The government of Panama has enacted Decree 115/2020 by which it mandates that all taxpayers excluded from the obligation of using electronic fiscal machines attached to their POS systems will be required to issue pre-validated electronic invoices. The decree also establishes that this mandate will be effective on August 1, 2020 but the tax administration may establish specific compliance schedules for certain groups of taxpayers. The electronic invoicing system adopted by Panama is similar to that of Mexico, as it requires invoices to be validated by an authorized entity acting on behalf of the tax authority (PACs). In 2019 Panama started an e-Invoicing pilot program with the largest taxpayers of the country. The Ministry of Finance is expected to issue further regulations soon about this mandate.
