Maker here. I built Taxmora because I kept moving between European countries (DE → NL → eight months in Lisbon → a UK contract) and every move added a tax authority to my life. Two accountants gave me three different answers. So I did what developers do: I coded the tax law. - 5 countries, 2025/2026, every rate cited to the statute - 22 strategies with eligibility rules in code - 977 tests — and the German calculator still shipped broken for the first 3 hours (decimal point, €12,096 became €1,209.60) The honest part is in the description: the UK test is 8/17, the Spanish foral regimes are partial, Box 3 is outdated. That's why it's €29 while it's in this state. Happy to answer anything about coding tax law, the 6-layer LLM guardrail for tax advice, or the full build story — [https://dev.to/achiesun/...](htt...
