In detailed guidelines, the CBDT said TCS will be collected on the gross amount charged to the customer. In case the buyer receives a discount, the TCS will be on the final invoice raised to the buyer irrespective of whether the first e-commerce operator is offering the discount or the second. The CBDT also said in case of purchase of goods which are not under the purview of Goods and Services Tax, the TDS will be applicable on the amount without including state levies, VAT or other tax.
