Who has to lodge?
Only SMSFs registered for GST need to lodge a BAS. Registration is mandatory once your fund's GST turnover hits $75,000. Below that threshold, registration is optional.
When is it due?
- Q1 (Jul–Sep) — due 28 October
- Q2 (Oct–Dec) — due 28 February
- Q3 (Jan–Mar) — due 28 April
- Q4 (Apr–Jun) — due 28 July
What goes in it?
For most SMSFs: total sales, GST collected on those sales, capital and non-capital purchases, and GST paid on purchases. The net of GST collected vs paid is what you owe the ATO (or what they owe you).
How SMSF Simplify helps
Every transaction you enter is automatically tagged with a quarter, and GST is calculated on the fly using the 1/11th method. When the quarter ends, your BAS Summary is one click away — no spreadsheets, no manual totals, no panic.
