A GST dealer who does government work contracts supplies services as well as material with multiple tax rates. In such cases, adding the SAC code to the tax invoice and adding 18% tax rate is enough? Or add HSN code material-wise and charge tax rate separately for material and service?
In such cases, it is doubtful whether it is sufficient to enter the code that comes with SAC code 99 in table number 12-HSN-wise summary of outward supplies in the monthly GSTR1 return or whether the material details should also be given by adding the HSN code.
Is there any legal exception to fill GSTR1- Table No.12-HSN-wise summary of outward supplies details due to transactions between GST regular dealer (Taxpayer) and GST Tax deductor (Government organization)?
