Summary. One employee working in a new state makes a company a multistate employer subject to that state's entire employment regime, its payroll tax registrations, and usually its business income and sales tax nexus. The obligations attach from the first day of work, and most are invisible until a claim, an audit, or a notice arrives. This checklist runs the state-by-state review: registrations before the first paycheck, the wage and hour differences that catch employers paying only weekly overtime, leave and notice mandates, pay transparency and salary history rules that reach remote postings, restrictive covenant limits that can void an agreement on relocation, and the handbook and posting architecture that keeps it maintainable.

What this checklist is for. Adding a state, or auditing an existing multistate footprint. For the framework, see Managing a Multistate Remote Workforce.

Phase 1 — Establish where people actually work

  • Reconcile the HRIS work location field against payroll addresses, IP geolocation, expense reports, and manager knowledge. Most companies cannot produce this on demand, and every item below depends on it.
  • Confirm the field is required at hire and on any change, and audited quarterly.
  • Identify any employee working outside the United States, which is an entirely different analysis.
  • Identify employees who travel to other states regularly, because several states impose withholding after a threshold number of days or dollars.
  • Adopt an approved work locations policy with a request process and a defined lead time, so registrations can precede the first paycheck.

Phase 2 — Registrations, before the first payroll

For each state where an employee performs work:

  • Foreign qualification with the secretary of state, and a registered agent.
  • Income tax withholding registration.
  • Unemployment insurance account.
  • Paid family and medical leave program registration where the state has one.
  • State disability insurance where applicable.
  • Workers' compensation coverage confirmed in writing by the broker for that state, with any required endorsement — home-state extraterritorial and reciprocity provisions cover temporary work, not a permanent relocation, and a few states are monopolistic, requiring coverage from the state fund.
  • Local registrations — several cities impose payroll taxes, business licenses, and their own paid leave ordinances.
  • New hire reporting to the state directory, generally within 20 days.
  • Involve tax advisors: an employee in the state generally creates corporate income tax nexus, frequently sales tax nexus, and possibly franchise or gross receipts tax obligations. The employment registration is the visible obligation; the tax registration is often the larger one.
  • Run the deregistration sequence when the last employee leaves a state, because dormant accounts generate notices and penalties for unfiled returns for years.

Phase 3 — Wage and hour differences

  • Minimum wage — the highest of federal, state, and local, with many localities setting their own and many indexing on January 1.
  • Daily overtime above 8 hours, double time above 12, and seventh consecutive day premiums, which exist in several states and which an employer paying only weekly overtime is missing.
  • Exempt salary thresholds above the federal level in several states, some set as a multiple of the state minimum wage and rising annually — so an employee properly exempt in one state may be non-exempt in another at the same salary.
  • Duties tests that are narrower than the federal regulations in a few states.
  • Meal and rest breaks, with premium pay for missed or interrupted breaks in several states, and a practical need for scheduling and certification where work is remote.
  • Reporting time pay, split shift premiums, and on-call pay rules.
  • Pay frequency requirements, which vary by state and sometimes by employee category.
  • Wage statement content, itemized as each state prescribes — several impose per-employee, per-period penalties for defective statements, and the payroll provider's default template frequently does not comply.
  • Deduction restrictions and written authorization requirements.
  • Expense reimbursement obligations, which in several states extend to a reasonable portion of home internet and mobile phone for remote employees. A documented monthly stipend is the workable answer.
  • Final pay deadlines — immediately on involuntary termination in several states — with waiting time penalties, and the state's rule on whether accrued vacation must be paid out.

Phase 4 — Leave, benefits, and training mandates

  • Paid sick leave, mandated in a growing number of states and localities with differing accrual rates, caps, carryover, permitted uses, documentation limits, and notice requirements. A single national policy meeting the most generous requirement is administratively simpler and costs more.
  • Paid family and medical leave programs, with contribution, notice, and coordination rules.
  • Other mandated leaves — jury duty, voting, domestic violence, school activities, bereavement, organ donation, military, and crime victim leave.
  • State family and medical leave statutes that apply at lower thresholds than the FMLA or provide longer entitlements.
  • Mandatory harassment prevention training, with prescribed frequency, duration, content, and separate supervisor requirements.
  • State-mandated retirement programs, which require employers without a plan to enroll employees in a state-facilitated IRA, with thresholds as low as one employee and registration deadlines carrying penalties.
  • Health plan network adequacy for a relocated employee, and any state insurance mandate that applies.
  • COBRA and state continuation requirements, several of which apply to smaller employers than COBRA does.

Phase 5 — Hiring, pay practices, and restrictive covenants

  • Pay transparency — salary ranges in job postings, required in a growing number of jurisdictions and applicable to remote roles that could be performed there, which for a nationally posted role means the strictest requirement effectively governs.
  • Pay data reporting obligations where they exist.
  • Salary history bans — remove the question from applications and train recruiters, because a single screening-call question is the violation.
  • Ban-the-box and criminal history inquiry restrictions, including timing, individualized assessment, and notice requirements.
  • Credit history inquiry restrictions.
  • Background check consent and disclosure requirements under the FCRA and any stricter state analogue.
  • Marijuana testing restrictions, which in a growing number of states protect off-duty use or prohibit reliance on metabolite testing, with exceptions for safety-sensitive roles and federal contractors.
  • Restrictive covenants — enforceability follows the state where the employee works; several states ban them for some or all workers, impose wage thresholds, or require advance notice before an offer is accepted. Review every covenant on relocation, because a move can void an existing agreement and, in a few states, make presenting it a violation.
  • Choice-of-law and forum clauses, which several states void as applied to their residents.
  • Arbitration agreements, checked against state restrictions and against the federal carve-outs.

Phase 6 — Documents, notices, and maintenance

  • Build a core national handbook plus state-specific addenda, rather than one document attempting to describe every state — which becomes unreadable and is never current.
  • Reissue the addendum and collect a new acknowledgment when a state's law changes.
  • Deliver state notices at hire, which a growing number of states require — wage rate, sick leave, workers' compensation, whistleblower, and pay transparency disclosures.
  • Deliver postings electronically to remote employees, in a manner that is readily accessible and to which employees are affirmatively directed, in addition to physical postings at any worksite.
  • Confirm anti-discrimination statute coverage, which at the state level frequently applies at lower headcount thresholds and covers additional protected characteristics than federal law.
  • Confirm state WARN obligations, which apply at lower thresholds and with longer notice periods than the federal act.
  • Confirm monitoring and recording notice or consent requirements, including all-party consent recording states.
  • Maintain a legislative tracking process — a quarterly review of the approved states, and a January sweep of minimum wage and salary threshold changes.
  • Run an annual reconciliation of work locations against registrations, coverage, and addenda.

Common mistakes

  • Not knowing where employees actually work, which makes every other item impossible.
  • Registering after the first paycheck, which produces penalties and, in some states, personal liability.
  • Assuming the home-state workers' compensation policy covers a relocated employee.
  • Paying only weekly overtime in a daily-overtime state.
  • Applying one exempt salary threshold across states with different ones.
  • Wage statements in the payroll provider's default format, which frequently fails several states' content requirements.
  • Ignoring expense reimbursement obligations for remote employees.
  • Posting a national remote role without a salary range.
  • Enforcing a non-compete against an employee who relocated to a state that voids it.
  • Leaving a state without deregistering, and accruing penalties for unfiled returns.
