# taxRate

query · in the family [Tax rate](/reference/tax-rate/)

## What it does

One tax rate row — the percentage a jurisdiction charges for a category, over time.

A TaxRate by id — SHARED canonical data: AT builds and maintains it; every authenticated principal reads it (NO tenant binding — cross-tenant reading is the point); the wire is READ-ONLY (writes are platform-channel). A missing id reads as null.

## Who may call it

Capability area: **Reading your records** — Looking up and listing the records of your organization.

- Owner
- System Administrator
- Manager
- Associate Manager
- Warehouse Associate
- Sales Associate
- Cashier
- An API key whose scope allows `api:taxRate`

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | [ID](/types/#scalars) `ID!` | yes | The id of the record. |

## Returns

[TaxRate](/types/TaxRate/) — 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).
