Hai Sir/Madam,
Please clarify my doubts in GST.
1.What is the treatment for input credit availed when transitioning from normal scheme to Composition Scheme in GST?
2.What about the entire Statement below mean?
(Registered foreign taxpayer shall pay the tax, interest, penalty, fees etc. within twenty days after the end of a tax period or within seven days after the last day of the validity period of registration, whichever is earlier).
