Tax line mapping
The Tax Line Mapping tab is currently a browser-local preparation worksheet. It starts with an entity-specific set of example account-to-form-line mappings.
Manage mappings
Open Tax & Export > Tax Line Mapping and choose the entity type. Add Mapping appends a local draft row with a placeholder account and form line. The page stores the rows in browser localStorage for the active tenant, tax year, and entity type.
The current committed page does not let you select a real ledger account, edit or remove an existing row, or save the worksheet through GraphQL. These local rows do not update account tax-line overrides and do not control the server-generated tax packet.
The Working Trial Balance may separately display tax-line labels returned by the reporting query. Treat those labels and this worksheet as preparation aids, confirm mappings with your tax preparer, and do not assume the local draft changed the books or export service.
