Reporting preparation, not filing advice

OSS and IOSS reporting

VAT Engine connects committed supply-event data, registrations, thresholds, exchange-rate normalization, and review states to help teams prepare VAT reporting work.

What this helps you do

Surface missing evidence and produce structured review outputs before an accountant or responsible business user files a return.

  • OSS threshold monitoring and registration-aware views.
  • Union OSS and IOSS preparation workflows with explicit exclusions and warnings.
  • Immutable return/export snapshots after locking.
  • VAT Engine does not submit returns or decide legal filing obligations.
