For India’s GST, there is no single universal late-fee number. The amount depends on the return form, tax period, applicable due date or extension, days of delay, nil or non-nil status, turnover category, State or Union territory component, and any notification or waiver for that period. The reliable method is to let the GST Portal calculate the liability for the exact return, then verify the form-specific rate and cap before paying. Late fee is separate from interest on tax paid late.
What you need before calculating a GST late fee
Gather these facts for the registration and return in question. A calculation made without them can apply the wrong cap or even the wrong legal regime.

| Input | Why it matters |
|---|---|
| GSTIN and State or Union territory | Central and State/UT components can apply under corresponding laws, and the relevant State or UT affects annual-return calculations. |
| Return form | GSTR-1, GSTR-3B, GSTR-7, GSTR-9 and GSTR-9C do not all use the same rules. |
| Tax period and filing frequency | Monthly, quarterly and annual returns have different due-date arrangements. |
| Applicable due date | Use the date shown for the registration and period after considering an official extension. A standard date is not automatically the date for every period. |
| Actual filing date | The Portal uses the date on which the return is filed, not merely when data is saved or a draft is prepared. |
| Nil status | Nil GSTR-3B and nil-outward-supply GSTR-1 filings have a different maximum in the notified regime described below. |
| Preceding-year annual aggregate turnover | For the specified GSTR-1 and GSTR-3B caps, the turnover band determines the maximum total fee. |
| Applicable notification or waiver | Notifications can reduce a statutory amount, change a cap, or waive a fee for a form and period. |
Keep the return period, filing acknowledgment and the Portal’s liability calculation together. They are the evidence needed if the displayed amount later needs to be checked.

- Identify the form and period. Select the exact financial year, return period and filing frequency on the GST Portal.
- Confirm the operative due date. Check the Portal date and any notification or extension for that period. Do not substitute a date remembered from another month or another GSTIN.
- Determine the Portal’s delay period. The calculation follows the rule and Portal treatment for that form. Because extensions and form-specific conventions can affect the count, use the Portal’s displayed number rather than relying on an unsourced manual count.
- Apply the notified daily amount and cap. Start with the rule for that form, then apply nil status, turnover band, annual-return treatment and any notification.
- Check both components. A CGST amount and a corresponding SGST or UTGST amount may appear separately. Their combined total is the amount to review, but do not assume that simply doubling a central figure is always correct.
- Check for a waiver or special regime. A notification can apply only to a named form, tax period, taxpayer category or filing window.
- Compare with the Portal liability before payment. If your arithmetic and the displayed amount differ, investigate the period, date, status, turnover category, cap and notification before paying.
What section 47 establishes
Section 47 of the Central Goods and Services Tax Act sets a framework of ₹100 per day, subject to a maximum of ₹5,000, for the covered delayed returns. That statutory text is a starting point, not a complete answer for every current return. Notifications have reduced or capped fees for particular forms and periods, and the corresponding State GST or Union territory law can add a separate component.
#1 Best Overall
For annual returns, section 47(2) states a daily fee of ₹100 and a CGST cap of 0.25% of turnover in the relevant State or Union territory. That 0.25% figure is not a combined national cap. The corresponding State or UT component is governed by the applicable law, and the Portal should be checked for the complete liability.
Current caps reported for GSTR-3B and GSTR-1
The Telangana Commercial Taxes Department’s December 2025 handbook reports the following post-June 2021 maximum total late fees per return for the specified GSTR-3B and GSTR-1 categories. Each total is split equally between CGST and SGST in the handbook.
| Return condition | CGST component | SGST component | Maximum total per return |
|---|---|---|---|
| Nil tax liability in GSTR-3B or nil outward supplies in GSTR-1 | ₹250 | ₹250 | ₹500 |
| Other return; preceding-year annual aggregate turnover up to ₹1.5 crore | ₹1,000 | ₹1,000 | ₹2,000 |
| Other return; turnover above ₹1.5 crore and up to ₹5 crore | ₹2,500 | ₹2,500 | ₹5,000 |
| Other return; turnover above ₹5 crore | ₹5,000 | ₹5,000 | ₹10,000 |
These are maximums, not automatic charges. A return can incur less than the applicable maximum when the notified daily calculation has not reached the cap. The table applies to the forms and periods covered by that handbook; it must not be carried over to GSTR-9, GSTR-9C or another form without checking that form’s rule.
The nil category is defined by the return condition, not by a taxpayer’s general impression that no business occurred. For GSTR-3B, check whether the return has nil tax liability under the applicable rule. For GSTR-1, check whether outward supplies are nil. The filed data and the Portal classification control.
How to use the cap without overcharging yourself
First obtain the Portal’s pre-cap calculation or component amounts. Then compare the combined amount with the applicable row. If the displayed CGST and SGST amounts total more than the row’s maximum, the notified cap should limit the liability for that regime. If they total less, pay the lower calculated amount. Do not replace the Portal’s form-specific daily rate with the ₹100 statutory baseline when a notification supplies a different rate.

