# Compliance Check > Verified compliance deadlines and rule changes for small businesses in the UK and > Europe. Every entry is verified against an official government/EU source, carries > that source URL, a verification date, and an honesty status (confirmed / announced / > proposed / unverified). The record is append-only: corrections are published openly, > never silently edited. Source freshness (including failures) is public. This site is designed to be consumed by AI tools and agents. The complete dataset is one static JSON file — no key, no auth, CDN-served with permissive CORS, rebuilt after every verified update. Stable entry ids; corrections reference the id they supersede via a "supersedes" field. Coverage: United Kingdom (51), European Union (10), France (9), Romania (8), Germany (7), Poland (7), Belgium (5). Domains: tax filing, e-invoicing, VAT, company-register duties, employer duties, landlord rules, EU AI Act. Checked daily.
