Global Tax Decision Engine

Rule-based tax decisions for cross-border goods and services — EU, Switzerland and third countries in one canonical model.

Start workspace View demo

One global decision layer instead of country-specific legacy logic.

Dynafis separates the tax decision, evidence and output format. The engine evaluates supplier and customer country, B2B/B2C status, supply type, fixed establishment, registrations, goods movement and Incoterms. Uncertain national exceptions are explicitly routed to review.

249 ISO countries and territories in one registry; unmaintained cases remain review-required
OSS/IOSS, reverse charge, triangulation, chain transactions, import and export
KSeF, EN16931 and national mapping metadata
Customs, HS code, origin and Incoterm evidence
Versioned decisions with human-review boundaries

Canonical model

Outputs are generated from a controlled invoice record with format-specific checks rather than disconnected format silos.

Audit trail

Relevant activity, findings and decisions remain traceable for evidence and accountability.

Human approval

AI can assist, flag risks and suggest corrections. Acceptance or rejection remains separately documented.

Tenant separation

Workspace, tenant and role context are evaluated server-side.

Versioned rules

Checks are linked to a format, rule reference and, where available, a version.
