31 October falls on a Saturday this year, and that changes one tax deadline but not the other.
Lodging your own return? The ATO says that if 31 October falls on a weekend, the due date is the next business day. For 2026, that's Monday 2 November.
Using a registered tax agent? The ATO says you need to engage them before 31 October. Agents can generally lodge for clients later than that, but 31 October is also the final date for an agent to add new clients for this year's program. So don't leave the phone call to Monday.
One more thing: if you had prior-year returns outstanding at 30 June 2026, those all need to be lodged by 31 October to keep access to the agent's later dates.
If you're in Williams Landing, Point Cook, Tarneit, Werribee or Hoppers Crossing and still need someone to look after this year's return, call us this week.
