GST Return Compliance Deadline Last Chance Alert. 2025

If you still have old pending GST returns, this is your final reminder.
From 1 December 2025, the government will permanently close the filing window for certain old GST returns.

Meaning — once the date passes, you will never be able to file those returns again. No second chance, no reopening.

So, if you forgot or delayed any older GST return, this is the time to finish it.

Which GST Returns Will Be Blocked After 1 December 2025?

Here are the returns and periods that will close forever:

In simple words:
If you haven’t filed these specific returns for those months/years, you won’t be able to file them later at all.

Why You Should Not Ignore This

If you miss the deadline, you may face:

⚠️ Loss of Input Tax Credit (ITC)
⚠️ Penalties & interest
⚠️ GST compliance issues in future
⚠️ Problems during GST audit/scrutiny
⚠️ Vendor reconciliation mismatch

Even if the return belongs to an old period, not filing it can cause trouble later.

Why Government Is Doing This

The GST system is moving toward:

• Faster reporting

• Clean and accurate tax data

• Closing old pending filings

• Better compliance discipline

So the portal is clearing old backlog forever.

What You Should Do Now

To avoid any issues:

✔️ Log in to the GST portal
✔️ Check if any old return is pending
✔️ File all overdue returns immediately

Bottom Line

After that, you cannot file these old returns — ever.
