About OxAlpha Tax

The product

OxAlpha Tax is an autonomous tax assistant for Israeli businesses of every legal form — exempt dealers, registered dealers, small dealers, and companies. It replaces the traditional bookkeeping workflow with five cooperating engines: financial source connectivity (Bit, PayBox, and CSV fallback in this build), automated transaction classification with confidence scoring, tax calculation from official effective-dated 2026 parameters, compliant document generation including Israel Tax Authority allocation numbers, and a filing pipeline that physically cannot submit anything without an explicit human approval event.

The signature idea is the side wallet: every incoming payment automatically reserves a configurable slice for tax, so liabilities are pre-funded by the time they come due. A lost-money radar sweeps connected sources for duplicate charges, unclaimed deductible expenses, and recoverable platform fees, and quantifies every finding in shekels.

How it is built

All legislation lives in versioned, effective-dated parameter tables rather than hard-coded rates, so annual CPI updates and law changes are data operations. The tax engine is a set of dependency-free pure modules covered by unit tests with exact hand-verified expected values. The full architecture specification — database schema, API design, security checklist, and deployment plan — ships alongside the code in TAX_ASSISTANT_SPEC.md.

This deployment is a demonstration: sources are simulated, documents are not actually filed with any authority, and all data stays in your own browser. See the Terms for scope, data handling, and AI-build disclosure.
