Quick start

What it does. Charges US sales tax in the states where you have nexus, using the built-in rates or your Avalara or TaxJar account. While it is off, orders to the US are charged no tax.

Who can use it

  • Off until you switch it on.
  • Your plan decides whether you can use it. The module card in Settings → Modules shows Not in your plan (with See plans) or Paid add-on (with Buy add-on) when it is not included. The features list shows which plans include it.

Switch it on

  1. In your admin, open Settings → Modules.
  2. Find US Sales Tax. If it is on the Installed tab, click Enable; if not, open the Browse tab and click Install.
  3. Click Configure to change any setting below (the defaults work for most stores).

Switching it off later stops it working but keeps its data, so switching it back on picks up where you left off.

Settings

  • Nexus States — Comma-separated USPS state codes where you have nexus (e.g. CA,NY,TX). Tax is only charged for ship-to states in this list.
  • Tax shipping — Some states tax shipping charges. When ON, shipping is included in the taxable base where the state requires it. Default: off.
  • Rate Provider Default: Internal rate table.
  • Provider API Key — Required when using Avalara or TaxJar. Stored encrypted; after saving it shows as hidden.
