We have executed LUT in GST and exporting services without payment of tax. We are facing lots of challenge in getting the Input refund from GST department due to various impractical grounds.Want to know your opinion can we export the services with payment of tax by utilising input tax credit as this seems to be less complicated model. Will there be any legal challenge in exporting the services with payment of GST even though LUT is present. We will be doing this for three months and for future months we will be exporting without payment of tax.