Worked calculation examples
The examples below demonstrate the arithmetic and the role of a cap. The daily figures are hypothetical illustrations, not a statement that every period uses those rates. For an actual return, substitute the component amounts shown by the Portal and the notification applicable to that period.
| Case | Illustrative calculation | Cap check | Result to verify on the Portal |
|---|---|---|---|
| Nil GSTR-3B | Portal arithmetic shows ₹180 CGST plus ₹180 SGST for the delayed period, or ₹360 total. | The nil-return maximum in the specified regime is ₹500 total. | ₹360, assuming the return and period fall within that regime and no waiver changes it. |
| Non-nil GSTR-1; turnover up to ₹1.5 crore | Portal arithmetic totals ₹2,400 before the notified cap. | The applicable maximum is ₹2,000 total. | ₹2,000, subject to the form, period and notification being covered. |
| Non-nil GSTR-3B; turnover above ₹5 crore | Portal arithmetic totals ₹6,400. | The applicable maximum is ₹10,000 total. | ₹6,400, because the calculated amount has not reached the maximum. |
| Annual return | Multiply the applicable annual-return daily amount by the delay period under section 47(2), then apply the CGST turnover-based cap and the corresponding State/UT treatment. | Do not use a GSTR-1 or GSTR-3B cap. | Use the annual-return tile and current instructions for the relevant financial year. |
These examples also show why “days late multiplied by ₹100” is not a safe universal answer. The legal baseline, notified reductions, component split and cap must all match the form and period.

Annual returns have their own treatment under section 47(2). The CGST side uses ₹100 per day, with a maximum linked to 0.25% of turnover in the State or Union territory. The complete liability can include the corresponding State or UT component. Because the cap is turnover-based rather than one of the periodic-return caps, a GSTR-3B or GSTR-1 calculation cannot be reused.
When GSTR-9C is required
For financial year 2024–25, GSTN states that where GSTR-9C is required, completing the annual return involves filing both GSTR-9 and GSTR-9C. This makes “GSTR-9 filed” and “annual return completed” potentially different events.
GSTN’s annual-return FAQ gives an example in which GSTR-9 is filed on time but GSTR-9C is filed later. The delayed completion can create a late-fee period for the later filing. Therefore, check whether the Portal marks GSTR-9C as required and treat the pair as one completion workflow. Do not assume that filing GSTR-9 alone stops every annual-return charge.
Annual-return calculation checklist
- Confirm the financial year and the due date for that year.
- Check whether the Portal requires GSTR-9C.
- Record the filing date of each required form and the date on which the complete annual return is treated as filed.
- Use the annual-return daily amount and turnover-based cap, including the applicable CGST and State/UT treatment.
- Read the current annual-return instructions and any year-specific notification before paying.
Due dates, extensions and counting the delay
GST Portal guidance gives standard GSTR-1 dates of the 11th day of the succeeding month for monthly filers and the 13th day of the month after the quarter ends for quarterly filers. Those dates are subject to extensions, so they are reference points rather than guarantees for every filing period.
QRMP taxpayers have separate filing and payment arrangements. The Portal dashboard displays the return tiles and the due dates applicable to the selected registration and period. Use that date, not a calendar copied from another taxpayer.
To avoid an off-by-one error, do not count days from a search-engine result or a private spreadsheet alone. Select the period on the Portal, note the due date shown, and compare it with the filed timestamp. If an extension or waiver has been notified, verify that the Portal has applied it to the exact form and period. Save a screenshot or PDF of the displayed calculation after filing.
Late fee is not interest on tax
Late fee is triggered by filing after the applicable due date. Interest is linked to tax paid late and is calculated separately. A delayed return with unpaid tax can therefore produce two liabilities: late fee for the filing delay and interest for the tax-payment delay.
GSTN’s process guidance treats the two calculations separately. For GSTR-3B, the late fee is system-calculated after the delayed return is filed and is collected in a subsequent GSTR-3B. The system-generated return PDF provides the calculation detail. Review the interest line separately instead of adding both amounts into one undefined “penalty.”

