CiDATax Toolkit · Free Resources

The cross-border compliance toolkit your CFO actually uses.

Four interactive instruments that turn 27 EU member states, 50 US jurisdictions, five national PROs, and the 2026 regulatory calendar into answers you can act on before lunch. No email required. No paywall. No sales call.

Four instruments

The arithmetic of cross-border commerce, rendered usable.

We built these tools because the prospects who ended up signing engagement letters with us had typically spent six weeks before that call trying to answer the same questions in fragmented spreadsheets. The toolkit replaces those spreadsheets. Each tool is calibrated against 2026 thresholds and the live PPWR enforcement clock.

Why we give these away

Useful tools earn better clients.

The merchants and CFOs who reach the end of these tools without hitting a paywall are the prospects we want to talk to. They are self-directed, regulation-literate, and procurement-ready. That is a more efficient acquisition channel than gating utility.

It also keeps us honest. If our tools say you don't need fiscal representation, we shouldn't sell you fiscal representation. The toolkit prevents us from solving problems you don't have.

  • Calibrated against current EU directives, not last-year heuristics
  • Updated when the Court of Justice of the European Union publishes
  • Cross-checked with national PRO portals (CONAI, LUCID, CITEO, Ecoembes, Afvalfonds)
  • Reviewed by senior advisors before each release
  • Free in perpetuity. No upsell triggers. No email gating.

Found something you need help with?
