Which State's Laws Apply to a Remote Employee?
Wage law, taxes, unemployment, workers' comp and discrimination statutes don't all answer the choice-of-law question the same way — the framework, domain by domain, plus the convenience-rule tax trap and what choice-of-law clauses can't do.

The default: physical presence
The organizing principle is old and physical: a state regulates work performed inside its borders. The remote employee in Denver is protected by Colorado law because the work happens in Colorado — the employer's headquarters, state of incorporation, and payroll address are mostly irrelevant to that question. Everything else in this guide is refinement and exception, but when in doubt, the work state wins — which is why the registration checklist treats every new work state as a new compliance domain.
Domain by domain
The tax wrinkles
Three to know. The convenience rule: New York (with Delaware, Nebraska, and a few others in various forms) taxes employees of in-state employers who work remotely elsewhere for their own convenience — a Connecticut resident working from home for a Manhattan firm can owe New York tax on those days, and the residence-state credit doesn't always make them whole. Reciprocity agreements: neighboring states (PA–NJ, the DC area, much of the Midwest) let commuters pay only their residence state — simplifying withholding where they exist. Nexus: the employee's presence can pull the company into the state's corporate income, franchise and sales-tax regimes. None of this is handbook material — it's why the offer letter shouldn't promise anything about taxes, and why finance sees the approved-states list before recruiting does.
What contracts can and can't choose
A choice-of-law clause governs the contract — interpretation, disputes about its terms — and even there, courts require a reasonable relationship and respect for fundamental policy. What it cannot do is contract around the work state's protective statutes: minimum wage, overtime, expense reimbursement, sick leave, final pay and discrimination law apply to work performed in the state whatever the clause says. California made the point statutory: Labor Code 925 lets California-based employees void out-of-state forum and choice-of-law clauses imposed as a condition of employment. The practical drafting rule: choose law for contract mechanics if you like, but build the remote work policy and the state addenda on the assumption that every work state's floor applies — because it does.
