Enhance tax calculation with dual currency fields

Executive summary:

• Additional currency fields introduced.
• Enhance reporting in merchant's accounting currency.
• Beneficial for tax partner apps and billing accuracy.

What changed

With API version 2026-01, Shopify introduces additional fields to the tax_summaries/create webhook and tax calculation requests for tax partner apps. These new fields include currency-specific amounts, providing clarity in both shop currency and presentment currency. The objective is to enable accurate reporting and tax calculations in the merchant's preferred currency, ensuring display remains consistent for customers.

Why it matters

This enhancement is especially useful for enterprise merchants using Shopify Plus who operate with multiple currencies. It prevents discrepancies between the amounts displayed to customers and those used in backend accounting, reducing manual adjustments and potential errors.

Role-specific impact

• Marketers: Enhance campaign pricing accuracy across currencies.
• Developers: Streamline data parsing by leveraging the new MoneyBag structure.
• Store admins: Easily reconcile amounts between different currency settings and reports.

Use-case example
