Understanding Shopify Tax Plans and Sidr Tax Compatibility

When setting up sales tax management for a Shopify store, it is important to understand how Shopify’s own tax plans differ and how they integrate with Sidr Tax services. This helps ensure your setup is both cost-efficient and fully compliant.

Shopify tax plans: Paid Shopify Tax, Shopify Basic Tax, and Shopify Manual Tax

Manual Tax in Shopify is a configuration setting for merchants who prefer—or are required—to set their own tax rates rather than using Shopify’s automated tax engine. When you use manual tax settings, you are responsible for the accuracy of the rates. Here is how it functions:

• Manual Entry: You specify the tax rates for each state, province, or country manually within the Taxes and duties section of your admin.
• Base Taxes: You can set a base rate and then determine how sub-region taxes (like state or county) interact with it.

For more details on how to set up manual tax rates, see Shopify's Manual Tax article.

Shopify Basic Tax Plan includes a built-in tax engine. This plan automatically calculates sales tax based on store location, customer location, and product taxability settings. It handles tax rate determination and calculation in real time during checkout. According to Shopify: As of July 1, 2025, Basic Tax will no longer be available to new merchants selling in or to the United States. Merchants already using Basic Tax as their tax service in the United States can continue to use it without interruption. Basic Tax continues to be available to new and existing merchants in supported regions outside the United States.

Paid Shopify Tax Plan introduces several advanced tools—such as rooftop-level calculation accuracy, automated product categorization, and real-time nexus monitoring—it is important to remember that these are primarily software enhancements.

Sidr Tax’s Role and Integration

Sidr Tax is not a tax engine. Instead, it connects with Shopify’s existing tax engine to import accurate tax data. Once that tax data is in place, Sidr Tax provides specialized services that Shopify’s plans do not directly handle, such as:

• Sales tax registration and account setup across multiple states
• Nexus monitoring and reporting for physical and economic presence
• End-to-end sales tax filing and remittance support

Sidr leverages Shopify’s tax calculation capabilities but focuses on the compliance side—ensuring merchants meet their state-level obligations and jurisdictional breakdowns properly.

While Paid Shopify Tax Plan provides the tools to help you manage taxes yourself, our service offers a complete compliance partnership. The differences are obvious:

• Accuracy with a Human Touch: All our filings are manually inspected by our internal team for accuracy.
• Beyond "Help": Shopify’s paid plan offers "filing help" (tools for you to use), whereas we provide Filing Execution (we do the work for you).
• Reliable Support: Instead of waiting on a general support queue, you get direct access to our tax specialists via phone, email, and live chat.
• Better Value: We offer transparent, competitive and reliable pricing that doesn't penalize your success.

Optimizing Sidr Tax with Shopify’s Tax Plans

As Shopify has updated its tax offerings, all new merchants selling in the US now use a paid Shopify Tax tier. Sidr Tax is fully compatible with all Shopify Tax plans, ensuring your data flows seamlessly from your storefront to your tax filings.

However, to ensure the most cost-effective and reliable compliance setup, we recommend:

• Avoid Feature Redundancy: While Shopify’s native tax plans now include automated "filing help" and reporting, these are self-service tools. Combining them with Sidr Tax’s professional filing can result in overlapping fees for the same functionality.
• Expert Support vs. Automated Tools: Shopify’s tax plans provide the data, but Sidr Tax provides the expertise. While Shopify offers platform-based help, our team provides dedicated phone, email, and live chat support to handle the complexities of nexus and registration that automation often misses.
• The Best Configuration: We recommend using the standard Shopify Tax tier for its essential calculation engine and relying on Sidr Tax for the "heavy lifting"—including nexus tracking, registration, and guaranteed accurate filings.
