According to the IRS, taxpayers can protect themselves against identity theft by using the following six tips.
Always use security software. This software should have firewall and anti-virus protections.
Use strong, unique passwords. They should also consider using a password manager.
Learn to recognize and avoid phishing emails, threatening calls and texts from thieves. These scammers pose as legitimate organizations such as banks, credit card companies, and even the IRS.
Don't click on links in unsolicited emails or messages from unknown senders. People shouldn't click on links or download attachments from emails that seem suspicious, even if they appear to be from senders they know.
Protect personal information and that of any dependents. For example, people shouldn't routinely carry around their Social Security cards. They should also make sure tax records are secure.
Get an Identity Protection PIN. The Identity Protection PIN is a six-digit code known only to the taxpayer and to the IRS that helps prevent identity thieves from filing fraudulent tax returns using a taxpayer's personally identifiable information.
