Prepare the overdue return, review the portal-calculated tax, interest and late fee, arrange payment through the applicable ledger or challan workflow, file with the authorised signatory, and retain the acknowledgement and payment records.
Do not apply a late-fee figure, interest rate or waiver from an older period to a current return without checking the law and notifications that cover your form and period. GST consequences depend on the return type, filing frequency, liability, payment history, taxpayer category and any notification in force.

Start by identifying exactly what is overdue
“GST overdue” can describe several different situations. The correct remedy depends on which one applies:
- A return has not been prepared or filed by its due date.
- A return is prepared, but the tax shown in it has not been paid.
- Money was paid into the electronic cash ledger, but the return was not filed.
- A return was filed and the portal’s interest or late-fee calculation appears wrong.
- A notice or system-generated default communication has been issued after non-filing.
Before changing anything in the portal, record the GSTIN, return form, financial year, tax period, filing frequency, due date shown by the portal, payment date (if any), cash-ledger balance and current filing status. A historic period may be governed by a different notification from a current period, and an extension may have changed the original due date.
#1 Best Overall
Common forms do not share one universal process
| Return or situation | What is established | What you must verify |
|---|---|---|
| GSTR-1 | The GST Portal says a filer who misses the due date receives a system-generated Form 3A defaulter notice. | The applicable due date, filing frequency, period-specific extension and any response requirement. |
| GSTR-3B | Interest is calculated using the liability discharged and tax-liability breakup and is reflected for collection in a subsequent GSTR-3B. | The portal’s interest computation, tax actually paid, cash-ledger history and any recomputation option. |
| Annual return (for example, GSTR-9) | Some waivers have been issued for specified years and conditions. | The financial year, eligibility conditions, filing of any required GSTR-9C and the notification covering that year. |
| GSTR-7 or another form | The payment and filing sequence is documented in that form’s current GST Portal manual. | That form’s own due date, challan and ledger instructions; do not copy a GSTR-7 workflow automatically to another return. |
Check the due date and any extension before calculating a charge
Open the relevant return tile on the GST Portal, select the financial year and period, and note the due date displayed for that form. GST Portal guidance for GSTR-1 specifically states that due dates can be changed by government notification. The date originally shown in a calendar, accounting package or old article may therefore be superseded.
Look for a notification or order that covers your exact form, tax period, state or taxpayer category. A notification that extends one return or grants a waiver for one financial year does not automatically change every GST deadline. Save a copy of the applicable notification with your compliance records.
Separate a late return from a late payment
A return can be late even when the tax was deposited in advance. Conversely, a return may have been filed while tax remained unpaid. The portal’s ledgers and filed-return details show which event occurred and when. Interest, late fee and any notice treatment can differ between those cases, so do not use the date of a challan as a substitute for the filing date.

Prepare the overdue return for the correct period
- Select the exact return and period. Confirm the GSTIN, financial year, month or quarter, filing frequency and return type before entering figures. Do not amend a different period to compensate for a missed one.
- Reconcile source records. Match sales, purchases, credit and debit notes, reverse-charge transactions, exports, exempt supplies and tax payments to your books and supporting documents for that period.
- Complete the portal tables. Save each section and resolve validation errors. If the portal has auto-populated data, compare it with your records rather than assuming it is complete.
- Review the liability summary. Check tax by head, input-tax-credit adjustments, interest and late fee shown by the system. Confirm that the figures are for the selected period, not an adjacent month or quarter.
- Generate or download a draft summary. Have the person responsible for the books review the draft before payment and filing. Preserve the draft and reconciliation if the figures later need to be explained.
Review interest and late fee before paying
There is no single current GST late-fee or interest figure that applies to every return. The amount may depend on the form, whether the return has nil or non-nil liability, the number of delayed days, tax paid and the notifications applicable to the period. The portal’s computed amount is the starting point, but a material discrepancy should be investigated rather than paid blindly.
Delayed GSTR-3B interest
GSTN states that delayed GSTR-3B interest is calculated using the liability discharged and the tax-liability breakup, with the amount reflected for collection in a subsequent GSTR-3B. The detailed breakdown is available in the system-generated GSTR-3B PDF.
GSTN’s March 2026 advisory identifies a possible issue for some taxpayers where the February 2026 period appeared in the March 2026 period. The issue involved failure to account for the minimum electronic cash-ledger balance under Rule 88B(1). If your portal calculation shows that discrepancy, open the system-generated PDF and compare the breakup with your payment and ledger records. The advisory says the taxpayer may click the “RE-COMPUTE INTEREST” button under Table 5.1 of GSTR-3B and use the revised PDF figures. The advisory is educational; applicable law, rules and notifications remain controlling.
Historical figures are not a current rate card
A CBIC explanatory document published in 2019 described historical GSTR-3B late-fee figures from October 2017 onward: ₹20 per day for the nil-liability case described there and ₹50 per day for the non-nil case described there. Those figures belong to the circumstances and period covered by that document. They are not a universal current rate for every delayed GSTR-3B or other return.

