TaxRate

object type

A tax rate cell — ONE effective-dated (jurisdiction × category × window) cell of OUR canonical rate tables, carrying BOTH the rule outcome (treatment) AND the rate (integer parts-per-million — 6.625% = 66250). SHARED-CANONICAL + READ-ONLY on the wire (the ruling rides down from the tree; writes are kit-channel — the seed slice). A DATED_SCHEDULE: half-open [startAt, endAt) windows, splice-normalized PER (jurisdiction × category) sub-schedule — the record set IS the full rate history; supersede, never rewrite. exempt/zero_rated cells price at 0 (zero_rated keeps input credits — the distinction feeds remittance). compound = tax-on-tax; combined = the HST marker (this rate REPLACES the ancestor stack). An optional threshold scopes the rule to unit prices STRICTLY BELOW it (minor units of the country currency — the BC childrens-clothing shape).

Fields

Field	Type	Notes
`id`	ID `ID!`	The record’s id — a UUID the platform assigned when the record was created; every reference to this record uses it.
`sysId`	String `String!`	The GLOBAL-namespace human-facing system id (TX-…, account-wide, like the Account's).
`type`	String `String!`	The kind of record — always `TaxRate` here.
`caption`	String `String!`	The record’s display name — what people see it called.
`status`	String `String!`	The FSM state: active \| doomed.
`parentId`	ID `ID!`	The owning TaxJurisdiction; for a TaxRate parentId === rootId (the shared-canonical anchor, T-c) — always present.
`rootId`	ID `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 `String!`	When the record was created, as a UTC timestamp.
`updatedAt`	String `String!`	When the record last changed, as a UTC timestamp.
`revisionNum`	Int `Int!`	How many times this record has been edited; the first save is 0.
`revision`	ID `ID!`	The OCC revision token — supply it on every mutation of this record; rotates on every write.
`refCaptions`	RefCaption `[RefCaption!]!`	The server-composed captions of this record's declared references (the referenced-caption rule) — one row per referenced id; see RefCaption.
`category`	TaxCategory `TaxCategory!`	The taxed category. One sub-schedule per (jurisdiction × category). IMMUTABLE.
`treatment`	TaxTreatment `TaxTreatment!`	The rule outcome. IMMUTABLE — supersede to change.
`ratePpm`	Int `Int!`	The rate in integer parts-per-million (0..1000000; 6.625% = 66250). 0 ⟺ zero_rated/exempt. IMMUTABLE.
`compound`	Boolean `Boolean!`	Tax-on-tax: applies over the base PLUS prior stacked tax. IMMUTABLE.
`combined`	Boolean `Boolean!`	The HST marker: this rate REPLACES the ancestor-chain stack. IMMUTABLE.
`thresholdMinorUnits`	Int	Optional: the rule applies to unit prices STRICTLY BELOW this (minor units of the jurisdiction country currency); at-or-above falls through to the node standard-category cell. IMMUTABLE.
`startAt`	String `String!`	The window start (inclusive; UTC ISO-8601). IMMUTABLE.
`endAt`	String `String!`	The window end (EXCLUSIVE; UTC ISO-8601; always present — far-future = the standing rate). Moves ONLY via the system splice trim.
