GST tax invoice rules require specified invoice particulars, timing, and formats for supplies, including special cases and delivery challans.
Rules prescribe mandatory contents and formats for tax invoices, bills of supply, receipt vouchers, revised invoices, credit/debit notes, ISD invoices and delivery challans, including supplier/recipient identification, unique serial numbers, HSN/Accounting Codes, taxable values, tax rates, place of supply, reverse charge indication and signatures; timing and triplicate/duplicate format requirements for goods and services; consolidated invoicing for unregistered recipients; export endorsements; and procedural particulars for delivery challans and ISD credit distribution.

GST input tax credit rules require specified documents, monthly reporting, turnover-based ISD distribution, and reversals for unpaid supplier consideration.
The draft rules require specified documents and FORM GSTR-2 reporting to claim Input Tax Credit, disallow credit where tax was paid under orders for fraud or suppression, and mandate reversal and interest where supplier consideration is unpaid after 180 days. Banking/financial institutions have special credit limitations and a 50% admissibility rule for remaining input tax. ISDs must distribute credit monthly via FORM GSTR-6 using a turnover-proportionate formula, issue ISD invoices/credit notes, and follow prescribed apportionment on adjustments. Capital goods and stock-related credits are subject to amortisation, five-year attribution, declaration (FORM GST ITC-01), and annual reconciliation with adjustments to output tax.

GST transitional rules allow registered persons to claim input tax credit via FORM GST TRAN-1 within sixty days.
Registered persons must electronically submit FORM GST TRAN-1 within sixty days to claim input tax credit on carried-forward tax or stock at the appointed day, itemising prior-law claims, supporting declarations and, where applicable, capital goods and stock details; credits are to be credited to the electronic credit ledger (FORM GST PMT-2) and may be subject to verification and recovery proceedings.

GST value of supply rules prioritise open market value, then known monetary equivalents, like for like comparison, cost mark up, and residual methods.
Value of supply is determined by a hierarchy: open market value; if unavailable, monetary consideration plus known monetary equivalent of non-monetary consideration; or value of supplies of like kind and quality; failing those, application of the cost-based rule (110% of cost) or the residual rule. Special provisions treat related party supplies (invoice deemed open market value where recipient can claim full input tax credit), agent-mediated supplies (option for 90% of recipient's unrelated supply price), and bespoke valuation methods for currency exchange, air ticketing, life insurance, second hand goods margin, vouchers, and exclusions for expenditure by a supplier acting as a pure agent when specified conditions are met.

Composition levy procedures require electronic intimation, stock disclosures, eligibility compliance, and specified withdrawal processes.
The composition levy is elected by electronic intimation (FORM GST CMP-01, CMP-02 or Part B of REG-01) with required stock and inward-supply disclosures (FORM GST CMP-03, ITC-3). Effectiveness of the option depends on filing timing; one PAN-wide intimation covers all business locations. Eligibility excludes casual and non-resident taxpayers, restricts certain sourced stocks, requires tax on supplies from unregistered persons, mandates status display on bills and premises, and prescribes withdrawal, show cause and stock-declaration procedures (CMP-04 to CMP-07 and ITC-01).

Information exchange mechanism between tax IT systems enables integrated GST data processing and front-end taxpayer services.
Project Saksham funds establishment of an information exchange mechanism linking CBEC and GSTN data centres via pre-agreed APIs or secure message-exchange methods so CBEC can receive and process registration, returns and payment data transmitted by GSTN, act as front-end for audit, appeal and investigation modules, and return CBEC actions to the GSTN portal; the project maintains that there is no functional overlap between CBEC and GSTN systems.

GST reform can be used to curb illegal cigarette trade while protecting farmers and formal industry revenue.
GST offers a regulatory and fiscal mechanism to address illegal cigarette trade by aligning taxation, compliance and enforcement across the supply chain. The Tobacco Institute of India urges using the tax framework to strengthen controls on production, distribution and sale, reduce smuggling and illicit manufacture, support duty-paid manufacturers and increase government revenue while calibrating measures to protect distressed tobacco farmers.

Goods and Services Tax rollout advances after approval of supplementary laws establishing multi-tier rates and temporary cess for state compensation.
Approval of four supplementary enactments establishes the legislative framework for a nationwide Goods and Services Tax regime, subsuming central excise, service tax, VAT and other local levies into a unified indirect tax system. The scheme creates parallel Central and State GST laws, a compensation statute funded by a transient cess to offset state revenue losses, and vests rate classification and sectoral inclusion decisions with the GST Council, which implements a multi-tier structure and exemption for essential food items.

Goods and Services Tax framework establishes dual Centre State levies with a council for consensus and a compensation cess mechanism.
The proposed four bill GST package creates a dual Centre State indirect tax architecture while preserving current aggregate tax rates to avoid inflation. It substitutes central and state levies with a Central GST, an Integrated GST for inter state supplies, State GSTs and a Union Territory GST, and establishes a compensation cess on specified luxury and sin goods to fund temporary revenue compensation to States. Policy decisions and rate classification are to be taken by the GST Council on a consensus, federal model.

