Today, we have received numerous emails regarding Belcofin's compatibility with the new Belcotax requirements.
Starting from income year 2026, it will no longer be possible to submit files in XML format. Instead, you will be required to use the JSON Lines (JSONL) format.
As a user, there is no need to worry.
We will ensure that Belcofin is fully compatible with the new requirements by February 2027, allowing you to submit your files without any issues.
