Handling Multi-State Workers and Local Taxes with Symmetry Tax Engine

Introduction

This guide explains how the Symmetry Tax Engine detects employee work locations and applies appropriate state and local taxes, including handling multi-state scenarios, remote work, and resolving overlapping local jurisdictions using Payroll Point geocoded address data.

Process description

Symmetry Tax Engine calculates payroll taxes by determining the tax jurisdictions based on employee address information. When employees work in multiple states or have remote work locations, the engine accurately applies federal, state, and local taxes related to those locations. It utilizes Payroll Point, our address geocoding service, to identify precise tax jurisdictions.

Prerequisites

- Accurate employee work location data, including full address, city, state, ZIP code, and if possible, latitude and longitude coordinates.

- Access to Symmetry’s Payroll Point API for geocoding addresses and tax jurisdiction retrieval.

Step-by-step instructions

1. Provide complete and current employee address information to the Payroll Point service.

2. Use the Payroll Point API to geocode each address, which returns associated tax jurisdiction codes for federal, state, county, city, and school districts.

3. For employees working in multiple states, submit each work location separately to determine applicable state and local taxes for each jurisdiction.

4. When overlapping local jurisdictions are detected (e.g., multiple cities or school districts), the engine applies rules to resolve conflicts based on precedence and the most specific match from Payroll Point data.

5. Input the returned jurisdiction codes into the Symmetry Tax Engine API to calculate payroll taxes for each location accordingly.

Tips and best practices

• Ensure address data quality to reduce “No jurisdiction found” errors from Payroll Point.
• Regularly update your Payroll Point address database to reflect latest jurisdictional boundaries and tax rules.
• Handle remote work scenarios by capturing actual employee work addresses to apply correct state and local taxes.
• Use API error handling best practices to manage cases where multiple or no jurisdictions are found, including manual review workflows.
• Consult Symmetry’s compliance updates regularly to track changes in local tax law affecting jurisdictions.

Next steps

After setting up multi-state worker location data and local tax jurisdiction detection, review sample payroll calculations for accuracy. Test edge cases such as employees with multiple work locations, recent address changes, and overlapping local jurisdictions.
