Understanding GST return filing
Everything below is written for GST-registered businesses — which returns to file, when, how the monthly and quarterly options work, and what late filing costs.
What does GST return filing involve?
Every GST-registered business files returns reporting its sales, the tax it owes, and the input tax credit it's claiming. The two main returns are GSTR-1, which reports outward supplies invoice by invoice, and GSTR-3B, a summary return with which the tax is paid.
Returns are filed monthly, or quarterly for smaller businesses under the QRMP scheme, and an annual return at the end of the year. They have to be filed even for periods with no sales.
The key terms
The main returns and schemes:
- GSTR-1
- Details of outward supplies, filed monthly by the 11th, or quarterly under QRMP. It feeds your customers' input tax credit.
- GSTR-3B
- A summary return of sales, credit, and tax payable, filed with the tax payment — monthly by the 20th, or quarterly by the 22nd or 24th depending on the state.
- QRMP scheme
- Businesses with turnover up to ₹5 crore can file quarterly, paying tax monthly, and use the Invoice Furnishing Facility to report B2B invoices monthly.
- GSTR-2B
- An auto-generated statement of credit available from suppliers' filings, which your credit claim should match.
- Auto-populated liability
- Tax liability in GSTR-3B is increasingly auto-populated from GSTR-1, with corrections made through the GSTR-1 amendment route rather than by editing GSTR-3B.
- Late fee and interest
- A late fee applies for each day a return is late, and interest at 18% a year on tax paid late.
- Three-year time bar
- Returns generally can't be filed after three years from their due date, so old gaps become permanent.
A simple example
A Hyderabad electronics retailer with ₹3 crore turnover opts for QRMP. Each month in the quarter, it reports B2B invoices through the Invoice Furnishing Facility so its business customers get credit, and pays tax using the monthly challan. At the end of the quarter, it files GSTR-1 and GSTR-3B — the latter by the 22nd, as Telangana falls in that group — after matching its purchase credit to GSTR-2B.
Why it matters
GST returns are the core of GST compliance:
- Late fees add up
- Every day of delay adds a late fee, even for nil returns.
- Interest on late tax
- Tax paid late carries interest at 18% a year.
- Customers lose credit
- If you don't file GSTR-1, your customers can't claim credit, which damages relationships.
- E-way bills blocked
- Businesses that miss returns for a period can be blocked from generating e-way bills.
- Suspension and cancellation
- Not filing returns for a continuous period can lead to suspension or cancellation of registration.
- Mismatches trigger notices
- Differences between GSTR-1, GSTR-3B, and GSTR-2B are picked up automatically.
- Time bar
- Returns not filed within three years of the due date can't be filed at all.
Who is this for?
- Every regular GST-registered business
- Small businesses deciding between monthly filing and QRMP
- E-commerce sellers with marketplace sales
- Businesses with multiple GSTINs across states
- Businesses that have fallen behind on returns
Composition taxpayers file different, simpler returns. We handle those too.
Monthly filing vs. QRMP
For businesses with turnover up to ₹5 crore:
| Aspect | Monthly | QRMP (quarterly) |
|---|---|---|
| Eligibility | All taxpayers | Turnover up to ₹5 crore |
| GSTR-1 | Monthly, by the 11th | Quarterly, with optional monthly IFF for B2B invoices |
| GSTR-3B | Monthly, by the 20th | Quarterly, by the 22nd or 24th depending on state |
| Tax payment | Monthly, with GSTR-3B | Monthly by challan, then quarterly return |
| Suits | Larger or B2B-heavy businesses | Smaller businesses wanting fewer returns |

—FAQ
Questions business owners actually ask us
Yes. Nil returns must be filed for every period while you're registered. Late nil returns attract a smaller late fee, but it still adds up.
