Hi Mapleloor
Thanks for your post. If you are lodging the BAS online, the Activity Statements window shows the Standard due date. When you click on the statement you want to lodge, the details, including the due date and required fields, are retrieved from the ATO. If this is showing a different date and fields than expected you would need to contact the ATO.
If you are referring to the PAYG Instalment (T fields) amounts not being prefilled, these values need to be manually entered when completing your statement.
Please let me know if you need further help.
