New business owners quickly realise the ATO loves acronyms. But behind the complexity is a logical system. Let’s break it down:
Understanding the Jargon:
• BAS – Report for GST, PAYG withholding, PAYG instalments
• IAS – Used when you’re not registered for GST but have PAYG instalments
• PAYG – Tax paid in advance toward your expected tax bill
What You Should Know:
• Missing due dates = penalties + interest
• ATO systems auto-calculate if you don’t lodge on time
• A tax agent can help align reporting with cash flow
Godspeed Accountants handles these for clients so you can focus on business—not paperwork.
