etax4apps. The Oracle Tax Engine, correctly configured.
Tax determination is handled by the Oracle Tax Engine. The level of pre-configuration differs per Oracle product and is assessed per customer. etax4apps is the 4apps service that configures it correctly, so that each transaction receives the appropriate tax treatment in every jurisdiction. itax4apps then reconciles, files, reports and exchanges what the engine has determined.
Oracle determines. itax4apps proves.
A single, traceable chain from the transaction in Oracle to the final compliance output. No middleware and no adjustments: every figure can be traced back to the source data in Oracle.
Transaction
An AR, AP or intercompany transaction is posted in Oracle Fusion Cloud ERP or Oracle EBS.
Tax engine

Why it matters for ViDA
Under ViDA, every intra-EU invoice becomes an e-invoice that is reported to the tax authority within days. A wrong tax code is no longer corrected in next month's return; it is visible immediately. Correct tax determination at the source, in the Oracle Tax Engine, is the first step to being ViDA ready.
