Tax-rate mapping
What a renamed WooCommerce tax rate does to reports
Renaming a current tax-rate row can change what an administrator sees without rewriting every historical order line.
Inspect the source record
Compare the stored label on a past order's tax line with the current rate-table label and ID. Record which value came from which source.
Build a focused report
Keep the verified TaxPack mapping attached to the rate ID and generate a short report that spans an order before and after the rename.
Read the result
The tax-line CSV preserves stored labels while the reporting type follows the explicit ID mapping, making the discrepancy reviewable.
A concrete example
A rate renamed from Sales tax to HST in October does not retroactively establish that every older use of that ID was HST.
Avoid this mistaken conclusion
Do not rewrite a historical classification based only on today's label. The order record and configuration history matter.
