Collection of tax at source: e-commerce operators must collect notified tax, remit timely, and report supplies for reconciliation. Electronic commerce operators (not being agents) must collect an amount at a Government-notified rate not exceeding one per cent of the net value of taxable supplies where consideration is collected by the operator; remit collections within ten days after month-end; and file monthly and annual electronic statements of outward supplies, returns and amounts collected. Suppliers may claim credit for collected amounts; operator statements are matched with supplier returns, and unresolved discrepancies that show higher operator-declared supplies may be added to the supplier's output tax liability with interest. Authorities may require additional supply or stock information and noncompliance attracts penalties.
