Effective date of composition levy clarified: applicability for provisional registrants, existing registrants, and new registrant timing. Effective date of the composition levy depends on registration timing: provisional registrants who opt apply the appointed date; those opting after registration apply from the beginning of the financial year; applicants opting in a new-registration application take effect either from the date of becoming liable if application filed within thirty days, or from the date of grant of registration if filed later.
