1. Introduction
GST is a self-assessment based law. The registered person is primarily responsible to determine taxability, classify supplies, issue proper documents, report outward supplies, claim eligible ITC, discharge tax liability, file returns, maintain records and reconcile annual figures. The return system is not merely a filing formality; it is the legal trail through which outward liability, ITC, tax payment, TDS, TCS, annual reconciliation and departmental scrutiny are built.
The core return provisions are contained in section 37 for outward supply details, section 39 for periodical returns, section 44 for annual return, section 47 for late fee and section 50 for interest. Section 39 also provides that a registered person required to file a return must file it even where there are no supplies in the tax period, and returns cannot generally be furnished after expiry of three years from the relevant due date.

The GST portal confirms GSTR-1 due dates as 11th for monthly and 13th after quarter for quarterly filing, and GSTR-3B due dates as 20th for monthly and 22nd/24th after quarter for QRMP taxpayers. Composition taxpayers must file CMP-08 by 18th after the quarter and GSTR-4 by 30th June after the financial year.
5. Regular Taxpayer Compliance
5.1 GSTR-1: outward supply reporting
GSTR-1 contains invoice-wise and consolidated details of outward supplies. It includes B2B invoices, B2C large invoices, exports, debit notes, credit notes, amendments, advances, HSN summary and document summary.
Important practical points:
| Point | Compliance impact |
| Invoice reporting | B2B invoice details flow to recipient’s GSTR-2A/2B |
| Amendments | To be handled through amendment tables or GSTR-1A for current period |
| E-invoice | E-invoice data auto-populates into GSTR-1, but taxpayer must verify before filing |
| HSN reporting | HSN summary must be prepared from books and invoices |
| Three-year bar | GSTR-1 cannot generally be filed after three years from due date |
Section 37 imposes the three-year outer restriction for furnishing outward supply details, subject to notified relaxation.
5.2 GSTR-1A: current-period correction before GSTR-3B
GSTR-1A is an optional facility introduced to amend or add current tax-period outward supply details after filing GSTR-1/IFF but before filing GSTR-3B. The practical importance is high because liability flowing from GSTR-1/1A/IFF is used for GSTR-3B. The portal advisory noted that GSTR-1A allows correction before GSTR-3B and that auto-populated liability in GSTR-3B was to become non-editable from the July 2025 tax period, with corrections to be routed through GSTR-1A.
5.3 GSTR-3B: summary return and tax payment
GSTR-3B is the monthly/quarterly return for declaring outward tax liability, eligible ITC, ITC reversals, exempt/non-GST supplies, RCM liability and tax paid. The GST portal describes GSTR-3B as a simplified summary return for declaring summary GST liabilities for a tax period.
Key reconciliations before filing GSTR-3B:
| Reconciliation | Why important |
| GSTR-1 vs GSTR-3B outward tax | Avoid DRC-01B mismatch |
| GSTR-2B vs ITC claimed in GSTR-3B | Avoid DRC-01C / ITC dispute |
| Books vs GSTR-3B | Avoid under-reporting or excess ITC |
| RCM register vs GSTR-3B | Ensure RCM paid in cash and ITC claimed correctly |
| Credit notes vs tax adjustment | Ensure section 34 conditions are met |
6. QRMP Scheme
The Quarterly Return Monthly Payment Scheme is available to eligible taxpayers having AATO up to ₹5 crore. Under QRMP, GSTR-1 and GSTR-3B are filed quarterly, but tax is paid monthly for the first two months of the quarter through PMT-06. The GST portal states that QRMP is for eligible taxpayers to file GSTR-1 and GSTR-3B quarterly while paying tax monthly, and eligibility requires AATO up to ₹5 crore and filing of the latest GSTR-3B.

Annual GSTR-9 / GSTR-9C as applicable
PMT-06 under QRMP can be paid through the fixed sum method or self-assessment method; GSTN’s QRMP FAQ states that the due date for challan payment is the 25th of the next month.
7. Composition Scheme Compliance
Composition levy under section 10 is meant to simplify compliance for small taxpayers. Composition taxpayers do not collect tax separately from customers, cannot issue tax invoice, generally cannot claim ITC and pay tax at prescribed composition rates. Rule 7 provides composition levy rates, including 0.5% under section 10(1)/(2) for eligible suppliers and 3% under section 10(2A) for eligible service suppliers; SGST/UTGST applies similarly.
