Important research findings
Saudi and South African official sites contain discoverable older guidance that must not be mistaken for current rules. Brazil has official reform documentation, but an old index URL moved. Canadian coverage requires provincial validation. US references here cover only California and Texas, not all states.
Using these references
Read the guidance for your location, transaction type and date. A source-check date is not a rule's effective date, and an official link does not establish eligibility. Where a document could not be verified, that is a limitation of our research, not a statement that the tax authority has left the rule undecided.