GSTN’s March 2026 notice concerns recomputation of interest for certain February 2026 cases. It should not be described as a general rule that recalculates every late fee. If your issue concerns interest, follow the notice’s scope; if it concerns late fee, check the form-specific late-fee calculation and notification.
How to check and pay the amount on the GST Portal
- Sign in to the GST Portal for the correct GSTIN. Multiple registrations must be handled separately.
- Open the returns dashboard. Select the financial year, tax period and return tile. Confirm that the form shown is the one you intended to file.
- Review the due date and filing status. Look for an extension, waiver or an already filed return before beginning another submission.
- Prepare and validate the return. Resolve invoice, payment, authentication and validation errors before the filing attempt. Saving a draft does not substitute for filing.
- Submit and file using the available authentication method. Note the exact filing date and acknowledgment reference.
- Open the liability or payment view. Review late fee by component, any interest separately, cash-ledger balance and the amount due after credits or payments.
- Compare the amount with the applicable cap. Check nil status, turnover category, form, period and notification. If the Portal’s amount is unexpected, do not pay a guessed figure first.
- Pay and preserve records. Download the filed-return acknowledgment and system-generated PDF showing the calculation.
Labels can change as the Portal is updated. The controlling evidence is the live return tile, the filed acknowledgment and the calculation shown for that GSTIN and period.
Why the amount may look wrong
| Symptom | Checks to perform | Likely correction |
|---|---|---|
| The fee is higher than expected | Verify the selected period, actual filing timestamp, extension, nil classification, turnover band and whether both CGST and SGST/UTGST are included. | Correct the input or obtain the current notification for that period; do not use a different form’s cap. |
| The Portal shows a fee after a waiver was announced | Check the waiver’s exact form, tax period, taxpayer category and filing window. | A general announcement may not cover your return. Use the Portal recomputation or help facility where available. |
| GSTR-3B late fee appears in a later return | Open the subsequent GSTR-3B and its system-generated PDF. | GSTN says the delayed fee is collected through a subsequent GSTR-3B; reconcile the component calculation there. |
| Interest and late fee are shown together | Separate the interest line from the late-fee lines and check whether tax was paid after the due date. | Recalculate each liability independently; do not call the combined amount a single penalty. |
| GSTR-9 was filed but annual-return liability remains | Check whether GSTR-9C is required and whether it has been filed. | Complete the required GSTR-9/GSTR-9C pair and review the annual-return calculation. |
| The Portal will not accept payment or filing | Check authentication, validation messages, cash ledger balance, browser session and any Portal outage notice. | Resolve the technical issue promptly, retain the error reference and file as soon as access is restored. |
How to stop paying late fees repeatedly
Build a registration-level calendar
Maintain one calendar for each GST registration. Record the GSTIN, return form, monthly or quarterly frequency, tax period, Portal due date, assigned owner and backup. A business with several registrations should not rely on one national reminder because the dates and filing status can differ.
Prepare before the filing window closes
Close the books, collect invoices, reconcile outward supplies and confirm tax-payment inputs before the due date. Assign responsibility for data preparation, review and final authentication. A backup person should have access to the required records and signing method.
File before the last safe day
Submit early enough to deal with validation errors, payment failures, digital-signature or authentication problems, and Portal congestion. A completed draft is not a filed return. Wait for the acknowledgment and verify the status after filing.

Review the next GSTR-3B
Because GSTN states that GSTR-3B late fee is collected in a subsequent GSTR-3B, add a post-filing review to the next period’s checklist. Confirm that the prior period’s late-fee lines and any interest are understood before submitting the new return.
Reconcile the liability every month
Compare the Portal’s displayed amount with your internal schedule. Record the due date used, filing date, nil or non-nil status, turnover band, component split, waiver or notification relied upon, payment reference and acknowledgment. This creates an audit trail and makes an unexpected future charge easier to diagnose.
Special situations that require extra care
Nil returns
Nil treatment is form-specific. A nil GSTR-3B condition and nil outward supplies in GSTR-1 are the categories described in the periodic-return cap table. Do not assume that a nil return in another form receives the same maximum.
State and Union territory differences
Central, State and Union territory provisions can operate together. Annual-return caps in particular should not be presented as one all-India amount. Read the component lines and the law applicable to the registration’s State or UT.
Notifications and changing rules
Late-fee amounts, caps and waivers can change by notification. The December 2025 handbook, for example, notes that from November 2024 there is no late fee for a nil GSTR-7 under the cited notification. That example demonstrates why a rule for one form cannot be generalized to another. Confirm the effective period before relying on any waiver.
Quarterly filing
Quarterly filers should use the QRMP instructions and the Portal’s quarterly return tile. The 13th-day GSTR-1 reference applies to the standard quarterly arrangement described in Portal guidance and remains subject to extensions; it does not replace the specific date shown for your period.
Multiple GST registrations
File and reconcile each GSTIN separately. A timely filing for one registration does not cure a late filing for another, even if both belong to the same legal entity.
Final checklist before you pay
- Is this India GST and the correct GSTIN?
- Did you select the correct form, financial year and tax period?
- Did you confirm the Portal due date after extensions?
- Did you use the actual filing date and Portal delay count?
- Did you classify the return correctly as nil or non-nil?
- Did you apply the right turnover band only where that form’s rule requires it?
- Did you check the current notification or waiver for the exact form and period?
- Did you review CGST and SGST/UTGST components separately?
- Did you keep late fee separate from interest on tax?
- Did you download the acknowledgment and system-generated calculation PDF?
The safest answer to “how much is my GST late fee?” is therefore the amount calculated for the exact return on the live GST Portal, reconciled to section 47, the applicable notification, the form-specific cap and the relevant State or UT component. Use that same return-level process every period instead of carrying forward a rate or date from another filing.
