Transitional rule — which form applies?

⚠️ Which form applies depends on the tax year the compliance relates to, not the calendar date you file. Proceedings for tax years beginning before 1 April 2026 (assessments, appeals, TDS for transactions up to 31 March 2026, and Section 89 relief for those years) continue on the old forms.
