Tax Categories

A tax category is a named group of tax rates. It is the bridge between your products and the individual tax rates that determine how much tax they're charged: each product is assigned a tax category, and the category carries the set of tax rates that apply. This menu mirrors the admin Settings → Taxes → Tax Categories screen.

How tax categories fit together

Tax rates (under Settings → Taxes → Tax Rates) are the individual rate rows — each one is a percentage that applies under certain conditions (country, state, zip, etc.). A tax category bundles one or more of those rates under a single name. You then assign the category to a product, and at checkout the right rate from the category is applied to that product.

So the relationship is: products → tax category → tax rates. Editing a category changes which rates apply to every product that uses it.

Fields

Field	Meaning
code	A unique machine code identifying the category (used internally and when assigning the category to products).
name	The human-readable display name shown in the admin.
description	A free-text description of what the category is for.
taxRates	The tax rates attached to this category, exposed as a field-selectable connection — select taxRates { edges { node { _id identifier taxRate } } }. Each node carries the rate's _id, identifier, and taxRate (the percentage). This connection is detail-only — it resolves on the single-category query but has empty edges on the listing.

Creating, updating, and deleting

• Create — supply code, name, description, and a non-empty taxrates list of existing tax-rate ids. A tax category cannot be created without at least one rate attached.
• Update — re-syncs the category. The taxrates list you send replaces the current set (rates not in the list are detached, new ones are attached). It is required and must be non-empty.
• Delete — removes the category, but only if it has no tax rates attached. A category that still has rates attached is refused. Because both create and update require a non-empty taxrates list, a category becomes deletable only once it has no attached rates.

Delete guard

You can't delete a tax category that still has tax rates attached — the request is refused. The category must be empty of rates before it can be removed.