Likewise, a waiver is limited by its wording. CBIC Circular No. 246/03/2025-GST described a conditional waiver of excess late fee for specified delayed annual returns through financial year 2022–23 when the required GSTR-9C was furnished by 31 March 2025. That deadline has passed. It does not establish a waiver for later years, other forms or taxpayers who did not meet the stated condition.
Pay through the workflow for your form
Use the return’s current GST Portal instructions for payment. The sequence below is documented specifically for GSTR-7 and illustrates the type of checks required; it is not a universal procedure for every GST return.
Rank #4
- Check the electronic cash ledger. Confirm whether the available balance covers the amount required for the return, including the portal-calculated components that must be paid in cash.
- Create a challan for any shortfall. If the balance is insufficient, generate a challan for the amount not covered. Verify the tax head and amount before submitting it.
- Choose an available payment channel. The GSTR-7 manual lists electronic payment, over-the-counter payment and NEFT/RTGS options. Availability and bank processing times can vary, so allow time for the amount to appear in the ledger.
- Confirm credit to the ledger. Do not assume that a payment instruction equals a credited balance. Check the electronic cash ledger and retain the challan, bank reference and transaction confirmation.
- Offset the liability and file. Once the required balance is available, offset the liability in the return and complete filing using the listed authorised-signatory process.
For another return, follow its own portal manual and the options displayed for your registration. A GSTR-7 payment path should not be copied to GSTR-1, GSTR-3B, an annual return or a specialised form without confirmation.
Complete filing and preserve proof
Payment alone does not necessarily file a return. After offsetting the liability, submit the return with the authorised signatory method available to the registration. Wait for the filing acknowledgement or reference number and check that the status changes to filed. Download the filed-return PDF, payment challan, ledger entries, interest or late-fee calculation and any notice or response for the same period.
Keep a dated compliance file containing the return data, reconciliation, invoices or schedules supporting material adjustments, challan and bank confirmation, acknowledgement and correspondence. These records help if the portal later recalculates interest or an officer asks how the liability was settled.

What to do when the portal shows a notice or default
GSTR-1 Form 3A notice
The GST Portal states that a GSTR-1 filer who misses the due date receives a system-generated Form 3A defaulter notice. Treat that as a form-specific consequence. Read the notice for the period, required action and response deadline, then file the outstanding return and follow the notice instructions. Do not assume that every GST form generates Form 3A or that the same response process applies elsewhere.
A disputed interest or late-fee amount
First compare the portal amount with the system-generated return PDF, payment dates and cash-ledger entries. For a delayed GSTR-3B, use the “RE-COMPUTE INTEREST” function where the March 2026 advisory applies and retain both the original and revised PDFs. If the discrepancy remains, document the calculation and seek advice from a qualified Indian GST practitioner before filing a representation or making a second payment.
An amount you cannot currently fund
Do not leave the return unfiled merely because the payment is difficult. Prepare the return, identify the exact tax and statutory additions shown by the portal, and obtain professional advice on the lawful payment and compliance options available for your facts. Avoid using a different period, an incorrect tax head or an unsupported waiver to force the return through.

- Using an old article’s rate: historical CBIC figures and past waivers are not current universal rules.
- Checking only the original calendar: a government notification may have extended the due date.
- Paying without selecting the correct period: a challan or ledger credit does not repair a return filed for the wrong month or year.
- Assuming payment equals filing: confirm the final filed status and acknowledgement.
- Copying another form’s workflow: GSTR-7 instructions illustrate one process, not every return.
- Ignoring the liability breakup: interest may depend on the amount actually discharged and the tax-liability details.
- Relying on a notice assumption: a consequence established for GSTR-1 should not be extended to other forms without evidence.
- Failing to retain proof: keep PDFs, challans, ledger records and transaction references after the portal accepts the filing.
A practical decision checklist
- Have you written down the GSTIN, form, financial year and exact tax period?
- Does the portal show the original due date, a revised due date or an extension notification?
- Is the problem a late return, an unpaid liability, or both?
- Do your books reconcile with the portal’s auto-populated information and return tables?
- Have you reviewed tax, interest and late fee in the correct period’s summary and PDF?
- For delayed GSTR-3B, have you checked whether the March 2026 recomputation guidance applies to your February 2026 period?
- Does the electronic cash ledger cover the amount, or must you generate a challan?
- Have you followed the payment workflow specific to this return?
- Did the authorised signatory complete filing, and did you save the acknowledgement?
- Is there a notice, disputed calculation or historic-period condition that requires a qualified GST practitioner?
When professional help is appropriate
Consult a qualified Indian GST practitioner when the return covers a historic period, the portal and books disagree materially, a waiver’s eligibility is uncertain, a notice has been issued, several periods are overdue, or payment was made under the wrong head or GSTIN. A precise liability cannot be calculated from the fact that a return is “overdue” alone; the form, period, taxpayer facts, payment history and applicable notifications are all necessary.
