The Tax Practitioners Board (TPB) 2017/18 annual report highlights that only 95% of practitioners are compliant with all aspects of the law. For the 3,887 non-compliant practitioners, the TPB compliance process involves education, penalties, and enforcement of the law.
The actual sanctions imposed for the year show enforcement is rarely applied by the TPB. For 2017/18 there were only 24 terminations, 81 imposition of a written order, and 182 written cautions. Just like ASIC and APRA, it seems the TPB are very light-on in enforcing the law.
