As remote work, multi-location operations, and state-to-state employee mobility continue to expand, employers face increasingly complex tax and labor law compliance issues.

Multistate Taxation 2025 is a comprehensive training session that addresses the crucial payroll, tax withholding, wage and hour, and garnishment challenges that arise when employees live in one state and work in another—or work in multiple states simultaneously.

Led by a payroll compliance expert, this session dives into real-world solutions and best practices to help employers remain compliant, avoid penalties, and confidently manage multistate employment complexities.

Background:

Managing payroll and tax withholding in a single state is already demanding. But when employees are located across multiple states—or travel frequently between them—the complexity can grow exponentially.

From state income tax audits to conflicting wage and hour laws and garnishment rules, employers must navigate a maze of regulations, often with no one-size-fits-all solution. Making assumptions—such as withholding based on the employee’s residence alone—can lead to significant compliance risks and costly penalties.

In this session, we take a deep dive into how to correctly identify withholding obligations, unemployment insurance responsibilities, and legal exposure when managing a multistate workforce. Whether you're dealing with reciprocal agreements, temporary work assignments, or telecommuters, this webinar equips you with the knowledge to stay on the right side of compliance.
