Prepare it without the ABN.", "answer": "I can't prepare it that way. For a sale of this size (well over the $82.50 GST-inclusive threshold), the ATO requires a valid tax invoice to show the seller's ABN - it's not an optional formatting choice. Leaving the ABN off means: (1) the document is not a legally valid tax invoice, (2) the client cannot claim an input tax credit for the GST on the purchase, and (3) if the client doesn't hold a valid ABN-bearing invoice, they may be obliged to withhold at the top marginal rate (47%) from the payment as a 'no ABN quoted' withholding, which would actually cost the business money and create a dispute with the client. I'm happy to prepare a tax invoice that saves space in other ways (e.g. a compact layout, summarised line items), but the ABN, the seller's identity, the words 'Tax Invoice', the date, a description of the supply, the GST-inclusive total and the GST amount (or a statement that GST is included) all need to stay on it to remain compliant. Let me know if you'd like me to issue the compliant version instead."}]}
