Advance tax installment for 44AD

For individuals opting for presumptive taxation under Section 44AD, the entire advance tax is due by 15th March of the preceding financial year. If you also have salary income, this deadline applies specifically to your business income under 44AD. Your advance tax on salary income, however, follows the standard quarterly installment schedule. Failing to meet the 15th March deadline for 44AD income can result in interest charges under Section 234C.
