December is a crucial month for taxpayers, bank customers, and pensioners.
While some deadlines ended in November, several important compliance dates remain this month.
Missing these could lead to penalties, transaction disruptions, or delays in services.
Here’s a clear guide to what you need to do.
Key Tax Deadlines
New ITR Filing Deadline for Tax Audit Cases
The Income Tax Department has extended the tax audit ITR filing deadline from October 31 to December 10, 2025.
This extension helps taxpayers whose returns require audits and additional financial disclosures to file without rush.
PAN-Aadhaar Linking by December 31, 2025
If you got your Aadhaar on or before October 1, 2024, you must link it with your PAN by December 31.
Failure to do so will make your PAN inoperative, affecting banking transactions, ITR filing, investments, and other financial services.
Belated and Revised ITR Filing
December 31 is also the final date to file:
Belated Returns: For those who missed the original ITR deadline. Late fees apply.
Revised Returns: To correct errors or omissions in previously filed returns.
After this date, only the Updated Return (ITR-U) option remains, which comes with higher penalties — 25% to 50% extra on tax and interest.
Filing before December 31 is the most cost-efficient way to settle your taxes.
Banking Updates
SBI Discontinues mCASH
From November 30, 2025, SBI customers can no longer use mCASH to send money without registering beneficiaries.
Customers should now use UPI, IMPS, NEFT, or RTGS for secure transactions.
Pension and Government Employee Compliance
Life Certificate Submission Deadline Passed
The last date to submit the Jeevan Pramaan Patra (Life Certificate) was November 30, 2025.
Pensioners who missed this may face a temporary suspension of pension payments.
Switching from NPS to UPS
The deadline to switch from National Pension System (NPS) to the Unified Pension Scheme (UPS) also ended on November 30.
UPS offers features of both NPS and the Old Pension Scheme, including a guaranteed pension.
Note: The switch can only be availed once, but NPS members can return to it later if desired.
Why December Is Important
December 2025 is critical for managing your finances:
Linking PAN with Aadhaar ensures uninterrupted banking and tax filing
Filing belated or revised ITRs avoids higher penalties
Following banking and pension deadlines prevents service disruptions
Completing these tasks on time keeps your accounts, taxes, and pensions running smoothly into 2026.
