Royal Inheritance Tax Exemption Shields Charles's Vast Estate Transfer

King Charles III's £30 million in tax payments since September 2022 masks a structural exemption: assets passing between monarchs escape inheritance tax entirely. Queen Elizabeth II's estate transferred to Charles tax-free, while ordinary estates above the threshold face 40% levy. This exemption, embedded in the 1993 voluntary taxation framework, remains politically significant—more so than the disclosed tax figure itself.
