この製品について
Most US merchants outgrow Magento's built-in tax tables fast. Native tax rates are flat zip-code rules that miss rooftop-level jurisdiction boundaries, ignore economic nexus thresholds, and leave you reconciling returns by hand. This extension replaces that guesswork by wiring your store directly into the TaxJar API.
ECOSIRE builds the module as a clean, namespaced package under app/code/Ecosire/TaxJar, following Magento 2 best practices: a Magento\Tax\Api\TaxCalculationInterface plugin/interceptor (via di.xml) that calls TaxJar at quote-collect time, observers on sales_order_invoice_register and sales_order_creditmemo_save_after to push transactions and sync partial and full refunds (credit memos), and a cron job that polls nexus exposure. Calculation results are cached to keep checkout fast and to respect TaxJar rate limits, with a graceful fallback to your configured backup rate if the API is unreachable.
You get a dedicated admin configuration section with proper ACL resources (Ecosire_TaxJar::config), so staff see only what their role allows. Map Magento tax classes to TaxJar product tax categories (e.g., clothing, SaaS, food) so exempt and reduced-rate items calculate correctly. An admin grid surfaces economic nexus alerts as your sales approach each state's threshold, and a reporting view assembles the figures you hand to your filing process or accountant.
This is not an instant Adobe Commerce Marketplace download. It is custom-built to fit your exact Magento Open Source or Adobe Commerce version, theme, and checkout flow, then installed and verified on your environment. You bring a TaxJar account and API token; we handle the engineering, the install, and the post-launch support. Works with both REST and GraphQL checkout front-ends.

これは誰のためのものですか
US SMB store owner
Runs a growing Magento Open Source store selling into multiple states, wants accurate sales tax and nexus alerts without the cost or complexity of an enterprise tax engine.
Finance / accounting lead
Owns sales-tax filing and reconciliation, needs clean per-jurisdiction reports and credit-memo accuracy so returns prepared in TaxJar match what the store actually collected.
Magento developer or agency
Maintains a client's store and wants a clean, upgrade-safe TaxJar integration built with plugins, observers, and ACL — not a core hack — that they can support long-term.

TaxJar Sales Tax Automation に関するよくある質問
How long until the extension is delivered and live on my store?
Because this is built to order for your specific Magento version, theme, and checkout, typical delivery is about one working week from kickoff and TaxJar account access. We install and verify on a staging copy first, then schedule the production cutover with you. Complex multi-store or headless setups may take longer; we confirm the timeline in writing before starting.
What do I need to provide before you start?
An active TaxJar account with an API token (TaxJar's own subscription is separate and billed by TaxJar), admin and SSH/deploy access to a staging environment, and your list of nexus states and product tax treatment. We handle all the Magento engineering and installation.
Do I get ongoing support and updates after launch?
Yes. Every build includes a post-go-live support and bug-fix window agreed before we start. After that, we offer optional retainer support for Magento and Adobe Commerce version upgrades, TaxJar API changes, and new feature requests. Because the module is namespaced and upgrade-safe (no core edits), most Magento patch updates need no rework.
Will this work on Adobe Commerce as well as Magento Open Source?
Yes. The module targets the same Magento\Tax service contracts and APIs present in both Adobe Commerce and Magento Open Source, and we build against your exact version. It also works with headless front-ends that checkout via GraphQL, since tax is resolved server-side at quote collection.
Is this just the official TaxJar Marketplace extension repackaged?
No. This is an ECOSIRE-engineered integration built and supported by us against the TaxJar API, tailored to your store. It is not an instant Adobe Commerce Marketplace download. If you prefer an off-the-shelf listing, you can buy one separately; our value is the custom fit, the install, and the direct support.
Does it handle refunds and partial returns correctly for tax reporting?
Yes. An observer on sales_order_creditmemo_save_after pushes both full and partial credit memos to TaxJar, so refunded tax is reflected in your transaction history and your filing-prep reports stay accurate rather than overstating collected tax.
