IC Index formula
IC = Corp Tax % − Income Tax % − Payroll Tax %
A rising IC Index signals that governments are shifting their fiscal base away from taxing people toward taxing productive capital. When Norway, Saudi Arabia, or the DRC begin to look like comparators — rather than outliers — the thesis is materialising.
IC > 0 — capital dominant
IC −10 to 0 — transitional
IC < −10 — labour dominant
