Streamlining Unique Identifiers For Taxpayers In Senegal

This project supports the Senegalese tax administration (DGID) in strengthening taxpayer identification and integrating unique identifiers across administrative systems. Although Senegal has a national ID system, incomplete data, such as missing tax IDs and contact information, limit effective tax collection and digital governance. In collaboration with DGID’s Datalab, researchers are tracking efforts to link tax identifiers with national ID numbers, particularly through recent property tax census activities. The study assesses data quality, harmonizes formats, and applies text-matching and geolocation tools to improve accuracy. It also supports coordination with the national statistics agency (ANSD) and builds DGID’s internal capacity for data-driven tax management and future evaluations on compliance and equity.
