As of January 2022, e-Invoicing became mandatory for natural persons and companies with incomes over 200,000.01 USD and under 300,000.00 during the last fiscal year. Taxpayers who want to issue and send an e-Invoice are required to register and get authorization from the tax authority (The Internal Revenue Service-SRI).
