# exemptionCertificate

query · in the family [Exemption certificate](/reference/exemption-certificate/)

## What it does

Look up one record — a customer’s tax-exemption certificate.

A ExemptionCertificate by id, within the caller's OWN org-group family; requires authentication. A cross-tenant id reads as null (not-found) AND trips the rootId tripwire server-side.

## What happens

Reads only — changes nothing.

## 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:exemptionCertificate`

## Arguments

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

## Returns

[ExemptionCertificate](/types/ExemptionCertificate/) — A tax-exemption certificate — a captured legal document: a valid in-scope cert ZEROES tax at sale for its covered jurisdictions/categories (the calc consumes it; at-USE validity = status active ∧ not past expiresAt ∧ scope match — CONFLICT/EXPIRED per SPEC_ERRORS). Parent = the org group, FIXED AT BIRTH (the / customer host is a later REF, never a reparent). Capture is INLINE. The capture is IMMUTABLE except caption/code/docRef — correct anything else by revoking and re-capturing. active → expired is SCHEDULED; revoke and doom are the caller ops.
