[Accounting error. Parameters restricted for Accounting in the United States]

  {
    '$severity': 'error',
    '$dataCode': 'InvalidRequest',
    '$message': 'The request contained parameters that are restricted for Accounting in United States [tax_analysis]',
    '$source': ''
  }

When trying to perform a PUT request to /sales_quotes/<ID>, I get the above response. I signed up in the United States, the Business Settings on the account list a U.S. State. Why am I getting a restriction error? How do I tell the API, I am in the United States?

If I remove the tax_analysis array from the body, it produces a 500 error.
