On 24 August 2026, SUNAT released a comprehensive user guide titled “Revisa tu buzón SOL” (Check your SOL Inbox) to assist taxpayers in navigating the electronic notification system known as Buzón SOL. This digital mailbox is the official channel through which SUNAT delivers tax assessments, resolutions, requirements, and other legally binding communications to registered taxpayers. The guide provides step-by-step instructions for accessing the inbox using the taxpayer’s SOL credentials, interpreting notification statuses, and downloading attached documents. It also explains the legal implications of electronic notifications, which are deemed served upon availability in the inbox regardless of whether the taxpayer opens them. This initiative aligns with SUNAT’s digital transformation strategy under Legislative Decree No. 1448, which mandates the use of electronic means for tax administration acts. The guide is available as a downloadable PDF and aims to reduce taxpayer uncertainty, prevent missed deadlines, and improve compliance with tax obligations.
Key Takeaways
- Mandatory Electronic Notification Channel: The Buzón SOL is the sole official channel for SUNAT’s electronic notifications. Taxpayers are legally required to monitor it regularly, as notifications are considered served once made available in the inbox, even if unread. Failure to act on notifications can lead to enforcement actions, including coercive collection.
- Step-by-Step Access Instructions: The guide details how to log in with SOL credentials, navigate the inbox interface, filter notifications by type and date, and download PDF attachments. It also covers troubleshooting common access issues, such as forgotten passwords or locked accounts, directing users to the SOL recovery module.
- Legal Validity and Compliance Implications: Electronic notifications via Buzón SOL have full legal validity under Peruvian tax law. The guide emphasizes that taxpayers must configure alert settings and designate responsible personnel to review the inbox frequently. This ensures timely responses to information requirements, audit notifications, and payment demands, thereby avoiding penalties and interest accruals.
