Law Professor Learns Harsh State Income Tax Lesson

Why It Matters

Employers and remote workers face unexpected multi‑state tax liabilities, raising compliance costs and payroll complexity as telework becomes permanent.

Key Takeaways

• New York applies “convenience of employer” test for remote workers.
• Remote work may trigger non‑resident state tax liabilities.
• Courts upheld NY tax despite pandemic‑induced home work.
• Reciprocity agreements can mitigate but are not universal.
• Employers must assess multi‑state tax exposure for telecommuters.

Pulse Analysis

The rise of remote work has exposed a tax blind spot that many employees and employers overlook: state income tax obligations can follow the location of the employer rather than the employee’s residence. New York’s "convenience of employer" doctrine, applied in the Zelinsky case, treats any work performed outside the state as taxable unless the employee can prove the remote arrangement serves the employer’s business needs. This legal standard creates a de‑facto nexus, allowing states to claim tax revenue from non‑residents who perform duties from home, even during extraordinary circumstances like a pandemic.

For businesses, the implications are profound. Payroll systems must now capture not only where an employee lives but also where they perform their duties on any given day. Failure to withhold the correct state taxes can trigger audits, penalties, and costly retroactive payments. Companies are increasingly turning to multi‑state tax compliance platforms and revising remote‑work policies to include clear guidelines on work‑location reporting, reciprocity agreements, and tax withholding responsibilities. HR and finance teams must collaborate to map employee work patterns against each state’s nexus rules, ensuring that both employer and employee remain compliant.

Looking ahead, the tension between state revenue goals and the flexibility of modern work arrangements may spur legislative reforms. Some states are considering amendments to the convenience test or expanding reciprocity compacts to reduce friction for telecommuters. Until uniform standards emerge, legal counsel advises proactive risk assessments and, where feasible, negotiating tax‑sharing agreements with affected states. By staying ahead of evolving tax landscapes, organizations can protect their bottom line while supporting the remote‑work models that have become integral to today’s talent strategy.