Composition compliance table
| Form | Purpose | Due date | Remarks |
| CMP-02 | Intimation to opt into composition | Before start of financial year, as applicable | Online |
| ITC-03 | Reversal of ITC on opting into composition / exemption | As prescribed | Online/offline utility |
| CMP-08 | Quarterly tax payment statement | 18th after quarter | Mandatory |
| GSTR-4 | Annual return | 30th June after FY | Mandatory for persons who were composition taxpayers even for part of FY |
Rule 62 provides that composition taxpayers furnish CMP-08 by the 18th after the quarter and GSTR-4 by 30th June following the end of the financial year.
8. Annual Return: GSTR-9
GSTR-9 is the consolidated annual return for regular taxpayers. It captures annual details of outward supplies, inward supplies, ITC availed/reversed, tax paid, demands/refunds, HSN summary and transactions of the previous year reported in the next year.
Who files GSTR-9?
| Category | GSTR-9 applicability |
| Regular taxpayer | Applicable, subject to exemption notifications |
| Composition taxpayer | GSTR-4, not GSTR-9 |
| ISD | Not in ISD capacity |
| TDS/TCS deductor/operator | Separate forms apply |
| Casual taxable person | Excluded under Rule 80 |
| Non-resident taxable person | Excluded under Rule 80 |
Rule 80 provides that every registered person, other than specified excluded categories, shall furnish annual return in GSTR-9 by 31st December following the end of the financial year.

The GST portal states that from FY 2023-24 onwards, portal-computed GSTR-9 values are based on GSTR-1, GSTR-3B and GSTR-2B, and the computed summary/Table 8A excel can be downloaded.
9. Reconciliation Statement: GSTR-9C
GSTR-9C is a self-certified reconciliation statement reconciling turnover, tax paid and ITC as per annual return with audited financial statements. Rule 80(3) provides that taxpayers with aggregate turnover exceeding ₹5 crore during a financial year must furnish GSTR-9C along with GSTR-9 by 31st December following the end of the financial year.
GSTR-9C is required where:
| Condition | Result |
| Aggregate turnover exceeds ₹5 crore | GSTR-9C applicable |
| Aggregate turnover does not exceed ₹5 crore | GSTR-9C not applicable |
| GSTR-9C applicable but not filed with GSTR-9 | Annual return is incomplete for late fee purposes |
CBIC Circular No. 246/03/2025-GST clarified that where GSTR-9C is required, annual return under section 44 is complete only when both GSTR-9 and GSTR-9C are filed; late fee is computed up to the date of filing the complete annual return, and late fee is not separately leviable for GSTR-9 and GSTR-9C.
GSTN’s FY 2024-25 FAQs also explain GSTR-9/9C reporting issues such as RCM paid in a later year, ITC reversal reporting, Table 12/13 reporting and late fee reporting in GSTR-9C.
10. Special Category GST Returns
| Form | Taxpayer | Purpose | Due date | Notes |
| GSTR-5 | Non-resident taxable person | Return of supplies, ITC and tax | 13 days after month-end or 7 days after registration period ends, whichever earlier | Section 39(5) |
| GSTR-5A | OIDAR supplier | OIDAR tax return | 20th of next month | GST portal due date |
| GSTR-6 | ISD | Distribution of ITC | 13th of next month | Section 39(4) / portal |
| GSTR-7 | TDS deductor | TDS return | 10th of next month | Nil return also required from notified period |
| GSTR-8 | ECO collecting TCS | TCS statement | 10th of next month | Section 52 |
| GSTR-9B | ECO collecting TCS | Annual TCS statement | Before 31st December after FY | Section 52(5) |
| GSTR-11 | UIN holder | Inward supplies for refund | Before refund | File where refund claimed |
Section 52 requires an ECO collecting TCS to pay the amount within 10 days after month-end, furnish monthly statement within 10 days after month-end, and furnish annual statement before 31st December following the end of the financial year.
11. Job Work Compliance: ITC-04
Where a principal sends inputs or capital goods to a job worker without payment of tax, details are required in Form GST ITC-04.
| Principal’s turnover in preceding FY | ITC-04 frequency | Due date |
| More than ₹5 crore | Half-yearly: April–September and October–March | 25th of month succeeding the half-year |
| Up to ₹5 crore | Annual | 25th April after financial year |
Rule 45 provides that ITC-04 must be furnished by the 25th day of the month succeeding the specified period; specified period is six months for principals with turnover above ₹5 crore and financial year in other cases.
