The DIAN has released a new proposed resolution clarifying the timing surrounding the implementation of version 1.8 of the Technical Annex of the Electronic Invoice under UBL 2.1.
The implementation deadline will begin on April 2020 for large taxpayers and extend to October 2020 for all others. This new resolution will also consolidate in a single source all the current rules that regulate the electronic invoice in Colombia, provide clarification regarding the recent judicial challenges of the e-Invoicing mandate and specify the correct version of the technical documentation to be used by taxpayers.
