Under QRMP, returns are quarterly but tax dues are paid every month through a challan. Quarterly GSTR-3B is ordinarily due on either the 22nd or 24th of the month after the quarter, depending on the principal place of business.
Those are baseline dates, not guarantees for every period. A government notification can change a deadline, and the GST Portal dashboard shows the date applicable to your taxpayer account and selected return period. Use that live date before treating any calendar entry as final.

Baseline GST compliance calendar
The table below covers the common recurring deadlines for normal and casual registered taxpayers using GSTR-1, and for eligible taxpayers using the Quarterly Return Monthly Payment (QRMP) scheme. Dates are ordinary timings described by the GST Portal; notifications may extend or otherwise change them.

These entries are a baseline for the common calendar, not a complete schedule for every GST form or registration type. The period-specific dashboard on the GST Portal should control your final filing decision.

What GSTR-1 is and who files it
GSTR-1 is the monthly or quarterly statement of outward supplies. It captures sales and other outward-supply information that can feed recipients’ purchase records and related compliance processes. The GST Portal describes it for normal and casual registered taxpayers making outward supplies.
Information commonly reported
Depending on the transaction, GSTR-1 generally includes:
- Invoice-level details for supplies to registered recipients.
- Specified inter-state supplies to unregistered consumers.
- Credit notes and debit notes, including relevant amendments.
- Exports and advances where the applicable tables require them.
- Exempt, nil-rated and non-GST supplies.
- HSN or SAC summaries.
- Specified supplies made through e-commerce operators.
The return is required even when there was no business activity for the period. A nil-activity period is therefore not a reason to leave GSTR-1 unattended; check the portal’s filing requirements and complete the applicable return.

Categories outside this ordinary GSTR-1 calendar
The ordinary schedule should not be applied automatically to composition taxpayers, input service distributors, taxpayers deducting tax at source, e-commerce operators collecting tax at source, or other special registrations whose forms and deadlines differ. Annual returns and other specialized statements also have separate rules. Confirm the form shown for your registration rather than assuming that a GSTR-1 date covers every GST obligation.
Monthly filing versus QRMP: choose the correct cadence
Your first calendar decision is whether the GST Portal has you on a monthly filing frequency or on QRMP. The two arrangements differ not only in the return date but also in when cash leaves the business.

| GSTR-3B | Filed according to the taxpayer’s applicable monthly return schedule. | Filed quarterly, with the location-based quarterly due day. |
| Tax payment | Follow the payment associated with the applicable monthly return process. | Pay tax dues monthly through a challan. |
| Optional interim reporting | IFF is not the relevant QRMP facility. | IFF may be used for specified details in the first two months of a quarter. |
QRMP eligibility in the official FAQ
The QRMP FAQ describes eligibility using PAN-based aggregate annual turnover of up to ₹5 crore in both the current and preceding financial year. The scheme also has filing conditions, including filing the latest GSTR-3B that was due. Meeting the turnover figure alone does not establish eligibility; review the conditions displayed for your account and the current scheme rules.
Because QRMP changes the relationship between returns and payment, businesses should maintain a monthly cash-reserve routine even though the main returns arrive quarterly. Missing the payment cadence can create a compliance problem before the quarterly filing date appears.
How the quarterly GSTR-3B date is determined
For QRMP taxpayers, the quarterly GSTR-3B deadline is tied to the principal place of business. The official advisory divides states and union territories into two groups: one group uses the earlier ordinary day in the post-quarter month, and the other uses the later ordinary day. The baseline dates are shown in the calendar table above.
Why registration location matters
The relevant location is the principal place of business recorded for the GST registration, not the location of a customer, warehouse or accountant. A business with registrations in different jurisdictions should check each registration’s dashboard and deadline rather than applying one date to every GSTIN.
How to handle a changed date
Government notifications can move a deadline for a particular period, state group or return. Treat the 22nd-or-24th pattern as an ordinary timetable only. Before filing, open the return period on the GST Portal and confirm the date displayed for that registration.
IFF: useful optional reporting for QRMP taxpayers
The Invoice Furnishing Facility is an optional QRMP feature. It lets a quarterly filer furnish specified outward-supply details during the first two months of a quarter instead of waiting for the quarterly GSTR-1.
What IFF covers
The facility is limited rather than a complete early GSTR-1. The FAQ identifies specified business-to-business invoice tables and related credit-note or debit-note tables. Use it when early reporting of those eligible documents is useful to your recipients; do not assume every GSTR-1 field can be filed through IFF.
The expiry rule
IFF closes after its monthly due day. If you miss that window, the facility for that month expires. The information can instead be reported through a later IFF, where applicable, or in the quarterly GSTR-1. Because IFF is optional, not using it does not convert a quarterly taxpayer into a monthly filer.
Step-by-step process for meeting each deadline
- Identify the return frequency. Sign in to the GST Portal and verify whether the registration is on a monthly schedule or QRMP. Do not infer the frequency from the previous year’s routine if the account, turnover or scheme status has changed.
- Select the exact financial year and return period. Open the return dashboard, choose the relevant financial year and tax period, and read the due date displayed for that selection. This catches period-specific extensions and scheme changes.
- Confirm the registration location. For QRMP GSTR-3B, check the principal place of business attached to that GSTIN and the location group used for the quarter. If you manage multiple registrations, repeat this check for each one.
- Collect the outward-supply data. Organize registered-recipient invoices, specified inter-state consumer supplies, exports, advances, amendments, credit and debit notes, exempt or nil-rated supplies, HSN or SAC summaries, and applicable e-commerce supplies. The aim is to map each document to the correct GSTR-1 table rather than entering a single unsupported total.
- Prepare GSTR-1 through an available channel. The GST Portal supports direct online entry, its offline tool, or a third-party application connected through a GST Suvidha Provider. Software is an optional process aid; it is not a substitute for checking the government portal or the accuracy of the underlying records.
- File GSTR-1 by the applicable monthly or quarterly day. Use the due date shown for the selected period. If there was no business activity, complete the required nil filing instead of assuming that no transaction means no return.
- Make QRMP payments monthly. If the registration is under QRMP, create the required challan and pay tax dues each month. The quarterly return cadence does not postpone these monthly payment obligations.
- File quarterly GSTR-3B. Submit it by the location-based quarterly due day displayed for the registration. Check the dashboard again if a notification, holiday adjustment or portal advisory may have changed the ordinary date.
- Use IFF only when it fits the reporting need. For either of the first two months in a QRMP quarter, decide whether the specified business-to-business documents should be furnished through IFF. Complete it before its window closes; otherwise plan to report the information in the later permitted return.
- Save the filing evidence. Retain the filed-return acknowledgement, challan details and the records used to populate each table according to your business’s record-keeping policy. This creates a period-by-period trail when figures are reviewed later.
How to use the live GST Portal dashboard
A static calendar is only a planning aid. The portal’s filing page displays the due date applicable to the taxpayer, financial year and return period you select. Make that page your final checkpoint.
Check before preparing data
At the start of each month or quarter, confirm the filing frequency and the period selected in the dashboard. This is especially important after opting into or out of QRMP, changing registration details, or moving between financial years.

