I have a sole proprietorship for web design. The expected revenue was supposed to be below 20L. Hence we had not opted for GST registration. But it has crossed above 20L to eg 27L in last financial year. I have not registered for GST till now. It seems now filing for ITR AY 2021-22 there will be GST penalty? I read it's 100%. Is that 18% of all 27L or only 18% of 7L ? Shuuld it be paid while filing or need to wait for notice? The ITR filing is on individual name and not proprietorship name. There is no company PAN. Thanks everyone in advance.
