# Customer Tax ID Collection Gap Check

## Inputs
Customer export, the tax ID field, the jurisdictions where collection is required and the invoice schedule.

## Workflow
1. List customers in jurisdictions where a tax ID is required.
2. Flag records with an empty or invalid-format tax ID.
3. Exclude customers with a documented exemption.
4. Return the gap list without changing tax settings or billing.

## Output contract
Customer | jurisdiction | tax ID present | format valid | exemption | action | reviewer

## Fictional acceptance test
Fictional export: 22 customers in scope; 19 have valid IDs, 2 are empty and 1 fails the country format. Flag 3 records.

## Review gates
Re-check the jurisdiction rule for each customer address, not the billing contact's country. Never invent a tax ID.
