Background:-

Complying with tax codes, withholding requirements, and deposit schedules is already a challenge when dealing with just one state and the IRS. For multistate employers, this complexity increases exponentially, especially in a post-pandemic environment where remote work and employee mobility are common. Payroll professionals must navigate a maze of varying state rules, reciprocal agreements, residency classifications, and reporting requirements—all of which can drastically differ. Questions around which state’s taxes to withhold, where to pay unemployment insurance, and how to handle state disability deductions must often be resolved on a case-by-case basis.

Many employers mistakenly believe they can simplify the process by paying taxes and SUI to the state where an employee lives.

However, this approach often fails under audit, as most states require taxes to be withheld based on where the work is performed. Navigating multistate payroll compliance involves far more than just taxes—it also includes understanding wage and hour laws, such as varying minimum wages and overtime rules. This webinar aims to equip employers with the knowledge to handle these challenges effectively and remain compliant across all jurisdictions.
