They have most recent MYOB payslip with all relevant details, incl Super
How quickly are they getting tax in
I'm usually waiting on banks etc
The ATO will not care when they get their return in.
In business you cannot tell the ATO my bookkeeper is on vacation, please wait. They will say and for every day you don't comply here is a fine. If she dies or seriously ill then you can ask for month or so.
We once has BAS where we paid the tax but the ATO system lost the paperwork, even though sent by our accountant. Turns out that BAS event they lost a few as ours was not the only one form our Accountant to get a letter.
Did the ATO go "sorry mate, DOH"? No they wrote to us threatening fine (i think $1000) et all if we did not provide details again ASAP (like yesterday).
I would fix now.
