Advance Tax for Architects in India — Deadlines, Calculation & Rules
Last updated: March 2025 · Reviewed by TaxTap CA team
If your tax liability exceeds ₹10,000 for the year, advance tax is mandatory. Under 44ADA, pay 100% by March 15 in one shot. Otherwise, pay quarterly: 15% by Jun 15, 45% by Sep 15, 75% by Dec 15, 100% by Mar 15.
Who this applies to
- Architects with annual tax liability over ₹10,000
- Architects under 44ADA who want the simplest payment method
- Architects with irregular project-based income
- First-time freelancers unsure about advance tax obligations
How this works for Architects
Advance tax = pay-as-you-earn. The government wants its share before your annual filing.
Under 44ADA: pay 100% in one installment by March 15. Simplest option.
Not under 44ADA: pay quarterly — 15% (Jun 15), 45% (Sep 15), 75% (Dec 15), 100% (Mar 15).
Missing a deadline triggers interest under Section 234C — 1% per month on the shortfall.
Estimate annual income → calculate tax on deemed/actual profit → subtract TDS → pay balance as advance tax.
Pay via income tax portal using Challan 280. Keep receipt for ITR filing.

What should you do?

Not under 44ADA? Track income quarterly and adjust payments each quarter.
Tax liability under ₹10,000? No advance tax needed.
Set calendar reminders for all due dates — interest penalties add up.
Mistakes to avoid
Not paying advance tax at all — leads to interest under Sections 234B and 234C.
Overpaying and unnecessarily locking up cash flow.
Under 44ADA, paying quarterly instead of using the single March 15 payment.
Not adjusting estimates when a big project comes in mid-year.
Forgetting to subtract TDS credit before calculating advance tax amount.