Check again before submission
Read the displayed due date immediately before filing and payment. A notification may have extended a deadline, or the portal may show a date that differs from a generic calendar because of the registration’s scheme or location. Record the date you relied on with the filing acknowledgement.
Use notifications as overrides
The ordinary 11th, 13th, 22nd and 24th patterns should never override a later government notification. When the portal advisory and a notification differ, follow the current official instruction for the relevant period and taxpayer group.

Confusing quarterly returns with quarterly payments
QRMP does not mean the business can wait three months to pay. The scheme combines quarterly GSTR-1 and GSTR-3B with monthly challan payments. Put payment checks on the monthly close calendar, separate from the quarter-end return checklist.
Applying one GSTR-3B date to every location
The quarterly GSTR-3B day depends on the principal place of business and the government’s state or union-territory grouping. A multi-registration business should maintain a GSTIN-level calendar.
Treating IFF as mandatory or as a full return
IFF is optional and limited to specified details. It is neither compulsory for every QRMP taxpayer nor a substitute for the quarterly GSTR-1. Decide based on whether early reporting of the eligible documents is useful.

- Helpful in various ways
Assuming no sales means no GSTR-1
The portal says GSTR-1 must still be filed for a period with no business activity. Include nil periods in the compliance calendar.
Using an old date after a notification
Extensions and other changes can apply to a particular period. Always compare your planning calendar with the live dashboard before submitting.
Assuming software determines compliance
Online entry, the official offline tool and third-party ASP applications through GSPs are preparation options. None of them establishes the legal due date independently of the GST Portal and applicable notifications.

Practical planning calendar for a small GST-registered business
A simple operating rhythm reduces last-minute errors without changing the statutory dates:
- Weekly: record invoices, notes, exports, advances and amendments while transaction details are available.
- Month-end: classify documents for GSTR-1 tables and calculate the QRMP challan payment when the registration is on that scheme.
- First two months of a QRMP quarter: decide whether eligible business-to-business documents should go through IFF before its window expires.
- Quarter-end: reconcile the quarter’s outward-supply records, confirm the principal place of business grouping and prepare quarterly GSTR-1 and GSTR-3B.
- Before every submission: open the selected period on the GST Portal, verify the displayed due date and retain the acknowledgement or challan record.
This routine is a management aid, not a new filing rule. The portal’s period-specific date and current notifications remain authoritative.
Limits of this calendar
This guide is intentionally focused on the common regular-taxpayer workflow for GSTR-1, QRMP payments, quarterly GSTR-3B and optional IFF. It does not provide a complete deadline table for composition taxpayers, non-resident taxpayers, input service distributors, TDS or TCS filers, e-commerce operators collecting TCS, annual returns or every special form. Those categories can have different eligibility rules, forms and dates. Check the form and deadline attached to the specific registration before relying on this calendar.
Bottom line
Build your working calendar around the applicable GSTR-1 frequency, the monthly QRMP challan payment when relevant, and the principal-place-of-business rule for quarterly GSTR-3B. Then verify every period on the GST Portal dashboard, because notifications can change the ordinary dates. That final check is what turns a useful reminder into a defensible compliance process.
