The Goods and Services Tax (GST) launched in India in 2017 to unify indirect taxes has transformed into a compliance framework driven by digital tools. The 2025 reform package, known as GST 2.0, redirects attention away from a narrow finance-or-indirect-tax remit. Today, adherence to GST rules is a cross-functional imperative that engages finance, information technology, procurement, sales, supply-chain units and senior executives.
Since its inception, the count of GST registrants has risen sharply. The tally of entities rose from roughly 60 lakhs in 2017 to more than 1.64 crore by April 2026, signalling deeper economic formalisation. Correspondingly, GST receipts have grown in step with GDP, now forming a key revenue stream for the treasury. Between April and December 2025, total GST collections amounted to approximately INR 17.4 lakh crore, a 6.7% increase over the prior year. During the same interval, e-way-bill issuances climbed 21% , reflecting heightened transactional volume.
Although the September 2025 revision of tax rates is seen by some as a step toward a two-rate structure, it also creates fresh operational hurdles for companies. Modifying rates touches thousands of product entries, alters customer and supplier records, tax classifications, price lists, invoices, credit notes, ERP configurations and reporting routines. A misplaced rate in an ERP can produce faulty invoices.
An erroneous GSTIN may alter tax treatment and jeopardise input-tax credit. Using obsolete HSN or SAC codes can generate reporting mismatches. Not issuing an e-invoice according to the prescribed format can render a transaction void. Consequently, adherence now hinges on the accuracy of data and the robustness of technology systems. Missteps can trigger monetary losses as well as protracted appeals and arbitration.
System Integration And Operational Responsibility
The e-invoicing mechanism exemplifies the new compliance architecture. Rolled out gradually beginning in October 2020, the requirement now covers firms whose total yearly turnover reaches INR 5 crore or more, subject to relevant criteria. The Invoice Registration Portal (IRP) captures invoice data, issues an Invoice Reference Number (IRN) and creates a digitally signed QR code. By linking a company’s ERP or billing solution straight to government systems, the process transcends a simple tax-return function.
Traditionally, GST compliance fell to tax specialists and finance departments. Within a digital framework, that model no longer suffices. Chief information officers now have to guarantee that ERP platforms, integration layers, APIs and supporting infrastructure consistently uphold compliance obligations. Procurement and sales units depend on correct GSTINs and transaction details, while operations require seamless e-invoice and e-way-bill handling. This creates a collective duty for compliance. For sizable firms employing SAP or comparable ERP suites, GST adherence is no longer confined to a separate return-filing tool; it is woven into order-to-cash, procure-to-pay, logistics and accounting workflows.
