What is GST return filing?
GST return filing is the periodic submission of prescribed forms - such as GSTR-1 for outward supplies and GSTR-3B for summary tax liability - through which a GST-registered business reports its sales, purchases, input tax credit, and tax payable to the government.
Every regular GSTIN must file returns even in nil months. Filing is how your buyers see their credit, your ITC is claimed, and your liability is paid on record.
If you operate in multiple states, each GSTIN has its own filing cycle. That means deadlines, reconciliations, and notice risk multiply unless one team owns the calendar.

THE RULES CHANGED
GST filing in 2026 is stricter than what you remember
Three changes from 2025 reshaped how returns work. Most businesses found out the hard way.
Hard-locked GSTR-3B values
From July 2025, auto-populated liability in GSTR-3B is locked. Corrections must flow through GSTR-1A before filing.
Non-editable Table 3.2
From November 2025, inter-state supply values auto-populated from GSTR-1 are final. Accuracy at GSTR-1 stage is everything.
The 3-year filing bar
Returns can no longer be filed after 3 years from their due date. Old pending returns now lapse permanently.
System-driven mismatch notices
GSTR-1 vs 3B and ITC vs 2B mismatches trigger automated DRC-01C notices. Reconciliation is no longer optional.

GSTR-1 vs 3B mismatch
System auto-flags the difference and issues DRC-01C.

Excess ITC claimed vs 2B

Skipped nil returns
Late fees accrue even at zero activity and the portal blocks future filings.

The risk
QRMP misunderstanding
Businesses file quarterly but forget monthly PMT-06 tax payment.
How we handle it
We manage the payment calendar alongside returns.
The risk
Backlog past 3 years
Returns lapse permanently and compliance rating suffers.

Fast answersExpert support
- GST return filing is the periodic submission of prescribed GST forms through which a registered business reports sales, purchases, input tax credit, and tax payable to the government.
- A regular GST-registered business usually files GSTR-1 for outward supplies and GSTR-3B for summary tax liability. Depending on turnover and activity, annual returns such as GSTR-9 and reconciliation in GSTR-9C may also apply.
- Monthly GSTR-1 is generally due on the 11th of the next month, while monthly GSTR-3B is generally due on the 20th of the next month. QRMP due dates differ by return type and state.
- The QRMP scheme allows eligible businesses with turnover up to Rs.5 crore to file some GST returns quarterly while paying tax monthly through PMT-06.
- Yes. Nil GST returns are mandatory even when there is no sales or purchase activity for the tax period. Skipping nil returns can still trigger late fees and block future filings.
- GST late fees apply per day under CGST and SGST and are capped as notified for the return type. Nil returns have lower caps, while non-nil returns can attract higher capped late fees.
- Late payment of GST tax generally attracts interest at 18% per annum, calculated for the delay period on the tax amount paid late.
- GSTR-9 is the annual GST return that consolidates outward supplies, inward supplies, input tax credit, and tax paid for the financial year. Applicability depends on turnover and notified exemptions.
- GSTR-1 reports invoice-level outward supplies, while GSTR-3B reports summary tax liability, input tax credit, and tax payment for the period.
- A DRC-01C notice is issued when the system detects mismatch between tax liability reported in GSTR-1 and tax paid through GSTR-3B. It requires a reply or corrective action.
- Old GST returns can be filed only within the permitted statutory window. From the July 2025 period onward, returns cannot be filed after three years from the due date.
- From 2025-26, auto-populated GSTR-3B liability became harder to edit, Table 3.2 became non-editable from November 2025, and corrections must flow through upstream return data such as GSTR-1A.
- Yes. GST compliance is GSTIN-wise, so a business with registrations in multiple states must file returns separately for each GSTIN.
- Yes. ComplyLocal can work with Tally, Zoho Books, Busy, Excel, or other accounting exports to prepare, reconcile, and file GST returns.
