As we step into September, it is not just the festive season that comes knocking, but your finances need attention too. From switching your Unified Pension Scheme (UPS) to the National Pension System (NPS) , filing income tax returns ( ITR) by due date September 15, keeping an eye on special bank fixed deposits (FDs), to paying the second instalment of advance tax, this month is packed with crucial financial deadlines. Missing any of these could lead to penalties or lost benefits.

Here is a quick guide of what to track and get done before the month ends:

NPS to UPS switch

The Centre has decided to allow its employees who have selected UPS a one-time, one-way switch facility to NPS. Central government employees can switch to the UPS before September 30, 2025, for assured payouts and several benefits. "This switch facility may be exercised by UPS optees any time not later than one year prior to the date of superannuation or three months prior to the deemed date of retirement in case of voluntary retirement, as applicable. Similar provisions will be made for resignation and cases of Rule 56J, with minor modifications as necessary. If switch facility not exercised as per aforesaid timelines, the employee shall continue under UPS by default," the notification read. Read more

Income tax return filing deadline

Individuals and HUFs who do not need to get their accounts audited have until September 15, 2025, to file their ITR. The ITR filing deadline for FY 2024–25 was extended from July 31, 2025, to mid September this year. Read more

Advance tax deadline (2nd instalment)

The second instalment of advance tax for the financial year 2025–26 (Assessment Year 2026–27) is due on 15 September 2025, by which 45% of your total estimated tax liability must be paid (after deducting what’s already paid).

Special bank fixed deposit (FD) deadline

Indian Bank and IDBI Bank are among the several banks offering special fixed deposit (FD) schemes to their customers. The deadline to invest in these special FDs is September 30, 2025.

Cashless hospitalisation services

Starting September 1, hospitals across the country will suspend cashless hospitalisation services for policyholders of Bajaj Allianz General Insurance, following a directive from the Association of Healthcare Providers India (AHPI). This means patients with health insurance from Bajaj Allianz may need to pay hospital bills upfront and seek reimbursement later, instead of availing direct cashless treatment. AHPI has also issued notice to CARE Health Insurance. Read more
