Workflow in 2 Minutes

Use IGST section 19 and corresponding CGST/UTGST relief; preserve original payment and re-payment/refund chain.

Decision sequence

  • Freeze the relevant date and legal entity/registration.
  • Classify the supply, product, service, machine or process.
  • Apply the parent Act and exact special rule before the general rule.
  • Map rate/exemption/RCM/ECO/cess and connected form.
  • Reconcile books, customs/production/location evidence and portal data.
  • Prepare exception log, reviewer sign-off and litigation note.

Worked control example

A supply was treated as intra-State and CGST/SGST was paid, but later evidence establishes inter-State supply. The taxpayer pays IGST and follows the statutory refund/relief route with both payment trails.

Evidence pack

  • Executed contract / purchase order
  • Invoice and tax head
  • GSTIN and location evidence
  • Shipping/customs/SEZ or machine records
  • Rate/notification and computation sheet
  • Returns, challans and acknowledgements
  • Review note and source archive

Practical Q&A

What is the first control?

Fix the transaction, manufacture or import date and identify the legally relevant locations, product/service classification and liable person.

What is the minimum evidence file?

Act/Rule/notification sources, contract and invoice, location or production evidence, calculation, return/form acknowledgement and reviewer approval.

Can a portal result determine the law?

No. Portal treatment is operational evidence; the Act, Rules, notifications and binding judgments govern.

OPERATING CONTROL

Law vs system

This transaction workflow must be reconciled to the Act, Rules and notified forms. Portal behaviour or an advisory can explain implementation but cannot override a statutory provision or Gazette instrument.

Evidence pack

Retain source records relevant to the step: acknowledgement/reference number, submitted JSON/PDF, ledgers, invoice/e-invoice/e-way-bill records, notices/orders, screenshots only where needed, and system/error tickets.

Reconciliation

Cross-check the portal result with books/ERP, return period, GSTIN, document identifiers, tax head, tax amount and downstream return/ledger effect.

Exception workflow

  1. Identify the legal deadline or condition independently of the portal display.
  2. Reconcile master data and transaction values before submission.
  3. Save acknowledgement and the exact filed/generated artefact.
  4. Investigate any mismatch, rejected record, blocked action or missing auto-population; do not overwrite the audit trail.
  5. Escalate through the official grievance/help route where the system prevents a legally required action and preserve evidence of the attempt.

Source and review trail

Use the current official instrument, portal or regulator publication before acting. This panel separates the category authority from page-specific references.
