How this calculator works
Estimate Irish Corporation Tax on trading profit and non-trading income. Inputs are validated and passed to the versioned Ireland engine whenever a field changes.
Formula
Trading profit is charged at 12.5%; supported non-trading income is charged at 25%.
Worked example
The result does not treat the Pillar Two minimum tax as a replacement domestic rate.
Scope and edge cases
The result card states its assumptions and status. Advanced reliefs, classifications or payroll facts outside the supported subset are never silently treated as zero.
