Reduced corporate tax option for manufacturing domestic companies subject to eligibility, deduction exclusions and carry forward restrictions. A domestic manufacturing company registered on or after 1 March 2016 may elect a concessional tax regime under section 115BA by the prescribed due date. Eligibility requires exclusive engagement in manufacture/production (including related research and distribution), computation of total income after excluding specified deductions and certain Chapter VI-A allowances (except section 80JJAA), and non-set-off of losses attributable to those deductions. The option, once exercised, is irrevocable for the same or subsequent years except where an option under section 115BAA is exercised.
