Trust taxation rules updated: diversion thresholds and expanded related-person definitions affect tax-exempt status under Income-tax amendments. Amendments revise the charitable trust exemption framework by linking another exemption provision to the existing reference, treating diversion of income or property to disqualified persons as a ground for denial of exemption subject to a small-value exception, inserting an Explanation limiting retrospective effect for specified earlier periods, and expanding definitional scope by treating 'trust' to include other legal obligations and by defining 'relative' through an enumerated list while expressly including trustees and managers among disqualified persons.
