What is the due date for payment of advance tax if the assessee has opted presumptive taxation scheme under Sections 44AD or 44ADA?

Presumptive taxation advance tax: full liability payable in a single instalment before the fiscal year start under presumptive provisions.

An assessee who opts for the presumptive taxation scheme may pay the entire advance tax liability in a single instalment on or before March 15 of the previous year, thereby meeting advance tax obligations in one payment instead of periodic instalments.
