GST Assessment Orders Lacking Mandatory Document Identification Number are Legally Invalid and Void Ab Initio

Issue

Whether GST assessment orders passed without a mandatory Document Identification Number (DIN) or Reference Number (RFN), and uploaded solely on the online portal without conventional physical service, are legally sustainable or liable to be set aside.

Facts

  • The petitioner is a registered taxpayer under the Goods and Services Tax (GST) framework.

  • The tax department passed three distinct assessment orders against the petitioner, which were uploaded exclusively onto the GST portal.

  • The petitioner filed a writ petition challenging the validity of these three assessment orders on two major grounds: the absolute absence of a DIN/RFN on the face of the orders, and the lack of service through conventional, physical means.

  • The revenue department defended the process, arguing that uploading the final orders directly onto the taxpayer’s online portal profile constituted valid and completed service under the law.

  • Upon reviewing the official case records, it was conclusively established that the impugned assessment orders did not carry any DIN or RFN.

Decision

  • The High Court noted that the issue was squarely covered by its own binding precedents, which explicitly held that the absence of a mandatory DIN is a patent legal irregularity sufficient to invalidate a tax order.

  • The court observed that taxpayers face widespread, practical difficulties with the online portal notification mechanism, which warrants judicial intervention despite any delays in filing the writ petition.

  • To balance the operational hardships of the taxpayer with the administrative interests of state revenue, the court entertained the petition subject to a pre-deposit condition.

  • The petitioner was directed to deposit 20% of the total disputed tax amount within a strict timeline of six weeks.

  • Consequently, the High Court set aside all three impugned assessment orders and remanded the matter back to the Assessing Officer to pass fresh orders containing a valid DIN after providing the petitioner with a fair opportunity to be heard.

Key Takeaways

  • DIN is a Mandatory Validity Shield: The generation and inclusion of a Document Identification Number (DIN) is a non-negotiable statutory requirement for tax orders. An order completely lacking a DIN is treated as a patent irregularity that invalidates the entire assessment.

  • Portal Upload Risks: Relying blindly on automated portal uploads without ensuring robust delivery or conventional backup service can be viewed as a practical hardship for taxpayers, occasionally justifying direct high court intervention even if there is a delay in filing an appeal.

  • Conditional Remand Balancing Act: When constitutional courts set aside tax demands over critical technical flaws like a missing DIN, they frequently impose a partial pre-deposit condition (such as 20% of the tax) to ensure the taxpayer’s bona fides while granting the department a second chance to pass a legally compliant order.

HIGH COURT OF ANDHRA PRADESH
Vish Wind Infrastructure LLP
v.
Deputy Assistant Commissioner*
R. Raghunandan Rao and T.C.D. Sekhar, JJ.
WRIT PETITION NO. 25760 of 2025
APRIL  29, 2026
J.N Venkata Suresh Kumar, learned counsel for the Petitioner.
ORDER
R. Raghunandan Rao, J. – Heard Sri J. N. Venkata Suresh Kumar, learned counsel appearing for the petitioner and the learned Government Pleader for Commercial Tax appearing for the respondents.
2. The petitioner herein has approached this Court, challenging the orders, passed by the respondent authorities, dated 02.09.2023, 11.09.2023 and 30.12.2023 on the ground that the said orders does not contain a Document Identification Number (DIN) or RFN number and the same is vitiated by the lack of such numbers.
3. This Court had considered this issue earlier in Cluster Enterprises v. Deputy Asstt. Commissioner (ST)-2 [2024]  (Andhra Pradesh)/[2024] 105 GST 738 (Andhra Pradesh)/[2024] 88 GSTL 179 (Andhra Pradesh) and in Sai Manikanta Electrical Contractors v. Deputy Commissioner, Special Circle, Visakhapatnam [2024]  (Andhra Pradesh)/[2024] 105 GST 393 (Andhra Pradesh)/[2024] 88 GSTL 303 (Andhra Pradesh) and had held that the absence of a DIN number would be sufficient to invalidate the said orders.
4. However, the learned Government Pleader for Commercial Taxes, appearing for the respondents, would contend that the petitioner has approached this Court with inordinate delay and such delay has not been properly explained.
5. The learned counsel for the petitioner would submit that the said orders had not been served on the petitioner, in the conventional method and the respondents are claiming that these orders are served on the petitioner by uploading the same in the portal.
6. The learned Government Pleader, on the other hand, would contend that Section 169 (1) (d) of the GST Act, 2017 prescribes that the uploading of the orders, is the portal, is a method of service, on the registered persons and in that view of the matter, it must be held that service has been effected on the petitioner.
7. The Hon’ble High Court of Allahabad in Bambino Agro Industries Ltd v. State of Uttar Pradesh [2025] [2026] 105 GSTL 280 (Allahabad)/ Writ Tax No.2707 of 2025, had held that uploading the order in the portal, mentioned by the GST Authorities, would not be sufficient service of the order on the registered person. This Court has taken a contrary view in Smt. Harini v. Kumar Milan G.K. [W.P. No. 5397 of 2026, dated 21-2-2026].
8. However, the fact remains that a very large number of registered persons have approached this Court with the contention that they were unable to access the portal either on account of their ignorance or on account of the fact that the persons, authorized by them, to act on their behalf, are not informing them of such orders. In the normal course, this Court would not accept such a contention as neither ignorance of law nor the inability to access the portal, could have been accepted as a sufficient cause for condoning the delay in approaching this Court.
9. This Court is also not unaware of the practical difficulties that have arisen on account of the introduction of the GST regime and the introduction of the online mechanism, under this regime, for the administration of tax collection, etc.
10. Keeping in view the hardships that are being faced by various registered persons, especially in cases where the orders suffer from patent irregularities, the impugned orders of assessment would have to be set aside.
11. In the circumstances, with a view to balance both the difficulties being faced by the registered persons and the need for the State to maintain its administration of tax collection, it would be appropriate that writ petitions, filed by such registered persons, with delay, can be considered, subject to the registered persons paying 20% of the disputed tax. We are also fortified, in this course of action, in view of the Judgment of the Hon’ble High Court of Madras in Sathiah Ramesh v. Deputy Commissioner (State Tax) (Madras)/W.P. No. 1474 of 2026.
12. In these circumstances, keeping in view the fact that the present orders, under challenge, suffer from an inherent defect of absence of a DIN number, the same is set aside and the assessment is remanded back to the Assessing Officer to pass appropriate orders, after giving due opportunity of hearing, available to the petitioner, under the provisions of the GST Act. This order is subject to the condition of the petitioner depositing 20% of the disputed tax, within a period of six (06) weeks. Such deposit shall abide by the decision in the order of assessment. Any payment made or any amount recovered from the petitioner, after the passing of the impugned orders, shall be adjusted against the aforesaid 20%.
13. Needless to say, the period from the date of filling of this Writ Petition till the date of receipt of this order by the Assessing Officer, shall be excluded for the purposes of limitation and all issues are left open to be raised by the petitioner before the Assessing Officer.
14. Accordingly, this Writ Petition is disposed of. There shall be no order as to costs.
15. As a sequel, pending miscellaneous applications, if any, shall stand closed.
