      "answer": "I cannot prepare a tax invoice without the ABN. Australian tax law requires that a valid tax invoice must include the supplier's ABN (or Australian Company Number if the supplier is not ABN-registered). Omitting the ABN means the document does not meet the legal definition of a tax invoice under the GST Act, and the recipient cannot claim input tax credits on it.\n\nThe owner should be advised that the ABN must be included on all tax invoices, regardless of space constraints."
