Fundamentals of Tax 2025-2026: Goods and services tax (GST) package

This package introduces practitioners to the foundational rules of Australia’s Goods and Services Tax (GST) system, with a strong focus on applying those rules in practical compliance settings. Participants will learn how to determine GST liabilities, entitlements to input tax credits (ITCs), and how to calculate the net amount payable or refundable. The sessions also equip learners with the skills to accurately complete a Business Activity Statement (BAS), ensuring compliance through correct account coding and identification of taxable versus non-taxable transactions.

Across the 2 sessions, participants will be able to:
