March 31, 2026 Deadlines: MCA Director KYC Overhaul and TDS/TCS Correction Final Window
Two Major Deadlines You Cannot Afford to Miss
March 31, 2026 is not just the end of the financial year. It marks the effective date of a landmark change to Director KYC rules under the Companies Act, and the final window for correcting old TDS/TCS statements before the Income Tax Act, 1961 is formally repealed. If you are a company director, a CA handling corporate clients, or a business owner who deducts TDS, this article covers the two most critical compliance actions you must complete before March 31.
Part A: MCA Director KYC Overhaul – Annual Filing Replaced by Triennial Filing
What Changed?
The Ministry of Corporate Affairs (MCA) has notified the Companies (Appointment and Qualification of Directors) Amendment Rules, 2025 vide Notification No. G.S.R. 943(E) dated December 31, 2025, effective from March 31, 2026. The key change: annual Director KYC filing is now replaced with a triennial (once every three years) filing requirement.
Under the substituted Rule 12A of the Companies (Appointment and Qualification of Directors) Rules, 2014, every individual holding a Director Identification Number (DIN) as on March 31 of a financial year must now file KYC details in Form DIR-3-KYC-Web on or before June 30 of every third consecutive financial year, instead of annually.
Who Is Affected?
- Every individual holding an active DIN in India (approximately 3 million directors nationwide).
- Companies with multiple directors must track individual filing cycles for each director.
- Professionals (CAs, CSs, cost accountants) who certify KYC filings for clients.
Transition Rules: When Is Your Next Filing Due?
| Scenario | Next Filing Deadline |
|---|---|
| Filed KYC for FY 2024-25 | June 30, 2028 |
| Filed KYC for FY 2025-26 | June 30, 2029 |
| DIN allotted after April 1, 2025 (not held on March 31, 2025) | June 30, 2029 |
| Change in mobile, email, or residential address | Within 30 days of the change (regardless of triennial cycle) |
Critical March 31, 2026 Deadline: DIN Reactivation
Directors whose DINs were deactivated due to non-filing of KYC in previous years can get their DINs reactivated under the existing (old) provisions only until March 31, 2026. After this date, the new triennial framework takes over, and the old reactivation process will no longer be available.
If your DIN is currently deactivated, act before March 31, 2026. File Form DIR-3-KYC-Web immediately to reactivate it.
Simplified Form, Reduced Burden
- Routine triennial filings: No digital signature or professional certification required when details are unchanged.
- Event-based filings (change in mobile, email, or address): Digital signature and professional certification (CA, CS, or cost accountant) are mandatory. Must be filed within 30 days of the change.
- The revised DIR-3-KYC-Web form can be used for KYC compliance, updating contact details, and DIN reactivation.
Penalty for Non-Compliance
Failure to file within the prescribed deadline results in DIN deactivation and late fees under the Companies (Registration Offices and Fees) Rules, 2014. A deactivated DIN means you cannot sign board resolutions, file forms, or act as a director until reactivation.
Part B: TDS/TCS Correction Statements – Final Window Closing March 31, 2026
Why This Deadline Exists
The Income Tax Act, 1961 stands repealed effective April 1, 2026, under Section 536 of the new Income Tax Act, 2025. This creates a hard, non-extendable deadline: all TDS/TCS correction statements for older periods must be filed by March 31, 2026, because the legal authority under the old Act ceases to exist after that date.
Which Periods Are Affected?
Correction statements for the following periods will only be accepted until March 31, 2026:
- FY 2018-19 (Q4)
- FY 2019-20 to FY 2022-23 (all quarters, Q1 to Q4)
- FY 2023-24 (Q1 to Q3)
After March 31, 2026, the TRACES portal will permanently reject correction requests for these periods.
What Happens If You Miss It?
- Outstanding demands remain permanent: If there is a TDS/TCS demand raised for these periods due to PAN mismatches, incorrect amounts, or other errors, it cannot be corrected after March 31.
- Refund denials for deductees: If TDS was deducted but the statement has errors (wrong PAN, wrong amount), the deductee’s Form 26AS or AIS will not reflect the correct credit, leading to refund denials with no recourse.
- Interest and penalties: Uncorrected demands continue to attract interest, and there is no legal avenue to resolve them after the deadline.
New Rules from April 1, 2026
Under the Income Tax Act, 2025, the time limit for filing TDS/TCS correction statements is reduced from six years to two years. This means going forward, you will have a much shorter window to fix errors in TDS/TCS returns.
Action Steps for Deductors and Collectors
- Login to the TRACES portal (tdscpc.gov.in) and review all outstanding demands.
- Check for PAN mismatches, incorrect deduction amounts, or wrong section codes in statements from FY 2018-19 to FY 2023-24 (Q3).
- File correction statements for all identified errors before March 31, 2026.
- Inform deductees (employees, vendors) to verify their Form 26AS/AIS and flag any discrepancies immediately.
Practical Implications
For CA Professionals:
Send urgent advisories to all clients with deactivated DINs and pending TDS/TCS demands. The DIN reactivation window and TDS correction window both close on March 31. Prioritize clients with multiple directorships and businesses with high-volume TDS deductions.
For Founders and Startups:
Check if any of your directors have deactivated DINs. A deactivated DIN can block critical filings (annual returns, board resolution filings) and create complications during fundraising due diligence. For TDS, review your TRACES dashboard for any pending correction requests from FY 2018-19 onwards.
For MSME Owners:
If you deduct TDS on rent, professional fees, or contractor payments, verify that your TDS statements for the past five years are error-free. After March 31, you lose the ability to correct mistakes that could result in penalties or credit issues for your vendors.
Summary: Your March 31 Action Checklist
| Action | Authority | Deadline | Risk If Missed |
|---|---|---|---|
| DIN Reactivation (if deactivated) | MCA, Rule 12A | March 31, 2026 | Old reactivation process unavailable |
| Director KYC Status Review | MCA, G.S.R. 943(E) | March 31, 2026 | DIN deactivation, blocked filings |
| TDS/TCS Correction (FY 2018-19 to 2023-24 Q3) | CBDT, Income Tax Act 2025 s.536 | March 31, 2026 | Permanent uncorrectable demands |
| Update Internal Compliance Calendar | MCA + CBDT | Before April 1, 2026 | Missed triennial KYC deadlines |
Next Steps
Both of these deadlines are hard cutoffs with no extensions. The DIN reactivation window under the old rules closes permanently on March 31. The TDS/TCS correction window closes because the underlying statute is being repealed. Act now to avoid permanent compliance gaps that cannot be fixed later.
