UK Statutory Residence Test - 22 strategies: NL 30% ruling, PT IFICI, ES Beckham - rules in code Honest: UK test 8/17, Spanish foral partial, Dutch Box 3 outdated.

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Spanish foral regimes are partial, Box 3 is outdated.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 —
