Reasons could be:
1. Incorrect industry code reported.
2. Incorrect % of the supply (SR, ZRL, ZRE, ES) reported in GST-03
    compared with GST-01. For example, SR 100% & ZRL 0% in your
    registraion info BUT ZRL 100% in GST-03.
3. Annual Turnover value, example 5,000,000 is monthly submission.
    and many other reasons.
