If your organization has more than 50 tax authorities, you must first complete the bulk tax authority mapping process before proceeding with Sales Tax Automation setup. Here’s how:

*   Go to **Settings**.
*   Select **Taxes** under _Taxes & Compliance_.
*   Click **Set Up Sales Tax Automation**.
*   In the _Map Tax Authorities_ setup pop-up, click **Export File** to export all the tax authorities in your organization as an XLSX file.
*   Map each existing tax authority to a system-recognized tax authority in the exported file.
*   Click **Choose File** to upload the mapped tax authorities XLSX file, or drag and drop it.
*   Click **Import**.

Once the tax authorities are mapped, you can proceed with the [Sales Tax Automation setup](/us/inventory/help/settings/sales-tax-automation.html#set-up-sales-tax-automation).
