Vaud legal source types covered
Current Vaud coverage is focused on cantonal tax-administration materials: tax scales, official forms, and administrative directives from the Direction générale de la fiscalité. General cantonal legislation and case law are not yet in the corpus; see the roadmap below.
Tax Scales & Tariffs (Barèmes)
Withholding-tax (impôt à la source) scales, cantonal income-tax scales, and federal direct-tax (IFD) scales, taken directly from the Direction générale de la fiscalité and published on vd.ch.
Tax Forms & Instructions (Formulaires)
Official tax declaration forms and general instructions — including annexes for securities (état des titres), professional expenses, and deferral-of-taxation forms — each tied to its source PDF, year by year where available.
Directives & Administrative Guidance
Administrative directives and guidance from the cantonal tax administration, such as filing-deadline directives for legal persons and organiser guides for events, from official Vaud sources.
Beyond Tax (Coverage Roadmap)
General Vaud legislation (Recueil systématique de la législation vaudoise / BLV), Grand Conseil parliamentary materials, and Tribunal cantonal case law are not yet in the corpus. Team and Enterprise customers can request these sources for prioritization.

Why Lawstronaut for Vaud legal research
Vaud tax information is spread across the cantonal tax administration's portal as individual PDFs — scales, forms, annexes, and directives that are reissued and renumbered from year to year. For humans, that means slow research. For AI systems, it's a bigger problem: fragmented source access, inconsistent formats, missing provenance, and weak citation trails.
Lawstronaut turns those sources into one structured legal data layer — source links, metadata, full text, versioning, and API/MCP access. Your product or agent retrieves the official Vaud document directly instead of relying on generic web search or unverified model memory. Every answer carries a citation, a timestamp, and a link to the official document — the provenance that makes a legal research platform defensible to auditors and regulators.
About Vaud legal coverage
Vaud is a French-speaking canton of Switzerland and a civil-law jurisdiction. Cantonal legislation is normally consolidated in the Recueil systématique de la législation vaudoise (BLV), laws are passed by the Grand Conseil, and cantonal case law comes from the Tribunal cantonal vaudois. Lawstronaut's current Vaud coverage is narrower and focused: it comprises the tax materials published by the Direction générale de la fiscalité (Administration cantonale des impôts) on vd.ch — withholding-tax and income-tax scales, official declaration forms, and administrative directives, in French.
Vaud tax materials change on an annual cadence: scales (barèmes), forms, and instructions are reissued each tax year, often under the same document family but with a new year suffix. Point-in-time data straight from the source is what keeps a Vaud tax answer correct today — letting you cite the exact scale or form that applied in a given year rather than the latest edition.
