Regarding Form-WW TNVAT act (profit issues)

Dear Experts.. 2016-2017 (April, May, June) Sales amount under VAT Act Rs. 2 crore. Form WW and Income Tax has been filed for this. 5% Gross profit is shown in this Form WW. The commercial tax officer said that this is wrong and has given notice that 15% gross profit should be shown and tax should be paid.
I humbly request you to answer this.
