Sending sensitive financial information, such as a completed tax return, through email presents significant security risks. Email communication is generally not encrypted by default, meaning the contents can be intercepted and read by unauthorized individuals or entities during transmission.
The practice of emailing tax returns introduces the potential for identity theft and financial fraud. Compromised tax information can be used to file fraudulent returns, access bank accounts, or open credit lines in the victim’s name. Historically, insecure email practices have been a major source of data breaches and identity theft incidents targeting both individuals and organizations.
