Check Tax
check_taxCheck inputs to calculate a tax return for a given jurisdiction. The 'input' argument must conform to the JSON schema returned by the tax_namespace_schema tool. Returns 'Success' on success, or validation errors if the input is invalid. If some inputs trigger a PARTIAL DISQUALIFICATION, the check still succeeds but includes disqualification details — proceed to calculate_tax to get the document and estimate the impact. Use this tool to validate inputs before calculating the tax return.