12. Online Filing vs Offline Utility vs Manual Filing
| Compliance | Online / manual position |
| GST returns | Filed electronically on GST common portal |
| Offline utility | Used for preparation/upload in forms like GSTR-1, GSTR-3B, GSTR-9, GSTR-9C, ITC-04 etc., where enabled |
| Nil GSTR-1 / GSTR-3B | Can be filed through SMS subject to conditions |
| GSTR-7A | System-generated certificate |
| Paper/manual physical filing | Generally not applicable for GST returns |
| DRC-03, refund, registration, amendment, cancellation | Filed electronically on portal |
Thus, in GST, “manual” normally means preparation using an offline tool and uploading data on the portal. It does not mean paper filing of return at the department counter, unless a specific exceptional manual procedure is separately notified.
13. Late Fee under GST
Section 47 provides late fee of ₹100 per day under CGST for delay in GSTR-1/returns under sections 39, 45 and 52, subject to a maximum of ₹5,000 under CGST. A similar amount applies under SGST/UTGST, so normal combined late fee is usually double. For annual return under section 44, section 47(2) provides ₹100 per day under CGST, subject to maximum of 0.25% of turnover in the State/UT; SGST/UTGST applies similarly.
Rationalised late fee caps for major returns
| Return | Class of taxpayer | Common effective maximum late fee, CGST + SGST |
| GSTR-1 / GSTR-3B | Nil outward supply / nil tax liability | ₹500 |
| GSTR-1 / GSTR-3B | AATO up to ₹1.5 crore | ₹2,000 |
| GSTR-1 / GSTR-3B | AATO above ₹1.5 crore and up to ₹5 crore | ₹5,000 |
| GSTR-1 / GSTR-3B | AATO above ₹5 crore | ₹10,000 |
| GSTR-4 | Nil tax liability | ₹500 |
| GSTR-4 | Other composition taxpayers | ₹2,000 |
| GSTR-7 | TDS deductor | ₹50 per day, generally capped at ₹2,000 combined |
| GSTR-9 / 9C | Annual return | Section 47(2) basis; GSTR-9C delay counted as incomplete annual return where applicable |
CBIC’s notification list records Notifications 19/2021 to 22/2021 as rationalising late fee for GSTR-3B, GSTR-1, GSTR-4 and GSTR-7 respectively. For GSTR-9C, CBIC Circular 246/03/2025 clarifies that late fee applies for delay in filing the complete annual return where GSTR-9C is required.
14. Interest under GST
| Default | Provision | Interest principle |
| Delayed payment of tax | Section 50(1) | Interest payable for period tax remains unpaid; rate notified up to 18% |
| Delayed GSTR-3B where tax declared late | Proviso to section 50(1) | Interest generally on net cash liability if return filed late, except where proceedings under section 73/74/74A have commenced |
| Wrong ITC availed and utilised | Section 50(3) | Interest payable on ITC wrongly availed and utilised; rate notified up to 24% |
| TDS not paid | Section 51(6) | Interest under section 50(1) |
| TCS mismatch addition | Section 52(11) | Interest from original due date till payment |
Section 50 states that delayed tax payment attracts interest and, for belated section 39 returns, interest is levied on the portion paid through electronic cash ledger, except where proceedings have commenced.
15. Penalty under GST
Penalty can arise for non-filing, incorrect filing, non-payment, wrong ITC, fake invoicing, non-issuance of invoice, suppression, fraud, failure to furnish information, or general contravention.
| Nature of default | Provision | Penalty |
| Tax short paid / not paid / erroneous refund / ITC wrongly availed or utilised, without fraud | Section 122(2)(a) | ₹10,000 or 10% of tax due, whichever higher (each) |
| Same default due to fraud, wilful misstatement or suppression | Section 122(2)(b) | ₹10,000 or tax due, whichever higher (each) |
| General contravention where no separate penalty provided | Section 125 | Up to ₹25,000 (each) |
| ECO fails to furnish information required by notice | Section 52(14) | Up to ₹25,000 (each) |
| Proceedings from FY 2024-25 onward | Section 74A | Unified demand framework; notice within 42 months from annual return due date / erroneous refund date; order within 12 months, extendable by 6 months |
Section 122 covers several offences including supply without invoice, false invoice, tax collected but not paid, ITC wrongly availed/utilised and other contraventions. Section 125 provides a general penalty up to ₹25,000 where no separate penalty is provided. Section 74A now provides a unified demand mechanism and requires notice within 42 months from the annual return due date or erroneous refund date.
