Section 44AD / 44ADA — one instalment
100% by 15 Mar 2027
If you declare presumptive business income under Section 44AD or presumptive professional income under Section 44ADA, the four dates above do not apply — the whole advance tax is due in a single instalment by 15 March, and Section 234C runs for one month on any shortfall. Section 44AE does not get this concession.
Advance tax calculations are based on estimated income and standard slab rates. Surcharge on income above ₹50L is included at standard rates (marginal relief on surcharge is simplified). Old-regime figures assume only the standard deduction — your actual liability is lower if you claim 80C/80D/HRA and other deductions. Consult a tax professional for exact advance tax computation. RushTax is a freelance consulting service — not a CA firm.
