How to Get Advance Tax Computation in India
Advance Tax is a critical compliance requirement for Indian taxpayers whose estimated total income exceeds ₹1 lakh in the financial year. Failure to pay advance tax attracts penalties under Section 234B and 234C of the Income-tax Act, which can significantly impact your cash flow and creditworthiness. This guide outlines the precise steps required to compute liabilities accurately using Form No. 3CDG or professional assistance.
Before you start
- Access to PAN card details for all business entities
- Updated financial statements (Balance Sheet, P&L) as of March 31, 2026
- Estimated income projection report including capital gains and dividends
Step-by-step
Estimate Total Income & Liability
Calculate your estimated total taxable income for the financial year ending March 31, 2026. Determine if you are liable to pay advance tax by checking if this amount exceeds ₹1 lakh after deducting TDS and other deductions.
Compute Instalment-wise Liability
Divide your total estimated tax liability into four instalments due on June 15, September 15, December 15, and March 15. Ensure the cumulative payment meets at least 15%, 45%, 70%, and 100% of the final liability respectively.
Prepare Form No. 3CDG
If you are a company or partnership firm, prepare Form No. 3CDG to declare your advance tax payment details before filing ITR-V. This form is crucial for maintaining accurate records with the Income Tax Department.
Generate Challan ITNS 281/CHALAN
Visit authorized banks or use NSDL/TIN portals to generate challans using Form No. CHALAN (ITNS-281). Ensure you select the correct head of account for each instalment corresponding to your due dates.
Make Payments via Online/Offline
Deposit the computed amounts into bank accounts designated by NSDL or other authorized banks. Retain all payment receipts and challan copies as they serve as proof of compliance during assessments.
File ITR with Advance Tax Details
Submit your Income Tax Return (ITR) via the e-filing portal before July 31, 2026. Upload Form No. 3CDG if applicable and ensure all advance tax payments are reflected in Schedule H of the return.
Verify Compliance & Obtain Acknowledgement
Check your ITR status on the Income Tax portal to confirm acceptance. Keep digital copies of Form 3CDG, challans, and acknowledgement receipts safe for future audits or scrutiny by tax authorities.
Common mistakes to avoid
- Missing the June 15 deadline which triggers a penalty under Section 234C even if total liability is eventually paid.
- Failing to update Form No. 3CDG for companies, leading to discrepancies during assessment proceedings.
- Overlooking TDS credits while computing advance tax, resulting in overpayment and unnecessary cash flow strain.
