Is GSTR required for F&O traders

Hi, Today IT Department released new ITR forms and it requires GSTR Code. Is GSTR code required for F&O traders?

No

That’s for businesses filing under presumptive tax scheme

If u need an audit then anyway u can’t file under that scheme

But if I file under presumptive taxation (as F&O trader) and GSTR No is made mandatory then what do I do?

This is the latest ITR 4 form. Schedule BP has new field E9 - GSTR No. Dont know if this is mandatory.
