Don’t Miss a Date: The Complete 2026-27 Tax Filing Roadmap
Dated 25.03.026 : With the new tax laws kicking in on April 1, 2026, your filing cycle is getting a digital makeover. Under the new system, “Previous Year” and “Assessment Year” are merged into a single Tax Year. Here are the critical dates you and your employees need to track:
Q1: April – June 2026 (The Setup Phase)
- April 1: New Income-tax Act, 2025 and Form 124 (HRA/Investments) go live.
- May 31: Deadline for employers to issue Form 130 (Old Form 16) for the 2025-26 period.
- June 15: First installment of Advance Tax (15%) for the new tax year.
Q2: July – September 2026 (The Filing Season)
- July 31: Final deadline to file Income Tax Returns (ITR) for the financial year ending March 2026 (under the old 1961 Act rules).
- September 15: Second installment of Advance Tax (45% cumulative).

Q3: October – December 2026 (The Mid-Year Correction)
- October 31: Audit Deadline. If your business (or your readers’ businesses) is subject to a Tax Audit, this is the final date to file the return for the previous tax year.
- December 15: Third Advance Tax Installment. You must have paid 75% of your total estimated tax for the current year by this date. This is a crucial “check-in” for freelancers and business owners.
- December 31: Revised/Belated Return Deadline. The last chance to file or correct your return for the 2025-26 period (the “old act” transition year).
Q4: January – March 2027 (The Final Sprint)
- January 15: Deadline for employers to deposit TDS for the December quarter.
- March 15: Final Advance Tax Installment. 100% of your tax liability for the 2026-27 tax year must be paid by today to avoid interest penalties.
- March 31: Investment Deadline. The final day to make tax-saving investments (under the sections that replaced 80C/80D) to reduce your tax bill for the current year.
