One foundation. Every report.
Onboard a client once. From a single normalized foundation, L3i generates every SALT report across the U.S. and Canada — and keeps the whole engagement tracked and audit-ready, continuously.
AI-assisted — each client in fast.
Transactions, documents, and more.
AI cleans and structures the data.
Any report, from the same foundation.
Ask the data questions; surface risk.
Deadlines and status across the book.
↻ Steps repeat continuously
AI-native by construction.
So the answer fits this taxpayer, in this state — and gets sharper every time. Deterministic where the rules are settled, AI where retrieval and judgment help.
Deterministic rules
For the rules that are settled, a deterministic engine makes the call — reproducible, not a guess.
Retrieval by meaning
Vector search and RAG surface the comparable call your team already made — by meaning, not keywords.
AI drafting
An on-prem LLM drafts and explains each determination in plain language.
Feedback loop
Every expert accept, reject, and correction feeds back — so the next answer starts from everything your firm has decided.
When the evidence is thin, L3i flags the gap and routes the call to a human expert instead of returning a confident wrong answer — and every determination it makes is cited to the controlling authority.
Messy data in. Answers out.
Bring client data in any format — L3i does the normalizing, not your team.
Data normalization
Messy client exports become a clean foundation every report can use.
AI-assisted cleanup
AI maps and normalizes fields automatically — your team reviews, not retypes.
Query your data
Plain-language questions across one client or your whole book.
Insights & risk
Approaching nexus, exposure, and filing risk surfaced before deadlines do.
Every SALT report. Hundreds of hours back.
Not a stack of isolated projects. Every report draws from that one shared foundation — so each builds on the last, and they all stay current as the data changes.
Nexus Studies
Where every client has triggered economic or physical nexus — automatically, and kept current.
Product Taxability
Taxability resolved across 2,000+ product codes and 50+ jurisdictions, as rules change.
Exposure Analysis
Prior-period liability quantified across jurisdictions — before it becomes a problem.
VDA Management
Disclosure workpapers generated and the process managed; your team submits to the state.
SUT Audit Reports
Documentation already assembled when an audit lands — not reconstructed under pressure.
Tax Returns
Clean, client-ready return summaries from the same foundation — not reassembled by hand.
A few of the highlights — from the same foundation, your team can generate any SALT report a client needs.
No patchwork of tools. Every report feeds the next.
Nexus flows into exposure, exposure into VDAs, normalized data into returns and audits — so audit readiness is the natural outcome, not a separate project.
