GST return framework: electronic common returns, auto population between GSTR 1/2/3, invoice matching, and automatic ITC reversal rules.
The proposal establishes a common electronic GST return regime with self-assessment, separate return forms for distinct taxpayer categories, mandatory electronic Cash, ITC and Tax Liability ledgers, and payment as a prerequisite for valid filing. It prescribes sequential monthly/quarterly filing with specified cut off dates for GSTR 1, GSTR 2 and GSTR 3 to enable auto population and invoice matching, details contents required for each GSTR variant, mandates HSN/SAC reporting tied to turnover, provides a two day reconciliation window between counterparties, automatic reversal of unmatched ITC after two cycles, and allows revisions via debit/credit notes and supplementary documents.

GST electronic payment process uses a single challan (CPIN), three payment modes, and real time CIN reconciliation.
Establishes an end-to-end electronic GST payment system using a GSTN issued common challan with a unique CPIN, three payment modes (internet/card, OTC for small amounts, and NEFT/RTGS via RBI), real time transmission of electronic strings and CIN confirmations from collecting banks/RBI to GSTN, centralized taxpayer cash ledgers on GSTN, e FPBs per bank, and an RBI e kuber accounting and reconciliation workflow with standardized accounting codes for CGST, IGST, Additional Tax and SGST.

GST refund process: streamlined online verification, minimal documentation, CA certification for unjust enrichment, and statutory timelines enforced.
Refunds under the proposed GST regime arise for excess payments, exports (including deemed exports), provisional assessment finalization, pre-deposit in appeals or investigations, supplies to specified international and public bodies, refunds from tax-free or non-GST supplies, carry forward Input Tax Credit, incentives adjustments, and tourist purchases. Claims require online verification with customs for exports, minimal documentation given electronic filings, CA certification to address unjust enrichment where applicable, a one-year filing window from relevant trigger dates, prescribed time-bound processing, automated acknowledgements, electronic disbursement, and mechanisms for review, pre-audit, interest on delayed refunds, and adjustment against outstanding confirmed demands.

GST registration framework ensures PAN-based unique identification, online verification, and deemed approval with migration mechanisms.
Registration under GST is a PAN-based unified process creating a 15 character GSTIN for unique identification; it mandates registration for specified classes (existing taxpayers, persons above turnover threshold, interstate suppliers, casual and non-resident suppliers) and allows state-wise and vertical-specific registrations. Applications are submitted online with prescribed documents, may be processed before receipt of signed summaries, and are subject to online verification and deemed approval after a three working day authority response; migration, composition scheme eligibility, amendment procedures, and rules for surrender or cancellation are integral to the registration lifecycle.

Goods and Services Tax: dual CGST/SGST on a destination based consumption base with invoice credit and a modified bank inter state model.
The Report recommends a dual GST-CGST and SGST-levied concurrently on an identical consumption base under the destination principle, with liabilities computed by the invoice credit method, separate accounting and no cross utilisation of input tax credits, full immediate credit for capital goods, narrow negative list exemptions, specified treatment of SIN goods by dual GST and excise, uniform small dealer threshold exemption (Rs.10 lakh) with an optional composition levy, and inter state trade managed through a Modified Bank Model with a nodal bank and Form GST I for consolidated electronic payment and transaction reporting.

GST: recommend revenue neutral rate 15-15.5% with 12% low rate, 17-18% standard, 40% demerit applies.
Recommend a national GST RNR of 15-15.5% (preferably 15%), derived from adjustments to indirect tax turnover estimates and validated against macro and direct-turnover approaches. Adopt a transitional multi-rate structure: combined lower rate 12%, combined standard rate 17-18% (under 15% RNR), and a combined demerit rate 40% for luxury/sin goods. Require a narrow, common exemptions list, elimination of CVD/SAD exemptions, preservation of input tax credits (including on capital goods), a transparent five year State compensation mechanism, and no administratively complicating state rate bands.

Revenue neutral rate guidance recommends a narrow combined central state band to preserve revenue while limiting exemptions and simplifying GST.
The Report recommends using a Revenue Neutral Rate as an analytical benchmark and advises a narrow combined Centre and states RNR with a preference for the lower end; it proposes conditional rate structures tied to exemptions and special treatment (including demerit taxation), favors a medium term one rate GST with a transitional two rate approach, urges rationalization of exemptions to protect the standard rate and compliance, and calls for Centre state allocation of combined rates, credible compensation mechanisms, and extended monitoring before rate changes.

Goods and Services Tax to subsume existing indirect taxes, broaden the tax base and enable seamless input tax credits.
The proposal designates Goods and Services Tax to subsume state VAT, Central Sales Tax, Central Excise, Service Tax and other indirect levies; excludes alcoholic liquor for human consumption from GST while bringing specified alcohol products within GST and subjecting tobacco to GST alongside Central Excise, with rates to be set by the GST Council. The framework aims to simplify and harmonize indirect taxation, broaden the tax base, and promote compliance via a robust IT-enabled input tax credit mechanism.
