Staggered due dates for GSTR-3B reorganise filing timelines by categorising taxpayers into monthly and quarterly groups.
Revision of the Central Goods and Services Tax Rules instituted a staggered filing regime for Form GSTR-3B from January 2021: monthly filers must file by the twentieth of the following month; quarterly filers are split into two geographic groups filing by the twenty second or the twenty fourth of the month following the quarter.

QRMP scheme quarterly filing option enables IFF-based B2B reporting and auto-population of GSTR-3B liabilities for reconciliation.
Under the QRMP scheme taxpayers may use IFF to furnish B2B invoices for the first two months of a quarter and declare remaining invoices in the quarterly GSTR-1; invoices filed in IFF need not be re-entered and saved/submitted but unfiled records are not treated as liability. Most liability fields in Table 3 of quarterly GSTR-3B are auto-populated from IFF and quarterly GSTR-1, with reverse-charge entries taken from Form GSTR-2B; a PDF of computed liability appears on the GSTR-3B dashboard.

Auto-generation of GSTR-2B for QRMP taxpayers enables quarterly ITC reconciliation and auto-population into GSTR-3B, editable.
System features for QRMP quarterly filing auto-generate Form GSTR-2B from filed IFFs and GSTR-1, showing segregated sections for ITC available and ITC not available and the taxpayer's tax liability; taxpayers can view/download quarterly or monthly views and see advisory cut-off criteria. Table 4 of Form GSTR-3B is auto-populated from the quarterly GSTR-2B, a system-computed GSTR-3B PDF is available, and taxpayers may edit auto-drafted ITC values though the system will warn on significant increases in available ITC or reductions in reversals without preventing filing.

Provisional Net Indirect Tax collections exceed revised estimates and show year on year growth despite pandemic disruption.
Provisional Net Indirect Tax collections for FY 2020 21 exceeded Revised Estimates, achieving 108.2% of the Revised Estimates and showing year on year growth. The release disaggregates results: customs and central excise/service tax (arrears) registered marked increases, while Centre GST receipts were lower than the previous year but above the revised target. The second half recovery and government compliance measures are credited for improved GST receipts; figures remain provisional pending reconciliation.

HSN reporting requirement: invoice HSN must match valid tariff headings; truncated or non tariff codes are rejected.
Taxpayers must report at least the HSN digits mandated by Notifications No. 12/2017 and 78/2020 in accordance with the Customs Tariff: mandated six-digit reporting allows valid six- or eight-digit tariff codes; mandated four-digit reporting allows valid four-, six- or eight-digit tariff codes. HSN entries must exist in the Tariff with corresponding description, unit and GST rate; truncated digit sequences that do not appear as valid tariff headings are invalid and will be rejected. For portal acceptance issues with otherwise valid HSNs, taxpayers should raise tickets via the GST Self-Service Portal under the HSN-related category.

GST Portal functionalities detail module-wise deployments and supporting webinars for taxpayer compliance and guidance resources.
Module-wise functionalities have been deployed on the GST Portal covering Registration, Returns, Advance Ruling, Payment, Refund and other processes, accompanied by webinars and instructional videos on the GSTN YouTube channel. The release provides periodic compilations of these deployments, organized by month or quarter, with direct links for stakeholders to review specific feature releases and supporting guidance materials to assist taxpayer compliance.

E-invoice auto-population delayed; taxpayers should file GSTR-1 using their records and validate HSN on the portal.
Auto-population of e-invoices into GSTR-1 for March 2021 is incomplete; notified taxpayers reporting e-invoices should not wait for auto-population and must prepare and file GSTR-1 by the due date based on their records. HSN validity can be checked on the GST Portal and missing valid HSN entries should be reported via a ticket on the GST Self-Service Portal; updated e-invoice FAQs and a bilingual ready reckoner have been published to aid compliance.

GST on underlying supply clarified under GST: tax triggered at voucher redemption, not on vouchers themselves.
Vouchers function as instruments of consideration for future supplies; they are neither goods nor services and thus are not separately classifiable. Tax treatment follows the character of the underlying supply exchanged for the voucher at redemption, and the time of payment and compliance obligations are governed by the relevant provisions of the GST law applicable to that underlying supply.

Record GST revenue collection signals sustained recovery and larger settlements to central and state governments under the GST framework.
The announcement reports a record gross GST revenue for March 2021, details the composition of receipts across CGST, SGST, IGST and cess, and describes regular and ad hoc IGST settlements between Centre and States/UTs plus a separate compensation release. It attributes revenue growth to recovery in economic activity, higher import and domestic collections, and strengthened compliance through monitoring and cross system data analytics, and provides state wise comparisons showing varied growth rates across jurisdictions.
