What this domain asks
The transaction-time decision that combines seller and buyer entities, registrations, locations, product or service classification, exemptions, price, currency, date, sourcing, place-of-supply, and maintained rules to produce tax treatment and evidence.
The domain should retain its own evidence, decision owner, materiality criteria, exception path, and consequence even when it shares organization identity, workflow, or technology with adjacent domains. Aggregation can support oversight; it should not erase the evidence behind different risks or operating outcomes.
Buyer questions
- Which transaction facts are mandatory before the engine can decide?
- How are products, services, bundles, discounts, shipping, and digital supplies classified?
- Can tax and business users inspect the rule content, version, reason, and override?
- How are origin, destination, ship-from, ship-to, bill-to, use, and customer evidence resolved?
- What happens when master data is missing or conflicting?
- How are retrospective corrections and affected transactions identified?

Authority context
OECD VAT/GST Guidelines
The Guidelines provide internationally agreed principles for applying VAT or GST to cross-border trade, including neutrality and destination-based taxation. They do not replace domestic place-of-supply, registration, invoice, return, or recovery rules.
Texas remote-seller rules
Texas guidance describes safe-harbor, registration, single-local-rate, marketplace, sourcing, and filing considerations for remote sellers. The taxpayer's sales, channels, locations, products, and dates determine the actual result.
Canada digital-economy GST/HST
Canada's digital-economy measures address nonresident digital suppliers, platform operators, qualifying goods, and short-term accommodation through simplified and normal GST/HST regimes. Several tests can apply to one business.

Evidence boundary
Indirect Tax Monitor provides independent market and authority research, not entity-specific tax, accounting, legal, filing, registration, or implementation advice. Technology can apply configured rules, exchange structured documents, and preserve evidence; it does not determine a taxpayer's obligations without complete facts and qualified judgment. A provider's documented capability can identify a research candidate but cannot establish buyer-specific adequacy for this domain.
