Key Dates: November 2026
Staying on top of your deadlines keeps your business running smoothly and helps you avoid penalties. Here are the key dates business owners need on their calendar for November 2026, including BAS due dates and tax payment deadlines.
21 November
Lodge and pay your October 2026 monthly activity statement. (ATO)
If you report GST monthly, this is your deadline for the October period. As November 21 falls on a Saturday this year, please confirm with your agent whether Monday, November 23 applies to you.
25 November
Lodge and pay your Quarter 1 (July to September) 2026-27 activity statement if you lodge electronically. (Refer to the ATO’s registered agent lodgment program for the exact due date in November 2026.)
If you use a registered agent, please confirm your specific due date with them.
If either of these dates applies to you and you are unsure of your current status, please check now. Do not wait until the week your statement is due. Optima Partners‘ Business Advisory team helps Australian business owners stay ahead of these dates, ensuring nothing is a last-minute scramble.
