# EditTaxRegistrationInput

input type

Edit-input for a TaxRegistration. Every field optional, at least ONE required; supplied fields REPLACE, omitted fields are preserved (no clearing semantic). The PAIR (organizationId/jurisdictionId) is NOT editable (IMMUTABLE at birth — the identity AND its uniqueness marker; re-register = create + doom, T-h).

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `caption` | [String](/types/#scalars) | no | No further notes. |
| `registrationNumber` | [String](/types/#scalars) | no | The corrected permit number (corrections are real). |
| `code` | [String](/types/#scalars) | no | No further notes. |
