How to Verify Jurisdiction Codes Returned by the Symmetry Tax Engine API

Introduction

This article explains how to verify jurisdiction codes returned by the Symmetry Tax Engine API to ensure accurate tax calculation for each employee. Correct jurisdiction codes are essential for compliant payroll tax processing across federal, state, and local levels.

Understanding Jurisdiction Codes

Jurisdiction codes identify the specific tax jurisdictions applicable to an employee based on their address or Payroll Point information. They are used to determine the correct federal, state, and local tax calculations.

Verifying Jurisdiction Codes

To verify the jurisdiction codes returned by the Symmetry API, follow these steps:

1. Access the latest Symmetry reference documentation or jurisdiction lookup tools provided in our developer portal.
2. Cross-check each jurisdiction code returned by the API against the official codes in the reference materials.
3. Confirm that the jurisdiction codes align with the employee's physical address data (including state, county, city, and school district information).
4. Use Payroll Point address geocoding to resolve ambiguous or multiple jurisdiction results if necessary.
5. If any jurisdiction code appears incorrect or missing, use the lookup tools to identify possible alternative codes or report the issue to Symmetry support.

Best Practices for Jurisdiction Verification

• Regularly update your jurisdiction reference data by syncing with Symmetry API updates.
• Implement automated checks in your integration workflows to validate jurisdiction codes against Symmetry's official list.
• For multi-state or multi-jurisdiction employees, carefully verify all applicable codes to ensure comprehensive tax coverage.
• Contact Symmetry support immediately if discrepancies persist after verification.
