Introduction:
WhatsApp GST notice invalid — this recent Kerala High Court judgment is a major wake-up call for tax officers and taxpayers. This blog breaks down the judgment, its legal basis, and how you can safeguard against invalid notices.
What Was the Case About?
In Kun Motor Company Pvt Ltd v. STO [2024 (76) GSTL 282 (Ker)], the GST officer sent a show cause notice (SCN) to the taxpayer via WhatsApp without following the due process prescribed under Section 169 of the CGST Act, 2017.
The taxpayer didn’t respond—naturally, it wasn’t a legally valid notice. The officer proceeded to pass an ex-parte order and demand tax. The taxpayer challenged the order, and the High Court ruled in their favour.
Legal Provision: Section 169 of CGST Act, 2017
Section 169(1) of the CGST Act lays down specific modes for serving notices:
- By hand delivery or courier
- Registered post or speed post
- Upload on GST portal
- Publication in newspaper (in some cases)
▶️ WhatsApp is not a valid mode.
Kerala High Court’s Observations
- WhatsApp communication is not recognized under CGST Act.
- Just because a message is “seen” doesn’t mean it’s legally served.
- The burden of proof lies with the department to show proper service.
- Natural justice was violated as the taxpayer was denied the chance to respond.
Expert Insight: Why This Matters for You
CA R. Subramanian, tax litigation expert, explains:
“This ruling reiterates that digital convenience cannot override legal procedure. Even if tech is used, it must align with statutory provisions. Otherwise, any demand order based on improper service can be struck down.”
What Should Taxpayers Do?
- Always check your GST portal regularly for official notices
- Notices via WhatsApp or phone messages are not valid — don’t panic
- If served improperly, you can legally challenge the order
- Keep evidence (like lack of email or portal notice) when contesting
