Collection of tax at source: e commerce operators must collect, remit, and report tax on platform supplies with matching and penalty consequences. Electronic commerce operators (not agents) must collect tax at source on the net value of taxable supplies made through them where they collect consideration, remit such amounts within ten days after the month of collection, and furnish prescribed monthly and annual electronic statements of outward supplies, returns and amounts collected. Suppliers may claim credit of amounts collected as reflected in operator statements. Details submitted by operators will be matched with supplier returns; discrepancies can be communicated and unrectified excess operator-reported values may be added to the supplier's output tax liability with interest. Authorities may require operators to furnish supply or stock details and non-compliance attracts penalty.
