LIFF Tax Inbox

LIFF Tax Inbox is the tax-communications layer for organizations operating at scale in Brazil. It monitors electronic tax mailboxes, tax clearance certificates and tax current accounts across federal, state and municipal environments, and consolidates everything into a single inbox where each occurrence becomes a tracked action with an owner, a deadline and a complete audit trail.

The silent-deadline problem. In Brazil, several tax communications produce legal notice by the mere lapse of the statutory period, even when the taxpayer never actively opens the message. Organizations operating dozens of legal entities, state registrations and municipal registrations across the federal e-CAC/RFB environment, state DEC/DTEC/SEFAZ systems and municipal electronic domiciles face a structural visibility gap. The risk is not reading a communication badly, it is not reading it at all. LIFF Tax Inbox closes that gap with automated, recurring collection across every enabled environment, respecting the notice rules applicable to each one.

Three monitored surfaces. Tax mailboxes: automatic multi-source, multi-entity, multi-registration collection of notices, summons, tax communications, installment programs, offset proceedings and collection channels at federal, state and municipal level. Tax clearance certificates: issuance, PDF archiving, validity control, renewal scheduling and preventive alerts for the certificates available electronically. Tax current accounts: recurring reading of the environments made available by tax authorities to identify debts, divergences, registration inconsistencies and pending items that could block or compromise certificate issuance, surfaced before they become an obstacle.

From collection to accountability. The platform runs a continuous five-stage flow. Collection: automated monitoring of the registered mailboxes and domiciles. Ingestion: messages extracted and normalized into a single structure, independent of source or government level. AI triage: classification by document type, risk, urgency, related legal entity or registration, and subject matter. Deadlines and alerts: identification of statutory due dates, countdown and expiry warnings. Action: every occurrence becomes a task with an assigned owner, status and full traceability. The service is delivered as a managed service, with LIFF continuously operating the monitoring, triage and task-governance processes so nothing depends on someone remembering to check a portal.

AI that organizes, humans that decide. LIFF Tax Inbox does not perform legal or accounting analysis and does not resolve occurrences on the taxpayer's behalf. It guarantees that nothing arrives unnoticed, that every deadline is visible, that every document is preserved as evidence, and that every action is attributable, expanding the capacity of tax, legal and controllership teams instead of replacing their judgment. Every classification is traceable to the original document retrieved from the government environment.

Scope boundaries by design. Monitoring covers electronic tax environments that are electronically available and technically accessible to the platform, defined and validated during implementation. Communications delivered physically or outside the monitored electronic systems, judicial proceedings, official gazette publications and judicial deadline control are outside the scope of this offer.

Delivered on AWS. This service is built to take advantage of AWS capabilities in support of customer tax communication needs. The solution can run on AWS or involve AWS infrastructure, depending on the specific requirements of each customer, including hosting for the Tax Inbox platform components, data processing for tax communication and document collection, AI-assisted analysis for classification and triage of tax notices, security capabilities that protect access credentials and digital certificates, and storage for captured documents, issued certificates and audit evidence, supporting data residency in Brazil and LGPD compliance.
