The Tax Compliance & Rates Engine is a build-to-order Magento 2 / Adobe Commerce extension that replaces brittle, overlapping tax-rate tables with clean, region-isolated rule sets for GCC VAT, EU VAT, US sales tax, and India GST. ECOSIRE engineers it against your exact store topology — websites, store views, customer groups, product tax classes and shipping origins — then installs and supports it on your own Magento install.
Region-isolated rule sets so GCC VAT (5%), EU VAT (per-member-state), US sales tax (state/county/city) and India GST (CGST/SGST/IGST) never bleed into one another
Custom tax calculator registered via di.xml preference against Magento\Tax\Api\TaxCalculationInterface, leaving core checkout unpatched
Address-based rate determination resolving billing/shipping country, region, postcode and shipping origin to the correct jurisdiction
Tax-exempt handling driven by validated customer attributes and customer groups (e.g. verified VAT/TRN, resale certificate flags)
EU intra-community and GCC reverse-charge logic that zero-rates qualifying B2B orders and records the liability shift
Return-ready reporting: admin grid plus CSV/PDF exports aggregating net/tax/gross by jurisdiction and filing period
This is not an instant Adobe Commerce Marketplace download. It is a bespoke module delivered under app/code/Ecosire/TaxComplianceEngine, wired through standard Magento mechanics: a custom tax calculator registered against Magento\Tax\Api\TaxCalculationInterface, plugins/interceptors on Magento\Tax\Model\Calculation, observers on quote and order events, and a di.xml preference layer so core checkout is never patched directly. Rates are resolved by billing/shipping address through a pluggable rate provider, with tax-exempt and EU/GCC reverse-charge handling driven by validated customer attributes (e.g. VAT/TRN numbers).
Reporting is return-ready: a dedicated admin grid and exportable datasets (CSV/PDF) aggregate net, tax and gross by jurisdiction and period, mapped to the fields your VAT/GST filing actually needs. Output exposes service contracts and GraphQL/REST endpoints so headless storefronts (PWA Studio, Hyvä, custom frontends) and external accounting tools consume the same numbers checkout used.
Everything respects Magento conventions you already rely on: admin ACL for every controller and report, cron for scheduled report rollups, multi-store and multi-currency awareness, and clean integration hooks so it feeds ECOSIRE e-invoicing modules (ZATCA, FTA, Peppol) without duplicate tax logic. You get the full source, a migration plan from your current tax config, and ongoing support — honestly delivered to order, not a black box.
Sells across jurisdictions with different VAT/sales-tax regimes and is tired of overlapping Magento rate tables producing wrong tax at checkout. Wants region-isolated rules that are provably correct per market.
Owns the VAT/GST returns and audit trail. Needs report exports that map directly to filing fields, correct reverse-charge and exemption handling, and confidence that the storefront and the books agree.
Maintains a multi-store Adobe Commerce or Open Source build and refuses core hacks. Wants tax logic delivered as a clean module via di.xml, plugins, service contracts and GraphQL/REST — with source they can audit and extend.

No. This is a build-to-order extension. ECOSIRE develops it for your specific Magento store, then installs and configures it on your environment. You receive the full module source under app/code, not a one-click Marketplace package, because the value is in correctly modelling your jurisdictions, tax classes and customer groups.
A typical engagement runs about 2 to 4 weeks depending on how many regions you operate, the complexity of your tax classes and reverse-charge rules, and whether headless/GraphQL or e-invoicing integration is in scope. We confirm a firm lead time after a short scoping call, deliver to staging first for sign-off, then schedule production install. Rush timelines can sometimes be accommodated.
Delivery includes a warranty period for defect fixes. Beyond that, an optional ongoing support and maintenance plan covers Magento/Adobe Commerce version-compatibility updates, rate-table or rule adjustments when regulations change, and assistance with new markets. Because you hold the source, your own team can also maintain or extend it; we are not a lock-in black box.
Yes. The module uses standard service contracts, di.xml preferences, plugins and observers that run on both editions. On Adobe Commerce we can additionally account for B2B features such as shared-catalog and company-account tax classes where you are licensed for them. We target your exact Magento 2 minor version and PHP version.
Reverse charge for qualifying EU intra-community and GCC B2B orders is applied from validated customer attributes (such as a verified VAT/TRN number), zero-rating the order while recording the liability shift for reporting. Exemptions are driven by customer group and certificate flags. Line-level tax data is exposed through integration hooks so it can feed ECOSIRE e-invoicing modules (ZATCA, FTA, Peppol) without re-implementing tax logic.