16. Three-Year Time Limit for Filing GST Returns
GST law now restricts belated filing of returns/statements after three years from the due date for forms covered under sections 37, 39, 44 and 52. These include GSTR-1, GSTR-3B, GSTR-4, GSTR-5, GSTR-5A, GSTR-6, GSTR-7, GSTR-8 and GSTR-9. GSTN advisory material stated that the portal restriction would be implemented from the July 2025 tax period.
Practical effect

Late filing possible with late fee/interest
↓
Outer limit: 3 years from due date
↓
After 3 years: portal filing barred, unless Government notifies relaxation
17. Important Supporting Statements and Auto-Drafted Forms
| Form / statement | Nature | Used for |
| GSTR-2A | Dynamic auto-drafted statement | Supplier-wise inward supplies, may change as suppliers file/amend |
| GSTR-2B | Static ITC statement | ITC decision for GSTR-3B |
| GSTR-4A | Auto-drafted inward supply statement for composition taxpayer | Reference for GSTR-4 |
| GSTR-6A | Auto-drafted ISD inward statement | Reference for GSTR-6 |
| GSTR-7A | TDS certificate | Deductor/deductee record |
| Electronic cash ledger | Cash balance | Tax, interest, penalty, late fee payment |
| Electronic credit ledger | ITC balance | Output tax payment, subject to restrictions |
| Electronic liability register | Liability register | Track dues and payments |
GSTR-2B draws data from GSTR-1/1A/IFF, GSTR-5, GSTR-6 and import data, and is used for auto-population and ITC control in GSTR-3B.
18. Return Filing Risk Areas
| Risk area | Common mistake | Control |
| GSTR-1 vs books | Invoice missed or duplicated | Monthly sales register reconciliation |
| GSTR-1 vs GSTR-3B | Liability mismatch | File GSTR-1A before GSTR-3B where current-period correction needed |
| GSTR-2B vs ITC register | ITC claimed without 2B support | Vendor follow-up and ITC ageing |
| RCM | Liability not paid in cash | Maintain separate RCM register |
| Credit notes | Tax adjustment beyond time/without recipient reversal | Link every credit note to invoice |
| E-invoice | IRN not generated though applicable | Check turnover and document type |
| E-way bill | Movement not matching invoice | E-way bill vs invoice reconciliation |
| Annual return | GSTR-9 not matching books | Prepare annual reconciliation early |
| GSTR-9C | Turnover/ITC/tax reconciliation differences | Document reasons in reconciliation statement |
19. Suggested Monthly Compliance Checklist
| Date range | Action |
| 1st–5th | Close books, sales, purchase, RCM and expense ledgers |
| 5th–10th | Reconcile e-invoices, e-way bills and outward supply register |
| 10th–11th | File monthly GSTR-1 |
| 14th | Download and analyse GSTR-2B |
| 15th–18th | Finalise ITC, RCM, reversals, Rule 42/43 where applicable |
| 18th | CMP-08 for composition taxpayers |
| 20th | Monthly GSTR-3B |
| 25th | QRMP PMT-06 for first two months of quarter |
| 22nd/24th after quarter | QRMP GSTR-3B |
| 25th after ITC-04 period | ITC-04 where applicable |
20. Suggested Annual GST Compliance Checklist
| Period | Action |
| April–June | Finalise books and GST reconciliations for previous FY |
| July–September | Identify missed invoices, credit notes, debit notes, RCM, ITC issues |
| Up to 30 November | Rectify eligible omissions/inaccuracies for previous FY, subject to law |
| October–December | Prepare GSTR-9 and GSTR-9C |
| By 31 December | File GSTR-9 and GSTR-9C where applicable |
| Before audit/scrutiny | Keep reconciliation file: books, GSTR-1, GSTR-3B, 2B, 9, 9C, e-invoice, e-way bill |
21. Conclusion
GST compliance is now a data-linked compliance chain. GSTR-1, GSTR-1A, IFF, GSTR-3B, GSTR-2B, e-invoice, e-way bill, annual return and reconciliation statement operate together. A taxpayer should not treat return filing as isolated monthly work. Proper compliance requires classification, documentation, timely reporting, ITC control, RCM review, ledger matching and annual reconciliation.
The most important compliance discipline is this:
Correct invoice
+ Correct reporting in GSTR-1/1A
+ Correct ITC based on GSTR-2B
+ Correct tax payment in GSTR-3B
+ Correct annual reconciliation in GSTR-9/9C
= Strong GST compliance defence
