Hi SamELinks
Thanks for clarifying. I've checked this with our specialist team and there is an issue with all payroll categories not appearing in the drop down box when there is a large number of payroll categories. Our developers are looking into this.
In the meantime, you could set up the manual BAS which will allow you to select all payroll categories. You can then copy the amount from the manual BAS into the online BAS form for lodgement. This will save you having to calculate the W1 amount yourself.
We do apologise for the inconvenience caused.
