Verify Income Tax Notice Authenticity Before Responding
During the income tax filing season, taxpayers receive notices.
It's important to verify if these notices are real before responding.
Fraudsters send fake notices to trick people into giving personal information or making payments.
To check if a notice is real, look for a unique Document Identification Number (DIN).
You can verify the notice using your PAN or DIN on the Income Tax e-filing portal without logging in.
An OTP is sent to your mobile number to confirm the notice's authenticity.
This helps taxpayers avoid scams and respond only to legitimate notices.
Income tax notices must be verified for authenticity before responding.
Fraudsters use fake notices to scam taxpayers.
All official communications since 1 October 2019 have a unique DIN.
Taxpayers can verify notices using PAN or DIN on the Income Tax e-filing portal.
An OTP is sent to the provided mobile number for verification.
