# TaxJurisdiction

object type

A tax jurisdiction — ONE node of OUR canonical jurisdiction tree (roots = countries; full local depth for the US). SHARED-CANONICAL, ruled: AT builds and maintains this data centrally; merchants REFERENCE it (TaxRegistration nexus, ExemptionCertificate scopes, the calc) and never edit it — the wire is READ-ONLY (writes are kit-channel: the US+CA seed slice). The tree is the MUTABLE treeParent pointer; regime/countryCode/currencyCode ride the COUNTRY root only (descendants inherit by walk-up).

## Fields

| Field | Type | Notes |
| --- | --- | --- |
| `id` | [ID](/types/#scalars) `ID!` | The record’s id — a UUID the platform assigned when the record was created; every reference to this record uses it. |
| `sysId` | [String](/types/#scalars) `String!` | The GLOBAL-namespace human-facing system id (TJ-…, account-wide, like the Account's). |
| `type` | [String](/types/#scalars) `String!` | The kind of record — always `TaxJurisdiction` here. |
| `caption` | [String](/types/#scalars) `String!` | The record’s display name — what people see it called. |
| `status` | [String](/types/#scalars) `String!` | The FSM state: active \| inactive \| doomed. |
| `parentId` | [ID](/types/#scalars) | The id of the record this one belongs to; a record at the top of your group names the group itself. |
| `rootId` | [ID](/types/#scalars) `ID!` | The shared-canonical listing ANCHOR — the country root's id (a root self-roots: rootId === id) / the owning jurisdiction; NEVER an org group. |
| `createdAt` | [String](/types/#scalars) `String!` | When the record was created, as a UTC timestamp. |
| `updatedAt` | [String](/types/#scalars) `String!` | When the record last changed, as a UTC timestamp. |
| `revisionNum` | [Int](/types/#scalars) `Int!` | How many times this record has been edited; the first save is 0. |
| `revision` | [ID](/types/#scalars) `ID!` | The OCC revision token — supply it on every mutation of this record; rotates on every write. |
| `refCaptions` | [RefCaption](/types/RefCaption/) `[RefCaption!]!` | The server-composed captions of this record's declared references (the referenced-caption rule) — one row per referenced id; see RefCaption. |
| `level` | [TaxJurisdictionLevel](/types/TaxJurisdictionLevel/) `TaxJurisdictionLevel!` | The depth class — a child sits STRICTLY deeper than its tree parent (skips legal: cities under states). IMMUTABLE. |
| `treeParent` | [ID](/types/#scalars) | The MUTABLE tree pointer — absent ⟺ a country root. Moves stay in-country. |
| `regime` | [TaxRegime](/types/TaxRegime/) | COUNTRY ROOTS ONLY: sales_tax (rates STACK down the chain) \| vat_gst (single rate). Descendants inherit by walk-up. |
| `countryCode` | [String](/types/#scalars) | COUNTRY ROOTS ONLY: ISO 3166-1 alpha-2 (uppercase) — also the one-live-tree-per-country GLOBAL uniqueness marker value. |
| `currencyCode` | [String](/types/#scalars) | COUNTRY ROOTS ONLY: ISO 4217 (uppercase) — the currency TaxRate thresholds are minor units of. |
| `code` | [String](/types/#scalars) | Optional official geography code (ISO 3166-2 region / FIPS county / place code …) — seed-pipeline provenance; NOT an identity key. |
