Tax-rate mapping
Why TaxPack shows an UNMAPPED group
UNMAPPED means a stored tax line references a rate ID without a verified reporting classification.
Inspect the source record
Open the flagged event in TaxPack, note the rate ID, then inspect that ID in WooCommerce tax settings or the source order if it is historical.
Build a focused report
Assign a type only when the source evidence supports it, save the mapping, and regenerate the report to use the new revision.
Read the result
The amount remains visible in UNMAPPED until then. The group is a deliberate exception, not tax silently omitted from the report.
A concrete example
If rate ID 58 appears on three orders but has no mapping, those stored amounts remain traceable while you investigate ID 58.
Avoid this mistaken conclusion
Do not guess GST, HST, PST, QST, or RST from a rounded amount. A guessed mapping is harder to audit than an explicit unresolved row.
