructions distinguish between work performed outside the state because of the necessity of the employer and work performed elsewhere primarily for the convenience of the employee.
Worker A
The employer closes the worker’s New York office and formally assigns the employee to a workplace outside New York.
Worker B
The employer keeps the employee assigned to Manhattan but allows the employee to work from home because commuting is inconvenient.
The physical act of opening a laptop at home may look the same. The tax analysis may not be.
New Jersey: When One State Responds to Another
New Jersey does not describe itself as imposing a universal convenience rule on every nonresident telecommuter. Instead, its law applies a similar test to residents of states that impose comparable rules.
Current guidance also makes an important distinction: if an affected nonresident performs no services in New Jersey during the calendar year, a minimum connection is generally required and wages are not allocated to New Jersey under this specific rule simply because the employer is located there.
Nebraska: A Real Rule Change From 2025
Nebraska changed its treatment of certain compensation earned by nonresidents for taxable years beginning on or after January 1, 2025.
Nebraska’s seven-day concept
Special rules may protect certain short-term conference or training wages when all statutory requirements are satisfied.
Nonresident sourcing rules require closer analysis when services are performed in Nebraska for more than seven days.
Connecticut Is Also Responding to Cross-State Tax Conflicts
Connecticut created an additional credit for certain residents who successfully challenge another state’s application of a convenience-of-the-employer rule.
The credit is equal to 60% of the specified additional Connecticut tax described by the state’s guidance.
How Is This Different From South Korea?
For someone familiar with South Korea, the American system can feel particularly unusual.
πΊπΈ United States
- State residence
- Physical work location
- Assigned employer office
- Convenience rules
- Nonresident filing
- Interstate tax credits
π°π· South Korea
- Employment relationship
- Employee vs independent contractor
- Employer / workplace relationships
- Income classification
- Social insurance
- Individual tax filing where applicable
Moving a laptop from Seoul to Busan does not normally create the same state income-tax sourcing dispute that can arise when a U.S. employee moves between New York and New Jersey.
Working for Two Companies in Korea
A person can have genuine employment relationships with more than one business. Remote work does not automatically convert either job into freelance work.
Korea’s National Pension system recognises people working at two or more covered workplaces, while Employment Insurance follows different multiple-employment rules and generally establishes insured employee status through one workplace according to statutory priority rules.

What About Korea’s β3.3%β Withholding?
In Korea, freelance income is often casually described as β3.3% work.β
But an employee cannot simply choose 3.3% withholding because remote work feels like freelancing. The substance of the working relationship matters.
| Relationship | General tax treatment |
|---|---|
| Employment | Compensation under an employment or similar dependent relationship is generally employment income. |
| Independent activity | Continuing independent services without an employment relationship can be treated as business income. |

Why This Matters for Digital Nomads
Digital nomads often begin thinking about taxation only after crossing an international border.
But international remote work can add several separate compliance layers:
- personal tax residence;
- employment-income taxation;
- payroll obligations;
- social security;
- permanent establishment;
- immigration permission;
- insurance; and
- employer compliance.
Can You Work Remotely While Travelling? Employer, Visa, Tax and Insurance Checklist β
A Remote Worker Checklist Before Going Abroad
- Your legal state or country of residence.
- Your employer’s assigned or primary office.
- Every jurisdiction where you physically perform work.
- The number of workdays spent in each jurisdiction.
- Whether your employer requires or merely permits remote work.
- Whether your remote location is formally recognised.
- Which jurisdiction’s tax is withheld from your pay.
- Whether tax credits are available elsewhere.
- Whether cross-border work has employer approval.
- Whether social-security or insurance obligations change.
Working Abroad? Tax Is Only One Part of the Problem
For longer stays, also check territorial insurance coverage, trip-duration limits, medical coverage, emergency evacuation and local health-insurance requirements.
Remote work abroad for weeks or months?
SafetyWing offers insurance products designed for people travelling or living internationally. Compare the actual policy coverage and exclusions with your destination and trip length before purchasing.

Security Matters When Your Office Moves With You
If you use an employer-issued device, company security policy comes first. Never use a VPN to bypass geographic or corporate-access restrictions.
Working on public or unfamiliar Wi-Fi?
A VPN can help protect network traffic, but it does not make phishing safe and it does not change where you physically performed work for tax purposes.
Check NordVPN βAffiliate link. A VPN does not change tax residence, wage sourcing or immigration status.
Build a Backup Internet Plan Too
Before relying on mobile data abroad, check hotspot permissions, high-speed limits, local coverage and whether your employer’s VPN and MFA systems work correctly.

Bottom Line
Remote work changed faster than many tax systems.
New York continues to apply a strong convenience-of-the-employer framework. New Jersey responds to similar rules used by certain other states. Connecticut has added protection for some residents challenging another state’s rule. Nebraska revised important nonresident provisions beginning in 2025.
South Korea illustrates a different structure, where employment relationships, income classification and social-insurance status often become the starting point.
In the United States, another question often has to be added: Which state claims the income?
