Finin2min Tax DeskยทJune 2026ยท9 min readAUTH NOTICEValidated: 17 June 2026

Before responding to any tax notice received by email, post or WhatsApp-forwarded PDF, verify authenticity. The Income Tax portal provides an authentication service for notices/orders.

Detailed analysis

Why authentication comes first
Tax scams and fake demand notices can look convincing. Before payment or document upload, verify notice/order through the official portal, check DIN/reference, PAN, assessment year and whether the same item appears under e-Proceedings or portal worklist.

Practical example

Example
You receive an email asking to pay โ‚น48,500 with a PDF notice and bank account details. Do not transfer. Verify notice/order on the Income Tax e-Filing portal, check DIN, inspect sender domain, and confirm whether demand appears in your account.
