As per government policy of government of India there is no tax on export in India
Like if we purchase any taxable Goods from same state for sales in for sales in India than we have to pay VAT tax in India.
Like if we purchase any taxable goods from interstate for sales in India than we have to pay CST tax in in india and many more
But like if we purchase any taxable goods from India and we purchased that goods for sales out of India or like purchased that goods for exports sales than we have not liable to pay any tax like VAT tax CST tax and many more
So in exports if Purchase any taxable goods from India for export than buyer have to purchased that taxable goods against “H Form” as per government policy of government of India, if we purchased goods Against “H FORM” for Export we have to take “H Form” from our VAT department and give it that “H Form” to the seller of goods with copy of Bill of landing, for as proof of whatever we purchased from them that goods are exported this “H Form“ and Bill of landing is the proof of exported goods
