Tax-rate mapping
How free and paid TaxPack share rate mappings
A store can begin with the free plugin and later use the paid edition without reclassifying every existing rate ID.
Inspect the source record
Check the mapping revision and verified rate IDs in the free edition before installing the separately distributed paid plugin.
Build a focused report
Open the paid reporting screen and confirm it reads the same mappings; generate a small comparison period before changing any classification.
Read the result
Future paid reports use the current shared mapping. Older saved paid reports retain the revision and values they had when created.
A concrete example
If a rate ID was mapped to PST in free TaxPack, a new paid report can use that mapping while an older paid snapshot stays unchanged.
Avoid this mistaken conclusion
Do not assume uninstalling an edition deletes mappings or saved records. Back up the store and treat mapping changes as deliberate revisions.
