My W1 amount on my IAS differs to my payroll report in MYOB. I just altered the figure last month but it has happended again so there must be an underlying problem. In a previous post, it was suggested to log into your BAS and click on Settings to see what is being captured in the W1 field but I can't find the Settings. When you say log into your BAS, do you mean Prepare BAS/IAS? I'm not sure I am looking in the right place. Any help would be appreciated. Thanks.
