# Deprecation of the `ProductVariant.taxCode` field

As of Admin GraphQL API version `2025-10`, we are deprecating the `taxCode` field from the `ProductVariant` object. This change is part of the Avalara AvaTax app deprecation and will affect how you handle tax classification for product variants.

The `taxCode` field on `ProductVariant` objects will not be available in future API versions. If your app currently relies on this field for tax calculations or reporting, you must update your implementation before the field is fully removed.

## Why We're Making This Change

We are deprecating the `taxCode` field because the Avalara AvaTax app, which powered this functionality, is being discontinued. **This field applies only to the stores that have the Avalara AvaTax app installed.**

## What You Need to Do

If your app uses the `taxCode` field, you should:

1. **Audit Your Current Implementation**: Identify where your app reads or writes the `taxCode` field.
2. **Update Your GraphQL Queries**: Remove references to the `taxCode` field from your queries and mutations.
3. **Test Thoroughly**: Ensure your app continues to function correctly without the deprecated field.

## Timeline

The `taxCode` field will continue to return data through API version `2025-10`. However, you should migrate away from it as soon as possible, as future API versions will not include this field.
