What is eu-tax-accounting?

A reference guide to business taxes, VAT, payroll and filing requirements in all 27 European Union countries. VAT is a consumption tax, while OSS and IOSS are EU systems for reporting certain cross-border sales; the guide is for orientation, not filing advice.

It is for planning where a company may register, reviewing VAT and payroll obligations, comparing tax rules, and building compliance checklists.

It helps compare country requirements and spot registration, deadline, invoicing and cross-border compliance questions before checking official sources or asking a tax adviser.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00089	$0.01026
Opus 5.5	$0.00036	$0.00410
Sonnet 5.5	$0.00018	$0.00205

Security

Grade A, and why

eu-tax-accounting scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.

EU Tax & Accounting — 27 Member States

Orientation reference for corporate tax, VAT, payroll taxes, filing deadlines, cross-border rules, e-invoicing and compliance requirements across the European Union.

Not tax advice. Use this as a checklist/orientation layer only. Every rate, threshold and deadline below changes annually and varies by region, fiscal year, sector and entity type. Verify each figure against the official tax authority (linked per section) or a licensed local adviser before filing, registering for VAT, processing payroll, optimizing, or restructuring. Specific values are tagged with a last-verified date; where a 2026 number was not confidently confirmable, the entry points you at the official source instead of asserting a figure.

Verified baseline: figures reflect rules as of June 2026 unless a cell carries its own note. The fastest cross-country starting points: Tax Foundation EU tables (CIT/VAT/payroll, updated annually), PwC Worldwide Tax Summaries (per-country, authoritative detail), and the EU VAT rates database.

2026 e-invoicing snapshot (full table in §6): Germany B2B receive mandatory since Jan 2025, issue phased 2027-2028; Belgium B2B mandatory since Jan 2026; Poland KSeF live from Feb 2026 (large) / Apr 2026 (all VAT-registered), penalties from Jan 2027; France B2B receive Sep 2026, issue Sep 2026-2027 by size; Spain (Crea y Crece) royal decree adopted Mar 2026, phase-in ~2027-2028. VAT in the Digital Age (ViDA) rolls out platform-economy and digital-reporting rules from Jul 2028 (platforms, single registration) to Jul 2030 (intra-EU digital reporting), full alignment by 2035.

Safety gate

Before executing commands or changing external systems, confirm scope, credentials, target environment, rollback, and required approval. Pin and verify third-party artifacts; never expose secrets to client code or logs.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
