The Central Board of Indirect Taxes and Customs (CBIC) has notified e-invoicing for businesses with turnover above Rs 500 crore, increasing the threshold for mandatory issuing of electronic invoices from the earlier limit of Rs 100 crore turnover, providing relief to small scale companies.Further, units in Special Economic Zones (SEZs) are not required to follow e-invoicing rules, the government has said in the notification dated July 29. E-invoicing for business to business transactions will be implemented from October 1, 2020.“We will not do it for (businesses with) Rs 100 crore sales but will start with Rs 500 crore and as it stabilises, we will do it for (businesses with) Rs 100 crore sales and more,” Yogendra Garg, principal commissioner, GST policy at the CBIC had said in a webinar last week. The notification issued also includes formats or schemas for execution of e-invoicing by trade.The government intends to implement e-invoicing or electronic submission of sales invoice to bring more transparency in sales reporting, automate data entry work, reduce errors and mismatches, capture sales related details in the system instantaneously and improve compliance. The practice followed in many international markets will also prevent tax evasion while reducing chances of audits or surveys.Insurance and banking companies, financial institutions, non-banking financial institutions, goods transportation agencies and passenger transportation services will be exempted from e-invoicing and dynamic QR codes.CBIC had also mandated implementation of dynamic quick response (QR) codes on e-invoices from October 1, however, this has not been made mandatory in the July 29 notification. A QR Code contains details of an invoice such as GST identification numbers of suppliers, receiver and invoice numbers, which can be checked instantaneously without internet access.
