About This Tool

sunat-cli is an open-source automation tool that interacts with SUNAT (Superintendencia Nacional de Aduanas y de Administracion Tributaria) web portals on behalf of authenticated users. It does not scrape, collect, or store third-party data.

User Responsibility

This tool automates form submissions using YOUR credentials (Clave SOL). You are solely responsible for:

The accuracy of tax declarations submitted through this tool
Compliance with SUNAT deadlines and tax obligations
Safeguarding your Clave SOL credentials
Reviewing all operations via --dry-run before execution

Legal Basis for Automation

Peruvian law does not prohibit automated interaction with government web portals when performed by the authenticated account holder for their own tax obligations.

Ley 27269 — Ley de Firmas y Certificados Digitales: Electronic submissions have the same legal validity as manual submissions.

Decreto Legislativo 1310 — Simplificacion administrativa: The State shall promote the use of technology to simplify administrative procedures.

Data Protection

sunat-cli operates entirely on your local machine. No data is sent to third-party servers. API calls go exclusively to official SUNAT endpoints (*.sunat.gob.pe).

Credentials stored locally in ~/.sunat/ (encrypted)
Audit logs stored locally in JSONL format
OAuth2 tokens cached locally with 1-hour TTL
No analytics, telemetry, or external data transmission

Ley 29733 — Ley de Proteccion de Datos Personales: All personal data processing occurs locally under the user's control.

SUNAT Terms of Service

SUNAT's Operaciones en Linea portal does not explicitly prohibit automated access by authenticated users. However:

This tool uses headed Chrome (not headless) to comply with SUNAT's bot detection
Operations include realistic delays between form submissions
No rate-limiting circumvention is attempted
The tool respects session timeouts and re-authenticates properly

Disclaimer

sunat-cli is provided "as is" without warranty. The authors are not responsible for any tax penalties, incorrect declarations, or financial losses resulting from the use of this tool. Always verify declarations with a qualified tax professional (contador).

This tool is not affiliated with, endorsed by, or officially connected to SUNAT in any way. SUNAT is a trademark of the Peruvian government.