Goods and Services Tax reform aims to create a single national tax framework, subject to parliamentary consideration and consensus-building.

GST legislation: party seeks amendments and constructive opposition while pressing for farmers' distress and loan waiver advocacy.
The GST Bills are regarded as unacceptable in current form and the party will seek amendments while maintaining a constructive opposition stance. MPs were instructed to raise public concerns about the tax legislation in Parliament without appearing opposed to tax reform, and to link scrutiny of the GST measures with advocacy for farmers' distress and a farm loan waiver.

Shared sovereignty in GST: government seeks consensus passage to establish a one nation one tax regime and compensation law.
The government proposes four GST measures - Central GST, Integrated GST, Union Territory GST and a Compensation Law - to establish a one nation one tax regime founded on the principle of shared sovereignty; these measures were drafted after detailed discussions in the GST Council comprising all states and the government seeks to pass them through consensus while including a compensation arrangement to address transitional revenue concerns.

Provisional ID issuance: GST migration requires one state based credential per PAN and helpdesk escalation for portal errors.
Guidance on GST migration procedures: one Provisional ID and access token is issued per PAN per State irrespective of number of legacy registrations; additional premises may be added as Additional Place of Business. Addressed enrolment problems include token formatting, OTP delivery issues, login activation errors, DSC registration mismatches, and inability to amend submitted Enrolment Applications until post implementation; taxpayers are advised to use prescribed helpdesk channels for technical investigation and resolution.

Maximum GST rate cap enabled with anti profiteering authority, strengthened tax enforcement and e commerce tax collection.
Four complementary GST enactments establish the indirect tax architecture: CGST to consolidate central levies, SGST as mirror state legislation, IGST for inter state supplies, and a Compensation to States law to offset transitional revenue shortfalls. The scheme enables a maximum combined GST rate while providing for a multi tier operative rate structure, a composition regime for small taxpayers, e commerce tax collection at source, an anti profiteering authority, criminal enforcement measures for evasion, and a capped cess funded compensation mechanism with periodic disbursements.

Union territory GST: levy on intra State supplies, reverse charge rules, input tax credit order, and transitional migration provisions.
The Bill levies a Union territory tax on intra State supplies within specified Union territories, sets rates (not exceeding twenty per cent), enables reverse charge and electronic commerce operator liabilities, prescribes order of utilisation and transfer of electronic input tax credits between integrated, central and Union territory tax, empowers appointment and authorisation of Commissioners and officers (including authorising central tax officers as proper officers), and establishes detailed transitional arrangements for migration of existing taxpayers, carry forward of prior law credits, job work, refunds, recovery and application of Central GST provisions mutatis mutandis.

Integrated goods and services tax introduced for inter State supplies, imports, place of supply rules, zero rating and tax apportionment.
The Act levies an integrated goods and services tax on inter State supplies and imports, establishes administrative powers and definitions, sets detailed tests for inter State versus intra State classification and place of supply for goods and services (including online and cross border services), provides reverse charge and electronic commerce operator liability rules, permits exemptions and tourist refunds, creates zero rating options for exports and Special Economic Zone supplies with refund mechanisms, and prescribes apportionment, settlement and transfer of integrated tax and input tax credit between Central, State and Union territory accounts, while applying key provisions of the Central Goods and Services Tax Act by adaptation.

Goods and Services Tax compensation: States receive provisional bi monthly payments for revenue shortfall funded by a specified compensation cess.
The Act provides temporary compensation to States for revenue loss from GST implementation by using 2015-16 as the base year and a 14% projected growth rate to compute projected revenues; actual revenue comprises net State tax receipts, apportioned integrated tax and specified subsumed collections certified by auditors. Compensation equals the gap between projected and actual revenue, paid provisionally every two months and finally adjusted after audited figures. A compensation cess on specified supplies finances a non lapsable Compensation Fund from which all payments are made; unutilised balances after the transition period are equally shared between Centre and States.

Central GST: levy on intra State supplies with registration, input tax credit, returns, payment and enforcement rules.
The Bill establishes a central goods and services tax on intra State supplies, defining "supply" and prescribing valuation and time of supply rules; it sets registration thresholds and obligations, invoicing and record keeping requirements; creates an input tax credit regime with eligibility, restrictions and apportionment rules (including job work and Input Service Distributor mechanisms); and prescribes electronic returns, matching procedures, payment and refund mechanisms together with administrative, assessment, enforcement and appellate structures.

Goods and Services Tax introduced to create a unified tax regime requiring parliamentary and state legislative approval.
The central government tabled four bills to implement the Goods and Services Tax, creating separate central, integrated, union territory and compensation measures to merge central and state indirect levies into a unified tax regime. The proposals establish a multi-tiered rate framework with an additional cess on certain demerit goods, and link rollout to parliamentary approval and separate state legislature consents, while the introduction sparked Opposition objections about timing and adequacy of scrutiny.
