Tax is high-risk and circumstance-dependent. Each rule-sensitive calculator shows its jurisdiction, year, methodology and excluded cases.
Accuracy boundary
Rates and thresholds live in reviewed versioned rule modules, not scattered UI literals. Outputs remain educational estimates.
Current dedicated tax engines are UK 2026/27 and clearly scoped; they are not labeled global.
