From 2005with the promulgation of Decree 90-2005, Law of the National Registry of Personsthe progressive incorporation of the Cui in the State dependencies.
This harmonization had to be completed in 2016but integration problems this was postponed.
The main laws that support this transition include:
- Decree 90-2005which establishes the incorporation of CU in state entities.
- Decree 25-71, Unified Tax Registry Lawwhich regulates the use of NIT.
