Lexplorer Swiss Tax Research

Research Swiss tax law

Brand: Lexplorer

Category: Operations
Primary Subcategory: Legal Research Engines

Integration details

Description

Lexplorer searches Swiss tax law with verified, citable sources: federal tax acts (DBG, MWSTG, StHG, VStG, stamp duties), the tax acts of all 26 cantons, the official tax handbooks and administrative practice of 24 cantons, the federal administrative practice (ESTV and SSK circulars, VAT publications), plus commentary and academic doctrine. ChatGPT plans the research the way a tax professional would: statute first, then administrative practice and doctrine, and for cantonal questions the sources of the right canton — every key statement with a precise citation and a link to the original source. Examples: "What does § 31 of the Zurich tax act (StG ZH) say?" · "How are dividends in kind treated for withholding tax? Include ESTV practice." · "How does the DBG regulate employee participations?" · "Compare the practice in the cantons of ZH and ZG." Built for tax advisors, fiduciaries, lawyers and in-house teams. Requires a Lexplorer account (login on first use) — more at lexplorer.ch.

Tools

17 tools agents can invoke

Recursive hierarchical tree (kanton → categories → sources → documents). max_depth 0-3. Replaces 3-5 sequential nav_list_* calls.
nav_tree
Read the pre-generated navigation overview (_navigation.md) of a canton: categories + sources.
get_kanton_navigation_md
Find where a source/document lives in the hierarchy by name pattern. Returns canton + category + breadcrumb. Pass filter_kanton when you already know the canton — otherwise generic patterns may sort ZH out of the LIMIT 20 window.
nav_find
Read the full text of one indexed chunk plus links to its parent document (PDF and Markdown) in the Lexplorer corpus. Results include lexplorer_url (public source page) — when citing this source in an answer, use lexplorer_url as the clickable markdown link.
get_chunk_content
Read one research playbook (Markdown skill file) by name.
get_skill
Hybrid search (semantic + keyword, RRF-fused) over the indexed Lexplorer chunks. The query text is embedded via Google Vertex AI (EU region); results come exclusively from the Lexplorer corpus. Good when mixed. Results include lexplorer_url (public source page) — when citing this source in an answer, use lexplorer_url as the clickable markdown link.
search_chunks_hybrid
German full-text keyword search over the indexed Lexplorer chunks (database only, no external service). Best for exact terms (§, Art-Nr, named concepts). Results include lexplorer_url (public source page) — when citing this source in an answer, use lexplorer_url as the clickable markdown link.
search_chunks_keyword
List all 26 Swiss cantons + CH (federal) with chunk/source/doc counts from the Lexplorer tax-law index.
nav_list_kantons
List the source categories (legislation, administrative practice, doctrine, ...) indexed for one canton.
nav_list_categories
List the text chunks of a parent document.
nav_list_chunks
List the top-level documents of an indexed source. Results include lexplorer_url (public source page) — when citing this source in an answer, use lexplorer_url as the clickable markdown link.
nav_list_documents
List the research playbooks (Markdown skill files) shipped with the Lexplorer corpus.
list_skills
List the indexed sources of a canton (optionally filtered by category).
nav_list_sources
Read one Markdown file from the Lexplorer corpus file store by a relative path as returned by other tools (e.g. a chunk or text.md). Paths outside the corpus are rejected.
read_storage
Read the full text (text.md) of an indexed document from the Lexplorer corpus in pageable slices. First call returns slice 0 + slices_preview (TOC). Results include lexplorer_url (public source page) — when citing this source in an answer, use lexplorer_url as the clickable markdown link.
get_document_slice
Semantic vector search over the indexed Lexplorer tax-law chunks. The query text is embedded via Google Vertex AI (EU region, gemini-embedding-2); results come exclusively from the Lexplorer corpus. ALWAYS pass filter_kanton. Results include lexplorer_url (public source page) — when citing this source in an answer, use lexplorer_url as the clickable markdown link.
search_chunks_semantic
Read the maintenance notes (_UPDATE.md) of an indexed source: pipeline, update routine, quality notes. Read-only; despite the name it updates nothing.
get_source_update_md
