Andhra Pradesh High Court Sets Aside GST Assessment Order for Absence of Document Identification Number (DIN)

Case Overview

Case Name: Kagga Pandu Ranga Rao Vs Assistant Commissioner (ST) (Andhra Pradesh High Court)

Forum: Andhra Pradesh High Court

Relevant Legislation: Goods and Services Tax Act, 2017

Assessment Period Under Challenge: April 2018 to March 2023

Background and Facts of the Case

A writ petition was filed before the Andhra Pradesh High Court by the assessee, Kagga Pandu Ranga Rao, assailing an assessment order dated 31.12.2025 passed by the Assistant Commissioner (ST) under the Goods and Services Tax Act, 2017, covering the assessment period from April 2018 to March 2023.

The impugned order had been issued in Form GST DRC-07 and was uploaded on the GST portal. The assessee raised multiple grounds of challenge against this order. Among the several objections raised, the most critical ground was that the assessment order in question did not bear a Document Identification Number (DIN) — a mandatory requirement under the framework established by the Central Board of Indirect Taxes and Customs (CBIC).

The matter was taken up for hearing with the consent of both parties and was disposed of at the stage of admission itself, reflecting the straightforward nature of the legal issue involved.

What is a DIN and Why Does It Matter?

The Concept of Document Identification Number

The Document Identification Number (DIN) is a unique computer-generated identifier that is required to be mandatorily quoted on all communications, notices, orders, and other documents issued by tax authorities under the GST framework. Its purpose is to ensure:

  • Transparency in official communications between tax authorities and assessees
  • Traceability of every document issued within the GST system
  • Accountability on the part of tax officers issuing such documents
  • Prevention of fake or fabricated orders being served upon assessees

CBIC Circular Mandating DIN

The CBIC issued Circular No. 128/47/2019-GST dated 23.12.2019, which made it compulsory for all GST-related communications and orders to carry a DIN. This circular formed the bedrock of several judicial pronouncements that have consistently held that absence of a DIN renders an order legally void and non-existent.

The mandate of DIN in GST proceedings is not a mere procedural technicality — it goes to the root of the validity of the document itself and has been recognized as such by the Supreme Court of India.

Admission by the Government Pleader

A significant development during the proceedings was the frank concession made by the learned Government Pleader for Commercial Tax, Mr. M. Venkata Krishna Rao, who candidly admitted before the Court that the impugned assessment order did not bear a DIN. This admission effectively settled the primary factual question before the Court, leaving only the legal consequence to be determined.
