In a significant step toward digitizing tax administration, Bolivia’s National Tax Service (SIN) has officially implemented the new National Taxpayer Registry (RNC) as of May 2025, replacing the former Biometric Digital Registry (PBD). The upgraded system, part of the SIAT en Línea platform, represents a shift toward full online tax compliance and secure identity verification.
The new RNC not only prevents the alteration of taxpayer data but also enables cross-verification with major public institutions, such as:
- SEGIP (General Service of Personal Identification)
- SERECI (Civil Registry Service)
- SEPREC (Commercial Registry)
This interoperability ensures data accuracy, improves fraud prevention, and streamlines economic classification under Bolivia’s CAEB 2022 framework.
Why This Matters: From Biometrics to Blockchain Logic
The SIN’s move aligns with a broader Latin American trend: enhancing taxpayer transparency through digital identity systems. The RNC secures the Tax Identification Number (NIT) process with encrypted data sharing and an end-to-end online workflow — eliminating the need for in-person visits in most cases.
According to SIN officials, the system ensures:
- Verified classification by economic activity and sector
- Real-time validation of residential and commercial addresses
- Prevention of identity fraud and regulatory evasion
In Situ Inspection: New Deadlines and Rules
Despite digitalization, physical inspections (In Situ) remain required for certain economic activities, especially those subject to VAT or special regimes.
- Online registration: inspection within 5 business days
- In-person registration: inspection within 10 business days
- Remote locations: additional 5-day extension if outside SIN agency coverage areas
These inspections aim to verify the taxpayer’s physical location, declared activities, and supporting documents to ensure accurate registration and classification.
