⚠ SBIE payroll/asset rates and the 15% minimum rate are OECD-published transitional table values, pinned in this tool behind a constants_version field. Jurisdiction-level QDMTT enactment and rate are your own inputs — this tool never vendors a QDMTT-enactment table. Verify current rates against OECD Administrative Guidance before relying on this for a filing.
