US sales tax is a moving target: 14,000+ jurisdictions, rooftop-accurate rates, product-specific taxability, and economic nexus thresholds that change per state. WooCommerce core gives you flat manual tax tables — fine until you cross a nexus threshold and have to track, collect, and file in states you've never sold into before.
Real-time rooftop-accurate US sales-tax calculation via the TaxJar API, applied at cart and checkout through WooCommerce's native tax filters so the displayed rate equals the recorded order rate
Coverage of 14,000+ US state, county, city, and special-district jurisdictions, including origin-based vs destination-based sourcing per state
Economic nexus dashboard inside wp-admin showing per-state transaction and revenue thresholds, with approaching/exceeded status pulled from TaxJar
AutoFile automated sales-tax return filing through TaxJar for the states you enroll, removing manual return preparation
WooCommerce product tax-class to TaxJar tax-category mapping (e.g. clothing, SaaS, digital goods, food) for correct product-level taxability
Order transaction sync to TaxJar on a scheduled job — WP-Cron by default, or a hardened server-side cron we configure to avoid missed syncs on low-traffic stores
The TaxJar Sales Tax & AutoFile Connector for WooCommerce bridges your store to the TaxJar API so tax is calculated at checkout from the destination rooftop address, not a guessed zip-level rate. We hook into WooCommerce's tax calculation pipeline (woocommerce_calculate_totals, the cart/checkout tax filters, and the order-line tax meta) so the rate shown to the customer is the rate that gets recorded on the order — including on the HPOS / custom order tables if your store has them enabled.
This is an honest build-to-order plugin. It is not an instant marketplace download. After purchase, ECOSIRE builds, installs, and configures the connector directly on your WordPress site: we register your TaxJar API token securely in wp-admin, map your WooCommerce product tax classes to TaxJar tax categories, validate your origin/nexus addresses, and confirm calculations against live test orders.
The economic nexus dashboard surfaces TaxJar's per-state threshold tracking inside wp-admin so you can see where you're approaching or have crossed a registration obligation. AutoFile then automates the actual return filing through TaxJar for the states you've enrolled — transactions sync via a scheduled job (WP-Cron, or a real server cron we configure for reliability) so TaxJar always has current order data.
Every build is version-locked to your WooCommerce and WordPress versions, tested against your theme and active tax-affecting extensions, and handed over with documentation. Ongoing support, compatibility updates, and TaxJar API changes are covered by ECOSIRE.
A US merchant who recently moved off a hosted platform to WooCommerce and now has tax obligations in several states. They need calculation and filing reunified in one place without learning a new tax stack.
A direct-to-consumer WooCommerce store whose sales volume is tripping economic nexus in new states each quarter. They need automated threshold monitoring and hands-off AutoFile so compliance keeps pace with growth.
A finance or ops owner spending hours each filing period exporting orders and keying returns by hand. They want order data to flow into TaxJar automatically and returns filed without manual prep.

This is a build-to-order plugin, not an instant download. After purchase we schedule a short kickoff to collect your TaxJar API token, nexus states, and catalog tax classes. Typical delivery is 5–10 business days depending on catalog size and the number of nexus states, including installation on your site and live test-order validation before go-live. Complex multi-store or multisite setups may take longer — we confirm a firm timeline at kickoff.
ECOSIRE supports the connector after launch. We cover compatibility with your WooCommerce and WordPress updates, changes to the TaxJar API, and bug fixes. If WooCommerce ships a breaking change to its tax pipeline or HPOS, or TaxJar revises an endpoint, we update your build. Support requests are handled directly by our engineering team — you're not filing tickets into a generic marketplace queue.
Yes. This connector integrates your WooCommerce store with TaxJar — it does not replace TaxJar. You provide an active TaxJar account and API token; AutoFile filing is a TaxJar service you enroll in per state. We handle all the WooCommerce-side engineering, configuration, and validation so the two systems work together correctly.
Yes — that's exactly why it's build-to-order. We test the connector against your active theme, your other tax-affecting extensions, and your storage mode (legacy post-based orders or High-Performance Order Storage). WPML and WordPress multisite are supported; multisite and multi-currency setups are scoped at kickoff since per-site tax configuration affects the build.
Considerably more accurate. WooCommerce core uses static, manually maintained tax-rate tables that you have to keep current per jurisdiction. This connector calls TaxJar in real time using the customer's rooftop destination address, so it resolves the correct state, county, city, and special-district rates across 14,000+ jurisdictions and applies product-level taxability — none of which WooCommerce core does on its own.
