Sales Tax Configuration Guide

Overview

This guide explains how sales tax is handled across different sales channels and return scenarios. Understanding these concepts is crucial for proper tax reporting and reconciliation.

Key Concepts
  • Tax calculations occur at the line item level
  • Returns can create tax rate mismatches between stores
  • Web orders use different tax calculation methods than in-store orders

Basic Tax Structure

Line Item Tax Details

Each line item in ORDERDETAIL stores:

  • Individual tax amounts (tax1, tax2, tax3)
  • Tax definition ID (taxdefid)
  • Line total amount (linetot)

Store Tax Configuration

Current implementation uses a 1:1 mapping:

Store ID = Tax Rate Code = Tax Definition ID
Example: Store 101 → Tax Rate 101 → Tax Definition 101
caution

This simple mapping system may need revision if more complex tax scenarios are required in the future.

Return Processing

How Returns Affect Numbers

When a return is processed:

  • ✅ Salesperson's sales volume is adjusted down
  • ❌ Store's sales volume remains unchanged
  • 💰 Customer receives exact tax amount from original purchase

Cross-Store Returns

Returns processed at a different store than the original purchase create reporting complexities:

  1. Different tax rates between stores create reconciliation variances
  2. Original store information may be lost for non-taxed items
  3. Tax liability accounts require manual adjustments
Tax Rate Mismatches

Cross-store returns with different tax rates will create variances in tax reporting. These variances are expected and should be monitored.

Web Orders

Tax Calculation Flow

  1. Initial order:

    • Avalara calculates tax through Shopify
    • System uses these calculated values
  2. Order modifications:

    • System recalculates using ZIP code-based tax rates
    • Creates potential mismatch with Avalara

Reconciliation Options

  • Generate report of modified web orders
  • Manually adjust values in Avalara
  • Best for low volume of changes

Option 2: Full Replacement

  • Export complete ORDERDETAIL data for web sales
  • Replace Avalara data entirely
  • Provides better audit trail but requires more maintenance
Recommended Approach

For most scenarios, Option 1 (Manual Adjustment) is preferred due to:

  • Lower operational overhead
  • Reduced risk of data synchronization issues
  • Simpler implementation

Troubleshooting

Finding Original Store Information

To trace original store for returns:

orderdetail.taxctrlid → odreturns.pretaxctrl → orderdetail.branchid

Common Issues

  1. Missing original store information for non-taxed items
  2. Tax rate mismatches between original and return stores
  3. Avalara/Shopify synchronization discrepancies

Additional Resources

  • Contact technical support for assistance with tax definition setup
  • Review accounting documentation for G/L reconciliation procedures
  • Consult Avalara documentation for web order tax calculations
note

Always test tax configuration changes in a staging environment before applying to production.
