This assignment analyzes whether Big Bank Ltd is eligible to claim input tax credit for advertising expenses incurred according to GSTR 2006/13. It examines the relevant Australian taxation laws, specifically focusing on sections like 11-15, 15-10, and 15-25, to determine if Big Bank Ltd's acquisition meets the criteria for creditable use. The analysis considers the economic acquisition threshold boundary as defined in GSTR 2006/3 and concludes whether the issued invoice allows for input tax credit on GST supplies made.
