BAS Lodgement Dates

BAS Lodgement dates for BAS Agents.

These dates are established annually by the ATO as part of their BAS Agent Lodgement Program.
Broadly speaking:

There are no extra concessions for monthly activity statements, with the exception of the December activity statement which is due by 21 February rather than 21 January;

There is a 4 week concession for quarterly activity statements, with the exception of the December activity statement as its due date is already four weeks later for everyone.

Quarter Due date
1-July, August amd September 25th November
2-October, November and December 28th February
3-January, February and March 26th May
4-April, May and June 25th August

For BAS Agents to be eligible for these concessions, lodgement must take place via either the BAS Agent Portal, Standard Business Reporting (SBR) or Electronic Commerce Interface (ECI).
