GST invoice

A tax invoice issued under India's Goods and Services Tax, carrying the seller's GSTIN, the tax rate and the tax amount shown separately. A business buyer needs one to claim input credit.

A receipt and a tax invoice are not the same document. A receipt records that money was paid; a GST invoice makes a tax claim, which is why it must carry a GSTIN and a gapless invoice number series.

Online courses sold to Indian buyers are generally taxable supplies, and a seller registered for GST is expected to issue proper invoices. A seller not registered should not be issuing documents that look like tax invoices.

For example

A course listed at ₹10,000 plus 18% GST bills ₹11,800: the invoice shows ₹10,000, ₹1,800 of tax, the academy's GSTIN and the HSN/SAC code, separately. A company buying training for staff reclaims that ₹1,800 as input credit — so for a business buyer, a proper invoice makes the course 18% cheaper than one without.

On Prolaud

An academy that enters its GSTIN issues GST tax invoices with a gapless number series per financial year; without one, the same purchase produces a plain receipt that does not claim to be a tax document.
