Reconciliation
Investigate order tax versus summed tax lines
WooCommerce stores an event tax total and tax-line detail that should be compared when reviewing exceptions.
Inspect the source record
Open the source order and inspect its total tax and each tax line, including item, fee, and shipping components.
Build a focused report
Generate a TaxPack period containing that event and review recorded_event_tax, tax_line_total, and difference.
Read the result
A nonzero difference is preserved as a review flag rather than allocated to an invented rate or province group.
A concrete example
If an order shows CAD 9 total tax but its tax lines sum to CAD 8, the CAD 1 difference needs source investigation.
Avoid this mistaken conclusion
Do not put the unmatched CAD 1 into GST or HST simply to make the summary equal the order header.
