Managing payroll across multiple states isn’t just complicated—it’s a high-stakes puzzle involving compliance, tax codes, and ever-changing labor regulations. In this insightful session, Laura Detsch, Tax Specification Compliance Manager, and Lauren DeBisschop, Content Marketing Manager at Greenshades, shared critical strategies for staying compliant in a multi-jurisdictional environment.
Together, they walked through the four core challenges of multi-state payroll and introduced practical "connection keys"—solutions designed to make the process more manageable.

Webinar Recap: Key Takeaways
The more states your workforce spans, the more regulatory complexity you face. From varying tax rules to overlapping local ordinances, each jurisdiction adds a layer of risk to your payroll processes. Greenshades offered five essential best practices that can help simplify operations and ensure compliance.
Assign home and work addresses accurately
Understanding where employees live and where they actually perform their work is foundational to determining which laws apply and how taxes should be withheld.
Set alerts for tax and wage law changes
Because wage and leave laws can shift mid-year and differ by role or jurisdiction, it’s essential to monitor updates—or use systems that track them for you.
Standardize onboarding by jurisdiction
Ensure every new hire completes the correct forms based on their state and city. Building a standardized onboarding process improves accuracy and reduces delays.
Use timekeeping tools that capture location
Pay rules are often dependent not only on how long someone worked—but also on where. Accurate timekeeping by location is crucial.
Audit your process quarterly
Regular reviews of tax rates, registrations, and wage calculations can help catch errors early and prevent costly corrections.
Core Challenges and Strategies: Solving the Puzzle
The heart of the webinar focused on breaking down four major compliance challenges, each paired with a key strategy for resolution.
Challenge #1: Tax Withholding Complexity
Every state has different rules, and some localities pile on their own taxes.
- Different tax rates, methods, and forms across jurisdictions
- Cities and counties may levy taxes on top of state rates
- Remote work can trigger new state registrations
- Reciprocity agreements help—but only if exemption forms are filed
Connection Key: Maintain up-to-date home and work addresses for every employee. Accurate location data is essential for proper tax withholding and registration.
Challenge 2: Tracking Time Across Jurisdictions
Time tracking becomes more complex when employees work across multiple states or locations.
- Overtime rules vary by state and even by city
- Federal baseline is 40 hours/week, but some states are stricter
- Certain states mandate paid rest or meal breaks
- You must know where work was performed—not just how long
Connection Key: Leverage time tracking systems that include geolocation or location tagging. These tools help ensure you're applying the correct wage and break rules for the right jurisdiction.
Challenge #3: Zip Code-Specific Labor Laws
Some states and cities enforce labor laws at an extremely granular level.
- Over 30 states and 60+ cities exceed the federal minimum wage
- Paid Sick Leave (PSL) and Paid Family and Medical Leave (PFML) laws vary widely
- Updates can happen mid-year and differ by role or industry
- Zip code errors can cause rejections in new hire reporting
Connection Key: Automate wage rate updates and leave accrual settings within your payroll system. This ensures employees are paid correctly based on where they work and live.
Challenge #4: Reporting, Filing, and Registration
Every jurisdiction has its own rules on registration and deadlines.
- Requirements for withholding, unemployment (SUTA), and paid leave vary
- Local tax accounts may be needed in cities and counties
- Some jurisdictions expect zero-wage filings for inactive quarters
- State-specific new hire reporting adds complexity
Connection Key: Build a comprehensive payroll calendar that includes state- and locality-specific filing dates and required forms. Staying organized is key to avoiding late filings and penalties.
Deep Dive: Additional Compliance Considerations
Beyond the core challenges, the presenters explored several advanced topics that payroll professionals need to understand as their operations grow more complex.
Reciprocity Agreements
Reciprocity agreements allow employees who live in one state and work in another to pay income tax only to their state of residence. These agreements can reduce double taxation but require proper exemption forms to be filed and retained.
Even when reciprocity is in effect, employers must still adhere to SUTA and labor law requirements in the work state. Payroll systems must be updated to reflect the appropriate withholding setup.
Local and City Taxes
Some localities impose additional income taxes on top of state taxes. These can be based on work location, residence, or both. States like Ohio and Pennsylvania have hundreds of local tax jurisdictions, making precise tracking essential.
Using a zip-code-level lookup tool or a payroll system that auto-assigns the correct codes based on address can greatly reduce errors in local withholding.
Tax Nexus and Remote Work
The concept of tax nexus determines whether a business is required to register and remit taxes in a given state. Hiring a single employee in a state—especially one working remotely—can establish nexus, triggering obligations for income tax, unemployment insurance, and more.
Understanding how each state defines nexus is vital. Even a single remote worker could bring new administrative requirements that must be tracked and fulfilled.
