Australia tax law

Stacy Casamedis is a registered tax agent. She has three branch offices and teaches undergraduates as a part-time lecturer at the local university. She has recruited 9 of her best students from her tax classes to interview clients and prepare returns. She is always available on the telephone if her employees wish to ask her a technical question. When she is busy Stacy lets these students use her ATO portal (a special ATO access system provided by the ATO to registered tax agents) and if necessary, use her electronic signature to lodge returns if things are very busy The Tax Practitioners Board (TPB) has received some complaints from Stacy's clients whose returns have been adjusted by the ATO and received penalties for false or misleading statements, and/or late lodgement. The TPB sent Stacy a letter asking her to set out her supervision and practice management systems. Stacy is too busy to respond because her mother is in hospital. The ATO informs the TPB that Stacy has not lodged her last 3 BAS quarterly statements for her practice. Required: Stacy has come to you for advice on whether if she has done anything wrong and if she will retain registration as a tax agent. Your answer must be supported by the Tax Agents Services Act 2009 and/or Tax Agents Services Regulations 2009 and other relevant TPB policy or rulings.
