LPG Price Update, Aadhaar-PAN Linking and Belated ITR Filing Deadline: Key Financial Changes in Dec 2025

December 2025 brings several important updates that may affect households, travellers, taxpayers and investors. From the monthly reset of LPG and ATF prices to critical tax deadlines and changes in stock market indices, here is a simple overview of what to expect.

LPG Prices to Be Revised on 1 December

Cooking gas prices will undergo their monthly revision on 1 December. Oil marketing companies adjust LPG prices at the start of every month based on global energy trends and currency movements.

Last month, commercial LPG cylinders saw a small price cut. Whether the December update brings relief or increases costs for families will be known on Sunday morning. For many households, any change in LPG rates directly influences grocery planning and monthly budgets.

ATF Price Update Due

Aviation Turbine Fuel prices, revised on the same monthly schedule as LPG, will also be updated on 1 December. ATF prices play a major role in airline operating costs. Even a small change can affect airfares, especially during the busy holiday season. With travel demand rising, December fares may reflect any adjustment in ATF rates.

Aadhaar–PAN Linking Deadline Approaches

Individuals who received their Aadhaar on or before 1 October 2024 must link their PAN with Aadhaar by 31 December 2025. PAN cards not linked by this date will become inoperable.

This deadline is important for taxpayers, as an inactive PAN can disrupt banking transactions, tax filings and financial services.

BSE Index Reconstitution in December

A major reshuffle of key Bombay Stock Exchange indices will take effect in December. The update includes changes to benchmark indices such as the SENSEX, BSE 100 and BSE Bankex.

InterGlobe Aviation will join the SENSEX from 22 December 2025. At the same time, Tata Motors Passenger Vehicles will be removed. These changes may influence index-linked funds and market sentiment.

Final Deadline for Belated or Revised ITR Filing

For all taxpayers, 31 December 2025 is the absolute final date to file a belated tax return for FY 2024–25 or to correct an earlier return.

• Belated Return: Allowed if the original deadline was missed, but attracts a late fee of up to ₹5,000 (₹1,000 for income below ₹5 lakh).
• Revised Return: Used to correct mistakes in a previously filed return, but must also be submitted by 31 December.

After this date, the only option left is filing an Updated Return (ITR-U), which involves higher penalty tax.
